Problems solved by technology

[0019] These factors lead to the incineration residue of hazardous waste from social sources cannot be directly processed by high-temperature melting in the form of continuous feeding
[0020] However, the above-mentioned prior art for high-temperature melting treatment of hazardous waste incineration residues lacks a systematic pretreatment process for hazardous waste incineration residues, only simple crushing pretreatment, which severely restricts the application of high-temperature melting treatment of hazardous waste incineration residues from social sources.

Abstract

The invention discloses a pretreatment method and device for social source hazardous waste incineration residues. The pretreatment method comprises the steps of dry-wet separation, sorting, crushing, drying, compatibility, homogenizing and the like. The pretreatment device comprises a dry material treatment system, a wet material treatment system, a fine crushing buffer bin, a fine crusher, an eddy current sorting system, a storage bin, a metering device, a compatibility and homogenizing device and a charging bin. According to the pretreatment method and device for the social source hazardous waste incineration residues, a to-be-melted material with stable components and uniform particle size distribution is obtained, and rapid and uniform mass and heat transfer of the material in a melting process is facilitated so that the melting efficiency can be improved, many problems of the social source hazardous waste incineration residues are solved, and the requirements of high-temperature melting on the material charged into a furnace are met.

Description

technical field [0001] The invention belongs to the technical field of hazardous waste treatment, and in particular relates to a method and a device for pretreatment of social source hazardous waste incineration residues. Background technique [0002] The centralized treatment of hazardous waste, mainly industrial waste, started relatively late in China, but has developed rapidly. At present, incineration technology is used to treat hazardous waste in many places. According to my country's "National Hazardous Waste List (2021 Edition)" and other regulations, hazardous waste incineration residues are still hazardous waste. [0003] At present, the disposal methods for hazardous waste incineration residues are mainly landfill and cement kiln coordination. The disadvantages of these two methods are: landfill cannot completely solve the hazardous characteristics of hazardous waste incineration residues, and at the same time occupy a large amount of land resources, which is not ...
