Abstract
A mist generator for producing mists having fine particle sizes which includes a jet for aspirating a liquid such as water, oil, paints, liquid suspensions and the like, a series of chambers through which said mist is successively passed and deflecting the flow of said mist by baffles, auxiliary gas jets and the like to remove the larger mist particles.
Claims19
A mist generator comprising a housing having a base and a peripheral wall structure extending therefrom, means for aspirating a liquid within said housing to form a mist, said means including a nozzle having an outlet for the discharge of gas under pressure and means communicating with a liquid source for the aspiration thereof in response to gas discharged from said nozzle, a first sleeve in said housing and surrounding said nozzle to form a first chamber adjoining the outlet, a cylindrical member extending from said first sleeve to form a second chamber of smaller area than the first chamber, said mist flowing successively from the first chamber to the second chamber, and second sleeve means communicating with said cylindrical member and including a third chamber for confining said mist and including openings for discharging it into said housing in a direction angularly disposed relative to the direction of emergence of gas from the nozzle, said mist then being discharged from said housing said nozzle extending from said base and terminating in a frustoconical end portion, said first sleeve surrounds said nozzle and forms said communication means for aspiration of liquid into the first chamber, the end of said first sleeve extending at least to the end of the nozzle and having an inwardly formed taper terminating beyond the end of the nozzle in an opening smaller than the cross sectional area of said nozzle and said cylindrical member extends from the first sleeve and has an opening corresponding in cross sectional area to the cross sectional area of the terminal opening of said first sleeve, and said openings for discharging the mist from said third chamber being disposed below the end of said second chamber, said generator further including a baffle surrounding at least a portion of said second sleeve and spaced therefrom, the lower end of said baffle extending below the last said openings to form a circuitous path for the flow of said mist from said third chamber to said housing.
A mist generator comprising a housing having a base and a peripheral wall structure extending therefrom, a nozzle centrally disposed within and extending from the base of said housing and having an opening extending therethrough, means for feeding compressed gas upwardly through said nozzle opening, a sleeve surrounding said nozzle, said housing adapted to retain a liquid about the base of the sleeve, said sleeve extending beyond the upper end of said nozzle and terminating in a section having an internal diameter smaller than the internal diameter of the remainder of the sleeve and thereby forming a first chamber adjoining the end of the nozzle and a second chamber communicating with the first chamber, conduit means to facilitate the flow of said liquid into said first chamber in response to the flow of gas through said nozzle, means including a closed chamber coupled to and extending below the second chamber and having radial openings at the base portion thereof and below the outer end of said second chamber and a baffle at least partially surrounding the last said chamber in spaced relationship thereto and overlying the openings therein for modifying the direction of flow of said mist from said second chamber into said housing and means on said housing for discharging said mist.
A mist generator comprising means for producing a mist, means defining a closed chamber, the first said means extending into said chamber for discharging said mist at a point within said chamber, said chamber defining means having a plurality of openings disposed rearwardly of the point of discharge of said mist into said chamber, a baffle surrounding said chamber defining means and overlying said openings to form a circuitous path for the flow of said mist and a housing surrounding said chamber defining means and including an outlet for discharging said mist.
A mist generator comprising means for producing a mist, means defining a closed chamber, the first said means extending into said chamber for discharging said mist at a point within said chamber, said chamber defining means having a plurality of openings disposed rearwardly of the point of discharge of said mist into said chamber, a housing surrounding said chamber and having an outlet for discharging said mist and means for feeding a jet of gas into said housing to impart circular motion to said mist and cause the larger particles through the centrifugal force imparted thereto to strike said housing.
