Embodiment 1

[0048] This embodiment provides an integrated vertical two-phase anaerobic reaction device, the structure of which is shown in figure 1 As shown, the reaction tank 1 is included, and a central inner cylinder 2 is arranged in the middle position of the reaction tank 1, so that a hydrolysis and acidification reaction zone located in the central inner cylinder 2 is formed in the reaction tank 1, and the inner wall of the reaction tank 1 is formed. With the methane-producing zone between the outer walls of the central inner cylinder 2, the hydrolysis and acidification reaction zone is communicated with the bottom of the methane-producing zone, and the top of the reaction tank body 1 is also sealed with a reaction tank top cover 3. The top cover 3 is also provided with a biogas outlet 5 . The ratio of the inner diameter of the central inner cylinder 2 to the inner diameter of the reaction tank body 1 is greater than 1:2. The height of the top of the central inner cylinder 2 is hig...

Abstract

The invention relates to an integrated vertical two-phase anaerobic reaction device and process, the device comprises a reaction tank body, a central inner cylinder is arranged at the middle position of the reaction tank body, so that a hydrolytic acidification reaction zone located in the central inner cylinder and a methane production zone located between the inner wall of the reaction tank body and the outer wall of the central inner cylinder are formed in the reaction tank body; the hydrolytic acidification reaction area is communicated with the bottom of the methane production area, the top of the reaction tank body is sealed by a reaction tank top cover, and a methane outlet is formed in the reaction tank top cover. According to the invention, an acidogenic phase reactor and a methanogenic phase reactor are integrated in one vertical reactor to realize the two-phase process of hydrolysis and anaerobic methane production, and the technical problems of low methanogenic efficiency and low system integration efficiency of a two-phase anaerobic reactor in the prior art are solved.

Description

technical field [0001] The invention belongs to the technical field of anaerobic reactors, and relates to an integrated vertical two-phase anaerobic reaction device and a process. Background technique [0002] In recent years, the pollution of organic solid wastes such as straw, organic waste, agricultural and sideline products has gradually attracted people's attention, and conventional treatment methods such as landfill, incineration, and composting have certain problems. In fact, the above garbage components are mainly organic components and have high biodegradability. Anaerobic digestion technology is used to recover biogas as biomass energy while processing organic waste, and the fermentation products can be processed after treatment. It has strong feasibility as fertilizer. [0003] The Chinese Patent Publication No. CN112410188A discloses a biogas production device by two-phase anaerobic fermentation of straw. The method divides the anaerobic production of biogas int...
