[0015] (III) Beneficial effects

[0016] Compared with the prior art, the utility model provides a hazardous waste incineration treatment device, which has the following beneficial effects:

[0017] 1. The hazardous waste incineration treatment device achieves efficient treatment of hazardous waste by designing a crushing system and an incineration system. The waste first enters the crushing box smoothly through the lower hopper and is effectively crushed by two crushing rods rotating in opposite directions, ensuring that the waste reaches a suitable particle size before entering the incineration area, thereby improving the incineration efficiency and combustion completeness. At the same time, multiple incineration heads in the incineration area provide stable heat through external combustion equipment, ensuring that the waste is completely incinerated at high temperature and reducing the residue of harmful substances. The design of the tapered filter cylinder not only contributes to the uniform incineration of the waste, but also facilitates the collection and treatment of ash. This series of designs together ensure the efficient and safe treatment of hazardous waste and reduce the risk of environmental pollution.

[0018] 2. The device adopts multiple purification measures in flue gas treatment to ensure that the flue gas meets the standards. First, the solid particles in the flue gas are initially filtered out through the through holes on the upper end of the inner wall of the incineration area and the internal filter screen, reducing the impurity content in the flue gas. Secondly, the flue gas is sent into the exhaust pipe through the induced draft fan and extended to the water tank for water quenching cooling, which further reduces the temperature of the flue gas and removes some harmful substances. Finally, before the flue gas is discharged through the chimney, it is double filtered by the filter plate and filter cotton. The activated carbon inside the filter plate effectively absorbs heavy metals and dioxins and other toxic substances in the flue gas, while the filter cotton further filters out tiny particles in the flue gas. This series of purification measures ensures the cleanliness of the flue gas, meets strict environmental protection requirements, and protects the quality of the atmospheric environment.
