The present invention relates to ionic polarization unit for physical treatment of water with increased efficiency, intended for physical treatment of water in closed and open systems in particular in order to prevent the formation of limescale in heat exchangers, cooling systems, boilers, condensers, drinking water and industrial water distribution facilities, etc.

Prior Art:

In the prior art there is a number of known devices, which engage in ionic polarization of fluids, e.g. UV 892, UV 4881 and UV 7053, which disclose ionic polarization unitsfor treatment of water and are the development series of one inventor. The units comprise a flow vessel with inlet and outlet orifices, inside of which there are at least twoelectrodes made of different electrically conductive materials and having various shapes; individual solutions are focused on improving the efficiency, whether it is by increasing the surface areas of the electrodes, or by adding additional electrode segments with different conductivity. Ion Scale Buster device for galvanic water treatment is also known; inside the device there is a clean zinc anode fitted in a brass socket and Teflon chambers connected in series. This device with water form a galvanic cell, which releases a minute amount of zinc, which consequently supports the agglomeration of substances present in the water.

Substance of the Invention:

The substance of the invention lies in ionic polarization unit for physical treatment of water with increased efficiency on galvanic principle, which comprises the inlet orifice, which is watertightly connected to one end of the tube made of dielectric material, inside of which there are alternately located polarization electrodes made of sheet metal in a form of spirals; each of which is made of a different type of electrically conductive material, such asaluminum, brass, zinc, copper, silver, titanium, platinum or alloys thereof. In front of and/or behind and/or in between the electrodes, there may be installed at least one fixed or moveable insulation through- flowdi stance ring, which is made of dielectric material, such as plastics or ceramics, and is in form of a collar comprising on its inner perimeter fixed distribution blades not exceeding the width of the collar, which are mounted at an angle of 15° - 85°relative to the transverse axis of the collar. Insulation through- flowdi stance rings make sure, there aren't any conductive connections between the electrodes and at the same time they regulate the water flow and cause its spiral, helical course.

Since the capacity of galvanic cellalso depends on the surface areas of electrodes, they have been designed to ensure that the surface area, which is flown around by the flowing water, is as large as possible and at the same time to put up as little resistance as possible leading to a low pressure loss of the device.

These electrodes are made of sheet metals and have several variations. The above devices are advantageous in low production costs and in large capacity of galvanic cells.

Since the dimensions and consequently the surface areas of the electrodes are limited by the dimensions of the construction, the efficiency can be improved only by lengthening the path of water flowing around the surface areas of individual electrodes. This is achieved by the fact that the insulation through-flowdi stance rings installed in front of and/or in between and/or behind the electrodes are made of dielectric material and the fixed distribution blades located insidethe insulation through-flowdi stance rings cause that the flow of the flowing water is not linear, but has a helical, spiral shape along the surface areas of the electrodes and hence the contact of the flowing water with the surface areas of polarization electrodes is several times larger.

Examples of Embodiments

Ionic polarization unit for physical treatment of water with increased efficiency comprises the inlet orifice J_, which is watertightly connected to one end of the tube 2 made of dielectric material, inside of which there are alternately located at minimum two polarization electrodes 3 made of sheet metal in a form of spirals; each of which is made of a different type of electrically conductive material, such asaluminum, brass, zinc, copper, silver, titanium, platinum or alloys thereof. In front of and/or behind and/or in between the polarization electrodes 3, there is at least one fixed or moveable insulation through-flowdi stance ring 7, which is made of dielectric material, such as plastics or ceramics, and is in form of a collar comprising on its inner perimeter fixed distribution blades 8 not exceeding the width of the collar 9, which are mounted at an angle of 15° - 85°relative to the transverse axis of the collar 9. Insulation through-flowdi stance rings 7 make sure, there aren't any conductive connections between the polarization electrodes 3 and at the same time they regulate the water flow and cause its spiral, helical course. The outlet orifice 5 is connected to the piping 6.

Since the dimensions and consequently the surface areas of the polarization electrodes 3are limited by the dimensions of the construction, the efficiency can be improved only by lengthening the path of water flowing around the surface areas 4 of individual polarizationelectrodes3. This is achieved by the fact that the insulation through-flowdi stance rings 7installed in front of and/or in between and/or behind the polarization electrodes 3 are made of dielectric material and the fixed distribution blades 8 located insidethe insulation through-flowdi stance rings 7 cause that the flow of the flowing water is not linear, but has a helical, spiral shape along the surface areas 4 of polarization electrodes 3 and hence the contact of the flowing water with the surface areas 4 of polarization electrodes 3 is several times larger.
