雙膜氣柜是一種用來儲存沼氣、氧氣、二氧化碳等中性氣體的設(shè)備，雙膜氣柜有著防腐性能高、易于安裝等特點，在雙膜氣柜進(jìn)行氣體置換時有哪些注意事項需要我們注意呢?下面濰坊錦爵環(huán)保小編簡單給大家介紹下：
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:
煤氣和沼氣的氣體置換多采用氮氣，可是氮氣的氣體置換成本高而且置換速度也慢，因此有些廠家會選擇使用空氣置換，不但成本低而且置換速度還快，不過采用空氣置換需注意以下幾點：
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:
（1）氣柜的放氣閥應(yīng)控制放氣速度，放氣速度太快，氣體易和鋼板摩擦發(fā)生火花，構(gòu)成嚴(yán)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）定期檢測出氣的含氧量，保證沼氣含量在允許范圍內(nèi)。
(2) Regularly test the oxygen content of the gas to ensure that the biogas content is within the allowable range.
（3）選擇適當(dāng)?shù)墓娘L(fēng)機，主要考慮的是鼓風(fēng)機里的風(fēng)壓跟風(fēng)量。風(fēng)壓過低，氣柜較難上升，而風(fēng)壓太高，氣柜上升又會太快；風(fēng)量太小，氣柜上升慢。因此要根據(jù)氣柜的平衡壓力及容積確定鼓風(fēng)機的型號。
(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）氣柜氣體置換應(yīng)先開鐘罩周邊的閥門，先置換沼氣，再開鐘罩中間的閥門，置換中間氣體，這才能保障氣柜內(nèi)沒有死角位置。
(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.
