结合图1至图3对本发明提供的低温热***的智能优化控制装备进行说明。图1为本发明的一个实施例的低温热***的示意图。图2为本发明的一个实施例的智能优化控制装备的示意图。图3为本发明的一个实施例的包含智能优化控制装备的低温热***热量智能调控中心的示意图。The intelligent optimization control equipment for the low temperature thermal system provided by the present invention will be described with reference to FIGS. 1 to 3 . FIG. 1 is a schematic diagram of a low temperature thermal system according to an embodiment of the present invention. FIG. 2 is a schematic diagram of an intelligent optimization control device according to an embodiment of the present invention. 3 is a schematic diagram of a low temperature thermal system heat intelligent control center including intelligent optimization control equipment according to an embodiment of the present invention.
所述低温热***10包括热源单元11、热阱单元12以及热量智能调控中心13。所述热量智能调控中心13用于所述热源单元11与所述热阱单元12之间的热量传 递和热量平衡。The low temperature thermal system 10 includes a heat source unit 11 , a heat sink unit 12 and an intelligent heat regulation center 13 . The heat intelligent regulation center 13 is used for heat transfer and heat balance between the heat source unit 11 and the heat sink unit 12.
如图1示出的低温热***10的一个具体实施例中,低温热***10回收物料1、2、3的热量,分别送至各处,为物料4、5、6提供低温热量。在现有的实现中,物料1、2、3原来的温度100-135℃各不一样,但都是通过空冷器或者水冷器冷却到较低温度(一般为50℃以下)后进入下游,物料1、2、3的热量通过空冷和水冷(消耗电能)损失到大气中。物料4、5、6原来的温度70-110℃各不一样,都是通过蒸汽加热到需要的温度,蒸汽可以是外部购买或者通过燃烧煤、天然气等自行生产。由此,现有的实现中,物料1、2、3损失的热量,以及物料4、5、6所需的热量互不关联,从而导致热量的浪费。In a specific embodiment of the low temperature heat system 10 shown in FIG. 1 , the low temperature heat system 10 recovers the heat of the materials 1 , 2 , and 3 and sends them to various places to provide the materials 4 , 5 , and 6 with low temperature heat. In the existing implementation, the original temperatures of materials 1, 2, and 3 are different from 100 to 135 °C, but they are all cooled to a lower temperature (generally below 50 °C) by an air cooler or water cooler and then enter the downstream. The heat of 1, 2, and 3 is lost to the atmosphere through air cooling and water cooling (consumption of electrical energy). The original temperature of materials 4, 5, and 6 varies from 70 to 110 °C. They are all heated to the required temperature by steam. The steam can be purchased externally or produced by burning coal, natural gas, etc. Therefore, in the existing implementation, the heat lost by the materials 1, 2, and 3 and the heat required by the materials 4, 5, and 6 are not related to each other, resulting in waste of heat.
为此,图1中的低温热***10可以建立热水循环。热媒水在热量智能调控中心13通过泵加压后送到热源单元11的物料1、2、3处进行换热升温,升温后返回热量智能调控中心13,经过水量调控送到热阱单元12的物料4、5、6处替代原4、5、6处的蒸汽进行加热。热媒水温度降低后再返回热量智能调控中心13,由热量智能调控中心13的空冷器或者水冷器调节水温后再通过泵加压,通过水量调控送去物料1、2、3处取热完成循环。通过低温热***10的运用,物料1、2、3减少了空冷器或者水冷器的冷却消耗,物料4、5、6减少了加热蒸汽的消耗,达到了热量的利用。To this end, the low temperature thermal system 10 in FIG. 1 may establish a hot water cycle. The heat medium water is pressurized by the pump in the heat intelligent control center 13 and sent to the materials 1, 2 and 3 of the heat source unit 11 for heat exchange and temperature rise, and then returned to the heat intelligent control center 13 after heating, and sent to the heat sink unit 12 after the water volume control. The raw materials 4, 5, and 6 replace the steam at the original 4, 5, and 6 for heating. After the temperature of the heat medium water is lowered, it returns to the heat intelligent control center 13. The water temperature is adjusted by the air cooler or water cooler of the heat intelligent control center 13, and then pressurized by the pump, and sent to the materials 1, 2, and 3 to obtain heat through the water volume control. cycle. Through the use of the low temperature heating system 10, the materials 1, 2, and 3 reduce the cooling consumption of the air cooler or the water cooler, and the materials 4, 5, and 6 reduce the consumption of heating steam and achieve the utilization of heat.
