太阳能沼气池

我国农村户用沼气池大都采用常温发酵.由于发酵温度随四季气温的变化而变化,所以冬春季节沼气池产气率不足的问题,是目前农村普及沼气技术亟待解决的问题之一.详述了太阳能沼气池的结构和工作原理,并通过经济分析,说明将太阳能热水供给技术与沼气池技术改造相结合,利用太阳能热水循环技术提高沼气池冬季产气率,降低沼气池一年四季供气量的波动范围,经济效益显著·太阳能沼气池实现了炊事用能,照明、冬季采暖等沼气供给和太阳能热水供应一体化,是解决农村能源紧缺问题,改善农民生活、生产条件,促进农业产业结构调整,保护农村生态环境,繁荣农村经济,增强农村可持续发展能力的重要举措.

Solar Energy Methane-Generating Pit

Most of methane-generating pit in the country ferments on ordinary temperature.Because the ferment temperature waves along with season temperature,biogas is not enough in spring and winter.And this is the biggest obstruction to popularize methane-generating pit.The structure and the principle of methane-generating pit were described.According to the economic analysis,the result shows that the combination of the solar energy hot water supply technology and methane-generating pit technological transformation ...
