Description

Waste treatment incinerator Technical Field The utility model relates to the technical field of incineration, in particular to a waste treatment incinerator. Background Hazardous waste incineration is a key measure for guarding ecological safety and realizing resource circulation. In the treatment process, the pyrolysis can reduce the volume of the solid dangerous waste, effectively lighten the load of a landfill site and release precious land resources. Meanwhile, the ultra-high temperature generated by incineration can collapse the molecular structure of heavy metals and organic pollutants, kill pathogens and radically eliminate the threat to the environment and human health. In addition, the incinerated ash slag also contains valuable metals such as iron, copper and the like, and can be put into production again through extraction. According to the hazardous waste safety incineration device disclosed by the authority bulletin number (CN 222578238U), the hazardous waste safety incineration device comprises an incinerator and a conveying pipe obliquely fixed at the upper part of one side of the incinerator, wherein an inner cylinder is fixedly arranged in the conveying pipe. When the incinerator is used for incinerating, the extruded and compacted hazardous waste is conveyed into the incinerator for incineration, and the stirring rod can effectively stir the burnt hazardous waste to avoid the accumulation of the hazardous waste when rotating. The structure disclosed in the patent has defects in practical application, and particularly, in the process of burning dangerous waste at high temperature, the temperature in the incinerator can reach hundreds or even thousands of degrees centigrade, and the continuous high-temperature environment leads the inner wall material of the incinerator to generate obvious thermal expansion. Due to the lack of effective thermal stress release and buffer design, repeated thermal expansion and contraction cause fatigue damage in the material, and as time goes on, the inner wall is easy to crack, peel off and other problems, so that the structural integrity and the service life of the incinerator are seriously affected, the equipment maintenance cost is increased, potential safety hazards are possibly caused, and the incineration treatment efficiency and stability are reduced.
