近年來，隨著我國社會的發(fā)展，國內(nèi)經(jīng)濟(jì)水平的不斷提高，人們生活水平逐步提升，沼氣的使用現(xiàn)象已經(jīng)越來越普遍。沼氣雖好，但是含有有毒有害氣體硫化氫，由于硫化氫有毒、腐蝕性很強(qiáng)，對人們身體有著很大的危害，因此，如何有效且經(jīng)濟(jì)地處理這些沼氣中的有毒有害氣體--硫化氫，是衡量一個沼氣利用項(xiàng)目成功的重要因素。無錫市諾帕爾生物科技有限公司就是一家主營從事沼氣脫硫工程的高新技術(shù)企業(yè)，現(xiàn)如今，隨著科技的發(fā)展、技術(shù)的更替，沼氣脫硫技術(shù)已發(fā)展到以生物脫硫?yàn)榇淼恼託饷摿蚣夹g(shù)。其中生物脫硫又大體分為一體式生物脫硫和分離式生物脫硫這兩種脫硫方式。
In recent years, with the development of China's society, the continuous improvement of domestic economic level, people's living standards have gradually improved, the use of biogas has become more and more common. Although biogas is good, it contains poisonous and harmful gas hydrogen sulfide. Because hydrogen sulfide is toxic and corrosive, it has great harm to people's health. Therefore, how to effectively and economically deal with the poisonous and harmful gas hydrogen sulfide in biogas is an important factor to measure the success of a biogas utilization project. Wuxi nuopal Biotechnology Co., Ltd. is a high-tech enterprise mainly engaged in biogas desulfurization project. Nowadays, with the development of science and technology and the replacement of technology, biogas desulfurization technology has developed to the biogas desulfurization technology represented by biological desulfurization. Among them, biological desulfurization is generally divided into integrated biological desulfurization and separated biological desulfurization.
在一體式生物脫硫和分離式生物脫硫這兩種脫硫方式中，一體式生物脫硫是指：將一定量的空氣導(dǎo)入含有硫化氫的沼氣中，這種混合氣體會通過生物濾池、生物滴濾池以去除硫化氫，脫硫副產(chǎn)物一般為硫酸或者硫酸鹽。由于一體式生物脫硫技術(shù)運(yùn)行的成本非常低，所以現(xiàn)如今，被廣泛應(yīng)用于沼氣脫硫發(fā)電項(xiàng)目中，發(fā)展前景廣闊。
In the integrated biological desulfurization and separate biological desulfurization, the integrated biological desulfurization refers to that a certain amount of air is introduced into the biogas containing hydrogen sulfide, and the mixed gas will be removed by biological filter and biotrickling filter, and the by-product of desulfurization is generally sulfuric acid or sulfate. Because the operation cost of integrated biological desulfurization technology is very low, so now, it is widely used in biogas desulfurization power generation project, and has broad development prospects.
其中的分離式生物脫硫工藝指的是含硫化氫的沼氣氣體在進(jìn)入生物洗滌塔內(nèi)后，在塔內(nèi)與堿起到反應(yīng)，先從沼氣中脫除硫化氫，然后生物洗滌液進(jìn)入生物反應(yīng)器。將反應(yīng)器中的硫化物轉(zhuǎn)化為單質(zhì)硫，同時堿液得到再生，可以重復(fù)使用。隨著嗜鹽脫硫菌的發(fā)現(xiàn)，分離式脫硫工藝得到了長足的發(fā)展。并且隨著科技的進(jìn)步，更加解決了一體式生物脫硫容易出現(xiàn)的硫填料易堵塞的問題。在沼氣提純CNG的工藝中、以及高濃度硫化氫的沼氣處理工藝中，分離式脫硫工藝占有優(yōu)勢。以上就是生物脫硫的介紹。
In the biogas scrubber, the gas containing hydrogen sulfide enters into the biological scrubber first, and then enters the biological scrubbing reactor. The sulfide in the reactor is converted into elemental sulfur, and the alkali liquor is regenerated, which can be reused. With the discovery of halophilic desulfurizing bacteria, the separation desulfurization process has been greatly developed. And with the progress of science and technology, it has solved the problem that sulfur filler is easy to block in integrated biological desulfurization. In the process of purification of CNG from biogas and the treatment process of high concentration hydrogen sulfide, the separation desulfurization process has the advantage. The above is the introduction of biological desulfurization.
