Product Description

Solid (dangerous) waste rotary kiln

Solid waste and hazardous waste rotary kiln has many advantages such as wide adaptability, stable and reliable operation, convenient management and operation, and simple equipment maintenance to deal with complex industrial waste and medical waste, so it is widely used in the incineration and disposal of hazardous waste in the world. Incineration is a reliable and effective means to realize harmless, reductive and resource utilization of solid and hazardous waste.

Capacity: 10-120t/d (depending on the water content of the material)
Specification Model: Ø2.2×9m-Ø4.5×16m
Calcination temperature: 850-1200℃
Application: It is used for the disposal of all kinds of solid hazardous waste in medical, industrial, petroleum, chemical and other industries.

Solid (dangerous) waste rotary kiln product introduction
At present, the comprehensive solid (hazardous) waste incineration system is based on rotary kiln + secondary combustion chamber incineration technology, using advanced and mature technology at home and abroad, according to the characteristics of the materials provided by the owner to determine the process route and equipment configuration, to provide the owner with customized whole process services, to ensure that the emission of pollutants meet the current standards.

From the overall project planning to the detailed process formula, process design, equipment design and manufacturing, engineering installation, commissioning and so on to provide a complete whole industry chain services, with a complete solid (hazardous) waste treatment system solutions.

Outstanding advantage
1, to provide a complete whole industry chain services, with a complete solid (dangerous) waste treatment system solutions;
2, the advantages of hazardous waste products: high temperature incineration, to achieve harmless, reduction, stability, resources;
3, all kinds of sludge and other solid waste products advantages: resource disposal, waste utilization, production of building ceramics;
4, the furnace heat load is large, the material incineration is thorough, enough to cope with the complete incineration of a large number of hazardous waste.

Working principle

The rotary kiln is equipped with a push device at the feed port to ensure continuous feed. The outlet temperature of the rotary kiln is 800 ~ 850℃, and after the flue gas enters the secondary combustion chamber, secondary air is tangentially injected around the secondary combustion chamber, so that a strong vortex field is formed in the secondary combustion chamber, and the combustible components in the flue gas can be fully burned. At the same time, the secondary combustion chamber adopts the unique structural design to make the secondary combustion chamber have the function of swirling wind dust removal. The outlet smoke temperature of the secondary combustion chamber is greater than 1100 ° C, and the residence time of the smoke in the high temperature zone is more than 2 seconds, which ensures the thorough decomposition of the harmful components including dioxins in the smoke, and meets the requirements for the incineration of hazardous waste. Solid (dangerous) waste is sent into the rotary kiln through the feeding mechanism for high temperature incineration. After high temperature incineration, the material is incinerated into high temperature flue gas and ash slag. The rotating speed of the rotary kiln can be adjusted, and the stable slag layer of about 50mm thick can play the role of protecting the refractory layer. The high-temperature flue gas and ash enter the secondary combustion chamber from the kiln tail, and the incineration ash enters the slag extraction machine from the kiln tail and is regularly sent to the stabilization/solidification workshop for treatment.
