[specific embodiment]
Embodiment one, and shown in Fig. 1, present embodiment provides a kind of tobacco roasting to concentrate heating system, comprises being used for concentrating the boiler 1 that hot water is provided, at the boiler 1 other attemperater 2 that is communicated with boiler 1 by pipeline that is provided with; Pipeline output at attemperater 2 is connected with the pipeline force (forcing) pump 3 that the hot water in the pipeline is pressurizeed, and is connected and installed according to national standard; Be connected with the water flow control valve 4 of hot water current size in the control piper at the pipeline output of pipeline force (forcing) pump 3, pipeline output at water flow control valve 4 is connected with wind-water heat exchanger 5, carry out exchange heat by the air in 5 pairs of barns of wind-water heat exchanger and toast tobacco, described water flow control valve 4 and 5 series connection of wind-water heat exchanger are provided with in groups, between the water return pipeline receiving terminal of the pipeline output of pipeline force (forcing) pump 3 and boiler 1, three groups of water flow control valves (4 have been arranged in parallel, 4 '; 4 ") and wind-water heat exchanger (5,5 '; 5 "), and respectively by water flow control valve (4,4 '; 4 ") the corresponding wind-water heat exchanger (5 of control, 5 '; 5 "), carry out exchange heat according to predetermined requirement and the air in the tobacco roasting barn; Described boiler 1, attemperater 2, pipeline force (forcing) pump 3, water flow control valve (4,4 ', 4 ") and wind-water heat exchanger (5,5 ', 5 ") connect to form closed pipeline heating circuit after series connection back and three groups are arranged in parallel in groups successively in turn.Wherein, and described wind-water heat exchanger (5,5 ', 5 ") adopt finned heat exchanger, use finned heat exchanger, can effectively enlarge heat transfer area, can obtain the secondary heat-transfer area, make heat exchanger structure compacter; Can also improve heat transfer efficiency,, improve heat transfer efficiency because the special construction of fin makes fluid form strong disturbance in passage, thereby reduced thermal resistance effectively.
Embodiment two, shown in Fig. 2, present embodiment and embodiment one unique difference are, between the pipeline output of described wind-water heat exchanger (5,5 ', 5 ") and the water return pipeline receiving terminal of boiler 1, also be provided with and send the pipe circle pump 6 of boiler 1 back to carrying out backwater after the exchange heat in described wind-water heat exchanger (5,5 ', 5 ").
In conjunction with the embodiments two, the concrete course of work of the present invention is done to describe in detail:
During work, it at first is heat supplying process, after normal-temperature water is concentrated heating by boiler 1, from 20 ° of temperature rises to 90 °, be stored into then in the attemperater 2, when the tobacco flue-curing barn needs, hot water adds each the wind-water heat exchanger (5 that is sent to end through pipeline, 5 '; 5 ") in, utilize wind-water heat exchanger (5,5 '; 5 ") a plurality of barns or many production lines are carried out exchange heat, and according to the temperature rise requirement of needs in the barn, regulate water flow control valve (4,4 '; 4 "), control wind-water heat exchanger (5,5 '; 5 ") in the size of the water yield, thereby reach the requirement of regulating temperature in the barn; Then, it is the baking control procedure of tobacco leaf, by the temperature in the temperature sensor detection barn, desired indicator temperature according to each stage needs in the tobacco flue-curing process, respectively the water yield in everywhere wind-water heat exchanger (5,5 ', 5 ") in the barn is regulated by water flow control valve (4,4 ', 4 "), thereby temperature in the control barn everywhere makes the interior air heat of barn even on the one hand, reaches the temperature in each stage in the accurate control tobacco flue-curing process on the other hand; At last, it is the backwater process after the heat exchange, hot water is after wind-water heat exchanger (5,5 ', 5 ") heat exchange; temperature descends, and in order to save the energy, reaches the resources circulation recycling; the backwater after the heat exchange is directly sent back in the boiler 1 by pipe circle pump 6; heat again, still is stored in the attemperater 2 then, proceeds heat supply.
The heat supply that above-mentioned central heating adopts boiler 1 and attemperater 2 to form, in the whole tobacco flue-curing process, resource can be recycling, and the one, reduced the waste of the energy, saved fuel, reduced the pollution of waste gas such as CO2, SO2; The 2nd, central heating only needs personnel to keep an eye in that boiler 1 is other, needs no longer that each barn all is equipped with personnel as in the past, has reduced personnel's labour intensity; The 3rd, according to the desired indicator temperature of each stage needs in the tobacco flue-curing process, respectively the water yield in everywhere wind-water heat exchanger (5,5 ', 5 ") in the barn is regulated by water flow control valve (4,4 ', 4 "), thereby temperature in the control barn everywhere, make the interior air heat of barn even, reach the temperature in each stage in the accurate control tobacco flue-curing process, guarantee the crudy of tobacco leaf.
Tobacco roasting of the present utility model concentrates heating system that other distortion can also be arranged, and can be all types of in the market boilers, heat pump etc. as the boiler in the heating water supply installation; In a word, do conspicuous change, and other every change that does not break away from patent essence of the present invention all should be included within the described scope of claim according to the prompting of above-mentioned example.
