[0037] 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.
