Definitions

  • the present invention describes a system of static pressurized chambers with virtual rotation for energy saving in desalination of seawater by reverse osmosis.
  • the most efficient technology currently used for energy saving in reverse osmosis desalination comprises the use of chambers that are pressurized alternately, as explained below.
  • the procedure for desalination of seawater consists of circulating, driven by a high pressure pump, a stream of seawater pretreated by a membrane osmosis installation, where it is separated in water pure without pressure and a solution with high brine content still at high pressure.
  • the energy of that concentrate that exits at high pressure will be the one that is used to save energy.
  • a cylinder or tubular chamber provided inside a piston whose friction is minimal.
  • One side of said cylinder (for example, left side) has two valves, the seawater outlet V2 to the membranes and the seawater inlet V3 to the chamber.
  • the other end of the cylinder (for example, right end) connects a rejection inlet valve V1 from the membrane and a brine outlet valve V4 to the sea.
  • the chamber is filled with seawater with the valve V3 open and moving the piston to the right side.
  • the valve V1 opens and rejection brine begins to enter at high pressure, pushing the feedwater that leaves the valve V2 open towards the membranes producing the product water desalinated by the phenomenon of osmosis inversion.
  • valve V1 closes by opening V4.
  • low pressure seawater enters the open valve V3, which expels the brine by V4 filling the seawater chamber. From this moment a new cycle would begin.
  • the described device needs to solve a problem to function properly. This problem occurs because the transfer of pressure to seawater by the brine must be continuous. In the case described, while the plunger moves to the right, it does not propel seawater, which is not acceptable for the membranes since they would run out of water.
  • This problem is solved by installing in parallel at least a second chamber (second cylinder) whose operation must be out of phase with respect to the first one so that the membranes are permanently receiving high-pressure seawater from the chambers.
  • This set of cameras that form the system can be of two types: static or rotary.
  • Static systems handle large volumes of water, usually two chambers which, by means of a common mechanism that relates them at all times, mean that while one works by providing water to the membranes, the other chamber is replenished with seawater while throw away the brine that has been left as rejection or residue.
  • the larger the system is to be made the larger the cameras are and never divided into smaller cameras connected in parallel.
  • These static systems have large valves and large drive mechanisms.
  • a pair of tubes has at one end four 2-way non-return valves (eight ways in total) and at the other end four piloted two-way valves, (another eight ways) which, in some cases, to simplify, use only one Five-way valve operated by pneumatic or hydraulic or electrical systems.
  • Rotary systems (whose precursor was Klaus Eimer, 1979) are very simple because they have no valves, because the effect of these is achieved with the use of a perforated drum with longitudinal holes (of the order of 10 to 12) that make small chambers , with two covers at their bases as a port, where the water enters and leaves, which are connected and disconnected sequentially when the drum is rotated.
  • the main drawback of this system is that the cylinder base caps have to be tight to get a good seal, so that the water that is at high pressure does not leak, but that if it exceeds the adjustment, you can get to stop the rotation of the rotating drum. Therefore, this system requires great precision in its manufacture being the material used par excellence, since a high hardness is required to withstand friction at more than 1200 rpm having water as a lubricant.
  • the static cameras are for higher production volumes and the rotary ones, for the simplicity of the system, are built for small flows, since if they are used for large plants, many of these small devices must be connected in parallel.
  • the company Calder sells a system of static cameras called Dweer (Dual Work Exchanger Energy Recovery) consisting of two cameras of conventional type and with the five-way valve operated by an oil-hydraulic control unit.
  • Dweer Dual Work Exchanger Energy Recovery
  • the energy saving system marketed by Siemag is similar to the previous one, except that it basically consists of three static cylindrical chambers with valves, connected in parallel.
  • valves and the connecting elements between the valves and the chambers have a large weight and large dimensions, which implies a high cost of both manufacturing and maintenance.
  • Rotary camera systems also have a number of problems, such as:
  • the present invention aims to provide a hybrid system of static cameras that are provided with a virtual rotation, which solves all the technical problems listed above. It also combines sales- jas of both the large static cameras and the smaller dynamic, being able to manufacture for the entire range of volumes desired.
  • the invention comprises a set of unit elements consisting of pressurized static chambers connected in parallel.
  • Each of the unit elements has two non-return valves at one end.
  • On the other end a three-way valve is used, servo-driven piston or membrane, which is actuated by high-pressure water, preferably by the rejection brine of the membrane.
  • This drive system is not used in the state of the art due to the high corrosivity of the brine, however today the valves can be manufactured with materials, whether metals or polymers, which resist this high aggressiveness.
  • the set of valves of all the unitary elements is supervised and controlled by an electronic equipment that achieves, without the need to physically rotate the chambers, that the water flows behave exactly the same as they would in a rotary drum.
  • the rotating drums sequentially fill and empty the chambers due to the effect of drum rotation.
  • this sequential filling and emptying is not generated by the rotation of any mechanical element, but the sequence of orders programmed in the electronic equipment and sent to the piloted valves.
  • An improvement of the modular hybrid system, object of the present invention also refers to the design of the pressurized static chambers, also called isobaric or pressure chambers, which are tubular chambers formed by an internally plastic coated steel tube.
  • a loose or floating piston is housed, with a very special design without friction, which acts as a partition between the brine and the water to be desalted, as described in the P9701877 patent of the same applicant, where it is also describes a positioning system of said piston with magnets that are detected from outside the tube by sensors of the network type or Hall effect.
  • austenitic steels used in desalination and also those of ferro-austenitic and super-duplex duplex structures are permeable to magnetic fields and can pick up the signal.
  • This piston works perfectly stabilized with the density of water that is balanced without weight within the fluid.
  • soft rings are placed on that piston so that they rub only them, with hardly any pressure, since the differential pressure will be created by this segment, depending on how tight it is. In this way the piston will move with absolute precision and smoothness, without any effort, without loss of energy and without mixing the brine with the seawater.
  • this piston as it moves without pressure differential but because it is carried by the water flow, has a valve of special design, in the center, which operates in a bidirectional way, so that if it reaches the end of its path either one way or the other and the pressure acts above a preset value, the valve opens, as a safety measure, by allowing water to pass through.
  • valves in the isobaric chambers the water circulates in both directions with the intermediate piston described above.
  • the passive non-return valves that open and close with the flow of water that defeats a spring correspond to those of water that comes from the sea and are two, one for low pressure and one for high pressure, both being in the same side of the tube or isobaric chamber.
  • the other two valves, which correspond to the brine passage, are commanded and automatic and are on the same side of the chamber.
  • One of the two valves the one on the low pressure side, opens to expel the brine out of the chambers; the other valve, the one on the high pressure side, gives way to the high pressure brine that comes from the membranes to the chambers and that is responsible for pushing the seawater through the separator piston, which opens the high valve on the opposite side that goes to the membranes.
  • valves that open and close the passage of fluid to the chambers another of the advances that this invention entails is that they will be placed directly on the lid of the chambers that are pressurized, arranged in the same way and manner that they are in internal combustion engines, such as cars.
  • they can be two or four valves in the head.
  • valve seats are machined in the chamber lid or added to this cylinder head.
  • valves to be used are conical or flat seat plate and with a guide rod.
  • all isobaric chambers have the valves installed outside the chambers and connected to them by means of tubes left outside the chambers. This refers to the non-return valves, because those that are commanded, are always of the type of slides with louvres, rotary or ball, but never of the type all or nothing like those used in internal combustion engines, as is the case of The claimed invention.
  • valves in the caps of the chambers or cylinder head only the tubes remain outside achieving two essential objectives: the first is the saving in materials and workmanship of pipes and connection flange systems, which it translates into a significant decrease in costs and the second, much more important, is that as the chambers change pressure as they are filled with seawater at atmospheric pressure or they are displacing the membranes pushed by the high pressure of the rejection brine, the pipes that come out are also subject to these fluctuations together with their valves, connection flanges, gaskets and the corresponding hardware, which considerably increases the risk of breakdowns. In the case of the presented invention, none of this exists, which considerably increases the useful life and without breakdowns or leaks of the equipment.
  • This constant pressure in the four tubes connecting the chambers makes it possible to use the commercial joints (vitaulic joint type) consisting of a clamp made of two pieces that are joined with two thymes that compresses the two halves against a ring of an elastomer and that they have the advantages of the rapidity of the installation, integrity of the design, reliability of the operation but that cannot work with abrupt variations of pressure.
  • the constant pressure in the four connecting tubes has been exclusive to the rotary chambers, but not thought of in the static ones.
  • valves being of the type plate with stem, have a particularity in their design that consists in that, apart from the proper function of closing tightly by pressure seat which prevents dripping, it also leaves a small chamber of trapped water Between the lid and the body used to stop the impact of the closure, avoiding noise and extending life as tensions are avoided to the materials that are hit.
  • the lid has a series of small holes where the trapped water will escape with some slowness so that the contact is slower and consequently less abrupt.
  • This same series of holes has a second mission which consists in the fact that, when the chamber is with high pressure or, on the contrary, low, the valve that corresponds to it will open, will do so first with the holes that will act as pressure diffusers, so that the pressures are balanced gradually and not at once, thus avoiding the great noise that originates in the pressurized chambers caused by this static pressure stroke.
  • a great advantage offered by the system of the invention is that the valves are commanded by an electronic system with great speed and accuracy of response, so that a chamber that is empty can be opened and made to coincide with the closure of one that is has filled, without having to stop the feed water.
  • the electronic equipment When the system detects breakdown or breakage in any of the chambers, the electronic equipment immediately applies a lag so that the number of chambers that are supplying the water to the membranes remains constant and the missing chamber is passed to the low zone. pressure, filling that fault with a slight increase in feedwater pressure.

Abstract

L'invention porte sur un système hybride modulaire de chambres statiques à rotation virtuelle pour une économie d'énergie lors du dessalement par osmose inverse. Ce système comprend une installation d'osmose avec une membrane où l'eau de mer est séparée en eau dessalée et en saumure de rejet à pression élevée, laquelle est amenée à passer par une ou plusieurs chambres tubulaires pressurisables. Le système comprend une série d'éléments unitaires, chacun d'entre eux comprenant une chambre tubulaire classique avec deux clapets antiretour à l'une des extrémités et, à l'autre extrémité, un robinet à trois voies servopiloté à piston ou membrane, qui est actionné par la pression de la saumure de rejet en provenance directe de la membrane. Les éléments unitaires sont surveillés et commandés par un équipement électronique permettant d'obtenir, par maniement des soupapes, une séquence qui, sans nécessité de faire tourner physiquement les chambres, amène les flux d'eau à se comporter exactement de la même manière que dans un système classique à chambres rotatives.
