Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a device for removing dust, dust, oil mist, smoke exhaust, etc. (hereinafter referred to as "dust / smoke") discharged from a crusher.

[0002]

[Prior art]

 BACKGROUND ART Conventionally, in order to reuse metal scrap such as city iron scrap, scrapped vehicles, and cutting scraps, it has been practiced to put metal scrap into shredders into strips. It is inevitable that impurities such as dust, dust, and oil mist will be mixed and adhered to the crushed pieces. In order to reuse the debris, it is necessary to remove these debris from the debris.

[0003]

[Problems to be solved by the device]

 In the past, these wastes were separated and removed, but the actual situation is that the wastes are not sufficiently removed and are directly discharged to the outside air from the discharge tower, which causes pollution due to air pollution. There was a problem. In particular, a large amount of water-soluble cutting oil adhered to the metal scraps, etc., causing a large amount of oil mist, etc. and smoke emission, leading to air pollution.

An object of the present invention is to suppress the discharge of dust and smoke from a crusher and prevent air pollution.

[0005]

[Means for Solving the Problems]

 In the device for removing dust and flue gas according to the present invention, as shown in FIG. 1, a first separating device 2 connected to a crusher 1 by a duct 5, a first separating device 2 and ducts 5a, 5b. It is equipped with a second separating device 3 connected through a blower and a blower 4 for feeding dust and flue gas from the crusher to the first separating device 2 and the second separating device 3. is there.

[0006]

[Action]

 By driving the blower 4, the dust / smoke is fed from the crusher 1 to the first separating device 2 via the duct 5, and further to the second separating device 3 via the ducts 5a and 5b. It is separated and removed in the process.

[0007]

【Example】

 An embodiment of the present invention will be described below with reference to FIG. The dust and smoke generated in the crusher 1 are scrubber 2 which is the first separating device and oil mist which is the second separating device and smoke removal through the ducts 5, 5a and 5b by the suction force of the blower 4. Each is processed by the device 3.

The scrubber 2 is connected to the crusher 1 by a duct 5. In the scrubber 2, dust and smoke that have entered the scrubber are collided with water by the illuminator 21 and agitated, and dust and smoke in the gas are separated into water in the tank 22. Dust and smoke that could not be collected by the scrubber 2 are collected by a mist separator 23 provided at the outlet of the scrubber 2 for water in gas and oil mist. The scrubber 2 is connected to the blower 4 by the duct 5a, and the damper 6 is provided in the duct 5a, and the damper adjusts the suction amount of the blower. The blower 4 is connected to the oil mist and the smoke removing device 3 by a duct 5b. Dust and smoke emitted from the scrubber 2 reach the oil mist and the smoke removing device 3 through the ducts 5a and 5b.

In the oil mist and smoke removing device 3, a punching plate 31 is provided on the inlet side (left side in the figure) as a rectifying means, and a first filter 32, a second filter 33 and a third filter 34 are provided adjacent to the punching plate 31 toward the outlet side. They are arranged sequentially. Reference numeral 35 is an inspection port.

Regarding the dust and smoke, the solid content (dust) is collected by the first filter 32, the moisture and oil mist are collected by the second filter 33, and finally the smoke is collected by the third filter 34. Gathered.

Clean air is generated by the oil mist and the smoke removing device 3, and is discharged to the outside air by the discharge tower 7. At this time, the noise reduction device 8 is used to prevent noise.

[0012]

[Effect of device]

 According to this invention, the dust and smoke from the crusher are separated by the first and second separating devices and discharged to the outside air, so that the problem of air pollution can be solved.
