A number of atomizing nozzles 14 are arranged on both the second spray pipe 11 and the third spray pipe 12.

[0027] Through the setting of the pressure pump 13, the water sprayed by the atomizing nozzles 14 is high-molecular-density water mist, and this water mist can effectively remove impurities and toxic and harmful substances in the water.

[0028] Furthermore, a second filter basket 15 is provided at the bottom in the second treatment chamber, and the centrifugal separation device is located above the second filter basket 15. The centrifugal separation device includes a driving motor 16 and a separation chamber 17. The driving motor 16 is fixedly installed on the top of the dust removal box body 1.

The large particles and soot in the gas fall into the first filter basket 5 after contacting with water, and the sewage is discharged through the first sewage discharge pipe 6. The gas is subjected to primary treatment in the first treatment chamber. The treated gas is pumped into the second treatment chamber under the action of the circulating impeller 21. The gas enters the upper part of the second treatment chamber and moves from top to bottom. During this process, it contacts with the high-molecular-density water mist, which can remove the remaining impurities and harmful substances in the gas. The clean gas is discharged into the atmosphere through the exhaust pipe 4. The impurities and harmful substances fall into the separation chamber 17 after contacting with the high-molecular-density water mist. Under the rotation of the separation chamber 17, the water is thrown out, and the impurities and harmful substances leave from the bottom end of the conical shell along the guide flow 22 and fall into the second filter basket 15. The sewage in the second treatment chamber is discharged through the second sewage discharge pipe 20.

[0033] The first filter basket 5 and the second filter basket 15 can collect the filtered sundries, effectively reducing the labor intensity of the staff.
