[0033] Specifically, the water mist combines with the waste residue to form water droplets, which fall into the filter plate 10, and the filter plate 10 begins to filter the waste residue. The waste residue is intercepted by the filter plate 10, and the water enters the circulation chamber 403 through the drainage head 405. The waste water can be freely discharged through the control pipe head 406 and the control valve 404. The circulation motor 402 starts to operate, and the water in the circulation chamber 403 is supplemented to the water in the water dividing ring 511 through the circulation pipe 401, so that the water can be recycled, which improves the energy saving of the equipment and improves the functionality of the equipment.

At the same time, the waste discharge pump 504 starts to operate, and the waste gas generated by thermal power generation is input into the heat dissipation pipe 506 through the heat-resistant pipe 509. The heat dissipation pipe 506 and the cold air bin 505 begin to preliminarily cool the hot waste gas. The preliminarily cooled waste gas is input into the processing bin 3 through the waste delivery pipe 502 for processing, so as to prevent overheated waste gas from entering the equipment and damaging the internal waste gas treatment parts, thereby affecting the service life of the equipment and improving the functionality of the equipment);

[0037] Step 2, the atomizing head 518 starts spraying, the stirring motor 520 runs, driving the stirring fan 517 to rotate, and the water mist combines with the exhaust gas entering the processing chamber 3 (the atomizing head 518 and the cleaning wall head 514 start to spray water mist into the processing chamber 3, and the water mist combines with the waste residue in the exhaust gas. The stirring motor 520 starts to run, and the stirring rod 519 drives the stirring fan 517 to start rotating, which assists the water mist and the waste residue in the exhaust gas to fully merge, thereby improving the quality of the equipment to treat the exhaust gas. The water frame 515 can clean the inner wall of the processing chamber 3 to prevent the waste residue from accumulating in the processing chamber 3. The equipment can automatically self-clean, thereby improving the functionality of the equipment and reducing the workload of the staff. The mist can be intercepted by the mist blocking plate 9 to prevent the leakage of harmful mist and pollution to the environment, and the treated exhaust gas is discharged through the processing chamber 3);

[0038] Step three, the combined water droplets fall into the filter plate 10, and the water passing through the filter plate 10 will enter the circulation bin 403 along the drainage head 405, and will be recycled through the circulation pipe 401 (the water mist combines with the waste residue to form water droplets, which fall into the filter plate 10, and the filter plate 10 begins to filter the waste residue. The waste residue is intercepted by the filter plate 10, and the water enters the circulation bin 403 through the drainage head 405. The waste water can be discharged freely through the control pipe head 406 and the control valve 404, and the circulation motor 402 starts to operate, and the water in the circulation bin 403 is supplemented to the water in the water diversion ring 511 through the circulation pipe 401, so that the water can be recycled, which improves the energy saving of the equipment and improves the functionality of the equipment).
