Definitions

  • the present invention relates to a system for compressing gas, particularly combustible fuel gas.
  • Gas fuels of course, occupy a large volume unless they are stored at high pressure.
  • the vehicles even when large bulky fuel tanks are provided the vehicles usually have limited ranges. If gas fuels could be compressed economically and stored at higher pressures, the popularity of the modified vehicles almost certainly would increase because of the increased ranges of the vehicles.
  • the present invention provides a simple, inexpensive, safe system for compressing gas, particularly combustible fuel gas, to high pressure such as 1,034 107 N/m 2 (1500 psi) or higher.
  • DE-B-1 136 356 discloses a mechanism for charging a gas accumulator of a closed hydraulic system.
  • the accumulator must be disconnected form the remainder of the hydraulic system and part of the hydraulic system utilized in the procedure of recharging the accumulator.
  • the system requires constant monitoring and manual actuation of valves such as valve 9.
  • valves such as valve 9.
  • a mechanism for introducing gas forced from the working cylinders into storage cylinders without the use of manual actuation The system of DE-B-1 136 356 does not disclose a mechanism for draining liquid from a working cylinder without manual actuation.
  • gas is supplied at low or moderate pressure through an inlet in the top of a set of two working cylinders, such cylinders being alternately supplied with liquid through their bottom liquid inlets to alternatively force such gas from each cylinder into a storage tank or cylinder.
  • liquid is supplied to the other, as directed by an automatic control system including pressure switches, relays and variable position valves.
  • Check valves prevent backflow of gas from the storage cylinder to the working cylinders while the liquid is drained from the working cylinders.
  • the process is repeated until the pressure of gas in the storage cylinder is in the desired high pressure, such as 1,034 107 N/m 2 (1,500 psi) or higher.
  • the control system also senses the pressure of gas in the storage cylinder and automatically stops the gas-compressing process when the desired pressure has been reached.
  • the gas supplied to the working cylinder is low pressure gas which, prior to introduction into the working cylinder, is fed to an upright accumulator.
  • An outlet from the upper portion of the accumulator feeds the gas to a conventional, moderate pressure compressor driven by an internal combustion engine.
  • the engine is driven by gas supplied from the bottom portion of the accumulator.
  • the working cylinders and the storage tank include internal floats preventing any substantial mixing of gas in the upper portion of the cylinders with liquid in the lower portions of the cylinders.
  • Each float carries valve mechanism for seating in the upper gas inlet when the corresponding cylinder is filled with liquid and for seating in the bottom liquid inlet when such cylinder has the liquid drained from it.
  • a portable tank can be filled with gas from the storage cylinder by connecting the portable tank in parallel to the storage cylinder. Liquid can be pumped through a bottom liquid inlet of the storage tank for forcing gas from the storage tank into the portable tank.
  • a gas-compressing system in accordance with the present invention can be used to compress a combustible fuel gas to high pressure, to store the compressed fuel gas in a storage tank or cylinder, to allow quick transfer of the compressed fuel gas to a portable tank, such as a vehicle fuel tank, and to compress additional fuel gas automatically for storage in the storage cylinder or for direct transfer to the portable tank.
  • the main components of the system are: a moderate pressure gas-supplying component 1; upright working cylinders 2 and 3 receiving gas from the gas-supplying component; a conventional hydraulic pump 4 for supplying hydraulic liquid alternately to the working cylinders 2 and 3, respectively, so as to force the gas supplied to such cylinders out of them; and a larger, upright storage tank or cylinder 5 receiving the gas forced from the working cylinders.
  • Check valves 6, 7 and 8 control the direction of the flow of gas supplied by the gas-supplying component 1.
  • Variable position valves 10 and 11 control the flow of hydraulic liquid from a reservoir 12 to the working cylinders 2 and 3 and the storage cylinder 5, and from such cylinders back to the reservoir.
  • Such variable position valves are controlled by pressure-responsive switches 13 and 14 actuating relays 15 and 16.
  • a relief valve 17 drains hydraulic liquid pumped by the pump 4 back to the reservoir 12.
  • Another pressure-responsive switch 18 senses the pressure of the fuel gas in the system and automatically closes a valve 19 controlling supply of gas to the gas-supplying component when a desired pressure is reached.
  • An outlet connection 20 is provided for quick coupling to a mating connection 21 of a portable tank 22, such as a vehicle fuel tank, allowing transfer of gas from the storage cylinder 5 to the portable tank.
  • a pressure gauge 23 indicates the pressure of the gas in the portable tank when it is connected to the gas-compressing system.
  • the fuel gas is fed at low pressure to the gas-supplying component 1 through an inlet conduit 24 having the primary gas supply valve 19 to the inlet of an upright accumulator 25.
  • An outlet conduit 26 from the upper portion of such accumulator feeds the gas to a conventional, moderate pressure, mechanical compressor 27 driven by an internal combustion engine 28 modified to run on the fuel gas.
  • Another outlet conduit 29 from the bottom portion of the accumulator supplies the fuel gas for running the engine.
  • the fuel gas is natural gas supplied from a gas main at a pressure of about 2,758 103 N/m 2 (.4 psi) above atmospheric pressure; and the compressor 27 increases the pressure of the fuel gas to about 1,379 106 N/m2 (200 psi).
  • the compressor discharges the moderately compressed gas through an outlet conduit 30 and a tee 31 which branches to inlet conduits 32 and 33 which supply the gas to the upper portions of the working cylinders 2 and 3, respectively.
  • Check valves 6 in the inlet conduits 32 and 33 prevent backflow of gas from the working cylinders to the engine-driven compressor.
  • An inlet conduit 34 for supplying gas to the upper inlet of the upright storage cylinder 5 has branches 34' and 34" communicating with the working sylin- der inlet conduits 32 and 33.
  • Such branches 34' and 34" have check valves 7, each check valve being interposed between one of the working cylinder inlet conduits and the storage cylinder inlet to prevent backflow of gas from the storage cylinder to the working cylinders, or flow of gas between the working cylinders.
  • Conduit 34 also serves as the outlet conduit from the storage cylinder to the quick coupling connection 20, with check valve 8 preventing backflow of gas into the storage cylinder.
  • a pump inlet conduit 35 feeds hydraulic liquid from the reservoir 12 to the conventional hydraulic pump 4 which discharges the liquid through a pump outlet conduit 36 to the variable position solenoid valve 10.
  • a conduit 37 having the pressure-relief valve 17 branches from the pump outlet conduit 36 and discharges hydraulic liquid pumped by the pump 4 back to the reservoir 12 if a predetermined pressure is exceeded, such as 1,723 ' 107 N/m 2 (2500 psi) in a representative installation.
  • valve 10 is in the position shown in Figure 1 in which hydraulic liquid supplied through the outlet conduit 36 flows through such valve and a working cylinder supply conduit 38 to the other variable position solenoid valve 11.
  • valve 11 supplies the hydraulic liquid through the liquid conduit 39 for the working cylinder 2 to its bottom liquid inlet 40.
  • liquid from the pump supplied through conduit 38 is fed through a liquid conduit 41 to the bottom liquid inlet 42 for the other working cylinder 3.
  • valve 11 if valve 11 is in position to supply hydraulic liquid to the first working cylinder 2, any liquid in working cylinder 3 is drained through the valve to the reservoir 12 by another conduit 43.
  • valve 11 is in the position shown in Figure 3 for supplying hydraulic liquid to the second working cylinder 3
  • any liquid in the first cylinder 2 is drained to the reservoir through the conduit 43.
  • each float includes a buoyant body portion 50 loosely fitted in its cylinder but, nevertheless, of the same cross-sectional shape as its cylinder and substantially filling the space encircled by the upright wall of such cylinder.
  • Each float moves up and down with the level of hydraulic liquid in its cylinder and prevents any substantial mixing of gas above the float with hydraulic liquid below the float.
  • Each float also has a central valve mechanism 51, shown diagrammatically in Figure 2, including an upright axial shaft 52 biased to a vertically centered position by upper and lower helical compression springs 53.
  • a tapered upper resilient valve portion 54 carried at the top of the upright shaft 52 seats in the top gas inlet 55 when the level of liquid in the cylinder raises the float body to the top of the cylinder.
  • a tapered lower valve portion 56 seats in the bottom liquid inlet 40, 42 or 45 when the liquid in the cylinder is drained to the reservoir.
  • the floats prevent any flow of hydraulic liquid out the gas inlet of the cylinders and any flow of gas out the liquid inlets of the cylinders.
  • the "start-up" positions for the valves 10, 11 and 19 are shown in Figure 1.
  • the working cylinders 2 and 3 and the storage cylinder 5 are filled with gas at the moderate pressure determined by the gas-supplying component 1, such as about 1,379 ⁇ 106 N/m2 (200 psi).
  • Hydraulic liquid pumped through conduits 36 and 38 to the inlet conduit 39 for the working cylinder 2 raise the level of hydraulic liquid in that cylinder, moving the float 47 from the solid line position shown in Figure 1, through the broken line position to the top of the working cylinder. Consequently, the gas in the working cylinder is forced out of it and passes through the conduits 34' and 34 into the storage cylinder 5.
  • valve 11 alternating between the positions shown in Figures 1 and 3 until the volume of gas forced into the storage tank 5 is sufficient to increase the pressure in it above the predetermined pressure, such as about 1,655 107 N/m2 (2400 psi), which actuates pressure switch 18.
  • pressure switch 18 actuates closing of the primary supply valve 19, at which time the system is fully charged with gas at the desired high pressure.
  • the inlet connection 21 of the tank is quick-coupled to the outlet connection 20 of the gas-compressing system.
  • the gas-compressing system then can be switched to a "fast-fill” mode by changing the position of valve 10 from that shown in Figures 1 and 3 to the position shown in Figure 4. This is accomplished by means of a manual switch 57 for the relay 15 controlling the position of valve 10.
  • valve 10 With valve 10 in the position shown in Figure 4, hydraulic liquid from pump 4 flows through the valve and the storage cylinder liquid supply conduit 44 into the storage cylinder. The level of liquid in the storage cylinder increases, lifting the float 49 from the solid line position shown in Figure 4 and forcing gas from the storage cylinder into the portable tank 22. The pressure of gas in the portable tank is indicated by the pressure gauge 23.
  • the desired pressure of gas in the portable tank such as about 2400 psi, may be reached before the storage tank is filled with hydraulic liquid.
  • Pressure switch 13 is provided to sense the pressure of hydraulic liquid in the storage cylinder which is essentially the same as the pressure of the gas in the cylinder and the pressure of the gas in the portable tank. When the desired pressure is reached, pressure switch 13 actuates relay 15 to change the position of valve 10 back to the position shown in Figures 1 and 3.
  • an indicator light is provided to indicate when the gas-compressing system switches back from the "fast-fill" mode.
  • the portable tank can be disconnected or, if desired, it can remain connected to the gas-compressing system while the system alternates between the conditions shown in Figures 1 and 3 during which time both the storage tank and the portable tank will be charged to the predetermined pressure.
