Embodiment 1
[0051] The electric heating system is heated by electric heating wire. The diameter of the electric heating wire is 1.4mm and the total length is 15m. It is wound on the blade. Electronic waste materials (circuit boards, wires, keyboards, etc.) 1kg / h, the final pyrolysis slag is 0.8kg / h, and the pyrolysis oil gas is 0.286 Nm3 / h, which realizes continuous material in and out. During the pyrolysis process, the temperature is kept at 650°C, and the heat source is very stable, thereby eliminating tar clogging. The temperature of the hot nitrogen is 550°C, and the material is preheated, so that the material is heated to about 500°C before entering the screw propeller, and then Enter the heating spiral. The amount of nitrogen gas is 10L / min.

Abstract
The invention relates to the technical field of waste pyrogenic decomposition, in particular to a hot nitrogen preheated electronic waste pyrogenic decomposition handling equipment. The equipment includes an electronic waste pyrogenic decomposition reactor and an electronic heating system, wherein, the electronic waste pyrogenic decomposition reactor includes a material pyrogenic decomposition component and a reactor shell, the electronic heating system includes a hot nitrogen preheating system, a heating module for providing heat supply and an insulation layer for ensuring the insulation of electronic heating wire in the heating module and the screw shell body in the material pyrogenic decomposition component. The equipment satisfies the temperature requirements of electronic waste pyrogenic decomposition, while preheats material, settles the issues of uneven temperature, slow heating, sticky coal tar, strong heat radiation and the like in the reactor, achieves the purpose of continual gas production; when adopting hot nitrogen to preheat the material, the hot nitrogen insults air and at the same while preheats and removes the coal tar of material, bringing huge improvement for inner screw coal tar stickiness imagination.
Description
technical field [0001] The invention relates to the technical field of garbage pyrolysis, in particular to a thermal nitrogen gas preheating electronic garbage pyrolysis 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 board...
