| 干法脱硫是一种简易、高效、相对低成本的脱硫方式，一般适合用于沼气量小，硫化氢浓度低的沼气脱硫。干法脱除沼气气体中硫化氢（H2S）的设备基本原理是以O2使H2S 氧化成硫或硫氧化物的一种方法，也可称为干式氧化法。 Dry desulfurization is a simple, efficient and relatively low-cost desulfurization method, which is generally suitable for biogas desulfurization with small amount of biogas and low concentration of hydrogen sulfide. The basic principle of equipment for dry removal of hydrogen sulfide (H2S) from methane gas is a method of oxidizing H2S to sulfur or sulfur oxides by oxygen, which can also be called dry oxidation method. 干法设备的构成是，在一个容器内放入填料，填料层有活性炭、氧化铁等。气体以低流速从一端经过容器内填料层，硫化氢（H2S）氧化成硫或硫氧化物后，余留在填料层中，净化后气体从容器另一端排出。 The dry process equipment consists of filling in a container with activated carbon and iron oxide as the filling layer. The gas passes through the packing layer of the container at a low flow rate. After hydrogen sulfide (H2S) is oxidized to sulfur or sulfur oxide, the remaining gas is left in the packing layer. After purification, the gas is discharged from the other end of the container. |
