Silicon carbide environmentally-friendly smelting process and device thereof

Abstract

The invention relates to a silicon carbide environmentally-friendly smelting process which is characterized by adopting underground smelting, overground smoke purification utilization and control by virtue of an overground computer monitoring system. The invention also relates to a silicon carbide environmentally-friendly smelting device which is characterized by comprising a silicon carbide underground smelting workshop, an underground closed type silicon carbide kiln, an underground closed type silicon carbide kiln top negative hot pressure smoke acquiring louver device, an explosion-proof screen and a camera, a hot smoke acquirer at the bottom of the underground silicon carbide kiln, a movable explosion-proof wall, a movable explosion-proof wall overground smoke purifying and distributing chamber, a carbon dioxide acquirer and a dry ice device, a hydrogen sulphide and sulphur dioxide reaction lime pond, a precipitated water circulating recycling system, a carbon monoxide acquirer and a boiler, a methyl mercaptan and combustible gas acquirer, an overground travelling car and an overground computer monitoring system, an overground water supply system and a hot smoke induced draught system. By adopting the method provided by the invention, components in the hot smoke of silicon carbide are purified and decomposed, and neutralization and utilization are carried out, thus the hot smoke is completely environmentally-friendly.

Description

technical field [0001] The invention relates to an environment-friendly silicon carbide smelting process, in particular to an environment-friendly silicon carbide smelting method and a device for silicon carbide underground smelting, above-ground fume purification and utilization, and above-ground smelting monitoring. Background technique [0002] The existing silicon carbide production is mainly smelting with workshops on the ground and open-air smelting without workshops. Its harmful fumes fill the sky and waft around. Due to the smoke and dust permeating the high altitude, people cannot effectively collect the hot smoke produced by silicon carbide smelting, thus making the silicon carbide industry a highly polluting industry. In order to solve the environmental problem of high smoke and dust pollution in silicon carbide production, people have proposed to use underground smelting methods, but there are unsolvable technical problems in the underground production of silico...
