Description
Technical field
The present invention relates to a kind of multiphase flow filter separator, belong to gas and oil separating plant technical field.
Background technology
, it is necessary to be removed using a variety of filtering separation devices in natural gas in natural gas surface gathering and transferring and decontamination process
Solid and liquid impurity, to ensure makings and collect defeated safety.Conventional filtering separation device has gravity separator, centrifugation or rotation
Wind separator, coalescing filter etc..Because gas on-site operating mode is unstable, to ensure separating property, a kind of filtering can not be leaned on
Separation equipment removes the solid phase and liquid phase impurity of gas, but uses two or more filtering separation device combination to make
With for example with the combination of cyclone separator and coalescing filter.
Three kinds of principles that solid phase and liquid phase impurity are isolated from gas are momentum mechanics, gravitational settling and coalescence respectively,
Any kind filtering separation device can all use one or more of above-mentioned three kinds of principles.By the fortune for changing gas and impurity
Dynamic direction, such as centrifugation or cyclonic separation, can be achieved the separation of large granular impurity；Gravity is to complete to separate most important power, is passed through
Impurity sedimentation completes separation；Fine drop（Such as spray）It is difficult to lean on Gravity Separation, coalesce droplet using coalescence principle
Into big drop, and then realize gas-liquid separation.
At present, filtering separation device is directly entered filtering separation device inner chamber from inlet ductwork using natural gas more and implements to divide
From mode of operation.Patent No. ZL200920222609.8（Publication No. CN201055811Y）Chinese utility model patent
《A kind of integrated gravity separator》, disclose a kind of including cylinder, the L-type air inlet pipe being arranged on cylinder and gas outlet
Integrated gravity separator.Cylinder is divided into the first chamber being connected with gas outlet and the second chamber being connected with air inlet pipe,
It is provided with two chambers and is separated by filtration filter core.The mouth of pipe of described L-type air inlet pipe is separated by filtration filter core backwards, towards in cylinder
Wall, impingement baffle is provided with the cylinder inboard wall of mouth of pipe face so that pass through containing miscellaneous gas and slow down suddenly after L-type air inlet pipe and air-flow
Direction changes, and under inertia, centrifugal force and gravity comprehensive function, realizes that gas and impurity just separate.The shortcomings that technology is：It is real
In the operation of border, containing miscellaneous gas in L-type air inlet pipe flow at high speed, to slow down suddenly when impacting impingement baffle, energy loss is larger, and the
One chamber forms the turbulent area of complexity, is unfavorable for the separation of impurity.The design of impingement baffle is actual equivalent to traditional separator
Inlet baffle formula current divider, pre-separation effect are poor.
The content of the invention
The present invention overcomes the problems such as uneven Flow Field Distribution existing for existing separation equipment, pre-separation effect difference, there is provided a kind of
Add the multiphase flow filter separator of guiding device.
The present invention is made up of cylinder, air inlet pipe, conduit, filter core, escape pipe, upper blow-off pipe and down blow pipe, on conduit
Guiding device is provided with by flange.
The present invention can improve Flow Field Distribution of the gas inside filtering separation device, make gas even into being separated by filtration
With filter core, mitigation of gases flow velocity, impact of effective buffer gas to filtering separation device cylinder inboard wall, momentum and gravity are utilized
Principle is settled, realizes impurity（Especially liquid phase thing）Pre-separation, effectively improve the separative efficiency of solid, liquid phase impurity.

Embodiment
The present invention is described in detail below in conjunction with the accompanying drawings：
Referring to Fig. 1, the present invention is by cylinder 6, air inlet pipe 1, conduit 2, filter core 4, escape pipe 5, upper blow-off pipe 7 and down blow pipe
8 compositions, guiding device 3 is provided with conduit 2 by flange.
Referring to Fig. 2, Fig. 3, described guiding device 3 is made up of bottom 3a, guide vane 3b and top cover 3c, and bottom 3a is loudspeaker
Mouth shape, it is connected by flange with conduit 2；Bottom 3a imports internal diameter is identical with the internal diameter of conduit 2, and exit inside diameter is the internal diameter of cylinder 6
1/3 to 1/2.
Top cover 3c is concave shape, and the gas for rotating upward cross-sectional area and gradually increasing is formed with bottom 3a and guide vane 3b
Body passage, to ensure that gas flowing is smooth, and formed and rotate up air-flow with certain inclination angle.
Referring to Fig. 3, Fig. 4, described guide vane 3b is arcuation, between bottom 3a and top cover 3c, circumferentially array.
Its flexibility is：Intersection point in guide vane 3b outer rims projection line Yu bottom 3a lower surfaces is P, guide vane 3b outer rim projection lines
Tangent line, the straight line angulation α with crossing intersection point P and bottom 3a and top cover the 3c center of circle is 20 ° to 60 °；In guide vane
3b outer rims projection line and top cover 3c intersection point be Q, the tangent line of guide vane 3b outer rim projection lines, with mistake intersection point Q and bottom 3a
Straight line angulation β with the top cover 3c center of circle is 60 ° to 90 °.
The operation principle of the present invention is as follows：Gas enters guiding device 3 by air inlet pipe 1, conduit 2, by guiding device 3 by gas
Body enters in filter separator cylinder 6 after forming eddy flow.It is transversal due to gas passage when gas flows through 3 inside of guiding device
Area gradually increases with airflow direction, and gas flow rate reduces, flow direction changes, and a part is entrained in the impurity in gas
By retardation, there is the loss of momentum.In the exit of guiding device 3, the larger impurity of the loss of momentum is under gravity, first
First it is settled down to filtering separation device bottom；The less impurity of the loss of momentum is then thrown on the inwall of filter separator cylinder 6,
The inwall of cylinder 6 is assembled, and flow to filter separator bottom under gravity, bottom liquid phases are discharged via down blow pipe 8.More granule
The impurity of degree then enters 4 further coarse separation of filter separator filter core with gas.Most of impurity is in the bottom rich stream of filter core 4
Discharged to filter separator bottom；On a small quantity impurity is penetrated to discharge in upper blow-off pipe 7.Clean gas after separation is then by escape pipe 5
Discharge.
Three kinds of the filter separator comprehensive momentum mechanics, gravitational settling and coalescence separate modes, there is preferably separation to imitate
Fruit, applicable condition range is wider, the big operating mode of the liquid content that is particularly suitable for use in.
Application examples：Referring to Fig. 5, the particle that certain density median is 18 μm is added in inlet gas, test is not
With point under gas velocity, not installing any gravity separator for being separated by filtration element and the gravity separator for being only provided with diversion component additional
From efficiency.As a result show, after installing the device additional, separative efficiency of the filtering separation device to the impurity of more than 15 to 20 microns of particle diameter
More than 70%, reduce the live load of other separating components filtering separation device Nei, extend filter core service life, reduce
Operating cost.
