[0047] Working principle:

[0048] When in use, the desulfurizing agent solution is introduced into the processing box 1 through the feed port 8, and the introduced desulfurizing agent solution overflows the stirring blade 16 and is located below the filter plate 19. The coolant is introduced into the condenser 26 through the water inlet 6, the temperature of the condenser 26 will decrease, and the coolant in the condenser 26 will be discharged through the water outlet 7. The heating plate 20 is powered on, and the temperature of the heating plate 20 increases.

[0049] When the smoke to be de-bleached is introduced into the air inlet 3, the smoke will impact the fan blades 15, causing the fan blades 15 and the third rotating shaft 14 to rotate. The third rotating shaft 14 will drive the first bevel gear 29 to rotate, driving the second bevel gear 30 to rotate.

[0050] The second bevel gear 30 drives the first rotating shaft 12, the second rotating shaft 13, and the fifth rotating shaft 33 to rotate, which in turn causes the third bevel gear 31 to rotate, driving the fourth bevel gear 32 to rotate, causing the fourth rotating shaft 18 to rotate, driving the stirring blade 16 to rotate.

[0051] The fan blades 15 have a buffering effect on the flue gas, and then the flue gas will contact the condenser 26. The condenser 26 will cool the high-temperature flue gas, so that the water molecules in the flue gas condense and contact the dust in the flue gas, and the dust is knocked off by the water molecules, thereby playing a dust removal role.

[0052] The flue gas after dust removal by the condenser 26 will enter the diversion box 4, then enter different connecting pipes 21, and then be discharged into the desulfurizer solution through the through hole 28. The flue gas reacts with the desulfurizer solution. During the reaction, the stirring blade 16 stirs the desulfurizer solution, so that the flue gas contacts with more desulfurizer solution, and the flue gas can react with the desulfurizer solution more fully, thereby improving the treatment efficiency of the flue gas.

[0053] The flue gas after reacting with the desulfurizing agent solution passes through the filter plate 19 and enters the heating plate 20, where the flue gas is heated to reach the standard discharge temperature. The heated flue gas is discharged through the gas outlet 5.

Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention shall be included in the protection scope of the present invention.
