[0002] Biogas is a product produced by the fermentation of organic matter under certain temperature, humidity and anaerobic conditions and the decomposition of special microorganisms. Biogas is a convenient and clean gas fuel that can be burned directly or used as fuel for internal combustion engines. At the same time, biogas is a biomass conversion energy and a renewable energy source.

[0003] In the existing biogas power generation process, biogas needs to be transported, desulfurized and separated from gas and water. However, Roots blowers are generally used to transport biogas during biogas transportation. In the desulfurization process, the efficiency of desulfurization is reduced due to insufficient transportation pressure. In addition, the quality of biogas after gas-water separation after desulfurization is generally poor, which affects the quality of biogas. For this reason, we propose a biogas transportation device for biogas power generation. Utility Model Content
