Definitions

  • the invention relates to a method for Druckgasver.sorgung, in which a liquefied gas is removed from a storage container, pumped to a higher pressure by means of a feed pump, at least partially evaporated and fed to a consumer under pressure, and a device for carrying out the method.
  • compressed gas e.g. Natural gas, oxygen, nitrogen, noble gases, etc.
  • these gases are generally liquefied and stored in a liquid state in pressure vessels. If necessary, liquefied gas is removed and pumped to a higher pressure.
  • the feed pump is driven by an electric motor or internal combustion engine. In the case of direct removal from a pressure vessel, its operating pressure must be at least equal to the consumer pressure and must be maintained by separate devices.
  • the liquefied gas is then evaporated or, if the consumer desires a partially liquefied gas, partially evaporated.
  • the invention is therefore based on the object of developing a method of the type mentioned at the outset, which has a lower energy consumption and / or reduces the investment costs for storage by lowering the pressure level, and reduces the safety risks.
  • This object is achieved in that a pressure above the required discharge pressure is generated during the evaporation and the resulting pressure difference between the evaporator and discharge pressure is used to drive the feed pump.
  • a pressure above the required delivery pressure is set in the evaporator at the start of the process. As soon as this pressure is reached, the evaporator is only supplied with the energy required to generate the desired amount of gas at the required pressure.
  • the existing pressure potential between evaporator and discharge pressure is used to drive the feed pump.
  • the pressure difference between the pressure actually generated and the pressure required by the consumer is, for example, 3 to 10 bar.
  • the method according to the invention is therefore not necessary to meet the need for electrical energy or fuel free of charge.
  • At least part of the vaporized gas is fed to the working space of a drive unit.
  • the gas from the drive unit is fed to the consumer after the work has been done.
  • a device for carrying out the method according to the invention comprises a storage tank and a feed pump, which is connected on the suction side to an extraction line leading from the storage tank and on the pressure side to an evaporator connected to a feed line leading to the consumer and is characterized in that the feed pump is coupled to a drive unit whose work space is connected to the delivery line.
  • a compressed air motor especially in the case of rotary pumps
  • a drive cylinder in particular in the case of piston pumps
  • the drive unit is designed as a drive cylinder and a control slide is provided between the delivery line and the drive cylinder.
  • the control slide valve which is actuated pneumatically, fulfills the purpose that the compressed gas is guided into its working space depending on the piston position of the drive cylinder.
  • a pressure reducing valve is arranged downstream of the Connection of the drive unit.
  • the pressure reduction valve which is designed, for example, as a spring-loaded check valve, builds up a pressure in the delivery line and in the evaporator which is above the pressure desired by the consumer.
  • the drive unit and / or the control slide are arranged in a pressure-resistant housing.
  • the gas after it has left the drive unit, first enters the housing and only then from there into the delivery line leading to the consumer.
  • FIG. 1 shows a flow chart of the method according to the invention.
  • a liquefied gas 1 is stored in a heat-insulated storage container 2 at a pressure of approximately 1 bar.
  • an extraction line 3 leads via a valve 4 to a feed pump 5, which e.g. is designed as a piston pump.
  • An exhaust pipe 6 leads back to the gas space of the storage container via a valve 7.
  • a safety valve is provided with reference number 8.
  • a connecting line 10 leads from the feed pump 5 to an evaporator 11, which is heated, for example, with ambient air.
  • the suction and pressure sides of the feed pump 5 are connected to one another via a bridging line 12, which contains a spring-loaded check valve 13.
  • a line 14 branches off from the connecting line 10 and carries a valve 15 at its end.
  • the feed pump 5 is coupled to a drive unit 18, which in the exemplary embodiment shown is designed as a drive cylinder.
  • a drive unit 18 which in the exemplary embodiment shown is designed as a drive cylinder.
  • a line 19 which is connected to a control slide 20, which has the function of a pneumatic switch and connects line 19 alternately via lines 21 and 22 to the current working space of the drive cylinder, as later will be described later.
  • Two roller lever valves 23 are connected to the control slide 20 and are actuated by a cam 24 on the cylinder rod of the drive cylinder.
  • the drive cylinder, the control slide 20 and roller lever valves 23 are accommodated in a pressure-resistant housing 25, the interior of which is connected via a line 26 to the delivery line 16 behind the check valve 17.
  • a pressure regulator 27 is located in line 26.
  • the system described works as follows:
  • the liquefied gas stored in the storage container 2 without pressure is to be supplied to a consumer in gaseous form via line 16 at a pressure of, for example, 15 bar.
  • the valves 4, 7 and - during the start-up - the valve 15 are open.
  • Liquefied gas enters the feed pump 5 via line 3 returned to storage tank 2.
  • the liquefied gas is pumped to the evaporator 11 via a connecting line 10.
  • valve 15 is closed.
  • a pressure builds up in the evaporator system, which is above the consumer pressure because of the spring-loaded check valve 17.
  • the pressure that arises in the evaporator 11 is 25 bar and is thus 10 bar above the consumer pressure.
  • a part of the gas from the evaporator gets into the control slide 20 and from there, depending on the position of the piston in the drive cylinder, into the left or right cylinder chamber.
  • the piston initially moves to the right from the position shown, then the left cylinder chamber is the working space and the gas reaches it via line 21 until the piston has reached its right reversal point.
  • the right roller lever valve 23 is actuated by the cam 24, whereby a pulse is transmitted to the control slide 20.
  • the control slide then switches its position and connects line 19 to line 22.
  • the gas from the evaporator now reaches the right cylinder chamber and moves the piston to the left.
  • the gas from the left cylinder chamber is ejected into the housing 25, from where it reaches the delivery line 16 and the consumer via line 26.
  • the cam 24 actuates the left roller lever valve 23, which transmits a pulse to the control slide 20, which then connects line 19 to line 21. In this way, a constant reciprocating movement of the piston is achieved, which drives the feed pump 5.
  • the consumer pressure of 15 bar is set on the pressure regulator 27. If the gas pressure falls below the target pressure at the consumer tapping point, the pressure regulator 27 opens and the gas volume flow required for the drive increases. This causes an increase in the number of strokes of the piston and thus in the delivery capacity of the delivery pump 5. This increases the pressure at the evaporator 11. However, since the pressure difference at the check valve 17 is set constant, the consumer pressure also increases. Conversely, when the setpoint is exceeded, the pressure regulator 27 closes, ie the number of strokes of the piston decreases and the pressures on both sides of the check valve 17 decrease.
  • the pressure vessel 25 is not absolutely necessary. However, if the drive cylinder 18, the control slide 20 and the roller lever valves 23 are omitted, they must be designed for the evaporator pressure, whereas if the container 25 is present, they only have to be designed for the differential pressure set on the check valve 17.
