Poisonous waste treating method and special apparatus

Abstract

The present invention relates to poisonous waste treating method and apparatus, and belongs to the field of waste treating technology. The poisonous waste treating apparatus is plasma apparatus comprising a furnace body, a main graphite electrode and an auxiliary graphite electrode connected to the cover of the furnace body, carrier gas supplier connected to the main graphite electrode, a feeder, a vitreous body exhausting heat pump, a metal melt heat pump, a crucible inside the furnace body, a lower electrode in the bottom of the furnace body, a liquid level sensor connected to the sensor controller, and a tail gas exhausting system connected to the furnace body. It is used in treating polychlorinated biphenyl and other high dangerous waste through instantaneous high temperature, and has no secondary pollution, capacity of recovering high energy gas, and capacity of recovering metals.

Description

technical field

[0001] The invention relates to a method and a special device for treating waste, in particular to a method and a special device for treating toxic and harmful waste. Background technique

[0002] With the rapid development of modern society, environmental pollution is increasing day by day. Many of the synthetic chemical substances are harmful or toxic, especially the high-risk electronic waste generated under high-tech conditions, which cannot be simply incinerated or buried. Otherwise, a large amount of dioxin (Dioxin)-like substances, highly toxic garbage fly ash, and various toxic substances such as Pb, Cd, and Hg in the seepage formation will be produced, seriously polluting the environment. In other words, the traditional landfill and incineration methods have been severely challenged due to secondary pollution, migration effects and low efficiency, especially the production of more toxic polychlorinated dibenzodioxins (PCDDs) during the incineration p...
