NOVELTY - Ultra-efficient hydraulic biogas fermentation system comprises fermentation tank body, pressure rooms and gas plate; where the fermentation tank body is provided with a fermentation chamber, and the fermentation tank body are provided with left and right side walls, which are connected to the fermentation chamber feed inlet and outlet. The fermentation tank body sidewall is provided with support means, where the gas storage plate is placed in fermentation tank body and fixed to the supporting device.    USE - Used as ultra-efficient hydraulic biogas fermentation system.    DETAILED DESCRIPTION - Ultra-efficient hydraulic biogas fermentation system comprises fermentation tank body, pressure rooms and gas plate; where the fermentation tank body is provided with a fermentation chamber, and the fermentation tank body are provided with left and right side walls, which are connected to the fermentation chamber feed inlet and outlet. The fermentation tank body sidewall is provided with support means, where the gas storage plate is placed in fermentation tank body and fixed to the supporting device. The gas storage plate is provided with four rings, the top is sealed and the bottom is opened. The gas storage plate feed inlet side wall is provided with feed inlet air resistance plate and discharge port; where the width of gas discharge port blocking plate, gas storage plate and fermentation tank body is less than the gas chambers of fermentation tank body. A pressure plate is fixed between the feed inlet end side of the gas storage plate, and the discharge port is provided with drain spout. The system further includes a rod, which are cross bar or vertical rods, and at least one end of the bar is connected to the vertical stanchions, where the vertical top lever is provided with a hand lever located between the two vertical rods. The drain spout is provided with check valve for controlling the inflow of liquid inside the fermentation chamber.    DESCRIPTION OF DRAWING(S) - The drawing shows a schematic view of the ultra-efficient hydraulic biogas fermentation system.
