Hot blade type electronic garbage pyrolysis device

Abstract

The invention relates to the technical field of garbage treatment, in particular to a hot blade type electronic garbage pyrolysis device. The hot blade type electronic garbage pyrolysis device comprises an electronic garbage pyrolysis reactor and an electric heating system, wherein the electronic garbage pyrolysis reactor comprises a material pyrolysis assembly and a reactor shell; the material pyrolysis assembly comprises a spiral casing pipe and a propelling helix; the electric heating system comprises an electric heating wire and a power supply rotating joint; and the two ends of the electric heating wire stretch out along a spiral shaft of the propelling helix to be connected with the power supply rotating joint. The device adopts a spiral blade to heat, the electric heating wire is arranged in the propelling spiral shaft blade, materials perform heat transfer from inside to outside while being propelled by the helix, and the materials are directly heated by the high-temperature blade in the propelling process, so the thickness of a heat-preserving layer is reduced, the utilization rate of heat is increased and the production and manufacturing cost is reduced; meanwhile, the heating spiral blade rotates along with the spiral shaft, so the temperature is more uniform.

Description

technical field [0001] The invention relates to the technical field of waste treatment, in particular to a thermal blade type electronic waste pyrolysis device. Background technique [0002] Due to the continuous change of temperature in the pyrolysis process of electronic waste, the products produced by pyrolysis of materials at different temperatures are different. Through experiments and data collation of related materials, it is found that the temperature is between 300~400℃, and the pyrolysis gas The production speed is accelerated, and at the same time, tar is produced at a temperature between 500 and 550 ° C. Due to the increase in temperature, the tar evaporates rapidly into a gaseous oil-gas mixture after production, and the residual solid is carbonized at a temperature between 650 and 700 ° C to form a solid residue. Because the material is heated by external heating, it is difficult to control the temperature, the temperature measurement is not accurate enough, th...

Problems solved by technology

Due to the use of external heating to heat the material, it is difficult to control the temperature, the temperature measurement is not accurate enough, the heat is concentrated on the tube wall, and the heat is transferred to the material through the tube wall, the heat transfer efficiency is low, and tar is easily bonded, which makes the device efficiency low

For example, the patent literature with the publication number CN101020833A discloses a biomass electromagnetic induction pyrolysis liquefaction reactor, which is characterized in that: it includes a screw feeder set on the support frame, the screw feeder is composed of a shell, An inductance coil is wound on the top; the inductance coil is at least one layer of hollow tubes wound on the shell cylinder, and the hollow core of the hollow tube is the cooling liquid flow channel; the lower port of the slag discharge tube is placed in the water seal tank; The screw shaft is connected to the reducer shaft of the motor; there is an exhaust slot on the axial direction of the screw shaft. The reactor uses electric induction heating as the heat source of the horizontal furnace, but the heating method of the external heat source has not been solved. The problem of heat dissipation loss and fixed position heating, and the use of hollow tube water cooling method for cooling, so that a large amount of heat is absorbed by the cooling water, reducing the efficiency of the equipment
