Description
技术领域 technical field
本实用新型涉及一种冷却装置，具体涉及一种软水密闭循环冷却装置。 The utility model relates to a cooling device, in particular to a soft water closed circulation cooling device.
背景技术 Background technique
化工生产装置所用冷却器大多利用循环水冷却，由于循环水池都是开放式，循环水质量很难控制，多淤泥和杂物，易造成列管脏堵，并且循环水硬度较高，在冷却器的细管内流速慢，温度高，容易在细管内产生水垢，影响换热质量。 Most of the coolers used in chemical production equipment are cooled by circulating water. Since the circulating pools are all open, the quality of circulating water is difficult to control. There are many sludges and sundries, which can easily cause dirty tubes and blockage, and the hardness of circulating water is high. The flow rate in the thin tube is slow and the temperature is high, which is easy to generate scale in the thin tube, which affects the heat transfer quality.
设备结垢、脏堵严重后，只能对设备进行清洗或酸洗，这样就无法保证装置的稳定运行，而且清洗过程时间较长，还要将受槽内的物料倒空置换，造成严重的物料浪费，并且高压清洗车清洗费用非常昂贵。多次酸洗，会对设备产生一定腐蚀，严重时出现漏点，给装置的稳定运行带来极大地安全隐患。 After the equipment is seriously fouled and blocked, the equipment can only be cleaned or pickled, so that the stable operation of the device cannot be guaranteed, and the cleaning process takes a long time, and the materials in the receiving tank must be emptied and replaced, causing serious damage. Material is wasted, and high pressure washer cleaning is very expensive. Repeated pickling will cause certain corrosion to the equipment, and in severe cases, leaks will occur, which will bring great safety hazards to the stable operation of the device.
辛醇装置丁醛蒸发器受槽冷却器，管壳程温差较大，列管的循环水侧管壁易结垢。冷却器列管较细，循环水量较小时淤泥易沉积，堵塞列管。 The butyraldehyde evaporator of the octanol unit is cooled by the tank, and the temperature difference between the shell and the tube is relatively large, and the wall of the circulating water side of the tubes is easy to scale. The tubes of the cooler are thinner, and when the circulating water volume is small, the sludge is easy to deposit and block the tubes.
软水由于硬度较低，水质好，基本不会发生结垢和脏堵的情况，所以对设备的腐蚀性较小，设备破损机率小，增加设备使用寿命，保证装置平稳运行。 Due to its low hardness and good water quality, soft water basically does not cause scaling and dirty clogging, so it is less corrosive to equipment, and the probability of equipment damage is small, which increases the service life of equipment and ensures the smooth operation of the device.
