When the cleaning assembly starts to work, the plurality of brush plates 25 will rotate or vibrate under the drive of the transmission assembly. This movement causes the bristles of the brush plates 25 to move relative to the inner wall of the net tube 22, thereby scraping and cleaning away impurities and dirt attached thereto.

[0033] In this embodiment, the air extraction component includes: An air pump box 7, which is arranged on the outer side wall of the treatment tower 1, and an air pump is arranged in the air pump box 7; An air intake pipe 8, which is arranged on the output port of the air pump; Valve 11, valve 11 is arranged on the input port of the air pump; The tube body 10 has one end connected to the valve 11 and the other end connected to the input pipe 9 .

[0034] When the system needs to start the vacuum function, first ensure that valve 11 is in the open state, allowing gas to enter the air pump through the tube body 10. After the air pump is started, negative pressure or positive pressure is generated through its internal mechanical structure, sucking gas from the input pipe 9 and discharging it to the required position through the air inlet pipe 8. During the whole process, the valve 11 can adjust the opening as needed to control the speed and amount of gas entering the air pump. After the processing is completed, close the valve 11 and the air pump to cut off the gas flow and stop working.

[0035] In this embodiment, the air extraction component further includes: A plurality of first baffles 20 are fixed on the outer side wall of the rotating shaft 19 at equal distances, and the plurality of first baffles 20 are all located above the partition 18 .

[0037] When the external liquid supply system is started, the liquid to be sprayed enters the annular tube 12 through the feed pipe 3. In the annular tube 12, the liquid is evenly distributed to each spray head 13. The spray head 13 sprays the liquid into the inner space of the treatment tower 1 in the form of fine droplets to form a uniform liquid film or gas-liquid mixture. In this way, the waste gas, waste water or reactant can fully contact with the spray liquid and undergo physical, chemical or biological reactions, thereby achieving the purpose of treatment.

[0038] In this embodiment, the spray assembly further includes: A plurality of second baffles 26 are arranged at equal distances on the outer side wall of the rotating shaft 19 , and each second baffle 26 is located in the net cylinder 22 .

[0039] In this embodiment, the spray assembly further includes: The motor 29 is arranged at the bottom of the processing tower 1, and the output shaft of the motor 29 is fixed to the rotating shaft 19.

[0040] In this embodiment, the spray assembly further includes: An output pipe 2, which is arranged on the top outer wall of the treatment tower 1; Heat exchange tube 21, heat exchange tube 21 is arranged in treatment tower 1, and heat exchange tube 21 is outside mesh tube 22, both ends of heat exchange tube 21 are provided with connecting tube 4, and two connecting tubes 4 are penetrated through the outer wall of treatment tower 1; The sewage pipe 5 is penetrated and arranged on the outer wall of the treatment tower 1 . A sealing cover 6 is arranged at the end of the sewage pipe 5 . One end of the sewage pipe 5 penetrates the top of the partition 18 .

[0041] Example 2 The present invention provides a method for controlling pollutant emissions from power generation by burning coal sludge, comprising: The waste gas output from the coal slime incineration equipment is input into the pollutant treatment device; The pollutant treatment device performs dust filtration on the input exhaust gas to ensure that the dust content in the exhaust gas meets the standard, and at the same time concentrates the dust for unified treatment of the dust; Testing equipment, which is used to test the exhaust gas; Finally, by recording and analyzing the output values ​​of the detection equipment, it is determined that the emitted gas meets the standards.

[0042] In this embodiment, the specific working method is: when in use, when the waste gas output by the coal slime incineration equipment enters the mesh tube 22 in the treatment tower 1 through the input pipe 9, the gas is output through the mesh holes on the mesh tube 22, the dust is filtered, and the two ends of the connecting pipe 4 are connected to the water circulation equipment. In this process, the heat in the waste gas is absorbed by the water in the heat exchange pipe 21, so as to realize the recovery of the heat in the waste gas; The waste gas then enters the space above the partition 18 through the connecting pipe 15, connects the treatment liquid and the feed pipe 3, and the treatment liquid enters the annular pipe 12 through the feed pipe 3, and then outputs through the spray head 13 to achieve the treatment of the waste gas. The "η" structure of the connecting pipe 15 prevents the liquid from entering the space below the partition 18; During the treatment process, the switch of the motor 29 is turned on, and the motor 29 drives the rotating shaft 19 to rotate. During the rotation of the rotating shaft 19, the second baffle 26 is driven to rotate, so that the gas inside the net cylinder 22 is in a spiral state, so that the dust with heavier weight is thrown to the inner wall of the net cylinder 22, thereby increasing the separation effect of the net cylinder 22; After the exhaust gas work is completed, the driving motor 29 rotates in the opposite direction. At this time, under the blocking effect of the limiting plate 28, the rotating shaft 19 drives the connecting frame 24 to rotate through the L-shaped rod 27, and then drives the annular plate 23 to rotate, so that the brush plate 25 on the annular plate 23 can move along the inner wall of the mesh tube 22 to clean the dust in the mesh tube 22. At the same time, the valve 11 and the air pump switch are turned on, and the air pump works to input the gas containing a large amount of dust inside the mesh tube 22 into the annular seat 16 through the input pipe 9, the tube body 10 and the air intake pipe 8, and output it through the through hole 17 on the annular seat 16, and cooperate with the first baffle 20 on the rotating shaft 19 to make the exhaust gas and the water above the partition 18 fully mixed, so that the dust remains in the treatment liquid to achieve dust treatment, and finally open the sealing cover 6 to output the treatment liquid containing dust and harmful substances through the sewage pipe 5.

[0043] The above shows and describes the basic principles and main features of the present invention and the advantages of the present invention. It is obvious to those skilled in the art that the present invention is not limited to the details of the above exemplary embodiments, and the present invention can be implemented in other specific forms without departing from the spirit or basic features of the present invention.
