ABSTRACT:
Pneumatic nebulizer and method for uniformly introducing 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 liquid particles of said liquid dispersed in said gas. The nebulizer comprises a mixing element for introducing the liquid in uniformly fine amounts into the gas flow. The mixing element, which preferably is a replaceable unitary element comprises two contacting members having conforming surfaces which supportingly contact each other over a substantial portion of the surfaces of each to prevent compression therebetween. At least one shallow liquid passage is provided between the members of the mixing element said passage having an entrance in communication with a liquid supply chamber and having an exit orifice in communication with a gas passage to provide at least one stable liquid orifice for metering uniform predetermined amounts of liquid into a gas flowing through said gas passage. Said shallow liquid passage is formed between the said members by providing the surface of one or both members with at least one scratch, grind, etch, impression or the like, or by interposing a discontinuous inert coating or series of spaced shims or other means, to form at least one recess having a depth of about 0.01 inch or less to provide at least one stable, liquid passage for introducing uniform fine amounts of liquid from a liquid supply into the gas passage for admixture with the gas flowing from a gas supply.
