The rotary kiln and secondary combustion chamber supporting equipment used in this project are used for comprehensive chemical hazardous waste treatment. The plan is unique and the effect is good. It has the following characteristics:

1) This incineration technology not only meets all environmental requirements for the harmless treatment of hazardous waste (medical waste), but is also the recommended technology for solving hazardous waste in my country.

2) Wide application range, strong material adaptability, large processing capacity, and strong resistance to fluctuations in moisture content. The furnace has a large heat load and complete incineration of materials, which is sufficient for complete incineration of a large amount of hazardous waste. Even if the heating value and moisture content of the materials fluctuate, they can be completely incinerated.

3) The temperature of the flue gas at the outlet of the rotary kiln is 800～850℃, which can decompose the harmful components in the comprehensive hazardous waste. After the flue gas enters the second combustion chamber, it is heated and burned again. It stays in the high temperature zone greater than 1100℃ for more than 2 seconds, completely Removal of dioxins in the flue gas.
