i APPARATUS FCR WASHING GASES.

Application filed January 8,

To all whom 'it may concern:

Be it known that I, JOHN ARMSTRONG. a subject of the King of GreatBritain, resid ing at London, in the vKingdom of England, have invented certain new and useful Improvements in Apparatus for Washing -Ga-SeS, of which the following is a specification.

The object of this invention is ratus for extracting from fumes or gases,

benzol, oil, acids, alkalis, oxids, carbonates, or other salts of metals or earths and other impurities, and for cleansing and scrubbing the gas or air from impurities.

he gases or fumes fortreatment are drawn ofi'` Afrom the delivery pipe, and passed under pressure in any Well known manner and are forced through the apparatus herein described. Referring to the drawings,

of the Fig. a vertical longitudinal section ratus; Fig. 3 a vertical section form of nozzle; Fig. 4 an end view thereof; iigs. 5 and 6 are vertical longitudinal sections also of the apparatus where only single tanks are used without the inverted tank, and Fig. 7 is a sectional view, taken on the line 7`7 of Fig. 2, showing the detail of the nozzle. y

Similar letters of reference apply to each.y

Referring first to Figs. l and 2, in these are a series of compartments formed and its diaphragms larger tank B, and around and through the an appa- Figure l is of my appaof a modified This tank rests in a as openings K all partitions.

Referring to Fig. 5, A A A are a series of `separate tanks joined by tubes conveying the gas or air to be cleaned or scrubbed.

Referring to Fig. 6, A A A are a series of compartments formed in' a tank of which the diaphragms M are the divisions, and C are the lids. These tanks are filled with the liquid to say the line shown at N.

is a pipe bringing the compressed gas or fumes to the nozzle F. Surrounding this nozzle is a larger conical tube E continuing with a parallel or nearly parallel continuation beyond the end of the tube F. This pipe H has three or more ribs R extending the length of the nozzle F, and forming a hole as shown in Fig. 7.

he two can be brazed together if desired.

The tube E is rifled by means of small flanges or projections S so as to cause a strong vor- Specicaton of Letters Patent.

tex, and there being considerable pressure on the pipe H and the nozzle F, the liquid and gases or fumes are intimately mixed and driven with great force forward into the tank. There is a line of these pipes Hand nozzles as shown in Fig. l, which gives a section however' of the middle compartment, and not the first compartment. In this first compartment there is a tube X, dipping down into the water, and a spindle with a handle at the upper end and an eye at the lower one connected to an elbow lever Y, the lower arm of zle, as clearly7 shown in Fig. 2. By moving the handle up and down it will be seen that the needle or scraper can be agitated in the nozzle F, and thus keep the nozzle open. In this compartment are a series of pipes D bringing the fumes from the top of the first into a nozzle and tube in the second chamber, while a. further funnel tube D carries them to the third chamsmany chambers as are G is the exit pipe for gases. The openings K, Fig. 2. are used when the-same Huid is used in all compartments or when only one tank is used with a single compartment, but where one iiuid for instance tar is used to condense and separate tar from the gas, and another Hui d say sulfuric acid for separating the amnionia, and another fluid say oil for separating benzol, and another fluid say lime water for separating carbonio acid the openings K are done away with and the apparatus as shown in Figs. 5 and 6 are used with separate ind ependent compartments.

eferring now to Figs. show a. section of a modilied lirst compartment, a similar in each of the other two or more compartments, the pipe H being curved and passed through the diaphragm M as shown in dotted lines instead of passing upwardly to the top of the tank, as shown in Fig. 2. In these, Q, is an open nozzle screwed into nozzle F An end view of nozzle Q is shown in Fig. 4. F is a nozzle continuation of tube D. latter is continued upward and ends in' a funnel as shown in Fig. 2. E is a modified form of funnel E.

In thus describing my invention, it is almost immaterial whether the nozzles F and the tubes E are horizontal, inclined or vertical, so long as they are concentric. Fur` 3 and 4 which inJector for the devlce is used o used `tor, extracting ammonia. and tar i through which ther, the tubes D with the nozzles, et cetera, are preferably tixed as in and 6, or as in the lid C olf tank shown in Fig. 5, for convenience ot cleaning, so that the entire inverted tank C with all its appurtenances can be lifted out of the simple tank l. Means for drawing o the water or other liuids, Vor dirt, in the tank, not shown, can bey placed in any convenient position. These form no and therefore l have not `depicted them, and they may differ in position in almost every installation. When too this apparatus is Jfrom gases, it may be desirable to give means for heating the saine but any well known means can be used for this purpose. A coil. heater for this purpose is shown in l? ig. 5, being designated by the letter W. When treating ordinary coal gas from the retorts, the tar and solid impurities are lett lioating mainly inthe first compartment. In the second compartment the gases can be treated Jfor ammonia, and in the third, oil can be place for extracting the benzol and other hydrocaibons.

l declare that what l claim is 2-4- l. In an apparatus for removing liquid or solid matters from air or gases, the combination of a tank adapted to contain a cleansing liquid; an injector nozzle immersed to a considerable depth in said cleansing liquid; means for forcing the air or gas to be cleaned at some pressure through the nozzle; and a tube surrounding the nozzle and spaced therefrom, whereby `an opening is formed in the rear ot the nozzle into and a strong current of liquid is drawn, and the entire power used for cleaning the air or gas is its own initial pressure.

"2. In an apparatus tor removingliquid or solid. matter lfrom air or gases, the Vcombination ot a tank adapted to contain a cleansing liquid; a horizontally-disposed nozzle placed at a considerable distance below the level ot the cleansing liquid and through which the air or gas is designed to be forced under pressure; and a tube surrounding the nozzle, the interior of said tube being ried at the forward end thereof, whereby a combined jet of the cleansing liquid and the air 0r gas to be cleaned is 'forced forwardly through the liquid in the tank with a rotary motion.

the tank C Figs@v part of my invention,

3. In an apparatus 'for removing liquid or solid matter from air or gases, the combinaf tion of a closed tank having partitions therein, forming a plurality of compartments, s

andadapted to contain a cleansing liquid; a series or' nozzles located in one ot' said compartments and placed at a considerable distance below the level of the liquid therein; an injector tube placed about each nozzle in spaced relation thereto, the interior discharge end oit said tube being rifled;l and means for removing air or gas from the upper portionof each compartment and delivering the same arranged in the next compartment.V

4. In an apparatus for removing liquid or solid'mattcr from air or gases, the combination of a tank open at its top; and an 'inverted tank a little less in area than the other located within the first tank and subdivided into a series of compartments by cross-partitions l0r diaphragms, the walls of said inverted tank and said diaphragms being provided with openings, whereby the various compartments are placed in intercommunication.

5. 1n anapparatus Jfor removing liquid or solid matter from air or gases, the combination otv a main tank open at the top; an inverted tank located in the main tank and provided with a series of cross diaphragns subdividing the inverted tank into a series of compartments; a series of pipes extendinA itrom the upper part ot each compartment downwardly and thence through a diaphragm and terminating in the lower portiongot the next adjacent compartment; a nozzle Jformed' at the lower end of each o said pipes; and an injector tube surrounding cachot said nozzles, whereby the air or gas will be' forced through the cleansing liquid in each of the compartments at substantially the same initial pressure paratus.

In wit-ness whereof, l have hereunto signed my name this 28 day ot December 1912, in the presence of two subscribing wit- HGSSQS.
