[化工]液氧、液氮操作规程

作者[孙锡云] 发表于[2010-9-9 16:18:00]

液氧、液氮操作规程

一、概述

1、目的:本规程指导操作人员如何正确使用液氧、液氮

2、使用设备:低温液体储槽、气化器、稳压装置

3、引用文件:

二、操作步骤

1、供气前准备工作

1.1检查储槽内压力是否正常。

1.2缓慢打开出液阀,待槽内压力至所需压力时,打开减压阀前阀。

2、供气程序

2.1压力稳定后,打开出液阀。

2.2打开蒸发器后的供气阀门,气站开始工作。

3、关闭程序

3.1关闭出液阀,增压阀。

3.2关闭减压前阀,使气站处于停用状态。

4、故障处理程序

4.1压力过高,打开放空阀降压。

4.2压力过低,打开增压阀(及增压开关)进行增压。

4.3当安全阀因压力过高而起跳时,打开放空阀,降低储槽压力,

然后关闭安全阀,密切注意储槽内的压力变化。

4.4发现漏液时,采取必要的措施,然后通知工厂设施科。

三、运行参数

1、氧气、氮气输送压力不得低于0.45Mpa,不得超过0.6Mpa

2、正常情况下出液阀和调压阀前后阀常开,放空阀常闭。

3、液量低于储量的25%时,挡班应及时通知供应商,当联系发生困难时及时汇报动力主管,联系送气。

四、维修

1、巡视人员不得随意拨弄阀门,减压装置,发现问题及时通知工厂设施科。

2、修理工作,由BOC气体公司专业维修人员进行维修。

五、巡视检查(接交班、5S工作)

1、巡视人员对液氧、液氮储槽必须做到每小时抄表一次,并作好记录。

2、加液时必须在现场监护,加液压力不能影响生产。

3、做好加液数量统计,并记录。

4、液氧、液氮储槽充液后,24小时内应密切注意储槽内的压力变化,如压力波动较大,应立即排放,保持压力正常。

5、密切注意液槽的储存量,若达到规定下限,应及时联系送气。

6、蒸发器结霜严重时,及时作好除霜工作。

六、安全措施

1、操作人员开闭阀门管道附件时,必须戴好防冻用具。

2、对于设备、管道、阀门的解冻,只能用水冲,严禁敲打,火烤和电加热。

3、液氧储槽严禁油类,严禁酸、碱、油物质接触设备。

4、液氮储槽泄漏,人员当心窒息。(放空时,尽可能远离)

5、非工作人员一律不得进入液氧、液氮区域

七、环境保护

防止泄漏、节约能源。
