Description

Technical Field

[0002] Based on the different types of aerobic demand, common fermenters can be divided into ventilated fermenters and anaerobic fermenters. Anaerobic fermenters cannot contain dissolved oxygen and mostly rely on the density difference of the culture medium to achieve uniform circulation of the liquid. Anaerobic fermenters often need to be equipped with a water distribution device inside.

[0003] Currently, existing anaerobic digester water distribution devices, such as Chinese Patent Publication No. CN213388605U, disclose a water distribution device for an anaerobic digester, including a fixed pipe, a rotating main pipe, a connecting pipe, and a rotating branch pipe. The fixed pipe is fixed to the top of the digester and its bottom end is sealed. The rotating main pipe is sleeved on the end of the fixed pipe that extends into the digester and can rotate around the fixed pipe under the drive of a power component. At least one set of connecting pipes is provided, with one end connected to the fixed pipe and the other end sealed and fixed inside an annular slide bar. The annular slide bar is rotatably connected to an annular groove inside the digester. Inside; at least one set of rotating rings is also sleeved outside the connecting pipe, and a liquid storage chamber that can communicate with the connecting pipe is formed between the rotating rings and the connecting pipe. At least one set of rotating branch pipes is also connected outside the rotating rings. One end of the rotating branch pipe is sealed and the other end is connected to the liquid storage chamber. Multiple sets of liquid outlets are also provided on one side of the rotating branch pipe. The liquid can enter the tank body by passing through the fixed pipe, the rotating main pipe, the rotating ring of the connecting pipe, and the rotating branch pipe in sequence. However, the water distribution device in the anaerobic fermenter is mostly fixed to improve its stability. The movement mode of the above-mentioned device is not stable, and the water distribution volume and uniformity are poor.

[0004] Improving the uniformity and stability of water distribution, enhancing water distribution efficiency, and simplifying installation and disassembly for easy maintenance by repair personnel has become a technical challenge that needs to be addressed.
