Abstract
An automatic high-speed rotary atomizing device, comprising a rotary spray head with an upper portion and a lower portion, the upper portion is connected to pressurized fluid, the lower portion is connected to the upper portion by means of one or more spray nozzles (1, 3) or spray orifices via a bearing (56). The upper portion is stationary. When the pressurized fluid is sprayed out from the spray nozzle, part of kinetic energy of the pressurized fluid generates a counterforce that propels the entire lower portion of the spray head to rotate at a high speed, so as to convert most of the kinetic energy of the pressurized fluid into surface energy that facilitates atomization of water flow when the pressurized fluid hits against a slanted surface or slit of the spray nozzle or passes through an aperture thereof, thereby forming a large-scale atomized, dispersed and swirling system. This automatic high-speed rotary atomizing device has low working pressure, high rotating speed, small and homogeneous fog droplets, and therefore can be widely used in fire extinguishing, flue gas purification, city purification, greenfield watering, landscape decoration, etc.
