【摘要】 在酒精及相关产品的生产过程中,为了保证产品的产量、质量和收得率,必须以温度适宜、数量充足的冷却水进行冷却。通常采用的冷却塔等开放式降温设施,在高温高湿大气条件下很难满足需要,只好加大低温新水补充量,从而造成水资源的浪费。为改善酒精生产的冷却条件、减少水资源浪费,针对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,收到了明显的改善工艺条件、节约用水和节约运行费用的效果,也证明了制冷降温技术在工业冷却水领域应用的可行性和合理性。更多还原

【Abstract】 In the production process of ethyl alcohol and its correlates, to guarantee the product’s output, quality and receiving rate, the sufficient cooling-water with appropriate temperature is necessary. Because cooling tower and other open-type cooling facilities commonly used are not always successful to guarantee the temperature of recirculated cooling-water, especially at high temperature and humidity atmospheric condition, more fresh water with lower temperature has to be added in cooling-water to maintain the temperature, so that there is more waste of water. In order to improve the production condition, to decrease the waste of water resource, 4 large-scale centrifugal-type refrigerator are used after the original cooling tower in an ethyl alcohol plant to lower and control the temperature of cooling-water. It’s proven, there are evident effect to improve process condition, to save water and running cost. And it’s also proven, the refrigeration technology for industrial cooling-water’s temperature lowering is feasible and rational.更多还原
