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

Abstract

The invention belongs to the field of solid waste treatment, and specifically discloses a multi-stage crushing intelligent treatment device and method for high moisture content slag state solid waste, which includes a multi-stage crushing and drying module, a thermal cracking reaction module and negative feedback control module, wherein: the multi-stage crushing and drying module includes successively connected multi-stage crushing and drying units, and the crushing and drying unit includes a connected crusher and a dryer. Carry out drying and dehydration; the thermal cracking reaction module includes a thermal cracking reactor, which is connected to the last stage dryer, and is used to perform thermal cracking reaction on the crushed and dried slag solid waste; the negative feedback control module controls the pyrolysis oil Monitor the quality of pyrolysis slag, control the working frequency and power of the crusher, and then control the degree of pyrolysis reaction. The invention realizes the intelligent treatment of slag-state solid waste, improves the treatment efficiency and the quality of pyrolysis oil and pyrolysis gas, and saves energy consumption at the same time.

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, ...

AI Technical Summary

Problems solved by technology

[0007] In view of the above defects or improvement needs of the prior art, the present invention provides a multi-stage crushing intelligent treatment device and method for high moisture content slag solid waste, the purpose of which is to The quality change is monitored, and the pretreatment crushing and granulation process before pyrolysis is directional controlled, thereby changing the heat transfer process of pyrolysis, avoiding the material thermal stress fatigue problem caused by the existing device regulating the heating temperature in the pyrolysis process and adopting The spiral pyrolysis reactor adjusts the sticking and clogging problems caused by the pyrolysis residence time of slag-state solid waste, breaking through the current situation of traditional slag-state solid waste treatment "one solid waste, one device" and the low intelligence of solid waste pyrolysis treatment
