Medical Waste Incineration kiln & Secondary Combustion Chamber Project in Guiyang, Guizhou
50 t/d
Guiyang, Guizhou
Project Location: Guiyang, Guizhou
Main Equipment: ø3.6x13m rotary kiln & second combustion chamber
Capacity: 50 t/d
Working conditions:
50t/d of solid waste is often incinerated under the rotary kiln. Low calorific value of material: 4000kcal/kg. In addition to solid materials, low calorific value liquid materials need to be fed into the rotary kiln, and high calorific value waste liquid is injected into the secondary combustion chamber.
The working temperature in the rotary kiln is 850-1000°C. The ash generated after incineration falls directly into the water-sealed slag discharging device at the bottom of the rotary kiln. The rotary kiln is lined with 230mm heavy bricks.
The working temperature in the secondary combustion chamber is 1100-1200℃. The secondary combustion chamber is lined with 200mm heavy bricks + 100mm aluminum silicate fiber board.
The flue gas delay device is set at the outlet of the secondary combustion chamber. The flue gas goes in and out at the top and the working temperature is 1100-1200°C. The secondary combustion chamber is lined with 200mm heavy bricks + 100mm aluminum silicate plates.
Major equipment:
The inner diameter of the rotary kiln barrel is φ3600mm and the length is 13000mm. Tilt angle 2 degrees. Driven by the transmission device: main motor (frequency conversion), main reducer, and gear ring gear. The rotary kiln is equipped with an auxiliary motor and an auxiliary reducer for maintenance. The kiln head cover, the sealing device between the kiln head and the cylinder body, the sealing device between the kiln tail and the inlet of the cyclone dust collector, and the supporting wheel device, etc., are sealed with fish scales and labyrinth seals.
System Features:
The hazardous waste incineration system is mainly based on the 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, and provides customized whole-process services for the owner to ensure that pollutants emissions meet current standards.
Outstanding advantages:
1. Provide a complete whole industry chain service, with a complete solid waste treatment system solution;
2. Advantages of hazardous waste products: high-temperature incineration to achieve harmlessness, reduction, stabilization, and recycling;
3. Advantages of solid waste products: resource disposal, waste utilization, production of building ceramsite;
4. The heat load of the furnace is large, and the materials are fully incinerated, which is enough to deal with the full incineration of a large amount of hazardous waste.
Application scope:
It is suitable for various tailings, tailings slag, papermaking white mud, carbide slag, aluminum ash, polluted soil, urban medical waste, domestic sludge, municipal sludge, acid sludge, etc.
