APPARATUS FOR THE INCORPORATION OF A LIQUID WITH A GAS Filed April '7, 1933 INVENTOR.

Patented Dec. 3, 1935 UNITED STATES PATENT OFFICE Pierre Georges Vicard, Lyon, France Application April 7, 1933, Serial No. 664,997 In France April 25, 1932 2 Claims.

This invention relates to an apparatus for the rapid and complete incorporation of a liquid with a gas, such apparatus providing means for elfecting intimate mixtures, emulsions or combinations in the chemical 'sense of the word of a liquid and a gas such as may be required for various purposes in industry for example for the conditioning of the atmosphere in factories, workshops,

public halls or for the condensation of dust etc.

For the obtention of the result desired a jet of liquid at a low pressure is directed against or on blades of a particular shape as will hereinafter be described, the said blades being arranged on the periphery of a drum or wheel which is caused to rotate at high speed in the gaseous medium (air for example) with which the said liquid is to be incorporated.

The efficaciousness of the improved apparatus is due to the fact that the feed of the jet is effected at a low pressure against blades which have both cutting and shock producing properties due to the particular sectional shape given to said blades, which are given a very high speed of movement. This shape is such that the whole of the liquid supplied by the jet is finely atomized, no secondary condition being present which might prevent the perfect sheering of the jet or jets into very small drops and the complete atomization by shock of each separate drop.

To obtain this result it is necessary that the blades fulfil the following conditions (a) that they present to the jet an edge which cuts through the jet without scattering or throwing back any fraction thereof outside the zone of encounter.

(b) that their surfaces of encounter that is to say their front faces in the direction of forward movement, are combined with their cutting edges in such a way that the total amount of gas swept by the passage of the blades flows in the direction of penetration of the liquid, which may be effected for example in the manner which will be described by giving to said surfaces of impact a suitable inclination with respect to the cutting edges.

The annexed drawing diagrammatically illustrates an example of construction of the invention. 11 indicates a part of a drum or wheel seen in side view on which are shown two of the blades b, b mounted on the periphery of the drum. At is shown the jet of liquid, water for example to be incorporated with the flow of the ambient gas, air for example.

The drum turns in the direction indicated by the arrow I, and the liquid to be incorporated flows in the direction indicated by the arrow 2. 5

The jet of liquid is cut by the edge d of each blade, the drop which is detached by the cutting action is struck by the face e of the said blade and under the shock of this impact this drop is disintegrated and finely atomized, and escapes intimately mixed with the gas stream.

The direction of the jet of liquid with respect to the blade drum may be variable. There can be several jets instead of a single one.

The number of drums utilized in an apparatus may also be variable according to the number of liquids to be atomized. Also on the same drum and on the same side as the cutting edges jets of different liquids succeeding one another in predetermined order can be arranged. 0

What I claim as my invention and desire to secure by Letters Patent of the United States is:-

1. Apparatus for the incorporation of a liquid in a gas comprising in combination, a rotary member, a series of blades having sharp cutting edges and considerably and uniformly curved working surfaces mounted on said rotary member with said working surfaces extending substantially radially relative to the periphery of said rotary member, and a pipe adapted to feed liquid in a direction substantially normal to the direction of movement of said blades on to said sharp cutting edges during the rotation of said rotary member.

2. An apparatus for the incorporation of a liquid in a gas, comprising a rotary member, a plurality of blades mounted on the periphery of said member and extending in a radial direction, the leading edge of each blade being in the form of a sharp cutting edge, means for directing a stream of liquid against said blades in a direction substantially parallel to the axis of rotation of said rotary member, and each blade having a curved working surface extending rearwardly and laterally away from said cutting edge to impact and disperse the portion of the stream of liquid severed by the cutting edge into the atmosphere surrounding the blade.
