Further, the metallic matrix of stainless steel cloth demister is compounded with PTFE thin layer.
Compared with prior art, beneficial effect of the present invention is:
1, inner tank wall arranges baffling box, the face of the baffling box relative with air inlet pipe is inclined plane, the natural gas arriving baffling box inclined plane is changed the flow direction by baffling box completely, natural gas is discharged from the steam vent of baffling box and is entered tank body along inner tank wall tangential direction and does gyration, solid particle in natural gas and larger free liquid are dripped and are clashed into inner tank wall under the influence of centrifugal force, and to drop on spiral board along inwall and finally fall into collecting tank, the centrifugation clean-up effect of natural gas is improved greatly.
2, the first baffle plate in tank body and second baffle, and separator tube is provided with between two plates, spiral board is provided with between separator tube and tank body, spiral board forms helical gas channel between the external cylindrical surface and the inwall of tank body of separator tube, when natural gas rotates in helical gas channel under the influence of centrifugal force, fraction solids particle and droplet fall into collecting tank from drop hole, reach the object of gas-liquid separation.
3, stainless steel cloth demister is set in body, after natural gas enters washing tank, the free drop that particle is large and solid particle fall into washing tank collecting tank, natural gas rises to fine and close stainless steel cloth, less solid particle is blocked, small drop is built up and also finally fall into collecting tank in stainless steel cloth demister, and the natural gas after purification is discharged from escape pipe, and Compressed Gas is effectively purified.
4, on the base material of stainless steel cloth demister, be compounded with PTFE thin layer, due to low friction and the antistick characteristic of PTFE film, the frictional resistance between droplet and demister can be reduced, greatly improve washing tank purification efficiency.

Detailed description of the invention
Below in conjunction with accompanying drawing, the present invention will be further described:
As shown in the figure, a kind of cyclone type natural gas washing tank, comprises tank body 1, the air inlet pipe 2 be connected with tank body 1 and escape pipe 3.Baffling box 4 is connected with, in the mouth of pipe of air inlet pipe 2 is enclosed in by baffling box 4 in tank body 1.Wherein, air inlet pipe 2 one end to be stretched in tank body 1 and is connected and fixed with tank body 1, and baffling box 4 is connected with tank body 1 inwall, and in the mouth of pipe of air inlet pipe 2 is enclosed in; Also air inlet pipe 2 can be set with in baffling box 4, baffling box 4 is positioned at tank body 1 and is connected with tank body 1.Above-mentioned connected mode directly can adopt and be welded to connect, and also can adopt and be threaded.The face of the baffling box 4 relative with air inlet pipe 2 is inclined plane 41, and make the length of baffling box 4 two sides different, baffling box 4 is provided with exhaust outlet 42, and wherein exhaust outlet 42 is arranged on the longer side of baffling box 4 length.Be provided with the first plate washer 7 being positioned at tank body 1 above baffling box 4, be provided with the second plate washer 8, first plate washer 7 center being positioned at tank body 1 below baffling box 4 and be provided with venthole 12, second baffle 8 is provided with drop hole 13.Be provided with separator tube 9 between first plate washer 7 and the second plate washer 8, bottom separator tube 9, be provided with venthole 10.Be provided with spiral board 11 between separator tube 9 and tank body 1, spiral board 11 forms helical gas channel between the external cylindrical surface and the inwall of tank body 1 of separator tube 9.Be provided with above first plate washer 7 be positioned at tank body 1 stainless steel cloth demister 5, second plate washer 8 below be provided with the collecting tank 6 being positioned at tank body 1.
The metallic matrix of stainless steel cloth demister 5 is compounded with PTFE thin layer, PTFE is a kind of material with corrosion-resistant, low friction, antistick characteristic, stainless steel wire is wrapped in PTFE completely as base material, stainless steel wire surface forms the wear-resisting resistance to PTFE thin layer drawn of one deck, the not viscosity on overall silk screen surface, self-cleaning and corrosion resistance can be kept, the droplet simultaneously with superelevation catches performance, and the filter efficiency of whole demister is greatly improved.Stainless steel cloth wherein in stainless steel cloth demister 5 is set to two-layer, and the aperture of stainless steel cloth is irregularly shaped.
When the present invention works, natural gas enters baffling box from air inlet pipe, and the natural gas entered in baffling box is changed the flow direction by the inclined plane of baffling box completely, and carries out one-level separation to natural gas; Discharge from the steam vent of baffling box and enter tank body along inner tank wall tangential direction afterwards and do gyration, by centrifugal action, the second-order separation is carried out to natural gas; After natural gas enters washing tank, the free drop that particle is large and solid particle fall on spiral board and also finally fall into collecting tank, and natural gas enters by spiral board, the helical gas channel that formed between separator tube and tank body, and when rotating in gas passage road under the influence of centrifugal force, fraction solids particle and droplet fall into collecting tank from drop hole, and natural gas carries out three grades of separation by collision, eddy flow; Natural gas out rises to fine and close stainless steel cloth demister by venthole, venthole in helical gas channel, less solid particle is blocked, small drop to be built up in stainless steel cloth demister and is finally fallen into collecting tank, stainless steel wire demister by catching mist, adhesion, cohesion carry out level Four separation to natural gas; Natural gas after purification is discharged from escape pipe, and natural gas is effectively purified.
