精馏酒精设备中废热的有效利用

Effective use of waste heat in rectifying alcohol equipment

在酒精生产过程中,精馏工序的能耗最大,通过回收利用精馏环节所产生的余热,不仅能实现能源回收利用,而且还能够有效控制热能污染问题。精馏节能方法有很多种,其中热泵精馏的热回收利用效果最好。对此,首先对酒精精馏工艺流程进行了介绍,然后对热泵精馏技术进行了分析,并对此技术在废热回收中的应用方式进行详细探究。

The energy consumption of distillation process is most highest in the process of alcohol producion.Recycling of wasteheat produced in distillation process could not only realize energy reusing but also control thermal energy polltion.There are manykinds of energy saving methods for distillation.Heat pump distillation is the best method of heat recovery.Firstly,the paper introducedthe process of alcohol distillation,then analyzed the technology of heat pump distillation.At last,the the application of the tecnology inwaste heat recovery is discussed.
