The hazardous waste rotary kiln incinerator is rotary kiln equipment widely used in the field of international industrial waste treatment, and its market share in the field of hazardous waste incineration is as high as 85%. Hazardous waste rotary kiln incinerator is designed to deal with a variety of refractory substances or large changes in moisture waste incineration. Because the combustion furnace of the rotary kiln incinerator operates at a certain speed, the residence time of solid waste on the surface of the rotary kiln will change with different speeds.
During the combustion process of the solid waste rotary kiln combustion furnace, the solid waste is subjected to strong mechanical collision in the high-temperature air and excessive oxygen. After the solid waste is completely incinerated in the rotary kiln, slag with a very low content of flammable matter and putrefied matter can be obtained. Therefore, the solid waste rotary kiln can handle a wide range of waste, especially in the field of hazardous waste incineration.
The solid waste rotary kiln incinerator provided by AGICO can process various materials in the form of solid, liquid, gas, or sludge. Enterprises with the following material treatment needs are recommended to purchase rotary kiln incinerator for solid waste treatment. These materials usually include:
- Industrial waste
- Chemical material
- Medical waste (Medical Waste Rotary Kiln Incinerator)
- Petrochemical products
- Domestic garbage
- Contaminated organic waste
- Sludge (Sludge Waste Rotary Kiln Incinerator)
- Waste batteries
Hazardous Waste Rotary Kiln Incinerator Working Process
The working process of rotary kiln incinerator mainly includes water evaporation, volatile de-volatilization, and ignition combustion of solid waste.
When the rotary kiln incinerator is working, the furnace body drum is rotated, and the material is brought to the upper part of the cylinder by the high-temperature resistant lining plate on the inner wall, and the solid waste falls due to its own gravity. The solid waste rolls up and down in the cylinder and is in full contact with the air. Complete combustion is carried out through three stages of ignition, combustion, and burnout.
When the rotary incinerator starts to work, the solid waste is sent into the kiln from one end of the drum, and the hot flue gas is used to dry it first. During this period, the temperature in the furnace continues to rise. When the ignition temperature is reached, the solid waste starts to burn. With the rotation of the cylinder, the solid waste is burned out in the rotary kiln, and finally, the ash is discharged at the outlet of the cylinder.
When the water content of the solid waste is too large, a grate can be added to the rotary kiln incinerator process, that is, the second combustion chamber link. The flue gas discharged from the drum of the rotary kiln enters the second combustion chamber, where it is mixed with the air of the second combustion in the second combustion chamber for full combustion. After the secondary combustion process, all the flue gas can be burned, so as to achieve the goal of safe exhaust gas emission.
