Embodiment Construction

[0016] The present invention is described in further detail below in conjunction with specific embodiments:

[0017] like figure 1 A solid waste recycling process shown includes a solid waste pretreatment stage, a pyrolysis stage, a condensation stage, and a classified collection stage; the solid waste pretreatment stage is to put solid waste into a collecting hopper, and The screening device conducts preliminary screening of solid waste. The screening device mainly uses manual methods to screen out non-magnetic non-ferrous metals, broken glass, and concrete. The screening device includes an angle of 30° with the horizontal plane. The conveyor belt, the upper end of the conveyor belt is connected with the collecting hopper; then the magnetic metal in the solid waste is sorted out by a magnetic separator, and the magnetic separator is arranged on the top of the screening device. When the solid waste passes through the conveyor belt The magnetic metal can be sucked away, and th...

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...
