Description

Technical Field

[0001] The utility model relates to the technical field of waste treatment, in particular to a material mixing device for waste incineration pretreatment. Background Art

[0002] Hazardous waste refers to solid waste and liquid waste with one of the following characteristics: one or more hazardous characteristics such as corrosiveness, toxicity, flammability, reactivity or infectivity, which may cause harmful effects on the environment or human health and need to be managed in accordance with hazardous waste.

[0003] With the rapid development of the economy and the acceleration of the industrialization process, the output of hazardous waste is increasing. The current methods of hazardous waste disposal include landfill, incineration, solidification, etc. Among them, incineration can effectively reduce the amount of hazardous waste and realize the full utilization of some hazardous waste with calorific value. Therefore, it has become one of the main methods of hazardous waste disposal. The use of pretreatment equipment before incineration of hazardous materials can improve the efficiency of hazardous material treatment.

[0004] The patent with authorization announcement number CN210624530U in the prior art carbonizes hazardous waste by high-temperature flue gas, reduces the working pressure of the crusher, removes moisture and organic matter in the hazardous waste, effectively reduces the amount of hazardous waste incinerated in the furnace, and the flue gas after utilization returns to the incinerator without generating secondary pollution. Among them, viscous hazardous waste materials are one of the wastes. Most companies will choose to treat viscous hazardous waste by mixing, that is, directly mixing viscous hazardous waste with powdered hazardous waste.

The loosened viscous hazardous waste materials will still flow to the bottom along the furnace wall to cause agglomeration, prolonging the ashing time. To this end, we provide a mixing device for waste incineration pretreatment to solve the above problems. Utility Model Content
