Spiral heat accumulating type gas electronic trash pyrolysis device and method

Abstract

The invention discloses a spiral heat accumulating type gas electronic trash pyrolysis device. The spiral heat accumulating type gas electronic trash pyrolysis device comprises an electronic trash pyrolysis reactor and a heat accumulating type gas heating system. The electronic trash pyrolysis reactor comprises a reactor shell and a material pyrolysis assembly. The material pyrolysis assembly transversely penetrates through the reactor shell. The heat accumulating type gas heating system comprises a heat accumulating type combustion device, a smoke channel and a flue screw. The smoke channel is a closed spaced formed between the reactor shell and the material pyrolysis assembly in a matched mode. The smoke channel communicates with the heat accumulating type combustion device. The flue screw is arranged in the smoke channel. The invention further discloses a method for conducting pyrolysis on electronic trash using the pyrolysis device. The method comprises the two steps of heating of a spiral shell through the heat accumulating type gas heating system and material pyrolysis. By means of the pyrolysis device and the method, continuous material feeding and discharging can be achieved, the heat source stability is good, the pyrolysis process is simple, and the pyrolysis efficiency is high.

Description

technical field [0001] The invention belongs to the technical field of garbage pyrolysis, and in particular relates to a spiral regenerative gas-fired electronic waste pyrolysis device and a pyrolysis method. Background technique [0002] In recent years, all kinds of electronic products are changing with each passing day, and the new and old replacements are getting faster and faster, and the resulting electronic waste is increasing exponentially. The heavy metal elements contained in it will seriously pollute the environment. If electronic waste is not handled properly, it will produce toxic and harmful gases such as dioxin, causing secondary pollution. At present, the processing methods for electronic circuit boards mainly include mechanical physical methods, metallurgical extraction methods, biological treatment methods, and pyrolysis methods, among which mechanical physical methods, metallurgical extraction methods, and biological treatment methods mainly focus on the m...
