Filed: 1982-07-19
Abstract: PURPOSE:To reduce the size of the particles to be sprayed and to improve atomizing efficiency by circulating the liquid drops stuck and deposited on a holder for holding a collision body to the rear side of a liquid film. CONSTITUTION:The liquid pressurized by a pump 1 is linearly sprayed from a single holed nozzle 2 to the collision surface 4 in the smooth flow region of a collision body 3. The shape of the radial liquid film 6 formed on the surface and the grain size of fine particles vary with the ejection velocity of the liquid flow 5 thereof and the angle of the surface 4.
