Description

Technical Field

[0001] The utility model belongs to the technical field of incineration devices, in particular to a hazardous waste safety incineration device. Background Art

[0002] Waste becomes hazardous waste because it contains toxic and harmful chemical components. The chemical components contained in it will pollute the environment and cause great harm to human health. Burning organic waste at high temperature is a method of eliminating hazardous waste. During the chemical transformation and disposal of hazardous waste, secondary pollution should be reduced as much as possible to reduce or eliminate the harm of waste to the environment or health. Therefore, it is necessary to use hazardous waste incineration equipment for incineration treatment.

[0003] When incinerating hazardous waste, it is usually dumped directly into the interior of the incinerator. However, many hazardous wastes contain a large amount of water. Direct incineration will result in a long incineration time and high energy consumption. At the same time, the hazardous waste accumulated inside the incinerator is in a static state, which will result in the hazardous waste at the bottom not being fully and effectively burned and affecting the combustion efficiency. Therefore, improvements are needed to address the above problems. Utility Model Content
