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

The invention provides a centrifugal rotational flow hollow nozzle device suitable for a counter flow cooling tower of an air conditioning system. The centrifugal rotational flow hollow nozzle devicecomprises a centrifugal rotational flow hollow nozzle, a conical water distribution disc, a V-shaped connecting rod, water distribution disc height adjusting holes and water distribution holes. Aftercooling water flows out through the centrifugal rotational flow hollow nozzle, an umbrella-shaped spraying effect is formed, and the coverage area of the cooling water is in a circular ring shape. Atthe moment, the cooling water collides with the water distribution disc below the nozzle, secondary spraying flow distribution is carried out by the water distribution disc, so that spraying characteristics of wider spraying coverage area, good liquid drop splashing effect and no obvious spraying flow blank area are formed. The distance between the water distribution disc and an outlet of the nozzle can be adjusted through
