During the use, air-blower 38 lets in the dust removal box 2 with waste gas through intake pipe 13 in, motor 35 rotates and drives the reciprocal lead screw 7 rotation of dust removal through belt pulley 36 and driving belt 37, the reciprocal lead screw 7 rotation of dust removal drives piston 5 reciprocating motion, under the effect of two check valves 6, water in the piston 5 drive dust removal box 2 passes through filter tube 3, after the filtration of filter element 4, get back to in the dust removal box 2 again, thereby it is absorbing the back to the dust of waste gas to drive the water in the dust removal box 2, the rethread filters and collects the dust in the aquatic in filtering element 4, can avoid water to absorb the decline of the ability that leads to adsorbing the dust after more dust.

Waste gas is in the absorption liquid that lets in the absorption box 8 bottom through letting in pipe 9 after the dust removal, motor 35 rotates and drives reciprocal lead screw 10 of lift and rotate, under the effect of gag lever post 12, reciprocal lead screw 10 of lift rotates and drives lift box 11 and carry out vertical reciprocating motion, lift box 11 removes and risees the absorption liquid in the lift box 11, and spill through the watering hole, can increase the area of contact of waste gas and absorption liquid, extension contact time, can fully absorb the harmful gas in the waste gas.

Finally, it should be noted that: although the present invention has been described in detail with reference to the foregoing embodiments, it will be apparent to those skilled in the art that modifications may be made to the embodiments or portions thereof without departing from the spirit and scope of the invention.
