沼气发电工艺流程：沼气池-沼气-脱水脱硫-气水分离-过滤-压缩-气水分离-冷却-发电机组-配电室-用户-循环冷却。根据沼气发电机组的工作特点，在组建沼气发电机组系统时，要着重考虑以下几个方面：

Biogas power generation process flow: biogas digester - biogas - dehydration and desulfurization - gas water separation - filtration - compression - gas water separation - cooling - generator set - power distribution room - user - circulating cooling. According to the working characteristics of the biogas generator set, the following aspects should be considered when establishing the biogas generator set system:

1、沼气脱硫及稳压、防爆装置：沼气中含有少量的H2S，该气体对发动机有强烈的腐蚀作用，因此供发动机使用的沼气要先经过脱硫装置。沼气作为燃气，其流量调节是基于压力差，为了使调节准确，应确保进入发动机时的压力稳定，故需要在沼气进气管路上安装稳压装置。另外，为了防止进气管回火引起沼气管路发生爆炸，应在沼气供应管路上安置防回火与防爆装置。

1. Methane desulfurization, pressure stabilizing and explosion-proof devices: the biogas contains a small amount of H2S, which has a strong corrosive effect on the engine. Therefore, the biogas used for the engine must first pass through the desulfurization device. As the fuel gas, the flow regulation of biogas is based on the pressure difference. In order to make the regulation accurate, the pressure stability when entering the engine should be ensured, so it is necessary to install a pressure stabilizing device on the biogas inlet pipeline. In addition, in order to prevent explosion of biogas pipeline caused by backfire of intake pipe, anti backfire and explosion-proof devices shall be installed on biogas supply pipeline.

2、进气系统：在进气总管上，需加装一套沼气-空气混合器，以调节空燃比和混合器进气量，混合器应调节灵敏。

2. Intake system: A set of biogas air mixer shall be installed on the intake manifold to adjust the air fuel ratio and the intake volume of the mixer. The mixer shall be sensitive.

3、发动机：沼气的燃烧速度很慢，若发动机内的燃烧过程组织不力，会影响发动机运行寿命，所以对沼气发动机有较高的要求。

3. Engine: The combustion speed of biogas is very slow. If the combustion process in the engine is poorly organized, it will affect the operating life of the engine. Therefore, there are high requirements for biogas engines.

4、调速系统：沼气发动机的运行场合是和发电机一起以用电设备为负荷进行运转，用电设备的装载、卸载会使沼气发动机负荷产生波动，为了确保发电机组正常发电，沼气发电机组的调速系统必不可少。

4. Speed governing system: the biogas engine operates with the generator under the load of electrical equipment. The loading and unloading of electrical equipment will cause fluctuations in the load of the biogas engine. In order to ensure the normal power generation of the generator set, the speed governing system of the biogas generator set is indispensable.
