`Specification of Letters Patent. I

Patented Aug. 1, 1911.

application ated my 22, isos. serial No. 509,071.

' To all whom it may concern: l

Be it known that I, FRANZ KYLL, a citizen -of the Empire of Germany, residing at Co- '\logne'onthefRhine, in the Empire of Gr'er-v vrows of superposed balls, Fig. 3 is a horizon.-

many, have invented a new and useful Rectifying-Column, of which .the following is a specification. f

. My invention consists in improvements in rectifying-columns of the kind in which the drip plates are arranged to carry balls on speciall constructed vertical tubes, .whereby a ve'ry this division of the -downwardly flowing slnglings is obtained.

The chief improvement consists in new drip plates which are capable ofsupporting 'the balls and can bea comparative y easily cleaned. Each drip plate has ribs of either an undulated or a serrate cross sectionk, which ribs are provided `with su'ciently 1111-' merous and large openings lfor the passage of the rising vapors,.while between them holes are disposed for the singiings, their area being reduced by the insertion of needles or wires. 'The singlings .running down the endent needles or wires will necessarily be diivided into a drizzlin rain.

n Other improvements W1 Vbe hereinafter explained and pointed out in the claims.

I will now roceed to describemy inven-4 tion with -re erence to the accompanying drawings, in which- 'Y Figure 1 is a vertical section through an improved rectifying-.column without a still, Fi .l2 is a part out of Fig. 1 on an enlarged sce and 'shows one drip plate with two tal cross sectlonthrough the rectifying-columnbetween any two of its drip plates, the balls being removed,Fig. 4 is a vertical section' through a part of the rectifying-column in a plane at right an les tothat of Fig. 2, Fig. 5 is a part out of ig. 2 on a magnified scale and showsa needle inserted in ahole and supported byits head, Fig. 6 is a vertical section in a plane at right angles to that of Fig. 5 and shpws twoneedles, Figs. 7 and 8 are similar to Figs. 5 and 6 respectively, the only dierence lbeing that the smgle needles are replaced by needles secured in a supportingrod, Figs.v 9 and k1Q are similar to4 .Figs.'7 and 8 res ectively, the rod with the needles being rep aced by a repeatedly bent wire,the Vertical doubled parts of which are inserted in the holes, Fig. 11 shows a modified drip plate, and Fig. 12 is avertical central cross section through the same.

Similar characters of reference refer to similar parts' throughout .the several views.

The rectifying-column illustrated at Figs. l1 to 4 consists of a closed bottom section l, several intermediate sections 2, 2, a covered top'section 3, and several drip plates 4, 4 between the several sections, all these parts being bolted together. Each drip plate 4 has' several (here eight) parallel hollow ribs, so that its cross section is undulated, as is shown at Fig. 2. The cavity. of each rib 5 extends from a partition at one end to another partition at the other end of the rib.

1The furrows formed between the ribs are at the ends partly closed by partitions 6, 6 which extend upward to a certain height as shown at Fig. 4. Thus open channels 7, 7 are formed, which are separated from the annular channel 8 along the inside of the section 2 by the said partitions 6, 6. In each channel 7 the drip plate 4 is provided with a series of holes 9, 9, through which needles 10, 10 are introduced. These needles 10, 10 may be provided with heads 11, 11 (Figs. 5 and 6), by which they are supported. The heads are shown to have spiral grooves, as they are assumed to be formed from wire spirally wound around the upper ends of the shafts and afterward worked off. However, these spiral rooves are immaterial to m invention. rlghe needles 10, 10 reduce the area of the holes 9, 9, so that very small passages 33, 33 are left for the sin lings (Fig. 6). This is to be explained by t e fact, that the upper edge of the hole 9 is not in a horizontal plane, but in the curved surface of the furrow, so that the'spherical head of any needle 10 can come in contact with the edge of the hole 9 only in two opposite points (see Fig. 5) and consequently twol crescentshaped areas will be left between the edge of the hole 9 and the surface of the head. In the' walls of the ribs 5, 5 are large openings 12,12, which extend down to the height of the partitions 6, 6 or-nearly so and permit the rising vapors to pass through the drip plate 4 upward. Where so preferred, a heating serpentine tube 13-may be secured in'each section 2 at such a height above the drip plate 4, that its several turns passing between theribs 5, 5 remain clear of the surfaces of the latter. Without the section 2 the serpentine 'tube- 13 is connected with tubes 14, 15, which in turn by collecting tubes (not shown) are connected with some source of heating fluid. Balls 16, 17 are placed on the drip plate 4 ina manner clearly shown. Packing rings 23, 23 are in sertedl between the flanges of the sections 2, 2 and the end sections 1 and 3, and the several drip plates 4, 4 for tightening the apparatus. The bottom section 1 by its connection 18 maybe connected with some source of vapor, or it maybe replaced by the respective chamber of the ordinary still. The top section 3 is provided with a connection 19, through which the singlings from any known source are admitted to the rectifying-column, while the other connection 20 of the section 3 serves as an outlet for the rectified vapors which are'then further treated in any known manner.

During the operation of the rectifyingcolumn the vapors entering it through the connection 18 (or direct from the still, as the case may be) pass upward consecutively through the several drip plates 4, 4

until they in their rectified state escape through the connection 20, while the singlings entering the apparatus through the connection 19 flow into the annular channel 8 in the uppermost chamber, where they iow over the partitions 6, 6 into the parallel channels 7, 7 whence they flow through the narrow passages 33, 33 around the needles 10, 10 and along the latter into the next lower chamber, where they fall on the balls 16, 16, 17. Thus they successively pass downward through the holes 9, 9 in the several drip plates 4, 4 and through the connection 21 of the bottom section 1 (or direct) into the still, as usual. Should some of the needles 10, 10 get jammed, it will be suiicient to turn on steam from some source into the bottom section 1 through a nozzle 22 or the like; then the steam will push all the needles 10, 10 upward against the ser- - pentine tubes 13, 13, in other words move and thereby loosen them. Any dirt, such as grains of sand, or impurities or the like, that may happen to be deposited on the inside of the column, will be collected by the respective annular channel 8 and prevented by the partitions 6, 6 from getting into the channels 7, 7 and blocking up the holes 9, 9.

The needles 10, 10 not only reduce the area of the holes 9, 9, but also facilitate the down'- ward run of the singlings in thin layers and enable them to fall in a rapid succession in very small vdrops so that the singlings go downward in a drizzling rain.

Where so preferred, some heating fluid, for example superheated steam, may be passed through the several serpentine tubes 13, 13 for preventing the rising vapors from any or premature condensation, which latter according to experience takes place during the passage of the vapors through the openings 12, 12 in the' several drip plates 4, 4.

It is an advantage of the new drip plates 4,4, that the turns of the serpentine tubes 13, 13 can be placed between their . hollow ribs 5, 5 and thus brought 'r'nto close proximity to the openings 12, 12 for preventmg any undesired condensation of the vapors.

However the heating serpentine tubes 13,13

may be dis nsed wlth, 1f so desired.

The nee es 10, 10 in every channel 7 may be rigidly vconnectedy with one another by means of a horizontal rod 24 (Figs. 7 and 8), to which they are attached. Of course the rod 24 requires to be so shaped as not to completely close the areas in the holes 9, 9 around the needles, see Fig. 7. Or the rod 24 with theneedles 10, 10 may be replaced by a wire so repeatedly bent as to form several doubled vertical parts 25, 25

and several connecting horizontal-parts 26,

26, as is shown at Figs. 9 and 10.

The drip plates may be modified in the manner shown at Figs. 11 and 12, in which case their hollow ribs 27, 27 are made rectangular in cross section and are provided in their tops with openin 28, 28 and in their side walls with open1ngs-29, 29. Between the high ribs 27, 27 low undulated ribs30, 30 with holes 31, 31 in their tops for the `needles 10, 10 (or parts 25, 25) are provided on the drip late 32, so that in a similar manner as be ore any impurity, which may fall on the plate 32, is prevented from blocking up the holes 31, 31.

The total area of the openings 12, 12 in the drip plates 4, 4 or of the openings 28, 29, 28, 29 in the drip plates 32 is preferably made as large as possible so as to facilitate the ascension of the vapors.
