The invention provides a centrifugal rotational flow hollow spray nozzle device suitable for a reverse flow cooling tower of an air conditioning system. The centrifugal rotational flow hollow spray nozzle device comprises a centrifugal rotational flow hollow spray nozzle, a conical water distribution disc, V-shaped connecting rods, water distribution disc height adjusting holes and water distributing holes. When cooling water flows out of the centrifugal rotational flow hollow spray nozzle, an umbrella-shaped spray effect is formed, and the cooling water covering area is in a circular ring shape. At the time, the cooling water collides with the water distribution disc below the spray nozzle, secondary spray flow distribution is carried out through the water distribution disc, and the sprayfeatures that the formed spray covering area is wider, a liquid drop splashing effect is better, and no obvious spray flow bland area is formed are formed. The distance between the water distributiondisc and an outlet of the spray nozzle can be adjusted through adjusting holes in the connecting rods, and thus the spray features and the liquid drop splashing feature can be adjusted to a certain degree. The centrifugal rotational flow hollow spray nozzle device is simple in structure, convenient and fast to assemble and disassemble and easy to clean and maintain, and has great help to improvement of the efficiency of the reverse flow cooling tower.
