Hhallauhom it may eoncem:

lie it known that we, CnAnLEs llowann vi-Ftnvtnn and EnwAnn ARNOLD MEDLEY, subiects of thevliing of Great Britain, both residing at Great Crosby, Liverpool, in the county of -Lancaster, in the Kingdom of England, have invented certain new and useful Improvements in Apparatus for Subjecting Gas or Vapors to the Action 0t Liquids, of which the following is a specitication.

win our .llritish patent specification No. @2282 of 1902, Wt. described an apparatus tor subjecting gas to the action of a spray of i --'=Wa,ter. This apparatus consisted essentially .of a vertical cylindrical case, closed at the endsrwithin which revolved a vertical shat't to which were fixed two or more horizontal circular disks, of a diameter smaller than "l0rithe'internal diameter of the case, so that t-here was an annulars mce around each re nivolving disk. Between each pair of revolvr -.ing disks Was a stationary tray or dish, preterably conical in shape, the apex ot the cone -pointing downward, the outer diameter tilting closely to the case and the revolving shaft passing'throngh a. hole in the center of the" tray With ample clearance tor gas and water. to flow as hereimlfter described. l

pipe on to the :nppermost revolving disk near to its center, and revolving'With it was whirled otl trom I its circumference in a finely divided spray. This spray after dashing against the wall of l 5 the case fell on to the tray below and ran @down it toward the shaft, until reaching tithe hole in the center of the tray it tell *through on to the disk revolving beneatlul 'which again threw it elf as a spray at its l 40 circumference. And this process was repeated for as many disks and trays as the ,l apparatus contained, the Water descending] from disk to tray and from tray to disk until I it reached the bottom and left through a suitable trap. The gas followed the same path as the water but preferably in the opposite direction. Entering the apparatus at the bottom it passed through the annular space between the case and the lowestrevolving disk, meeting there the spray thrown oil by the disk, thence guided by the tray above the disk the gas traveled toward the shaft, passed through the hole in the middle of the tray and thence flowed to the annular space around 'the next revolving] the apparatus Specification of Letters Patent.

disks, where it was again subjected to. the water spray. And this process was repeated until the gas having passed all the disks left the apparatus by alsuitable discl'mrge pipe.

It is clear that this apparatus can be used with other liquids as well as with water and the present invention is for an improved. form of this apparatus by means of which the amountof s 'n'aying by water or other liquids to which the gas or vapor isle be subjected is greatly increased without much increasing the size of theapparatus. \Ve etlcct this by substituting for each single revolving disk :1 number of such disks, tixcd one above the other and separated from each other by a short space. And thus intead ot a single spray from the periphi ry of a. single disk we obtain a layer of sprays from the peripheries of a group of disks. Means must be employed for bringing to each of the several disks torming a group its proper supply of liquid. The drawings set. forth our latest designs tor this purpose.

Figure 1 shows a vertical section of our apparatus; Fig. 2, a plan view of the trays tor general purposes. while Fig. I) is a. section, and Fig. l a plan of a modified form of tray. V l

ltel crring first to l igs. l and 2, the bottom disk A of a group oi disks A, ll, (J, 1), 8o is lived to the vertical slla'l t t-l and the upper disks oi. the group ll, (3, l), are attached to the disk A. The upper disks ll, (l, I), have each one a central hole burger than that in the disk immediately beneath it, that is, the hole through the center of disk 1 is larger than the hole through the center of the disk (1, and the hole through the center of the disk is larger than the hole tln'ough the ccntcr ol the disk ll. Above each group of disks is tilted a conical tray T, the holein the middle of which .is so shaped that some of the liquid running down the. tray isdelivered on to each of the disks revolving below. Thus, referring to Fig. 2, which shows a plan of a tray and group of disks, the liquid running over the edge a, 7), of the hole a, b, e, (Z, it, g, f, e, in the middle of the tray falls through the holes in the centers of the disks B, 1G, I), on 105 the bottom disk/k. The liquid running t over the edge, 0 (1, falls on the disk B. The liquid running over the edge, e f, falls 011 the disk 0, and the liquid running over the edge,

g Ii, tails on the disk 1). Thus eachdisk 1 of the group of disks receives its proper proportion of the liquid running down the tray above the group, and it is clear that this method can be adopted for groups of disks consisting of a greater or less number than four.

The liquid can be delivered in a convenient manner over the. upper surface of the top tray T, by allowing it to fall from the su ply pipe P on to a single revolving disk After the liquid has been sprayed from the peripheries of the uppermost group of disks A, B, C, D, it falls on to the tray below,- which delivers it to the next group, and so on for as many groups of disks as the apparatus contains in exactly the same man ner as we described in, our specification No. 22282 of 1902. The liquid leaves the apparatus by the ipe Q, which can be suitably trapped, and i desirable the liquid can be raised by means of a pump to the supply pipe P, and again circulated through the appaiatusv The gas or vapor to be treated enters the apparatus by the pipe R, and

tray

leaves it by the pipe U.

1 ,Referring now to Figs. 3 and 4:-These show a form of fixed tray having an opening for the gas to pass through not merely at the center, but at the circumference also seas to allow of a shorter and freer passage for the gas through the machine; Also to insure even distri u'tion. of the liquid it is desirable; to divide from each other by means of radialribs the several sections of the tray 'which feedthe corresponding disks revolving below. These ribs or arms M alone connect the tray with the circumferential ring N which latter is firmly fixed to the cylindrioal. casing, so that there is a circular con- 'duit-for the passage of the gas around the edge L,while the s rayed liquid runs off the up er-suriface o the ring N and falls on to t is tray and thence is delivered on to therevolving disks. It is also desirable to so ethe perforation in the center of the t gat' each'revolving disk is fed with liquid'in two or more places diametrically opposite to each other. Thus in Fig. 4 the segments H H feed one disk, the segments a second, the segments J J a third and the 1 segments K K a fourth. The object of this double feed is to distribute the liquid more evenly over the disks than is the case when each disk isfed fromga single segment;

We declare that what we claim is 1. In apparatus for subjecting gas or vapor to the action of liquids, the combination of a closed ohainbena vertical shaft, a set of horizontal disks rigidly carried by said shaft, and fixed only a short distance from each other, and means for supplying each of the disks near the center with a substantially equal part of the liquid supplied and means for passing the gas to be treated through the i apparatus and past the peripheries of these disks.

22. In apparatus for subjecting gas or vapor to the action of liquids, the combination of a closed chamber, a vertical shaft, 3 disk fixed to said shaft, a feed pipe delive .on to said disk, whereby the feed is 3? tributed all around, a funnel for collectin the distributed feed, having a plurality 0 exit edges substantially evenly s aced rigidly around the center, and a p urality of disks below, carried by said shaft, each receiving the liquid from one of these exit edges and means for passing gas up past the edges of these disks.
