沼气预处理系统描述厌氧发酵沼气是现代污水处理厂、酒精厂、养殖场正常生产的附属生成物。其主要成分为50~65%的甲烷与30~50%的二氧化碳,同时还含有水蒸气、硫化物、氮化物等上百种成分,其中甲烷是主要的温室效应污染物之一。沼气不仅会污染环境而且也会产生严重的安 全隐患,因此需要对厌氧沼气进行集中处理。
Biogas pretreatment system describes that anaerobic fermentation biogas is a subsidiary product of normal production in modern wastewater treatment plants, alcohol plants and farms. Its main components are 50-65% methane and 30-50% carbon dioxide, and it also contains hundreds of components such as water vapor, sulfide, nitrogen compounds, among which methane is one of the main greenhouse effect pollutants. Biogas will not only pollute the environment, but also cause serious security risks, so it is necessary to treat anaerobic biogas centrally.
而以上的工厂一般都是耗电大户,将正常生产产生的沼气集中收集用于发电,不仅能提高资源的利用率,同时也可以减少对市电的依赖。因此对于产气量较大的污水处理厂、酒精厂、养殖场,可以采用沼气热电联产工艺。沼气预处理系统是沼气发电工程中的一个重要设备,该系统不仅用于实现对沼气的脱水、脱硫、稳压、去除杂质、安 全保护等功能,同时还是沼气厌氧反应罐与发电机组之间的燃气输送桥梁。

The above factories are generally large consumers of electricity. The centralized collection of biogas from normal production for power generation can not only improve the utilization rate of resources, but also reduce the dependence on municipal power. Therefore, biogas cogeneration process can be used for wastewater treatment plants, alcohol plants and farms with large gas production. Biogas pretreatment system is an important equipment in biogas power generation project. The system is not only used to realize the functions of dehydration, desulfurization, pressure stabilization, impurity removal and safety protection of biogas, but also a gas transmission bridge between biogas anaerobic reaction tank and generator set.
由于沼气属于易燃易爆的气体,安 全应该作为设计主要原则。同时还要兼顾系统的可靠性、经济性。
As biogas is flammable and explosive gas, safety should be the main principle of design. At the same time, the reliability and economy of the system should be considered.
