Embodiment 1

[0023] Embodiment 1: The device has a plasma device, a carrier fluid gas supplier, a main graphite electrode, an auxiliary graphite electrode, a feeder, a furnace body, a crucible, a glass discharge heat pump, a polymetallic enriched body melt heat pump, a liquid level sensor, and a sensor The controller and exhaust gas discharge system, the plasma device, the main graphite electrode and the auxiliary graphite electrode are connected to the furnace cover of the furnace body, the carrier fluid gas supplier is connected to the main graphite electrode, the feeder is located on the upper side of the furnace body, and the glass body discharges the heat pump Located on the other side of the furnace body, the metal-enriched body melt heat pump is located at the bottom of the furnace body, the crucible is located in the furnace body, the liquid level sensor is located at the upper end of the crucible, and is connected to the sensor controller, and the exhaust gas discharge system is con...

Embodiment 2

[0047] Example 2 The fly ash produced by the domestic waste incinerator contains a large amount of highly toxic dioxin and other components, and is fed into the plasma arc area through a feeder, and is rapidly melted at a temperature of 1300°C, and the highly toxic organic matter is instantly cracked and environmentally friendly. The inorganic small molecules, through the exhaust gas purification treatment, are emptied up to the standard. Turn on the power supply of the vitreous body discharge heat pump and the metal-enriched body melt heat pump, and the metal melt flows out of the furnace body after being heated by the metal-enriched body melt heat pump, and the heating temperature is 1300°C; ℃; the waste gas generated during pyrolysis and melting is discharged from the furnace body through the exhaust hole of the furnace body through the exhaust system, and the exhaust gas is discharged from the exhaust system through the tail gas secondary treatment room at 1250°C for high t...

Embodiment 3

[0048]Example 3: The waste Pt-containing noble metal catalysts produced in the petrochemical industry are sent into the plasma arc area together with the additives. At a temperature of 3000 ° C, the catalyst carrier Al 2 o 3 With CaO and SiO in additives 2 and other substances are vitrified together, discharged from the furnace body, and precious metals such as Pt and metal absorbers such as Cu are melted together to form a metal melt and discharged out of the furnace, which can be directly used to recover precious metals such as Pt. Turn on the power supply of the vitreous discharge heat pump and the metal-enriched body melt heat pump, and the metal melt flows out of the furnace body after being heated by the metal-enriched body melt heat pump, and the heating temperature is 1500°C; ℃; the exhaust gas produced during pyrolysis and melting is discharged from the furnace body through the exhaust hole of the furnace body through the exhaust system, and the exhaust gas is discha...

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...
