常压储罐不是安装安全阀,他的紧急泄放系统是泄压人孔,一般设置氮封、呼吸阀及泄压人孔。

你好,首先完整的氮封系统是包括:氮封补氮阀和卸氮阀两部分的,整个氮封储罐的安全系统按压力低至高排列为:卸氮阀、呼吸阀、紧急泄压人孔,一般储罐的紧急泄压人孔是考虑火灾情况下物料剧烈蒸发所开启的,所以氮封储罐一般不设安全阀,关于安全阀的起跳压力我们可以认为是:储罐的设计压力≥储罐的最高工作压力≥安全阀的起跳压力

一般甲醇设常压罐(-0.5~2KPa),氮封压力不用考虑那么高,用氮封0.5KPa+呼吸阀1.375KPa+紧急泄压人孔1.8Kpa就够了。

液压安全阀起跳压力可以几个kpa吗?
Reply #72022-05-30
550~1960,-490Pa

同意4楼的观点,如果要设置安全阀必须要满足储罐也是压力容器,如果是常压容器那么没有必要设置安全阀。安全阀一般是用在压力容器和压力管道上面的比较多。

重力安全阀也是一个选择,工艺包是怎么规定的?
