Biogas needs to be pretreated before entering the biogas generator unit. In addition to a large amount of methane and carbon dioxide, the biogas produced by feces also contains other components such as hydrogen sulfide, impurities, water, nitrogen oxides and siloxanes. The biogas produced by fecal anaerobic fermentation has a large content of hydrogen sulfide, which will corrode the equipment at the back end. Therefore, the biogas desulfurization treatment was carried out.

未经处理的沼气不符合发动机气体品质的要求。沼气直接进入发动机，可能会引起功率波动、机组敲缸、停机甚至爆炸。若气体只是做了简单的处理，水分、含尘量、压力、温度等均不符合机组要求。由于积水导致了凝结水在管道的大量聚集，机组的可用率和发电功率大幅度下降；含尘量过高导致压力损耗过大，且机组内部缸体损耗严重；压力、温度等不符合机组要求，机组频繁跳机，可用率大幅下降且增加了维护检修成本。而经过改造后的气体预处理，机组的发电量可以增加70%。所以，气体品质处理的效果如何，直接影响到终的机组工作效率，从而影响收益。所以选用好的预处理设备进行气体的除湿、除杂、稳压、恒温等等工作是保证效益的前提。

Untreated biogas does not meet the requirements of engine gas quality. Biogas directly enters the engine, which may cause power fluctuation, unit cylinder knocking, shutdown or even explosion. If the gas is simply treated, the moisture, dust content, pressure and temperature do not meet the requirements of the unit. Due to water accumulation, a large amount of condensed water is accumulated in the pipeline, and the availability and power generation of the unit are greatly reduced; Excessive dust content leads to excessive pressure loss and serious loss of cylinder block inside the unit; The pressure, temperature, etc. do not meet the requirements of the unit, the unit frequently trips, the availability rate drops significantly, and the maintenance cost is increased. After the gas pretreatment, the power generation of the unit can be increased by 70%. Therefore, the effect of gas quality treatment will directly affect the working efficiency of the final unit and thus affect the income. Therefore, selecting good pretreatment equipment for gas dehumidification, impurity removal, pressure stabilization, constant temperature and other work is the premise to ensure efficiency.

沼气发电机组对使用环境及沼气的基本要求：

The basic requirements of biogas generator set for use environment and biogas:

1.燃气进气压力为2-10kpa,发电机组的气体压力过高或过低则需加调压阀或增压设备；

1. The gas inlet pressure is 2-10kpa. If the gas pressure of the generator set is too high or too low, the pressure regulating valve or booster device shall be added;

2.燃气中不含游离水和大于5μm的游离物质，燃气中硫化氢含量需低于10ppm；

2. The fuel gas does not contain free water and more than 5 μ M U.M, and the hydrogen sulfide content in the gas shall be less than 10ppm;

3.机组一般使用环境：温度5℃~35℃，海拔高度≤500m；

3. General operating environment of the unit: temperature 5 ℃ ~ 35 ℃, altitude ≤ 500m;

备注：燃气中硫化氢含量过高时，对燃气机组零部件会造成一定的腐蚀，影响机组正常使用及机组使用寿命。。

Note: when the hydrogen sulfide content in the gas is too high, it will cause certain corrosion to the parts of the gas unit, affecting the normal use of the unit and the service life of the unit..
