科学合理地开发利用沼气,不仅能创造可观的经济效益,还能保护生态环境,促进可再生能源的开发利用,因此沼气发电机组就发挥着很大的作用,下面来讲讲其内部系统的一些事。
The scientific and rational development and utilization of biogas can not only create considerable economic benefits, but also protect the ecological environment and promote the development and utilization of renewable energy. Therefore, the biogas generator unit plays a great role. Let's talk about its internal system.
1、沼气脱硫及稳压、防爆装置:供发动机使用的沼气要先经过脱硫装置,以减少硫化氢对发动机的腐蚀。沼气进气管路上安装稳压装置,以便于对流量进行调节,达到佳的空燃比。另外,为防止进气管回火,应在沼气总管上安置防回火与防爆装置。
1. Methane desulfurization, pressure stabilizing and explosion-proof devices: the biogas used for the engine shall first pass through the desulfurization device to reduce the corrosion of hydrogen sulfide on the engine. A pressure stabilizing device is installed on the biogas inlet pipe to facilitate the flow adjustment and achieve a good air fuel ratio. In addition, anti backfire and explosion-proof devices shall be installed on the biogas main pipe to prevent backfire of the intake pipe.
2、进气调节系统:在进气总管上,需设置一套精确、灵敏的燃气混合器,以调节空气和沼气的混合比例。
2. Intake air conditioning system: A set of accurate and sensitive gas mixer shall be set on the intake manifold to adjust the mixing ratio of air and biogas.
3、发动机点火系统:沼气的燃烧速度慢,对于原来使用汽油、柴油已及天然气的发动机的点火系统要进行一定程度的改造,以提高燃烧效率,减少后燃烧现象,延长运行寿命。
3. Engine ignition system: the combustion speed of biogas is slow, and the ignition system of engines that used gasoline, diesel and natural gas should be modified to a certain extent to improve the combustion efficiency, reduce the post combustion phenomenon and extend the operating life.

4、调速系统:若沼气发电机组独立运行,即以用电设备为负荷进行运转,用电设备的并入和卸载都会使发电机的负荷产生波动。为了确保发电机组正常运行,沼气发动机上的调速系统必不可少。
4. Speed governing system: if the biogas generator unit operates independently, that is, it operates with the electrical equipment as the load, the incorporation and unloading of electrical equipment will cause the load of the generator to fluctuate. In order to ensure the normal operation of the generator set, the speed regulating system on the biogas engine is essential.
5、预热利用系统:采用预热利用装置,对发动机冷却水和排气中的热量进行利用,提高沼气的能源利用效率。
5. Preheating utilization system: Preheating utilization device is used to utilize the heat in engine cooling water and exhaust gas to improve the energy utilization efficiency of biogas.
6、并网控制系统:主要包括发电机调压电路,自动准同期并列控制电路,手动并列和解列控制电路,测量电路,燃气发动机及辅助设备控制电路等。
6. Grid connected control system: mainly including generator voltage regulating circuit, automatic quasi synchronous parallel control circuit, manual parallel and de parallel control circuit, measuring circuit, gas engine and auxiliary equipment control circuit, etc.
沼气发电系统对电能的经济使用方式是先满足建设单位自身的用点需求,然后再将多余的电力并入公共电网;产生的热能也是先满足发酵池的所需,然后再考虑住所、农场的取暖或输送至公用供热网。
The economic use of electricity by biogas power generation system is to first meet the needs of the construction unit's own point of use, and then connect the surplus electricity to the public grid; The generated heat energy also meets the needs of the fermentation tank first, and then considers the heating of the residence and farm or the transmission to the public heating network.
