技术领域technical field
本实用新型属于冷却技术领域，尤其涉及一种用于高炉软水闭路循环冷却系统中软水的冷却装置。The utility model belongs to the technical field of cooling, in particular to a cooling device for soft water in a closed-circuit cooling system for soft water of a blast furnace.
背景技术Background technique
目前，在高炉软水闭路循环冷却系统中软水的冷却方式有干式空冷器、板式换热器(水-水冷却)、蒸发式空冷器等几种冷却方式，干式空冷器由于受环境温度的影响较大且在夏季高温季节达不到生产工艺要求的温度，冬季又需有防冻措施，因此已逐渐被淘汰；目前板式换热器(水-水冷却)的方式虽然冷却效果较好，水温控制稳定，但需另建二次水冷却泵站，占用大量的土地面积，且需消耗大量的建设投资及巨大的运行费用；蒸发式空冷器虽然也能达到要求的温度，但在管束外表面极易结垢，清洗非常困难且需耗费大量的清洗费用，严重影响冷却效果，导致最终无法满足生产工艺的要求。At present, there are several cooling methods for soft water in the closed-circuit cooling system of blast furnace soft water, such as dry air cooler, plate heat exchanger (water-water cooling), and evaporative air cooler. The dry air cooler is affected by the ambient temperature. It has a greater impact and cannot reach the temperature required by the production process in the high temperature season in summer, and antifreeze measures are required in winter, so it has been gradually eliminated; although the current plate heat exchanger (water-water cooling) method has a better cooling effect, the water temperature The control is stable, but another secondary water cooling pump station needs to be built, which takes up a large amount of land area, and consumes a large amount of construction investment and huge operating costs; although the evaporative air cooler can also reach the required temperature, but the outer surface of the tube bundle It is very easy to scale, and it is very difficult to clean and it takes a lot of cleaning costs, which seriously affects the cooling effect and ultimately fails to meet the requirements of the production process.
实用新型内容Utility model content
本实用新型的目的在于克服上述现有技术的不足，提供一种既能满足冷却效果又能节省项目建设投资和运行费用的闭式循环水系统的水-水冷却装置。The purpose of this utility model is to overcome the shortcomings of the above-mentioned prior art, and provide a water-water cooling device of a closed circulating water system that can not only meet the cooling effect but also save project construction investment and operating costs.
本实用新型是这样实现的，该闭式循环水系统的水-水冷却装置由冷却塔、板式换热器和循环水泵经管路连接而成，循环水泵和板式换热器位于冷却塔的下方，冷却水进水通过管路由冷却塔经循环水泵加压后进入板式换热器，冷却水出水通过管路由板式换热器返回冷却塔，被冷却水进水通过管路进入板式换热器，被冷却水出水通过管路由板式换热器排出。The utility model is realized in this way. The water-water cooling device of the closed circulating water system is formed by connecting a cooling tower, a plate heat exchanger and a circulating water pump through pipelines. The circulating water pump and the plate heat exchanger are located below the cooling tower. The cooling water enters the plate heat exchanger through the pipeline and is pressurized by the cooling tower through the circulating water pump. The cooling water exits through the pipeline and returns to the cooling tower from the plate heat exchanger. The cooling water outlet is discharged from the plate heat exchanger through the pipeline.
本实用新型闭式循环水系统的水-水冷却装置利用板式换热器进行热交换，使被冷却水(高炉软水闭路循环冷却系统中软水)冷却到工艺要求的温度。冷却水由冷却塔经循环水泵加压后直接送入板式换热器，由板式换热器出来后直接返回冷却塔冷却，再由循环水泵重新加压送入板式换热器进行换热。The water-water cooling device of the closed circulating water system of the utility model utilizes a plate heat exchanger for heat exchange, so that the cooled water (soft water in the closed circuit cooling system of blast furnace soft water) is cooled to the temperature required by the process. The cooling water is pressurized by the circulating water pump from the cooling tower and directly sent to the plate heat exchanger. After coming out of the plate heat exchanger, it is directly returned to the cooling tower for cooling, and then re-pressurized by the circulating water pump and sent to the plate heat exchanger for heat exchange.
本实用新型闭式循环水系统的水-水冷却装置综合了现有冷却装置的优点，将冷却塔、循环水泵与板式换热器优化组合成一体，将循环水泵和板式换热器布置在冷却塔的下部，缩短了装置内的管路长度，从而减少了系统的阻力；充分利用了冷却塔与循环水泵之间的高度差，减少了循环水泵的扬程，从而降低了运行费用。该装置不需另建二次水冷却泵站，从而节省占地面积及项目的投资。本实用新型可设计成单元结构，根据被冷却水量的大小来选择装置的数量。The water-water cooling device of the utility model closed circulating water system combines the advantages of the existing cooling device, optimizes the combination of the cooling tower, the circulating water pump and the plate heat exchanger, and arranges the circulating water pump and the plate heat exchanger in the cooling The lower part of the tower shortens the length of the pipeline in the device, thereby reducing the resistance of the system; making full use of the height difference between the cooling tower and the circulating water pump, reducing the head of the circulating water pump, thereby reducing operating costs. The device does not need to build another secondary water cooling pumping station, thereby saving floor area and project investment. The utility model can be designed as a unit structure, and the number of devices is selected according to the amount of cooled water.
