Description
Technical field
The utility model relates to the heat recovery field, relates in particular to a kind of device that the heat that should distribute of hot industry slag is reclaimed.
Background technology
At present, because the requirement in ore deposit increases suddenly, can not satisfy the demand in the ore deposit that fused salt electrolysis process refining ore deposit produces, usually use a kind of mining and metallurgy smelting method that at high temperature oxide ore is reduced into metallic ore at each tame iron-smelter, steel mill in the process of smelting with reducing agent, this method is referred to as reducing process, also claim thermal reduction, thermal reduction refining ore deposit method has Pidgeon process refining ore deposit method, semicontinuous smelting silicothermic process ore deposit method, bohr Zha Nuofa refining ore deposit method, carbothermy refining ore deposit and the hot method refining of carbide ore deposit method etc., and characteristics are as described below separately for it:
1. Pidgeon process refining ore deposit method is raw material with the dolime, and ferrosilicon is a reducing agent, adds fluorite, and material is loaded in the heat-resisting alloy steel reduction jar through grinding briquetting, and metallic ore is produced in reduction under 1473K temperature, 1～10Pa vacuum;
2. semicontinuous smelting silicothermic process ore deposit method adopts continuously and regularly feeds in raw material, periodically ore removal is slagged tap, so be called semicontinuous ferrosilicon process.This method is a raw material with dolomite, bauxite, and ferrosilicon is a reducing agent, goes back the original production metallic ore in the single-phase vacuum electric furnace under 1773～1873K, 3400～4000Pa vacuum;
3. bohr Zha Nuofa refining ore deposit method is improving one's methods of Pidgeon process refining ore deposit, adopts vertical electric internal thermal reducing furnace.Carbothermy refining ore deposit is a raw material with ore deposit, water chestnut ore deposit, and coke or petroleum coke are reducing agent, after briquetting, reduces operating mine in three-phawse arc furnace under 2273～2573K temperature;
4. the hot method refining of carbide ore deposit method is a raw material with ore deposit, water chestnut ore deposit, and calcium carbide is reducing agent, and its production method is similar to Pidgeon process refining ore deposit basically.
Be applicable to relatively that wherein industry refining ore deposit is three kinds of Pidgeon process refining ore deposit method, semicontinuous smelting silicothermic process ore deposit method and bohr Zha Nuofa refining ore deposit methods etc.
And in the process in above-mentioned various reducing process refinings ore deposit, the hot industry slag that must have a large amount of temperature to be about 1200 ℃ is discharged, in order to utilize this part energy, conventional method is as the high temperature chamotte in the manufacture of cement, adopt air-cooled method that heat is cemented out from grog, make cold wind become hot blast, produce steam by waste heat boiler again, be used for generating electricity or heat supply.But this method is difficult to be applied to the heat recovery field of hot industry slag, wear into and suppress balling-up again after powder mixes because slag is various raw materials, most of still spherical under the condition of high temperature after smelting, but along with decrease of temperature, spherical slag fragmentation, become powdery again, be mixed in and add dust arrester in the hot blast and could discharge, very likely will consume more energy and a large amount of investments in order to save this part energy.
Application number 200610200646.X, Chinese patent, a kind of magnesium and the magnesium alloy resource cyclic utilization system of on 06 30th, 2006 applying date.The formation of this system comprises the smeltery that magnesium and magnesium alloy are produced, Mg-slag brick factory, calcium carbonate factory, coal water mixture plant that waste residue, waste water, the waste gas that produces in magnesium and the magnesium alloy production process is utilized again, and waste heat steam boiler, life office heating circulating cooling system; The smeltery comprises the rotary kiln workshop that mainly comprises magnesium and magnesium alloy production process, reduction plant, magnesium refining plant, magnesium alloy smelting shop; This system also carries out purified treatment to finally discharged gas, makes the gas of discharging meet the discharge standard that low temperature hangs down dirt.
