Background technology

During modern sintering process, " cooling " is one of more crucial operation.Sintering deposit is after the roasting of sintering machine; form high temperature finished product ore deposit; how on the premise of not affecting its quality and yield rate, it can be carried out protectiveness cooling; finished product ore storage bin can be sent into through belt feeder; its entrained sensible heat energy perfection is recycled simultaneously, be the problem that skilled worker constantly studies in the industry all the time.Since the sixties in 20th century, the cooling technique of sintering deposit is developed rapidly, and it is broadly divided into belt cooling, ring type cooling cools down three major types with disc type.In the market competition in later stage, belt cooling technology is eliminated, and the cooling of remaining ring type is all respectively arranged with its pluses and minuses with disc type cooling technology.But Integrated comparative, the cold utilization rate of waste heat colder than ring of dish is more preferable (all sintering mine sensible heats are all recycled utilization), therefore dish cold market abroad is applied widely, and this patent is also illustrated around dish cold technology.

Dish cold technology starts development from the seventies, starts as transverse type dish most cold, i.e. cooling wind is to move to outside circulation from the internal ring of dish cold, is horizontally through the bed of material to be cooled and its heat exchange, and the cooling wind after heat exchange is complete is directly outer drains into air.Do so is the most uneconomical the most not environmentally, through for many years constantly study optimization, up-to-date dish cold technology is Mitsubishi Hitachi and middle Sheng iron and steel proposes " air-draft-type longitudinal direction dish refrigeration technique ".This technology uses convulsion, and by cooling wind bottom air suction material to be cooled, the most up longitudinally through the bed of material, finally from bed of material top, blowout enters subsequent handling.The program, compared with the scheme started most, has had the biggest optimization and progress, has described in detail below for the program.

JP2008232519A (Rhizoma Sparganii Hitachi and middle Sheng iron and steel, call D1 in the following text) disclose air-draft-type longitudinal direction dish refrigeration technique, see Fig. 1 therein: heat sinter and enter feed chute from sintering machine tail clan, the stock column of certain altitude it is piled in chute, so on the one hand, it is the effect playing uniform blanking, is on the other hand to play material envelope to prevent charging aperture string wind action.Mineral aggregate continues down through in entrance dish cold casing after hood, pushes into the stock column of certain altitude.Meanwhile, affected by the negative pressure of air exhauster, air near dish cold can be inhaled in stock column via BAIYE air-intake device, from the bottom up through stock column heat exchange therewith, air after heat exchange passes entrance air outlet from stock column end face, it is sent to gravitational precipitator and waste heat boiler, eventually passes after air exhauster by outer row.Sintering feed after being cooled down by air forms the annular accumulation area that cross section is 37 degree of stocking angle trianglees at dish cold lower tray, and when being turned to discharge zone, sintering feed is scraped by scraper plate device, completes refrigerating work procedure and enters next process links.

" the air-draft-type longitudinal direction dish refrigeration technique " of Rhizoma Sparganii Hitachi and middle Sheng iron and steel is although more conventional technology has marked improvement, but still there are following five point defects:

1) device whole height requires too high: owing to " air-draft-type longitudinal direction dish refrigeration technique " takes convulsion mode, so material envelope must be arranged at gating location, the stock column namely piled up in feed chute in Fig. 1 of D1, material envelope height is with in dish cold casing 1.2～1.5 times of stock column height as standard.The most virtually increase the height of whole series of discs device for cooling, when construction and installation or be accomplished by rising whole sintering machine absolute altitude, or be accomplished by down digging the civil engineering plane of dish cold.No matter select which kind of mode, all can cause a high cost of investment, economic indicator is not calculated；

2) distinguished and admirable open circuit circulation causes utilization rate of waste heat low and pollutes environment: distinguished and admirable for open circuit circulation due to " air-draft-type longitudinal direction dish refrigeration technique ", from waste heat boiler, the row of air out does not recycle, so cause the also air sensible of degree more than 100 to be wasted, outside and, the air of row is contained within a large amount of little granule dust, causes a certain degree of Particulate Pollution for air；

3) material serious wear at charging aperture: owing to " air-draft-type longitudinal direction dish refrigeration technique " arranges material envelope at feed chute, therefore have one section of frictional distance between charge level upper strata in expecting envelope bottom and dish cold casing.Now sintering feed is at high temperature with under the double-deck bad working environments of top stock column extruding, is easy to efflorescence and becomes broken, thus reduce the yield rate of sintering machine when being rubbed；

4) environmental pollution is more serious: the negative pressure convulsion technology taked due to " air-draft-type longitudinal direction dish refrigeration technique ", so it is not provided with seal closure device at lower box pallet.So when sintering deposit is scraped by doctor blade device, easily cause a large amount of fine particle and splash with dust.And once air exhauster breaks down maintenance, the material dust pushed around dish cold all can enter air, causes the operating environment that machine is other and ill effect；

5) the waste heat boiler thermal efficiency is not up to the highest: due to " air-draft-type longitudinal direction dish refrigeration technique " not passing the air of the bed of material according to the accurate classification of pathogenic wind-warm, but all it is mixed into waste heat boiler, so when low-temperature zone outlet pathogenic wind-warm is too low, the air themperature entering waste heat boiler will certainly be dragged down, thus reduce the thermal efficiency value of waste heat boiler.

For above-mentioned five strip defects, the Technology of " air-draft-type longitudinal direction dish refrigeration technique " is conducted in-depth analysis by we with device technique, by repeatedly groping and improving and optimizating, have developed a set of can not increase the patent formula technology that cooler height, distinguished and admirable closed cycle, sintering deposit yield rate be high, the other environmental pollution of machine is significantly alleviated, make every effort to effectively solve the problem that prior art exists, contribute for sintering circuit energy-conserving and environment-protective index.
