Centrifugal rotary nozzle for pipeline disinfection and working method

The invention relates to a centrifugal rotary nozzle for pipeline disinfection and a working method. The centrifugal rotary nozzle for the pipeline disinfection comprises horizontally-arranged water inlet pipelines and a plurality of fixing jackets arranged in the length direction of the water inlet pipelines at intervals, wherein motors and rotating shafts which are arranged at the output ends ofthe motors and penetrating through the water inlet pipelines from top to bottom are arranged on the fixing jackets, the lower portions of the water inlet pipelines are connected with wear-resisting pipe sleeves communicating with through openings in the lower portions of the water inlet pipelines, the peripheries of the lower portions of the wear-resisting pipe sleeves are sleeved with conical shell sleeves rotating along with the rotating shafts, the lower ends of the rotating shafts are fixedly connected with rotating blades, and small round holes used for spraying water are distributed inthe conical shell sleeves.
