STEAM-REGENERATIVE ACCUMULATOR.

Specification of Letterslatent.

Patented Aug. 23, 1910.

Application filed October 1, 1906. Serial No. 337,004.

steam and liquid is effected within the vessel of the accumulator, which feature of my invention will be fully pointed out in connection with the preferred embodiment thereof shown in the drawing and which feature will be set forth in the claims.

My invention will appear by reference to the accompanying drawing. in which Figures 1 and 2 show the preferred embodiment of one. type of steam regcnerator. Fig. 1 is in sectional elevation and Fig. 2 is in sectional plan on line 9 9 of Fig. 1. Fig.

3 is a view illustrating another type of steam regenerator.

Like parts are indicated by similar characters of reference throughout the different figures.

Steam is admitted from any suitable source, such as the exhaust of a reciprocating engine, which steam finds its passage from the engine through the pipe a, which preferably communicates with a header so that the steam is admitted to this header before it is received into the chamber 0 of the accumulator. In the form shown in Fig. l, the chamber 0 is provided with a plurality of diaphragms d and 6 extending across the same, 'these diaphragms being centrally apertured, diaphragm d having a pipe f projecting upwardly therefrom and diaphragm e having a pipe 9 projecting upwardl therefrom. -Another diaphragm I1. is inc uded at the top of the vessel 0 so as properly to define the water and prevent its discharge through the outlet i for regenerated steam. The diaphragms (Z and c with their pipes .f and g and the wall of the chamber 0 constitute vessels, one superposed on the other. A third vessel is located below the two vessels just described, and is also contained within the chamber 0, the pi e g afiording a passage for steam escaping rom the tird or bottom vessel while the pipe f affords passage for the steam escaping from the intermediate vessel, while a central openmg 111 the diaphragm it through which the pipe f passes, permits the passage of the .steam from the top vessel, all of the steam from these three vessels passing into the escape pipe 2' to perform the duty for which it is adapted.

In order that the levels in the different vessels may be maintained uniform, openings f may be provided in the pipe f and openings in the pipe 9, located at the level to be maintained, the water flowing through these openings when it is about to exceed this level. By reason of this construction there is a constant to and fro movement of the water from chamber to: chamber, the water being finely divided as it falls from one chamber to a lower one by gravity through the steam in the main steam passage and being carried upward by the steam fronrsalosver to a higher chamber. Moreover, the greater the'amount of steam the greater will be the mean levels of the water in the various chambers so that an amount of water proportional substantially to the amount of steanrwill flow from an upper to a lower chamber through the up lowing steam. Under these conditions there a most intimate intermingling of steam and water the most important feature in a steam 'regenerator. The spraying of the water by means of perforations also has the advantage of preventing any pockets of water temporarily closing the steam passage and causing back pressure upon the flowing steam, which would be liable to occur if water from one chamber was allowed to pass through the steam passageto another chamber without being sprayed. \Vhere, as in Fig. 1, there are more than two chambers, the telescopic arrangement of pipes f and g still further assists the thorough intermingling of the steam and water in the to and fro movement of the latter, because it compels the Water falling from the upper chamber to pass tothe next chamber along the inside of one pipe and the outsideof the other, and

in like manner to pass from each vchamber to the next in thewholeseries. As a supplemental means'for maintaining the level in the two upper vessels, piping is maybe emvalve structure Z or any suitable means for permitting the overflow of the water when it .has accumulated in suliicient quantity from the lowermost vessel.

\Vhen there is a plurality of vessels employed in a regenerating chamber 0, as indicated in 1, several pipes or ducts m, a, 0 are employed, which convey the steam from the header Z) or any other suitable source into the vessels, to effect agitation of the liquid contained in said vessels and to occasion the intermingling of the steam conveyed through the pipes or ducts m, n, 0 with the liquid contained in the vessels. Ballieplates *1 p, p are providedone for each vessel-below which the pipes m, a, 0 have communication with the corresponding vessels, the liquid lying above the diaphragms p. In order that the liquid above the dia phragms 39 may also be brought effectively into agitation, I provide deflecting plates 9 in the diflerent vessels, that cause the liquid to be displaced obliquely. It will be seen that the discharge openings of the pipes m,

Y n, 0 are so far below the other ends of these pipes that. the liquid in the vessels cannot find back passage into the header 1). The pipes m, n, 0 are desirably led into the vessel 0 in a tangential direction, so that the fluid is caused to circulate tangentially, whereby the liquid in the different vessels is gyrated, and by reason of the gyrating motion or circulation thereof, most thorough intermixture of the steam and the liquid, which is preferably water, is permitted.

While I prefer to direct the pipe 0 into the vessel 0 as indicated in Fig. 2, I do not wish to be limited to this arrangement, for the construction shown in Fig. 3 may be employed particularly where the chamber a is horizontally disposed instead of being vertically disposed, as it is in the construction shown in Figs. 1 and 2. In the construction shown in Fig. 3, the horizontally disposed chamber 0 has a diaphragm 7 extending preferably throughout the lengtli of the vessel c and being desirably diametrically placed with reference to the vessel 0. The diaphragm, however, is disconnected from the longitudinal sides of the vessel 0 so that the liquid in the vessel may circulate.

The inlet pipe, lettered 0 in Fig. 3, may be projected into the liquid as there shown and may cause" a circulation of the liquid with the aid of the battle-plates r to cause the same gyrating action of the fluid in the vessel for the same purpose. While I have shown but one pipe 0 in Fig. 3 projected into a vessel c, I do not 'wishto be limited to the number of pipes.

In order that there may be a definite ratio of pressures in the chamber 0 and the header b, a branch pipe 8 is connected between these two elements, as indicated in Figs. 1 and 3,

a relief valve t opening whenever the pressure in the element 0 has exceeded a predetermined value.

By the apparatus illustrated an extremely high velocity within the generator is secured, so'that a most thorough interaction of the steam and liquid is secured for regenerating purposes.

The header 7) may possess as an additional function the capacity to spread oil and water, to which end the said header will be constructed in a manner well known to those skilled in the art.

It is obvious that changes may readily be made in the embodiments of the invention herein shown, withoutdeparting from the spirit of my invention, and I do not, there fore, wish to be limited to the precise constructions shown, but,

Having thus described my invention, I claim as new and desire to secure by Letters-Patent .1.
