Description
Technical field
What the utility model related to a kind of waste heat utilizes system again, particularly the waste heat of the attached product high-temperature slag of the pyrometallurgy stove system that carries out recycling.
Background technology
As everyone knows, the pyrometallurgy stove in the process of ore smelting, except that reclaiming valuable metal, a large amount of high-temperature slag of also attached product.Up to the present, high-temperature slag accounts for the 50-85% into the stove weight of material, nearly all smeltery, especially large-scale smeltery adopts the method discharging slag that is interrupted the shrend of deslagging water under high pressure, a large amount of high temperature furnace slag sensible heats can't be utilized, according to heat Balance Calculation, high temperature furnace slag sensible heat accounts for about 50% of heat expenditure, and a large amount of heat is wasted in flushing cinder water and the atmosphere like this in vain.Therefore, how to recycle the high-temperature slag waste heat is the problem of metallurgical expert and pyrometallurgy enterpriser thinking always, also is to require progressively to realize one of measure that subtracts carbon metallurgy instantly, does not still have effective device or equipment at present and realizes this goal.
Summary of the invention
The purpose of this utility model is intended to overcome the defective of prior art, and a kind of system that can fully reclaim the high temperature furnace slag waste heat is provided.
High-temperature slag residual neat recovering system described in the utility model, constitute by ore-smelting electric furnace, the cold slag plug of electroslag saliva, insulation slag chute, high-pressure blast injector, wind-heat interchanger, the broken electroslag slag ladle of wind and warm-air pipe, ore-smelting electric furnace slag notch place is connected with the cold slag plug of electroslag saliva, be connected by being incubated slag chute between electroslag outlet and the wind-heat interchanger, be connected with the high-pressure blast injector in the porch of wind-heat interchanger, the exit of wind-heat interchanger is connected with warm-air pipe, and the broken electroslag slag ladle of wind is positioned at the below of wind-heat exchanger outlet.
Be connected with dust arrester on the warm-air pipe described in the utility model.
For hot blast can be connected, balanced, stablize the user that offers with safety, the utility model is installed a cover at electric furnace slag notch place can regulate and control electric furnace slag flow size freely, connect, evenly, the slag-draining device of safety: the cold slag plug of electroslag saliva, the cold slag plug of electroslag saliva is operated by electrical control mechanism, provide high-pressure blast to the high-pressure blast injector at air compressor, high-pressure blast is ejected into the high temperature furnace slag of the molten condition that the hot stove in ore deposit continuously outflows in the wind-heat interchanger, molten slag is in small, broken bits by high-voltage high-speed wind, be solidified into graininess wind crushed slag, heat exchanger by continuous motion connects discharge, and the hot blast of being heated then is sent to the hot blast user by warm-air pipe.The characteristics of the utility model apoplexy heat exchanger are to increase slag and the sufficient contact area of wind and the sufficiently long time is provided, and impel safer the carrying out of heat exchange of slag and wind, and cold slag is separated with hot blast.And the electric furnace slag is used a spot of micronic dust of generation in the broken process of high-pressure blast wind, is mixed in the high-pressure blast, to ventilation shaft, draught fan impeller can produce wearing and tearing, and is unfavorable to producing, therefore, adopt a drum type brake electric cleaner to purify hot blast, make the hot blast dustiness in suitable scope, realize safety in production.
High-temperature slag residual neat recovering system described in the utility model, large-scale pyrometallurgy stove, as the ore-smelting electric furnace of melting dilval, the slag temperature is up to 1550 ℃, the slag amount accounts for the 85-90% into the stove inventory, and the heat that slag is taken away is more than 50% of whole heat expenditures.Can fully effectively recycle in order to make this part heat.The utility model is intended the high temperature furnace slag of the broken molten condition of high-pressure blast winding-up wind of employing normal temperature state, makes it be solidified into the graininess slag rapidly.Make slag temperature drop to 65 ℃+environment temperature from 1550 ℃, and the high-pressure blast temperature rise to 500 ℃ from normal temperature, has finished heat conversion between high temperature furnace slag and the high-pressure blast.The utility model is simple and reasonable, can effectively the waste heat in the electrothermal furnace smelting process be fully utilized.
