Problems solved by technology

And because the whole process of plasma arc pyrolysis is carried out in an oxygen-deficient reducing hydrogen environment, Cu, Ni and other metal oxides do not exist, so there is no opportunity for catalytic synthesis of dioxins.

Embodiment Construction

[0022] The invention includes the structure of the sealing system of the plasma pyrolysis reaction kettle, the selection of the furnace body, the ultra-high temperature refractory material, the feeding material and the electrode lifting structure, so as to ensure the safety of the reactor in the ultra-high temperature environment and thoroughly process the dangerous waste .

[0023] The invention can be used for high-temperature discharge of plasma arc, and provides high-temperature cracking energy for waste in a closed reaction kettle. The ultra-high heat generated in the plasma reactor will tear the organic molecular structure of the material to produce simpler gas molecules, and the inorganic part will be melted to form a glass-like substance.

[0024] Due to the different forms and physical properties of hazardous waste materials, different feeding systems, high-temperature cracking furnaces, glass bodies, metal melt discharge heat valves, and the processing capacity of ta...

Abstract

The invention discloses a high-temperature plasma cracking reaction kettle. The high-temperature plasma cracking reaction kettle mainly comprises a reaction kettle body (1), an electrode lifting structure (2), a feeding structure (3) and a metal melt discharging valve (4), wherein the reaction kettle body is of a graphite crucible type; lining structures made from various materials are arranged from outside to inside of the reaction kettle body; the electrode lifting structure (2) adopts an internal bracket lifting lead screw transmission form; and the feeding structure adopts a structural form with a channel (33) of a hopper (31) and a spiral body (32). The high-temperature plasma cracking reaction kettle has a compact structure, and is low in cost and easy to popularize, use, maintain and repair.

Description

technical field [0001] The invention relates to a reaction kettle, especially the reaction kettle uses the high temperature of plasma pyrolysis to decompose the organic matter in the waste into hydrogen and acid gas in an oxygen-free environment, and the metal in the waste is melted and discharged from the body for recycling. After the inorganic matter is melted, it is discharged from the body and cooled into a plasma pyrolysis reactor that resembles a lava glass body. Background technique [0002] With the rapid development of modern society, environmental pollution is becoming more and more serious. Many substances in factories are harmful or poisonous, especially high-risk electronic waste generated by high-tech technology. Simple incineration or burial cannot be used, otherwise it will be A large amount of dioxin-like substances are produced, including toxic garbage fly ash and various toxic substances such as Pb, Cd, and Hg in the seepage formation, which will seriously...
