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。
The biogas desulfurization and dehydration equipment has 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 the chemical reaction is grayish black, the desulfurization agent loses its effectiveness and needs to be regenerated or replaced.
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。
Pour out the ineffective desulfurizer from the bottle and rinse it with clean water to remove the sludge brought by biogas. Due to the large amount of hydrogen sulfide in biogas, commonly used dry desulfurization methods include activated carbon method, iron oxide method, and zinc oxide method. After three months, regeneration or replacement of desulfurizers should be carried out, which has a significant impact on the utilization of biogas and causes pollution and corrosion to the environment, equipment, pipelines, and instruments. Therefore, untreated biogas cannot be used.
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。
Secondly, the methane desulfurization and dehydration equipment can soak up iron oxide particles in the water, but still retain some air vents; Once again, the porous tube is set up in the air, so that the moisture accumulation inside the desulfurization bottle exists under the suspended porous tube. The advantage is that it can remove both hydrogen sulfide and organic sulfur, with higher purification compared to wet desulfurization. It can remove H2S from the gas to below 20mg/m3. Commonly used dry desulfurization methods include activated carbon method, iron oxide method, and zinc oxide method.
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。
After pouring out the desulfurizer, remove the broken foam first, and then place the granular desulfurizer on the cement floor or iron plate to cause pollution and corrosion to the environment, equipment, pipelines, and instruments. Pour out the ineffective desulfurizer from the bottle, rinse with clean water to remove the mud foam brought by biogas, and then spread it on the cement floor and turn it over appropriately (can spray a small amount of dilute ammonia water), Using oxygen in the air to oxidize iron sulfide back into iron oxide.
