Single-heat storage pulse type electronic waste heat treatment device

Abstract

The invention relates to the technical field of waste pyrolysis, and particularly relates to a single-heat storage pulse type electronic waste heat treatment device. The single-heat storage pulse type electronic waste heat treatment device comprises an electronic waste pyrolysis reactor and a single-heat storage type gas heating system, wherein the electronic waste pyrolysis reactor comprises a material pyrolysis assembly, and the material pyrolysis assembly comprises a spiral shell and a material auger; the single-heat storage type gas heating system comprises a heater shell, a single-heat storage type burning device and a fume channel of the heater shell, and the single-heat storage type burning device communicates with the heater shell and extends to the fume channel of the heater shell; and the single-heat storage type burning device comprises a plurality of groups of single-heat storage type burners, each group is composed of two single-heat storage type burners, and each single-heat storage type burner comprises a combustion chamber and a heat storage chamber. According to the device, a pulse type burning mode in pairs is adopted, so that a material accumulation section can be heated in real time, the heat utilization rate is high, and additionally, the load for the whole heating of equipment is reduced.

Description

technical field [0001] The invention relates to the technical field of waste pyrolysis, in particular to a single heat storage pulse type electronic waste heat treatment device. 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 metal in circuit boards. Recycl...
