[0030] A support frame 111 is fixedly installed on the inner wall of the middle part of the intake pipe 101. A heat conduction pipe 112 is fixedly installed inside the support frame 111. Both ends of the heat conduction pipe 112 penetrate above the intake pipe 101, and connecting heads 113 are fixedly installed at both ends of the heat conduction pipe 112, as Figure 3 shown, if the temperature of the chemical gas is relatively high, heat conduction fluid can be introduced into the heat conduction pipe 112 to cool and recycle the high temperature of the chemical gas;

[0031] The treatment mechanism 2 includes a treatment box 201. A diversion slope 202 is fixedly installed at the bottom of the inner wall of the treatment box 201. The lower end of the side of the treatment box 201 is fixedly installed with the intake pipe 101.

[0034] The working principle of the present utility model:

[0035] When the device is in use, chemical gas is introduced into the intake pipe 101. The particulate impurities in the chemical gas are intercepted by the filter screen 106. When some impurities adhere to the surface of the filter screen 106 and cause blockage, the electric cylinder 107 is started to contract, and the movable rod 109 is driven to move into the intake pipe 101 through the connecting piece 108. Thus, the scraping block 110 scrapes on the surface of the filter screen 106, and the impurities accumulated on the surface of the scraping block 110 fall onto the surface of the collecting plate 104;

[0036] Secondly, the filtered chemical gas enters the treatment box 201. The air flow is made uniform through the evenly distributed holes 205, and the instability of the gas flow is reduced. The washing liquid is input into the annular pipe 208 and flows into the lower ends of the respective infusion pipes 209. Finally, the washing liquid is output from the lower end of the nozzle 210. Part of the washing liquid sputters on the surface of the upper sputtering plate 212 and spreads outwards, and the other part falls onto the surface of the lower sputtering plate 214 through the through port 213 and is sprayed downwards through the water outlet holes 215, thereby assisting the washing liquid to fully contact the pollutants in the chemical gas. The purified chemical gas is discharged upwards through the collecting pipe 207.

[0037] The above has described in detail an embodiment of the present utility model, but the content described above is only a preferred embodiment of the present utility model and cannot be considered as defining the scope of implementation of the present utility model. All equivalent changes and improvements made in accordance with the scope of application of the present utility model shall still fall within the scope covered by the patent of the present utility model.
