除大量甲烷和二氧化碳外,从粪便中产生的沼气还包含其他成分,例如硫化氢,杂质,水分,氮氧化物和硅氧烷。粪便厌氧发酵产生的沼气包含大量的硫化氢,会腐蚀后端的设备,因此要将其脱硫,进行沼气发电机组预处理。
In addition to large amounts of methane and carbon dioxide, biogas produced from faeces contains other components such as hydrogen sulfide, impurities, moisture, nitrogen oxides and siloxanes. Biogas produced by anaerobic fermentation of faeces contains a large amount of hydrogen sulfide, which will corrode the back-end equipment. Therefore, it is necessary to desulfurize and pretreat the biogas generator set.
未经处理的沼气不符合发动机气体质量的要求。沼气直接进入燃气发动机,这可能引起功率波动,设备爆震,停机甚至爆炸。如果仅对气体进行处理,则水分,粉尘含量,压力,温度等均不能满足设备要求。
The untreated biogas does not meet the requirements of engine gas quality. Biogas directly enters the gas engine, which may cause power fluctuation, equipment knock, shutdown or even explosion. If only the gas is treated, the moisture, dust content, pressure and temperature can not meet the equipment requirements.

由于管道中冷凝水的积聚,发电机组的可用性和发电量大大减少了;灰尘含量过多会导致压力损失过大,并严重损坏设备的内部气缸;压力和温度不符合要求根据设备要求,设备经常跳闸,可用率显着下降,并且维护和维修成本增加。经过改进的气体预处理后,该装置的发电量可提高70%。
Due to the accumulation of condensate water in the pipeline, the availability and power generation of the generator set are greatly reduced; excessive dust content will lead to excessive pressure loss and serious damage to the internal cylinder of the equipment; the pressure and temperature do not meet the requirements. According to the requirements of the equipment, the equipment often trips, the availability rate decreases significantly, and the maintenance and repair costs increase. After the improved gas pretreatment, the power generation of the device can be increased by 70%.
因此,气体质量处理的效果直接影响沼气发电机组的效率,从而影响利润。因此,选择优良的气体除湿,除杂,电压稳定和恒温发电机组预处理设备是确保沼气发电机组良好运行的重要组成部分。
Therefore, the effect of gas quality treatment directly affects the efficiency of biogas generating units, thus affecting profits. Therefore, the selection of excellent gas dehumidification, impurity removal, voltage stability and constant temperature generator pretreatment equipment is an important part to ensure the good operation of biogas generator.
