沼氣脫硫脫水設(shè)備具有效率高、體積小、安裝使用方便、內(nèi)部的不銹鋼絲網(wǎng)可反復(fù)清洗、當(dāng)沼氣中的硫化氫與氧化鐵接觸起化學(xué)反應(yīng)生成的硫化鐵呈灰黑色時，脫硫劑失去效力，則要再生或更換。將失效的脫硫劑從瓶內(nèi)倒出，先用清水沖洗以去除由沼氣帶來的泥沫因為沼氣中含有大量的硫化氫常用的干法脫硫有活性炭法、氧化鐵法、氧化鋅。三個月后應(yīng)進(jìn)行再生或更換脫硫劑，對沼氣的利用影響很大，對環(huán)境、設(shè)備、管道以及儀表等產(chǎn)生污染和腐蝕的影響，所以沒有經(jīng)過凈化的沼氣是不能使用的。
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.
沼氣脫硫器沼氣脫硫罐運行原理：
Operation principle of biogas desulfurization tank of biogas desulfurizer:
沼氣脫硫脫水設(shè)備其次水分部分泡爛氧化鐵顆粒但仍能留存部分出氣孔；再次在于多孔管懸空設(shè)置，使脫硫瓶內(nèi)水分積存在懸空多孔管下。優(yōu)點是既能脫除硫化氫、又能脫除有機硫,凈化度較濕法脫硫高,可將氣體中H2S脫至20mg/m3以下，常用的干法脫硫有活性炭法、氧化鐵法、氧化鋅。脫硫劑倒出后先除去碎沫，再將顆粒型的脫硫劑放在水泥地面或鐵板上、對環(huán)境、設(shè)備、管道以及儀表等產(chǎn)生污染和腐蝕的影響、將失效的脫硫劑從瓶內(nèi)倒出，先用清水沖洗以去除由沼氣帶來的泥沫，然后攤曬在水泥地面上并適當(dāng)翻曬（能噴灑少量的稀氨水），利用空氣中的氧氣將硫化鐵又氧化成氧化鐵。
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.
