    有毒气体报警器如何选择?

    文章出处:未知 作者:admin人气: admin 发表时间:2019-07-04 21:53
    在很多炼油厂、化工厂中,设备中有毒(有毒气体报警器)和爆炸(可燃气体报警器)气体的释放是经常存在的,而由于气体的可流动性,一个区域的危险气体释放会很快扩散到其它区域,而在遇到密闭空间的结构时,这些气体就可能通过扩散、渗透、下沉等方式进入密闭空间,因此在决定密闭空间进入的有毒有害气体检测方法时,要充分考虑到所有可能的发生情况。气体报警器在设计时要根据这些气体的产生原因来设计,这些原因大致包括:空间中的自然过程(比如分解、腐烂等);与密闭空间相关的工作过程;在空间中使用的或产生的物质;外在污染源等。
