In the accompanying drawings, forming part hereof, Figure 1 is a longitudinal vex-ti cal sectional view of an apparatus embody- Fig. 2 is a'transverse' ver- Referring to the drawings, it will be ob, served that the outer stationary cylindrical: casing A is provided with a gas-inlet .opening a and a gas-outlet b. This casing is p110- yided upon the inner walls thereof with a wire-netting or other suitable coveringc, as

- is well understood, to present aniextensiye surface for theliquid. The lower portion-of,

the casing is submerged in aliquid contained 7 within trough-like containers D, into which extend partitions E, that do not reach-to the bottoms of said containers D, but extend up to the casing A and betweenthe openings dc therein. The opening d permits water or other liquid'within the'containerto pass into the casing, and it is then taken up and-flows out again through the opening '6, as will here; inafter more clearly appear. 5

\Vithin the casing A is contained a rotary cylinder B,',-which is provided on the exterior thereof with oblique or spiral blades as, by meansof which the wateror other absorbing liquid is being continually carriedaround have i'n vented new arid useful Improvements in Ap;

It

will, be observe'd that by my in veiition small "quantities'of liquids can be injected through titles of liquids can be readily volatilized by the heat of the gas, while larger quantities of KOO small quam q a 55 temporarily displaced to cool water can be conveyed through other of the nozzles h, &c.,-to condense the vapors, together with the materials they carry.

. "In operimon the hot gases to he pu rifled em 5 ter at a and pass lengthwise between the cylinder B and the casing A, being at the same time whirled by the blades as. The water or otherabsorbing liquid contained in the re--' ceptacles D and in the lower part of the easrc ing A is continuouslypicked up and carried over the cylinder B by the blades w from the opening/d on one side'ot the partition E and is thenco-hveyed back into said receptacle or containerthrough the opening e on the other :5 side of the partition. During this movement the water is thrown out against the netting or equivalent covering a, which atomizes the water-er breaks it up into minute particles,

' and thusgives the liquid a large surface, so thatit' can more readily absorb impurities contained inthe gas. These impurities are heldin suspension while the liquid is in violent motion; but upon the return of the liqfl u'id' to the receptacle D the impurities settle r atthe bottom ihereo-t and the clear liquid passes under the partition E to the-opening d.- ;The liquid or liquids supplied through thenozzles h" h -h are also throwin'outward and'ato'mized by centrifugal force and bythe 3o covering 0 and assistin purifying the ga s.

*Atthe same time the hot gases vaporizethe atomized liquid. For instance,small quan- .tities of a washing or. absorbing liquid may j be injected through the nozzles h h", so that the heat of thegases will be sufiicient to vaporize saidliquid, and then the gases as they ap roach the outlet b will be subjected 110112118 action-[of a; larger-amount 'ot cooling-water -i.-su'i ||gl'ro|n: the nozzles h, so as to-cause a condensation. of the apors formed from the liqu idea ogel her with the impurities absorbed by seid'vapors. Finally,-the liquid Will be thrown into the chamber'M', so that the cov- .eriug a will intervene between the-body of 5 liquidand llle gases, thus freeing the latter of liquid or drying them. The dried and purified gasestescapethrough-the outlet 1). v By reason of the fact thatthe openings in the casing A are sealed by the water conse tained within the containers D there is little liability of explosion taking place'in the treatment of the gases, as an undue pressure of gas will cause the gas to be driven through the water, seal or willcause the water to be permit the free escapeof surplusgss.

- By the horizontal disposition or the h ratus instead of, a vertical arrangementit has been found that the apparatus is'more eili 6o cient.

' Having described my invention, what I claim, and desire to secure by Letters Patent, H

1. In an apparatus for washing gases and removing impurities therefrom, the combination of ahorizontally-arranged stationary casing having liquid receiving and discharge openings therein, aliquid-container over which the casing rests, said casing and-container being so arranged with relation to each other that the mouths of'the openings in the former will be snbmergedin theliquid in the container, a rotary horizontally-arranged exteruallybladed cylinder contained within said casing for conveying liquid from the liquid-receiving opening in the casing to the discharge-opening therein and means carried by said cylinder forcontinually supplying to the apparatus a washing or absorbingliquid other than thattaken from the container.

2. .In an apparatus for washing gases and removing impurities therefrom, the combination of a horizontallyarranged casing having liquid receiving and discharge openings therein, a .liqnid-contaiuerover which the easing rests, said casing and container being so arranged with relation to each other that the.

:and means for supplying said chamber or chambers with liquid. 4

3. The combination of .a stationary casing with a rotary cylinder having obliquely-disposed exterior blades, means for causing gases to'pass between the casing and the cylinder, and means for spraying liquid in said space between the rotary cylinder and the stationary casing, to cause said liquid to pass out- ,wardlyfrom' the cylinder to the casing and to come in close contact with'the gases.

4. The combination of a stationary casing, a rotary cylinder located within the casing and provided with external oblique blades, means I LO for passingacurrent of gas between the casing and the cylinder, and spraying devices locatedat difierent points lengthwise of the cylinder for discharging a liquid into the space between the cylinder andthe casing, causing said liquid to be thrown outward against the casing and to pass through the current of gas.

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

EDWARD THEISEN.
