GAS-SCRUBBER.

SPECIFICATION forming part of Letters PatentNo. 237,542, dated February 8, 1881.

`Application filed July 3l, 1880. (No model.)

To all whom 'it may concern:

Be itknown4 that I, EDWARD JONES, a citzen of the United States, residing at South Boston, in the county of Suffolk and State of Massachusetts, have invented new and useful Improvements in Gas-Scrubbers, of which the following is a specification.

This invention relates to improvements in gasscrubbers for the purpose of condensing the heavy hydrocarbon vapors carried over with the gas, and especially for the purpose of separating and extracting ammonia and other deleterious compounds from the gas; and this I accomplish in the manner and by the means as will hereinafter be more fully shown and described, reference being had to the accompanying drawings, on which- Figure l represents a plan View of my improved scrubber. Fig. 2 represents a longitudinal section on the line A B shown in Fig. 1. Fig. 3 represents avertical section on the line C D shown in Fig. 2, and Fig. 4 represents a cross-section on the line E F shownin Fig. 2. y

Similar letters refer to similar parts wherever they occur on the different parts of the drawings.

rIhe apparatus consists of an outer casing, a, made of sheet-iron or cast metal, and an inner casing, b, madeof wood or other material. Between the casin'gs e and b is made a space or chamber, c, as shown, that contains gas, and serves as a non-conducting medium to prevent the heat of the surrounding atmosphere from being conducted to the inner casing, b.

b b represent beveled plank, to prevent the water from the T m entering the gas-chamber c.

The lower end of the inner casing, b, rests in the cup d, which isilled with tar or other liquid, c, that constitutes a liquid-seal at the bottom of the inner and outer casings, a b, and thus preventing the gas from escaping unwashed through the gas-space c.

On one side of the outer casing, a, is a conduit, f, through which the gas is forced downward from the inlet g, as shown by the arrows, until the lower water-receptacle, h, is reached, when it is deflected and conducted shelf it" is provided with a lip, Z l', that serves as a dam for containing a proper amount of water on said shelves.

l l represent rods or bolts passing through the shelves i i from top to bottom, as shown; and Z' l" l" represent pieces of tubing sur rounding the Vbolts l l between the shelves,

to keep the shelves in place.

At the top of the outer casing, a, is located a water-supply pipe, m, that extends within said casing as a perforated T, m', having perforations m on, through which a sheet or spray of water :is conducted downward upon the uppermost shelf, t', as shown, by which said shelf is filled with water to a dept-h equal to its lip or dam l, and by continuing the flow of water through the T-pipe m m each of the shelves i t" is tilled with water, that iiows from one shelf to the next one below in a spray or sheet over the respective lips or dams Z l', as shown. The upper edges of the said lips Z l are notched or serrated7 as shown in Fig. 8, and the notches or serrations of one lip are made to alternate with the corresponding notches or serrations of the succeeding lip above and below, as shown, so as to bring the gas in a more intimate contact with the streams or sprays of water flowing over the said lips l L' during the upward flow of the gas, as shown by the arrows. Before the gas is allowed to escape through the upper outlet, n, it has to pass through strips of cotton cloth o o or other porous, textile, or absorbent materials, the upper part of which is fastened to the board or rod p, and having its lower part dipping into the liquidretained on the upper shelf, as shown, by which arrangement the said strips'o o' are continually charged by capillary attraction with fresh water, through `which the gas is passed previous to going out through the outlet n.

At the bottom of the casing a, is the receptacle h, in open communication with the con Ioo duit f and the inner casing, b, as shown, into which the surplus Water and condensed matters How from the said inner casing, and are conducted away through the overiiow-pipe g, as shown. v

The shelves z' t" may be made plane or corrugated. In the latter case they may be used for a dry scrubber, it' desired.

The operation is as follows: The gas is conducted from theinlet-pipeg downward through the conduitf to the lower receptacle, 7L, and in so passing it comes in contact with the casing a, that is kept cool by the gas-chamber c and the running water within the scrubber b, causing all of the ammonia and a portion of the other impurities to be condensed and conveyed to the lower receptacle, h. The gas is afterward conducted upward through the sprays or sheets of water that run over the lips Z l and also over the water contained on the shelves i t" t' i', thus causing the gas to he brought in close and intimate contact with a large body of fresh water running in direct opposition to the flow of the gas, by which the object sought to be attained is accomplished in a quick and effective manner.

What I wish to secure by Letters Patent7 and claim, is'- 1. The herein-described gas-scrubber, consisting of the outer casing, a a, the inner casing, I), forming non-conducting chambers c, in combination with shelves 't' i', having serrated lips Z l', the conduitf, liquid cup seal d, and water-supply pipe m m m, as and for the purpose set forth.

2. In combination with the outer casing, a, and inner casing b, with its shelves, as described, the porous absorbent sheet or fibers o o', secured to the board or rod p, as and for the purpose set forth.

3. In combination with the outer casing, a a, the inner casing, b, with its alternate shelves, having serrated edges or lips l Z', non-conducting chamber c, the conduitj', inlet g, outlet n, lower receptacle, h, and overiiow-pipe q, as and for the purpose set forth.

In testimony whereof I have hereunto affixed my name in the presence of two witnesses.

EDWARD JONES.
