The paper introduces the technologies of transformation from diesel engine to biogas-diesel double fuel engine and the design keys of the main component,and brings forward the technical measures of biogas purification and pipage which are more suitable for the engine,as well.

介绍了将畜禽场柴油发电机转换为沼气-柴油双燃料发电机的基本方法和关键部件的设计要点，提出了更符合内燃机燃烧特性的沼气净化与输配技术措施，使得沼气-柴油双燃料发电机在保持原柴油发电机使用特性的同时，大幅降低柴油的消耗量，取得良好的实际效果。

Accordance with volume of biogas actually using requirement so that actualize supporting facilities, it can keep the pressure contant of biogas using for long time, the floating cover upside of body be pressurized, when the floating cover biogas digester fermenting to produce biogas will drive the soft PVC floating cover rising up with biogas storage, if user make use of biogas in case of biogas stove which the biogas pressure will be drop below in conjunction with floating cover will synchronous drop, when the floating cover has full of biogas which supernumerary of biogas automatic overflow to outside from bottom side of floating cover, it can not be appear with over high pressure thereby cause the tympanites of floating cove burst or biogas pipe burst and never has such phenomenon happen, the floating cove type biogas digester has reliable safe security.

根据沼气实际使用需求用量来做相应配置，可以保持长期在恒压状态沼气气压，浮罩顶部是密封的，当浮罩式沼气池发酵时所产生的沼气使浮罩上升并储存沼气，如果用户在用沼气炉灶用气时沼气压力将随之下降的同时浮罩也随着气压的下降而降低，当浮罩充满沼气时多余的沼气会自动从浮罩底部溢出，不会出现因气压过高造成鼓池、爆裂或爆管现象发生。浮罩式沼气池具有非常可靠的安全保障。
