Description

  The present invention relates to a water treatment apparatus for performing a magnetic treatment on water to be treated and a purification treatment on the treated water to obtain treated water subjected to these treatments.

  Various impurities are mixed in tap water and well water used in factories and the like. In recent years, the demand for removing impurities from water has become stronger with increasing awareness of health and precision of machinery. Various filters have been developed from such a request. For example, in Japanese Utility Model Publication No. 63-63874 (Patent Document 1), a non-woven fabric layer having a specific thickness is provided on the outer periphery of a pipe member having a through hole. Further, there has been proposed a filtration filter provided with a thread body layer in which a thread body is wound with a specific thickness on the nonwoven fabric layer. However, such a filter has not been sufficiently capable of removing impurities.

  On the other hand, there is a problem that water scales (scales) adhere to the inside of a bathtub, water pipe (well water pipe), or any place where water contacts such as a cooling tower or a heat exchanger. The generation of water stains not only detracts from aesthetics, but also makes it difficult for water to flow through water pipes (well water tubes), and reduces the functions of various facilities such as cooling towers and heat exchangers.

In addition, if water stains adhere to parts that are out of reach, such as the inside of the pipe or inside the apparatus, it is difficult to remove the water stains. Therefore, there is a problem that the life of various facilities is shortened due to the gradual adhesion of water. Furthermore, even if the water red removal operation itself is an easy part, the water red removal cannot be easily removed. Therefore, there is a problem that the removal operation takes a long time.
Japanese Utility Model Publication No. 63-63874

  In view of such a current situation, the present invention provides a water treatment device capable of supplying treated water that can obtain water filtration (scale) and can remove water red, while providing an excellent filtration effect. The purpose is to do.

The water treatment apparatus according to the present invention includes a water treatment chamber 13 in the upper part of a substantially cylindrical casing 12 that is long in the vertical direction, a water storage chamber 14 in the lower part, and the water treatment chamber 13 has water to be treated. A water treatment device 10 comprising a magnetic treatment unit 20 for performing magnetic treatment and a water purification unit for purifying magnetically treated water magnetically treated by the magnetic treatment unit 20,
The magnetic processing unit 20 includes:
A pipe member 22 that is arranged in the water treatment chamber 13 of the casing 12 in the vertical direction and takes in the treated water from the lower part of the casing 12 and pumps it to the upper part of the casing 12;
A magnetic member that is disposed so as to surround a substantially intermediate outer peripheral surface of the pipe member 22 and performs magnetic treatment of the water to be treated when the water to be treated is pumped upward through the pipe member 22. 24, and
The magnetic member 24 is made of a ferrite magnet and is disposed in such a manner that the south pole comes into contact with the outer peripheral surface of the pipe member 22;
The water purification unit is composed of a porous material 32 that adsorbs impurities, and a filter member 34 that filters impurities by passing through the interior of the porous material 32,
The porous material 32 is filled in the water treatment chamber 13 in the casing 12;
The filter member 34 includes a first nonwoven fabric layer 42 wound around the outer periphery of a cylindrical member 36 having a through hole 40, and a fibrous activated carbon nonwoven fabric layer 44 wound around the outer periphery of the first nonwoven fabric layer 42. A laminate 48 in which three layers of a second nonwoven fabric layer 46 wound around the outer periphery of the fibrous activated carbon nonwoven fabric layer 44 are integrally laminated in advance, and a yarn wound around the outer periphery of the laminate 48 Layer 50, and the filtering portion 38 of the filter member 34 is formed below the magnetic member 24.
When the water to be treated is pumped upward from below the pipe member 22, the water to be treated that has been magnetized by the magnetic member 24 and further magnetized is supplied to the top of the pipe member 22, and the pipe The porous material 32 is discharged when the water to be treated which is sent out of the pipe member 22 from the outlet hole 28 of the member 22 and then sent out of the pipe member 22 moves downward by its own weight. The impurities contained in the water to be treated are adsorbed by passing through the inside, and further, the water to be treated in which the impurities are adsorbed by the porous material 32 is further filtered by the thread body layer 50 and the laminate 48. Thus, the water to be treated in which ultrafine substances have been filtered is supplied into the inner cylinder member 36 through the through hole 40 of the cylindrical member 36, and then the water to be treated is Tube Is delivered from the lower end portion 36a of the timber 36 to the water storage chamber 14 inside the casing 12, characterized in that it is discharged to the outside of the casing 12 through the discharge pipe 60 from the reservoir chamber 14.

According to the water treatment apparatus of the present invention, the water to be treated is magnetically treated by the magnetic member, and the water to be treated is purified by the water purifying unit composed of the porous material and the filter member.
Such magnetically treated water reduces water adhesion, so it becomes difficult for water to flow through water pipes (well water pipes), and various facilities such as cooling towers and heat exchangers. Does not degrade the function. In addition, since this magnetically treated water also has the effect of removing water deposits that have already adhered, it should be installed in the middle of water pipes (well water pipes) and at the water intakes of various facilities such as cooling towers and heat exchangers. Thus, the service life of piping and various facilities can be improved.

Furthermore, since the water to be treated is purified by the porous material and the filter member, impurities mixed in tap water and well water can be removed.
The magnetic member used in the water treatment apparatus of the present invention is configured so that the side in contact with the pipe member is an S pole, and is further formed of a ferrite magnet, so that the magnetic treatment is effectively performed on the water to be treated. Therefore, the above effect is particularly excellent.

The filter member used in the water treatment apparatus of the present invention is composed of a predetermined laminate wound around the outer periphery of a cylindrical member and a thread body layer wound around the outer periphery of the laminate.
Therefore, the suspended matter dispersed in the liquid is first filtered step by step in the descending order in the thread layer, and only the very fine suspended matter that has passed through the thread layer reaches the second nonwoven fabric layer. And since it is almost filtered by this 2nd nonwoven fabric layer, the impurity in to-be-processed water can be removed completely.

The porous material used in the water treatment apparatus of the present invention is activated carbon or coral powder.
In this way, it is configured to pass through a porous material that is activated carbon or coral powder before the water to be treated is filtered by the filter member, so it adsorbs extremely fine impurities that cannot be removed by the filter member. The impurities in the water to be treated can be effectively removed.

  As described above, the water treatment apparatus of the present invention is an extremely excellent invention having a number of functions and effects.

Hereinafter, embodiments (examples) of the present invention will be described in more detail with reference to the drawings.
1 is a longitudinal sectional view of an embodiment of the water treatment apparatus of the present invention, FIG. 2 is a sectional view taken along line AA in FIG. 1, and FIG. 3 is a sectional view taken along line BB in FIG. 4 is a cross-sectional view taken along the line CC of FIG. In FIG. 1, 10 shows the water treatment apparatus of the present invention as a whole.

As shown in FIG. 1, the water treatment device 10 has a substantially cylindrical container (casing) 12 having an upper portion formed in a dome shape on a pedestal 11. The container 12 is formed of a metal member such as SUS. The interior of the container 12 is divided into two upper and lower chambers by a partition 15, and the interior is divided into a water treatment chamber 13 and a water storage chamber 14 formed below the water treatment chamber 13. The water treatment device 10 is provided with an air vent valve 16 at its upper end, and is configured to be able to adjust the internal pressure inside the water treatment chamber 13.

  The water treatment chamber 13 includes a magnetic treatment unit 20 that supplies water to be treated and magnetically treats the water to be treated, and a water purification unit 30 that purifies the magnetically treated water. First, the magnetic processing unit 20 will be described.

  The magnetic treatment unit 20 is disposed so as to surround the outer peripheral surface of the pipe member 22 for supplying the water to be treated into the water treatment chamber 13, and when the water to be treated is pumped inside the pipe member. And a magnetic member 24 for magnetically treating the water to be treated.

The pipe member 22 is formed of a metal member such as SUS, and is erected in the vertical direction in the substantially cylindrical water treatment chamber 13. Below this pipe member 22, a supply pipe 27 is connected through the container 12 of the water treatment device 10, while the upper end 4 is connected to the upper end as shown in FIG. Two outlet holes 28 are provided. In the present invention, an example in which four water outlet holes 28 are formed in the pipe member 22 is shown, but there is no particular limitation.

  Since the pipe member 22 is configured in this way, as shown by the arrow in FIG. 1, the water to be treated which is pumped through the supply pipe 27 by a pump (not shown) or the like moves upward in the pipe member 22, It is supplied into the water treatment chamber 13 from the water outlet 28.

Further, a magnetic member 24 is disposed on the outer peripheral surface of the pipe member 22.
As shown in FIGS. 3 and 5, the magnetic member 24 is composed of two members 24 ′ and 24 ″, and these are fixed to the outer peripheral surface of the pipe member 22 by the fixing members 25 and 25. The magnetic member 24 can be formed by appropriately increasing or decreasing the number of members according to the diameter of the pipe.

  As shown in FIGS. 3 and 5, the magnetic member 24 has a protruding portion 24 a that abuts on the outer peripheral surface of the pipe member 22, and the protruding portion 24 a is made of a magnetic material. As the magnetic material, a ferrite magnet having a residual magnetic flux density of 2000 to 4500 G, preferably 3000 to 4200 G, is preferably used, and the side (surface) in contact with the pipe member 22 is arranged as an S pole. The S pole (projecting portion 24a) of the magnetic member 24 is arranged at such a position, and particularly at a position where the S poles (projecting portions 24a) face each other through the pipe member 22 as shown in FIG. By arranging, magnetic processing can be performed efficiently. Therefore, the water magnetically treated in the water treatment apparatus of the present invention can reduce the adhesion of water stains in the pipe, and can further remove the water stains already attached.

  Three magnetic members 24 are arranged in the vertical direction so as to surround the outer peripheral surface of the pipe member 22, and these magnetic members 24 are made of a metal member such as SUS so as not to come into contact with water to be treated. 26. As such a magnetic member 24, a magnetizer (trade name, manufactured by MGI Corporation, residual magnetic flux density 3900G) is specifically used.

The magnetic member 24 magnetically processes the water to be treated when moving upward in the pipe member 22 by a predetermined distance, and the magnetically treated water is supplied into the water treatment chamber 13 from the water outlet hole 28.
As shown in FIG. 1, the water purification unit 30 is a porous material 32 filled in a space formed by a pipe member 22, a cover 26 covering the magnetic member 24, and a filter member 34 in the water treatment chamber 13. And a substantially cylindrical filter member 34 that is disposed in the water treatment chamber 13 and filters the magnetically treated water treated by the porous material 32 inward.

The porous material 32 is not particularly limited, and is activated carbon, silica gel, molecular sieve,
Activated alumina, coral powder, bone charcoal and the like are used. In the present invention, activated carbon and coral powder are preferably used from the standpoints of adsorption capacity, availability, safety and cost. The filling amount of the porous material 32 is not particularly limited, and it is preferable that the amount of the porous material 32 be adjusted so as not to be mixed into the pipe member 22 from the water outlet hole 28 in consideration of the adsorption capacity.

  In the porous material 32, the magnetically treated water supplied into the water treatment chamber 13 from the water outlet hole 28 of the pipe member 22 as described above permeates as shown by the arrow in FIG. Ultrafine impurities mixed in the treated water are adsorbed and then filtered by the filter member 34. Thus, before filtering the water to be treated by the filter member 34, it is possible to adsorb and remove extremely fine impurities that cannot be removed by filtration with the porous material 32, so that the impurities can be effectively removed from the water to be treated. Can be removed.

  On the other hand, the substantially cylindrical filter member 34 has a filtration portion 38 on the outer peripheral surface of the cylindrical member 36, and the cylindrical member 36 is disposed through the partition plate 15 between the water treatment chamber 13 and the water storage chamber 14. The water treatment chamber 13 and the water storage chamber 14 are communicated with each other. That is, as shown in FIGS. 1 and 6, the cylindrical member 36 has an infinite number of through holes 40, so that the treated water filtered by passing through the filtration part 38 inward is further treated with the cylindrical member 36. The hollow portion 42 can be passed through and supplied into the water storage chamber 14. In the present invention, an example in which four filter members 34 are installed will be described, but the present invention is not limited to this.

  As shown in FIGS. 1, 4 and 6, the filter member 34 has a filtering part 38 on the outer peripheral surface of the cylindrical member 36, and the filtering part 38 includes a first nonwoven fabric layer 42 and fibrous activated carbon. A laminate 48 in which three layers of the nonwoven fabric layer 44 and the second nonwoven fabric layer 46 are laminated in advance is wound about 1 to 3 times (see FIGS. 6 and 7). A thread body layer 50 is wound around the outer periphery of the laminate 48.

  Thereby, the water to be treated is filtered through the thread body layer 50, the second nonwoven fabric layer 46, the fibrous activated carbon nonwoven fabric layer 44, and the first nonwoven fabric layer 42. Then, the filtered fluid (water to be treated) flows from the through hole 54 of the filter portion inner cylinder 52 into the hollow portion 42 of the cylindrical member 36 through the through hole 40 of the cylindrical member 36. Yes.

  In this case, the first nonwoven fabric layer 42 covered with the paper material having a density based on JIS-P-8117 in the range of 0.01 to 0.10 seconds covers the entire circumference. It is formed as follows. The first nonwoven fabric layer 42 protects the fibrous activated carbon nonwoven fabric layer 44 mounted on the outer peripheral side of this layer from filtration pressure, and when the filaments are slightly frayed from the fibrous activated carbon nonwoven fabric layer 44, the activated carbon fibers It is a layer for capturing.

The thickness of the first nonwoven fabric layer 42 is in the range of 0.1 to 20 mm, preferably 0.5 to 20 mm, more preferably 0.5 to 15 mm, and further within the range of 1 to 10 mm. It is particularly preferred. The fibrous activated carbon nonwoven fabric layer 44 is a shaped body of fibrous activated carbon that is made into a nonwoven fabric using porous activated carbon fibers as a main raw material. Although this fibrous activated carbon nonwoven fabric has high adsorption efficiency, it has low resistance when liquid passes through it, and unlike ordinary activated carbon, the amount of eluted dust and fibers is extremely small. In addition, since it contains almost no binder, particularly a water-soluble binder, it has a characteristic that it itself does not contaminate water quality despite being shaped into a predetermined shape.

Activated carbon fiber nonwoven fabric forming the fibrous activated carbon nonwoven layer 44 may be in the range a specific surface area of 500~2500m ² / g, preferably in the range of 700~2000m ² / g, more preferably 900~1600m ² / g is a fibrous activated carbon nonwoven fabric having a basis weight within a range of 20 to 350 g / m ² , preferably within a range of 40 to 220 g / m ² , and more preferably within a range of 80 to 150 g / m ^2. . By using fibrous activated carbon having a specific surface area as described above, fine particles in the liquid can be adsorbed. Moreover, filtration efficiency does not fall by using the fibrous activated carbon nonwoven fabric which has the fabric weight in the above ranges.

Such a fibrous activated carbon non-woven fabric itself is usually 0.05 to 3.0 mm, preferably 0.15 to
It has a thickness of 2.5 mm, more preferably 0.30 to 1.8 mm. In the present invention, the fibrous activated carbon nonwoven fabric layer 44 is formed by mounting such a fibrous activated carbon nonwoven fabric in a thickness of 0.1 to 5 mm, preferably 0.3 to 3.3 mm. Furthermore, the second nonwoven fabric layer 46 is preferably formed of a paper material having the same characteristics as the paper material forming the first nonwoven fabric layer 42. That is, the second nonwoven fabric layer 46 is formed of a paper material having a density based on JIS-P-8117 in the range of 0.01 to 0.10 seconds.

The second nonwoven fabric layer 46 functions to filter fine suspended matters that have not been filtered by the thread body layer 50 and to prevent the fibrous activated carbon nonwoven fabric 44 from being unwound by tightening the fibrous activated carbon nonwoven fabric layer 44. Have Therefore, the second nonwoven fabric layer 46 is preferably thicker than the first nonwoven fabric layer 21, and the thickness of the second nonwoven fabric layer 25 is in the range of 0.5 to 15 mm. And it is preferable that the thickness of this 2nd nonwoven fabric layer shall be 1.0-10 mm, and it is especially preferable to set it as 1.5-8 mm.

And when the thickness of the 2nd nonwoven fabric layer 46 is set to 100, the ratio of the thickness of the fibrous activated carbon nonwoven fabric layer 44 is set in the range of 1-40, Preferably it is 5-30, and 1st By setting the thickness ratio of the nonwoven fabric layer 42 in the range of 5 to 90, preferably 10 to 60, high filtration efficiency can be maintained for a long time. The thread body layer 50 is formed by winding the thread body around the outer periphery of the second nonwoven fabric layer 46 with a predetermined thickness. The thread body forming the thread body layer 50 is a thread body having a diameter of 0.5 to 3 mm, preferably 1 to 3 mm. When the thickness of the most preferable yarn body used in the present invention is represented by the yarn count, it is 1 / 0.0 to 1 / 1.0.

  The thread body layer 50 is formed by winding the thread body having the above thickness on the outer peripheral side of the second nonwoven fabric layer 46 to a thickness of 10 to 65 mm, preferably 10 to 50 mm, and particularly preferably 10 to 30 mm. It is formed by doing. That is, by winding to a thickness of at least 10 mm, the filtering ability of the thread body layer 50 is less affected by the type and material of the thread body used. That is, the filtration capacity in the thread body layer 50 varies depending on the winding thickness of the thread body, and hardly varies even if the thread body type, material, and the like are changed. Therefore, the thread body forming the thread body layer 50 does not need to have a special form and does not need to be formed of a special material, and usually used vinyl chloride, polypropylene, polyethylene. Further, synthetic fibers of other synthetic resins or natural fibers such as cotton can be used as they are.

  Note that even if the thread body layer 50 has a thickness exceeding 65 mm (in many cases, 50 mm) and the thread body is wound, the amount of suspended matter filtered by the thread body layer 50 hardly increases. The upper limit of the thickness of the layer 50 is 65 mm, and 30 mm is sufficient for normal use. Such a thread body is preferably wound around the outer periphery of the first nonwoven fabric layer 42 at a predetermined thread interval. That is, it is preferably wound so that the interval between the thread bodies that are wound in the same direction (distance from the center of the thread body to the center of the adjacent thread body) is 2 to 8 mm, It is particularly preferable to wind it so that it is 3 to 7 mm. By winding the thread body at such an interval, the suspended matter having a size of 5 to 150 μm is gradually reduced in the depth direction from the surface of the thread body layer 50. Can be filtered while being distributed.

Moreover, it is not necessary to wind all the thread bodies in the same direction, and it is preferable to wind in different directions for each layer. By winding in such a direction, the suspended matter can be filtered in a stepwise manner, so that the thread layer 50 is less likely to be clogged, and the filtration filter can be used for a long time. . Known means can be adopted as the means for such winding.

  In the filter member 34 configured as described above, for example, dirty water moves from the outer peripheral side to the inner peripheral side of the filter member 34, and the thread body layer 50, the second nonwoven fabric layer 46, and the fibrous activated carbon nonwoven fabric layer 44. And when passing the 1st nonwoven fabric layer 42, it filters efficiently.

  What is necessary is just to use the water treatment apparatus 10 of this invention comprised in this way as follows. First, the water treatment device 10 is disposed in the middle of each pipe through which water passes, for example, a water pipe or a well pipe, and connected to a connection portion (not shown) outside the supply pipe 27 as necessary. Connect the connected pipes. Then, the water to be treated is caused to flow into the pipe member 22 by operating the pump. The treated water that has flowed in is magnetically processed by the magnetic member 24, flows into the water treatment chamber 13 from the water outlet hole 28 of the pipe member 22, and permeates the porous member 32. At this time, the ultrafine suspended matter dispersed in the magnetically treated water is adsorbed on the porous member 32. The magnetically treated water that has passed through the porous member 32 is then filtered by the filter member 34. Specifically, first, the yarn layer 50 is sequentially filtered step by step in descending order. Then, only very fine suspended matters that have passed through the thread body layer 50 reach the second nonwoven fabric layer 46 and are almost filtered by the second nonwoven fabric layer 46. On the other hand, the ultrafine substance in the liquid passes through the thread layer 50 and the second nonwoven fabric layer 46, but is filtered by the fibrous activated carbon nonwoven fabric layer 44 and filtered by the first nonwoven fabric layer 42.

  Therefore, in the water treatment chamber 13, the water to be treated can be magnetically treated and the suspended matter dispersed in the water to be treated can be filtered. And the to-be-processed water which passed the 1st nonwoven fabric layer 42 flows in into the hollow part 42 of the cylindrical member 36 through the through-hole 54 of the filter part inner cylinder 52, and the through-hole 40 of the cylindrical member 36, and lower end part 36a. Into the water storage chamber 14.

The treated water subjected to the magnetic treatment and the filtration treatment in this manner is discharged through a discharge pipe 60 disposed outward from the water storage chamber 14.
Such a water treatment apparatus of the present invention can be variously modified without departing from the object of the present invention.
