The specific embodiment
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 being connected with tank body 1 and escape pipe 3.In tank body 1, be connected with baffling box 4, in baffling box 4 is enclosed in the mouth of pipe of air inlet pipe 2.Wherein, air inlet pipe 2 one end are stretched in tank body 1 and are 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 can be by air inlet pipe 2 suits and baffling box 4, baffling box 4 is positioned at tank body 1 and is connected with tank body 1.Above-mentioned connected mode can directly 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, makes the length of baffling box 4 two sides different, and baffling box 4 is provided with exhaust outlet 42, and wherein exhaust outlet 42 is arranged on the side that baffling box 4 length are longer.Baffling box 4 tops are provided with the first plate washer 7 that is positioned at tank body 1, and baffling box 4 belows are provided with the second plate washer 8, the first plate washer 7 centers that are positioned at tank body 1 and are provided with venthole
