净化风中断的处理

答案

参考答案:

处理办法

1、联系调度及空压站,查明原因。

2、立即将非净化风引入风罐,风罐加强脱水。

3、如非净化风也中断,则要作如下处理:

(1)根据调节阀的风开风关,立即切换手动。控制阀用副线阀或上下游阀控制。

(2)参考机泵电流、压力表、温度计、流量一次表、初馏塔和常压塔玻璃液面板、减压塔底浮球等参数,综合分析,维持正常生产。要确保不超温、不超压、不着火、不爆炸、不冲塔、不跑油。容器、塔界位要专人看好。

(3)请示调度,将特种油口改罐。

(4)有的装置,因仪表没有指示,而新工人多,操作经验少,手动操作甚乱,易出事故,因此一般停风时间过长,则按降温循环处理,等功夫后再恢复正常生产。
