[0028] In this invention, firstly, the staff introduces the flue gas generated from the incineration of hazardous waste into the filter box 1 through the inlet pipe 4. Large dust particles in the flue gas are filtered out through the filter screen 5 in the filter box 1. Then, the drive motor 7 is turned on, causing the drive shaft 8 to rotate. The drive shaft 8 drives the cleaning plate 9 to clean the surface of the filter screen 5, scraping off the dust and extending the service life of the filter screen 5. This prevents the filter screen 5 from becoming clogged due to dust accumulation. While the dust is being cleaned, the drive shaft 8 also... Two pulley assemblies 11 drive two rotating shafts 10 to rotate. The rotating shafts 10, through two bevel gears 13, drive the reciprocating screw 12 to rotate, causing the reciprocating block 16 to reciprocate along the outer groove of the reciprocating screw 12. This, in turn, causes the pushing block 15 to reciprocate. The pushing block 15 pushes the dust from both sides towards the center, allowing the dust to be directly collected by the waste bin 26, eliminating the need for manual collection. After filtration, the flue gas continues to be transported backward by the suction of the induced draft fan 6. In the quench tower 2, the flue gas is further cooled and discharged. The water mist sprayed by the spray plate cools the flue gas and converts water-soluble harmful gases into wastewater for treatment. Workers pour the prepared chemical reagents into the feed inlet 17 and rotate one of the shafts 18 by turning the handle. This shaft 18, via two spur gears 20, drives another shaft 18, causing the crushing roller 19 to crush the lumpy chemical reagents, eliminating the need for manual crushing. The crushed chemical reagents react more effectively, accelerating the reaction rate. During crushing, one of the shafts 18 also drives a rotating rod 21 via a bevel gear 22. The rotating rod 21, via a pulley assembly 24, drives a central shaft 23, which in turn stirs the wastewater containing the chemical reagents on the mixing plate 25. This ensures the wastewater reacts faster and more completely, preventing unreacted wastewater. Wastewater is discharged only after the reaction is complete and meets emission standards. The flue gas, drawn by the induced draft fan 6, is adsorbed by the activated carbon in the purification box 3, thus meeting emission standards before being discharged.
