【技术实现步骤摘要】
吸收式扩容器
本技术提供的是热能领域的热回收利用设备,主要应用于锅炉排污水余热回收。具体地说是吸收式扩容器。
技术介绍
目前,锅炉在运行中为了排出锅水中的各种可溶性和不溶性杂质,控制锅炉水质,锅炉必须进行排污。锅炉排污一般分为连续排污和定期排污,排放的污水一般直接排放,或经扩容器减温减压后排放。扩容器是用来将锅炉的排污减压扩容,排污水在膨胀器内膨胀分离为二次蒸汽和废热水,二次蒸汽由专门的管道引出,废热水一般经排污降温池排入下水系统。传统的扩容器仅仅满足了锅炉排污的需求,大量的废热、废水被直接排放,造成能源的浪费。锅炉在实际运行中,排污率可以达到锅炉蒸发量的1%~3%,如果能够回收利用这部分废水的热量将有效地提高锅炉的运行效率。
技术实现思路
为了能够解决锅炉定期和连续排放污水余热回收利用的问题,本技术提供了吸收式扩容器。该扩容器通过在扩容器后续设置吸热器,解决锅炉排污水与余热回收的技术问题。本技术解决技术问题所采用的方案是:在扩容器上部一侧连接有锅炉排污水管路,下部连接有排污管路,扩容器内具有水层和气层,在扩容器上端与气层连接有蒸汽管路,在扩容器水层连接有热水管路,蒸汽管路与热水管路汇聚通过热水管路与吸热器连通,热水管路上装有阀门、压力表和温度计,在吸热器内设有热交换板,左侧为供热端,右侧为换热端,在吸热器换热端上部连接有锅炉补水出水管路,在吸热器换热端下部连接有锅炉补水进水管路,在供热端下部连接有冷水管路,冷水管路置于储水池上部。积极效果,由于本技术采用扩容器与吸热器相结合,利用扩容器自身内压、气体流动动能,实现汽、水分离再汇集进入吸热器,排污水中热量完全回 ...
