隨著化石能源的枯竭,人們越來越重視環境保護,尋找清潔替代能源問題越來越迫切,解決能源問題是國家面對的現實,沼氣作為煤氣的替代品,已在各地推廣,成為生活能源的補充。沼氣脫硫越來越重要了。
With the depletion of fossil energy, people pay more and more attention to environmental protection, and it is more and more urgent to find clean alternative energy. To solve the energy problem is a reality faced by the country. Biogas, as a substitute for coal gas, has been popularized everywhere and has become a supplement to domestic energy. Biogas desulfurization is becoming more and more important.
沼氣和煤氣有什么區別?
What is the difference between biogas and gas?
煤氣是由煤或焦炭等固體原料經干餾或蒸發而成的氣體燃料。煤氣種類繁多,成分復雜。主要成分有一氧化碳、甲烷和氫氣。沼氣的主要成分是甲烷,由甲烷的50%~80%、二氧化碳的20%~40%、氫氣、硫化氫等氣體組成。
Coal gas is a kind of gaseous fuel made from coal or coke by dry distillation or evaporation. There are many kinds of gas with complex components. The main components are carbon monoxide, methane and hydrogen. The main component of biogas is methane, which is composed of 50%~80% of methane, 20%~40% of carbon dioxide, hydrogen, hydrogen sulfide and other gases.
沼氣是一種清潔的可再生能源,是一種衛生、廉價的氣體燃料,以沼氣為環節,加快農業生產結構調整,可提高農產品質量和效率,增加農民收入,使農民盡快擺脫貧困,沼氣產業實現農業生產和農民生活的循環發展,大大節約了農村能源。
Biogas is a kind of clean renewable energy and a kind of hygienic and cheap gas fuel. Taking biogas as as a link, accelerating the adjustment of agricultural production structure can improve the quality and efficiency of agricultural products, increase farmers' income, and enable farmers to get rid of poverty as soon as possible. The biogas industry realizes the circular development of agricultural production and farmers' life, which greatly saves rural energy.
大中型沼氣工程技術是一種農村能源工程技術,旨在開發利用農場糞便,獲取能源,控制環境污染,實現農業生態良性循環,主要通過厭氧發酵及相關處理降低糞便有機質含量,達到或接近排放標準,按厭氧發酵主體和配套工程技術設計技術要求獲得沼氣。
Large and medium-sized biogas engineering technology is a kind of rural energy engineering technology, which aims to develop and utilize farm manure, obtain energy, control environmental pollution, and realize a virtuous cycle of agricultural ecology. It mainly reduces the organic matter content of manure through anaerobic fermentation and related treatment, reaches or approaches the discharge standard, and obtains biogas according to the technical design requirements of the main body of anaerobic fermentation and supporting engineering technology.
沼氣中含有硫化氫氣體,燃燒前脫硫。在這個沼氣工程中,我們的偉大貢獻者生物脫硫塔做出了巨大的貢獻!脫硫塔工藝節省了氣體形式吸收塔中不可缺少的霧化噴嘴,大大降低了堵塞和結垢的可能性。旋流噴射暴氣管流速較高,處理大煙氣量時截面較小。
Methane contains hydrogen sulfide gas, which is desulfurized before combustion. In this biogas project, our great contributor biological desulfurization tower has made great contributions! The desulfurization tower process saves the indispensable atomizing nozzle in the gas absorption tower and greatly reduces the possibility of blockage and scaling. The velocity of cyclone jet vent pipe is high, and the cross section is small when dealing with large amount of flue gas.
