安装蒸汽疏水阀能实现节能吗？

日期： 2024-10-16 作者：晟德亿编辑

蒸汽向物体施热后会失去热量，凝结后恢复到热水。这种凝结后的水就叫做冷凝水。对于蒸汽输送管道或者使用蒸汽的机器来说，冷凝水的存在是一种损失，需要即时排出。

1.冷凝水如存在蒸汽系统内会降低热效率

因为蒸汽把所含有潜热传导给对象物体后变成冷凝水，冷凝水含有热量远远小于蒸汽，降低热传导效率。因此需要把冷凝水迅速从蒸汽系统排出，但冷凝水也含有有效热能，可进行二次利用。

2.空气及 Coz 的排放

设备启动时以及锅炉补水中溶解有空气。另外锅炉供水中有可能含有碳酸盐成分，分解产生 CO2.空气附着于管道内壁将会大幅度降低了热传导效率。并且蒸汽里含有空气后,会造成饱和温度下降导致热效率低下。CO2会变化称为具有腐蚀性的酸化物，腐蚀管道与热交换器，因此，一定要从管道中排除这些非压缩性气体。

3.防止水锤

在管道中，冷凝水积聚于管道底部，被高速流动的蒸汽推动。冷凝水如不及时排除，在管道底端会形成波浪，逐渐升高到达管道顶端，这时被高速流动的蒸汽推动行进撞击阀门或管道弯曲配管部分，形成巨大的撞击声音。我们把这种现象称为水锤，水锤不仅会产生噪音，还会造成管道接头弯曲，泄漏，阀门破损等情况。为了防止水锤冷凝水的排放至关重要。
