Abstract

The invention provides a biogas power generation method. Biogas is purified before power generation, so that the quality of the biogas meets the requirements of power generation parameters so as to achieve higher power generation efficiency. Biogas first passes through a pretreatment pipeline filled with silica gel at a flow rate of 12-15m / s, then successively passes through a first pipeline filled with a first treatment agent, a second pipeline filled with a second treatment agent and a third pipeline filled with a third treatment agent, and finally passes through an end pipeline filled withsilica gel, and the purified biogas is led out. The pretreatment pipeline is used for drying and removing most of the moisture in biogas. The first pipeline is used for adsorbing and removing most carbon dioxide and a small part of hydrogen sulfide. The second pipeline is used for adsorbing and removing hydrogen sulfide and a small part of carbon dioxide. The third pipeline is used for adsorbing and removing residual carbon dioxide and hydrogen sulfide. The residual moisture is removed by adsorption through the end pipeline, and the purified biogas has low contents of water, hydrogen sulfide,carbon dioxide, etc, and has high power generation efficiency.

Description

technical field [0001] The invention relates to the technical field of clean energy, in particular to a biogas power generation method. Background technique [0002] Biogas technology occupies a very important position in my country's sustainable development strategy. Biogas is a combustible gas produced by microbial fermentation of organic matter in an anaerobic environment under certain conditions of temperature, humidity and pH. Biogas is a clean energy that makes full use of agricultural or industrial production waste. It can be used for daily cooking, lighting, biogas power generation, and biogas thermal energy processing. [0003] Among them, biogas 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 is a new technology for comprehensive energy utilization that integrates environmental protection and energy saving. It is a widely dis...
