利用沼氣脫硫技術(shù)制作的設(shè)備有哪些?

沼氣脫硫是將沼氣中的硫化氫(H2S)等有毒有害氣體去除的過程,常用的沼氣脫硫設(shè)備主要有以下幾種:

Biogas desulfurization is the process of removing toxic and harmful gases such as hydrogen sulfide (H2S) from biogas. The commonly used biogas desulfurization equipment mainly includes the following types:
1. 濕法脫硫設(shè)備:包括氧化吸收法、堿液吸收法和生物脫硫法。氧化吸收法適用于高濃度H2S氣體的脫硫,采用氧化劑,如氯酸鈉或氯酸鈣,使H2S氧化為硫酸鹽溶液,然后再用堿液吸收法洗滌得到清潔的沼氣。堿液吸收法采用強堿(如鈉氫氧化物)溶液吸收H2S,生成硫化物沉淀,再用氧化劑氧化成元素硫進行回收。生物脫硫法則通過微生物代謝能力去除H2S,常用的微生物包括硫酸鹽還原菌、亞硝酸鹽還原菌等。
1. Wet desulfurization equipment: including oxidation absorption method, alkali absorption method, and biological desulfurization method. The oxidation absorption method is applicable to the desulfurization of high concentration H2S gas. The oxidant, such as Sodium chlorate or Calcium chlorate, is used to oxidize H2S into sulfate solution, and then the alkaline solution absorption method is used to wash clean biogas. The alkali absorption method uses a strong alkali (such as sodium hydroxide) solution to absorb H2S, generate sulfide precipitates, and then oxidize them with oxidants to form elemental sulfur for recovery. The biological desulfurization principle removes H2S through the metabolic capacity of microorganisms, including sulfate reducing bacteria, nitrite reducing bacteria, etc.
2. 干法脫硫設(shè)備:主要有活性炭吸附法和干式脫硫法?;钚蕴课椒ɡ没钚蕴繉2S進行吸附,將其轉(zhuǎn)化為硫化物。干式脫硫法常用的是氧化劑,如氧氣或過氧化鐵,在催化劑作用下將H2S氧化生成硫,然后把沼氣與催化劑反應(yīng)得到清潔的沼氣。

2. Dry desulfurization equipment: mainly including activated carbon adsorption method and dry desulfurization method. The activated carbon adsorption method utilizes activated carbon to adsorb H2S and convert it into sulfides. The commonly used dry desulfurization method is an oxidant, such as oxygen or iron peroxide, which oxidizes H2S to produce sulfur under the action of a catalyst, and then reacts with the catalyst to obtain clean biogas.
以上是常見的沼氣脫硫設(shè)備,不同設(shè)備適用于不同的脫硫規(guī)模和處理要求,請根據(jù)具體情況選擇適合的設(shè)備。另外,根據(jù)沼氣含硫量的不同,可能需要結(jié)合使用多種脫硫設(shè)備進行處理。
The above are common biogas desulfurization equipment, which are suitable for different desulfurization scales and treatment requirements. Please choose the appropriate equipment according to the specific situation. In addition, depending on the sulfur content of biogas, it may be necessary to combine multiple desulfurization equipment for treatment.
