Description
Technical Field
The utility model belongs to the technical field of biogas production and manufacturing, and relates to a biogas tank.
Background
The large anaerobic biogas tanks constructed at present are all vertical cylindrical tanks, most designers consider that the diameter-height ratio of the anaerobic tanks is the optimal ratio of 1 to 1, and the height of the anaerobic tanks is designed to be more than 10 meters. However, experiments prove that the bearing pressure of the microorganisms in the anaerobic biogas tank cannot exceed 0.1MPa at most, and stirring is needed in a certain time. The height exceeds 0.1MPa, so that methane bacteria cannot rise to the air outlet, and the gas yield of the anaerobic methane tank is low. The tank body also causes material layering, especially the anaerobic methane tank using agricultural straw as raw material, layering is more serious, because the straw is more fibrous, and the crop straw stored in the open air is dried, and the crushed straw is directly added into the anaerobic methane tank without pretreatment, so that scabbing is caused on the upper part of the anaerobic methane tank, and therefore, the anaerobic methane tank is broken and explosion accidents occur frequently. The vertical anaerobic biogas tank of cylinder also has the restriction to material concentration, and material concentration can only be controlled between 4-8%, because the material floats when concentration is less than 4%, can appear not fully digested material outflow when discharging, and the biogas tank discharges difficultly when concentration is higher than 8%, and some materials can not fully mix. The anaerobic methane tank is easy to produce siphoning phenomenon. The check valve is a relatively clean fluid fitting, and is not preferable for closing the anaerobic biogas tank to prevent backflow because the material contains more fibers, especially the anaerobic biogas tank containing cow dung and straw, and the fibers in the material are easy to clamp in the middle of the check valve, so that the check valve is disabled, siphonage is generated or air enters the anaerobic biogas tank, and if the anaerobic biogas tank with lower feeding can completely flow out the materials in the tank. The anaerobic methane tank is made of metal materials, has poor heat preservation performance, can not meet the requirement of methane production in winter in cold areas, and is also a main reason for influencing the methane production.
