目前,我国发酵酒精生产过程中能源消耗比较大。本文以发酵酒精生产过程中用蒸汽量较大的蒸馏系统进行分析,采用热水制冷技术,将预热进行回收,给热水制冷机组进行制冷,一是对原预热进行二次利用,二是减少开启制冷机组,降低制冷机组电耗,达到降低能源消耗的目的。 At present, China’s fermentation of alcohol production process energy consumption is relatively large. In this paper, the production process of fermented ethanol with a large amount of steam distillation system analysis, the use of hot water cooling technology, the preheating recovery, hot water cooling unit for refrigeration, the first preheat secondary use, two Is to reduce the opening of refrigeration units, reduce power consumption refrigeration units, to reduce energy consumption purposes.
