The utility model relates to a filtration of gas flow (especially air current). Specifically, the utility model relates to a granule charging system and gas filtration system for the granule charging system and the gas filtration method of gas filtration system. A discharge device (12A -12C) and earth potential device that is used for the granule charging system of gas flow pipeline to include can carry the current potential. In addition, exist being used for with the DC current potential preach to discharge device (12A -12C) and with the earth potential conduct to earthing device (14A -14D) for being contained in with near the charging district discharge device (12A -12C) the device that the interior granule of gas flow pipeline charges. According to the utility model discloses, discharge device (12A -12C) is including the corona discharge component of one or more convergent. The utility model discloses the permission is charged for the granule at electret filter unit's etc. The upper reaches effectively.
