At the same time, the filter screen is cleaned to prevent the filter screen from being blocked, thereby ensuring that the waste gas treatment device for producing sludge backfill agent can be used normally.

3. The waste gas treatment device for producing sludge backfilling agent is provided with an adsorption and capturing mechanism, which captures particulate matter in the waste gas, and filters the particulate matter in the waste gas in the second treatment chamber through the negative pressure generated by the reflux pipe and the adsorption and capturing mechanism, while preventing the accumulation of excessive particulate matter at the reflux pipe opening, causing blockage, thereby ensuring that the waste gas treatment device for producing sludge backfilling agent can be used normally.

4. The waste gas treatment device for producing sludge backfilling agent is provided with a treatment chamber 1 and a treatment chamber 2. The exhaust gas is decelerated and diverted through the shape design of the treatment chamber 1 and the treatment chamber 2. The exhaust gas is filtered more fully during the filtering process.

The working principle of this embodiment is as follows: when the waste gas treatment device for producing sludge backfilling agent is used, the waste gas is introduced into the processing chamber 1 402 through the air inlet pipe 2, and the gas is pressurized and filtered through the pressurization and filtering mechanism 41 in the processing chamber 1 402. The gas passes through the power fan 416, so that the power fan 416 rotates to drive the central shaft 1 411 to rotate. At the same time, the sealing ring 1 413 on the pressure relief block 412 inside the processing chamber 1 402 increases the internal pressure of the processing chamber 1 402, and the pressure relief block 412 is pushed upward to make the pressure relief hole 418 connected with the processing chamber 2 401, so that the gas passes through the filter screen 1 404 and flows into the processing chamber 2 401 for pressure relief. After the pressure relief, the spring 1 415 squeezes the limit ring 414 to reset the pressure relief block 412, and the waste gas flowing into the processing chamber 2 401 is because of the processing chamber 1 413. 02 has a relatively high pressure and a relatively fast flow rate, so that the exhaust gas flowing into the processing chamber 2 401 flows back to the processing chamber 1 402 through the reflux pipe 403 for secondary filtration. The one-way valve 406 arranged on the reflux pipe 403 prevents the exhaust gas from flowing back. The particulate matter inside the processing chamber 1 402 is collected by the adsorption and cleaning mechanism 42. At the same time, the airflow generated by the pressure relief of the filter net 1 404 adsorbs the particles at the bottom, and the processing chamber 2 401 is adsorbed and collected by the adsorption and capturing mechanism 43. The adsorption and capturing mechanism 43 adsorbs and collects the particulate matter by cooperating with the reflux hole 1 405. When the pressure in the processing chamber 2 401 is relatively high, the pressure is relieved through the pressure relief block 412 arranged on the top of the central axis 1 411, and the gas is filtered through the filter net 1 404, and the filtered gas flows into the exhaust port 3.
