The working principle is as follows: during the use, the interpolation has the spraying liquid that adsorbs the purification effect to waste gas in the box, waste gas that the dirty fermentation cylinder of excrement produced gets into the air inlet chamber 8 of pivot 5 from intake pipe 10 through rotary joint 9 in, then get into the air outlet chamber 12 of each puddler 11, again from the venthole 14 blowout of outlet duct 13 get into in the spraying liquid of box 1 bottom, spraying liquid carries out primary purification to waste gas, then waste gas rises, the spraying liquid of box 1 bottom is then taken out to spray pipe 3 and spout from the shower nozzle by circulating pump 7, carry out secondary purification to the waste gas that rises, waste gas after the purification is discharged from the blast pipe 2 at top.

When waste gas enters the box body 1, the driving mechanism drives the rotating shaft 5 to rotate, and the arrangement can enable the stirring rod 11 to stir the spraying liquid in the box body 1, promote the flowing of the spraying liquid, improve the distribution uniformity of effective components in the spraying liquid, enable the spraying liquid to be fully contacted with the waste gas and improve the waste gas treatment effect; on the other hand, the exhaust gas can be made to have a rotational speed when being ejected from the outlet holes 14, and the rising path of the exhaust gas in the shower liquid is extended, and the contact time between the exhaust gas and the adsorbent is extended. In addition, after the waste gas enters the box body, a plurality of strands of rotary air flows are formed and dispersed in the spraying liquid in the box body under the combined action of the rotating shaft, the stirring rod and the air outlet pipe, the contact area of the waste gas and the spraying liquid can be increased, and the waste gas treatment effect is improved.

The packing layer 4 can increase the contact area of the waste gas and the spraying liquid during the second purification treatment, so that the waste gas is fully purified by the spraying liquid sprayed from the spray head.

After the waste gas enters the gas outlet pipe 13, the waste gas passes through the gap between the adjacent blades when passing through the rotating ring 20, and drives the rotating ring 20 to rotate, and the rotating ring re-distributes the gas to the waste gas, so that the waste gas is uniformly discharged from each gas outlet hole 14 on the gas outlet pipe 13, and the dispersity of the waste gas is improved.

A piston 15 is arranged in the air outlet pipe 13, when waste gas is not introduced into the rotating shaft 5, the plug 16 is positioned at the joint of the communicating part and the air outlet part under the action of the spring 19 and separates the communicating part and the air outlet part, and the piston 15 plugs the air outlet hole 14 at the moment, so that the spraying liquid in the box body 1 can be prevented from entering the air outlet pipe 13; when the waste gas enters the gas outlet pipe 13, the waste gas flow generates thrust on the piston 15, so that the piston 15 moves and the gas outlet hole is opened, the plug 16 moves along with the piston and is separated from the communicating part, and the communicating part is communicated with the gas outlet part, so that the waste gas is discharged from the gas outlet hole 14.

Having described embodiments of the present invention, the foregoing description is intended to be exemplary, not exhaustive, and not limited to the disclosed embodiments.
