Description
Technical field
The utility model relates to a kind of equipment and the using method that reclaim blast furnace slag heat, belongs to blast furnace slag treatment facility and method and technology field.
Background technology
Blast furnace slag is the byproduct of blast furnace ironmaking, and often produce 1 ton of pig iron and about produce 300 ~ 400 one kilo of slag, outflow temperature is at 1450 ~ 1650 DEG C.1 ton of blast furnace slag, about containing the heat of 1700MJ, amounts to 64 kilograms of standard coals.In recent years the blase furnace cast iron output of China is more than 500,000,000 tons, and the generation of blast furnace slag is up to 1.6 hundred million tons, and institute's heat content amounts to 1036.8 ten thousand tons of standard coals.At present, process blast furnace slag generally adopts water quenching, and the method does not only reclaim the waste heat of blast furnace slag, and consumes a large amount of new water, H
2s and SO
xenter air Deng obnoxious flavour with steam, promote the formation of acid rain, the accumulation of Water Quenching Slag occupies a large amount of land area, even there will be sand, is degrading Working environment, causes serious environmental pollution.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of blast furnace slag heat reclaim unit; this retrieving arrangement can when not consumption of new water; utilize blast furnace slag and heat-transfer medium directly or indirectly to contact and carry out blast furnace slag granulation and waste heat recovery; do not have obnoxious flavour to discharge, be conducive to energy-conserving and environment-protective.
The technical scheme solved the problems of the technologies described above is:
A kind of blast furnace slag heat reclaim unit, it comprises slag ladle, slag trapping box, cooling roller, ring cooling pallet, gas blower, bellows, spout device is arranged at the bottom of slag ladle, spout device is suitable for reading relative with slag trapping box, organizes cooling roller in slag trapping box more, and often organizing cooling roller has two cooling roller horizontal parallel arrangements, many groups cooling roller is parallel installation from top to bottom, the bottom opening of slag trapping box is relative with ring cooling pallet, and ring cooling pallet lower segment arranges cooling blower, and the top of ring cooling pallet is provided with bellows.
Above-mentioned blast furnace slag heat reclaim unit, described cooling roller is made up of roller shell, roller core, and roller shell is sleeved on roller core periphery, and be roller gap between roller core and roller shell, roller gap is connected with cooling water pipeline.
Above-mentioned blast furnace slag heat reclaim unit, described cooling roller is connected with drive unit, and two cooling rollers often organized are simultaneously respectively to outer sideway swivel, and cooling roller is provided with roll gap spacing adjusting device.
The beneficial effects of the utility model are:
After blast furnace slag enters slag trapping box, slag scrolls up by cooling roller, makes slag have longer setting time, carries out water-cooled in cooling roller, makes slag continuous solidification become the slag sheet of thickness about 3 ~ 10mm.Slag sheet after solidifying cracks, breaks into pieces in dropping process.Fall into after on ring cooling pallet and cool, cooled slag sheet can go to carry out fragmentation as required and utilize.Ring cooling pallet lower segment arranges cooling blower, feeds cold wind from pallet bottom, and cold wind is heated through after about 0.5 meter of thick fresh slag layer, and the heat smoke of generation collects at top bellows, is then drawn by induced draught system, supply waste heat boiler producing steam.
The utility model can reclaim blast furnace slag heat in high-quality ground, blast furnace ironmaking process energy consumption is declined to a great extent, simultaneously saving water resource, and does not cause environmental pollution, can substitute existing water quenching process blast furnace slag, have significant economic benefit and social benefit.
Accompanying drawing explanation
Fig. 1 is blast furnace slag heat reclaim unit structural representation of the present utility model.
In figure, mark is as follows: slag runner 1, slag ladle 2, spout device 3, first group of cooling roller 4, second group of cooling roller 5, the 3rd group of cooling roller 6, slag trapping box 7, ring cooling pallet 8.
Embodiment
Blast furnace slag heat reclaim unit of the present utility model comprises slag ladle 2, slag trapping box 7, cooling roller, ring cooling pallet 8, gas blower, bellows.
Show in figure, spout device 3 is arranged at the bottom of slag ladle 2, and spout device 3 is suitable for reading relative with slag trapping box 7.Liquid high-temperature slag in slag ladle 2 is flowed in slag trapping box 7 by the spout device 3 bottom slag ladle 2.
Show in figure, in slag trapping box 7, have three groups of cooling rollers, first group of cooling roller, 4, second group of cooling roller 5, the 3rd group of cooling roller 6.Often organize cooling roller and have two cooling roller horizontal parallel arrangements, the parallel installation from top to bottom of many group cooling rollers.Cooling roller is made up of roller shell, roller core, and roller shell is sleeved on roller core periphery, and be roller gap between roller core and roller shell, roller gap is connected with cooling water pipeline.Cooling roller is connected with drive unit, and two cooling rollers often organized are simultaneously respectively to outer sideway swivel, and cooling roller is provided with roll gap spacing adjusting device, and roll gap spacing is fine-tuning.
