The biogas biological desulfurization system comprises a desulfurization tower and nutrient circulation equipment. The desulfurization tower consists of a nutrient liquid chamber, a packing bed and a spray chamber. The packing bed is located in a spray chamber. The nutrient liquid chamber is provided with nutrient liquid inlet, dilution cooling water inlet, methane inlet and air inlet, and the spray chamber above the packing bed. The nutrient liquid circulating equipment comprises a circulating pump, a pipeline and a sprinkler head, which is located at the top of the sprinkler chamber; the biogas biological desulfurization system also includes a control device, an air supply controller and a fan are arranged on the pipeline of the air inlet, and a biogas oxygen is arranged on the pipeline of the biogas outlet. The air supply controller, the fan and the methane oxygen concentration detector are separately connected with the control equipment. The biogas biological desulfurization system described in the invention can achieve the biogas renewable utilization, safety and high intelligence.



目前污水、垃圾處理過(guò)程中，越來(lái)越多的工程項(xiàng)目選用厭氧處理工藝，沼氣作為一種衍生產(chǎn)物，漸漸被我們所熟知并利用。但從厭氧罐中出來(lái)的沼氣含有較高濃度的H2S及其它一些雜質(zhì)，如不對(duì)沼氣進(jìn)行脫硫、凈化處理，則會(huì)對(duì)沼氣運(yùn)送管道、存儲(chǔ)設(shè)備及后續(xù)運(yùn)用設(shè)備發(fā)生腐蝕，削減運(yùn)用年限并形成安全危險(xiǎn)。所以，通常是先通過(guò)脫硫凈化處理后再利用。
At present, in the process of sewage and garbage treatment, more and more projects choose anaerobic treatment technology. As a derivative, biogas is gradually known and used by us. But the biogas from the anaerobic tank contains high concentration of H2S and other impurities. If the biogas is not desulfurized and purified, it will corrode the biogas transportation pipeline, storage equipment and follow-up equipment, reduce the service life and form a safety hazard. Therefore, it is usually first treated by desulphurization and then reused.
常用的沼氣生物脫硫體系一般通過(guò)風(fēng)機(jī)供氧的方法，添加沼氣中的氧氣含量，并通過(guò)微生物的效果，將H2S轉(zhuǎn)化為硫單質(zhì)。沼氣脫硫體系的H2S通過(guò)處理后，會(huì)生成硫單質(zhì)，因?yàn)樘幚砗蟀l(fā)生的硫單質(zhì)量十分少，很難進(jìn)行再生利用，并且硫單質(zhì)在氣溫高時(shí)，會(huì)有提高現(xiàn)場(chǎng)，屬于風(fēng)險(xiǎn)廢 物，現(xiàn)場(chǎng)堆置或運(yùn)送都存在安全危險(xiǎn)；另外，沼氣生物脫硫體系的操控設(shè)備的智能化程度低，大部分由人進(jìn)行現(xiàn)場(chǎng)操作，對(duì)人身安全帶來(lái)很大的危險(xiǎn)。
The commonly used biogas biological desulfurization system is usually supplied by air blower, adding oxygen content in biogas, and converting H2S into sulfur by microbial effect. The H2S of biogas desulfurization system will produce sulfur element after treatment, because the quality of sulfur element after treatment is very small, it is difficult to recycle, and sulfur element will improve the site when the temperature is high, which belongs to risk waste, and there are safety risks in site stacking or transportation; in addition, the operation of biogas desulfurization system. The intelligent degree of control equipment is low, and most of them are operated by people on site, which brings great danger to personal safety.
