A pyrolysis furnace for electronic waste

Abstract

The invention discloses an electronic waste pyrolyzing furnace which comprises a pyrolyzing furnace body, a combustion system, a conveyer system and an electrical control system, wherein the pyrolyzing furnace body is horizontal; a feeding hole is formed in the furnace end of the pyrolyzing furnace body; a discharging hole is formed in the furnace tail of the pyrolyzing furnace body; an area between the furnace end and the furnace tail is sequentially divided into a preheating section, a pyrolyzing section, a thermal insulating section and a cooling section; a heating support plate for sealing the pyrolyzing furnace body is arranged at the bottom of the pyrolyzing furnace body; the conveyer system comprises an annular belt and a dragging wheel group; two ends of the annular belt are erected on the dragging wheel group; an upper moving part is erected on the heating support plate; and the combustion system is arranged below the pyrolyzing section and the thermal insulating section of the pyrolyzing furnace body. The electronic waste pyrolyzing furnace is low-carbon, efficient and high in sealing property, can carry out automatic continuous treatment and is particularly suitable for electronic waste treatment.

Description

technical field [0001] The invention relates to a pyrolysis furnace, in particular to an electronic waste pyrolysis furnace, which belongs to the field of electronic waste resource recovery and reuse. Background technique [0002] At present, in the era of rapid development of the electronic information industry, more and more electronic waste to be processed is an urgent problem that the industry needs to solve. Different from ordinary hazardous waste, e-waste has dual characteristics of resource and danger. Therefore, the safe disposal of e-waste as a resource is a hot spot in the industry. At present, the current status of e-waste treatment in my country can be summarized as "huge quantity, high value, backward technology, and serious pollution". The level of various treatment technologies varies, among which pyrolysis technology has received widespread attention and praise from the industry. [0003] The key equipment for the pyrolysis treatment of electronic waste is t...

Problems solved by technology

In this plan, the pyrolysis furnace is not sealed, and the organic components in electronic waste will generate dioxin-like pollutants in an aerobic environment. The rapid cooling dioxin decomposition plan in the plan is difficult to operate and has low precision; In addition, the pyrolysis furnace in this scheme has no material conveying device, the continuity is poor, the pyrolysis cycle is long, and the working efficiency of the kiln is low
