Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention applies an electric field or a magnetic field to the generation of scale that causes various troubles when attached to the inner wall of a water channel pipe in a circulating water system such as a cooling circulating water channel or a boiler or a flowing water system. The present invention relates to a water treatment device for prevention.

[0002]

2. Description of the Related Art Generally, in a circulating water system for cooling, a circulating water system such as a boiler, or a running water system, scale is gradually generated due to long-term use, which causes various troubles such as adhesion to the inner wall surface of the waterway. cause. For example, the scale adheres to a heat transfer surface or a pipe in a heat exchanger incorporated in a circulating water system pipe or the like, which causes deterioration of heat exchange efficiency, blockage of the pipe, generation of rust, and the like. In response to this, a water treatment device has been developed that prevents the generation of scale by applying an electric field or magnetic field to circulating water.
Electrodes having different electrochemical potentials are installed opposite to each other so as to sandwich the water passage, an electric field is applied to circulating water between these electrodes (Japanese Patent Laid-Open No. 63-39690, etc.), or a permanent magnet is used in combination with the electrodes installed facing each other. However, a device for applying an electric field generated by these electrodes and a magnetic field generated by a permanent magnet (Japanese Patent Laid-Open No. Hei 5)
-57286, etc.) has been proposed.

According to the above method, the scale component contained in the circulating water receives the action of an electric field or a magnetic field, grows as crystals instead of becoming scale, and moves in a floating state together with the circulating water. Since the crystals are deposited as sludge on the bottom of the tank in the circulating water system, etc., it is possible to prevent the generation of scales by collecting the sludge. According to the research conducted by the inventors of the present application, it is effective to connect an external resistor between electrodes so that a weak current flows between the electrodes when applying an electric field, and to apply a magnetic field force to this. It has been found to be more effective.

[0004]

However, since the above-mentioned device is used after being cut in the middle of the pipe of the water circulating device or the like and installed in the water circulating device by providing a bypass or the like, the water treatment is newly performed. When installing a device or repairing or replacing a water treatment device, there is a problem that the operation of the water circulation device or the like must be stopped. The present invention
It was made against the background of the above circumstances, and can be easily incorporated into a water circulation device or the like. For example, by connecting it to the end of a pipe of the water circulation device or the like, it can be incorporated without stopping the operation of the circulation device or the like. It is an object of the present invention to provide a water treatment device which is capable of exhibiting excellent water treatment capacity.

[0005]

In order to solve the above problems, in the water treatment apparatus of the first invention of the present invention, at least two treated water passage ports are formed on the wall surface of the closed hollow body. In the inside of the hollow body, a partition for partitioning the hollow body internal space into a continuous water passage is provided so that both of the plurality of treated water passage ports are in communication on the water inlet side and the other is on the water outlet side. Different materials are arranged on at least a part of wall surfaces facing each other across the water channel.

Further, in the water treatment apparatus of the second invention, in the first invention, magnetic poles having different polarities are opposed to each other so as to sandwich a water channel sandwiched by different materials in a direction intersecting with a facing direction of the different materials. It is characterized by being arranged. 3rd invention is a 1st or 2nd invention, Comprising: A hollow body consists of a cylindrical body which has a bottom plate at both ends, and the treated water passage opening is provided in the bottom plate center part of this cylindrical body, and the wall surface by the side of a periphery, respectively. It is provided, and a partition wall provided along the axial direction is provided inside the tubular body.

The water treatment apparatus of the present invention can be applied not only to a circulating water system for cooling or a circulating water system such as a boiler, but also to a running water system in which water does not circulate. Further, the water treatment device of the present invention may be arranged at any position of the circulating water system or the flowing water system, for example, directly connected to the end portion of the circulating water system pipe (whether the water outlet or the inlet). You can In such a water treatment device incorporated in a circulating water system, etc., water is introduced from a part of the treated water passage port, treated to this water, and then the other treated water passage port is circulated to a circulating water system or a running water system. It can be returned or drained as it is.

The shape of the hollow body which constitutes the water treatment device is not particularly limited, but it is preferable that the hollow body is constituted by a cylindrical body having a closed structure, and the treated water can flow in and out at the central portion and the peripheral portion of the cylindrical body. Is desirable. As a result, the water flow is largely deflected, so that the water and the different materials come into good contact with each other, and the water treatment efficiency is improved. The partition wall provided inside the hollow body is
It is provided according to the shape of the water channel secured inside the hollow body. In the above-mentioned tubular hollow body, it is desirable to arrange a partition wall along the axial direction, for example, a cylindrical partition wall or a spiral partition wall concentric with the hollow body to secure a concentric ring-shaped or spiral water channel in the hollow body. As a result, the water flow smoothly flows, the pressure loss can be reduced, and the water channel length can be sufficiently obtained, so that the water treatment efficiency can be improved.

Dissimilar materials are arranged on at least a part of the wall surface composed of the partition wall and the hollow body wall with a water channel interposed therebetween. The dissimilar material may be arranged by fixing the dissimilar material to the wall surface, or the corresponding wall itself may be made of the dissimilar material in order to more easily dispose the dissimilar material. Further, the dissimilar material may be disposed on at least a part of the wall surface as described above, but it is also possible to dispose the dissimilar material on all of the opposing wall surfaces, and the dissimilar materials may be disposed opposite to each other at a plurality of locations. You can also The point is that it can be arranged so that water can be effectively treated.

As the above-mentioned different material, a conductive material which becomes relatively base and noble due to different electrochemical potentials is used. Therefore, the material and the combination thereof are not limited to specific ones, and, for example, Al, Ti, Zn, Pb or the like can be used as the base material, and carbon, Pt, stainless steel can be used as the noble material. Steel or the like can be used. By arranging the materials facing each other and electrically connecting them to the outside or the like, an electric current flows in the gap between the materials with one as an anode and the other as a cathode to promote crystallization of scale components in water. The connection may be made by using a hollow body wall or a partition wall. However, if the connection is made through an external resistance, the current value between the electrodes can be appropriately changed by selecting the resistance value of the external resistance.

It is also possible to dispose a pair of magnetic poles together with the above-mentioned different material in a water channel including a treated water passage, and in that case, magnetic poles of different polarities are arranged to face each other with the water channel sandwiched therebetween. This magnetic pole can be made to appear by using a permanent magnet or an electromagnet. What is essential is that the magnetic pole can appear at a desired position, and its means is not limited to a particular one.
When the pair of magnetic poles are installed to face each other and the treated water is flown in the gap, an induced current is generated between the magnetic poles by the Hall electric field due to the water flow, and the scale is prevented from being generated similarly to the electric current due to the electric field. By arranging the pair of magnetic poles so as to face each other in a direction intersecting with the facing direction of the electrodes, it is possible to generate an induced current in the same direction as or a direction opposite to the electric field between the electrodes, and synergistically or destructively change the strength of the electric field. . The shape, the number, and the arrangement position of the magnetic poles are not particularly limited and can be appropriately determined. However, in order to perform the water treatment efficiently by adjusting the strength of the electric field appropriately, it is preferable to dispose the magnetic poles so as to face each other in a direction intersecting with the different materials with a common water channel sandwiched between the different materials and the magnetic poles as described above. desirable.

A sludge receiver may be provided in the water treatment device. The sludge receiver can be provided at a position facing the running water so that the sludge can be deposited downward. As a result, it is not necessary to provide a sludge recovery device or the like in the water circulation device, which makes it easier to install the water treatment device.

[0013]

That is, according to the water treatment apparatus of the present invention, it has the treated water passage port on the water inlet side and the treated water passage port on the water outlet side, so that water can be easily introduced from the equipment to be treated. Further, it can be returned to the device or the like. In the water treatment device, a water channel is formed from the treated water passage opening on the water inlet side to the treated water passage opening on the water outlet side, and water flows along the water passage. Dissimilar materials or magnetic poles having different polarities are arranged in this channel, and an electric field or a magnetic field acts on flowing water to promote crystallization of scale components. The crystallized scale component floats in running water and accumulates as sludge at a place where the flow velocity is slow. This sludge can be removed as appropriate. These actions can prevent the occurrence of scale.

DETAILED DESCRIPTION OF THE INVENTION An embodiment of the present invention will be described below with reference to the accompanying drawings. The water treatment device 1 has a cylindrical body 2 having bottom plates at both ends as a main body, an aluminum plate 3 is fixed to a lower surface of an upper bottom plate 2a, and a carbon plate 4 is fixed to an upper surface of a lower bottom plate 2b. 4 is facing. Further, a treated water passage port 5 for entering water is formed in the central portion of the upper bottom plate 2a of the cylindrical body 2, while a treated water passage port 6 for outgoing water is formed on the peripheral wall of the cylindrical body 2. In addition,
A tubular stand-up wall is formed at the periphery of the treated water passage port 5 for entering water, and the stand-up wall serves as the pipe connecting portion 7.

On the other hand, a cylindrical partition wall 8 is provided inside the cylindrical body 2 so as to be continuous with the pipe connecting portion 7, and the partition wall 8 is in contact with the upper and lower bottom plates without a gap. In addition,
A communication port 8a is formed in the partition wall 8 on the side opposite to the treated water passage port 6, and a water passage extending from the central portion of the cylindrical body 2 to the inner peripheral edge is formed, and the treated water is passed through the water passage. Passage 5
And the treated water passage 6 communicate with each other. Further, in the communication port 8a and the treated water passage port 6, permanent magnets 9a, 9b and permanent magnets 10a, 10b, which form a pair so as to sandwich the water channel from the lateral direction, are arranged so as to face each other. On the other hand, the S pole appears on the inner surface (the surface facing the pair of permanent magnets) of the permanent magnets 9a, 10a located on the right side,
The N poles appear on the inner surfaces (the surfaces facing the pair of permanent magnets) of the permanent magnets 9b, 10b located on the left side with respect to the water flow direction, and the magnetic poles of different polarities face each other. A circular hole 2c is formed along the inner wall of the partition wall 8 at the center of the lower bottom plate 2b.
Is formed, and the lower bottom plate 2b is formed so as to close the round hole 2c.
A sludge receiver 11 having a bottomed cylindrical shape is removably attached to the bottom of the sludge. The bottom surface of the bottom of the sludge receiver 11 is provided with a knob 11a that is gripped when the sludge is removed.

Next, a method of using the water treatment device will be described. A pipe connecting portion 7 is connected and fixed to an end portion of a pipe (not shown) of a water circulating device or the like without a gap, and a treated water passage port 6 for water discharge is directed toward a planned water outflow direction. When water flows into the end portion of the pipe, the water flows into the cylindrical body 2 from the treated water passage port 5 of the pipe connecting portion 7, and the center of the cylindrical body 2 is along the water passage separated by the partition wall 8. Flow from the portion to the ring-shaped inner peripheral portion through the communication port 8a (arrow), and finally discharged from the treated water passage port 6 (arrow). While the water flows through the water channel, the water flow is always sandwiched between the upper aluminum plate 3 and the lower carbon plate 4. Therefore, when the water is filled in this space, the aluminum plate 3 is used as the anode and the carbon plate 4. As a cathode electrode, a weak current flows in the water between them. Further, the communication port 8a and the treated water passage port 6 where the magnetic poles of different polarities face each other.
Magnetic field is generated between the magnetic poles, and when water passes through the magnetic field, a Hall electric field is generated in the same direction as the electric field, and an induced current flows. By the action of these electric field and magnetic field, the scale component contained in water becomes a nucleus of the crystal and grows as a crystal while flowing in the circulating water system.

Since a sludge receiver 11 having a cylindrical shape with a bottom is arranged on the inflow front side of the treated water passage port 5 into which water flows, the flow velocity decreases near this and the wall surface of the sludge receiver 11 is reduced. Scale components easily collide. The water treated by the electric field as described above is treated again by the water treatment device 1
When it flows in, the scale component gradually accumulates as sludge on the bottom of the sludge receiver 11 due to the phenomenon near the sludge receiver 11. This sludge can be easily removed from the water treatment device 1 by removing the sludge receiver 11 from the cylindrical body 2, and effectively and efficiently prevents scale from being generated in the circulation device or the like.

In this embodiment, the Hall electric field due to the magnetic poles is made to be in the same direction as the electric field due to the different materials so that the electric field acts synergistically on the water. However, the action direction of the electric field is changed to cancel the electric field. It can also be activated. Further, in this embodiment, the electrode and the magnetic pole are used in combination, but the present invention may use only the electrode. Also,
In the above-described embodiment, the water treatment device is connected to the end of the pipe from which water is flowing out, but it is also possible to connect the water treatment device to the middle of the pipe or the like, allow the water to flow in, and then set the pipe back to the pipe. is there.

Further, in the above-mentioned embodiment, the partition wall is arranged in a cylindrical shape to form the ring-shaped water channel, but the shape of the water channel can be appropriately changed. For example, as shown in FIG. 6, it is possible to arrange the partition walls 16 in a spiral shape to form a spiral water channel. By thus forming the water channel in a spiral shape, the flow of water can be made smooth and the pressure loss can be reduced.
