沼气工程并不是没有大范围推广,而是由于工业化程度过低所以没有在工业化。沼气提纯也是沼气工程的一个重要步骤!
The biogas project is not not not popularized on a large scale, but is not industrialized in China because of the low degree of industrialization. Biogas purification is also an important step in biogas engineering.
以德国、瑞典为例的沼气发达国家的沼气工程产量规模已经可以用于大规模区域供暖、发电、车用燃气,其中的主要原因就是工业化程度差异。
Taking Germany and Sweden as examples, the production scale of biogas projects in developed countries can be used for large-scale regional heating, power generation and automotive gas. The main reason is the difference of industrialization degree.
我国沼气以户用型沼气池为主,即便是沼气工程,发酵罐规模也相对而言较小。特点是无加热或加热设备落后(盘管)、无搅拌或使用简单的机械搅拌、无预处理等,这些都是导致我国沼气反应器产量低、反应速度慢甚至被弃置的原因。
Domestic biogas digesters are the main type of biogas in China. Even in biogas engineering, the scale of fermentation tanks is relatively small. It is characterized by no heating or backward heating equipment (coil), no stirring or simple mechanical stirring, no pretreatment and so on. These are the reasons for low production, slow reaction speed and even abandonment of biogas reactors in China.
生物反应对温度非常敏感,这也是沼气池夏季产气多、冬季产气少的原因,因此沼气反应器的增温保温是维持稳定沼气产出的重要因素之一。
Biological reaction is very sensitive to temperature, which is also the reason why methane digester produces more gas in summer and less gas in winter. Therefore, the heat preservation of biogas reactor is one of the important factors to maintain stable methane production.
我国比较成功的大规模沼气工程也很多,例如北京德清源、内蒙古蒙牛奥亚等等。
There are many successful large-scale biogas projects in China, such as Deqingyuan in Beijing, Mengniu Aoya in Inner Mongolia and so on.
