首先要知道沼气中含有水分和硫化氢，水分对沼气的利用影响大。沼气中的水分与硫化氢共同作用能加速管道及阀门、流量计等的腐蚀，为正常供气延长设备的使用寿命。在输气管路中须安装沼气脱硫器，所以在进行沼气脱硫时需要同时进行脱水处理，去除沼气中的水分和硫化氢，增加产出沼气的质量。
Firstly, it is important to know that biogas contains water and hydrogen sulfide, and water has a significant impact on the utilization of biogas. The combined action of moisture in biogas and hydrogen sulfide can accelerate the corrosion of pipelines, valves, flow meters, etc., extending the service life of equipment for normal gas supply. It is necessary to install a biogas desulfurizer in the gas transmission pipeline, so dehydration treatment needs to be carried out simultaneously during biogas desulfurization to remove moisture and hydrogen sulfide in the biogas and increase the quality of produced biogas.
沼气脱硫器的脱硫方法有湿法和干法脱硫两种。干法脱硫具有工艺简单、成熟可靠、造价低等优点，并有较好的净化效果。其中最受欢迎的是使用脱硫剂。
There are two desulfurization methods for biogas desulfurizers: wet and dry desulfurization. Dry desulfurization has the advantages of simple process, mature and reliable, low cost, and good purification effect. The most popular one among them is the use of desulfurizers.
沼气脱水器外部采用碳钢结构内部防腐处理，当沼气以一定的压力从上部的进气口进入后，水滴在离心力作用下旋转与脱水器壁发生碰撞，使水滴失去动能与沼气相分离，以达到除尘和脱水的目的。而后器内的水滴沿内壁向下流动而存于装置底部，并定期排除。
The exterior of the biogas dehydrator adopts a carbon steel structure with internal anti-corrosion treatment. When biogas enters from the upper inlet at a certain pressure, the water droplets rotate and collide with the wall of the dehydrator under centrifugal force, causing the water droplets to lose kinetic energy and separate from the biogas, achieving the purpose of dust removal and dehydration. The water droplets inside the device flow downwards along the inner wall and are stored at the bottom of the device, and are regularly discharged.
从软体沼气池中出来的沼气中含有大量的水气、硫化氢等有害气体。沼气经过初步脱水除尘后然后进入脱硫器，利用合理的反应条件可将沼气中的硫化氢脱至200ppm以下。
The biogas coming out of the soft biogas digester contains a large amount of harmful gases such as water and hydrogen sulfide. After preliminary dehydration and dust removal, biogas enters the desulfurizer. By using reasonable reaction conditions, hydrogen sulfide in biogas can be removed to below 200ppm.
脱硫后的沼气进入沼气增压风机进行增压输送。
The desulfurized biogas enters the biogas booster fan for pressurization and transportation.
