INVENTOR ATT'ORNEY June 23, 1931. o. H. ESCHHOLZ GAS EXCHANGE SYSTEM Filed Aug. 6, 1927 2 sheets-sheer 2 0770 /7. fsc/Ma/z Patented June 23, 1931 *UNITED STATES PATENT OFFICE OTTO H. ESCHHOLZ, OF 'WILKINSBUEG, PENNSYLVANIA, ASSIGNOB TO WESTINGHOUSE ELECTRIC & MANUFACTURING. COMFFANY, A CQRPCRATIOH OF PENNSYLVANIA GAS EXCHANGE SYSTEM Application filed August 6, 1327. Serial No. 211,080.
My invention relates to a method of and apparatus for controlling or effecting the transfer of a constituent of a gaseous medium to a liquid medium contacting therewith.
In accordance with my invention, an efi'ect is produced in one or both of contacting gaseous and liquid mediums to effect the transfer of a constituent of the gaseous mev dium to the liquid medium aside from or hi dependently of the heat generated by an electrical translating device immersed in the liquid medium.
Further in accordance with my invention, a liquid medium, as the oil in which a transformer or other electrical translating device is immersed, is treated independently of the heat generated by said translating device to accelerate the transfer to said liquid medium of a constituent of a contacting gaseous medium.
Further in accordance with my invention, the oil surrounding an electrical translating device is elevated in temperature independently of the heat generated thereby or is treated with a suitable agent, either catalytic or non-catalytic, preferably in a local region or zone only, to facilitate the passage of a constituent of the gaseous medium to the liquid medium.
Further in accordance with my invention, oxygen occupying the gas space of a casing containing an electrical translating device immersed in a liquid medium is transferred to the latter aside from or independently of the heat generated by said translating device.
My invention resides in the method, apparatus and system of the character hereinafter described and claimed.
For an understanding of my method and for an illustration of some of the forms my apparatus or system may take, reference is to be had to the accompanying drawings, in which, t
Figure 1 is a vertical, sectional view of apparatus constructed in accordance with my invention, 7
Fig. 2 is a transverse, horizontal, sectional view taken on the line 11-11 of Fig. 1 looking in the direction of the arrows.
Fig. 3 is a vertical, sectional view illustrating a modified form of my invention.
Fig. 4 is a transverse, horizontal, sectional view taken on the line IV-IV of Fig. 3 looking in the direction of the arrows.
Referring to Figs. 1 and 2, there is illustrated a casing or container 1 within which is disposed a liquid medium 2, as oil, surrounding and insulating an electrical translating device, herein illustrated as a transformer 3 having terminals 4, 4 passing, re spectively, through suitable bushings 5 carried by a cover member 6 bolted or otherwise suitably secured, to the casing 1.
Communicating with the casing 1 in a region below the level of the liquid medium 2 is a pipe or conduit 7 opening into a suitably dimensioned expansion tank or chamber 8 open to theatmosphere as indicated at 9 and mounted, in the example shown, on brackets 10 projecting from and carried by the casing 1.
Apparatus of the character just described is well known to the art. The liquid head in the conduit 7 and chamber 8 normally maintains the pressure of the gaseous medium in the space 11 slightly in excess of atmospheric pressure. Upon operation of the transformer 3, heat is generated and the liquid medium 2 expands, thereby placing the gaseous medium in the space 11 under increased pressure and effecting passage of some of the liquid medium 2 to the chamber 8 by wayof the conduit 7 Ordinarily, when the apparatus is initially placed in operation, oxygen-containing air occupies the space 11; during operation, more of such air may find its way into the space 11,
for example, by passing through a suitable dehydrator and then through the chamber 8 and conduit 7 when the oil within and without the casing 1 assumes substantially the same level. The presence of any large or substantial amount of oxygen in the space 11 mitigates against safe operation, for as is well understood, when the insulating medium 2 is of hydrocarbon oil, an arc in contact therewith may cause the evolution of hydrogen, methane and the like which pass into the space 11 and there combine with oxygen to form an explosive mixture.
In accordance with my invention, one or both of the aforesaid mediums is or are suitably treated to effect the passage or transfer to the liquid medium 2 of oxygen found in the gaseous medium occupying the space 11. As an example of an arrangement for accomplishing this end, there is illustrated abarrier or wall 12 which is preferably of heat.
insulating material and welded, or otherwise suitably secured, to the interior surface of casing 1. Wall 12 may be open at both ends and extend upwardly well above the maximum level of the insulating medium 2. Disposed within the compartment bounded by barrier 12 and casing 1 is a suitable heat generating device, herein illustrated as a resistance element 13 having its terminals connected by conductors 141, 1 1 to a source of electrical current, not shown. A resistance 15 interposed in the circuit comprising the conductors 14:, may be adjusted to control the magnitude of the current traversing said circuit and, consequently, the'amount of heat disseminated by the element 13.
Generation of heat by the resistance element 13 increases to a marked extent the temperature of the liquid medium disposedwithin the space bounded by the wall 12 and casing 1. As a result, oxygen isjabsorbed from the gaseous medium in'the space "11 at amuch higher rate than would occur if the liquid medium was raised in temperature solely by the heat generated by the translating device 3. Consequently, the gaseous medium in the space llis rendered inert, or substantially so, with respect to gases evolved from the hydrocarbon liquid medium 2. Thus, for example, in ordinary operation, the temperature of transformer oil is substantially 80 C. whereas, in accordance with my invention, the tem perature of the liquid medium in the com partment bounded by wall 12 and easing 1,
may be of the order of 120 6., more or less. At the high temperature last noted, oxygen is absorbed at high rate.
The absorption of oxygen by the aforesaid liquid medium is, in effect, an oxidizing'process and when the latter comprises hydrocarbon oil, di-basic or anic acids are formed, the latter being harm ess when no substantial amount of water 18 present. In the event that the hydrocarbon oil contains unsaturated hydrocarbons, asphaltic sludging compounds are formed by the aforesaid oxidizing action.
In either case, suitable materials may be introduced into the'spa ce bounded by wall 12 and casing 1 to absorb or dispose of the volatile and other products resulting from oxidation of the oil. Or, the lower part ofwall 12 may constitute a drain for removing the products of oxiaaa aana, if desired, the comformed by wall 12 and easing 1 may be entirely isolated norm the main space in which the transformer is disposed. Entry to this isolated compartment may be effected in any suitable manner, as by a passage extending through the casing 1, through which the products of oxidation may be removed and the supply of oil replenished.
Referring to Figs. 3 and 1', there is illusstrated a modified form of my invention, wherein aportion of the insulating medium 2 passes pipe or conduit 16, preferably enlarged as indicated at 17, to provide a chamber where.- in the heat generating device 13 is disposed. The upper end of conduit 16, Fig. 3, extends into the space 11 preferably above the maximum oil level and constitutes a stand pipe exposing a surface of hot oil to the gaseous medium in space 11. An arrangement constructedas illustrated in Figs. 3 and 4 open ates substantially as does the arrangement illustrated in Figs. 1 and 2. i
Some grades of transformer insulating oil when heated, absorb oxygen to greater extent than do others. Accordingly, with a construction such as illustrated in Figs. 1 aiid'2, in case the main insulating medium '2 comprises oil incapable of absorbing oxygen at high rate, there may be disposed within the compartment bounded by wall 12 and casing 1, a different grade of insulating oil capable of absorbing oxygen at a high rate when heated. Or, the aforesaid compartment may be entirely isolated from the main space in which the transformer 3 is disposed, and have disposed therein an oxygen-absorbing material of a character entirely different from the insulating medium 2.
It shall be understood that within the scope of my invention, in lieu of the application of heat to a liquid medium, a saforesai'(l, such medium may retain in suspension a suitable agent, either catalytic or non-catalytic, whereby oxygen or other gaseous component is absorbed from the gaseous medium in the space 11. For example, copper, iron or their oxides, preferably in finely divided roan, may be placed in the insulating liquid medium 2. Or, manganous soaps or resinates may be utilized in combination with or in lieu of the aforesaid copper or iron foriucreasing the oxygen absorbing quality of the insulating liquid medium.
It shall also be understood that the. gaseous medium in the space 11 may be suitably treated to facilitate thetransfer of a conthe ozonati'ng apparatus being operated, if desired, by the transformer 3.
' It shall be understood that arrangements structurally different from "that herein disclosed may be utilized. Thus, under some circumstances, it maybe desirable to omit the exteriorly of the casing 1 through a its tially higher than the main body of the liquid medium. This action is effected in a chamber or compartment in communication with the main casing and, therefore, the supply of liquid to be brought to high'temperature is constantly replenished even though evapora-.
tion thereof may occur at a fairly rapid rate, as induced, for example, by the resistance element 13, or equivalent.
In the appended claims, the term electrical translating device or translating device refers to the transformer 3, or equivalent, and not to the resistance element 13, or equivalent.
I- claim as my invention:
1. In the art of controlling interchange between a gaseous medium and a contacting liquid medium in which an electrical translating device is immersed, the step which consists in elevating the temperature of said liquid medium in a local region only inclependently of the heat generated by said translating device for transferring a constituent of said gaseous medium to said liquid medium.
