Plasma melting and cracking furnace

Abstract

The invention discloses a plasma melting and cracking furnace. The plasma melting and cracking furnace comprises a power supply, a bracket, a receiving mould, a crucible, a furnace lid, plasma torch generating devices, a heat exchanger, a first-stage settling and purifying room, a second-stage electrostatic purifying room and a third-stage filtering and purifying room, wherein the plasma torch generating devices are arranged on the furnace lid. According to the plasma melting and cracking furnace disclosed by the invention, industrial garbage can be effectively melted and cracked, waste gas generated by combustion is recycled after being purified, waste is taken as a building raw material, pollution on environment is greatly reduced, and waste of resources is reduced, so that the plasma melting and cracking furnace saves more energy and is environmentally friendlier.

Description

technical field [0001] The invention belongs to the technical field of machinery, in particular to a plasma melting and cracking furnace. Background technique [0002] At present, medical waste and industrial hazardous waste are the most serious in my country. These waste incinerations generally still use traditional gas and oil combustion methods, and the incinerators used in this gas and oil combustion method are treated because the temperature in the furnace is not high (generally lower than 900 °C, but the actual situation only operates below 700 °C ), it is easy to produce dioxins (600℃~800℃), and more than one-third of combustibles and some bacteria remain in the burning garbage ash. The leaching out of the ground will still cause secondary pollution to the environment. After oozing out, it will affect the soil, water quality, people and animals, and the infection will spread rapidly after drinking water. Even if packaging is used for centralized treatment, it is ver...

AI Technical Summary

Problems solved by technology

The incineration of these wastes generally still adopts the traditional gas and oil combustion method, and the incinerator treatment adopted by this gas and oil combustion method is not high because the temperature in the furnace is not high (generally lower than 900°C, but the actual situation only operates below 700°C) ), it is very easy to produce dioxins (600°C~800°C), and more than one-third of the combustibles and some bacteria still remain in the burned garbage ash, and the burned garbage ash is used as domestic garbage. The precipitation on the ground will still cause secondary pollution to the environment. After seeping out, it will affect the soil and water quality. People, animals, and drinking water will quickly spread the infection

Even if it is packaged for centralized treatment, it is easy to be distributed during transportation in urban areas, and it is easy to pollute the environment again

Most of the plasma melting and cracking furnaces on the market are equipped with an ion torch generator, which can only cut or melt and crack garbage in a small area, and blow the garbage away under the action of high-pressure gas, and cannot ideally melt all the garbage. cleavage
