Abstract

The invention relates to an anaerobic digestion device and method for kitchen waste. The device comprises a box body, a motor, a rotating shaft, a crushing mechanism, a stirring mechanism and a discharging control mechanism; a partition plate is arranged on the middle portion of the box body to divide the internal space of the box body into a crushing chamber on the upper portion and a reaction chamber on the lower portion; the motor is arranged at the top of the box body, an output shaft of the motor extends into the box body and is connected with the rotating shaft, and the rotating shaft penetrates through the partition plate and then abuts against the bottom wall of the box body; a plurality of annular cutters are arranged on the outer side of the rotating shaft in the crushing chamber to form the crushing mechanism, and a plurality of stirring plates are arranged on the outer side of the rotating shaft in the reaction chamber to form the stirring mechanism. According to the invention, the crushing chamber and the reaction chamber are arranged in the same box body, and can be independent from each other and communicate with each other; the kitchen waste is firstly crushed and then the crushed kitchen waste enters the reaction chamber for a digestion reaction, and the crushing and reaction processes are continuously carried out, so that the treatment efficiency of the kitchen waste is greatly improved.

Description

technical field [0001] The invention relates to the technical field of garbage treatment, in particular to an anaerobic digestion device and method for kitchen garbage. Background technique [0002] Kitchen waste refers to the waste generated in the daily life of residents and activities such as food processing, catering services, and unit meals. Kitchen waste contains extremely high moisture and organic matter, and is easy to rot and produce stench; but after proper treatment and processing After that, it can be transformed into a new resource. [0003] Anaerobic digestion technology is a very suitable method for treating food waste. Anaerobic digestion technology refers to the decomposition of biodegradable organic matter into CH by facultative bacteria and anaerobic bacteria under anaerobic conditions. 4 , CO 2 、H 2 O and H 2 S's digestion technology can achieve the goals of circular economy development, environmental protection, reduction of greenhouse gas emissions ...
