Solid waste recycling treatment technology

Abstract

The invention discloses a solid waste recycling treatment technology. The technology comprises a solid waste pretreatment stage, a pyrolysis stage, a condensation stage and a classified collection stage. The technology specifically comprises the steps that solid wastes are loaded into a collection hopper to be subject to preliminary screening, magnetic metal is sorted out, smashed and fed into a pyrolysis reactor to be subject to pyrolysis, steam, liquid fractions and gas generated after pyrolysis are cooled through a water cooling tank, components condensed into liquid in the water cooling tank are collected, the condensed gas is subject to low-temperature liquefying through a liquefying device and is collected, and solid residue obtained after pyrolysis is conveyed to an ash dividing hopper; the solid waste treatment technology is simplified, anaerobic heating is carried out through a spiral stirring heating pipe, the pyrolysis steps are simplified, the solid phase, the liquid phase and the gas phase generated after pyrolysis are collected in a classified manner, gas fuel, liquid fuel and solids used for building materials can be obtained, waste disposal is reduced, natural resources are sufficiently utilized, and emissions of harmful substances are reduced.

Description

technical field [0001] The invention relates to the technical field of environmental protection, in particular to a solid waste recycling process. Background technique [0002] With the continuous development of the industrial economy, a large amount of industrial waste cannot be disposed of in time. Most of the industrial waste is in the form of solid waste and liquid waste, which contain a large amount of toxic and harmful substances, heavy metals such as arsenic, copper, chromium, and mercury. , Improper handling will cause irreversible damage to the surrounding soil environment and atmospheric environment. Biomass pyrolysis gasification technology is a process of converting solid biomass into gaseous fuels through thermochemical reactions. The gaseous products can be used for power generation, gas supply, and central heating. However, the traditional gasification technology has problems such as low calorific value of gas, high tar content, and difficult treatment of was...
