New hazardous waste incineration rotary kiln

Hazardous waste incineration rotary kiln is mainly used for comprehensive hazardous waste incineration treatment. According to the comprehensive material characteristics and incineration process requirements of hazardous wastes, this type of rotary kiln has the characteristics of complete incineration, strong adaptability, high operation rate, low energy consumption, simple operation and maintenance, etc.

So, what is the working principle of hazardous waste incineration rotary kiln?

Hazardous solid waste (including medical waste) to be treated enters the kiln from the feed end (high-end) of the cylinder for incineration. Due to the tilt and slow rotation of the cylinder, the material from the feeding end (high end) of the cylinder to the discharging end (low end) will produce a comprehensive movement that rolls along the circumferential direction and moves along the axial direction. The solid waste is burned and decomposed in the kiln, and the solid waste after basic treatment is discharged from the discharging end (low end) of the cylinder and enters the secondary combustion chamber for further treatment. The fuel is sprayed into the kiln barrel by the feeding end (high-end) of the barrel, and the heat exchange is completed with the solid waste entering the barrel.

What are the structural characteristics of hazardous waste incineration rotary kiln?

No. 01 Cylinder part

The cylinder adopts two-gear support, the support part is thickened, and the welding adopts automatic submerged arc welding; The kiln tail guard adopts cast heat-resistant steel for easy replacement.

No. 02Supporting device of supporting wheel and supporting device of supporting wheel

The rolling bearing simplifies the supporting wheel structure, improves the reliability of the overall operation, reduces the useless power loss during the operation of the cylinder, and makes the maintenance and overhaul more convenient.

No. 03Transmission part

Using frequency conversion speed regulating motor, the rotating speed can be adjusted at any time according to the specific situation, relying on frequency conversion motor and gear drive system to provide power to rotate and stop rotating. Energy saving and environmental protection, high efficiency, high speed regulation precision and stable operation.

No. 04Auxiliary transmission

The auxiliary transmission motor is adopted to ensure that the rotary kiln can still operate on the plate kiln when the main power supply is interrupted, to prevent the bending deformation of the cylinder and to facilitate maintenance, and it is equipped with electric hydraulic block brake to avoid reverse rotation when the kiln is stopped.

No. 05

Kiln head and tail sealing device

Using three-layer flexible seal (stainless steel seal scale + Carbon silicon aluminum fiber composite plate + stainless steel seal scale) combined with labyrinth structure, the air leakage rate is low, the sealing performance is better, the reliability is higher, and the service life is longer and the replacement is convenient, which can significantly reduce the maintenance cost.
