Biogas cellar that can be used for anaerobic fermentation of two pH levels

Abstract

The invention discloses a methane cellar suitable for anaerobic fermentation under two pH values, comprising a cellar body, a cellar cover, a material access chamber, a cloth bag fixture, a cloth bag and a winding device. The cellar body has a first material chamber. The cloth bag has a second material chamber. The single cellar may serve as two systems by isolating the second material chamber with the first material chamber; the single cellar may internally allow anaerobic fermentation under two pH values at the same time, thus efficient methane production is achieved; the pH values of the second and first material chambers may be adjusted over the material access chamber, thus the first material chamber is kept under fermentation conditions suitable for efficient methane production during discharging; the methane cellar is simple in structure and low manufacturing cost; the cellar cover is disposed at the top of the cellar body in a separable or tight closing manner, after the cellar cover is siphoned for drainage and opened, an operator may enter the cellar body to perform operations such as mounting, cleaning, sterilizing, cloth bag changing and maintaining, and operating is simple and convenient.

Description

technical field [0001] The invention relates to the technical field of equipment for producing biogas, in particular to a simple biogas cellar which can be used for anaerobic fermentation of two kinds of acidity and alkalinity in an airtight condition by using a hydraulic rubber ring in close contact with the inner wall of the cellar. Background technique [0002] Making biogas from raw materials such as garbage and manure is not only a way out for countries to utilize sustainable energy, but also an important measure to develop sustainable agriculture and protect the ecological environment. The efficiency, economic benefits and popularity of biogas production are all limited by the construction cost of biogas cellars (pools) and troublesome operation and maintenance. At present, biogas cellars are commonly used in developing countries, and the most common one is the Chinese-style fixed dome biogas cellar, followed by the Indian-style floating cover biogas cellar. Both of t...
