Description
Technical field
The utility model relates to generation technology, particularly relates to waste water residual heat TRT.
Background technology
China's industrial production, the most all produces and discharges the middle hot waste water of a large amount of 70～90 DEG C, especially iron and steel and chemical enterprise, quenches in slag, Blast Furnace Gas Washing technique at blast furnace, and spent hot water's discharge capacity of each blast furnace is about about 2000 ton hour.
The big country of steel production in China, the annual production of iron and steel accounts for the 40% of Gross World Product.Either steel-making or ironmaking, will produce substantial amounts of slag.In Ferrous Metallurgy stove, produce the high temperature furnace slag of 1400～1500 DEG C, after cinder notch flows out, again when slag runner enters flushing cinder chute, with certain water yield, hydraulic pressure and the chute gradient, water is made to become certain angle of cut with slag stream, slag, by cold water shock, bursts into the qualified grain slag of certain particle size.
After pulp water separates, slag is used as construction material；With the washing slag water that high temperature furnace slag carries out heat exchange, enter flushing cinder pond.Flushing cinder pond generally takes up an area thousand of square metres, and above flushing cinder pond, hot vapour soars, and washing slag water temperature is maintained at 60～80 DEG C throughout the year, is a huge potential heat energy energy.
1 ton of pig iron often smelted by steel mill's blast furnace, the heat that slag loses is at 0.81GJ～0.87GJ, account for the 6.61%～7.5% of total amount of heat income, signature coal is that 27.77kg～29.78kg fully burns liberated heat, calculating with slag ratio 0.44, the heat of slag per ton loss is about 63.9kg mark coal and burns completely liberated heat.
Wind Water Quenching Slag technique is used in certain factory's blast-furnace slag process the most at present, and wind is taken from dynamics factory's cold wind for blast furnace, and water comes from water in the industry that special water pump extracts.At slag runner ditch head, hydraulic pressure is all at about 0.22MPa, and the water yield about goes out 8 times of the quantity of slag accordingly.During wind Water Quenching Slag, blast furnace cinder (about 1450～1500 DEG C) is broken up by the kinetic energy of geomantic omen mixture, and the blast furnace cinder after breaing up is sufficiently mixed with water, and pulp water carries out heat exchange, and slag temperature drop to about 65～90 DEG C, water temperature is increased to same equitemperature.
Rough estimation, 1 ton of blast furnace cinder of often quenching at present about needs 8 tons of water, washing slag water turns again to middle pond and only remains about 7.15 tons, 1 ton of blast furnace cinder of the most often quenching loses water in 0.85 ton, wherein become steam for about 0.65 ton, by grain slag adsorb for about 0.2 ton, i.e. blast furnace often produces the 1t pig iron, take around consumption flushing cinder in water 0.36t.The most i.e. waste water resource, lost again the exhaust heat of slag flushing water of preciousness.
Three 2500m of certain factory3Blast furnace and 1 1260m3The pig iron about 7,500,000 tons produced per year by blast furnace, produces 3,300,000 tons of blast furnace slags simultaneously, and the heat of annual blast furnace slag loss is approximately equivalent to 210,000 tons of mark coals and burns completely liberated heat.
Exhaust heat of slag flushing water reclaims and is used for heating or heat soft water water source, introduces the 10% of recyclable blast furnace slag total amount of heat according to related data, and recovery time is March annual November to next year, i.e. recovery time to be about 150 days.
Utilizing exhaust heat of slag flushing water, waste heat recovery to be mainly used in heat supply in winter, useless in waste heat recovery in summer, whole waste heat recoveries can only be cut off.
Blast furnace slag washing slag water heat is a preferred plan for generating, can make full use of blast furnace slag heat throughout the year, but also not have successful precedent both at home and abroad so far.
In 1980, before i.e. 35 years, Beijing Municipal Government preside over, the Chinese Academy of Sciences, Harbin Institute of Technology, Guangzhou energy institute and Beijing boiler factory composition " Shoudu Iron and Steel Co slag bath cogeneration seminar ", once carried out blast furnace slag washing slag water heat and designed for scientific research activity and the detailed protocol of generating, but ended without result.
