The utility model relates to a nice and warm cloth vapour system is carried, is crossed to steam of outer hot type gyration activation furnace of active carbon. Including exhaust -heat boiler, steam valve, first defeated steam pipe, a expansion joint, steam superheater, B expansion joint, second defeated steam pipe, C expansion joint and the cloth vapour house steward who connects gradually. Clothvapour house steward passes the stove hood, follows the length that stretches into in the stove caudad stove and establishes a bearing supporting device with a rotation of rotary furnace for 2~3 meters for 45~56 of rotary furnace length, every, installs cloth vapour house steward and locates with one heart at rotary furnace, and it can freely be stretched out and drawn back in the bearing, clothvapour house steward from the stove caudad stove in one 0.5~0.7 meter equipartition of 3 meters everys downwards and the cloth vapour branch pipe of perpendicular rotary furnace axis, steam jet is installed to its port, lets to spout the steam vent surperficial from rotary furnace inner wall 150mm~200mm. Steam through the nozzle concentrate spout the carbomorphism material that drops on the furnace body bottom on, make both fully contact, fully react to improve the quality and the output of active carbon.
