Definitions
- the present invention relates to seawater desalination systems on board ships, in particular sailboats, and intended to provide drinking water to the occupants of ships when they are at sea, and relates in particular to a seawater desalination system operating with both alternating and direct current.
- Sailing yachts of a certain importance are more and more often equipped with a seawater desalination system making it possible to supply the drinking water necessary to the occupants of the boat when it is at sea for a certain time.
- a desalination system described in the article "Reverse-Osmosis desalination for shipboard potable water” by Adamson & Pizzino, published in the "Naval Engineers Journal, vol. 91, from April 1979, generally consists of a reverse osmosis membrane device through which seawater is forced under pressure so that only potable water crosses the membrane while most of the mineral salts is blocked by the membrane.
- a pump is required to force seawater under relatively high pressure of up to 65 bar, to pass through the membrane used to perform reverse osmosis.
- a pump drive mechanism is therefore necessary.
- This drive mechanism is generally a DC motor powered by the onboard battery which is recharged by a dynamo rotated by a wind turbine. It goes without saying that such a battery, sufficient to power the boat's lighting system, discharges quickly when it comes to powering an engine.
- sailboats have a generator supplying alternating current.
- the object of the invention is to provide a seawater desalination system, the pump drive mechanism of which is either a direct current motor or an alternating current motor. , the transition from one to the other takes place automatically without human intervention.
- a subject of the invention is therefore a seawater desalination system comprising a reverse osmosis cell (12) containing a semi-permeable membrane for carrying out the desalination of water by passing seawater under pressure. through the diaphragm, a pump for forcing seawater under pressure through the diaphragm and a pump axis drive mechanism comprising a direct current motor powered by a direct voltage and a AC motor powered by AC voltage.
- the motors are mounted in the pump axis drive position by a belt respectively driving a pulley at each end of the axis, each of the belts connecting the motor drive shaft corresponding to the axis of the pump so that each of the motors drives the rotation of the pump shaft when activated.
- the drive mechanism comprises declutching means resulting from the freewheeling assembly of each of the pulleys on the axis of the pump, so that the pulley corresponding to one of the motors is coasted when the other motor is activated to drive the pump axis.
- FIG. 1 shows schematically a boat in which a seawater desalination system has been installed according to the invention
- - Figure 2 shows schematically an embodiment of the seawater desalination system according to the invention showing the DC motor as well as the AC motor used to drive the pump.
- the desalination system according to the invention is shown diagrammatically inside a boat hull 10 in FIG. 1.
- the desalination is carried out using a reverse osmosis cell 12 containing a semi membrane -permeable.
- Seawater is sent under a pressure of at least 26 bars and up to 65 bars in cell 12.
- the water passes through the semi-permeable membrane but not the mineral salts. This makes it possible to obtain fresh water with a salinity rate below the legal threshold.
- the sea water to be desalinated is introduced by the action of the pump, through the inlet valve 14. This water first passes through a filter 16 which retains the particles having a size greater than a determined threshold. It should be noted that periodically the filter 16 must be cleaned and a rinsing of the sea water inlet pipe 15 is carried out.
- the filtered seawater is then sent via a pipe 17 to a pump unit 18 comprising a pump 20, a direct current motor (Ml) 22 and an alternating current motor (M2) 24, one of the two motors driving the axis of the pump 20 as explained below.
- a pump unit 18 comprising a pump 20, a direct current motor (Ml) 22 and an alternating current motor (M2) 24, one of the two motors driving the axis of the pump 20 as explained below.
- the pump 20 in operation forces seawater through the pipe 26 against the membrane located in the reverse osmosis cell 12.
- the fresh water collected at the outlet of the cell 12 by the pipe 28 is sent to a solenoid valve 30 which sends it through the pipe 32 to a fresh water tank 34 when its salinity level meets a certain quality of drinkability, or discharged it outside through the pipe 36 when the water collected does not have a quality of sufficient potability.
- the sending of water to one or other of the pipes 32 and 36 by the solenoid valve 30 is controlled by a control logic which can be a simple electronic card built in CMOS technology.
- the command transmitted by the control logic 38 takes account of the salinity of the sea water supplied by a salinity detector (not shown) comprising two electrodes measuring the salinity by resistivity. Two thresholds are measured, a potability threshold and a corresponding non-potability threshold in done at the legal threshold. When the salinity level is below the drinking water threshold, it means that the water is drinkable and it is therefore sent via the pipe 32 to the reservoir 34.
- the pump unit 18 according to the invention illustrated in FIG. 2 comprises a pump 20, the axis of which comprises a pulley mounted at each end of the axis.
- the pulley 40 is connected to the drive shaft of the DC motor 22 by a belt 42, and the pulley 44 is connected to the drive shaft of the AC motor 24 by the belt 46.
- Each of the pulleys 40 and 44 is mounted freewheeling on the axis of the pump.
- the direct current motor 22 drives the rotation of the pulley 40 via the belt 42 and therefore drives the rotation of the axis of the pump 20.
- the friction force exerted by the tree of the AC motor 24 being higher than the friction force exerted by the pulley, the pulley 44 is freewheeling, the belt 46 remains stationary and does not drive the motor 24.
- the pulley 40 remains stationary, the belt 42 remains stationary and does not drive the motor 22.
- An important characteristic of the invention is to supply only one of the motors in the case where the system has 12 or 24 volt power supply from a battery 48 and 220 volt power supply 50 supplied by a generator.
- the 220 volt alternative power supply has priority as illustrated in FIG. 2 which represents a first embodiment of the invention. Indeed, assuming that the DC motor 22 is powered by the single battery 48, the switch 52 is in the closed position. As soon as the generator set is started, the electromagnetic relay 54 is activated and the switch 52 opens, thereby cutting off the supply to the DC motor 22. Thus, only the AC motor 24 is supplied.
- the switching from the DC power supply to the AC power supply takes place automatically in the control logic.
- the control logic manages the various timers such as a 30 second timer implemented before being able to collect potable water in the tank after the system is started.
