沼氣的凈化一般應(yīng)包括沼氣的脫水、脫硫及脫二氧化碳。沼氣中的水分與硫化氫共同作用，能加速管道及閥門(mén)、流量計(jì)等的腐蝕，所以在進(jìn)行厭氧沼氣脫硫時(shí)， 需要同時(shí)進(jìn)行脫水處理。為了滿足小型沼氣脫硫塔程序中對(duì)沼氣濕度的要求，對(duì)高、中溫的沼氣溫度進(jìn)行適量降溫，采用旋風(fēng)式脫水法，將沼氣中的部分水蒸氣脫除。
The purification of biogas generally includes the dehydration, desulfurization and CO2 removal of biogas. The water in biogas and hydrogen sulfide act together to accelerate the corrosion of pipelines, valves and flow meters. Therefore, dehydration treatment needs to be carried out at the same time when anaerobic biogas desulfurization is carried out. In order to meet the requirements of biogas humidity in the program of small biogas desulfurization tower, the high and medium temperature biogas temperature is appropriately cooled, and the cyclone dehydration method is adopted to remove part of the water vapor in the biogas.
沼氣凈化處理原理是用氧化鐵等脫硫劑吸附除去沼氣中的氣體。目前戶用沼氣池采用小型戶用脫硫裝置，其中的脫硫劑使用半年后，可通過(guò)采用倒出脫硫劑展開(kāi)陰干法再生二次，再生后又可使用三個(gè)月，三個(gè)月后以同樣方法再生一次，總計(jì)使用期是一年。
The principle of biogas purification treatment is to remove the gas in biogas by adsorption with desulfurizer such as iron oxide. At present, the household biogas digester adopts a small household desulfurization device. After half a year of use, the desulfurizer can be regenerated by pouring out the desulfurizer and drying in the shade. After regeneration, it can be used for another three months. After three months, it can be regenerated by the same method. The total service life is one year.
當(dāng)含有硫化氫的沼氣通過(guò)小型沼氣脫硫塔脫硫劑時(shí)，沼氣中的硫化氫與脫硫劑反應(yīng)，生產(chǎn)硫化物，從而解除沼氣中的硫化氫。變成沼氣燃料。否則，含有氣體的沼氣燒飯燃燒后將會(huì)變成二氧化liu氣體不但對(duì)人體有害而且在炒菜、點(diǎn)燈時(shí)還能聞到刺鼻二氧化脫liu氣味，對(duì)人的器官造成危害，污染空氣，還會(huì)腐蝕沼氣灶、炊具等，所以，要及時(shí)更換小型沼氣脫硫塔脫硫劑是正確使用沼氣的重要措施。
When the biogas containing hydrogen sulfide passes through the desulfurizer of the small biogas desulfurization tower, the hydrogen sulfide in the biogas reacts with the desulfurizer to produce sulfide, so as to remove the hydrogen sulfide in the biogas. Into biogas fuel. Otherwise, the biogas containing gas will become oxidized Liu gas after cooking and burning, which is not only harmful to human body, but also can smell the pungent smell of oxidized Liu when cooking and lighting, which will harm human organs, pollute the air, and corrode biogas stoves and cookers. Therefore, it is an important measure to replace the desulfurizer of small biogas desulfurization tower in time.
