Raw 2.5 hundred million tons of high-temperature liquid state slag.The correlative study of many years has been carried out both at home and abroad, it is desirable to blast furnace cinder heat is made full use of,
Realize heat recovery.
Chinese patent CN106282445B, 2017 publication date January 4 disclose a kind of " recycling blast furnace slag waste heat
Device and recovery method ", this method are mixed with high-temperature liquid state slag using metal ball, obtain 500 DEG C~800 DEG C blast furnace slag and
The solid mixt of metal ball, mixture complete the recycling of broken apart and waste heat by rotating metallic cage, and this method obtains molten
Slag fragment is difficult to realize to be recycled, and the solid mixt of 500 DEG C~800 DEG C of blast furnace slag and metal ball is in rotating metallic cage
Complete broken apart, very serious to the abrasion meeting of metal cage under the condition of high temperature, the operation to equipment life and whole system
Rate can be generated and be seriously affected.
Precipitating filtration method (often claiming bottom filter method) grain slag technique is generallyd use both at home and abroad to handle slag.State of Blast Furnace is advanced
Row hydraulic discharged slag after being smashed slag with water quenching, becomes loose slag-water slurry (often claiming grain slag), grain slag enters through sluice
Filtering ponds, liquid water are filtered through the filtering layer in filtering ponds, are left solid wet slag particle in filtering bottom of pond portion, are then passed through bridge
Formula grab bucket crane grabs slag particle, entrucking is transported outward.Slag particle (partial size 0.2mm~3mm) purposes obtained after water quenching is wide
It is general, it can be used as cement materials, thermal insulating filling etc., clinker made to be fully used.
(about 70 DEG C~90 DEG C) of blast furnace slag quenching water are used as a kind of temperature waste heat sources, have the characteristics that temperature is stable, flow is big,
For the UTILIZATION OF VESIDUAL HEAT IN of washing slag water, Chinese patent CN207585372U discloses " blast furnace punching July 6 2018 publication date
Washing slag water is led to circulatory pool by elevator pump, drainage tube by pulp water afterheat utilizing system ", the system, and circulatory pool connects heating pump,
The water outlet of heating pump connects sintered mix water pipeline by water supplying pipe, and it is dense that circulatory pool also connects dynamics factory by first pipe
Brine discharge tube line, can also be by heat exchanger after, after the waste heat of superfluous water is made full use of inject circulatory pool follow
Ring uses.Washing slag water is led to circulatory pool from pond and other measures is taken to carry out UTILIZATION OF VESIDUAL HEAT IN again by the system, can be lost so big
Calorimetric amount is unfavorable for the thermal energy recycling of washing slag water.
Patent CN207121610U, March 20 2018 publication date disclose " blast furnace slag flushing vapor waste heat recycling
Utilize system ", which will be delivered to steam accumulation of heat through steam reheater after the collection of flushing cinder water vapour using extractor fan
Device, lithium bromide refrigerating water dispenser group, are finally condensed into condensed water for steam and generate chilled water.The system is needed in original grain slag system
Additional mating large number of equipment on the basis of system, such as extractor fan, steam reheater, steam accumulator, gas-liquid heat exchanger
Deng system flow complexity, equipment investment height；Not only there are a large amount of washing slag waters (about into washing slag water circulating water pool in the system
70 DEG C~90 DEG C), there are also the slag particle obtained after slag water quenching, other part steam (about 60 DEG C~100 DEG C) cannot be by draught hood
Trapping can enter circulating water pool along pipeline, and the washing slag water of circulating water pool and the heat of steam are not recycled adequately.
Patent CN101265039B 2008 publication dates September 17th, discloses a kind of " environment-friendly type bottom filter process State of Blast Furnace
Slag treatment equipment and processing method ", this method can reduce flushing cinder water, reduce water consume, improve the rate of filtration, reduce filtering ponds
Occupied area, the technology have been applied for many years and have achieved good result.The water quenching of high-temperature liquid state slag is by recirculated water (about 40
DEG C) complete, it needs to use after cooling down washing slag water (about 70 DEG C~90 DEG C), in the method, washing slag water is through filtering
Cooling tower is directly got to by upper tower pump after pipe to be cooled down, and not only wastes the thermal energy of washing slag water, and increase cooling tower
Workload.
By being analyzed above it is found that although the recoverable side of blast furnace grain slag system filtering ponds heat has been provided in the prior art
Method, but there have various defects to have in different degrees of and different aspect to be to be solved, it is necessary to study new blast furnace grain slag system mistake
Filter tank heat energy recovering method realizes that the Efficient Cycle of the energy utilizes and reduces air pollution.
In the treatment process of blast furnace cinder, a large amount of high-temperature steams of existing granulation also have filtering ponds temperature stabilization, stream
Big washing slag water is measured, there are also steam existing for filtering ponds surface long term when flushing cinder, recycles the thermal energy of these washing slag waters and steam simultaneously
The putting idle discharge of sulfur-bearing steam is reduced to be of great significance for energy-saving and emission-reduction.
