Device for liquid atomization and fluid blending
Abstract
Abstract This disclosure relates to a method and a device for efficiently atomizing liquids into extremely fine cloudlike particles by discharging fluid thru one or more apertures located, preferably between 1 mm. and 100 mm., above a controllable free surface of the liquid to be atomized. The area adjacent to the fluiddischarging aperture is linked to the liquid by at least two distinct wettable surface means. In operation the liquid, at least partially due to pressure differential, adhesion, cohesion, surface tension and capillarity, rises to and surrounds completely the apertures. These factors and means, along with a means of achieving a wide flat-fan fluid dispersion and a means of varying the number of apertures, produce a uniformly fine, highly stressed film on all sides of the apertures and results in excellent metering control, uniform atomization, efficient dispersion and atomization, and clogfree operation. Secondary blending of the emitting fluid with atomized liquid in the vicinity of the aperture by the removal of one or more of the said liquid wettable surface means, permitting certain apertures to emit only fluid while the remainder are emitting atomized liquid, provides added efficiency and control.
