Abstract
Pneumatic nebulizer and method for uniformly supplying variable small amounts of flowable liquid into a gas flow to form a stable dispersion having the appearance of a natural fog and consisting essentially of microscopic particles of said liquid dispersed in said gas. The nebulizer comprises a means for controlling the rate of flow of said liquid, a mixing element having one or more narrow liquid orifices through which the liquid is supplied in uniformly fine amounts, a filming surface onto which the liquid is drawn and stretched and a gas orifice which introduces the stretched liquid film into the gas flow. The mixing element, which may be a replaceable unitary element, comprises a filming surface having an affinity for the liquid being dispersed in the gas flow, at least one liquid passage adapted to receive a regulated supply of said liquid and having a very small exit orifice on said filming surface and adapted to transmit said liquid to said filming surface, and a gas orifice communicating with an edge of said filming surface and spaced from said very small liquid orifice and adapted to receive liquid from said filming surface in the form of the thinnest continuous filament or film of said liquid which can be drawn across said surface by the cohesive force between the liquid being dispersed at said gas orifice and the liquid on said surface.
