Abstract

This invention relates to a device for forming a mist or fog having a convex surface which receives and expands a fluid delivered thereto. The convex surface of the device has a number of circular protrusions spaced peripherally thereon, separated by a number of slots having holes therein. The holes communicate with an inner cylindrical chamber. Suction is produced through the holes when the fluid stream passes over them, to automatically add a further fluid to the fluid being expanded by the device. A cylindrical sleeve surrounds and protects the device. The device is supported in the cylindrical sleeve, either in front of a nozzle by an annular structure, or by a bent tube held in the cylindrical sleeve in front of the device, or in a venturi. When fluid from the nozzle or entering the cylindrical sleeve is expanded by the convex surface, it pulls a further fluid through the slots to mix with the injected fluid separated from the convex surface of the device at greater speed, thus forming a mixed fog of fluid.

Dependent claims

A fog atomizer comprising:

a first body having a plurality of circular protrusions formed therein;
said plurality of circular protrusions spaced peripherally over a section of maximum diameter of said first body;
a cylindrical sleeve having structural means therein holding said first body in axial alignment therein;
an axial axis of said cylindrical sleeve being coincident with an axial axis of said first body;
said first body further including a plurality of slots, having a given width, formed between said plurality of circular protrusions;
a plurality of holes formed in said slots;
an inner cylindrical chamber in said first body;
said plurality of holes having centers which are coincident with the section of maximum diameter of said first body, to said holes communicate said slots with said inner cylindrical chamber, which inner cylindrical chamber has an axis coincident with said axis of said first body;
said inner cylindrical chamber having an inner end which is closed, and an exterior end which is opened, whereby the flow of a fluid in said cylindrical sleeve expands over said first body surface, so as to produce suction over said holes to automatically pull a further fluid from said inner chamber to mix with said fluid in said cylindrical sleeve, which is spaced from said circular protrusions and said slots;
and
said cylindrical sleeve surrounding said first body.

A fog atomizer comprising:

a body having a plurality of circular protrusions formed therein;
said plurality of circular protrusions spaced peripherally over a section of maximum diameter of said body;
said body being held in axial alignment by structural means, in front of a convergent-divergent nozzle;
an axial axis of said convergent-divergent nozzle being coincident with an axial axis of said body;
said body further including a plurality of slots, having a width, formed between said plurality of circular protrusions;
a plurality of holes formed in said slots;
an inner cylindrical chamber formed in said body;
said plurality of holes having centers which are coincident with the section of maximum diameter of said body, to said holes communicate said slots with said inner cylindrical chamber, which inner cylindrical chamber has an axis coincident with said body axis;
said inner cylindrical chamber having an inner end which is closed, and an exterior end which is opened, whereby the flow of a fluid coming from said nozzle expands over said body surface, so as to produce suction over said holes, to automatically add a further fluid to a fluid spray from said convergent-divergent nozzle which is spaced from said circular protrusions and said slots;
and
a cylindrical sleeve surrounding said nozzle and said body;
said cylindrical sleeve having a plurality of air passages formed therein and being supported by an annular structure, secured to an external surface of said nozzle, whereby said fluid spray is expanded upon exiting from said nozzle and passing over said body.
