["再生器外部需要保温涂层吗?
Reply #32018-09-10
-再生器外部有涂过热变色涂料的还有涂保温涂层的。保温涂层能回收多少热能?各装置都是怎样做的欢迎大家积极讨论。

-再生器内部一般都是衬隔热、耐磨衬里,外壁绝大多数都不需要做保温的。

-我看到的化工厂里的都是外面涂的是过热变色涂料外面需要做保温。

-本帖最后由 longziyun 于 228-8-11 23:18 编辑 再生器图里见过的的还真没见过还要保温的。这个热量散失也没见过回收的。设计规范里也没见过。只见过烤烤瓜的。反再两器本身就不规则,器壁内工艺、仪表和公用工程开口较多,所连接管道、阀门和测量仪表十分复杂,还包括再生、待生、循环斜管、外取热器、滑阀等等异形设备。多数法兰与器壁挨得较近,增加保温厚度后无法进行有效的检查、检测或维修工作。更主要的是保温后就无法及时发现两器热点及时进行补救。等造成70度以上的高温催化剂严重泄露后。后果将不堪设想。

-外部不打保温而是刷耐高温的防锈漆。
