Abstract
Electric-heating bottom-blowing reducing direct antimony-smelting engineering equipment consists of a dynamic reducing furnace and a static electric heating furnace, a fall is formed between the two furnaces, the dynamic reducing furnace is a cylindrical reducing furnace which can rotate around a horizontal central axis, and gas can be inflated from the bottom or the side part of the dynamic reducing furnace for stirring materials in the furnace, so as to increase the chemical reaction area of the materials in the furnace and increase the reaction speed to save energy; and circular arcs are arranged at the two ends of the electric heating furnace, and electrodes are fixed at the upper part of the electric heating furnace to heat or cool the stored melted materials by electricity at any time, so that the chemical reaction and the slag antimony separation which are not finished in the dynamic reducing furnace can be performed on the melted materials at a proper temperature. After adoption of the technical scheme, compared with antimony smelting in a reverberatory furnace and a blast furnace system, the electric-heating bottom-blowing reducing direct antimony-smelting engineering equipment has the advantages that a set of smelting equipment can be saved; the investment can be saved by 30-50%; energy is saved by 30%; the working environment is good; the mechanical degree is high; the continuous production is strong; and the like.
Description
One, technical field
This equipment is the antimony regulus engineering equipment that is applied to the nonferrous smelting industry.
Two, background technology
It is improvement to traditional stibium smelting technology and equipment that direct antimony regulus engineering equipment is reduced in the electric heating bottom blowing;
China mostly adopts reverberatory furnace-blast furnace system antimony regulus; Reverberatory furnace in the process of producing because the restriction of the type of furnace, material loading is skimmed, and slags tap, go out that antimony can not adopt mechanize so that flue dust and dust fly upward the pollution Working environment everywhere, the interior accumulation of material adding stove is in heaps and do not have whipping appts that material is evenly spread out, is difficult to carry out chemical reaction, thereby increases the reaction times of material, increase so burning amount of fuel, increase the fume amount in the flue gas, increase the dust collecting system workload, the power consumption of corresponding increase dust collecting system; The blast furnace smelting system also exists above-mentioned reverberatory furnace stopping property poor, work under bad environment, in the stove material reaction time long, energy consumption height, the drawback such as mechanization degree is low; Every equipment all needs air feed separately in reverberatory furnace-blast furnace system antimony regulus process, and feed for fuel system, causes overlapping investment, and floor space is huge, and cost of investment is high, and the feature of environmental protection is poor, is smelting technology and the system that eliminates in the future.
Three, summary of the invention
For the problems referred to above, according to national industrial policies, develop a circular economy, energy-saving and emission-reduction, protection of the environment, the following technical scheme of special proposition:
Direct antimony regulus engineering equipment is reduced in the electric heating bottom blowing, comprises dynamic reduction furnace and static electrothermal oven, and horizontal drop is arranged between the two, is formed by connecting by chute.
Dynamically reduction furnace has the round tube type body of heater of horizontal center line axis rotation, disposes gear mechanism electric driver and rolling ring on the body of heater, and support roller group and base support are arranged under the gear ring, body of heater.
Bottom or the sidepiece of body of heater dispose insufflator, and pressurized gas is sprayed into body of heater.
The top of body of heater is provided with charging opening, smoke outlet, and body of heater end bottom is provided with slag notch.
Body of heater and an end are provided with combustion supporting burner.
Electrothermal oven top is provided with electrode and power distribution unit.
The electrothermal oven sidepiece is provided with the slag notch of drop, goes out the antimony mouth.
Adopt technique scheme, can realize that a cover electric heating bottom blowing reduces direct antimony regulus equipment and can replace reverberatory furnace, blast furnace two cover smelting systems, can save cover melting equipment and an occupation of land, with reverberatory furnace, blast furnace system antimony regulus is compared, and 30-40% is saved in investment, production cost reduces 30%, the advantages such as building ring is quiet good, and mechanization degree is high, and continuous production is strong, being the smelting equipment of antimony smelting industry first-selection, also is the smelting equipment system of national encourage growth.
