Reaction device convenient for total thermal cracking of solid wastes

Abstract

The invention belongs to the technical field of solid waste treatment, in particular to a reaction device convenient for total thermal cracking of solid waste. The device aims to solve the problem that the overall treatment cost is increased due to the fact that an additional device is adopted to dry the solid waste after the solid waste is collected. The reaction device comprises a treatment box, a crushing box is arranged above the treatment box, a damper is fixedly connected between the outer wall of the lower side of the crushing box and the outer wall of the upper side of the treatment box, an exhaust pipe is arranged inside the treatment box, an exhaust assembly is arranged inside the exhaust pipe, a feeding box is arranged on one side of the exhaust pipe, and a drying assembly is arranged inside the feeding box. According to the device, high-temperature gas generated in the solid waste treatment process, the gas is used for drying the to-be-treated solid waste, so that the situation that the thermal cracking and incineration effects are reduced in the treatment process due to the fact that a large amount of liquid is doped in the solid waste is avoided, the overall solid waste treatment time is shortened, and the treatment efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of solid waste treatment, in particular to a reaction device for total thermal cracking of solid waste. Background technique [0002] Solid waste treatment is through physical means (such as crushing, compression, drying, evaporation, incineration, etc.) or biochemical effects (such as oxidation, digestion, decomposition, absorption, etc.) The process of natural purification usually also refers to the solid and muddy substances discarded by human beings in production and living activities, including solid particles separated from waste water and waste gas. [0003] Pyrolysis is the use of thermal energy to cut the chemical bonds of biomass macromolecules under the condition of complete anoxic or limited oxygen supply, and convert them into low molecular liquid bio-oil, combustible gas (hydrogen, methane, carbon monoxide mixed gas) and solid carbon. A three-component process. [0004] The current solid wast...

AI Technical Summary

Problems solved by technology

[0004] The current solid waste treatment process includes thermal cracking and incineration, which is carried out in a reaction device. After the solid waste is collected, because it will be mixed with water, it needs to be dried in advance to improve the overall efficiency of solid waste treatment. Additional The dry treatment of solid waste by the equipment increases the overall cost of treatment
