- Connection may be provided, for example, the use of electric pumps with energy buffering in four-quadrant operation.
- an energy or power coupling of the pump for pumping seawater with the pump for re-discharging the seawater is realized in that the two pumps are designed as piston pumps whose pistons are coupled to each other via a common piston rod, wherein the pistons of the two pumps have the same size piston surface.
- the movement coupling of the two pumps is expediently such that the second pump for re-discharging the seawater, when the pump for feeding seawater sucks this from the outside environment of the submarine, discharges the seawater with the gas dissolved therein into the outside environment and the second pump for re-discharging the seawater, when the pump for discharging seawater discharges the seawater into the pipe joint, sucks seawater with the gas dissolved therein from the pipe joint.
- the pistons of the two pumps are connected to each other via the common piston rod and have the same size piston surfaces, the energy required during operation of the two pumps, which of a movement connected to the piston rod is limited
- Linear drive is provided, only to overcome the occurring during operation of the two pumps dynamic pressure losses and friction forces.
- the arrangement of a gas separator is provided according to a further advantageous embodiment of the invention on the output side of the means for introducing gas.
- the gas separator is used, possibly still in the form of bubbles in the
- the gas separator preferably has a gas outlet opening into the outside environment of the device, via which the insoluble gas can be discharged from the gas separator.
- This gas outlet is preferably closed by a controllable valve, which preferably by a
- Pressure sensor is controlled.
- Seawater into the outer environment of the submarine is preferably formed by a further pump whose outlet is connected to the line connection.
- This pump the inlet of which is expediently in fluid communication with a gas generator or a gas storage or a gas collection point, may expediently as a function of that in the line connection
- Seawater stream can be passed, which can go in this seawater stream maximum completely in solution.
- a controllable valve is arranged, via which the gas flow to the pump in a suitable manner can be throttled or adjusted.
- This valve can be both a shut-off valve which only permits discrete switching positions and also a proportional valve.
- Such a valve may also be provided on the input side of the pump if the gas to be conveyed into the line connection is already under pressure, for example in a compressed gas reservoir, and to a pump for introducing the gas into the line connection between the pump and the conveyor Seawater and the pump for recovering the seawater can be dispensed with.
- the valve alone forms the means for
- the pump for introducing gas into the line connection is basically arbitrary, as long as it is for conveying a gaseous fluid suitable is.
- the pump may advantageously be a water jet pump which is arranged directly in the line connection between the piston pump for conveying seawater and the piston pump for re-discharging the seawater.
- the use of a water jet pump proves to be particularly advantageous in terms of energy, since in a water jet pump, the seawater flowing through the pump acts as a propellant for the gas to be introduced into the line connection.
- a piston pump used for introducing gas into the line connection may be equipped with its own drive. But is preferred
- the piston pump for introducing gas and the piston pump for conveying seawater synchronously perform their respective intake stroke and their exhaust stroke.
- a second water supply opens on the gas separator.
- This water supply is preferably in communication with an internal water supply of the submarine.
- the gas separator expediently has a second water outlet. This second water outlet preferably opens in the interior of the
- the gas separator preferably has a fill level sensor.
- a pressure sensor can also be provided on the gas separator which detects the pressure in the gas separator and controls a valve arranged on the gas separator, via which excess gas can be discharged from the gas separator, if required.
- the apparatus for discharging gas described above is intended for use in a submarine.
- the invention also relates to a
- the device is expediently arranged in its pressure body.
- the submarine is preferably a military submarine, in which the use of the device according to the invention proves to be particularly advantageous because with the device so far in the
- the invention is based on a shown in the drawing
- the drawing shows in a schematic simplified schematic diagram a pressure hull 2 of a submarine with a device 4 arranged therein for discharging gas from the submarine.
- the device 4 has a
- the pump 6 can receive seawater from the outside environment of the submerged submarine.
- a pipe 12 forms a line connection to the inlet of the pump 8. From the outlet of the pump 8, a line 14 leads into the outside environment of the pump
- the pumps 6 and 8 have a common piston rod 16, that is, a piston 18 of the pump 6 is rigidly connected via the piston rod 16 with a piston 20 of the pump 8.
- a motor-driven linear drive 22 is used in this linear drive 22 may be a spindle drive, in which case the piston rod 16 forms an axially movable spindle of the spindle drive.
- a piston rod 24 of a further piston pump 26 is directly coupled for movement.
- gas present in the pressure body 2 of the submarine is introduced into the pipeline 12.
- an inlet line 28 is connected to the piston pump 26, which is connected at its end facing away from the piston pump 26 end with a gas source, not shown in the drawing for reasons of clarity.
- a line 30 leads to the pipe 12. Downstream of the mouth of the line 30, a gas separator 32 is integrated in the pipe 12.
- the operation of the device 4 for discharging gas is as follows:
- a controllable shut-off valve 34 arranged in the inlet line 10 is open and a controllable shut-off valve 36 arranged directly on the outside of the pump 6 is closed.
- the piston pump 26 performs an intake stroke simultaneously with the pump 6, so that gas is drawn in via the inlet line 28 from the piston pump 26.
- a controllable shut-off valve 38 arranged on the input side of the piston pump 26 in the inlet line 28 is open and a controllable shut-off valve 40 arranged on the output side in the line 30 is closed.
- Piston pump 26 sucked amount of gas adjustable.
- an exhaust stroke of the pump 6 is caused by appropriate control of the linear drive 22 so that the seawater stored in the pump 6 is discharged into the pipeline 12.
- Pipe 12 arranged shut-off valve 36 opening. Simultaneously with the exhaust stroke of the pump 6, the piston pump 26 executes an exhaust stroke, wherein the shut-off valve 38 arranged in the inlet line 28 is closed and the shut-off valve 40 arranged in the line 30 is opened. The gas in the piston pump 26 now passes via the line 30 into the pipe 12, where it mixes with the coming of the pump 6 seawater and goes into solution in the seawater.
- the seawater contained in the pipe 12 passes with the gas dissolved therein in the gas separator 32. If in the gas separator 32 supplied seawater gas bubbles should still be present, these gas bubbles are deposited in the gas separator 32 and the Gas given the opportunity to be located in the gas separator 32
- the level of the gas separator 32 is controlled.
- a fill level sensor 48 is arranged on the gas separator 32. Based on the signals provided by the level sensor 48, either additional water or water is supplied to the gas separator 32 discharged from the gas separator 32. Additional water is supplied via a second water feed 50 which opens out at the gas separator 32, wherein a controllable shut-off valve 52 arranged in the water feed 50 is opened. Via a second formed in the gas separator 32
- Water outlet 54 if necessary, water can be derived from the gas separator 32 into the interior of the pressure hull 2 of the submarine.
- a controllable shut-off valve 56 arranged at the water outlet 54 is to be opened.
- the pump 8 performs an intake stroke during the exhaust stroke of the pump 6 and receives the seawater from the scrubber 32 with the gas dissolved therein.
- a controllable shut-off valve 58 arranged in the pipeline 12 between the gas separator 32 and the pump 8 is to be opened in an opening manner.
