管道防冻
Reply #42017-02-14
冬季排水,离地4.5米,打算接个dn45的管道排水,考虑到管道防冻方面的影响,除了作伴热,加保温之外,还有什么更省事的方法? 我们曾经1小时排一次水,管道还冻住了后来加电伴热,好多了,最近又要加管排水,不得不考虑排水防冻方面的问题。 我就想有没有不用加伴热的方法?管道里面是水,管道本身换热不好,管道是不是就不冻了?

主要是加强保温伴热,是否可以让管道里的水出来后及时排尽

苦恼的是,水是可以排尽的,但是水的来源是乙炔气体中的水分,冷凝下来的,只要产气,就会有,也提醒了我一点,管道水会一直有。我们把的只是管线里的水。

建议采取保温+电伴热方式,另外在管道设计上,尽量成有一定斜度,或者考虑低点放空

没有好的办法,蒸汽或电伴热就是最直接、行之有效的办法。
