印度沼气池与中国沼气池是现在国际上并驾齐驱的两类不同池型,值得分析,以取其长,补已之短。一、印度的池型和工艺特点1.池型结构特点由图可见①浮罩式气箱;②浮罩上带有简易拌搅器;③沼气池中部装有一道隔墙;④进、出料管靠近池底;⑤池体高跨比较大。2.工艺特点①进料主要为流加,出料为溢流法;②采用单一原料——牛粪,原料经预发酵处理后滤渣流加;③沉渣和浮壳较少;④压力恒定,气压为7～15厘米水柱高;⑤较长期不清池,不“大出料”。
Biogas digesters in India and China digesters are now two types of different types of tanks that are currently on an international scale. It is worth analyzing to take a long and short term. First, the Indian pool and the characteristics of the process 1 pool-type structure can be seen from the figure ① floating hood gas box; ② floating hood with a simple mixer; ③ central digester with a wall; ④ into, out Tube close to the bottom of the pool; ⑤ pool body span is relatively large. 2. Process Features ① The main feed for the flow, the discharge method for the overflow; ② The use of a single raw material - cow dung, the feed after the pre-fermentation residue flow; ③ less sediment and floating shell; ④ constant pressure, Pressure is 7 to 15 cm water column high; ⑤ more long-term unclean pool, not “big out.”
