在对双膜气柜进体置换时的注意事项!

双膜气柜是一种用来储存沼气、氧气、二氧化碳等中性气体的设备,双膜气柜有着防腐性能高、易于安装等特点,在双膜气柜进体置换时有哪些注意事项需要我们注意呢?下面潍坊锦爵环保小编简单给大家介绍下:

Double membrane gas holder is a device used to store neutral gases such as biogas, oxygen, carbon dioxide, etc. Double membrane gas holder has high anti-corrosion performance and is easy to install. What precautions should we pay attention to when replacing gas in double membrane gas holders? Below is a brief introduction by Weifang Jinjue Environmental Protection Editor:
煤气和沼气的气体置换多采用氮气,可是氮气的气体置换成本高而且置换速度也慢,因此有些厂家会选择使用空气置换,不但成本低而且置换速度还快,不过采用空气置换需注意以下几点:
Nitrogen is often used for gas replacement of gas and biogas, but the cost of nitrogen gas replacement is high and the replacement speed is also slow. Therefore, some manufacturers choose to use air replacement, which not only has low cost but also fast replacement speed. However, when using air replacement, the following points should be noted:
沼气脱硫
(1)气柜的放气阀应控制放气速度,放气速度太快,气体易和钢板摩擦发生火花,构成严重后果。
(1) The air release valve of the gas cabinet should control the air release speed. If the air release speed is too fast, the gas can easily rub against the steel plate and cause sparks, which can cause serious consequences.
(2)定期检测出气的含氧量,保证沼气含量在允许范围内。
(2) Regularly test the oxygen content of the gas to ensure that the biogas content is within the allowable range.
(3)选择适当的鼓风机,主要考虑的是鼓风机里的风压跟风量。风压过低,气柜较难上升,而风压太高,气柜上升又会太快;风量太小,气柜上升慢。因此要根据气柜的平衡压力及容积确定鼓风机的型号。
(3) When selecting an appropriate blower, the main consideration is the air pressure and air volume inside the blower. If the wind pressure is too low, it is difficult for the gas holder to rise, while if the wind pressure is too high, the gas holder will rise too quickly; The air volume is too small, and the gas cabinet rises slowly. Therefore, the model of the blower should be determined based on the balance pressure and volume of the gas holder.
(4)气柜气体置换应先开钟罩周边的阀门,先置换沼气,再开钟罩中间的阀门,置换中间气体,这才能保障气柜内没有死角位置。
(4) Gas replacement in the gas cabinet should first open the valves around the bell cover, replace the biogas, and then open the valves in the middle of the bell cover to replace the middle gas, in order to ensure that there are no dead corners in the gas cabinet.
