The invention discloses a plasma melting and solidification disposal device for industrial dangerous waste. The plasma melting and solidification disposal device comprises a raw material drying and conveying device, a melting device, a plasma spray gun, a heat exchanger and a smoke disposal device. The outlet of the raw material drying and conveying device is connected with the inlet of the melting device. The plasma spray gun is installed on the melting device. The outlet of the melting device is connected with the inlet of the heat exchanger. The outlet of the heat exchanger is connected with the inlet of the smoke disposal device. According to the plasma melting and solidification disposal device, through cooperation of the raw material drying and conveying device, the melting device, the plasma spray gun, the heat exchanger and the smoke disposal device, waste can be rapidly disposed, and the problem that a traditional solid waste disposal device is low in efficiency is solved; through the arrangement of the plasma spray gun, a curing reaction can be carried out stably, and the defect that the traditional solid waste disposal device is poor in stability is overcome; and through the arrangement of the heat exchanger and the smoke disposal device, emission requirements are met, and the problem that the traditional solid waste disposal device is severe in pollution is solved.
Description
technical field [0001] The invention relates to a plasma melting and solidification treatment device for industrial hazardous waste, especially suitable for bottom slag and fly ash produced in waste treatment plants, denitrification catalysts in power plants, tar-like waste produced in nonferrous metal pyrometallurgy, and chromium produced in metal chromium smelting. The leaching slag, waste activated carbon and filter cake produced by waste gas treatment belong to the technical field of solid waste treatment. Background technique [0002] With the rapid development of industrialization, the generation of urban industrial hazardous waste is increasing. It is estimated that the annual production of hazardous waste in the world is 330 million tons. Due to the serious pollution and potential serious damage caused by hazardous waste Influenced by industrial developed countries, hazardous waste has been called "political waste", and the public is very sensitive to the issue of ha...
