厭氧反應(yīng)會發(fā)生沼氣，該沼氣通常包含一定量的硫化氫。不同的工業(yè)廢水中沼氣中硫化氫的含量也不同。假如硫化氫含量太高，則在進(jìn)入鍋爐之前必須去除沼氣中的硫化氫，以免腐蝕管道和鍋爐。
沼氣脫硫的這些特性，你足夠清楚嗎？
Anaerobic reaction will produce biogas, which usually contains a certain amount of hydrogen sulfide. The content of hydrogen sulfide in biogas is different in different industrial wastewater. If the content of hydrogen sulfide is too high, the hydrogen sulfide in the biogas must be removed before entering the boiler to avoid corrosion of the pipeline and boiler. Do you know enough about these characteristics of biogas desulfurization?
這是一種使用生物菌株從沼氣中去除高腐蝕性，劇毒的硫化氫氣體的方法。該工藝具有自動化程度高，工藝簡略，運行成本低的優(yōu)點。厭氧發(fā)酵發(fā)生的沼氣進(jìn)入洗滌塔，并與堿性循環(huán)噴霧器進(jìn)行吸收反應(yīng)，從沼氣中去除硫化氫。吸收富液的硫化氫返回到生物反應(yīng)器中，經(jīng)過生物轉(zhuǎn)化將硫化氫轉(zhuǎn)化為固體元素硫，并將溶液再生為堿性吸收液，可用于洗滌沼氣，然后完成了吸收劑的再循環(huán)和再循環(huán)。硫固體的分離經(jīng)過硫沉淀器完成。
Biogas desulfurization is a method to remove highly corrosive and highly toxic hydrogen sulfide gas from biogas by using biological strains. The process has the advantages of high automation, simple process and low operation cost. The biogas generated by anaerobic fermentation enters the washing tower and absorbs reaction with the basic circulation sprayer to remove hydrogen sulfide from the biogas. The hydrogen sulfide absorbed from the rich solution is returned to the bioreactor. After biotransformation, the hydrogen sulfide is converted into solid element sulfur, and the solution is regenerated into alkaline absorption solution, which can be used to wash the biogas, and then the recycling and recycling of the absorbent are completed. The separation of sulfur solids is completed by sulfur precipitator.
沼氣脫硫?qū)⑷鯄A性條件下硫化氫的物理化學(xué)吸收與堿性溶液在空氣中的生物再生結(jié)合在一起。不含硫化氫的沼氣從洗滌塔頂部逸出，含硫化氫的溶液流入生物反應(yīng)器，在限制氧氣供給的條件下，其被氧化成元素硫和堿。少數(shù)廢水和副產(chǎn)品硫都不含硫化物，可以直接排放。
Biogas desulfurization combines physicochemical absorption of hydrogen sulfide under weak alkaline conditions with biological regeneration of alkaline solution in air. The biogas without hydrogen sulfide escapes from the top of the scrubber, and the solution containing hydrogen sulfide flows into the bioreactor. Under the condition of limiting oxygen supply, it is oxidized to elemental sulfur and alkali. A few waste water and by-product sulfur are free of sulfide and can be discharged directly.
