Problems solved by technology

[0002] At present, the fuel used for the roasting of the belt sintering machine in the lead smelting industry is mostly heavy oil. Due to the serious pollution of heavy oil, and because the combustion effect is greatly affected by the "atomization" situation, the fire of this fuel has been unstable for many times during use. The phenomenon of oil and flame failure greatly affects the effect of sintering and roasting. With the continuous rise of the international crude oil market price, the domestic oil market has been rising all the way. The problem of price and procurement has become a difficult problem for most enterprises.

Embodiment Construction

[0008] Such as figure 1 As shown, the present invention selects coal gas to ignite and burn the materials on the lead sintering machine, and keeps the gas supply continuous and stable. Coal gas is produced by the gas generator 1, and the gas produced by the gas generator 1 is sent to the cyclone dust collector 3 through the gas pipeline 2. After the dust is removed by the cyclone dust collector 3, the gas is sent to the gas branch pipe 6 through the gas pipeline 2, and the combustion-supporting air Enter the combustion-supporting air branch pipe 7 through the combustion-supporting air pipe 5, the gas branch pipe 6 and the combustion-supporting air branch pipe 7 pass through, and then connect to the furnace of the ignition furnace 4 through the gas burner, and the combustion-supporting air and the gas are fully mixed and enter the point through the gas burner Furnace hearth for combustion. The volume ratio of the combustion-supporting air and the gas is 1:1. The gas and the co...

Abstract

Under stable supply, coal gas is fired to burn materiel on lead sinter machine. Through gas pipe, coal gas generated from gas generator is entered to cyclone dust collector. Through gas pipe, dust removed coal gas is entered to branch pipe. Through air pipe, comburant air enters into branch pipe. After branch pipe for coal gas and branch pipe for comburant air are connected to each other, and led to burner, where gas and air are mixed fully in volume ration being about 1:1. Through the burner, mixed gas burns in firebox of ignition furnace. Advantages are: lowering cost by using gas to replace heavy oil, better controlling fire behavior, and good effect for baking materiel.

Description

Technical field: [0001] The invention belongs to the technical field of lead smelting, and in particular relates to a belt sintering method for roasting by using coal gas on the belt sintering machine. Background technique: [0002] At present, the fuel used for the roasting of the belt sintering machine in the lead smelting industry is mostly heavy oil. Due to the serious pollution of heavy oil, and because the combustion effect is greatly affected by the "atomization" situation, the fire of this fuel has been unstable for many times during use. The phenomenon of oil and flame failure greatly affects the effect of sintering and roasting. With the continuous rise of the international crude oil market price, the domestic oil market has been rising all the way. The problem of price and procurement has become a problem faced by most enterprises. Invention content: [0003] The object of the present invention is to overcome the deficiencies in the prior art and provide a sinte...
