Description
The utility model relates to the device of cooling exhaust waste heat recovery of smelter sintering machine heat sinter and sintering flue residue heat generation steam, particularly a kind of sintering machine waste heat recovery steam raising plant.
In the prior art, sintering deposit is after burning till on the sintering machine, enter cooler, that cooler is with is cold, the ring is cold, three kinds of coolings on the machine, cooling means has: air blast cooling and exhausting cooling, the hot ore deposit temperature of this moment has 700-800 ℃, enters behind the cooler under the effect of air blast or air-introduced machine, makes cold air pass hot ore bed hot ore deposit is cooled off.Generally with cold, the cold cooler of ring 3-4 fan housing arranged, the waste gas in heat of cooling ore deposit is by the fan housing emptying.EGT in first and second number fan housing generally has 200-400 ℃, and directly discharging causes the loss of heat energy, therefore can settle steam raising plant on one, No. two bellows.Steam raising plant can be installed in cooling exhaust flue-gas temperature＞200 ℃ behind deduster on the machine on flue collector.Steam raising plant in the past has the waste heat boiler or the steam generator of radiant type, light pipe formula and heat pipe-type.The waste heat boiler equipment of radiant type and normal optical tubular type is huge, and metal consumption is many, invests very greatly, and can not dismantle, and maintenance, maintenance difficulty are to such an extent as to influence the ordinary production of sintering machine.Though heat pipe evaporator adopts heat pipe as its evaporation element, when single heat pipe failure, do not influence the ordinary production of sintering machine, but occur in sintering machine production unusual, if any partially sintering the bad adaptability of ore deposit when " second-time burning " occurring, occur the booster phenomenon easily, influence SINTERING PRODUCTION.And along with the growth of service time, heat pipe exists Problem of Failure, and quantity of steam is descended, and the user can not produce heat pipe voluntarily, is difficult to accomplish on-call maintenance.The volume of heat pipe evaporator is also bigger, and equipment investment is higher.
The purpose of this utility model is the shortcoming that exists at prior art, provides a kind of and uses reliable, easy to maintenance, equipment volume and invest less sintering machine waste heat recovery steam raising plant.
The technical solution of the utility model summary:
A kind of by soft water preheater, steam generator and steam superheater, the sintering machine waste heat recovery steam raising plant that drum is formed, it is characterized in that but the boiling type soft water preheater is coiled or the light pipe coiled that is welded into by various welding method welding spiral fin coils, the fin tube type steam generator is a cluster case type, form by a plurality of evaporation tube groups, the evaporation tube group is welded by the spiral fin coil of various welding method welding, each evaporation tube group and drum independently constitute natural cycle system or forced circulation system, the evaporation tube group connects with flange, and steam superheater is that high-frequency resistance welding (HFRW) spiral fin coil or light pipe are formed; But boiling type soft water preheater, fin tube type steam generator and steam superheater are arranged in preceding two the cooling fan housings of belt-cooling machine, and steam superheater also can be arranged in other high-temperature flue gas bellows.
Characteristics of the present utility model are that the evaporation tube group breaks down, and can realize the maintenance that do not stop production, the productivity ratio height, and good heat-transfer, system is reliable, resistance to wears, and the accumulatingdust ability is strong.
Fig. 1 is a sintering machine waste heat recovery steam raising plant schematic diagram.
Fig. 2 is the single group of a fin evaporation tube group structural representation.
Fig. 3 is a fin coiled pipe structural representation.
Accompanying drawings provides following embodiment:
See Fig. 1, sintering machine waste heat recovery steam raising plant is positioned at 1#, the 2# cooling fan housing of sintering machine salband 7 tops, but is formed by connecting by softened water tank 6, deoxygenation water pump 5 boiling type soft water preheaters 4, fin tube type steam generator 2, steam superheater 3 and drum 1 usefulness pipeline.Above sintering machine salband 7, be provided with 1# and 2# cooling fan housing, but be provided with boiling type soft water preheater 4 in the 2# cooling fan housing, its water inlet is connected by pipeline and softened water tank 6, pipeline is provided with deoxygenation water pump 5, delivery port is communicated with drum 1 with pipeline, drum 1 links to each other with fin tube type steam generator 2 lower collecting box, the fin tube type steam generator is arranged in the 1# cooling fan housing, its upper header is communicated with drum, the top of drum 1 is communicated with steam superheater 3 arrival ends with jet chimney, steam superheater 3 is arranged between steam generator 2 and the sintering machine salband 7, port of export output superheated steam.See Fig. 3, but boiling type soft water preheater 4 is to be welded by coiled pipe 10 or light pipe coiled pipe 10, coiled pipe 10 or light pipe coiled pipe 10 are welded into by high-frequency resistance welding (HFRW) spiral fin coil 9.See Fig. 2, fin tube type steam generator 2 is collection case 11 forms, form by a plurality of evaporation tube groups 8, the evaporation tube group is welded by the high-frequency resistance welding (HFRW) spiral fin coil, each evaporation tube group and drum independently constitute natural cycle system or forced circulation system, each evaporation tube group is to be welded by 1-5 row's finned tube and two ends header, and header is arranged in the box inside or the outside, and the evaporation tube group can keep flat, place vertically or tiltedly put according to field requirement.See Fig. 3, fin tube type steam superheater 3 is welded into coiled pipe for high-frequency resistance welding (HFRW) spiral fin coil 9 or light pipe is formed.But the normal temperature demineralized water is heated to nearly saturation state through boiling type soft water preheater 4, enter 2 heat absorptions of fin tube type steam generator and be vaporizated into saturated vapor, further be heated into superheated steam through steam superheater 3 again, improved the heat energy utilization rate of sintering machine, reduced energy consumption.
The utility model is applied to sintering machine cooling machine waste gas waste heat and sintering machine flue residue heat and reclaims, and wherein the cooler form is cold for being with, ring is cold, cool off on the machine, and cooling means is that air blast cooling and exhausting are cooled off.
