A two-phase anaerobic fermentation self-stirring reaction device

Abstract

The invention discloses a two-phase anaerobic fermentation self-stirring reaction device, and belongs to biogas fermentation equipment; a subsidiary fermentation chamber and a main fermentation chamber of which the volume ratio is 1: (10-15) are arranged in a water jacket type fermentation tank, a feed pipe assembly with a feed valve is assembled in the main fermentation chamber, a stirring impeller is mounted at the lower port of the feed pipe assembly, biogas slurry-biogas residue discharge conveying pipes are assembled on the subsidiary fermentation chamber and in the main fermentation chamber, a cylindrical baffle plate is configured in the subsidiary fermentation chamber, a pneumatic pipeline assembled with a barometer and an auto-control solenoid valve communicates the main fermentation chamber with the subsidiary fermentation chamber, and an overflow valve is mounted on the water jacket type fermentation tank and communicated with the subsidiary fermentation chamber; according to the device disclosed by the invention, the two-phase anaerobic fermentation is configured on the same water jacket type fermentation tank, and self-stirring of a fermentation material liquid is realized without outer transmission power consumption, thus the two-phase anaerobic fermentation self-stirring reaction device has the characteristics of reasonable and compact structure, high degree of automation, good energy-saving effect and simple technical process.

Description

technical field [0001] The invention belongs to biogas fermentation equipment, and mainly relates to a two-phase anaerobic fermentation reaction device which can stir the fermentation material liquid by itself during the fermentation process of organic waste. Background technique [0002] At present, the two-phase anaerobic fermentation device is to separate the acid-producing phase and the methane-producing phase, and carry out anaerobic fermentation in two reactors respectively. The two reactors need to be heated and kept warm, which results in high energy consumption and large heat loss; In addition, the stirring process of the feed liquid in the fermentation operation mostly uses external power mechanical stirring, which increases energy consumption and easily destroys the stability of the microbial community. The popularization and application of two-phase anaerobic fermentation technology. Contents of the invention [0003] The purpose of the present invention is to...
