Medical Waste Incineration Kiln + Secondary Chamber Project (Guiyang, Guizhou, CHINA)

I. Project overview

1. Working conditions

Under the rotary kiln, solid waste is usually incinerated at 50t/d. Low calorific value of the material: 4000kcal/kg, in addition to solid materials in the rotary kiln, low calorific value liquid materials need to be injected, and high calorific value waste liquid is sprayed in the secondary combustion chamber.

The operating temperature in the rotary kiln is 850-1000℃, and the ash and slag generated after incineration fall directly into the water sealed slag discharge device at the bottom of the rotary kiln. The rotary kiln is lined with 230mm heavy brick.

The working temperature of the secondary combustion chamber is 1100-1200℃. The secondary combustion chamber is lined with 200mm heavy brick +100mm aluminum silicate fiberboard.

The flue gas delay device is arranged at the exit of the secondary combustion chamber, and the flue gas goes up and down, and the working temperature is 1100-1200℃. The secondary combustion chamber is lined with 200mm heavy brick +100mm aluminum silicate plate.

2. Main equipment

The inner diameter of rotary kiln barrel is φ 3600mm, the length is 13000mm. Tilt Angle 2 degrees. By the transmission device: main motor (frequency conversion), main reducer, gear ring drive. Rotary kiln is equipped with auxiliary motor and auxiliary reducer for maintenance. Kiln head cover, kiln head and cylinder seal device, kiln tail and cyclone inlet seal device and wheel support device, etc., the seal adopts fish scale and labyrinth seal.

3. System characteristics

The hazardous waste incineration system is based on rotary kiln + secondary combustion chamber incineration technology, adopts advanced and mature technology at home and abroad, determines the process route and equipment configuration according to the characteristics of the treated materials provided by the owner, provides the owner with customized whole process services, and ensures that the pollutant discharge meets the current standard.

II. Solution

Outstanding advantage

1, to provide a complete whole industry chain services, with a complete solid waste treatment system solutions;

2, the advantages of hazardous waste products: high temperature incineration, to achieve harmless, reduction, stability, resources;

3. Advantages of solid waste products: primitive disposal, waste utilization, production of building ceramics;

4, the furnace heat load is large, the material incineration is sufficient, enough to cope with a large number of hazardous waste incineration.

Scope of application

Suitable for industrial comprehensive solid waste, hazardous waste, chemical, pesticide and other industries of all kinds of tailings, tailings, slag, paper white mud, calcium carbide slag, aluminum ash, contaminated soil, urban medical waste, domestic sludge, municipal sludge, acid sludge, etc.
