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
The present invention relates to for the treatment of the pyrometallurgical smelting stove containing materials such as non-ferrous metal material, solid waste.
Background technology
The technical development of immersed top-blown smelting technology has been very ripe technology so far, but due to immersed top-blown stove employing top smoke structure, cause whole stove bulky, refractory consumption rate is large, and supporting factory building is high, and investment is large.In addition, due to the mode of top smoke structure, after flue gas cooling infrastructure can only frame on stove, bulk flue dust is fallen in molten bath, causes sharply lower the temperature to molten bath, operates very unstable.Cooling water inside cooling infrastructure is easy to drain in stove, brings a lot of harm to refractory material and production safety.
All top blast stoves adopt top smoke now, and due to top smoke structure, shaft is amplified gradually from middle part, complex structure, and refractory consumption rate is large, and supporting factory building is high, and investment is large.
Summary of the invention
The present invention is directed to the deficiencies in the prior art, provide a kind of structure simple, easily manufactured, reduced investment, effectively prevents cooling water from returning leakage, and flue dust falls the side formula smoke top blast stove into molten bath after rise.
For realizing the object of the invention, provide following technical scheme: side formula smoke top blast stove, comprise the furnace top cover on cylindric vertically body of heater, body of heater top, body of heater is made up of the steel furnace shell of fire brick lining and outer surface, and body of heater bottom is provided with grate, and grate is mounted on body of heater basis, it is characterized in that outlet flue is arranged on the sidewall of body of heater nearly top, vertically with body of heater arrange, described outlet flue cross section is square, and outlet flue port protrudes sidewall of the furnace body.
As preferably, the height h >=6000mm of the highest of outlet flue most bottom surface distance bottom of furnace body fire brick lining.
As preferably, fire brick lining diameter D in the distance L >=body of heater of outlet flue outermost face distance body of heater center line, as preferably, fire brick lining diameter 2D in the body of heater of the distance L≤twice of outlet flue outermost face distance body of heater center line.
As preferably, outlet flue height dimension H:D/4≤H≤2D, D are fire brick lining diameter in body of heater.
As preferably, outlet flue width dimensions B:D/8≤B≤2D, D are fire brick lining diameter in body of heater.
As preferably, outlet flue both sides and top steel lining structure of refractory, bottom arranges resistance and spatters plate, and resistance is spattered plate and adopted Copper Water Jacket.
Beneficial effect of the present invention: outlet flue is arranged at sidewall of the furnace body by the present invention, flue gas facility is directly connected on stove outside below, be separated with stove factory building with stove, efficiently solve the problem that the portion's smoke of immersed top-blown furnace roof brings, structure is simple, easily manufactured, reduced investment, effectively prevent cooling water from returning leakage, flue dust falls after rise into molten bath.
