Understanding how biogas is produced is helpful for better use of biogas generating units. Specific content jichai introduction!

沼氣是一種可燃?xì)怏w，由于這種氣體先是在沼澤中發(fā)現(xiàn)的，所以稱為沼氣。

Biogas is a kind of combustible gas, because this gas was first found in the swamp, so it is called biogas.

那么 ，沼氣是怎樣產(chǎn)生的？

So, how is biogas produced?

沼氣是有機(jī)物在隔絕空氣和某溫度、濕度、酸堿度等的條件下，經(jīng)過(guò)沼氣細(xì)菌的作用產(chǎn)生的一種可燃?xì)怏w。

Biogas is a kind of combustible gas produced by biogas bacteria under the condition of isolation of air, temperature, humidity, pH, etc.

沼氣含有哪些成分？

What are the components of biogas?

沼氣是一種混合氣體，主要成分是甲烷、其余為二氧化碳、氧氣、氮?dú)夂土蚧瘹?。其中甲烷含量約為55%-70%，二氧化碳含量約為30%-45%。

Biogas is a mixture of methane, carbon dioxide, oxygen, nitrogen and hydrogen sulfide. The methane content is about 55% - 70%, and the carbon dioxide content is about 30% - 45%.

沼氣的物理、化學(xué)性質(zhì)怎樣？

What are the physical and chemical properties of biogas?

沼氣的主要成分是甲烷。甲烷是無(wú)色、無(wú)臭的氣體，分子式CH4，分子量為16.04，在一個(gè)大氣壓下甲烷對(duì)空氣的相對(duì)密度為05548，沼氣約為0.94。

Methane is the main component of biogas. Methane is colorless, odorless gas, molecular formula CH4, molecular weight is 16.04, in an atmospheric pressure, the relative density of methane to air is 05548, biogas is about 0.94.

沼氣發(fā)動(dòng)機(jī)廢氣的余熱利用方法？

Waste heat utilization method of biogas engine exhaust gas?

1）發(fā)動(dòng)機(jī)廢氣的余熱→通過(guò)廢熱鍋爐產(chǎn)生蒸汽→加熱消化器

1) Waste heat of engine exhaust gas → steam generated by waste heat boiler → heating digester

2）發(fā)動(dòng)機(jī)廢氣的余熱→通過(guò)換熱器產(chǎn)生熱水→加熱消化器

2) Waste heat of engine exhaust gas → hot water generated by heat exchanger → digester heated

3）發(fā)動(dòng)機(jī)廢氣的余熱→通過(guò)廢氣吸收式冷熱水熱水器→用于空調(diào)系統(tǒng)

3) Waste heat of engine exhaust gas → through exhaust gas absorption cold water heater → for air conditioning system

沼氣燃燒發(fā)電是隨著大型沼氣池建設(shè)和沼氣綜合利用發(fā)展而出現(xiàn)的一項(xiàng)沼氣利用技術(shù)，它將厭氧發(fā)酵處理產(chǎn)生的沼氣用于發(fā)動(dòng)機(jī)上，并裝有綜合發(fā)電裝置，以產(chǎn)生電能和熱能。當(dāng)然除了沼氣發(fā)電機(jī)組，還有柴油發(fā)電機(jī)組、汽油發(fā)電機(jī)組、秸稈氣發(fā)電機(jī)組等類型。用戶在選擇發(fā)電機(jī)組的時(shí)候要根據(jù)工作需要選擇適合的機(jī)組！

Biogas combustion power generation is a biogas utilization technology with the development of large-scale biogas digester construction and comprehensive utilization of biogas. It uses biogas produced by anaerobic fermentation for engine, and is equipped with comprehensive power generation device to generate electric energy and heat energy. Of course, in addition to biogas generator set, there are diesel generator set, gasoline generator set, straw gas generator set and other types. When users choose the generator set, they should choose the right one according to their work needs!
