Definitions
- the invention relates to a system for desalination of water by reverse osmosis, with pressurized chambers, with important characteristics of energy use, functionality and reduction of chamber size, since it is possible to increase the speed of water in filling and emptying of this.
- the Spanish patent application ES 9701877 of the same owner describes a water desalination plant by reverse osmosis in which the pressurized nurse chambers are cylinders in whose interior a piston circulates to separate the bodies of water of different salinity. Even when the operation is extremely satisfactory, it has been found that for large installations the inversion of the movement of the water bodies and the piston at the end of each of the pressurization cycles of the nurse chambers is not convenient, since the kinetic energy to dissipate can be considerable.
- the present invention is based on a radically different concept, such as that of a continuous kinetic cycle, consisting of the masses of water of different salinity circulating through the nurse chambers always do it in the same direction, and without stopping, it is not necessary to dissipate the kinetic energy of the mobile water body to accelerate it again in the opposite direction. This produces energy savings and decreases the size of the considerable cameras while improving the reliability and lifetime of the equipment.
- the first and main feature of the system is that the pressurizable nurse chambers that can be two or more where the water to be desalinated is stored have no rectilinear tube shape, and that can be with or without a water separating piston to be desalted and the brine.
- the chamber that we will describe has a ring shape in such a way that the beginning and end of the tube are joined, forming a closed circuit, which can be a toroid or a continuous zigzag tube, in a helical form, or in a whimsical way or functional that occurs to us, the only condition is that the beginning and the end are united in such a way that they form a closed loop or ring loop circuit.
- the second characteristic is that when the system has a piston, it has a spherical shape like a balloon, so that it can circulate in the curves of the continuous tube, and so that its weight approximates the density of the water, so that it is dragged by the current and also not be centrifuged in the curves due to excess density.
- the material can be any, metal or plastic, etc.
- the third feature is that there is a mechanism for collecting or parking the ball or piston, a kind of baseball basket or glove, ready to pick up the sphere and return it in the same direction and direction as it was, combined with a fork of the fluid to through a non-return valve of special design that opens with the inertia of the water, in such a way that when closing the entrance of the water to the chamber the mass that is rotating inside it is not slowed down but is free to circulate in the ring, at the expense of the kinetic energy that this moving mass possesses, without having to stop it and restart it as it would in an alternative piston movement, the only thing that has to be stopped is the small mass of the sphere-shaped piston in case you carry it
- the system also includes pump valves and systems for detecting the position or location of the piston, all of this operating in a programmed way to achieve the desired result.
- the main drawback that can be crossed out to this system is the excessive size that these chambers could have. nurse and the size of these depends almost exclusively on the speed of actuation of the valves, and the frequency of change of chambers If the valves act slowly one of the chambers has to have water reserve to cover the dead time in which the valves are changing state, for this reason if the operation of these valves were instantaneous and frequent if the stopping time between one camera ends and another starts tending to zero we could think that the volume of these nurse chambers can be reduced to a few meters more of the system conduit tube
- Another problem that appears due to downtime in which the change from one nurse chamber to another is made, is that the auxiliary pump that alternately feeds both chambers has to stop when it fills one and starts again when it has to fill the other or there is also the little technical solution of leaving that the pump works in a vacuum or with
- valves that operate at the pressures of reverse osmosis in the membranes currently present where for seawater with salinities of 35,000 ppm the pressures range around 650 m d c a are classified within those of high pressure
- valves of large diameters due to the tightness that they require are normally valves with a certain rigidity of maneuver, and their pneumatic or hydraulic actuation which is the most common, slows down, so that a good operating time of these valves can be around the second and very fast with short-stroke actuation such as diaphragm, do not fall below times less than 500 milliseconds and we are not mentioning valves of large diameters
- valve is not relevant, no matter how sliding, such as those used in pneumatics or hydraulics. It can be linear or rotary, such as concentric cylinders with ports that coincide with the intended sequence or also of perforated rotary discs that face a fixed disk let the fluid out through other holes that serve as a collector All these valves, as they work at high pressure, make the part of the body that acts as a cover, discharge an effort on the port or outlet hole that will be as much as the product of the surface of the agu j ero by the pressure of the fluid, this can also be removed, if we in the valve body not an outlet in the periphery, but also other to do the same function located diametrically opposite, so the effort is compensated and the wear would be much less
- the first improvement consists in the introduction of two three-way slide valves mechanically coupled together.
- the normal and simplest in a three-way valve of the sliding type and cylinder with radial ports, is that the slide has a single throat, and that the central outlet of the three port lines is the common inlet or outlet, of such so that when the slide is on one side, the ports on this side are connected to the center, and if it passes to the other end, the center will also be connected with those on the other side.
- the six-way and two-throated valve described above has the disadvantage that the filling or emptying time of the nurse chambers is not the same for both, which makes the volumes managed in one and another nurse chamber different.
- the closing and opening sequence does not give the same times for one camera as for the other, since the first camera that closes is the last one that opens, and within this time interval, the second camera It has to open and close, the operating time of this second camera being much shorter.
- the first solution is that one of these three-way valves has a double throat in order to reverse its operation, that is, the ports that in the first case are open, are closed here and vice versa
- the second solution is to divide the Six-way valve, in two of three, and reverse the direction of travel from one to the other. This second solution would force us to include a mechanism so that when one slide goes in one direction, the other moves in the opposite direction.
- valves that are recommended are of the sliding type, with ports in the form of circular holes arranged radially, so that the pressures are compensated.
- the valves also have a double jacket or external housing that delimits several collector chambers, for these ports, individualized by means of annular separators.
- the aforementioned cameras are going to play an important role here, which is not only the collector that communicates the external connections with their corresponding ports, but allows the passage of the water from the nurse chambers when the recirculation valves open, allowing the water of the nurse chambers to circulate in a continuous kinetic cycle, or what is the same, the moment when the trapped liquid is left, by the closing of all its valves to the outside, they are opened the recirculation valves due to the effect of kinetic energy, and the water circulates in a loop, on itself, avoiding water hammers and keeping the body of water moving until the next and immediate operation.
- the second improvement consists in a previous depressurization of the nurse chambers prior to the discharge of the brine to the outside, which is favorable for the duration of the recirculation valves that in this way have a smoother operation.
- This previous depressurization is done by including some very small section ports that open immediately before the main discharge ports.
- the operation of any type of slide valve can be very diverse, hydraulic or mechanical pneumatic type, and its positioning is no problem with the current computerized systems with numerical control and stepper motors or similar.
- the third improvement consists of a mechanism of mechanical drive, very simple, and that moved by an axis of constant angular movement such as that of an electric motor, with a gearbox, can make the slide of the Valve has some waiting stops at the ends, when the nurse chambers are filled and emptied, and that also has a small stop or decrease in its travel speed at a point in its path corresponding to the "previous pressurization" as it is described in the Spanish patent application ES 9800098, in order to allow time for the nurse chambers, take the high pressure of the membranes, and the rest of the route is done as quickly as possible.
- This is achieved with a mechanism of planetary gears, of appropriate diameters, describing any point of the planetariums an epicyclic path.
- valves 4 mechanically operated (which are simplified in two three-way), 4 one-way backflow, 2 recirculation for each chamber (these two valves constitute the system key for do not stop the fluid and enable the continuous kinetic cycle), 2 prior pressurization, and 2 prior depressurization. 3 or.
- the cost of raw material and manufacturing labor is significantly reduced, access to a change for repair or maintenance is improved and, above all, the set of all the valves required for the operation of the desalination plant, not being necessary to perform more than the assembly of the pipes and the connection of the different pumps at the installation site. 4 or. It also solves with a perfect solution the problem of asymmetry of operation caused by the six-way valve since this, as described, determines that both mothers have different operating times and, consequently, must be of different volume.
- Figure 1 schematically shows the operation of the system at any point in the cycle, where you can see a chamber that is finishing providing its desalinated water content to the membrane, while it is almost full of brine (scratched area) spherically divided by the piston. At the same time, the lower chamber has just emptied its brine content, and is completely filled with new water.
- the piston in the form of a sphere is picked up by the basket, in the form of a "U" that looks through its open part to the right, which is where the piston has just arrived. It can also be seen that the living force of the water has opened a valve by a bifurcated path, so that the water has not stopped.
- Figure 2 shows the same system as the previous figure in a state where the basket of the first chamber has been rotated 180 ° to allow the piston to run from right to left. This is an operating time where the two cameras work by simultaneously contributing their content to the membrane.
- Figure 3 we see that the first chamber has been completely filled with brine and that the basket has collected the piston, and the brine flow has also opened the fork valve, while the chamber below is supplying new water to the membrane, while it is beginning to collect the brine from the rejection.
- the upper chamber renews its contents while pulling the brine outside, and the lower chamber works in a state of water supply to the membrane, while picking up the brine on the right side of the piston
- Figures 5 to 10 show a temporal sequence of the operation of an alternative version of piston collection that we call concealment.
- Figures 11 to 14 show a temporal sequence of the operation of an alternative version of piston pick-up that we call double piston.
- FIGs 15 to 18, which correspond to the same cycle times shown in Figures 1 to 4, show a variant of the system in which there is no separator piston.
- Fig. 19 to 21 show the same circuit with the same principle and with the same operation, but that being drawn differently might seem different. The only difference is that there will be more or less loss of charge, in the water, depending on the diameters referred to the circuit. It is that the chamber that closes in a ring, does not have the same diameter in its entire length, so that it You can put a section of one diameter and then another section that closes the circuit and has the non-return valve with a different diameter, or even with several sections with several diameters, nothing influences the principle of system operation

- Blank arrows represent low pressure while black arrows represent high pressure.
- the recirculation and non-return valves are represented in black when they are closed and in white when they are open.
- the system of the invention comprises two ring-shaped nurse chambers (5 and 5 ') provided with two pistons (7 and 7') in the form of a sphere that serve as separation partition between the water to be desalted and the brine. This piston is detected by piston approach sensors (29 and 29 '), and piston housing (28 and 28').
- the grilles (10) and (10 ') are protections for the possible tendencies of the piston to be channeled through the bifurcations (8) and (8').
- the baskets (6 and 6 ') that have a "U" shape with their open part facing left or right, are responsible for picking up the pistons (7 and 7') that have a spherical shape.
- These baskets have at their bottom a small check valve (30 and 30 ') that opens with very little pressure.
- the aforementioned chambers (5 and 5 ') take the water to be desalted (19) supplied by the auxiliary pump (1) through the non-return valves (13 and 13') when the valves (12 and 12 ') are opened.
- the internal circulation pump (3) provides water from the chambers (5) and (5 ') to the membrane (4) through the non-return valves (14) and (14').
- the pump (2) is the main or high pressure pump and provides the membrane (4) with just the flow rate that will be permeated and that will leave the system as product water (20).
- the operation is as follows:
- This water does not cross the membrane because it is in a closed circuit and its mission is to drag the salts, which has left the water that has permeated the membrane, and this depends exclusively on the high pressure pump (2). As long as the pressure of the high pressure pump (2) does not exceed the permeate pressure there will be no salinity residues in the membrane and the function of the internal circulation pump (3) is to only circulate water in a closed circuit between membrane and chambers .
- the basket (6) that will pick up the piston (7) is not in a position to receive it but is facing the opposite side, that is to the left of the drawing and the piston is coming from the right side.
- the chamber (5 ') of the lower part of this figure 1. has just been filled with new water and the piston has just entered the basket on the right side (6')
- the piston housing sensor ( 28 ') has detected the piston (7') and closed the discharge valve (12 ') by cutting the water filling of the auxiliary pump (1) through the duct (22') of the non-return valve (13 ') and the inlet duct (16 ').
- a particularly interesting alternative is that in which the piston is dispensed with, being defined by the mere dividing plane between bodies of water, the physical elements being replaced by certain process conditions, such as the need for a laminar flow regime and the assumption of certain limitations. , as is a certain degree of mixing in the dividing plane. All this in exchange for less complexity and greater fluid velocity, which can be definitive in systems that require a high degree of reliability in places where specialized labor is not available for maintenance work and the size is further reduced. of the cameras.
- FIG. 15 to 18 Such a system is shown in Figures 15 to 18 in which it can be seen that the nurse chambers are toric (but in the same way that the system mentioned above can be with straight and curved sections) to facilitate non-turbulent flow, having disappeared the piston and its associated detection devices, which are replaced by two flowmeters (31, 31 'and 32) that control the cycle changes of the nurse chambers.
- a synchronization of the flow meters (31, 31 'and 32) is carried out, but it is possible to detect the position of this plane of separation, with the sensors of salinity, conductivity, etc. of the preferred embodiment, properly distributed in convenient places, or simply timed.
- valves can not only close with great speed, but the shorter the operating time of each of them, and the successive actuation sequences of all, will be so much better, since on the one hand We take full advantage of the speed of the fluid, its kinetic energy, and also that the downtime of the auxiliary pump No. 1 can become zero.
- This stop time or inactivity of the pump n ° 1 that fills the chambers is due to an intermediate state in the sequence of operation, explained in detail above, and refers to a time where the two chambers are at high pressure contributing its content to the membrane.
- FIG. 24 An especially interesting variant of a preferred embodiment of the six-way manifold valve is shown in figures 24 and 25
- an assembly consisting of a hollow cylinder with a sliding piston in its case has been chosen. inside this piston being provided with circular throats and sealing means and the cylinder presenting the mentioned outlets whose references (101), (102), (103), (104), (105) and (106) correspond to the references of Figure 23
- Its sequence of operation is identical to that of the embodiment described in detail for Figure 22, with Figure 24 corresponding to position A and Figure 25 with position B, with no intermediate positions being represented
- Figure 26 shows schematically the continuous kinetic cycle system performed in accordance with the latest improvements introduced, with the rest of the desalination plant elements.
- the low pressure auxiliary pump (201) that supplies raw water to the auxiliary conduit (201 '), and the internal circulation pump (203), that manages the same amount of water as the auxiliary pump (201) and that corresponds to the same amount of rejected brine
- This internal circulation pump (203) works in a closed circuit with a small differential pressure, which corresponds to the pressure drop of the brine in the membrane, but its housing is subjected to the pressure of the high pressure pump (202) which manages the flow of the product water at the high pressure of perm eado
- the internal circulation pump (203) draws water from the presumed duct (223) which is under high pressure, and after passing through the membrane it comes out in the form of brine that enters through the return duct (224) also at
- the inlet valve (61) is constituted by an inlet slider (51) of a single throat (82), which slides axially inside an inlet cylinder (52), which configures in joining an input housing (50) an annular space.
- This input space is divided into a first manifold (77), a central manifold (78) and a second manifold (79) by means of a first annular separator (53) and a second annular separator (54).

- the central inlet manifold (78) is also in communication with the inner cavity of the inlet cylinder (52) thanks to a plurality of central inlet manifold ports (81) located in its middle plane.
- the inlet valve (61) described is symmetrical with respect to this middle plane perpendicular to the axial axis thereof, whereby the second inlet manifold (79) is in communication with the inner cavity of the inlet cylinder (52) by means of equivalent second brine inlet ports (211 ') and prepressurization ports (74').
- the communication between the different collectors is possible or not depending on the position of the annular entry throat (82) that the inlet slide (51) has.
- the outlet valve (61 ') has a configuration similar to that of the inlet valve (61), except that the outlet slide (51') has two annular throats (86) (86 ') instead of just one, as was the case with the inlet slider (51.) Consequently, the possible communication between the inner cavity of the outlet cylinder (52') and the first outlet manifold (77 '), central outlet manifold (78 ') and second outlet manifold (79'), themselves configured as annular volumes comprised between the outlet cylinder (52 '), the outlet housing (50'), first annular outlet separator ( 53 ') and second annular outlet separator (54') is established by the following holes.

- Its configuration can be very variable depending on the size of the plant, speed chosen for the water ... etc. but overall respond to designs based on a lattice grid (95), concentric tubes (96), with radial sheets (97) or plurality of parallel tubes (98). See figures 45 to 47.
- the second nurse chamber (205 ') is in full activity, supplying its raw water content through the pressurized conduit (223) to the membrane (204) and receiving the brine through the return conduit (224).
- the situation of the slides (51) (51 ') allows a free path for the water that fills the second nurse chamber (205') and that, being at high pressure, keeps the backflow valve (213 ') closed.
- the non-return valve (214) remains closed, due to the lower pressure of the first nurse chamber (205) with respect to the pressurized duct (223)
- the water that circulates inside the first nurse chamber (205) has closed the outlet to the discharge duct (221) and the inertia that it carries in its movement, finding no outlet, opens the first recirculation valve ( 209) to allow the passage of water from the first outlet manifold (77 ') to the first inlet manifold (77) and enter the first nurse chamber (205) again through the flow mill (225) originating the first time in kinetic cycle. At this time all the brine that remained in the first nurse chamber (205) has been expelled.

- the time that elapses between the planetarium positions (93) represented in Figures 40 and 41 is a dead time in which there is no movement of the bridge (55), allowing the first mother nurse chamber (205) to be filled with raw water. the supply of all the raw water that occupies the second nurse chamber (205 ') through the pressurized conduit (223) towards the membrane (204).
- Figure 42 shows the moment at which the prepressurization ports (74) open and the positions of the different valves are those shown in Figure 31, the first nurse chamber (205) being in continuous kinetic cycle and the second nurse chamber (205 ') ending the supply of pressurized raw water.
- Figure 43 shows the moment of the previous depressurization of the second nurse chamber (205 ') with the valves being in the position corresponding to the figure
- figure 44 shows the end of the planetarium semi-cycle (93) starting a new dead period during which the supply of all the pressurized raw water that occupies the first nurse chamber (205) and the total filling with raw water of the second nurse chamber (205 ').
