[0023] The fuselage 1 is provided with a fixing tube 10 at the upper end surface, and a screw cover 11 is screwed on the fixing tube 10. A connecting block is provided at the bottom of the screw cover 11, and a snap block is inserted inside the connecting block.

[0024] Furthermore, the first motor 13 forms a locking and limiting structure through the locking block, the limiting rod 12, the nut and the connecting block, and the activated carbon column 14 forms a rotating structure in the fuselage 1 through the output shaft under the action of the first motor 13, thereby ensuring that the biogas can fully contact it through the rotating activated carbon column 14, thereby increasing the utilization rate of the activated carbon material.

[0027] Working principle: When using the biogas-specific denitrification equipment, first, biogas is introduced into the fuselage 1 through the air inlet pipe 2. During the biogas introduction process, the impurities in the biogas can be preliminarily filtered through the filter 4, and the filtered impurities are collected in a centralized manner through the collection box 7.

After the biogas is filtered twice, it can be dried by the desiccant in the storage box 15. At the same time, the second motor 17 can be started, and the output shaft of the second motor 17 drives the rotating shaft 18 to rotate through the coupling, so as to drive the rotating blades 19 to move through the rotating shaft 18, thereby increasing the movement of the biogas after denitrification under the action of the rotating blades 19, thereby increasing the drying rate of the biogas in the fuselage 1.
