Y., assignor to Foster Wheeler Corporation, New York, N. Y., a corporation of New York Application November 22, 1939, Serial No. 305,632
14 Claims.
This invention relates to apparatus for the separation of fluids from mixture thereof, more particularly the separation of vapor and liquid from mixtures of the same. The invention will be disclosed as applied to the separation of steam and water in a drum of a water tube boiler, but it will be understood that the invention is not limited to this particular application, but it may be utilized generally in the separation of vapors and liquids from mixtures thereof.
In water tube boilers, mixtures of steam and Water rise in the heated tubes and discharge into drums wherein the steam separates from the water. The steam leaves the boiler through openings in the upper portion of the drum, and the water remaining in the drum, recirculates through the heated tubes wherein a further portion of the water is evaporated, and the separating process is repeated. In many steam boilers, particularly those which are operated at high specific rates of evaporation, the separation of water and steam is not complete, due to the fact that a portion of the water is carried off with the steam from the drum, and a portion of the steam iscarried back with the water to the boiler tubes. This incompleteness of separation is un desirable from the standpoint of the superheating equipment. and the steam consuming equipment.
The present invention overcomes this disadvantage and provides separating apparatus whereby steam and water or other vapors and fluids in admixture will be more completely separated in the steam drum or other enclosure.
The invention will be understood from the 01- lowing description when considered in connection with the accompanying drawing forming a part thereof, and in which:
Fig. l is a transverse vertical sectional view of a boiler steam and water drum embodying one form of the invention;
Fig. 2 is a top plan view of another form of centrifugal separating means which may be utilized;
Fig. 3 is a vertical sectional view of the separator shown in Fig. 2;
4 is a vertical sectional view of another form of separator, and
Fig. 5 is a top plan view of the separator shown in Fig. 4.
heated or steam generating tubes H, and a plurality of downcomer tubes l2. The drum is'provided with a steam outlet l3. The drum is separated into two compartments, A and B, by a diaphragm or partition l4 which extends longitudinally of the drum throughout its length. As shown, the diaphragm comprises an upper horizontal portion and a downwardly extending portion which engages the inner wall of the drum just upwardly of the outermost row of boiler tubes H. The diaphragm extends below the water level in the drum and separates the body of water entering the downcomer tubes I2 from the mixture of steam and water which enters the drum through the generating tubes H.
In the horizontal portion of the diaphragm are disposed a plurality of .short, tubular separating members l5 which are open at their upper ends and are closed at their lower ends, and have adjacent the lower portion thereof one or more tangential inlet conduits [6 through which the entering mixture of steam and water flows. The separating. members l5 are disposed with respect to the diaphragm 14 so that the tangential inlets are below the diaphragm and the upper open ends are above the diaphragm. The separating members extend preferably at spaced intervals throughout the length and Width of the horizontal portion of the diaphragm [4.
In operation, the steam and water mixture entering the drum through the tubes ll, moves upwardly in compartment B and enters the one or more tangential inlets l6 of the separating members l5. The steam and water mixture moves in a circular, upward path in each separating member, and centrifugal force causes the water to move along the inner wall of the separators, while the steam will take positions radially inwardly of the water. At the top of the separating members, the water will spill over the upper edge and will flow across the horizontal portion of the diaphragm to the bodyof steam Like characters of reference refer to the same I free water I! which supplies the downcomer tubes I2, while the separated steam leaves the central portions of the tubular members and enters the outlet 13 in the upper portion of the drum, from which it is conducted to a superheater, or to a point of use not shown. With this arrangement, the steam and water are substantially completely separated, so that dry steam is withdrawn from the drum and steam free water is delivered to the downcomers and to the boiler tubes.
As shown in Figs. 2 and 3, the separating mem: ber I5 is provided with a central core it; which aids in imparting to the steam and water mixture the desired whirling motion to efl'ect complete separation of the steam and water.
In the form of separating member shown in Figs. 4 and 5, a whirling motion is imparted to the steam and water mixture by means of vanes l9, instead of by one or more tangential inlets. The vanes l 9 extend from, or are connected to, a central member 2| which is arranged to prevent the passage of steam and water therethrough. In this arrangement, the tubular member is open at the bottom and the vanes are disposed in the lower portion of the member. The steam and water mixture enters the separating member through the series of spiral passages zfl formed by the vanes I9, with the result that a whirling action is imparted to the mixture. The water will be thrown toward the wall of the separating member and the steam will be separated from the water, with the operation being carried out substantially as described in connection with Figs. I to 3.
In accordance with the invention, it will. be perceived; that the" component parts of the vapor liquid mixture are completely separated readily and 'efiicientl'y, and without thenecessity of utilizingcumbersonrearrangements. The operation is such that dryvapor is obtained and vapor free liquid is delivered to the vaporizing tubes of 'the vapor generator.
It will be understoodthat changes may be made in the particular form and arrangement of the various parts .of the apparatus illustrated without departing from the principles of the invention, which. is not to be limited excepting by the scope of the appended claims.
