Centrifugal rotational flow hollow nozzle device suitable for reverse flow cooling tower of air conditioning system

The utility model provides a centrifugal rotational flow hollow nozzle device suitable for a reverse flow cooling tower of an air conditioning system. The centrifugal rotational flow hollow nozzle device comprises a centrifugal rotational flow hollow nozzle, a conical water distribution disc, a V-shaped connecting rod, a water distribution disc height adjusting hole and a water distribution hole.When cooling water flows out of the centrifugal rotational flow hollow nozzle, an umbrella-shaped spraying effect is achieved, and the cooling water covering area is in a circular ring shape. At the moment, cooling water collides with the water distribution disc below the nozzle, secondary spraying flow distribution is conducted through the water distribution disc, and the spraying characteristicsthat the spraying coverage area is wider, the liquid drop splashing effect is good, and no obvious spraying flow blank area exists are formed. The distance between the water distribution disc and theoutlet of the nozzle can b
