This invention relates to improvements in fluid mixing methods and means, and more particularly to an improved method of and arrangement for increasing the time of mix- 'ing contact of a gas with a liquid, the present device being adapted particularly for admixing ozone with water for sterilization purposes.
An object of the present invention is to pro- Y 10 :Vide a method for increasing or prolonging the time of contact between a. gas and a liquid that a maximum length of such mixing passage'may be disposed within a given limited area.
the present example, an object of the invention is attained in the combination of a gasfit liquid injector and a mixing container or tower, with a spiral mixing passage connect ingthe injector with, the space within the tower.
Further objectslandadvantages of the invention will appear from the followingdescription, considered in connection with the accompanying drawing, in which Fig. 1 is a sectional view of an assembly adapted for use with an-ozone generator, and embodying the principles of the present invention.
Referring by reference characters to the drawing there is provided at a a liquidinlet into the mixing nozzle which may be desig-- nated as an injector or ejector nozzle, the liquid entering through the inlet acontinuing downwardly through aVenturi tube at the point 0, at which point there is produced, according to known principles, a suction within the body of the injector. At 7) there is provided a gas inlet, in the present example It is understood that the inlet 6 may be and is by preferenceconnected to a suitable source of supply of ozone, such as an ozone generator, v(not shown); Connected to the outlet portion of; the injector fitting is'a spiral'pipe d, shown .as consistingof a substantial number of'overe lying turns, and preferably formed of flexible metallic tubing. The spiral pipe or passage cl is provided with an outlet at e which may consist of a cap affixed to the discharge end ofthe passage and provided with a substantial number of peripherally disposed openings.
. As' will appear from the drawing: the spiral pipe (Z is disposed within a towerf,
elongate cylindrical form, by preference disposed vertically substantially asshown and provided with an outlet g, from which the ozonized water'may bedrawn or directed as desired. As a'provision for draining'the con-. tents of the tower f -and to permit cleaning thereof, there isprovided at a drain outlet provided with a suitable detachableiclosure fmember, such asa threaded cap.- More'particularly stated with reference to i duced through the opening a, and proceeds into the-venturi tube, the suction created by the ejector-action of the Venturipassage,
60* the tower being preferably; a. container of creates a suction at 0,-and henceat 72, causing a flow of ozone or other gas Into the fitting.
Theozone, for example, being drawn in about the inlet nozzle, to. thev Venturi passage, is picked-up by the inflowing liquid, the velocity of which causes an intimateadmixt-ure of the ozone and water, whlch then proceeds,
partly under the influiencebf gravityvand partly under-the influence of inertia ofthe incominglstreams, downwardly through the spiral pipe (Z. The turbulence resulting from the action of the ejector and venturi persists;
into and to a certainextent through the pipe (Z,with the result that, due to the relatively ozone "and airfbecome thoroughly mixed, the ozone being suspended and to a certain extent dissolved in the water as it issues from the opening r I It will be'apparent. that the dcon- Lsisting of the greatnumberof overlying 'congreat nuinberof turns in the spiral pipe, the
volutions provides a greater length of mixing passage beyond the injector fitting, than would be possible if such passage were formed of one or a few lengths of straight tubing. The curvature of the convolutions is by preference as great as is permitted by the diameter of the cooling tower so as to avoid any sharp turns or bends between the injector fitting and distributor outlet 0. It is, of course, understood that space requirements, such as the height of the tower f, as well as its diameter, are often dictated by available space for given installations and the desirability of forming apparatus of this type in standard commercial sizes.
While the foregoing description has been directed to a particular exemplary embodiment of the invention designed for affecting admixture of ozone and water, it will be understood that the principles herein described are applicable generally to devices for causing admixture or solution of gas and liquids. It will further appear that the present device is susceptible of certain changes in the parts and their combinations without departing from the spirit and full intended scope of the invention, as hereinafter claimed.
I claim as my invention:
1. In a device for mixing ozone and water, an elongate vertical container for the fluids after mixing, a fitting carried by the upper end of said container, provided with spaced, angularly arranged inlets for the ozone and water to be mixed and including a Venturi passage for bringing the fluids into initial mixture, a water nozzle having a restricted end projecting into the inlet of said Venturi passage, a spiral conduit within said container directed from said fitting to the opposite end thereof, a spray head at the discharge end of said conduit, provided with discharge openings directed radially, and along the bottom of the container, and a discharge port directed from said container and disposed near the upper end of said container.
2. In a device for mixing ozone with water, a vertical mixing tower, an inlet fitting carried near the top of said tower and having separate inlet ports for water and ozone, a member carried by the fitting having a Venturi passage therethrough, provided with an inlet adapted to receive water and ozone, a water nozzle projecting into said Venturi passage, the passage being arranged to conduct and mix both of thesaid fluids, a spiral tube disposed within the tower and having its inlet connected with the discharge of said fitting and with said Venturi, said tube consisting of a plurality of overlying turns of tubing, terminating in a downwardly projecting discharge end disposed substantially at the lower portion of said tower, whereby the fluids are adapted to flow downwardly through said tube, from the upper to the lowor end of said tower, the discharge end of MARION G. GNAU.
