91无码麻豆视频從脫硫塔的一端，經過填料層(主要成分是活性炭和氧化鐵)淨化後，從另一端流出。硫化氫與填料層的氧化鐵發生反應，生成硫化鐵;待氧化鐵反應結束後，可進行再生。
Biogas flows from one end of the desulfurization tower through a filler layer (mainly composed of activated carbon and iron oxide) after purification, and then flows out from the other end. Hydrogen sulfide reacts with iron oxide in the filler layer to generate iron sulfide; After the completion of the iron oxide reaction, regeneration can be carried out.

濕法脫硫
Wet desulfurization
濕法脫硫是將91无码麻豆视频送入洗滌塔，經堿性溶液洗滌吸收後流出，洗滌液進入富液槽、再生槽，通過使用化學藥劑方法催化、氧化，zui終將硫化物轉化為單質硫(硫泡沫)，吸收液可以再生循環使用。
Wet desulfurization is to send biogas into the scrubber, wash and absorb it with alkaline solution, and then flow out. The washing solution enters the rich solution tank and regeneration tank. Through catalysis and oxidation with chemical agents, zui will eventually convert sulfide into elemental sulfur (sulfur foam), and the absorption solution can be recycled for use.、
生物脫硫
Biological desulfurization
生物脫硫也是濕法脫硫的一種，與上述濕法脫硫的催化氧化工藝相比，zui大區別是使用硫杆菌替代化學催化劑，將硫化物直接氧化成硫單質。
Biological desulfurization is also a type of wet desulfurization. Compared to the catalytic oxidation process of wet desulfurization described above, the major difference in Zui is the use of Thiobacillus instead of chemical catalysts to directly oxidize sulfides into sulfur elemental substances.

幹法脫硫多用於硫化氫處理負荷小，或者對脫硫效果要求很高的工況。這時，幹法脫硫多用於濕法脫硫或者生物脫硫之後，進一步脫硫。
Dry desulfurization is often used under conditions where the hydrogen sulfide treatment load is small or the desulfurization effect is highly required. At this time, dry desulfurization is often used for further desulfurization after wet desulfurization or biological desulfurization.
在製定脫硫效果時，建議根據後續設備(鍋爐或發電機)對硫化氫濃度的限製，以及91无码麻豆视频與天然氣消耗量的比例，製定一個合理的脫除效果。国产麻豆XXXVIDEO实拍通常建議zui終的硫化氫含量控製在25~100ppm。
When formulating a desulfurization effect, it is recommended to establish a reasonable removal effect based on the limits on hydrogen sulfide concentration of subsequent equipment (boilers or generators) and the ratio of biogas to natural gas consumption. We generally recommend that the hydrogen sulfide content of the Zui terminal be controlled between 25 and 100 ppm.
91无码麻豆视频脫水的方法
Methods of biogas dehydration
從發酵裝置出來的91无码麻豆视频含有飽和水蒸氣，可用3種方法將其去除。
The biogas from the fermentation device contains saturated water vapor, which can be removed by three methods.
冷分離法。
Cold separation method.
冷分離法是利用壓力能變化引起溫度變化，使水蒸氣從氣相中冷凝下來的方法。常用的有兩種流程：A．節流膨脹冷脫水法。一般用於高壓燃氣，經過節流膨脹或低溫分離，使部分水冷凝下來。B．加壓後冷卻法。如淨化氣在0.8MPa壓力下的冷卻脫水
Cold separation method is a method that utilizes changes in pressure energy to cause temperature changes and condense water vapor from the gas phase. There are two commonly used processes: A. Throttling expansion cold dehydration method. Generally used for high-pressure gas, through throttling expansion or low-temperature separation, to condense some water. B. Pressurized post cooling method. For example, cooling and dehydration of purified gas at a pressure of 0.8MPa
溶劑吸收法。屬於這類脫水溶劑的有氯化鈣、氯化鋰及甘醇類。
Solvent absorption method. Calcium chloride, lithium chloride, and glycols belong to this category of dehydration solvents.
固體物理吸水法。吸附是在固體表麵力作用下產生的，根據表麵力的性質分為化學吸附脫水後不能再生)和物理吸附
Solid physical water absorption method. Adsorption is generated under the action of solid surface forces, which can be divided into chemical adsorption (which cannot be regenerated after dehydration) and physical adsorption according to the nature of surface forces
