Abstract
Description
Technical Field

[0002] The rotary kiln is a slightly inclined steel hollow cylinder with refractory material inside. It was first used to burn cement, lime and other materials, and later gradually used for the disposal of hazardous waste. After the hazardous waste enters the rotary kiln, it moves from one end to the other as the rotary kiln rotates. During the movement, the waste is gradually burned, the residue is discharged from the bottom, and the flue gas enters the secondary combustion chamber. The rotary kiln can effectively treat hazardous waste in various forms (solid, liquid, etc.), has strong adaptability to hazardous waste, mature technology, reliable operation, and relatively simple operation. It can well meet the requirements of various hazardous incineration in terms of feeding and slag discharge, and has been widely adopted by the industry.
