【摘要】 在酒精的生产过程中,通常采用以开放式冷却塔为降温设备的循环冷却水系统,但其降温效果与气候条件密切相关,高温高湿天气时只能通过大量补充新水来保证冷却水的温度,从而造成水资源的浪费。针对该问题,某酒精厂的冷却水系统在原有冷却塔后增加大型离心式制冷机组,实现冷却水温度的有效降低和控制,在改善工艺条件、节约用水和节约运行费用等方面收到了明显的效果,证明制冷降温技术在工业冷却水领域应用的可行性、合理性和必要性。更多还原

【Abstract】 A recirculated cooling water system with open-type cooling-tower is commonly used in alcohol distilleries. However, the cooling effects of such system is closely related to climate, and large quantity of fresh water is supplied to ensure the temperature of cooling-water at high temperature and/or high moisture conditions, which results in the waste of water resources. To settle the problem, 4 large-scale centrifugal-type refrigerators are equipped behind the original cooling tower to achieve effective control of the cooling-water temperature, which has achieved satisfactory effects in technical improvement, water-saving and operation costs saving. Such technical improvement is feasible, rational and necessary.更多还原
