沼气脱硫器，是一种沼气专用运转装置，其特性在于脱硫瓶内的进气口上衔接一个悬空的多孔管，多孔管尽可以长地横向伸入脱硫瓶内腔，多孔管上密布小孔，小孔的孔径小于氧化铁小颗粒的直径。利益在于多孔管的设置，使与氧化铁小颗粒之间的出气道面积大为增大，则出气量大；其次水分部分泡烂氧化铁颗粒但仍能留存部分出气孔；再次在于多孔管悬空设置，使脱硫瓶内水分积压在悬空多孔管下方，不容易泡烂多孔管周边的氧化铁颗粒

Gas desulfurization devices, is a kind of special biogas operation device, the utility model is characterized in that the air inlet of desulfurization bottle connected by a suspended porous pipe, perforated pipe can long transversely inserted desulphurization bottle cavity, porous tube densely distributed with small holes, the hole diameter is smaller than the diameter of the small particles of iron oxide. Interest in porous pipe set between the iron oxide and small particles from the airway area was increased, while out of gas; secondly water soaked iron oxide particles but still retained part of porosity; porous tube is again suspended, so that water bottle desulfurization backlog in the suspended below the perforated pipe, not easy to iron oxide particle soaked porous tube surrounding
