Description
Technical field
The present invention relates to a kind of Spelter smelting kiln, belong to technical field of non-ferrous metallurgy.
Background technology
The smelting process of metallic zinc mainly is divided into two kinds of wet method and pyrogenic processes.The investment of hydrometallurgy is huge, the wastewater treatment difficulty, and strong to material choice, area occupied is large, and investment is large, and the consumption chemical adjuvant is many.Pyrometallurgical smelting has perpendicular tank smelting, blast furnace smelting and electrosmelting etc., has all that unit output investment is large, production cost is high, energy consumption is high, to shortcomings such as material choice are strong, and equipment is complicated, and floor space is large.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of low cost of manufacture, second-generation crude zinc smelting kiln that production efficiency is high, simple in structure, thereby overcomes the deficiencies in the prior art.
For solving the problems of the technologies described above, the present invention adopts following technical scheme: second-generation crude zinc smelting kiln.Its formation comprises the kiln body, at the kiln body opening for feed, air outlet, liquid outlet and slag notch is arranged; In the kiln body, be provided with the zinc vapor condensing section and smelt section; In the zinc vapor condensing section water wheel type condenser is installed, in the smelting section electric heating body is installed.
In the above-mentioned second-generation crude zinc smelting kiln, at opening for feed bell hourglass feeding device is installed.
In the aforesaid second-generation crude zinc smelting kiln, the pressure controlling device is installed in the air outlet.
In the aforesaid second-generation crude zinc smelting kiln, slag notch connects sedimentation type deslagging vertical shaft.
In the aforesaid second-generation crude zinc smelting kiln, electric heating body connection slip ring formula electricity gatherer.
In the aforesaid second-generation crude zinc smelting kiln, electric heating body is to be embedded on the kiln body inwall.
Beneficial effect of the present invention: the present invention be directed to the applicant is the improvement product of " a kind of Spelter smelting kiln " in the denomination of invention of application on September 29th, 2009, has following characteristics: (1), employing water wheel type condenser.The many groups of employing water wheel type lifting gears are carried zinc liquid above circumference and are had a down dip in the water wheel type condenser, form the zinc curtain of rain zinc fume is carried out condensation, accelerate condensing rate, increase the smelting amount, and zinc liquid travels forward through the liner in the middle of the water wheel type condenser, fall behind under the zinc liquid and rely on again the obliquity of kiln body self to move backward, zinc gray, the blue powder that will be attached to simultaneously zinc liquid and condenser wall and periphery are taken back and are smelted section, again smelt.2, adopt sliding ring type electricity gatherer.Directly or indirectly material is heated smelting in the smelting section by electric heating body, its thermosteresis is little, heat utilization ratio is high, energy consumption is low.Because heating element is to be embedded in the kiln body of rotation, therefore adopt sliding ring type electricity gatherer that power supply is introduced in the electric heating body, make the electric heating body heating finish pyrotic smelting, this movable electrically conducting manner first Application is in the inner heating of rotary kiln, and power is large, electric current is large, voltage is high.3, it is reinforced that material adopts bell hourglass formula.The reinforced bell hourglass feeding device that adopts, not only can guarantee the stopping property of charging system but also can reach at the uniform velocity reinforced purpose, can when reinforced, guarantee the resistance to air loss of material in kiln, and the reinforced continuous and homogeneity of assurance, because bell hourglass feeding device is to carry out the nature controllable type by hourglass to let out reinforced, need not to use any power, reduced the energy consumption of traditional mechanical loading, saved cost.4, kiln inner pressure is regulated and control.Because vapour outlet and drying materials section respectively have an outlet in the stove of smelting kiln, for avoiding causing the furnace pressure skewness, by setting pressure regulation device on the air outlet of kiln body, can realize automatic or manual control and regulating stove internal pressure, make furnace pressure be tending towards all the time the slight positive pressure state that equates everywhere, thereby the condensation of assurance zinc fume and material is unimpeded.5, adopt sedimentation type deslagging vertical shaft.Slag notch connects sedimentation type deslagging vertical shaft, the waste residue that produces after material is smelted drains into by slag notch in the sedimentation type deslagging vertical shaft of kiln tail to be piled up and gradually cooling, foot at sedimentation type deslagging vertical shaft is provided with the pressure sensitive device, when waste residue is accumulated to setting weight, deslagging device by sedimentation type deslagging vertical shaft bottom is external with the waste residue output furnace, has not only guaranteed the stopping property of body of heater but also waste residue can have been discharged smoothly.
The present invention with charging, pyrotic smelting, condensation, put in the smelting kiln that zinc and deslagging all concentrate on a rotation and finish, dispel the heat and be combined the purpose that reaches the condensation zinc fume with the zinc curtain of rain by the rotation of water wheel type condenser, condensation effect is good, and waste gas is few, ash is few, and direct yield is high.Compare first-generation product, structure of the present invention is simpler, and treatment capacity is larger, and smelting speed is faster, and production efficiency is higher, and more convenient operation, manufacturing cost are lower.Because pyrotic smelting and condensation are all carried out in the smelting kiln of a rotation, so material loss is little, the rate of recovery is high and heating material is balanced, energy consumption is low, easy to operate.Because energy consumption is low, specific investment is few, the rate of recovery is high, can use low-cost raw material, so production cost is also very low.
The present invention meets the requirement of environmental protection, energy-conservation, recycling economy, both has been fit to crude zinc smelting, also is fit to other non-ferrous metal metallurgies, all use the present invention carry out other non-ferrous metal metallurgies all within protection scope of the present invention.
