塔器设备人孔打开的顺序问题
Reply #42017-05-21
塔器设备人孔打开的顺序问题,是从上往下还是从下往上?为什么会有这样的的要求?
Reply #52017-05-21
在打开塔人孔前应该是停工处理结束状态,此时塔内可能还会积存一些工艺介质,挥发出有毒有害气体。 按照“烟囱效应”原理应该先开顶部人孔,再逐一向下开人孔。塔内的挥发气体就会上升从上部人孔排出防止伤人。

主要考虑是通气的原因,开封之前是密闭的,若从下往上开,最上面的人孔很难打开,因为里面有高浓度的有毒有害气体,先从上面开,里面不对流,所以有毒气体不容易出来利于开人孔,封人孔是同样的道理。

都是从上往下。防止人员伤害

从上往下,防止下部氧气不足,或者其他物质沉积让人窒息

烟囱效应下安全,作业规程制度

先开上面热对流通少少很多,反之上面很难开。

自上而下一方便一安全通风

从上至下、安全考虑、如果先开下面、里面有毒有害气体容易造成人员中毒或者窒息、这样的的事故案例发生不少
