沼氣脫硫器有兩種脫硫方法：濕法和干法脫硫。 干法脫硫工藝簡(jiǎn)單，成熟可靠，成本低廉，可以達(dá)到較好的凈化效果。
There are two desulfurization methods for biogas desulfurizer: wet desulfurization and dry desulfurization. The dry desulfurization process is simple, mature and reliable, with low cost, and can achieve better purification effect.
使用沼氣脫硫劑的正確方法：
Correct method of using biogas desulfurizer:
沼氣脫硫器中的氧化鐵為卡其色。 當(dāng)通過(guò)沼氣中的氫與氧化鐵之間的化學(xué)反應(yīng)產(chǎn)生的氫為灰黑色時(shí)，脫硫劑會(huì)失去其效力并被再生或替換。 將脫硫劑從瓶中倒入瓶中，首先用清水沖洗以除去沼氣引起的泥土，然后將其鋪在水泥地面上并適當(dāng)轉(zhuǎn)動(dòng)(zui可以噴灑少量稀氨水)， 使用空氣氧氣將鐵氧化為氧化鐵。 當(dāng)沼氣脫硫劑由灰黑色變?yōu)榭ㄆ渖珪r(shí)，再生過(guò)程完成。 如果自制脫硫劑再生兩次，則應(yīng)更換新的脫硫劑。
The iron oxide in the biogas desulfurizer is khaki. When the hydrogen generated by the chemical reaction between hydrogen in biogas and iron oxide is gray black, the desulfurizer will lose its effectiveness and be regenerated or replaced. Pour the desulfurizer from the bottle into the bottle, first wash it with clean water to remove the mud caused by biogas, then spread it on the cement floor and rotate it properly (zui can spray a small amount of dilute ammonia water), and use air oxygen to oxidize iron into iron oxide. When the biogas desulfurizer changes from gray black to khaki, the regeneration process is completed. If the self-made desulfurizer is regenerated twice, replace it with a new one.
沼氣提純
Biogas purification
值得注意的是，當(dāng)從水壓中排出沼氣池時(shí)，拔下沼氣脫硫器的進(jìn)氣管。 避免在沼氣池中產(chǎn)生負(fù)壓，并迅速將大量空氣從出氣管返回到沼氣脫硫器中。 此時(shí)，脫硫劑將經(jīng)歷劇烈的再生(氧化)過(guò)程，并且化學(xué)反應(yīng)產(chǎn)生相對(duì)較高的溫度。
It is worth noting that when the biogas digester is discharged from the water pressure, the inlet pipe of the biogas desulfurizer is pulled out. Avoid negative pressure in the biogas digester, and quickly return a large amount of air from the outlet pipe to the biogas desulfurizer. At this time, the desulfurizer will undergo a severe regeneration (oxidation) process, and the chemical reaction will produce a relatively high temperature.
沼氣脫硫劑的維護(hù)與保養(yǎng)：
Maintenance of biogas desulfurizer:
使用一段時(shí)間后，脫硫器中的脫硫劑會(huì)變黑，失去活性，降低脫硫效果，還可能打結(jié)，增加了沼氣輸送的阻力。 在嚴(yán)重的情況下，沼氣將被阻塞且無(wú)法通過(guò)。 此時(shí)，使脫硫劑再生。
After a period of use, the desulfurizer in the desulfurizer will become black, lose its activity, reduce the desulfurization effect, and may also knot, increasing the resistance of biogas transmission. In serious cases, biogas will be blocked and cannot pass through. At this time, the desulfurizer is regenerated.
再生方法：將失活的脫硫劑取出，均勻松散地堆放在平坦，清潔，背陽(yáng)的通風(fēng)處，并經(jīng)常翻轉(zhuǎn)脫硫劑使其與空氣充分接觸以進(jìn)行氧化再生。 當(dāng)脫硫劑的水分含量低時(shí)，可以均勻地噴霧稀釋的堿溶液以加快再生速度并縮短再生時(shí)間。 通常，約一個(gè)月后，它可用于脫硫器中。 脫硫劑可再生1或2次。
Regeneration method: take out the deactivated desulfurizer, and stack it evenly and loosely in a flat, clean and sunny ventilated place, and often turn over the desulfurizer to make it fully contact with the air for oxidative regeneration. When the moisture content of the desulfurizer is low, the diluted alkali solution can be evenly spray to accelerate the regeneration speed and shorten the regeneration time. Generally, it can be used in the desulfurizer after about a month. Desulfurizer can be regenerated once or twice.
