Net cage plug flow type fermentation device and operational method thereof

Abstract

The invention relates to a net cage plug flow type fermentation device and an operational method thereof. The net cage plug flow type fermentation device is characterized by comprising a gallery, wherein feed liquid is filled into the gallery; a net cage delivering device used for delivering the net cage into and out of the gallery is arranged on the gallery; a gas guide pipe and a gas return pipe are arranged at the inner upper part of the gallery; the output end of the gas guide pipe is provided with two pipelines of which one is connected with a biogas collecting device and the other one is connected with a biogas compression pump; the output end of the biogas compression pump is connected with the input end of the gas return pipe; a plurality of jet exhausts are arranged at intervals on the gas return pipe; one net cage is correspondingly positioned below each jet exhaust; and a heating pipe is also arranged at the inner upper part or the inner lower part of the gallery and connected with hot circulating water. The net cage plug flow type fermentation device is convenient to operate, has low energy consumption and high gas yield, can effectively avoid incrustation and blockage of the gallery, and provides a favorable anaerobic environment, thus being widely used in the fermentation process of excrement and straw.

Description

technical field [0001] The invention relates to a fermenting device and an operating method thereof, in particular to a net cage plug-flow fermenting device and an operating method thereof. Background technique [0002] With the advancement and development of the new rural construction, in order to build a civilized, hygienic, beautified and purified livable environment, villages and towns must implement new measures of separation of people and animals, and waste classification management. The main source of energy is biomass energy. In this way, the fermentation materials of biogas projects for centralized gas supply in rural areas will be mainly crop straw, kitchen waste and domestic organic waste and human excrement. The advantages of this process technology route are that it not only treats manure, straw, and organic waste to make them clean energy and green organic compound fertilizers, but also improves the environmental sanitation in rural areas. The hematopoietic fu...
