Description
Technical field
The present invention relates to refrigerating plant is and in particular to blast furnace slag quenching water heat refrigeration apparatus.
Background technology
In recent years China's commercial production, all produces and discharges a large amount of 70～90 DEG C of high temperature waste water every year, especially iron and steel and
Chemical enterprise, blast furnace quench slag, in Blast Furnace Gas Washing technique, spent hot water's discharge capacity of each blast furnace about 2000 tons/little
When about.
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,
Substantial amounts of slag will be produced.In Ferrous Metallurgy stove, produce 1400～1500 DEG C of high temperature furnace slag, after flowing out through cinder notch, then warp
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, slag with slag stream
By cold water shock, burst into the qualified grain slag of certain particle size.
After pulp water separates, slag is used as construction material；Carry out the washing slag water of heat exchange with high temperature furnace slag, enter washing slag water
Pond.Flushing cinder pond generally takes up an area thousand of square metres, and above flushing cinder pond, hot vapour is soared, and flushing cinder coolant-temperature gage is maintained at 60～80 throughout the year
DEG C, it is a huge potential heat energy energy.
1 ton of pig iron often smelted by steel mill's blast furnace, and the heat that slag loses, in 0.81GJ～0.87GJ, accounts for total amount of heat income
6.61%～7.5%, signature coal fully burns liberated heat for 27.77kg～29.78kg, is calculated with slag ratio 0.44, per ton
The heat of slag loss is about 63.9kg mark coal and burns completely liberated heat.
Certain factory's blast-furnace slag processes upper current wind Water Quenching Slag technique, and wind is taken from the cold wind that dynamics factory supplies blast furnace, and water comes
From water in the industry that special water pump extracts.At slag runner ditch head, all in 0.22MPa, the water yield is about corresponding amount of slag to hydraulic pressure
8 times.During wind Water Quenching Slag, blast furnace cinder is broken up for about 1450～1500 DEG C by the kinetic energy of edema due to wind pathogen mixture, and the blast furnace after breaing up melts
Slag is sufficiently mixed with water, and pulp water carries out heat exchange, and to about 65～90 DEG C, water temperature is increased to same equitemperature to slag temperature drop.
Rough estimation, 1 ton of blast furnace cinder of often quenching at present about needs 8 tons of water, and washing slag water turns again to middle pond and only remains 7.15 tons
Left and right that is to say, that 1 ton of blast furnace cinder of often quenching loses water in 0.85 ton, wherein become steam for 0.65 ton about, by water
Slag absorption for 0.2 ton about, that is, blast furnace often produces the 1t pig iron, take around consumption flushing cinder in water 0.36t.So waste
Water resource, lost the exhaust heat of slag flushing water of preciousness again.
Three 2500m of certain factory3Blast furnace and 1 1260m3About 7,500,000 tons of the pig iron produced per year by blast furnace, produces 3,300,000 tons of blast furnaces simultaneously
Slag, 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 for heating or heating soft water water source, introduces recyclable blast furnace slag total amount of heat according to related data
10%, recovery time be March annual November to next year, that is, recovery time be about 150 days.
Using exhaust heat of slag flushing water, waste heat recovery is mainly used in heat supply in winter, useless in summer waste heat recovery, all remaining
Heat can only be thrown away.
Additionally, the industry such as chemical industry, papermaking, building materials, cement, weaving, pharmacy also discharge a large amount of high temperature waste water, at present this
The waste heat major part of a little waste water is not also obtained by.
