Abstract

The invention relates to a marsh gas generating device, belonging to the biomass energy utilizing and processing equipment, which is characterized in that: a liquid feed delivery pipe is arranged between the discharging opening of the down-flow anaerobic filer and the feeding opening of the up-flow anaerobic fermentation cylinder, the valve of the discharging opening, the liquid feed transferring pump and the valve of the feeding opening are arranged on the liquid feed delivery pipe, both ends of the circulating reflux pipe assembled with the valve at the feedback hole and the valve at the feeding opening of the reflux pipe are respectively connected with the feedback hole at the upper part of the down-flow anaerobic filter and the liquid feed delivery pipe, the upper side end, the lower side end and the bottom end of the discharging reflux pipe of the fermentation cylinder are communicated with the up-discharging opening on the up-flow anaerobic fermentation cylinder, the down-discharging opening and the liquid feed delivery pipe, and the discharging reflux pipe of the fermentation cylinder is provided with a valve. The marsh gas generating device has the advantages of simple structure, fast anaerobic fermentation, high gas generating speed, full fermentation of the liquid feed and convenient operation.

Description

technical field [0001] The invention belongs to biomass energy utilization and processing equipment, and mainly relates to a biogas generating device. Background technique [0002] In today's society, energy and environmental protection have become two prominent issues. In the case of decreasing non-renewable energy sources, people began to seek to maximize the use of biomass resources to supplement the energy shortage, and to eliminate the impact on the environment while utilizing biomass resources. pollution. Biogas anaerobic fermentation is a technology that uses agricultural wastes to be converted into energy and can be treated in a harmless manner. In order to improve the efficiency of biogas anaerobic fermentation devices, various methods and measures have been studied, but most of the methods are only applicable to Farmers and small processing units. With the development of large-scale production in the 21st century, the demand for large-scale industrial anaerobic f...
