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.
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.
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%.
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.
