Deodorization device based on pyrolysis solid waste treatment

Abstract

The invention relates to the technical field of solid waste treatment, and discloses a deodorization device based on pyrolysis solid waste treatment, the deodorization device comprises a tooth roller type crusher and a washing tower, and the top of the tooth roller type crusher is respectively provided with a transition box body part and a crushing feed port. After the transition box body part, the composite solid-gas filtering part, the first composite pipe fitting, the air blower, the pre-purification adsorption part, the second composite pipe fitting and the two anti-interference pipe fittings which are arranged are assembled in a matched mode, a pre-purification treatment mechanism can be formed; the malodorous gas generated after solid waste is crushed is conveyed and subjected to purification pretreatment in a constant phase change negative pressure adsorption mode, the operation load of the washing tower is reduced, the filtering adsorption medium placed in the pre-purification adsorption part makes contact with the malodorous gas in a circulating activity mode and purifies the malodorous gas, the filtering adsorption medium is fully utilized, and the use cost is reduced.

Description

technical field [0001] The invention relates to the technical field of solid waste treatment, in particular to a deodorization device based on pyrolysis method for solid waste treatment. Background technique [0002] Pyrolysis treatment of solid waste refers to heating solid waste under anaerobic or anoxic conditions to decompose it, converting it into storable and easily transportable energy such as gas fuel and fuel oil, or recycling resource products (such as pyrolysis liquid products). As a technical measure for chemical raw materials), since pyrolysis is carried out under anaerobic or anoxic conditions, its exhaust gas volume is smaller than that of incineration. It is mainly used in the treatment and utilization of municipal solid waste, sludge, waste plastic, waste rubber and other wastes. [0003] At present, in the process of pyrolysis treatment of solid waste, if the solid waste particles are large, the heat transfer rate and mass transfer rate will be slow, and t...

AI Technical Summary

Problems solved by technology

[0003] At present, in the process of pyrolysis treatment of solid waste, if the solid waste particles are large, the heat transfer rate and mass transfer rate will be slow, and the secondary reaction of pyrolysis will increase, which will have an adverse effect on the product composition, while smaller particles will promote heat transfer. Therefore, it is necessary to properly crush and pretreat the pyrolysis raw materials so that the particle size is both fine and uniform. There are still some problems. Although the conventional filter structure adopted can filter malodorous gas and solid particles in the early stage, it is prone to clogging in the subsequent use process, delaying the treatment efficiency and reducing the treatment effect. Therefore, in view of the above problems, this application will Provide a deodorization device based on pyrolysis solid waste treatment to solve the problem
