A kind of fuming furnace for the treatment of zinc leaching residue Technical field The utility model relates to a kind of fuming furnace, specially refers to a kind of fuming furnace for the treatment of zinc leaching residue. Background technology Fuming furnace is a kind of high temperature fuming furnace for the treatment of chats, slag, leached mud, small-sized fuming furnace equipment is circular or oval-shaped, medium-sized and large-scale fuming furnace equipment is rectangle, the basic element of character that forms fuming furnace is cooling water tank, cooling water tank has furnace bottom cooling water tank, cupola well cooling water tank, furnace wall cooling water tank, furnace roof cooling water tank, water tank is made with general steel plate, and the thickness of steel plate is 10mm～16mm.The furnace bottom of tradition fuming furnace fuming furnace is lined with the refractory brick of a layer thickness 200mm～350mm, and cupola well is not to be lined with refractory brick, and hot water or the low-pressure steam of furnace wall cooling water tank output do not enter the boiler pipe network, and be directly emptying. Fuming furnace is a kind of high temperature fuming furnace, feature from material and burning, belong to high temperature molten bath melting equipment, in melting process, the airflow that material is sprayed into stirs, form the violent motion of seething, the exchange of material and heat fast and fully, therefore, it is large that fuming furnace has the siege ability, the high characteristics of volatilization efficient are widely used in extraction and the enrichment of lower boiling metal and lower boiling metal oxide, such as the blowing of the medium tin ore in the tin smelting process, the rich slag sulfiding volatilization of tin, the dilution volatilization of blast furnace lead skim, the reduction volatilization of zinc leaching residue etc. The tradition fuming furnace, the siege ability is large, the high advantage of volatilization efficient although have, but because traditional fuming furnace equipment simply is comprised of a plurality of water tanks, there is obvious shortcoming: at first, because the cupola well cooling water tank does not have the refractory brick protection, the strenuous exercise of material in the cupola well, directly the cupola well cooling water tank is impacted and rub, this impact and friction are very large to the infringement of cupola well cooling water tank, and corrode is very fast, and the life cycle of cupola well water tank only has 3～6 months; Secondly, because cupola well does not have inner lining refractory block, the strenuous exercise of material in the cupola well, the heat of material itself is passed to the cupola well cooling water tank fast, make the temperature fast-descending of material self, this need to replenish a large amount of heats just can keep the interior thermal equilibrium of stove, therefore, cause energy consumption large, Energy efficiency is low; Again, because cupola well does not have inner lining refractory block, the material transferring heat is very fast to the speed of cupola well cooling water tank, even replenish a large amount of heats, the temperature in the stove also can only reach about ℃, can't process high silicon high calcium material, and is low to the adaptive faculty of raw material; At last, the furnace wall cooling water tank of traditional fuming furnace apparatus and furnace roof cooling water tank are common water tanks, and the vapor pressure of output is low, can't incorporate boiler into, cause heat recovery efficient low, cause energy dissipation. Summary of the invention The purpose of this utility model provides a kind of fuming furnace for the treatment of zinc leaching residue, The utility model achieves the above object by the following technical programs: a kind of fuming furnace for the treatment of zinc leaching residue is comprised of furnace bottom cooling water tank, furnace bottom refractory brick, cupola well cooling water tank, cupola well refractory brick, air intake coal inlet, slag-drip opening, furnace wall cooling water tank, opening for feed, suction opening and furnace roof cooling water tank.The bottom of stove is the furnace bottom cooling water tank, the top outside of furnace bottom cooling water tank is that cupola well cooling water tank, inboard are furnace bottom refractory brick, be provided with air intake coal inlet and slag-drip opening at the cupola well cooling water tank, the furnace wall cooling water tank is above the cupola well cooling water tank, the furnace wall cooling water tank is provided with opening for feed, suction opening is above equipment, the furnace roof cooling water tank is at the top of equipment, the cupola well fireproof brick inner lining is in the space of furnace bottom refractory brick and cupola well cooling water tank formation, and furnace wall cooling water tank and furnace roof cooling water tank are made of the waste heat boiler water wall tube. Described cupola well refractory brick is a kind of in refractory fireclay block, alumina firebrick, aluminium chromium firebrick or the magnesium chromium firebrick, the described lining brick thickness that is lined with cupola well refractory brick in the space of furnace bottom refractory brick and cupola well cooling water tank formation is 200mm～500mm, described water wall tube is boi1er tube, weldless steel tube or alloy steel pipe, the pipe outside diameter is 30mm～60mm, thickness of pipe 3.0mm～6.0mm. Outstanding advantages of the present utility model is: Owing in the space of furnace bottom refractory brick and cupola well cooling water tank formation, be lined with cupola well refractory brick; strengthened the heat insulation effect in molten bath; improved furnace thermal efficiency; also protected the corrosion of slag to water tank; prolonged the life cycle of water tank, simultaneously, owing to furnace wall cooling water tank, furnace roof cooling water tank are made of the waste heat boiler water wall tube; can direct production steam, improved heat recovery efficient. The utility model also has the advantage of heat utilization efficiency height, life cycle length except the fuming volatilization refining slag function that possesses traditional fuming furnace fuming furnace.
