Definitions
- the present invention relates to a gas-liquid separator for separating at least one liquid constituent from a gaseous constituent, the gas-liquid separator being integrated in a housing of a recirculation pump and a separation of at least the liquid constituent of the medium takes place, in particular for use in a fuel cell system of vehicles with a fuel cell drive.
- gaseous fuels will also play an increasing role in the future.
- gas flows must be controlled.
- the gas flows are no longer controlled discontinuously as in the injection of liquid fuel, but the gas is taken from at least one high-pressure tank and passed to an ejector unit via an inflow line of a medium-pressure line system.
- This ejector unit leads the gas via a connecting line of a low-pressure line system to a fuel cell.
- an exhaust gas which consists in particular of unused hydrogen and a non-active portion, in particular water and nitrogen, recirculated via a recirculation path.
- the components H 2 O and N 2 are separated by means of the centrifugal principle from the medium by the gas-Flüsstechniksab separator. Furthermore, the medium is accelerated in the flow direction when flowing through the first and / or the second taper. In addition, as the medium flows through the bend in the direction of flow, the medium experiences such a deflection that the components H 2 O and N 2 experience a higher deflection and the light component H 2 a lower deflection due to their dimensions. In this way, the advantage can be achieved that the deposition process is improved by the gas-liquid separator in such a way that the components H 2 O and N 2 are almost completely separated from the medium, in particular from the H 2 .
- the collecting container 12 is at the outer radius 17 of the curvature 19 arranged net.
- the constituent H2 during the deposition process, advantageously flows out into the collecting container 12 with the H2O and N2. Since this H2 is not lost for the further energy generation process in the fuel cell system 1, a return of hh from the collecting container 12 via a suction connection 9 into the inflow channel 7 of the recirculation pump 9 is provided.
- the collecting container 12 has a discharge valve 46 in its lower region, the discharge valve 46 being connected to a sensor 22.
- the gas-liquid separator 2 As shown in FIG. 1, the gas-liquid separator 2 according to the first exemplary embodiment is located downstream of the compressor chamber 26 of the recirculation pump 9 in a flow direction II, the gas-liquid separator 2 being located in particular in the region of the outlet 18.
- the pump from the high-pressure tank 27 in the intake of the jet 10 flowing and serving as a driving medium H 2 has a Druckdiffe difference to the recirculation medium, which flows into the intake, the propellant in particular a higher pressure of at least 10 bar has.
- the jet pumping effect adjusts the recirculation medium with a low pressure and a small flow in the measure in the suction to the jet pump 10 promoted.
- the driving medium flows with the described pressure difference and a high speed, in particular special close to the speed of sound, in the intake.
- the driving medium hits the recirculation medium, which is already in the suction area. Due to the high velocity and / or pressure difference between the propellant and the recirculation medium, internal friction and turbulence between the media is created.
