Abstract
The energy-saving zinc rectifying and smelting process includes setting one combustion chamber with one lead column in a rectifying furnace, heating the lead column inside the combustion chamber with high temperature gas, heating one cadmium column with the high temperature gas after heating the lead column, and leading the high temperature gas to the zinc melting furnace. The zinc rectifying furnace for rectifying and smelting zinc includes one lead column, one cadmium column, one zinc melting furnace, one condenser, one lead column feeder, one cadmium column feeder, and one combustion chamber communicated to the cadmium column feeder and the combustion chamber. The improved smelting process and apparatus has high production efficiency, low power consumption, low production cost and reduced discharged dust amount.
Description
Technical field
The present invention relates to a kind of pyrometallurgy of zinc method and apparatus, particularly relate to a kind of zinc rectificating method and zinc re-distillation furnace.
Background technology
The zinc re-distillation furnace principal mode that acts as a fuel with coal or coal gas in zinc concentrate is, plumbous tower, cadmium tower and zinc smelting furnace each have the combustion chamber of oneself respectively and burn coal or coal gas separately, this zinc metallurgy form has the combustion chamber more than 3, not connected, combustion exhaust separately adds warm air by special Heat Room or heat exchanger channels or coal gas is input to the combustion chamber once more.Though this zinc metallurgy method of independent combustion chamber of utilizing can reach plumbous tower, cadmium tower and the desired temperature of each stove of zinc smelting furnace on request, the combustion chamber is many, and combustion exhaust utilizes insufficient, and it is higher to consume energy.
Summary of the invention
The objective of the invention is to, a kind of zinc rectificating method and used zinc re-distillation furnace are provided.The present invention can enhance productivity, cut down the consumption of energy and reduce production cost.
Technical scheme of the present invention.A kind of zinc rectificating method, characteristics are: a combustion chamber only is set in the rectifying furnace, and plumbous tower places the combustion chamber, and the high-temperature gas in the combustion chamber enters the cadmium tower after plumbous tower is heated, enter the zinc smelting furnace after the cadmium tower being heated again.
The zinc re-distillation furnace that above-mentioned zinc rectificating method is used, structure comprises plumbous tower 1, cadmium tower 3, zinc smelting furnace 4, condenser 7, plumbous tower feeder 8 and cadmium tower feeder 9, also comprise a combustion chamber 2, plumbous tower 1 places combustion chamber 2, and lead to zinc smelting furnace 4 after leading to cadmium tower 3 combustion chamber 2 again.
The zinc re-distillation furnace that above-mentioned zinc rectificating method is used is: the smoke outlet at zinc smelting furnace 4 is provided with heat exchanger 6.
Compare with original technology, the present invention has improved production efficiency, reduced energy consumption and has reduced production cost by the improvement to smelting process and equipment.The present invention and original smelting mode relatively have good energy-saving effect, and the technico-economical comparison contrast of the two sees Table 1.
Table 1
Because the smoke-uptake lengthening, the Dust Capacity of discharge reduces, and application of the present invention can also improve Working environment and minimizing is polluted.The present invention has good economic benefits and social benefit, and the smelting that can be used for smart zinc need be carried out in the Metal smelting of high low temperature stagewise operation with other.
Description of drawings
Fig. 1 is a structural representation of the present invention;
Embodiment
Embodiments of the invention.The zinc rectificating method, this method is: a combustion chamber only is set in the rectifying furnace, and plumbous tower places the combustion chamber, and the high-temperature gas in the combustion chamber enters the cadmium tower after plumbous tower is heated, enter the zinc smelting furnace after the cadmium tower being heated again.
The zinc re-distillation furnace that zinc rectificating method shown in Figure 1 is used, structure comprises plumbous tower 1, cadmium tower 3, zinc smelting furnace 4, condenser 7, plumbous tower feeder 8 and cadmium tower feeder 9, it is characterized in that: also comprise a combustion chamber 2, plumbous tower 1 places combustion chamber 2, lead to zinc smelting furnace 4 after leading to cadmium tower 3 combustion chamber 2 again, is provided with heat exchanger 6 at the smoke outlet of zinc smelting furnace 4.
The present invention is by adopting a combustion chamber 2 to finish whole zinc rectifying, directly carry out heat supply with the 2 pairs of plumbous towers 1 in combustion chamber, and as shown in Figure 1, hollow arrow is represented the flow of flue gas direction, and filled arrows is represented the Flow of Goods and Materials direction.The startup thermal source of a fusing crude zinc is arranged on zinc smelting furnace 4, when beginning to produce smart zinc, open the startup thermal source earlier, the solid-state crude zinc in the zinc smelting furnace 4 is molten into liquid state, can close the startup thermal source; Also can directly use combustion chamber 2 startup work.Liquid crude zinc is sent in the plumbous tower 1 by plumbous tower feeder 8, starting combustion chamber 2 separates the galvanized iron in the crude zinc by plumbous tower 1, crude zinc after the separation enters condenser 7 cooling back and sends in the cadmium tower 3 by cadmium tower feeder 9, and the high-temperature flue gas that combustion chamber 2 produces is introduced in cadmium tower 3 and finishes separating of zinc and cadmium; The smart zinc of removing cadmium enters smart zinc pond.The flue gas that to introduce again every tower 3 is incorporated into zinc smelting furnace 4 places, makes the crude zinc in the zinc smelting furnace 4 be molten into liquid state.Liquid crude zinc in the zinc smelting furnace 4 is sent in the plumbous tower 1 by plumbous tower feeder 8 again, makes zinc re-distillation furnace carry out continuous production.The flue gas of zinc smelting furnace 4 discharges by exhanst gas outlet, and discharged flue gas adds warm air or coal gas by heat exchanger 6 or Heat Room, and the air or the coal gas of heating are input to combustion chamber 2 again, further saves the energy with this.This routine described combustion chamber 2 is to be fuel to burn gas or fuel oil, and its is again a heating chamber simultaneously; If use coal, the combustion chamber can be considered heating chamber, passes through another combustion chamber earlier with coal combustion, again the high-temperature gas that produces is incorporated into combustion chamber 2.
Behind utilization the present invention, production technique is identical with existing smart zinc production technique.
