Solid waste rotary kiln

Solid waste and hazardous waste rotary kilns offer a wide range of advantages for handling complex industrial and medical waste, including stable and reliable operation, easy management and operation, and simplified equipment maintenance. Therefore, they are widely used in international hazardous waste incineration. Incineration is a relatively reliable and effective means of harmlessly disposing, reducing, and recycling solid and hazardous waste.

Capacity: 10-120 tons/day (depending on the moisture content of the material).

Specifications: Ø2.2×9m-Ø4.5×16m

Calcination Temperature: 850-1200°C

Applications: Suitable for the disposal of various solid and hazardous wastes in the medical, industrial, petroleum, and chemical industries.

Operating Principle

The rotary kiln features a pusher at the feed inlet to ensure continuous material feeding. The rotary kiln outlet temperature is 800-850°C. After the flue gas enters the secondary combustion chamber, secondary air is injected tangentially around the chamber, creating a strong vortex field within the chamber, ensuring the complete combustion of the combustible components in the flue gas. The unique structural design of the secondary combustion chamber also enables it to function as a cyclonic dust removal system. The flue gas outlet temperature exceeds 1100°C, and the flue gas resides in the high-temperature zone for more than two seconds, ensuring the complete decomposition of harmful components in the flue gas, including dioxins, and meeting the requirements for hazardous waste incineration. Solid (hazardous) waste is fed into the rotary kiln through the feeding mechanism for high-temperature incineration. After high-temperature incineration, the material is burned into high-temperature flue gas and ash. The rotation speed of the rotary kiln can be adjusted. Maintaining a stable slag layer of about 50mm thick can protect the refractory layer. Its operating temperature should be controlled at around 850℃. The high-temperature flue gas and ash enter the secondary combustion chamber from the kiln tail, and the incineration ash enters the slag discharger from the kiln tail and is regularly sent to the stabilization/solidification workshop for treatment.
