To all whom it may concern:

Be it known that I, DONALD BARNS MORISON, a subject of the King'of Great Britain and Ireland, residing at Hartlcpoohin the county of Durham, England, have invented Improvements in Apparatus for Separating Oil and Water From Steam Before it is Condensed, of which the following is a specification.

This invention relates to apparatus for separating oil and water from steam before it is condensed, and particularly to steam cleansing and condensing apparatus with steam winches, steering engines, steam pumps and other auxiliary engines in which oil is freely used and where such oil if it should pass into the boilers with the feed water, will be a source of danger by causing overheatingof furnaces, and will decrease the efliciency of the heating surfaces In such apparatus the cleansing and condensing of the steam may advantageously be effected in one combined structure in order to obtain high efficiency of cleansing and condensing, a minimum of weight, and the occupation'of a' minimum of space, which, on shipboard, are features of great importance. Such a compound apparatus may conveniently comprise a vessel or casing constructed with compartments or chambers that are in communication with each other in such a manner that steam admitted to the first chamber can flow-through the succeeding chamber or chambers in such a manner as to sweep practically through.

every part of the chambers, the first chamber or the first and one or more succeeding chambers being provided with devices that are arranged to ofier alarge surface to the steam flowing chambers and are adapted to distribute such steam throughout the width and length of the chamber or chambers and to separate and collect oil. and water an oil and water collecting receptacle, and the delivery end of the chamber or of the last cleansing chamber, with the condensing portion an opening or openings that cally throughout the length extends orextend practiof the condenser between thetube plates so that a practically uniform flow of cleansed and dry steam will take place from the cleans ing portion of the apparatus to the condensing or .heating portion thereof.

My invention may be applied to various types of surface and direct contact condensers. By way of example, I will describe it in connection with surface condensers such as those used on steam ships for condensing the steam from auxiliary steam engines and usuall termed winch or auxiliary condensers.

In the accompanying illustrative drawings, Figure l l is a transverse section, and Fig. 2 a plan partly in horizontal section-0n 'the line A A and partly on the line through the chamber or being in communicationof the apparatus through B B of Fig. 1, showing one constructionof combined cleansing and condensing apparatus according to this i invention. Fig. 3 is a vertical section, corresponding i to the line C C of Fig. 1, but to a larger scale, showing some of the steam distributing and oil and water sepaf' rating and collecting devices. Figs. 4 and *5 are sectional detail views showing modifications. Fig. 6 is a perspective view showing a modified arrangement of the apparatus. Fig. 7 shows partly in vertical section and partly in front elevation, Fig. 8 partly in plan and partly in horizontal section, and Figs. 9 and 10 in cross section on the lines E E and F F respectively of Fig. 7, one construction of steam cleansing apparatus according to this invention for use separately'fiom a condenser.

Referring to Figs. 1, 2 and 3, along one side, front side, and extending practically the whole length and depth of the casing l of the apparatus is formed a chamber 2 (hereinafter called for distinction the cleansing chamber) which contains the steam distributing and oil and water separating and collecting devices, hereinafter described, and is provided with a steam inlet 3, the front of the chamber 2 being provided with a removable cover I 4 which enables the interior of the chamber to be easily and quickly inspected and cleaned. The steam distributing and oil andv water separating and collecting devices are arranged so that oil and water separated from the steam flowing through the cleansing chamber 2 can drain into a receptacle 5 at the bottom of the chamber through suitable passages 6 in the cover 4. 7 is a communicating passage between the cleansing 2 and the next adjacent chamber chamber 8 of the condensing portion of the apparatus, the said passage eirtending practically the entire length of the cleansing chamber, and therefore the entire length of the condenser tubes 9, thereby maintaining a uniform velocity of flow from the cleansing chamber and facilitating uniform deposition of oil and water on the various surfaces in avoiding the creation of eddies and the disturbing influences of locally increased velocities, and also increasing the efficiency of the condensing surfaces by insuring a uniform' flow of steam over such surfaces. This uniform flow of the steam through cleansing chamber, particularlyfi'om the said chamber is a feature of considerable practical value, as it avoids any local discharge of steam from theehamber which would cause a disturbance of flow that would tend to sweep away any fine globules of oil and water which would otherwise be deposited, and also to pick up particles of oil and water that had been deposited and carry them off, and thus interfere with the efiiciency of the apparatus. The condenser in the example of apparatus shown, is of the multiple compartment type say the and from the having condensing tubes 9 through arrangement may be used.

- be divided up into a number of streams.

I and water that may be separated in the gupon lugs 10 onthe plates.

The oil and water separating devices comprise, as shown more clearly in Fig. 3, vertical plates 10 carried by the plates or diaphragms l3 and-against the opposite sides 0i which steam flowing through the guide slots 12 in the plates or diaphragms 13 is caused to impinge at such an angle as will facilitate the deposition thereon of oil and water from the steam without causing any undue back pressure or resistance to flow oi the steam. The oil and water collecting devices comprise horizontal or slightly inclined liquid collecting troughs or channels 11 supported at the lower ends of the plates 10. Each diaphragm 13 is in the form of a portable tray supported, like a shelf, in a slightly inclined posithe sides of the cleansing chamber tion, upon ledges at 2 so that, on the removal of the cover 4, the diaphragms with separating and collecting devices 10-11 can be 1 easily withdrawn and cleaned. The top of each diaphragrn is formed with transverse oil and water collecting channels 16 that drain into a longitudinal 'channel 16 (Fig. 1) which is in communication through passages 16 in the cover '4 with the drain passages 6, so that oil channels 16 can readily, drain through the passages mentionedinto the receptacle 5. The guide slots 12 are iormed'm downward extensions 13" of the diaphragm 13 and are so inclined to the plates lll that from such plates clear of the troughs 11 below, so that such troughs will not offer any. serious obstruction to the flow oi the steam through the The troughs 11 are of Y shape cleansing chamber 2. and are made separate from the vertical plates 10 from which they are supported by engaginghook-like supports 11 at their ends The lower ends of each set oi troughs 11 are arranged to discharge into a gutter 15 that'iis carried by the inner side of the cover 4 andis in communication through holesfli in the cover with the drain passages 6 so that the separated oil and water can drain from the troughs into the receptacle 5. The number of steam distributing diaphragms 13 and sets of liquid.separatingand collecting devices 10.11 used therewith, will depend on the amount of oil in the steam and the degree. of extraction thereof desired.

Steam distributing-and oil and water separating and collecting-devices of the kind hereinbefore described can be, constructed in various forms. Thus, in Fig.

spending Tdiaphragm 13, .and' the metal around such 'slots lis-extended upward to form

channels

16, 16 in of the diaphragm. .lilso, each liquid the 1 upper side collecting trough'll is formed in one piece with the "corresponding supporting plate 10,'the two portions ofeach trough atopposite sides of the plate, being connected together:

' InFig. 5, each o the steam fiowing through' them and impinging upon the plates will be deflected formed singly in the corre-v faces of the two plates and deposit oil and water thcreon. The collecting troughs for the oil and water separated by the separating deviccs ll) arc, in this case, formed by the collecting channels 16 in the top of the diaphragm 13 below such separating tend into such channels as shown.

Fig. 6 is a perspective view showing combined steam cleansing and condensing apparatus somewhat like that illustrated in Figs. 1 and 2, but wherein the water inlet and outlct branches l9 and 20 respectively are arranged at the top of the apparatus instead of at orposite ends thereof as in Figs. 1 and 2.

Steam cleansing apparatus with steam distributing the kind hercinbcfore described may also be construct-- ed separately from a condenser. Figs. 7 to 10 inclusive show one arrangement of this kind. The exhaust steam, containing oil, enters the wedge shaped distributing chamber 3 by the inlet 3 and flows into the cleansing chamber 2 through the guide slots 12 in the diaphragms 13 and over the separating and collecting devices 10 and 11 which are constructed and arranged substantially as in Figs. 1, 2 and 3, the separated oil and water passing through the drain passages 6 into the receptacle 5, and the cleansed steam flowing from the cleansing chamber 2 through openings 7 extending practically the entire length of the chamber into a jacket or passage outlet chamber 22 and thcnco to the cleansed steam outlet 22. The construction of the steam inlet cham- 21 and a wedge shaped ber 3 of gradually decreasing cross sectional area in an inward direction from the steam inlet 3, and theconstruction of the steam outlet chamber 22 of grad ually increasing cross sectional area in a direction towards the steam outlet 22,

particularly the latter- ,construction, is a feature of great practical value as it 1 allows of a uniform flow of steam through and from the cleansing chamber 2 as and for the purpose hereinbefore described.
