GAS-CONDENSER.

To all whom t may concern.

Be it known that I, GEORGE E. IVooDs, a citizen of the United States, residing at New York city, in the county of New York and State of New York, have invented certain new and useful Improvements in Gas- Condensers, of which the following is a specification.

This invention relates to improvements in gas condensers for use in the manufacture of coal gas or coal and water gas.

In the manufacture of illuminating gas it is necessary to remove the impurities that would cause trouble to the consumer and in the manufacture of coal gas it is necessary to remove the tar, ammonia and such naphthalene as might cause trouble if passed through the .works or into the street mains.

One obj ect therefore of the present invention is to provide an improved apparatus for effecting the removal of deleterious or other substances without impairing the quality of the gas.

Another object of the invention is to provide a construct-ion of apparatus whereby the tarry vapors contained in the gas may Ybe manipulated and tend to eliminate the ynaphthalene and improve the quality of the gas.

A further object of the invention is to provide an improved construction of gas condenser whereby the gas may travel upwardly and be cooled by afluid traveling in a reverse direction or downwardly and thereby increase the efliciency of the condenser.

Another obj ect of the invention is to provide an apparatus whereby the gas may travel in an upward direction while -the tarry vapors may be separated therefrom and in descending through the up-owing gas collect therefrom other tarry vapors and naphthalene. Y y

A still further object is to provide an apparatusV whereby the tarry matters will be heated substantially tol a temperature equal to the temperature of the incoming gas and thereby have a greater aiinity for naphthalene because the hotter'the tar the greater is its Vaffinity. to hold the naphthalene, and further because thehigher the temperature of the tarry matter the latter is less liable to absorb illuminants from the gas.

Another object is to provide a construction whereby tar at a, proper temperature may be injected into the condenser at a point Specification of Letters Patent. Patented Aug. 15, 1911.

or points adjacent the gas inlet Aand outlet for the purpose of removing naphthalene and also for the purpose of liberating some of the benzols or other vapors contained in the tar and thereby increase the candle ower. l Y 4Vlith these and other objects in view the accompanying drawings illustrate one form of apparatus for carrying the invention into ,practical effect.

In the drawings, Figure 1, is an end ele.- vation of the apparatus, Fig. 2, a side elevation ofthe same, Fig. 3, an enlarged cross- Vsectional elevation of the lower and upper portions of the apparatus,the sect-ion being taken on the line 3 3 of Fig. 4. Fig. 4, an enlarged transverse sectional elevation of the same, and Fig. 5, a horizontal crosssection through one of the condenser sections,-the section being taken on the line 5 5 of Fig. 4.

Referring to thedrawings the numeral,

1, designates the base section of the condenser, which -may have any desired cross- ,sectional formation but which, in the present instance is of a rectangular shape.y This base section is provided with walls, 2, which extend vertically therefrom and which form a chamber, 3, into which the hot incoming gas enters through the inlet, 4, provided in one of the vertical walls..

vIn the present instance the base section is provided with a bottom, 5, Awhich has position in a plane below the gas inlet, 4, Aand preferably this bottom is inclined so that substances deposited thereon may flow or move toward a given point and be drained off in any suitable manner, as for example by means of a pipe, 6, or other means, and conveyed to a suitable receiver, not shown, In the present instance this bottom, 5, inclines downwardly towardthe wall containing the gas inlet opening, 4, and its lowermost end has position in a horizontal plane below and directly beneath said inlet whereby, to produce a dam-like formation for the accumulation of the tarry matters. It is at this particular lowermost point in the present form of structure that the outlet pipe, 6, is provided. l Y Y The condenser comprises an upper shell formed in the present instance of a plurality of sections, 7, and each section has a smooth outer surface and a downwardly-projecting flange, 8, at its lower inner edge which engages the upper -edge of the Vsection upon Vso which it rests, whereby to lock said adjoining sections together.Y The broader side-V condenser rises from the base it will taper-- or gradually become narrower for a purpose presently to be described.

If desired, at suitable intervals between the lower and-upper ends, the sec-tions of the condenser may be provided with suitable cross-bars or webs, 10, having perforations therein, also for a purpose presently to be explained.

The uppermost section, 11, of the condenser is provided with a gas outlet, 12, in one of its walls while at another wall a suitable pipe, 13, enterssaid section and in the present instance is provided with a perforated outlet or rose, 14, through which heated tar may be sprayed downwardly.

In order to securely lock the sections down one on top of another I provide suitable rods, 15, having their lower ends secured in any suitable manner to the base section, 1, and extending upwardly therefrom and through the perforations in the cross-bars or webs, 10. The upper ends of these rods are threaded and project through the perforations in the cross-bar of the top section, 11, and nuts are screwed onto said projecting ends. A coiled or spiral spring, 16, surrounds the upper end of each rod and is compressed between the nuts and the cross-bars ofv said upper section whereby to provide for the expansion and contraction of the respective sections during the heating and cooling thereof. In addition tothe rods, 15, on the interior of the condenser I may also provide exterior guy-rods, 17, which connect with suitable lugs, 18, on one of the sections to brace the condenser from the exterior.

A suitable cover or top plate, 19, is bolted or otherwise secured on the uppermost section, 11, for the obvious purpose of closing the condenser at that end.

The condensation is to be effected by the cooling action of the condenser walls on the heated gas passing upwardly therethrough, and the manner of cooling or lowering the temperature of those walls may vary, for example, a Ipipe, 20, is arranged about the uppermost section, 11, and is provided witha series of perforations, 21, which have position atV the side or adjacent the wall of the condenser. This pipe is designed to convey and spray water against the walls of the condenser, which by flowing down ythe taperedV walls will run over the said denser at the bottom and through the opening, 4, and then travels upwardly seeking the outlet opening, l2, in the uppermost section, 11. During the passage of the gas from the lower to the upper section of the condenser its temperature willrbe lowered, because of the air and water cooled walls thereof, and condensation will result. During the ascent of the gas the latter will be cooled which will cause the tarry vapors to descend and travel in the opposite direction from that in which the gas is flowing, and the latter will give up some of its tarry vapors and naphthalene content because of the aflinity of the tar for naphthalene. By means of this apparatus the tarry matters will run o and leave the condenser at the incoming temperature of the gas because the hotter the tar the greater is its aflinity for naphthalene, the tar will hold the naphthalene and not give it up to the gas. Moreover as the tarry matter is hot it will not absorb the illuminants from the gas.

During the operation tar of proper temof the condenser is greater than that of.

any condenser within my knowledge, attributable largely to the fact that the gas and tar travel in reverse directions, and the removal of the impurities in the gas, and particularly that of naphthalene is more thoroughly obtained. The result of these reverse flows also tending to increase the candle power, the absorbing power of the tar for benzols, etc.,y being reduced owing to the temperature at which the tar leaves the con-` denser.

Having thus described my inventionwhat I claim and desire to secure by Letters Patent is,- f

1. A condenser comprising a plurality of vertically tapered sections one on top of another and the lower one being larger than the one above it whereby to form an upright tapered shell with a continuous passage from the lower to the upper sections,-.

the lower largest section of saidV shell having a gas inlet and the uppermost smallest section having a gas outlet and rods extending through the interior of the sections for holding the tapered shell sections together..

2. A gas condenser comprising apluralit-y lower to the upper end,-the lowermostY section of the shell being providedwith an inclined bottom and having a gas inlet adjacent the said bottom and the uppermost section having a gas outlet, means extending through the interior of the shell-sections for holding the same together and means around the exterior tapered wall of the uppermost smaller section for directing water against the wall thereof.

3. A gas condenser comprising a plurality of tapering sections one above another,- the lowermost section having an inclined bottom, the upper section having a cover and the intermediate sections being open so as to form a continuous central chamber from the inclined bottom where it is widest to the cover at the upper end where it is smallest and the lower section having a gas inlet and the upper section having a gas outlet; rods extending from the inclined bottom of the lowermost and largest shell section through the intermediate sections to secure the same together and means adjacent the said inclined bottom of the lowermost largest section for drawing off deposits therefrom.

4. A gas condenser comprising a plurality of superposed sections each being larger at its lower end than at its upper end and the sections diminishing in size from the lowermost which is largest to the uppermost which is smallest and the largest and smallest sections each having an opening, a rod extending vertically through the interior of the sections from the bottom of the lowermost largest section, means in the uppermost smallest section for securing the upper end of said rod and means for directingl water against the wall of the uppermost smallest section. v

In testimony whereof I ailix my signature in presence of two witnesses.
