The filter screen 2 blocks and filters the soot particles in the flue gas, and the filtered flue gas is discharged from the smoke outlet holes 21; A plurality of dust outlets 13 are arranged at the bottom of the tank body 1, and the dust outlets 13 are evenly distributed around the smoke inlet 11. The dust outlets 13 are located between the smoke inlet 11 and the filter screen 2. The filtered dust particles fall into the dust outlets 13 under the action of gravity; A desulfurization layer 5 is arranged inside the dust outlets 13, and the particles are desulfurized through the desulfurization layer 5 inside the dust outlets 13.

[0025] A fixed ring 41 is arranged at the top of the booster platform 4, a fixed seat 43 is arranged inside the fixed ring 41, a plurality of connecting blocks 42 are evenly arranged outside the fixed seat 43, the other ends of the connecting blocks 42 are connected to the inner wall of the fixed ring 41, and the height of the connecting blocks 42 is the same as the height of the fixed ring 41.

[0026] Specifically, the fixing base 43 is fixed inside the fixing ring 41 through the connecting block 42, and the flue gas enters the filter screen 2 through the gap between the fixing base 43 and the fixing ring 41.

[0027] A second bearing 44 is arranged inside the fixing base 43. The top surface of the second bearing 44 is flush with the top surface of the fixing base 43. A balance shaft 32 is arranged inside the second bearing 44, and a gas turbine 3 is arranged at the other end of the balance shaft 32. Above the tank body 1, a motor 14 is arranged, and a driving shaft 31 is arranged at the bottom of the motor 14. The driving shaft 31 is connected to the top surface of the gas turbine 3.

[0028] Specifically, the balance shaft 32 can rotate independently of the fixing base 43 through the second bearing 44; the motor 14 drives the driving shaft 31 to drive the gas turbine 3 and the balance shaft 32 to rotate.

The motor 14 is started, driving the gas turbine 3 to rotate inside the filter screen 2, driving the flue gas to rotate. The dust particles in the flue gas are blocked on the inner wall of the filter screen 2. The rotation of the gas turbine 3 forms a pressure difference inside the tank body 1, and the filtered flue gas is pumped outwards from the smoke outlet hole 21 and discharged from the smoke exhaust port 12; the dust particles blocked in the filter screen 2 finally fall out from the dust outlet 13 under the action of gravity and are desulfurized by the desulfurization layer 5 in the dust outlet 13.
