Lateral smoke discharge and top blowing furnace

Abstract

A lateral smoke discharge and top blowing furnace is used as a fire smelting furnace for processing materials containing non-ferrous metal, solid waste and other materials. Heating and smelting are conducted through an immersed type furnace hearth smelting spray gun for the smelting furnace, and smoke is discharged from one side of the furnace. The furnace comprises a cylindrical vertical furnace body and a furnace top cover at the top end of the furnace body. The furnace body is composed of a fire brick lining and a steel furnace shell on the outer surface. A furnace framework is arranged at the bottom end of the furnace body and fixedly installed on a furnace body foundation. A smoke outlet is formed in the side wall, close to the top end, of the furnace body and perpendicular to the furnace body. The smoke outlet has a square section. The port of the smoke outlet protrudes out of the side wall of the furnace body. The upper side and the lower side of the lateral smoke outlet and top blowing furnace are the same in size, and the lateral smoke discharge and top blowing furnace is simple in structure, convenient to manufacture and capable of saving investment.

Description

technical field [0001] The invention relates to a pyromelting furnace for treating materials containing ferrous metals, solid waste and the like. Background technique [0002] The submerged top-blowing smelting process technology has been a very mature technology so far, but because the submerged top-blowing furnace adopts the top smoke outlet structure, the entire furnace is bulky, the consumption of refractory materials is large, the supporting workshop is high, and the investment is large. In addition, due to the way of the smoke outlet structure at the top, the flue gas cooling facility at the back can only be placed on the furnace, and large pieces of smoke fall into the molten pool, causing a sharp drop in temperature of the molten pool, and the operation is very unstable. The cooling water in the cooling facility is easy to leak into the furnace, which brings many hazards to refractory materials and production safety.

AI Technical Summary

Problems solved by technology

[0002] The submerged top-blowing smelting process technology has been a very mature technology so far, but because the submerged top-blowing furnace adopts the top smoke outlet structure, the entire furnace is bulky, the consumption of refractory materials is large, the supporting workshop is high, and the investment is large.

In addition, due to the way of the smoke outlet structure at the top, the flue gas cooling facility at the back can only be placed on the furnace, and large pieces of smoke and dust fall into the molten pool, causing a sharp drop in temperature of the molten pool, and the operation is very unstable.

The cooling water in the cooling facility is easy to leak into the furnace, which brings many hazards to refractory materials and production safety

[0003] Nowadays, all top-blown furnaces use top-blown smoke. Due to the top-blown smoke structure, the furnace body gradually increases in size from the middle, with complex structures, large consumption of refractory materials, high supporting workshops, and large investment.
