Biogas fermentation device

Abstract

The invention discloses a biogas fermentation device. The biogas fermentation device comprises a feeding pipe (1), a fermentation tank (14), a discharge chamber (8), a discharge pipe (10), a gas-guide pipe (3), a gas storage chamber (5), an exhaust pipe (7) and valves (9). The feeding pipe (1) is located at an upper end of the fermentation tank (14). The fermentation tank (14) is communicated with the discharge chamber (8). The discharge pipe (10) is arranged below the discharge chamber (8). The fermentation tank (14) is connected to the gas storage chamber (5) by the gas-guide pipe (3). The side wall of the gas storage chamber (5) is provided with the exhaust pipe (7). The gas-guide pipe (3) and the discharge pipe (10) are provided with the valves. The biogas fermentation device also comprises a distributing device (13), a stirring bar (12) and a heat exchanger (11). The distributing device (13) is located at the bottom of the fermentation tank (14) close to the feeding pipe (1). The stirring bar (12) is arranged in the center of the fermentation tank (14). The heat exchanger (11) is arranged in the fermentation tank (14). The biogas fermentation device has a simple structure, can be operated easily, is suitable for common popularization, can guarantee uniform material reaction and can effectively improve gas production efficiency.

Description

technical field [0001] The invention relates to a fermentation device, in particular to a biogas fermentation device. Background technique [0002] my country is a large agricultural country with a large rural population and a small amount of cultivated land, water and other resources per capita. This national condition determines that it is necessary to vigorously develop the efficient and multi-level utilization of agricultural resources; and biogas technology uses agricultural waste to Recovering energy and producing other agricultural supplies, this resource is recycled. Therefore, biogas technology is an effective way to efficiently utilize agricultural resources. However, most of the biogas fermentation devices currently used in rural areas have complex structures and high operating requirements, which are difficult to popularize and apply; moreover, it is difficult to ensure that the materials are evenly distributed in the fermentation device and cannot fully react, r...
