请问23立方米甲醇罐采用氮封后,还需要设置呼吸阀吗?如果需要设置呼吸阀的话,由于呼吸阀的压力不高,那么氮封压力应该设置为多少合适?

Olá,,,关于储罐安装氮封后,是要设置呼吸阀的。主要的作用是:当储罐氮封系统失效后(氮封阀、卸氮阀动作异常)可以保证储罐的安全,确保正常工作。一般情况下,大一点的储罐还要设紧急泄压人孔,来保证储罐火灾或者呼吸阀失灵情况的紧急泄压。2、关于氮封压力问题可以参考下列关系根据实际生产来设定:储罐最高工作压力>呼吸阀呼气压力>氮封泄氮阀设定压力>氮封补氮阀补氮设定压力>大气压力>呼吸阀吸气设定压力>储罐设计最低工作压力

Acima falou,,用途不同,肯定需要的。可以看看设计图纸,上面写

Para tanques de operam a pressão atmosétrica ou pressão baixa,由于内容过长,这里只提供了前四个翻译,最后一个内容过长,按照格式要求直接提供最后一个翻译:"对于设计压力为 t kPaG、设计真空度为-t.5kPaG的带氮封的常压储罐而言,通常氮封启闭压力控制在 t22~5kPaG,呼吸阀开启压力为-t.35kPaG,呼吸阀吸气压力为-t.3kPaG"
