Nebulizer

摘要

Pneumatic nebulizer for uniformly dispersing variable amounts of flowable liquid in a gas to form a stable dispersion having the appearance of a natural fog and consisting essentially of liquid particles having a maximum particle size below about 20 microns diameter and having an average particle size well below about 10 microns diameter suspended in said gas. The liquid is forced at a variable rate into a gas flow, at an angle thereto, through an orifice having a width which is variable under the effect of gradual changes in the force of said gas and/or of said liquid to stress the liquid prior to contact with the propellant gas, and is contacted with the propellant gas as it emerges from the orifice in stressed condition for conversion into a stable dispersion having the appearance of a natural fog.
