Abstract

The invention relates to a vertical flame channel and hot bed-connected type powder material continuous melting furnace. The vertical flame channel and heating bed-connected type powder material continuous melting furnace comprises a steel shell; a weighing silo is arranged on the top of the steel shell; the material discharging opening of the weighing silo is provided with a horizontal type spiral constant feeder; the bottom of the steel shell is provided with a water sealed slag remover; a continuous melting furnace is arranged in steel shell; a flame retardant layer and a thermal insulation layer are sequentially arranged between the outer surface of the continuous melting furnace and the inner surface of the steel shell; a vertical flame channel and a hot bed are arranged in the continuous melting furnace; the bottom of the vertical flame channel is communicated with the front portion of the hot bed; the top of the vertical flame channel is provided with a first combustor and a blanking opening; the blanking opening is communicated with the material discharging opening of the horizontal type spiral constant feeder; the joint of the vertical flame channel and the hot bed is provided with second combustors; the rear side of the bottom of the hot bed is provided with a slag out-flow opening; and the slag out-flow opening is in butt joint with the feeding opening of the water sealed slag remover. The vertical flame channel and hot bed-connected type powder material continuous melting furnace of the invention has the advantages of low investment, small size, convenient manipulation, low running cost and the like.

Description

technical field [0001] The invention relates to a melting furnace, in particular to a continuous melting furnace for powdered materials with a vertical flame channel connected to a heated bed. Background technique [0002] With the promotion of incineration technology in domestic waste and hazardous waste treatment, the amount of fly ash and hazardous waste slag produced by incineration is increasing year by year. At present, my country mainly transports them to safe landfills after simple treatment or uses stockpiling and simple cement solidification The way of transporting them to landfills for landfilling occupies land resources, there is a risk of secondary pollution, and the cost is high. Heavy metal sludge produced by electroplating and automobile painting, metallurgy, IT, and comprehensive utilization of heavy metal sludge has the characteristics of easy accumulation, instability, and easy loss. If it is not properly treated, it will cause surface water, soil, and grou...
