Description

节能型热泵式溶剂精馏系统
技术领域
本实用新型涉及一种节能型热泵式溶剂精馏系统。 
背景技术
化工生产中常常用到溶剂精馏系统,在遇到沸点较低的溶剂(如沸点为-20~50℃)时,由于普通冷却水已无法将之全部冷凝,通常需要制冷机相配合。从理论上来讲,塔底和塔顶的热量应该相等,也就是精馏塔底再沸器和塔顶冷凝器需要消耗的能量是一样多的,只不过一边是加热,一边是制冷。换句话说就是,在同一系统中,一边花能源加热,同时又花同样多的能源制冷,显然造成了能源巨大的浪费。但是在生产过程中,由于实际上精馏塔存在热损失,塔顶的热量小于塔底的热量。 
发明内容
本实用新型的目的在于提供一种结构合理,能效比高,消耗能量小的节能型热泵式溶剂精馏系统。 
本实用新型的技术解决方案是: 
一种节能型热泵式溶剂精馏系统,包括精馏塔、塔顶冷凝器,其特征是:塔顶冷凝器的热交换介质出口通过热泵与塔釜再沸器的冷凝器热交换介质进口相通,塔釜再沸器的冷凝器热交换介质出口通过热泵与塔顶冷凝器的热交换介质进口相通。 
本实用新型结构合理,有益效果还有以下三个方面: 
1、省去了塔底再沸器所需的热能,由于热泵通常的能效比可达3~5以上,且热泵与精馏塔直接组合,也减少了原制冷机制取冷冻水时一次换热损失,能效比更高,消耗的能量小于原制冷机组。 
2、当发生意外停车时,改进前再沸器用其它热源加热,也就是塔底的热源不会被同时切断,精馏塔内压力会突然增高甚至引发爆炸事故。改进后,由于加热的热量来自于热泵,精馏塔内压力不会出现突然增高的情况。装置安全性大幅度提高。 
3、与普通精馏装置相比,更易于实现自动化控制。 
附图说明
下面结合附图和实施例对本实用新型作进一步说明。 
图1是本实用新型一个实施例的结构示意图。 
具体实施方式
一种节能型热泵式溶剂精馏系统,包括精馏塔1、塔顶冷凝器2,塔顶冷凝器的热交换介质出口通过热泵3与塔釜再沸器4的冷凝器5热交换介质进口相通,塔釜再沸器的冷凝器热交换介质出口通过热泵与塔顶冷凝器的热交换介质进口相通。制冷剂可以采用F134a,溶剂的沸点为-20~50℃或其他合适的制冷剂、溶剂。
