The biogas desulfurization and dehydration equipment is characterized by high efficiency, small size, convenient installation and use, and the internal stainless steel wire mesh can be repeatedly cleaned. When the hydrogen sulfide in the biogas contacts with iron oxide and the iron sulfide generated by chemical reaction is gray black, the desulfurizer will lose its effectiveness, and it will be regenerated or replaced. Pour out the ineffective desulfurizer from the bottle, and wash it with clean water to remove the mud foam brought by the biogas. Because the biogas contains a large amount of hydrogen sulfide, the commonly used dry desulfurization methods include activated carbon method, iron oxide method and zinc oxide method. Regeneration or replacement of desulfurizer should be carried out after three months, which has a great impact on the utilization of biogas, and has a pollution and corrosion impact on the environment, equipment, pipelines and instruments. Therefore, biogas without purification cannot be used.

Operation principle of biogas desulfurization tank of biogas desulfurizer:

yl6809永利脱水设备其次水分部分泡烂氧化铁颗粒但仍能留存部分出气孔；再次在于多孔管悬空设置，使脱硫瓶内水分积存在悬空多孔管下。优点是既能脱除硫化氢、又能脱除有机硫,净化度较湿法脱硫高,可将气体中H2S脱至20mg/m3以下，常用的干法脱硫有活性炭法、氧化铁法、氧化锌。脱硫剂倒出后先除去碎沫，再将颗粒型的脱硫剂放在水泥地面或铁板上、对环境、设备、管道以及仪表等产生污染和腐蚀的影响、将失效的脱硫剂从瓶内倒出，先用清水冲洗以去除由沼气带来的泥沫，然后摊晒在水泥地面上并适当翻晒（能喷洒少量的稀氨水），利用空气中的氧气将硫化铁又氧化成氧化铁。

The second part of the biogas desulfurization and dehydration equipment is that the water partially bubbles the iron oxide particles, but still retains part of the air outlet; Thirdly, the porous pipe is suspended to make the water in the desulfurization bottle accumulate under the suspended porous pipe. The advantages are that it can remove both hydrogen sulfide and organic sulfur, and the purification degree is higher than that of wet desulfurization. It can remove H2S in the gas to less than 20mg/m3. The commonly used dry desulfurization methods include activated carbon method, iron oxide method and zinc oxide method. After the desulfurizer is poured out, the foam shall be removed first, and then the granular desulfurizer shall be placed on the cement floor or iron plate, which will cause pollution and corrosion to the environment, equipment, pipelines and instruments, etc. The ineffective desulfurizer shall be poured out of the bottle, washed with clean water to remove the mud foam brought by the biogas, and then spread on the cement floor and properly turn the sun (a small amount of dilute ammonia water can be sprayed), Use oxygen in the air to oxidize iron sulfide into iron oxide.
