Multi-stage crushing intelligent treatment device and method for high-water-content slag-state solid waste

Abstract

The invention belongs to the field of solid waste treatment, and particularly discloses a multi-stage crushing intelligent treatment device and method for high-water-content slag-state solid waste. The multi-stage crushing intelligent treatment device comprises a multi-stage crushing and drying module, a thermal cracking reaction module and a negative feedback control module, wherein the multi-stage crushing and drying module comprises multi-stage crushing and drying units connected in sequence. Each crushing and drying unit comprises a crusher and a dryer which are connected, wherein the crusher is used for crushing and granulating the slag-state solid waste, and the dryer is used for drying and dehydrating the slag-state solid waste. The thermal cracking reaction module comprises a thermal cracking reactor, wherein the thermal cracking reactor is connected with the last-stage dryer and is used for carrying out thermal cracking reaction on the crushed and dried slag-state solid waste.The negative feedback control module is used for monitoring the quality of cracking oil and cracking slag, controlling the working frequency and power of the crushers and further controlling the thermal cracking reaction degree. According to the multi-stage crushing intelligent treatment device, the intelligent treatment of the slag-state solid waste is realized, the treatment efficiency and thequality of cracking oil and cracking gas are improved, and meanwhile, the energy consumption is reduced.

Description

technical field [0001] The invention belongs to the field of solid waste treatment, and more specifically relates to a multi-stage crushing intelligent treatment device and method for slag-state solid waste with high water content. Background technique [0002] With the continuous improvement of enterprise production capacity and people's living standards, in recent years, the total amount of solid waste has increased year by year, including meal waste, kitchen waste, medical waste, organic sludge, waste electronic components, waste tires, etc. . Among them, organic solid waste with high moisture content (>50%) is more difficult to handle than ordinary dry solid waste due to its higher moisture content and higher viscosity. [0003] At present, the main organic solid waste treatment methods include landfill treatment, incineration treatment, pyrolysis treatment, biocomposting and so on. At present, the most widely used method of organic waste treatment is incineration, ...
