Has been.

Next, the operation of the liquid separation device of this embodiment will be described.
First, based on the operator's operation, the control means drives the motor 12 to rotate the impeller 11. The suction action by the rotation of the impeller 11 reaches the inlet 5 through the first vent 7a and the first chamber A of the partition side wall 7, so that mist-containing air existing outside is introduced from the inlet 5 into the apparatus. Sucked.

  Mist-containing air sucked from the inflow port 5 diffuses in the first chamber A in the radial direction, and gradually penetrates the second separation member 9 while repeatedly colliding with the wall surface of the second separation member 9. Flows to the outside of the second separation member 9. Due to the collision between the mist-containing air and the second separation member 9 when passing through the second separation member 9, a part of the contained mist adheres to the wall surface of the second separation member 9, and the outside of the second separation member 9. Separated from the mist-containing air flowing into the

  And most of the mist-containing air that flows to the outside of the second separation member 9 bypasses the rectifying member 10 and flows to the first vent 7a and the second chamber B side. Further, part of the mist-containing air that has flowed to the outside of the second separation member 9 passes through the through hole of the rectifying member 10 and flows toward the first vent 7a and the second chamber B.

  Next, the mist-containing air that has flowed into the second chamber B through the first vent 7 a is sucked in the axial direction toward the impeller 11 and discharged outward in the radial direction of the impeller 11. The mist-containing air discharged from the impeller 11 passes through the outer peripheral side separation member 13a, the front side separation member 13b, and the rear side separation member 13c surrounding the impeller 11, and flows to the outside of the outer peripheral side separation member 13a. 7 flows into the third chamber C through the second vent hole 7b formed in the outer wall 7. Here, when the mist-containing air passes through the outer peripheral side separation member 13a, the front side separation member 13b, and the rear side separation member 13c, the contained mist is separated as in the case of passing through the second separation member 9.

  The mist-containing air that has flowed into the third chamber C flows to the first side wall 3 side (front side) while turning inside the cylindrical third chamber C due to the influence of the rotation of the impeller 11. Therefore, as shown by the arrows in FIGS. 1 and 2, the mist-containing air flows in the third chamber C while passing through the third separation member 14 disposed in the third chamber C many times. Therefore, in the third chamber C, every time the mist-containing air passes through the third separation member 14, the contained mist is separated in the same manner as when passing through the second separation member 9. Furthermore, the mist-containing air that has reached the first side wall 3 side of the third chamber C finally passes through the fourth separation member 15 and is discharged from the discharge port 6 to the outside of the apparatus. Even when passing through the fourth separation member 15, the contained mist is separated in the same manner as when passing through the second separation member 9. And mist containing air turns into the clean air from which the containing mist was removed by each separation member, and is discharged | emitted from the discharge port 6 to the exterior of an apparatus.

  On the other hand, the mist adhering to the wall surface of the second separating member 9 gradually becomes droplets and falls on the bottom portion of the partition peripheral wall 8 along the wall surface by its own weight. The mist-derived liquid that has dropped onto the bottom portion of the partition peripheral wall 8 is discharged into the outer drainage pipe 16 through the inner drainage pipe 17. Similarly, the mist adhering to the wall surfaces of the outer peripheral side separation member 13a, the front side separation member 13b, the rear side separation member 13c, and the third separation member 14 gradually becomes droplets and travels along the wall surface by its own weight. It falls to the bottom part of the peripheral wall 2 of the casing 1. Then, the liquid derived from mist that has dropped to the bottom portion of the peripheral wall 2 is discharged into the outer drainage pipe 16. The mist-derived liquid discharged into the outer drainage pipe 16 is further discharged into a predetermined storage section by opening the valve 18.

  Further, in the mist removing apparatus of the present embodiment, the deodorant supplying means and the clogging preventing means are operated when the motor 12 is driven. Compressed air supplied from the compressed air supply device 20 to each supply pipe, deodorant liquid supplied from the deodorant liquid supply device 21 to each supply pipe, and mixed with the deodorant liquid from the injection port 19c of the supply pipe Air is injected into the first chamber A, the second chamber B, and the third chamber. Due to the pressure of the compressed air, the mist-derived liquid adhering so as to block the through holes of the separation members is blown off. Further, the mist-containing air and the device are deodorized by the deodorant liquid mixed with the compressed air. In addition, the deodorant liquid mixed in compressed air is isolate | separated from the mist containing air which flows in the apparatus similarly to the mist in mist containing air.

(5) The third separating member 14 has a V-shaped cross section and is formed in a plate shape extending in the axial direction of the third chamber C. According to the above configuration, the mist-containing air swirling in the third chamber C collides with the wall surface of the third separation member 14 twice when passing through the single third separation member 14, and therefore has an I-shaped cross section. As compared with the case where the third separation member 14 is used, the separation effect is doubled.

  (6) A plate-like fourth separation member 15 that closes the inner opening of the discharge port 6 is arranged in the third chamber C. According to the above configuration, the mist-containing air that has reached the first side wall 3 side of the third chamber C collides with the fourth separation member 15 when being discharged from the discharge port 6.

When supplied to 54 a and each peripheral wall injection port 54 b, compressed air containing a deodorizing liquid is injected into the casing 31.

  The compressed air supply device and the deodorizing liquid supply device are connected to a control device (not shown), and based on signals from the control means, the third supply pipe 51, the fourth supply pipe 52, the side wall injection port 54a, and the peripheral wall injection. The operation of supplying compressed air and deodorant liquid to the port 54b is controlled. In the present embodiment, the clogging prevention means is configured by the control means, the compressed air supply device, the third supply pipe 51, the fourth supply pipe 52, the side wall injection port 54a, and the peripheral wall injection port 54b. And a deodorizing means is comprised by the control means, the deodorizing liquid supply apparatus, the 3rd supply pipe | tube 51, the 4th supply pipe | tube 52, the side wall injection port 54a, and the surrounding wall injection port 54b.

Next, the operation of this embodiment will be described.
First, the control means drives the first motor M1 based on the operator's operation to rotate the impeller 38. The suction action caused by the rotation of the impeller 38 reaches the inlet 35 through the vent 37a of the partition wall 37 and the partition wall 37, so that mist-containing air existing outside is sucked into the apparatus from the inlet 35. Is done.

  The mist-containing air sucked from the inflow port 35 passes through the rotation separating member 41 in the partition wall 37 from the space on the front side (first side wall 33 side) to the rear side (second side wall 34 side). ). The mist-containing air that flows to the rear side of the partition side wall 39 is sucked into the impeller 38 through a vent 37 a formed in the partition wall 37. At this time, the mist-containing air passes through the wall surface of the first member 42 of the rotary separation member 41. However, due to the collision between the mist-containing air and the first member 42, a part of the contained mist is first. The mist-containing air that adheres to the wall surface of the one member 42 and flows to the rear side of the partition side wall 39 is separated. The presence of the partition side wall 39 in the partition wall 37 restricts the mist-containing air sucked from the inlet 35 from being directly sucked into the impeller 38 without passing through the rotary separation member 41. Yes.

  Next, the mist-containing air sucked into the impeller 38 is discharged outward in the radial direction of the impeller 38, and the partition wall 37 in the casing 31 is repeatedly collided with the outer peripheral separating member 46 and the rear separating member 47. It flows to the front side through the space outside. When the mist-containing air passes through the outer circumferential separation member 46 and the rear separation member 47, the contained mist is separated in the same manner as when passing through the first member 42 of the rotary separation member 41. And mist containing air turns into the clean air from which the containing mist was removed by each separation member, and is discharged | emitted from the discharge port 36 outside the apparatus.

  On the other hand, the mist adhering to the wall surface of the first member 42 of the rotation separating member 41 gradually becomes a droplet, falls on the wall surface by its own weight, and falls to the lower part of the partition wall 37. The mist-derived liquid that has fallen to the lower portion of the partition wall 37 flows to the lower portion of the peripheral wall 32 of the casing 31 through the inner drainage pipe 49 and is discharged into the outer drainage pipe 48. And the liquid derived from the mist discharged | emitted in the outer side drainage pipe 16 is further discharged | emitted by opening the valve | bulb 50 to a predetermined | prescribed storage part.

  Further, in the mist removing apparatus of the present embodiment, the deodorizing liquid supply means and the clogging prevention means are operated when the first motor M1 is driven. Compressed air is supplied from the compressed air supply device to each supply pipe, each side wall injection port 54a and each peripheral wall injection port 54b, and from the deodorizing liquid supply device to each supply pipe, each side wall injection port 54a and each peripheral wall injection port 54b. Supply deodorant. Then, compressed air mixed with deodorant liquid is injected into the casing 31 from the injection port 53, the side wall injection ports 54 a, and the peripheral wall injection ports 54 b of each supply pipe.

  Due to the pressure of the compressed air, the mist-derived liquid adhering so as to close the through holes of the first member 42, the outer periphery separating member 46, and the rear separating member 47 of the rotary separating member 41 is blown away. Specifically, the mist-derived liquid attached to the first member 42 of the rotary separation member 41 is blown off by the compressed air injected from the injection ports 53 of the third supply pipe 51 and the fourth supply pipe 52. And the liquid derived from the mist adhering to the outer periphery separation member 46 and the rear side separation member 47 is blown off by the compressed air injected from each side wall injection port 54a and each peripheral wall injection port 54b.

  Further, in the mist removing apparatus of the present embodiment, when the clogging preventing means is operated, the second motor M2 is driven to control the rotation separation member 41 and the fourth supply pipe 52 to rotate. By rotating the rotation separation member 41, the positional relationship between each portion of the circumferential wall of the first member 42 in the rotation separation member 41 and the injection port 53 of the third supply pipe 51 relatively changes. Thereby, the compressed air comes into contact with the entire peripheral wall of the first member 42, and the action of removing the adhered mist by the clogging preventing means is exerted on the entire peripheral wall of the first member 42.

  Also in the second embodiment, the same effects as (1) to (3), (7), and (8) in the first embodiment can be obtained. In the second embodiment, the following effects can be obtained.

  (10) The rotation separation member 41 as the second separation member is configured to be rotatable relative to the third supply pipe 51. Thereby, compressed air comes into contact with the entire peripheral wall of the first member 42, and the action of removing the adhered mist by the clogging preventing means can be exerted on the entire peripheral wall of the first member 42. Moreover, since the rotation separation member 41 is simultaneously cleaned when the apparatus is driven, the frequency of cleaning maintenance can be minimized.

  (11) Within the partition wall 37, a space between the partition wall 37 and the rotation separating member 41 is provided in the front-rear direction, specifically, a partition side wall 39 that partitions the inlet 35 side and the impeller 38 side is provided. Yes. This restricts the mist-containing air sucked from the inlet 35 from being sucked directly into the impeller 38 without passing through the rotary separation member 41. Therefore, the mist-containing air can more reliably pass through the wall surface of the first member 42 of the rotary separation member 41, and the action of removing the mist from the mist-containing air by the rotary separation member 41 can be suitably obtained.

  Each of the above embodiments can be modified and embodied as follows. Further, the following modifications may be combined with each other, and each of the above embodiments may be changed as in the configuration of the combination.

  -In 1st Embodiment, the positional relationship of the 1st chamber A in the casing 1, the 2nd chamber B, and the 3rd chamber C is not limited to the positional relationship of the said embodiment. For example, like the mist removing apparatus of Patent Document 1, a second chamber B is formed on the rear side of the first chamber A, and a cylindrical third so as to surround the motor 12 on the rear side of the second chamber B. Chamber C may be formed.

  In the first embodiment, at least one of the first chamber A and the third chamber C may be omitted, and the first chamber A and the second chamber B, or the second chamber B and the third chamber are connected.

  -In 1st Embodiment, as a 1st separation member arrange | positioned around the impeller 11, it is not necessary that all of the outer peripheral side separation member 13a, the front side separation member 13b, and the rear side separation member 13c are provided. It is sufficient that at least one of the outer peripheral side separating member 13a and the front side separating member 13b is provided. When the outer side separation member 13a is omitted, as shown in FIG. 9, the front side separation member 13b is formed to be slightly larger so that the outer edge of the front side separation member 13b and the inner surface of the peripheral wall 2 of the casing 1 are in contact with each other. It is preferable to configure. Thereby, also when the outer peripheral side separation member 13a is abbreviate | omitted, the collision with the mist containing air discharged | emitted from the impeller 11 and the front side separation member 13b as a 1st separation member can be generated suitably.

-In 1st Embodiment, you may arrange | position the several outer peripheral side separation member 13a in multilayer form. The same applies to the front separating member 13b and the rear separating member 13c.
-In 1st Embodiment, the arrangement number of the 2nd separation member 9 is not specifically limited, It is good also as a structure provided only one. Further, the second separation member 9 may be omitted.

  -In 1st Embodiment, the shape of the 2nd separation member 9 is not limited to the shape of the said embodiment. For example, it may be formed in a bottomed rectangular tube shape, or may be formed in a disk shape or a polygonal plate shape and disposed so as to face the inflow port 5.

  -In 1st Embodiment, the arrangement number of the 3rd separation member 14 is not specifically limited, One piece may be sufficient. Moreover, the shape of the 3rd separation member 14 is not limited to the shape of the said embodiment. For example, the angle of the V-shaped bent portion may be any number of times, or may be an I-shaped section or a W-shaped section instead of the V-shaped section. A plurality of short third separation members 14 may be arranged in the axial direction of the third chamber C.

  On the other hand, in the configuration shown in FIG. 10, the third separation member 14 that extends spirally is disposed in the third chamber C, and the side surface of the third separation member 14 intersects the axial direction of the third chamber C. It has become. In these cases, the same separating action as in the above embodiment can be obtained. When the third separation member 14 is formed in a spiral shape, the rotational direction of the spiral when viewed from the second chamber B side toward the discharge port 6 side is different from the rotational direction of the impeller 11. Thus, the mist-containing air flowing in the third chamber C and the third separation member 14 can be suitably collided.

  Here, “the side surface of the third separation member 14 faces the circumferential direction or the axial direction of the third chamber C” means that the side surface of the third separation member 14 is orthogonal to the circumferential direction or the axial direction. It includes not only the state of being present but all of the states of intersection. That is, only a configuration in which a plate-like member having a circular arc cross section or a cylindrical member is arranged along the circumferential direction and the axial direction of the third chamber C is excluded.

In each of the above embodiments, each separation member is formed by punching metal. However, the material of the separation member is particularly limited as long as it is a member (excluding a fibrous filter) having a predetermined through-hole penetrating the wall surface. Is not to be done. For example, each separation member may be formed of a synthetic resin, or each separation member may be formed of a net such as a wire mesh. In addition, the separation member formed in a plate shape by the net is also included in the technical concept of “first to third separation members made of a plate material having a plurality of through holes” defined in the claims.

  In the first and second embodiments, a heating member such as a heater for heating each separation member may be provided in the casing. In an environment where the temperature is low, such as in winter, the mist (droplet) adhering to each separation member cools and solidifies, and there is a problem that it cannot be discharged while adhering to each separation member. Therefore, by configuring each separation member to be heated by the heating member, solidification of the mist attached to each separation member can be suppressed and the mist can be efficiently discharged.

  In addition, as an installation position of the said heating member in the casing 1, the inner surface of the casing 1, the inner surface or outer surface of the division side wall 7, and the inner surface or outer surface of the division peripheral wall 8 are mentioned, for example in 1st Embodiment. Further, it is possible to embed a heating member inside the partition side wall 7 and the partition peripheral wall 8 and to heat each separation member via the partition side wall 7 and the partition peripheral wall 8.

  -The mist removal apparatus of this invention is applicable also as a dust removal apparatus which removes the dust scattered in the air. In this case, mist supply means for spraying mist on the dust-containing air flowing in from the inlet 5 is further provided. For example, the configuration shown in FIG. 9 includes mist supply means including a mist supply pipe 22 in which the tip nozzle 22 a is located in the first chamber A and a mist supply device 23 connected to the base end of the mist supply pipe 22. ing. In the configuration shown in FIG. 8, a mist supply nozzle 55 is attached to the second shaft body 40 instead of the fourth supply pipe 52, and a mist supply device (not shown) is connected to the second shaft body 40.

  Dust scattered in the air is a very fine and light substance. Therefore, even if the dust-containing air is sucked into the mist removing device and collides with the wall surface of each separation member, the dust is scattered on the air again and flows downstream without being attached to each separation member. Difficult to separate. Here, when the mist is sprayed on the dust-containing air flowing in from the inlet by the mist supply means, the dust in the dust-containing air enters into the fine water droplets constituting the mist, and the dust is captured in the mist. It becomes the state. And when the dust trapped by the mist collides with the wall surface of each separation member in the apparatus, it adheres to the wall surface of each separation member together with the mist and is separated together with the mist from the dust-containing air flowing downstream. Therefore, the dust contained in the dust-containing air can be suitably removed. In addition, when dust containing air has a strange odor, you may spray the mist which mixed the said deodorizing liquid. Moreover, it is good also as a structure which sprays mist using each supply pipe | tube etc. FIG.
