I. Project overview
Date of signing: 2020-11-08
Processing materials: comprehensive hazardous waste
Processing capacity: 50t/d
Equipment configuration: φ3.3*15m rotary kiln, φ4*15.5m secondary combustion chamber
In 2020, the 50 tons/day comprehensive hazardous waste incineration disposal project in Liaoning region is designed to achieve harmless disposal of hazardous waste. In view of our company's excellent technical ability and good reputation in the industry, the two sides cooperate again. The design and manufacture of solid (hazardous) waste incineration rotary kiln and secondary combustion chamber equipment used in this project was contracted by our company, and the purchase contract was signed by both parties in November of that year.
The process used for hazardous waste incineration is to complete the process of water evaporation, volatilizing analysis, ignition and combustion of hazardous waste in the rotary kiln. The ash and slag part is discharged from the bottom of the secondary combustion chamber, and the generated flue gas enters the secondary combustion chamber, where it is mixed with the secondary combustion air, and is heated to more than 1100℃ with a residence time of more than 2 seconds to complete the decomposition of dioxins.
II. Solution
The equipment supplied this time is φ3.3*15m rotary kiln and φ4*15.5m secondary combustion chamber. The following solutions are adopted to meet customer needs.
1) To ensure that harmful gases do not leak out: the system has good sealing measures and high furnace negative pressure.
2) Easy operation and maintenance: high equipment operating rate, the annual operating rate can generally reach about 90%.
3) Equipped with a secondary combustion chamber, the flue gas is heated to more than 1100 ° C in the secondary combustion chamber for a residence time of more than 2 seconds, so that the dioxins are decomposed and removed.
4) The incineration technology can not only meet all environmental requirements for the harmless treatment of hazardous waste (medical waste), but also the recommended technology for solving hazardous waste in China.
5) Wide application range, strong material adaptability, large processing capacity, strong moisture resistance fluctuation. The furnace heat load is large, the material incineration is enough to cope with the incineration of a large number of hazardous wastes, even if the calorific value and moisture content of the material have some fluctuations, it can also be incinerated.
