Description
Technical field
The present invention relates to the ferrous metallurgy field, especially refer to a kind of device that is used for steel product cooling and waste heat recovery.
Background technology
Ferrous metallurgy is a mainstay of the national economy industry, and steel billet, coil of strip, steel plate, shaped steel etc. are the main productss of steel industry.Influenced by smelting technology, product forms the back and is in the condition of high temperature toward contact, such as the temperature of coils of hot-rolled steel, shaped steel all about 500-600 ℃, the temperature of steel billet even higher.This pyritous product inconvenience transportation of entrucking in time thereby influence working efficiency simultaneously, can make the ambient temperature rising, influences operator's working conditions, and a large amount of heat energy loses in vain, also can cause the waste of the energy.
Existing one to be called " spray-type condensation waste-heat recovery device " patent No. be the utility model patent of CN201020613361.0; A kind of spray-type condensation waste-heat recovery device is disclosed; Comprise the square casing that has support; Have into mouth and smoke outlet on the housing, lower housing portion links to each other with rising pipe; Be provided with separator in the housing of said smoke outlet below, the separator below is provided with shower, and the shower below is provided with some drip water plates; Said some drip water plates are vertical arrangement, are placed horizontally in the housing, and are connected to a fixed with the inwall of housing.The advantage of this utility model is: realized the convection type heat exchange, and increased the contact area of flue gas and water of condensation greatly through drip water plate, the heat of flue gas can be fully utilized; But this patented technology has only realized efficient waste heat recovery, and the chilled product function does not circulate.
Summary of the invention
Technical problem to be solved by this invention is to above-mentioned present situation, provides a kind of and can cool off cooling and the waste-heat recovery device that steel product can fully reclaim the waste heat of steel again simultaneously fast.
The present invention solves the problems of the technologies described above the technical scheme that is adopted: 1, a steel product air-cooling chamber is set, through roller-way products such as the coil of strip of heat, steel billet, steel plate, shaped steel is sent into indoorly, with freezing air it is cooled off; 2, be provided with and reclaim that Heat Room cools off warm air and with its heat indoor industrial soft water is heated into LP steam with recycling; 3, air-cooling chamber, recovery Heat Room connect into a recycle system through pipeline, fan, vacuum fan, guarantee that cooling and waste heat recovery process continue to carry out.
As improvement; Air-cooling chamber is the skeleton construction that seals relatively, and it is some that the bottom is provided with tuyere, through fan freezing air sprayed into product is cooled off; The air-cooling chamber top is provided with hot-blast outlet, through vacuum fan and pipeline the warm air in the air-cooling chamber is sent into the recovery Heat Room;
As improving again; Reclaim Heat Room and be the insulation skeleton construction; Comprise evaporator room and multistage cooling room, the air of heat flows through from pipeline, as medium the warm air in the pipeline is carried out cooling heat transferring with industrial soft water; Evaporation indoor section soft water becomes LP steam and recycles through vapour outlet; All be filled with industrial soft water in evaporator room, the cooling room, pass through pipe connection between industrial soft water water inlet pipe and the cooling room, between each cooling room and between cooling room and the evaporator room, soft water receives the control of liquid level switch also can put spontaneous current to low spot from height from the moisturizing of industrial soft water water inlet pipe; To guarantee that each indoorly has a suitable water level, becomes freezing air through warm air after reclaiming Heat Room.According to actual needs, cooling room quantity can be elected 2 or 3 as up to 10.
As further improvement, the air that reclaims Heat Room is connected with fan through pipeline.
Compared with prior art; The present invention utilizes air-cooling chamber, reclaim processing units such as Heat Room cools off steel products such as the steel billet of heat, coil of strip, steel plate, shaped steel fast; Simultaneously waste heat is recycled; Improve production efficiency and reduced cost again, had very much practical value, and had the energy-conserving and environment-protective meaning.

Embodiment
Embodiment describes in further detail the present invention below in conjunction with accompanying drawing.
Like Fig. 1, shown in Figure 2, the present invention includes air-cooling chamber 1, vacuum fan 2, reclaimed Heat Room 3, fan 4 has become a round-robin system through pipe connection.Wherein air-cooling chamber 1 bottom is provided with tuyere 5 and roller-way 14, and top is provided with hot-blast outlet 16; Reclaiming Heat Room 3 is made up of evaporator room 13 and a plurality of cooling rooms 15 and top cold wind outlet 11; There is industrial soft water 12 inside; Carry out cooling heat transferring through pipeline 10 and hot air; Be connected through waterpipe 7 between industrial soft water water inlet pipe 6 and the cooling room, between each cooling room 15 and between cooling room and the evaporator room 13, each water outlet place is provided with liquid level switch 8, and evaporator room 13 is provided with vapour outlet 9.
The principle of work of apparatus of the present invention is: the steel product 17 (legend is a coil of strip) of heat gets into air-cooling chamber 1 through roller-way 14, and fan 4 blows to steel product 17 through tuyere 5 with cold air to carry out becoming warm air after the heat exchange, and steel product 17 also obtains cooling, leaves air-cooling chamber 1 along roller-way 14; Vacuum fan 2 is sent into the air of heat through hot-blast outlet 16 and is reclaimed Heat Room 3, and the air of heat through evaporator room 13 and a plurality of cooling rooms 15, is filled with industrial soft water in evaporator room 13 and the cooling room 15 in pipeline 10; Between each chamber and with industrial soft water water inlet pipe 6 between have waterpipe 7 to be connected, each water outlet receives liquid level switch 8 control, when the water level of evaporator room 13 is lower than set(ting)value; Liquid level switch 8 is opened; Water flows into evaporator rooms 13 from cooling room 15, and the like, guarantee that each indoorly all has a suitable water level; And can improve the transformation efficiency of steam behind the water of the heat entering evaporator room; Help the recycling of waste heat, and make that the warm air cooling performance is better, be convenient to recycle once more.The LP steam that industrial soft waters 12 generate in the evaporator room 13 is recycled through vapour outlet 9, and cooled air sends back to air-cooling chamber 1 recycle through cold wind outlet 11 by fan 4.
