Against such problems as blocking

central hole

easy-falling-off lower plate

over large water droplet and uneven spraying that easily occur in the traditional spraying equipment

a novel GX type centrifugal spraying device was developed and its actual application and performance test were carried out.Results showed that

under various conditions

the average of the uniform distribution coefficient of spraying water for this new type device was between 0.1 and 0.3

indicating the device has good hydraulic performance.Applying this new type device to a natural draft cooling tower

the outlet circulating water temperature was 0.71 ℃ lower than that of the system without this device

thus the standard coal consumption of the unit was reduced by about 0.8 g/(kW·h).
