辽宁沈阳长白乡建了一个沼气发电站,它是利用酒厂的废酒糟液产沼气,然后用双燃料的发动机发电。经过多年运行,效果理想,使农村生产用电紧张的问题得到了缓解。这项工程经过了进一步设计,更加合理。它的发电工作原理是这样的: 首先将废酒糟稀释到一定浓度的浊液,用泵打入预热罐中预热到一定温度,然后再将这种糟液用泵打入发酵罐中,停留一段时间,在罐中进行中温发酵。中温发酵的温度由稻壳生物增温来保证,即用价格极便宜的稻壳来获得发酵罐所需要的中温能源。在发酵罐中产生沼气后,经贮气罐贮存供燃沼气的发动机
Changbai Township, Shenyang, Liaoning, built a biogas power plant, which uses the waste distiller’s distillery to produce biogas and then uses dual-fuel engines to generate electricity. After many years of operation, the effect is satisfactory and the problem of electricity shortage in rural areas has been alleviated. This project has been further designed, more reasonable. Its power generation principle is this: First, the waste distiller’s grains diluted to a certain concentration of turbid liquid, preheated with a pump into the preheated tank to a certain temperature, and then this bad liquid pump into the fermenter, Stay for a while and ferment in the tank at medium temperature. The temperature of the medium temperature fermentation is ensured by the biological warming of the rice husk, ie the husk energy required for the fermentor is obtained with the rice husk, which is extremely inexpensive. After generating biogas in the fermentor, it is stored in the storage tank for the engine that feeds the biogas
