摘要
沼气利用作为一项实用技术对合理利用农村能源,改善农村生态环境,提高农民生活质量具有重要作用,但在北方地区受气候影响冬季无法正常使用。本项目进行了北方冬季沼气正常使用技术研究,研究结果表明,采用电热膜加保温层的技术与利用太阳能热水器技术为沼气池保温、增温能有效解决北方冬季沼气池使用难得问题。
Biogas technology is contributing to solving rural energy problems, but it is difficult to apply in winter, specially in northern part of China because of low temperature. Digester heating and insulation are studied and economic feasibilities are calculated in this paper. The result showed that the methods of electrothermal film combined with insulating layer and solar water heater technology are effective to solve the low temperature problem for biogas digester in northern part of China.
