Definitions
- the invention relates to a device for generating, storing and dispensing compressed air with a motor driving a compressor and a downstream wind boiler.
- the invention is based on the object of demonstrating possibilities for generating and storing compressed air in large quantities at high pressures, in order to deliver this to a consumer, for example a vehicle, as loss-free as possible.
- the wind boiler is connected via an air line to a high-pressure, stationary intermediate store to which a delivery station is connected.
- the buffer can be connected to an additional compressor via a changeover valve, which draws in air from the outside.
- the intermediate storage consists of a compressed air battery with several pressure containers that can be filled at the same time.
- the delivery station has a high-pressure-resistant line made of steel-rubber fabric with a connection piece for the pressure tank of a consumer, in particular a vehicle.
- the connecting piece has a closure electronically monitored by a pressure sensor.
- the air duct of the wind boiler is connected to a generator that generates electricity.
- the motor for supplying the wind boiler can have a wind power drive, consist of a water turbine or can be a direct current motor. In the latter case, this can be connected to solar cells that supply the electrical energy.
- Another problem is the different energy requirements during a day. In the morning, at noon and in the evening, the high energy requirement can only be partially covered, while almost no energy is required at night, so that the energy generated is lost.
- the engine consists of a water turbine
- the kinetic energy generated is usably stored in one or more wind boilers. Similar to the first embodiment with wind power drive, it can be used over longer periods of time by converting it into electrical energy in a downstream generator.
- the motor is a direct current motor which can be connected to solar cells.
- the currently known types of photovoltaic systems generate electrical energy using solar radiation. However, this energy has so far only been able to be converted into mechanical energy with very great technical effort. In addition, it was not possible to adequately store this energy and make it available at all times at a reasonable cost.
- Previously known delivery stations for compressed air are used, for example, to fill tires with a maximum pressure of 8 to 10 bar, the amount of air delivered being extremely small.
- the problem can be solved of quickly charging a vehicle with a tank volume of several tens of thousands of liters of compressed air to a pressure of 40 to 300 bar.
- Very high security requirements are to be satisfied here;
- high performance is required, for which there is as yet no solution suitable for everyday use.
- the dispensing station can be integrated and used at conventional petrol stations, with a corresponding monitoring unit electrically controlling and securing the refueling process.
- the driver or gas station attendant only has to connect and lock the connecting piece of the station to the filler neck of the vehicle.
- the locking can also be monitored via an electrical sensor, since the pressures that occur are very high.
- FIG. 1 shows a schematic overview of the possibilities according to the invention
- FIG. 2 shows an exemplary embodiment with a wind power drive
- Figure 3 shows a variant of Figure 2 with hydropower
- Figure 4 shows another variant with solar cells.
- Figure 1 shows schematically three ways to supply a wind boiler 10 with compressed air.
- the wind boiler 10 is connected to a compressor 12 which is driven by a motor 14.
- the motor 14 consists of a Pinwheel 14 '.
- the motor 14 consists of a water turbine 14 ′′, for example a Pelton turbine, which is supplied by a water reservoir 16.
- the motor 14 receives its electrical energy from solar cells 18.
- FIG. 2 shows the variant in which the motor 14 consists of a wind wheel 14 '. Its shaft 26 drives the shaft 30 of the compressor 12 via an angular gear 28, which directs the sucked-in and compressed air into the wind chamber 10. If necessary, the air of high pressure can be delivered via a connecting line 22 with a schematically drawn valve 20 to a generator 24 which generates electricity.
- the wind boiler 10 is connected via the line 22 to a delivery station 32, which will be discussed in more detail below.
- the water reservoir 16 can be seen which drives the water turbine 14 ′′.
- the rotational energy generated by the motor 14 drives the compressor 12 via a belt drive 34, which here supplies three wind boilers 10 connected in series. From these, the compressed air can be fed individually or as a whole either to a downstream generator 24, which can drive an air compressor 26, or to the delivery station 32 (FIG. 1).
- FIG. 4 shows the photovoltaic system in which the motor 14 designed as a direct current motor is supplied with electrical energy by solar cells 18.
- the motor 14 also serves to drive a compressor 12, which is connected to one or more wind boilers 10.
- the wind boiler 10 can be connected to a generator or the delivery station 32 via the air line 22.
- the possible application of FIG. 1 shows that the wind boiler 10, which can absorb pressures of approximately 100 bar, can be connected via the air line 22 to a stationary intermediate store 36, which absorbs very high pressures.
- this intermediate store consists of a compressed-air battery with a plurality of pressure containers 38 that can be filled at the same time.
- a line 40 leads from this intermediate store 36 to the delivery station 32, which can be monitored by a monitor 42.
- the delivery station 32 has a high-pressure-resistant line 44 made of steel-rubber fabric with a connecting piece 46 for the pressure tank of a consumer, in particular vehicle 48, not shown.
- the connecting piece 46 has a closure electronically monitored by a pressure sensor, not shown.
- FIG. 1 also shows that the intermediate store 36 can be connected via a changeover valve 50 to an additional compressor 52 which is driven by a motor 54 and draws in air from the outside.
- the suction line 56 provided for this is indicated.
