沼氣脫硫是沼氣工程的難點，傳統(tǒng)的濕法脫硫過程會消耗大量的水，而沼氣生物脫硫設(shè)備、生物沼氣脫硫器的反應(yīng)過程中會生成水，大大減少了水的消耗。我們一起來看看沼氣生物脫硫設(shè)備、生物沼氣脫硫器是怎么工作的吧！
Biogas desulfurization is the difficulty of biogas engineering. The traditional wet desulfurization process will consume a lot of water, while the reaction process of biogas biological desulfurization equipment and biogas desulfurizer will generate water, which greatly reduces the water consumption. Let's take a look at how biogas biological desulfurization equipment and biogas desulfurizer work!
沼氣生物脫硫設(shè)備、生物沼氣脫硫器原理介紹
Principle introduction of biogas biological desulfurization equipment and biogas desulfurizer
將一定量的空氣引入含硫化氫的沼氣中，并在反應(yīng)器中安裝大量生物填料，為細菌生長提供足夠的空間。營養(yǎng)液（NPK）的循環(huán)可保持填料濕潤，并補充細菌生長和繁殖所需的營養(yǎng)。專有棒桿菌和硫桿菌屬在代謝過程中吸收硫化氫，將其轉(zhuǎn)化為元素硫，再將其轉(zhuǎn)化為硫酸。
A certain amount of air is introduced into the biogas containing hydrogen sulfide, and a large number of biological fillers are installed in the reactor to provide sufficient space for bacterial growth. The circulation of nutrient solution (NPK) can keep the filler moist and supplement the nutrients required for bacterial growth and reproduction. Proprietary Corynebacterium and Thiobacillus absorb hydrogen sulfide during metabolism, convert it into elemental sulfur, and then convert it into sulfuric acid.
在營養(yǎng)液的緩沖和中和作用下，將得到的稀硫酸與營養(yǎng)液一起從系統(tǒng)中排出，并重復(fù)此過程。
Under the buffering and neutralizing action of the nutrient solution, the obtained dilute sulfuric acid is discharged from the system together with the nutrient solution, and the process is repeated.

Progress analysis of biogas biological desulfurization equipment and biogas desulfurizer
沼氣進入反應(yīng)器的底部，并從底部到頂部穿過填充層。通過變頻控制準確添加空氣。廢氣成分分析儀監(jiān)測殘留的氧氣濃度，并與鼓風(fēng)機一起工作。營養(yǎng)液通過計量泵定期添加。液位開關(guān)控制整體液位平衡。
Methane enters the bottom of the reactor and passes through the filling layer from bottom to top. Add air accurately through frequency conversion control. The exhaust gas composition analyzer monitors the residual oxygen concentration and works with the blower. Nutrient solution is added regularly by metering pump. The liquid level switch controls the overall liquid level balance.
為了確保細菌的佳活性，使用熱交換器和溫度監(jiān)控器來調(diào)節(jié)和控制系統(tǒng)溫度。 PH計用于控制營養(yǎng)液的質(zhì)量（酸度）。例如，如果pH值低于設(shè)定值，則將新鮮的營養(yǎng)液和稀釋水自動添加到脫硫塔中。同時，廢液自動排出，液位達到平衡。
In order to ensure the good activity of bacteria, heat exchangers and temperature monitors are used to regulate and control the system temperature. PH meter is used to control the quality (acidity) of nutrient solution. For example, if the pH value is lower than the set value, fresh nutrient solution and dilution water will be automatically added to the desulfurization tower. At the same time, the waste liquid is discharged automatically, and the liquid level is balanced.
