BAFFLE-PLATE FOR COLUMN-STILLS.

To all whom it may concern:

Be it known that I, EMILE GUILLAUME, citizen of France, residing at Paris, in the said Republic, have invented new and useful Improvements in and Relating to Baffie-Plates for Column-Stills, (for which I have obtained a patent in France, No. 5162/ 320,850, hearing date May 26, 1905, and in Republic, No. 4493, of February 7, 1906,) of which the following is a specification.

This invention has for its object certain improvements in the arrangement of battle plates for column stills described in my U. S. Patent No. 732,548.

In order to properly understand the improvements in question it is necessary to refer to the specification and drawings of the said patent. It will there be seen that the characteristic feature of the invention is to constitute along the whole lengtl of the lower edge of the partition 3 of each plate, a continuous sheet of liquid, which, when the vapor rises in the direction indicated by the arrow in the drawings of the said patent, is atomized and projected in a continuous spray which extends longitudinally along the wall 3 and into the space comprised between the latter and the wall of the still facing it. Under these conditions if the ascent of the vapor is stopped, a vertical curtain of liquid along the whole length of the wall 3 .is obtained, which falls onto the lower plate; if the ascent of the vapor recommences, it encounters said curtain so as to produce the continuous spray hereinbefore mentioned and does not permit the vapor to rise from one plate to the next without having passed through the freely falling sheet of liquid.

It may also be pointed out that with this arrangement the following drawbacks may be encountered :,If the discharge of the liquid is such that the orifice 2 is insuflicient,

the plate then becomes filled up to the level of the upper part of the partition 3 and then the liquid overflows this latter; there results from this a diminution of the free space for the passage of the vapor, which is caused to pass through the liquid in the form of bubbles producing an agitation prejudicial to the good working of the aparatus. If, on the contrary, the discharge of the liquid becomes insuflicient to produce a full flow of the liquid through the orifice 2, there will result differences of thickness Specification of Letters Patent.

in the sheet, and-even openings'through which naturally the vapor will tend to pass by preference, without acting in the characteristic manner of the present system. Finally, if theorifice 2 becomes stopped in places in consequence of impurities carried along by the liquid, the same inconvenience as the foregoing will be produced.

The improvements forming the object of the present invention, have for their object to remedy the drawbacks hereinbefore stated.

The invention is illustrated in the accompanying drawings in which, Figure 1 is a vertical sectional view of the invention applied to a rectangular still. Fig. 2 is a like view of a slightly diii'erent form. Fig. 3 is a sect-ion through a cylindrical column, having plates not provided with longitudinal orifices. Fig. 4: is a view similar to Fig. 3 but showing a column having plates, provided with longitudinal orifices. Figs. 5, 6, 7 and 8 are detail views.

According to my invention, apertures 5 are arranged along the partition 3, which apertures prevent the plate filling with liquid up to the top of the partition 3, thus avoiding the first of the drawbacks herein my U. S. Patent No. 732,548 may then be completely suppressed, and all the liquid will flow through the apertures, which will avoid the two otherdrawbacks hereinbefore specified. On the other hand in order to avoid, in case the orifices 2 are retained, the third of the drawbacks in question, that is to say the obstruction of the said orifices, the slope of the plates is directed downward toward the outside of the stills, thus producing a reserve of liquid retaining the refuse which might cause this obstruction.

In the Fig. l are shown the plates of a rectangular column still in which the orifice 2 is retained, butin which it is supplemented by apertures 5 uniformly distributed over the whole length of the vertical partition 3.

These apertures 5 serve as intermediate advantage, over that shown in Fig. 1, of

considerably sim lifyin the construction of the plates, an of defective working, which would arise wit the plates shown in Fig. 1, in'case the quantity of liquid which has to pass through the orifice 2, should not be sufiicient to cause the full sectional flow. to take place. The two upper plates of Figs. 1 and 2 are shown sloping toward the vertical partition 3, that is to say in the direction of flow, and the two lower plates with an inclination in the opposite direction. There is an advantage I in em loying the former when it is desired to re uce to a strict minimum the volume of liquid on the plates, while the second are employed when it is desired to increase this volume a little and especially when it is desired to regularly withdraw, to the outside of the still, liquid from these plates. Further, b the use of the latter, the discharge ori ces 2 and 5 run less risk of becoming stopped because any refuse capable of doing this will, with that construction, preferabl gravitate toward the external part of t e plates, that is to say toward 6. In both cases, however, the volume of liquid in action over the whole of the plates of a column of given production, always remains much less, relative to its hourl production, then when scrubbing pl'ates of an ordinary type, either perforated or dished ones are employed.

In Figs. 3 and 4, the left hand part represents the external plates 7, with a slope leading toward the exterior wall of a cylindrical column, and the right hand part represents the plates with a slope in the opposite direction; some of the internal plates 8 are shown slightly convex and the others slightly concave. What has beenheretofore stated relative to the selection of the direction of inclination for the 1plates shown in.

Fi s. land 2, applies e ua sh wn in Figs. 3 and 4;.

In Fig. 5 small grooves 9 are shown, starting from the base of the apertures 5, which grooves were made in the first experiments in .order to facilitate the uniform distribuy to the plates tion of the liquid over the whole length or,

greater security avoi ing the possibility periphery of the lower edgeof the partition 3; t ese grooves which may be simply roduced by means of a gravers chisel a 0rd of the desired result being obtained but they are not indispensable.

Figs. 6, 7 and 8, represent a form of the openings provided with a shield 10, formed by cutting the metal of the portion 3 on three sides, and bending the tongue thus formed out the lane of said portion, in order to prevent t e passage of, a portion of the' steam orvapor through the apertures 5 iii it is feared that such a-passage might take p ace. I

The shields 10, above specified may be turned either toward the exterior of the plate, as shown in Fig. 7, or toward the interior, as shown in Fig. 8. v

Naturally, it is not necessary, that the apertures 5 should include, at the same time, the grooves 9 and shields 10 specified above. The apertures can include either the grooves 9 alone, as indicated in Fig. 5, or the shields 10 alone, as indicated in Fig. 6.

The columns shown in Figs. 3 and 4 are provided with plates having apertures rovided with grooves but without the shield. The scale of thedrawing does not permit of representing these grooves clearly on- Figs. 3 and 4, but they are of the same kind as those shown on a larger scale in Fig. 5 0f the drawing.

Having now particularly described and ascertained the nature of my said invention, and in what manner the same is to be performed, I declare that what I claim is 1. In a system of baflie plates for rectangular or cylindrical columns stills, a partition (3) having apertures (5) forming overflows, along the whole length of the periphery thereoi, the said apertures being uniformly distributed and placed at the same level, and having small grooves (9) starting from their base in order to facilitate the uniform distribution of the liquid. 4

2. In a system of baflle plates for rectangular or cylindrical columns stills, a partition (3) having apertures (5) forming over-- flows, alon the whole length of the periphery thereo ,the side apertures being uniformly distributed and placed at the same level and being provided with a shield (10) to prevent the passage of the vapors through the said apertures.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.

I I EMILE GUILLAUME.
