Environment-friendly biogas power generation biogas pretreatment method

Abstract

The invention provides an environment-friendly biogas pretreatment method for biogas power generation, and relates to the technical field of biogas pretreatment. The environment-friendly biogas pretreatment method for biogas power generation comprises the following step of: S1, wet desulphurization: conveying mixed gas generated by anaerobic fermentation in a biogas digester into a desulphurization tower for desulphurization treatment. According to the environment-friendly biogas power generation biogas pretreatment method, sulfide components in the biogas can be fully removed through wet desulphurization, so that excessive toxic and environment-polluting gas generated by the biogas during actual combustion is effectively reduced; meanwhile, the sulfide solution can be effectively prevented from severely corroding biogas conveying equipment; through dehydration treatment, the moisture content of the biogas can be effectively reduced; meanwhile, large solid particles in the biogas can be conveniently filtered; through filtration of solid impurities, the situation that in the actual conveying process of the biogas, the interior of conveying equipment is not prone to being blocked canbe avoided, and the biogas can be normally conveyed.

Description

technical field [0001] The invention relates to the technical field of biogas pretreatment, in particular to an environment-friendly biogas power generation biogas pretreatment method. Background technique [0002] Biogas combustion power generation is a biogas utilization technology that has emerged with the continuous development of large-scale biogas digester construction and comprehensive utilization of biogas. It uses the biogas generated by anaerobic fermentation treatment on the engine, and is equipped with a comprehensive power generation device to generate electricity. Biogas power generation has the characteristics of benefit creation, energy saving, safety and environmental protection. It is a widely distributed and cheap distributed energy source. However, in the prior art, direct and insufficient combustion of biogas is likely to produce toxic and polluting environment. Gas needs effective pretreatment before it can be used for combustion, and the pretreated bio...

[0002] Biogas combustion power generation is a biogas utilization technology that has emerged with the continuous development of large-scale biogas digester construction and comprehensive utilization of biogas. It uses the biogas generated by anaerobic fermentation treatment on the engine, and is equipped with a comprehensive power generation device to generate electricity. Biogas power generation has the characteristics of benefit creation, energy saving, safety and environmental protection. It is a widely distributed and cheap distributed energy source. However, in the prior art, direct and insufficient combustion of biogas is likely to produce toxic and polluting environment. Gas needs effective pretreatment before it can be used for combustion, and the pretreated biogas combustion still has the problem of insufficient combustion and the production of more toxic and environmentally polluting gases after combustion, so that it can be improved. The actual improvement effect of using biogas for power generation for the purpose of environmental pollution is not good
