' APPARATUS FOR WASHIN AND cooLme GAS.
Be it known that I, HENRY L. DOiiERTY, a citizen of the United States, and a resident of Madison, in the county of Dane and State of. Wisconsin, have. invented certain new and useful Improvements in Ap aratus for Washing and Cooling Gas, of which the following is a specification, reference being had .to the drawing accompanying and forming part of the same.
My invention relates to apparatus for washing and cooling gas, and has for its object to rovide an apparatus for this purpose which s all perform its functions ra idly and effectively, with minimum loss the en- 7 riching constituents of-the gas'by condensation. The';inv'ention, which consists of the novel. features, arrangements of parts, and combinations of elements here nafter described, and more particularly pointed out in the claims, is shown in its preferred-embodiment in the accompanying drawings, in which Figure'l is a perspective v1ew ofthe appar'atus, with a portion of the walls Ibroken' away to show the interior construction and I 'broken away, showing the arran ement of- 3.9-
arrangement,- Fig. 2 is a pers ective view' of the casing, with portions 'of t e side Walls the compartments .and chambers t erein and their communication with each other. i Fig.'

'The outer casing of the apparatus may be any convement form, though Preferably the drawing the asin is designated by 1. It is divided into esired number of chambers by longituor both.. In the present embodiment there are eight chambers,A, B, C, D, etc., formed by a longitudinal wall or partition 2 and transverse partitions 3 to 8 inclusive. Each chamber 1' contains a mass of material of any suitable character having numerous-interstices or passages therein, so as to cause a liquiddischarged thereon to be spread'over a large. surface in flowing down through the mass.
however, to employ a number of I prefer, 4 layers or tiers of. flat-plates arran ed as follows, it being understood that eac chamber is similarly provided. A

around the inside ofthe chamber or across opposite sides thereof. Restin on their e ges on the flanges of those ang e-irons is a series of plates,10, of wood, iron, earthen ware,- or other suitable material. On these plates, extending at right'angles thereto as brought into contact with all parts of a stream of gas passing through the chamber.
Near the top the chambers are hermetically closed by horizontal partitions 11, providin aniiplper compartment above each cham er. the compartment are cooling ,pipes 12, coiled or otherwise disposed to provide a maximum length of pipe in each.
In the a paratus illustratedthe pipes in parallel lengt s connected in pairs by bends as shown, and the liquid, entering at the middle, flows back and forth across the compartment'toward the sides of the same. At A diagonally opposite corners the pipes pass throughv charge upon perforated trays 13, -b which the liquid is'deliv'ered evenly upon t e edge- 'w ise plates, which as before stated, constitute means for dividing the liquid into numerous streams and distributing it over a lar e area, r
n the bottom of each chamber isarran ed a series of bafile plates, as shown in chain er H, consisting of three horizontal plates 14,
spaced apart, and two horizontal plates 15 located above the spaces between those below. I The liquid falling from the distributer' strikes the baflie plates and flows gently oil of thelatter to the bottom of the chamber,
thereby avoidingany violent agitation of the liquid collected therein. I
' Theliquid in the bottom of chamber H can flow into chamber G by 'an arrangement as shown clearly in Fig.3. 16 is darn spaced 'slightlyfrom the partition 8, which'f latter is pierced by one or more apertures 17 The liquid rising. in chamber G will finally follows,
the horizontal partitions and dis-i leaves the apparatus through an escape pipe 18 from chamber H;
Extending from chambers B, C, D, E, F, G, near the bottom, are pipes, 19, connected with pumps (not shown), which are connected with the cooling pipes 12 above the same so that liquid may be pumped from the bottom of each chamber mentioned, delivered to the cooling pipe, and again discharged upon the distributer. The excess, over what is re-delivered to the distributer, flows out of the chamber to the one following, escaping finally from chamber H through pipe 18 as already explained.
The liquid in the pipes 12 may-hascoolei'l by radiation into the air, or the pipes maybeimmersed in a cooling liquid, as water. For this purpose the compartment above chamher A is provided with an inlet 20, by which the water may be introduced. From this compartment the Water flows into the next through an opening 21, thence to the next.
through an opening 22, and so on'through openings 23, 24, 25, 26, 27, and finally out of t e last compartment through the .outlet 28.
The openings'20 to 28' are located preferably at diagonally'opposite corners of the respective compartments, so as to better distribute the water and give it a longer flow over the cooling pipes. Y
A short distance below the closure 11 the partition 8 is provided with an opening, 29, similar openings, 30, 31, 32, are provided in, partitions 6, 5, and 3. Near the bottoms of partitions 4, 7, and in the longitudinal partition2 between chambers D and (E are openings 33, 34, 35.' In addition, chambers-H and A are provided with an inlet 36 and outlet 37, respectively, for the ingress and egress of the gas tobe washed and cooled.
From the foregoing the operation of the apparatus will be readily understood. The liquid, such as cold water, or ammoniacal liquor, etc., with which the gas is to be washed and cooled, is delivered through-the .cooling pipe in the compartment above chamber A, and being discharged onthe per- I forated tray below the chamber closure it is delivered" evenly upon the distributer and thence to the bottom of the chamber. Ac-
cumulating therein it overflows the dam,-

similar to that shown at 16, Fig. 3, into chamber,;B. From the latter it is pum ed through the outlet pipe (19) and delivered to the cooling pipe (12) in. the compartment above chamber B. There it is cooled by the water which is introducedinto' the first compartment and which is, as previously explained, flowingthrough the successive compartments. Collectin in the bottom of chamber B, a part of into C, whence a part of it is pumped to the cooling me in the com artment above and the liquid overflows gfinally c e'hvered upon 1; e distributer in the chamber; This process is repeated in each of the chambers, except; the last, and fr om that the liqu d'escapes through the 'ipe 18. At the same time, the gas to be scrub ed and .cooled is'admitted to chamber H throughthe inlet 36.- Rising in the chamber it passes through the distri'buter, where itis brought into contact with the scrubbing and cooling liquid over a large surface, and finally escapes into chamber G through the opening 29. Flowing downward-in chamber G it passes through another. di'stri'buter-and receives another washing and loses still moreof its heat. 7 This rocess is kept'up, the gas flowing ,alterna'tey upyand down until,
reaching chamber A, it flows out through the I pipe'37.
It will be evident that thewashing and cooling liquid has the highest temperature in compartment H, where the hot gas enters the apparatus; and that, the gas having lost some of its heat in the chamber just men tioned, the liqui'din chamber G is at a lower temperature. For the same-reason the temperature of the liquid in F is still lower, and so on through chambers E, D, C, B, and A,
in which latter it is coldest, being delivered thereto fresh. In this way the gas, after the apparatus has been in operation for afew minutes, at no time is subjected to a liquid at a temperature greatly below its own, and
it therefore never suffers a-sud den and viois that condensation of the volatile hydrocarbon in the gas ls'reduce'd to a minimum.
Moreover, the gas oil-entering, cont ainin as it does then the most impurities to be washed out, encounters the hottest 1i uid to do the scrubbing, 'andthe coolest an cleanest gas comes in contact with the coldest and fresh liquor. This gradual washing and cooling is of the-greatest importance, since it preserves the. maximumilluminating value of the gas as well as producing ammoniacal liquor .of the greatest strength. g
The baffleplates in'the bottoms of the chambers prevent agitation of the liquor therein, and'thetar is thereby allowed ..-t-o' settlean'd the light oil-y matter to rise to. the
The consequence;
surface. Thetar maybe drawn off from time bottom of the apparatus. The pipes 19'are preferably arranged to take the liquor from between the upper layer of light oily matter and the lower layer of tar, so that the liquor delivered to the cooling ipes is free as possible from such materials. f 'desired, fresh water or other washing liquid may be supplied to compartment B, and others as well, instead of pumping liquor from the bottoms thereof. Furthermore, the gas can be cooled to any desired degree scrubbed and thus freed from its impurities.
