Abstract

There is disclosed a device (2) for treatment of water/liquids which comprises a tubular element (3, 4, 6) comprising two passages (11, 13) in which there are housed a first guide plate (10) and a second guide plate (14) which are spiralled in opposite directions around their centre axes (18), and where inside the straight, tubular element (3, 4, 6) there is provided a shorter, straight, plane plate-shaped piece (60, 62) which is disposed between the first spiralled guide plate (10) and the second spiralled guide plate (14), so that the ends of the shorter plate piece (60, 62) facing the spiralled guide plates stand in extension of and are level with the corresponding ends of the spiralled guide plates (10, 14). The guide plates (10, 14) divide the passages in the tubular element into two or more parts in which water/liquid can flow, whereby this is influenced to assume a preferred direction of flow, depending on the hemisphere in which the device is installed, by which influence particles contained in the water, e.g. lime, do not form deposits in a subsequent water station, neither in pipes nor at tapping places. The device (2) also has an advantageous effect on the quality of many other aspects of liquids which are treated by flowing through the device.

Description

Device and method for treatment of water and other liquid materials.

The present invention relates to a device for treatment of water or other fluid material, and comprising a straight, tubular element with an outer wall which de- fines a through-going passage with an inlet end and an outlet end with a longitudinal axis, and a first elongated guide plate and a second elongated guide plate placed in the through-going passage, said guide plates being spiralled with mutually opposite convolutions in relation to/around said longitudinal axis, and where said guide plates are accommodated in said through-going passage for dividing this in two parts for guiding water or other fluid material a\ong said divisions of said passage from the inlet end to the outlet end, where the straight, tubular element comprises at least two passages with spiralled guide plates.

Such a device is known from EP 1 428 797 A1 , which discloses a "Water re- vitalizer" for connection to a water installation, comprising two spaced, spiralled guide plates placed in an enclosed pipe in a cabinet, where around the enclosure, in the space between the spiralled guide plates, there is provided a generator which provides a characterisation of the water, which is hereafter fed back to the water installation via a perforated, bent plate in the outlet end of the enclosure, and a further spiralled guide plate housed in an outlet stub on the cabinet. The effect of the device should be that the macro-molecular characteristics in the water which is led through the device shall be broken down into smaller macro- molecules, which should reduce the surface tension of the water. The device appears to be quite complicated, and alone the establishing of pressure-tight pas- sages for inlet and outlet pipes through the cabinet will give rise to relatively great production costs.

From PCT/DK2002/00263 there is known a more simple device in which there is disclosed a pipe piece intended for mounting on a water installation or an installation for other fluid material for treatment of water or other fluid material, said pipe piece comprising a guide plate which is spiralled 360.000° which divides the clearance in the pipe into two half parts, and where under passage of the pipe the water/fluid is given a through-flow to the right or to the left , all depending on how the pipe piece is mounted, which depends on whether the device is mounted on one of said installations in the northern hemisphere (turning to the right) or the southern hemisphere (turning to the left). The effect of the device is, for example, that the water's content of lime, which will normally be precipitated and adhere to the inside of the pipe installation, e.g. in a home, seldom adheres in neither the pipe nor on flat surfaces in connection with tapping places e.g. sinks, washbasins, washing machines, dishwashing machines etc. The device has also proved to be usable in the removal of odour in clean water supplies, and use of the device for treatment of drinking water for domestic animals has been able to relieve salmo- nella problems among livestock.

It is recognised that the new technique according to the invention in general offers an improvement of the quality namely of fresh water, but also the quality of other liquids such as, for example, soft drinks and beer, wine products, juice and other similar beverages. Notwithstanding that the physical and technical background for the surprising results which are achieved with the use of the above- mentioned device is not clear, and despite the fact that a precise description and explanation of the technical effect of the device it not at present accessible, practical utilisation and numerous tests and analyses of water and fluids treated in the device in accordance with the above-mentioned technique have shown surprising results, which in most cases display improvements in the quality of water and fluids which have been subjected to a treatment with the device according to the invention.

However, in certain cases it has proved that the otherwise excellent effect of the device according to the known technique has not shown itself, and almost regardless of what improvement has been attempted to be made with the device according to the invention, the otherwise surprising effect obtained in other cases has not been able to be achieved. The conclusion which has been reached is that in all probability the reason can be found in the local relevant installation in which the device is placed, or that there has arisen a very low flow through the device and herewith also the associated installation. For example, with installations with the device in the northern hemisphere it has shown that if the flow in the piping installation in which the device is installed is beforehand a right-hand flow, the sur- prising result is not forthcoming. And neither have attempts to change the direction of the flow through the device, so that this flows to the left, have been able to produce the desired surprising effect in installations in the northern hemisphere. However, the surprising effect arises just as frequently in the southern hemisphere when the spiralling of the guide plate in the device extends in the opposite direc- tion, which has the result that the liquid in its passage of the device is made to flow to the left, but also here the effect is sometimes not produced with installations where the direction of the flow of the water/the liquid is already to the left. Therefore, it is assumed that the treatment of the water or other fluid material can be related to Coriolis force, due to the rotation of the Earth, and it is assumed that the surprising effect in the form of the improvement of quality of water and fluid materials when treated with the device according to the known technique can be based on a compensation principle related to Coriolis force.

It is the object with the invention to provide a device for treatment of water and other fluid materials which is based on the already-known technique, but which ensures that the surprising effect is achieved. A further object of the inven- tion is to provide a device where the surprising effect is also achieved with relatively modest flows through the device and the installation associated herewith.

It is realised that this object can be achieved with a device of the kind disclosed by way of introduction, which is characterised in that inside the straight, tubular element there is provided a shorter, straight, plane, plate-formed piece which is disposed between the first spiralled guide plate and the second spiralled guide plate, so that the ends of the shorter plate piece facing towards the spiralled guide plates stand in extension of and are on a level with the corresponding ends of the spiralled guide plates.

With tests with the device for treatment of water/fluids, the inventor has ascertained that the desired unique effect practically always arises with regard to the quality of water or similar fluid products which are subjected to treatment in a device according to the invention, placed in installations in the northern hemisphere or the southern hemisphere, where the water/fluid has a right-hand/left-hand direction of flow respectively after passage of the device. The reason is that the water/fluid, in its passing of the first passage after the inlet opening with e.g. the right- hand spiralled guide plate, is given a left-hand-directed forwards flow which is stopped by the straight course, whereby the rotation energy which is imparted to the straight flow is converted to a micro-molecular turbulence in the liquid, which with the continued flow of the liquid is immediately changed radically by the passing of the second passage, for example with the left-hand spiralled guide plate, to a right-hand-directed forward flow. There is hereby achieved a macro-molecular turbulence in the liquid combined with a right-hand directed flow of the liquid after passage of the left-hand-spiralled guide plate.

Practical tests with water treated with the device according to the invention have thus shown the following: Water has a tendency to surround micro particles with a complex of loosely bound water molecules. In this complex of bound water molecules, the micro particles are cut off so that they can not crystallise with calcium carbonate (lime), but are instead precipitated on e.g. pipes and heating elements.

With the mechanical water treatment, the water is led through the device according to the invention, whereby it is ensured that the water comes "correctly" into the system regardless of whatever it is that influences the water before it reaches forward to the system.

The exchange activity between right-hand-directed/left-hand-directed flow, straight flow, followed by right-hand-directed/left-hand-directed flow as disclosed above, which arises with the passage of the water through the device according to the invention, brings about a bursting of the molecular composition, so that the surrounded micro particles can stand at disposal for calcium carbonate (lime).

The micro particles will now attract the calcium carbonate molecules. They now collect in clusters and herewith lose the ability to precipitate in pipes and valves, and now flow with the water out of the installation.

At the same time, other materials such as iron and manganese are bound, which can be seen since the colour after iron and manganese disappears at the same time with the splitting of the lime. However, this can not be meas- ured/analysed chemically, since the same materials are still in the water as before the treatment, but it is the composition of the molecules that are found in the water which is different.

In a microscope with great enlargement, it can clearly be seen that the lime has collected in clusters in the water which is treated with the device according to the invention. One can measure a slight increase in the content of salt in the water, and this contributes towards giving the water a better taste.

It is also for reason of the bursting of the molecules that, for example, odours arising in the water/liquids disappear after treatment with the device according to the invention. It can be a chlorine smell after addition of chlorine in the water, but it can also be odours in connection with the reuse of water in industry, and it is often the odours which in most cases are the reason why water cannot be reused. However, if a corresponding device is installed in an installation in the south- em hemisphere, the effect is never realised. But it has shown that if the straight, tubular element comprises at least the two spiralled guide plates, where between these there is a shorter, straight, plane plate-shaped piece, which is disposed between the first spiralled guide plate and the second spiralled guide plate in accordance with the above, but with the difference that the first guide plate, which is placed nearest the inlet end, is spiralled to the left around the longitudinal axis, and where the other, which is placed nearest to the outlet end, is spiralled to the right around the longitudinal axis, with the result that the flow of water/liquid is given a left-hand-directed flow with passage of the device according to the invention, then the desired, surprising effect of the device mounted in an installation in the southern hemisphere will be produced.

Tests have shown that the straight, tubular element can with advantage consist of a pipe with circular cross-section, and that the spiralled guide plates and the shorter straight plate piece can with advantage consist of elongated rectangular plate pieces.

It is preferred that the spiralled guide plates used in the device are spiralled one turn around the longitudinal axis.

However, it can be mentioned further that the first and the second guide plate can with advantage be spiralled around its own axis within the interval 0-359.999° around the longitudinal axis.

Further, it can be mentioned that the first and the second guide plate can with advantage be spiralled around its axis within the interval 360.001-1080°.

Out of regard for ease of installation, the tubular element in the inlet end and the outlet end can comprise connection possibility to the piping installation in the form of an internal or an external thread. This will ease the work with connection of the device/the tubular element to existing and new pipe installations.

With the object of increasing the rate of flow of the water/the liquid which passes through the passages with the guide plates, and with the object of ensuring an effective fastening of the first guide plate on the inlet side, the periphery of the first spiralled guide plate can have a slightly conical extent with greatest diameter nearest the inlet end, and the second spiralled guide plate has a slightly conical extent with greatest diameter nearest the outlet end, and that the straight, tubular element, or lining pipe pieces disposed in this, has a conical extent corresponding to that of the guide plates over the extent in which the first spiralled guide plate and the second spiralled guide plate are housed.

This will result in an improved effect according to the invention, namely by smaller flow through the tubular element. However, there thus remains a solution to the problem concerning the fastening of the guide plate nearest the outlet open- ing, which is not immediately retained. Moreover, it is extremely desirable to make sure that also the guide plate nearest the inlet opening remains in its position.

With the object of increasing the rate of flow of the water/the liquid which passes through the passages with the guide plates, and with the object of ensuring that both the first and the second guide plates are secured, the periphery of the first spiralled guide plate can have a slightly conical extent with smallest diameter nearest the inlet end, and the second spiralled guide plate can have a slightly conical extent with smallest diameter nearest the outlet end. And that the straight, tubular element, or lining pipe pieces placed in this, has a conical extent corre- sponding to that of the guide plates over the extents in which the first and the second guide plates respectively are housed. There is hereby achieved an increase in the flow through the device at the inlet opening and at the outlet opening, and where the rate of flow during passage of the centremost part of the device decreases, with the result that the flow can more calmly be influenced to the oppo- sitely-directed direction of flow (left/right around the longitudinal axis, depending on where the device is installed (northern or southern hemisphere)), at the same time that both the first guide plate as well as the second guide plate and a possibly existing straight, plane guide plate will be secured.

With the object of further ensuring that the first and the second guide plates remain in their respective desired positions in the first passage and the second passage, the straight, tubular element can near the inlet end and the outlet end, or the ends with greatest diameter of lining pipe pieces inserted in the straight, tubular element, can have an annular projection oriented towards the centre axis of the pipe for contact for the retention respectively of the first spiralled guide plate and the second spiralled guide plate.

In a further embodiment of the device according to the invention, the straight, tubular element, or lining pipe pieces placed in this, can further comprise annular projections oriented towards the centre axis of the pipe at the ends of the first guide plate and the second guide plate which face towards each other.

With the object of ensuring a suitable and uniform flow of water/liquid at the inlet end and the outlet end, the end side of the first spiralled guide plate facing towards the inlet end, and/or the end side of the second spiralled guide plate facing the outlet end, can be tapered/bevelled from each side surface towards the centre of said plates.

In a second embodiment of the device according to the invention, the end of the first spiralled guide plate facing towards the inlet end, and/or the end of the second spiralled guide plate facing towards the outlet end can comprise a zigzag angle bend.

Tests have also shown that the effect achievable with a special embodiment of the device according to the invention can be improved by the spiralled guide plates along their centre axes comprising a longitudinal indentation/goove on the one flat side which corresponds to a projection on the other flat side.

In a further embodiment of the device according to the invention, where relatively small flow arises through the straight, tubular element, the shorter plate piece can comprise a number of holes in which there are placed magnets, the length of which at least corresponds to the thickness of the shorter plate piece. There is hereby achieved an influence of the polarity of particles arising in the wa- ter/liquid which passes the device, whereby the ability of these to adhere to the inside walls of the pipes, in washbasins, sinks and other surfaces connected with tapping places is reduced.

The same effect can be achieved if the first spiralled guide plate in the end nearest the second spiralled guide plate comprises a non-spiralled piece in which magnets are placed in a corresponding manner.

Correspondingly, the effect can also be achieved when the second guide plate in the end nearest the first spiralled guide plate comprises a non-spiralled piece in which magnets are placed.

An improved effect with the two latter embodiments of the guide plates can also be achieved when the non-spiralled pieces in the ends of the first and the second ends of the first or the second guide plate comprise a number of holes in which magnets are placed, the length of which corresponds at least to the thickness of the non-spiralled pieces.

With the object of ensuring service easiness in connection with the servicing of the device for the treatment of water or other fluid materials according to the invention, the straight, tubular element can be separated into several parts at water-tight and pressure-tight joints.

With the object of ensuring a uniform course of treatment of the water/liquid which flows through the device, the passages in which the spiralled guide plates are housed can with advantage have the same length.

Depending on the manner in which the device according to the invention is used, including with regard being paid to the amount of water/liquid which shall flow through the passages in the tubular element, and with regard to local conditions in which the device is used, the tubular element can have a length of 0.01mm - 25 m, for example 0.01-0.1mm, 0.1-0.2mm, 0.2-0.3 mm, 0.3-0.4mm, 0.4-0.5mm, 0.5-0.6mm, 0.6-0.7mm, 0.7-0.8mm, 0.8-0.9mm, 0.9-1.0mm, 1-2mm, 2- 3mm, 3-4mm, 4-5mm, 5-6mm, 6-7mm, 7-8mm, 8-9mm, 9-10mm, 1-2cm, 2-3cm, 3- 4cm, 4-5cm, 5-6Cm₁ 6-7cm, 7-8cm, 8-9cm, 9-10cm,10-20 cm, 20-30 cm, 30-40 cm, 40-50 cm. 50-60 cm, 60-70 cm, 70-80 cm, 90-100 cm, 1-2 m, 2-3 m, 3-4 m, 4- 5 m, 5-6 m, 6-7 m, 7-8 m, 8-9 m, 9-1O m, 10-11 m, 11-12 m, 12-13 m, 13-14 m, 14-15 m, 15-16 m, 16-17 m, 17-18 m, 18-19 m, 19-20 m, 20-21 m, 21-22 m, 22-23 m, 23-24 m, 24-25 m.

Depending on the manner in which the device according to the invention is used, including with regard being paid to the amount of water/liquid which shall flow through the passages in the tubular element, and with regard to local conditions in which the device is used, the length of the first and the second spiralled guide plate can be between 0.005mm-12m, for example 0.005-0.01 mm, 0.01- 0.1mm, 0.1-0.2mm, 0.2-0.3 mm, 0.3-0.4mm, 0.4-0.5mm, 0.5-0.6mm, 0.6-0.7mm, 0.7-0.8mm, 0.8-0.9mm, 0.9-1.0mm, 1-2mm, 2-3mm, 3-4mm, 4-5mm, 5-6mm, 6- 7mm, 7-8mm, 8-9mm, 9-10mm, 1-2cm, 2-3cm, 3-4cm, 4-5cm, 5-6cm, 6-7cm, 7- 8cm, 8-9cm, 9-10cm, 10-20 cm, 20-30 cm, 30-40 cm, 40-50 cm. 50-60 cm, 60-70 cm, 70-80 cm, 90-100 cm, 1-2 m, 2-3 m, 3-4 m, 4-5 m, 5-6 m, 6-7 m, 7-8 m, 8-9 m, 9-1O m, 10-11 m, 11-12 m.

In the cases where the device comprises a straight plate piece between the first guide plate and the second guide plate, it is preferred that the straight plate piece between the first and the second spiralled guide plate has a length which lies within the interval of 5-40% of the length of a relevant spiralled guide plate.

With the object of ensuring quick and easy service and assembly in the mounting and servicing of the device for treatment of water or other fluid material according to the invention, where the tubular element in the inlet end and in the outlet comprises possibilities of connection to the piping installation in the form of an internal thread, the device can comprise flats for engagement of a spanner/key.

As described above, the device according to the invention is assumed to function on the basis of a compensation principle based on Coriolis force. How- ever, this approach for the understanding of the technical effect shall not be understood has a limiting method for the invention. It is further assumed that the surprising effect with the use of the device according to the invention is not based on strictly chemical or material-related effects, and therefore it is assumed that the tubular element, the lining pipe pieces, the first and the second spiralled guide plates and the straight plate piece, can with advantage be made of metal such as iron, galvanised iron, steel, and namely in stainless steel, aluminium, copper, silver, gold, or other corrosion-proof material, or combinations hereof, or of plastic material such as PVC, PP, ABS, POM or the like, and that the tubular element, the guide plates and the straight plate piece can also be made of identical materials or of different materials.

The invention also relates to a method for the treatment of water or other fluid material, comprising a device for treatment of water or other fluid material, and comprising a straight, tubular element with an outer wall which defines a through- going passage with an inlet end and an outlet end with a longitudinal axis, and a first elongated guide plate and a second elongated guide plate placed in the through-going passage, where said guide plates are spiralled with mutually oppo- site convolutions in relation to/around said longitudinal axis, and where said guide plates can be housed in said through-going passage for the dividing of this into at least two parts for the guiding of water or other fluid material along said divisions of said passage from the inlet end to the outlet end, where the straight, tubular element comprises at least two passages with spiralled guide plates, where inside the straight, tubular element there is provided a shorter, straight, plane, plate- shaped piece which is disposed between the first spiralled guide plate and the second spiralled guide plate, so that the ends of the shorter plate piece facing towards the spiralled guide plates stand in extension of and are on a level with the corresponding ends of the spiralled guide plates, mounting of the device on a wa- ter installation or a supply installation for other fluid material, for passage of water or other fluid material through the straight, tubular element, for treatment of water or other fluid material by leading the water respectively along the first spiralled guide plate and along the second spiralled guide plate, mounting of the device on a water installation or a supply installation for other fluid material, for passage of water or other fluid material through the straight, tubular element for treatment of water or other fluid material by leading the water respectively along the first spiralled guide plate and along the second spiralled guide plate.

In fig. 1 there is shown a side cross-sectional view of a first embodiment of a device 2 for treatment of water/liquids according to the invention. The device 2 comprises two pipe pieces 4, 6 which are connected together by a pressure-tight and water-tight threaded joint 8. Housed inside the pipe 4 there is seen a first spiralled guide plate 10 in a first passage 11 which begins at the inlet opening 12, and a second guide plate 14 in a second passage nearest the outlet opening 16. The first guide plate 10 is spiralled approximately but not completely a whole con- volution to the right in relation to the longitudinal axis 18 of the pipe, and in relation to the direction of flow as indicated by the arrow A. The second guide plate 14 is spiralled approximately but not completely a whole convolution to the left in relation to the longitudinal axis 18 of the pipe, and in relation to the direction flow as indicated by the arrow A. The guide plates are in contact with the walls of the pipe and thus divide the passages 11 and 15 into two equally large parts. This will mean that a liquid flow which extends in the first passage 11 will be given a left- hand-directed flow by the first guide plate 10, after which the flow will immediately continue further in the second passage 15, where it will be given a right-hand- direction of flow by the second guide plate, after which the flow continues out through the outlet opening. The liquid will hereby be activated so that its content of lime and other material particles will not adhere/precipitate in the subsequent piping installation, or in the washbasins or sinks or shower rooms at subsequent tapping stations in the installation, cf. fig. 9.

As will also appear in fig. 1 , at the inlet opening 12 and the outlet opening 16 the pipe pieces 4, 6 respectively comprise threaded surfaces 20, 22 for mounting of the device for treatment of water/liquids according to the invention. In fig. 2, which is an end view of the device shown in fig. 1 , it is seen that the ends with the threaded surfaces 20, 22 comprise flat surfaces 24 to accommodate a spanner/key, which will ease the mounting and service of the device 2.

In fig. 3 there is shown a side view of an embodiment of a device 2 for treatment of water/liquids according to the invention, where the pipe 3 is provided an external thread 26, and fig. 4 is a cross-section of a threaded adapter 28 with internal threaded surfaces 20, 22 for the device shown in fig. 3.

Fig. 5 is a cross-section of a lining pipe piece 30 with an internal conical cross-section for building into the device shown in fig. 3 for the treatment of water/liquids according to the invention. As will appear in fig. 14, the threaded adapter 28 comprises an internal threaded surface 32 which cooperates with the external thread 26 on the device 2. As will also be seen, the internal diameter of the threaded adapter 28 is slightly smaller than the internal diameter of the pipe 3 which comprises part of the device 2, which means that in its mounted position in the ends of the pipe 3 the adapter 28 will secure a lining pipe piece 30 as shown in fig. 5 in position in the pipe 3.

Fig.6 shows a side view of a first embodiment of a spiralled guide plate 10^' spiralled to the right around its own axis 34, which is associated with a second embodiment of the device 2 for treatment of water/liquids according to the invention. As will be seen, the one end of the guide plate 10^' has a zigzag-formed extent 36.

In fig. 7 there is shown a side view of a second embodiment of a spiralled guide plate 10^" spiralled to the right around its own axis 34, which is associated with another embodiment of the device 2 for treatment of water/liquids according to the invention. Here, the one short side edge 38 of the guide plate 10^" is pro- vided with a taper/bevelling 40 extending from each side of the guide plate towards its centre, thus providing a sharp edge 42.

In fig.8 there is shown a side view of a third embodiment of a spiralled guide plate 10'" associated with a further embodiment of the device 2 for the treatment of water/liquids according to the invention. Here, the one end of the spiralled guide plate 10^'" has a non-spiralled part 44 comprising holes 46 in which magnets 48 are placed. In fig.9 there is shown an example of how a device 2 for the treatment of water/liquids according to the invention is built into a straight piece of a piping between a water meter 52 and a tapping point 54 in an installation 50 for the supply of water.

In fig. 10 there is shown a cross-section of a conical guide plate 10"^" built into a lining pipe piece 30 with conical internal extent cf. fig. 12, and with an internal annular projection 56 for securing the conical spiralled guide plate 10"^", which is mounted in the conical section by the pressing of the end 58 of the guide plate 10^"" in passed the projection 56, whereby the guide plate 10"" is secured.

Fig. 11 shows a side view of the conical spiralled guide plate 10"^" shown in fig. 10.

Fig. 12 shows a side sectional view of a lining pipe piece 30 with internal conical section and an internal annular projection 56 for securing the conical spiralled guide plate 10"" for placing in a pipe 3, as will appear in fig. 13 and 14.

In fig. 13 there is shown a side sectional view of a device 2 for treatment of water/liquids according to the invention with a short, straight plate piece 60 placed between the two spiralled guide plates 10^"", 15^"", and with internal annular projection in the lining pipe 30 with conical extent, placed in a pipe 3. As will also appear from the figure, in the one end the lining pipe piece 30 is secured by a threaded adapter 38 which comprises an internal thread 20 on the inlet side 12. It is also seen how the ends of the lining pipe pieces with the largest diameter 30 face towards each other, and where the annular projection 56 ensures that the guide plates 10^"", 15^"" and 60 maintain their mutual positions.

In fig. 14 there is again shown a side sectional view of a device 2 for treat- ment of water/liquids according to the invention, this time with a longer, straight plate piece 62 placed between the spiralled conical guide plates 10"", 15"^" placed in pipe 30 with conical extent. Here, the lining pipe pieces 30 and herewith the guide plates 10^"", 15"" secured by being fixed between the threaded adaptors 28 (only the one is shown) which comprises an internal thread 20 on the inlet side 12. Fig. 5 shows a section of an embodiment of a device 2 for treatment of water/liquids according to the invention, where the spiralled guide plate 10 has a longitudinal indentation/groove 64 along the centre axis 18.

In Fig. 16, which is an enlarged cross-section of the guide plate 10, it is seen how the indentation/groove 64 on the one side of the guide plate 10 corresponds to a projection 66 on the other side of the guide plate 10. The indentation/groove 64 and the projection 66 contribute towards providing a more parallel-oriented process of flow around the guide plate 10.

In Fig. 17, the devices 2 according to the invention are shown mounted in supply pipes 102, 104, 106 for each of the washing machines 108, 110, 112 in a laundry 100, where the inlet flow is not great with these types of machines. The devices provide savings in service and the consumption of washing powders, which ultimately results in lighter loads on the environment.

In fig. 18 the device 2 according to the invention is seen combined with a circulation system 20 comprising a pump 122 which circulates water in a vessel 124 via the device according to the invention. The water is supplied to the pump 122 via a pipe 126 in the bottom of the vessel, and is pumped via a pipe 28 via the device 2 back to the vessel 124. The system comprising the device according to the invention has proved to have a positive effect, for example on pig farms and poultry farms, where the effect from the system manifests itself by a reduced smell of ammonia from the farms, the reason being that the water treated with the device 2 according to the invention binds the ammonia due to the finer, degradation of the molecular structure of the minerals in the water. Moreover, this has the positive effect in the form of a reduced frequency of sores on the animals' footpads, and herewith improved well-being.

The effect of the device 2 according to the invention can also be ascertained on water valves which are not blocked by particles of lime. This is because the precipitation of lime particles in the water after passage of the device 2 according to the invention is considerably reduced. Moreover, the growth of algae in water troughs is also reduced, which leads to a reduction in the work of removing slime which can otherwise provide breeding ground for bacteria in the drinking troughs.

A short time can elapse before the effect of the device 2 according to the invention becomes optimal, since the systems must first be cleaned of lime. In fig. 19 there is seen a device 2 according to the invention mounted in a washing plant 130 for automobiles, where up to 85% of the water is reused, in that the water which is circulated from the washing plant allows itself to be cleaned af- ter passage of the device 2.

The plant comprises a pump 132 in a pump well 133 from which water 134 for reuse is pumped via the device 2 to a pressure filter 136 which cleans the recycled water. The now cleaned recycled water is hereafter reused for brush wash- ing by the washing machine 138, after which via an outlet pipe 140 it is fed back to the well 133.

Clean water for the replacement for the water which the cars (not shown) lead away from the system is fed to the washing plant 130 by the rinsing of the car (not shown) with clean water from a clean water supply pipe 142. This water is fed to the washing plant via a device 2 according to the invention in order to eliminate the precipitation of lime present in the clean water supply, which is fed to the washing machine 138 via a changeover valve 144 and via pipe 146. The water runs back from the washing machine to the pump well 133 via a drain 148, after which it is reused.

There is also a great effect to be seen in the recycled water before and after the treatment if there is no filter, the precipitation is strongly increased by the treatment, the particles are collected together and become heavier at the same time that the carrying capacity in soft water is less so that it provides a very quick clearing of the water.

It can immediately be measured in that one shall empty sand trap with shorter intervals than before the system was mounted.

In fig. 20 the device according to the invention is seen mounted in another embodiment of a washing plant 130' for automobiles. Water 134 for reuse lies in a pump well 133 from which via a pump 132 it is fed to a high-pressure pump 150, which via the device 2 according to the invention leads the water further under pressure via a high-pressure pipe 152 to a rinsing plant 154 for rinsing of the undercarriage. Lime and odours are hereby removed from the pressure water before this is fed to the rinsing plant, with the result that odours do not arise in the room in which the washing plant is installed. Moreover, lime does not precipitate on the automobiles (not shown) which are washed in the washing plant 130'. The supply pipe 142 for clean water is similarly provided with a device 2 according to the invention with the object of eliminating the precipitation of lime on the automobiles which are washed in the washing plant 130.

In a washing plant for automobiles in which a device 2 according to the invention is mounted, in some cases it has shown that the recycling part of a washing plant is able to function and be taken into use after a pause of long duration, as a consequence of the odours connected with the reuse of the water after installation of the device 2 being eliminated, which has resulted in a saving in the consumption of clean water of 1 ,300 m3 over a period of approx. 6 months.

In another washing plant for automobiles, a corresponding problem arose with odours from the plant^'s recycling part, where attempts to eliminate this prob- lem were made without success with various chemicals and mechanical arrangements. After the mounting in the plant of the device 2 according to the invention, the odours were eliminated and the colour of the recycled water was changed from being very cloudy to appear as clear.

In a third washing plant for automobiles, where around 35-40,000 cars were washed annually, and where it was necessary to undertake daily manual cleaning of that part in which a car washing plant was installed in order to keep its floors, walls and windows free from the adherence of lime deposits and dirt, the installation of the device 2 according to the invention resulted in the frequency at which cleaning was necessary being able to be reduced to once weekly. Moreover, also here it was observed that odours arising from the reuse of water disappeared, and stoppages of rinsing nozzles and pipes as a result of lime deposits were also eliminated, Moreover, the number of cars washed increased after approx. 1 month, the reason being that the customers observed that precisely this washing plant did not leave lime deposits following evaporated drops of water on the lacquer of their cars. Consequently, as a result of the installation of the device 2 according to the invention, there was achieved a reduction in the cleaning costs and maintenance of the relevant washing hall to a seventh part, and an increase in the turnover of the plant.

In fig. 21 the device 2 according to the invention is shown mounted in a waterworks. The device is seen in the supply side 162 for raw water, where this is provided with a filter 160. After passage of the filter 164, the water is fed to an ac- cumulation tank 166, from which by high-pressure pumps 168 and via pressure pipe 170 provided with the device 2', the water is pumped out to the consumers. There is hereby achieved that a precipitation of lime in the waterworks' filter plant and piping system out to the consumers is eliminated.

Fig. 22A and 22B show examples of water samples taken from the same locality respectively before and after the device is mounted in a water treatment plant, where the device according to the invention is mounted.

The water sample shown in fig. 22A is taken before the installation in a water installation of the device 2 according to the invention, and here the content of particulate materials 172 suspended in the water can clearly be seen. In fig. 22B is seen a sample of water taken from the same place after the device 2 according to the invention is mounted in the same water installation, where the water is quite clear and transparent.

Fig. 23A and 23B show examples of water taken from the same locality respectively before and after the device 2 is mounted in a water installation after standing for 24 hours. Here, a "cloud" 174 of particulate material can still be seen in the water sample to the left, fig. 23A, while the water sample in fig. 23B to the right is clear and transparent.

With the effect of the device 2 according to the invention, with regard to the reduction/elimination of lime precipitation, it will be obvious to use the device in all places where the risk of lime precipitation arises. This can be in water installations, heat exchangers, heating elements and boilers, both within industry and the shipping trade as well as in private homes, where considerable savings in costs can be achieved in the maintenance and replacement of said components, and valves and nozzles in connection herewith.

The device 2 according to the invention distinguishes itself in being able to handle all kinds of flow, even in places where other systems can not solve the problem, and the system has a long lifetime and is not affected by external influences. It can be used in large industrial concerns where it is possible to solve the problems with lime precipitation in piping system etc., and at the same time the water can be used as drinking water. This means that in these localities it is possible for the establishing of two-string plants to be avoided, one for process water and the other for the supply of drinking water. Moreover, drinking water which tastes better is achieved due to the salt balance being raised slightly, and the water becomes odour-free.

The inventor has naturally realised that the invention can assume configura- tions other than those shown in the drawing and as described above, but this does not change the innovative aspect, which consists in a significantly more reliable function of the device 2, regardless of whether this is mounted in an installation which already has a right-hand-directed course of flow in the northern hemisphere, or a corresponding already left-hand-directed flow in the southern hemisphere, in that the flow of liquid by passage of the device 2 according to the present invention at the inlet opening and the passing of the first passage 11 is given an oppositely- directed in relation to the preferred, after which the liquid flow in connection with the passage of the shorter straight, plane plate-shaped piece (60, 62), which is disposed between the first spiralled guide plate (10) and the second spiralled guide plate (14), where the rotation energy induced in the liquid is converted to a micro-molecular turbulence in the liquid, and a subsequent leading of the flow of liquid along the second guide plate 14 in the second passage 15, is influenced in the direction of the preferred course of flow for the relevant localising (northern hemisphere - right-hand-directed flow or southern hemisphere -left-hand-directed flow) at the outlet side 16. The are hereby achieved greatly improved characteristics of the liquid which has passed the device according to the invention, such as for example that deposits of lime do not arise in piping systems in water installations, that materials suspended in water which has passed the device according to the invention is more readily precipitated, and that possible odours from liquids which have passed the device according to the invention are not released to the surroundings.
