No. 296,140 7 Claims. (Cl. 310-6) (Granted under Title 35, U.S. Code (1952), sec. 266) The invention described herein may be manufactured and used by or for the United States Government for governmental purposes without payment to us of any royalty thereon.
This invention relates to a device for directly converting thermodynamic energy into electrical energy.
One object of the invention is to provide an electrostatic generator wherein the mass to charge ratio of the working substance canbe varied over a wide range.
Another object of the invention is to provide an elettrostatic generator wherein the mass to charge ratio is substantially uniform.
These and other objects will be more fully understood from the following detailed description taken with the drawing wherein:
FIG. 1 is a sectional view of an electrostatic generator according to the invention;
FIG. 2 is a sectional view of a modification of the device of FIG. 1;
FIG. 3 is a partial sectional view of the device of FIG. 2 alongA the line 3 3; and
FIG. 4 is a sectional view of the device of FIG. 2 along the line 4-4.
Direct electrostatic-fluid dynamic energy conversion processes can be grouped into two large families, namely:
(a) Processes in which charged colloids or ions of one sign are transported against an electrostatic field by viscosity interactions with a gaseous or dielectric liquid working substance such Gourdines electric wind generator.
(b) Processes in which a major portion of the working substance is first transformed into kinetic energy of charged particles, which then transport the electric charges against an electrostatic field along a ballistic path. In this process the kinetic energy of the particles decreases as their electrical potential energy increases. The device of this invention relates to the use of the second process.
The major problems in the use of this second process lies in the production of high-speed charged particles having a suitable or uniform mass to charge ratio.
According to this invention energy for producing highspeed particles is taken from a pressurized gas employing an energy exchange process from the internal energy of the gas to kinetic energy of droplets, from the pressure head of gas from which the particles are produced. In prior art devices the chargeis added to the working substance after the expansion process. According to this invention the charge particles are seeded into the working medium prior to the expansion process so that the charge particles in the vapor flow serve as condensation nuclei around which the water vapor condenses during during the expansion process. This provides a substantially uniform mass to charge ratio. The mass to charge ratio can be varied over a wide range by controlling the rate of ion production for a given rate of condensation by varying the potential difference bewteen the needle electrodes and the grid electrode.
Referring now to FIG. l of the drawing, the drawing reference number refers to an electrostatic generator having a plurality of rows of needle electrodes l1 as shown in FIG. 3 adjacent a grid electrode 12. Expansion nozzles 13 of insulating material are formed adjacent the grid electrode l2 such as by molding around support members 14.
Spaced from the nozzles 13 are a plurality of receiving electrodes 15. The tip of the receiving electrodes adjacent nozzles 13 are coated with insulating material 16 arci-nd support members 17. Duets 18 are provided in the :eceiver electrdoes through which a cooling liquid such as water may run. A high pressure gas such as steam is supplied to the electrostatic generator through a ow duct 19 from a heat exchanger 20. The condensed gas is returned to the heat exchanger by means of a return pipe 21 and a pump 22.
In the operation of the device of the invention the high temperature gas from the heat exchanger 20 passes through flow duct 19. lons are seeded into the gas by the effect of the field between the grid 12 and needle electrodes 11. The gas is expanded in nozzles 13 so that a major portion of the gas is condensed to form small droplets of uniform size around the ions. At the exit of the nozzles 13 the major portion of the energy available in the working medium is transformed into kinetic energy of the charged droplets. As the particles pass betweenplanes 24 and 25 they are decelerated by the electric field effect between these planes. The charged droplets are further decelerated in the passages 26 be` tween the receiver electrodes 15. The cooling liquid from inlet tubes 28 in channels 18 cools any remaining gas, as shown in FIG. 4. The liquid passes out through tube 29 also shown in FIG. 4. The condensed liquid is returned to the heat exchanger 20 through return pipe 2l and pump 22 after it has given up its charge to the receiver electrodes 15. The sign of the potential applied to gn'd 12 and needle electrodes 11 is determined by whether negative or positive ions are to be seeded into the working medium. Also other working medium besides water can be used, for example, mercury or rubidium.
The gas which does not condense in the nozzle and which is condensed by the cooling liquid in channels 18 is lost energy. A greater portion of the working medium can be converted into useful working substance by modifying the device of FIG. 1 in the manner shown in FIG. 2 wherein a gas such as hydrogen, which does not condense in the expansion process, is added to the working substance through ducts 3l and channels 32 and inlet tube 34, shown in FIG. 3. The gas may be removed in a liquid gas separator 36 in any well known manner such as by gravity separation. The gas is then cooled in a standard type cooler 37 and supplied to tube 34' through a standard type gas compressor 38. Since hydrogen has a much higher heat capacity than the usual gases which are used as the working substance only a small amount of hydrogen is needed for cooling. The structure of FIG. 2 is otherwise the same as FIG. l.
While the ducts 3l and ehannels'32 are shown as being located within nozzle members 13, it is obvious that separate tubes and ducts could be provided either upstream or adjacent the nozzle members 13.
There is thus provided a device for direct conversion of thermodynamic energy into electric energy.
While certain specific embodiments have been described in detail it is obvious that numerous changes may be made without departing from the general principles and scope of the invention.
