The operation principle of the utility model：
The utility model belongs to zinc abstraction technology, and technique is inserts electrodes into liquid molten body（That is slag）In, it relies on
The micro- electric arc formed on electrode and slag interface and the double action of melting bulk resistor, make electric energy be converted into thermal energy, by zinc ore
Fusing generates zinc oxide gas, and reduction reaction occurs with coke, generates zinc fume, is cooled down through lead-splash condenser device, forms lead
Zinc mixed liquor obtains simple metal zinc through separation, rectifying, and lead liquid is back to condenser recycling, this equipment has energy saving, ring
Guarantor, safe and reliable, with good investment, the construction period is short, connects graphite electrode using 32000KVA transformers, produces 100000 tons or more per year,
The material containing more than 20% zinc can be directly handled, complicated raw material can be handled（Contain lead, copper, tin, nickel, titanium, iron etc.）, and can be enriched with
With being recycled in scum and lead bullion, recovery rate of valuable metals is high, and the direct yield of zinc is more than 90%, and overall recovery is more than 98%, slag
Within zinc 1%.
The technological core of the utility model：It is safe by the effective expanding production of design of horizontal separate unit electric furnace, lead to
The design for crossing lead discharging mouth effectively excludes the lead liquid of electric furnace inner accumulation, since Horizontal electric furnace body type is huge, various materials
Coefficient of thermal expansion between material is different, can cause to squeeze or shrink during being heated or cooled, that stitches in expansion is designed with
Effect solves the problems, such as this, by the design stitched in expansion, the surplus that various expansion or shrinkage generate is compensated, lead rain
The design of condenser device effectively solves the heat transferring medium of a large amount of zinc cooling requireds, the effective enhancing lead of design for the slot that cools down
It recycles.
