Problems solved by technology

[0004] After the amount of biogas produced by the biogas digester exceeds the amount used, the excess biogas stored in the digester or discharged into the air will cause some pollution or safety problems, and the amount of biogas generated by a single digester cannot meet long-distance transportation or biogas generators The needs of operation, thus causing the dilemma of biogas use
[0005] However, the inventors have found that when multiple biogas digesters are concentrated and distributed in a close range, each biogas digester may face a similar predicament, and directly connecting the biogas of multiple biogas digesters to one pipeline will cause the Uneven air pressure causes biogas to flow back to a small amount of biogas digesters with low biogas pressure, which brings safety hazards

Abstract

The invention relates to the technical field of biogas production devices, and especially relates to biogas digester pressure-controlling and flow-collecting equipment having anti-backflow effects. The structure of the device is that a closed cavity having multiple gas-guiding tubes are arranged; liquid is needed to be arranged in the cavity during using; the gas-guiding tubes include gas inlet tubes and gas outlet tubes; one ends of the gas inlet tubes are located below the liquid level in the cavity, and the other ends of the gas inlet tubes are used for introducing gas in a biogas digester;and the gas outlet tubes are used for exporting the gas at the upper part of the liquid level in the cavity. Through the utilization of the equivalent pressure of liquid columns in the gas inlet tubes, the pressure of biogas in the biogas digester can be controlled in a certain range, so that the normal using of the biogas can be guaranteed, the biogas can be prevented from accumulating in the biogas digester to cause high pressure risk, and the purpose of the safe combination of multiple biogas digesters can be realized; and in addition, the device can make each biogas digester not directlycommunicate with each other, so that the biogas in the biogas digester whose gas pressure is relatively high can be avoided from flowing in the biogas digester whose gas pressure is relatively low, namely, the risks that the biogas returns to the biogas digesters can be prevented.

Description

technical field [0001] The invention relates to the technical field of biogas production devices, in particular to a pressure-controlling and flow-collecting device for a biogas tank with the function of preventing backflow. Background technique [0002] The information disclosed in the Background of the Invention is only intended to increase the understanding of the general background of the invention, and is not necessarily to be taken as an acknowledgment or any form of suggestion that the information constitutes the prior art that is already known to those skilled in the art. [0003] With the improvement of environmental protection requirements and the development of biogas digester technology, many farms, communities, and households have built biogas digesters. Biogas residues and biogas slurry can be used as excellent fertilizers for agricultural production. Biogas can be used for lighting, cooking, Heating, power generation and other purposes. At the same time, affe...
