Omnibearing dynamic anaerobic fermentation tank

Abstract

The invention discloses an omnibearing dynamic anaerobic fermentation tank, which comprises a fermentation tank body, a fermentation chamber, a gas storage chamber, a top return liquid storage tank, afeeding pipe, a communication pipe, an exhaust pipe, a discharging pipe and a manhole. The top of the fermentation tank body is provided with a top cover, a tank top is arranged inside the fermentation tank body, the upper part of the tank top is the top return liquid storage tank, the lower part of the tank top is the fermentation chamber, and the space between the liquid level of the fermentation chamber and the tank top is the gas storage chamber; the feeding pipe and the communication pipe are arranged on the inner wall of the fermentation tank body; the exhaust pipe is arranged on the top of the tank top to communicate with the gas storage chamber, and extends out from the top cover; and the discharge pipe is arranged on the outer side wall of the fermentation tank and communicates with the top return liquid storage tank, which solves the technical problems of sludge accumulation in the fermentation pipe, easy fracture and unstable biogas pressure due to unreasonable structure design of the fermentation tank, and low utilization rate in prior art.

Description

technical field [0001] The invention relates to the technical field of biomass energy development, and more specifically relates to a cylindrical omnidirectional dynamic anaerobic fermentation tank, which is suitable for biogas projects. Background technique [0002] The biogas project uses agricultural and agricultural product processing organic wastes as raw materials to produce biogas through anaerobic fermentation. Biogas can be used for household energy, industrial combustion, and power generation. It is of great significance for alleviating the dilemma of non-point source pollution and energy shortage in rural areas that are increasingly banned in my country. [0003] Hydraulic biogas digesters are the most widely used traditional biogas digesters in current biogas projects, including fermentation tanks, feed pipes, discharge pipes and sealing covers. The feed pipe and discharge pipe are usually on both sides of the fermentation tank body. The feed pipe can be used to...

Problems solved by technology

[0004] The purpose of the present invention is to overcome above-mentioned technical deficiencies, propose a kind of all-round dynamic anaerobic fermenter, solve the problem that in the prior art the sludge in the biogas tank is piled up on the bottom and both sides of the tank, the formation of invalid volume leads to low fermentation gas production; The pressure is unstable, the fluctuation is large and cannot be fully burned; the overall structure of the biogas digester is not good, and some parts are broken due to the load.
