Description

  The present invention relates to a liquid reformer and a liquid reformer, and in particular, liquid reforming suitable for reforming water containing radioactive substances, general bacteria, water containing potassium permanganate, and liquid containing polychlorinated biphenyl. And a liquid reformer.

  In recent years, pollution of water on the earth has been increasing. On the other hand, as urbanization progresses, it has become difficult to secure sufficient quality water for drinking or washing in the suburbs of the city. In cities, tap water obtained by purifying and sterilizing water collected in facilities such as dams through many processes is used as water for drinking or washing. Various water purifiers for improving the quality of tap water, and in general, liquid reformers have been developed. Many liquid reforming apparatuses have a complicated structure, and the manufacture of the apparatus requires a troublesome manufacturing process. Further, there has been a problem that the liquid reformer filter must be frequently replaced, or the inside of the liquid reformer must be periodically cleaned at relatively short intervals. In order to improve such problems, a water reforming apparatus having a simple structure is provided for general bacteria (see, for example, Patent Document 1).

  Due to a disaster at a nuclear power plant that occurred on March 11, 2011, radioactive substances are released into the natural world, and these radioactive substances are mixed into tap water, natural drinking water, and pool water. A liquid reformer for removing radioactive substances from water and obtaining water suitable for drinking water and water suitable for use in pools is extremely expensive, and it is economically expensive to adopt in general households and pool facilities. It is too much.

  In addition, in the pool, it is required to circulate by filtering water containing potassium permanganate, E. coli, and general bacteria other than radioactive substances through a filter. Such a filter is also large. It was expensive. Also, polychlorinated biphenyl (PCB) has been widely used as insulation oil for cables (electric wires) and insulation oil for transformers. When the concentration of PCB of these cables and transformers exceeds a predetermined value, it is regulated by law to dispose as general industrial waste. However, the operation of separating polychlorinated biphenyl from the liquid contained in the cable and transformer is extremely difficult, and it is not easy to dispose of the cable, transformer and insulating oil used in these.

About liquid reformer
The liquid reformer of the embodiment will be described with reference to FIGS. 1 and 2. FIG. 1 is a diagram illustrating a liquid reformer 1 that is a main part of a liquid reforming apparatus according to an embodiment. FIG. 1A is a plan view of the liquid reformer 1 as viewed from above. FIG. 1B is a front view of the liquid reformer 1 as seen from the front. FIG. 1C is a right side view of the liquid reformer 1 viewed from the right side.

  The structure of each part of the liquid reformer 1 will be described with reference to FIGS. 1 (A) to 1 (C). The liquid reformer 1 includes a liquid reforming container 10, a first plate member 15, a second plate member 16, a water supply pipe 11, and a drain pipe 12. The liquid reforming container 10 is made of, for example, a plastic material. The material of the liquid reforming container 10 may be a material that does not corrode by liquid and may be ceramic.

  The liquid reforming container 10 has a structure in which the liquid stored in the container does not leak. The liquid reforming container 10 is formed by a liquid reforming container cover 10a, a liquid reforming container bottom 10b, and a liquid reforming container side 10c. The liquid reforming container bottom 10b and the liquid reforming container side 10c are integrally formed, the liquid reforming container side 10c is a tapered cylinder, and the liquid reforming container bottom 10b has a disk shape. The liquid reforming container cover 10a is formed of a separate member, and the shape of the liquid reforming container cover 10a is a disk shape. The liquid reforming container covering portion 10a functions as a plate material attachment member to which one end of the plate material 15 and one end of the plate material 16 are fixed.

  An upper surface portion of the liquid reforming container 10 is covered with a liquid reforming container covering portion 10a that can be attached and detached. In short, the liquid reforming container 10 can store liquid inside, and can hold a water supply pipe 11 to be described later, a drain pipe 12 to be described later, a first plate member 15 to be described later, and a second plate member 16 to be described later. I just need it.

  For example, in the embodiment, the size of the liquid reforming container 10 is set as follows. The distance between the liquid reforming container cover 10a and the liquid reforming container bottom 10b is 35 cm (centimeter), the diameter of the liquid reforming container cover 10a is 25 cm, and the diameter of the liquid reforming container bottom 10b is 15 cm. Has been.

  The arrangement relationship among the water supply pipe 11, the drain pipe 12, and the liquid reforming container 10 will be described. The water supply pipe 11 penetrates the liquid reforming container side portion 10c of the liquid reforming container 10, and this penetrating part is waterproofed so that liquid does not leak from the penetrating part. Similarly, the drain pipe 12 penetrates the liquid reforming container side portion 10c of the liquid reforming container 10, and this penetrating part is waterproofed so that no liquid leaks from the penetrating part.

  The water supply pipe 11 guides the liquid to the inside of the liquid reforming container 10, and the drain pipe 12 guides the liquid to the outside of the liquid reforming container 10. The water supply pipe 11 and the drain pipe 12 are made of materials that are not eroded by the liquid, and are made of, for example, vinyl chloride or stainless steel. The water supply pipe 11 and the drain pipe 12 are cylindrical tubes having a diameter of 22 mm (millimeters).

  As described above, the liquid flows in from the first opening 11a (hereinafter abbreviated as opening 11a) of the water supply pipe 11, and the second opening 11b of the water supply pipe 11 (hereinafter abbreviated as opening 11b). ), A liquid is ejected from a third opening 11c (hereinafter abbreviated as opening 11c) of the water supply pipe 11. The other end of the water supply pipe 11 is a closed portion 11d so that liquid does not flow out.

  As described above, the liquid flows in from the first opening 12a (hereinafter abbreviated as the opening 12a) of the drain pipe 12 of the liquid reforming vessel 10, and the second opening 12b (hereinafter, referred to as the opening 12a) of the drain pipe 12. The liquid flows out from the opening 12b. An arrow in FIG. 1B indicates the moving direction of the liquid. Here, regarding the relationship between the opening 12 a of the drain pipe 12 and the liquid level position of the liquid stored in the liquid reforming container 10, the liquid level position is above the opening 12 a of the liquid reforming container 10. Thus, the liquid can flow in from the opening 12a of the drain pipe 12 and flow out of the opening 12b.

  The first plate material 15 (hereinafter abbreviated as plate material 15) and the second plate material 16 (hereinafter abbreviated as plate material 16) are made of stainless steel or titanium, which is a material that is not corroded by the liquid in the liquid reforming vessel 10. It is formed. The length of the plate material 15 in the longitudinal direction (vertical direction of the paper surface) and the length of the plate material 16 in the longitudinal direction are substantially the same length. The short direction of the plate material 15 and the short direction of the plate material 16 are part of the arc. The longitudinal direction of the plate member 15 and the longitudinal direction of the plate member 16 are arranged in substantially the same direction as the direction of the portion extending in the vertical direction of the water supply pipe 11. One end surface of the plate member 15 is bent in an L shape, and the bent portion is fixed to the liquid reforming vessel cover 10a with screws. Similarly, one end surface of the plate member 16 is bent in an L shape, and the bent portion is fixed to the liquid reforming vessel cover 10a with a screw. In this manner, the liquid reforming container covering portion 10a functions as a plate material attachment member to which one end of the plate material 15 and one end of the plate material 16 are fixed.

  FIG. 2 is a perspective view schematically showing a three-way arrangement relationship of the water supply pipe 11, the plate material 15, and the plate material 16 in the liquid reformer 1. The plate material 15 and the plate material 16 are arranged so as to surround the water supply pipe 11. The distance between the plate material 15 and the plate material 16 is wide at the upper part and narrower at the lower part, and is arranged in a taper shape. The distance L1 at the upper part of the plate material 15 and the plate material 16 is 15 cm, and the distance L2 at the lower part of the plate material 15 and the plate material 16 is 10 cm. The length L3 of the plate material 15 and the length L6 of the plate material 16 are each 30 cm. The width L4 of the plate material 15 is 1 cm, and the width L5 of the plate material 16 is 2 cm.

  The opening 11b of the water supply pipe 11 is disposed to face the plate member 16, and the opening 11c of the water supply pipe 11 is disposed to face the plate member 15 (not shown in FIG. 2, refer to FIG. 1). The liquid ejected from the opening 11 b of the water supply pipe 11 collides with the plate material 16, and the liquid ejected from the opening 11 c of the water supply pipe 11 collides with the plate material 15. Here, the plate material 15 and the plate material 16 are arranged in a taper shape because the distance between the opening portion 11c and the plate material 15 and the distance between the opening portion 11b and the plate material 16 are narrowed to make the opening portion 11c and the opening portion 11b. This is because a high water pressure of the liquid flowing out from the plate is applied to the plate member 15 and the plate member 16. When the water pressure is high, the plate material 15 and the plate material 16 are not necessarily arranged in a taper shape.

  The high water pressure liquid ejected from the opening 11c collides with the plate material 15 to vibrate the plate material 15, and the high water pressure liquid ejected from the opening 11b collides with the plate material 16 to vibrate the plate material 16. Here, the high water pressure refers to a water pressure sufficient to vibrate the plate material 15 and the plate material 16. Since the width L5 of the plate material 16 and the width L4 of the plate material 15 are different, the natural resonance frequency of the vibration of the plate material 15 and the natural resonance frequency of the vibration of the plate material 16 are different. For example, the natural resonance frequency of the plate material 15 having a width of 1 cm is higher than the natural resonance frequency of the plate material 16 having a width of 2 cm.

  In addition to making the width L5 of the plate material 16 different from the width L4 of the plate material 15, in order to make the natural resonance frequency of the vibration of the plate material 15 different from the natural resonance frequency of the vibration of the plate material 16, the following may be performed. . The length L3 of the plate material 16 and the length L6 of the plate material 15 may be different. The thickness of the plate material 16 may be different from the thickness of the plate material 15.

  Although the liquid reformer 1 produces a good reforming effect as shown in Experimental Examples 1 to 4 to be described later, the inventor has not established a clear theory on the operation principle. . However, the inventor makes the vibration frequency of the plate material 15 and the vibration frequency of the plate material 16 different from each other based on many years of experiments and experience, and the ratio of the natural resonance frequency of the plate material 15 to the natural resonance frequency of the plate material 16 is 1. It has been found that a good reforming effect is produced in the range of 5 to 3. It has also been found that the best modification effect is produced when the ratio of the natural resonance frequency of the plate material 15 and the natural resonance frequency of the plate material 16 is approximately 2.

  Although the size and shape of each part of the liquid reformer 1 of the embodiment are not limited to this, the same effects are produced. For example, the plate material 15 and the plate material 16 may be flat, and the water supply pipe 11 and the drain pipe 12 may be square. Since the liquid reformer 1 having such a size and shape is suitable for obtaining experimental data, the inventor will show experimental examples 1 to 4 described later by the liquid reformer 1. Experimental data was collected.

Has been made.

  The pipe joint 21 connects the water supply pipe 11 and the extended water supply pipe 23. The pipe joint 22 connects the drain pipe 12 and the extended drain pipe 24. The pump 25 has a liquid suction port 25a and a discharge port 25b. The discharge port 25 b is connected to the opening 23 a of the extended water supply pipe 23. The opening 24 a of the extended drain pipe 24 and the suction port 25 a of the pump 25 are disposed inside the liquid below the liquid level of the liquid in the liquid storage container 30. By operating the pump 25, the liquid inside the liquid storage container 30 passes through the water supply pipe 11 of the liquid reformer 1 as shown by the arrow in the figure, and the inside of the liquid reforming container 10 of the liquid reformer 1. Through the drain pipe 12 and circulate back to the liquid storage container 30 again.

  The liquid storage container 30 may be a pool for a person to swim, or a bucket for storing a predetermined amount of liquid. The liquid reforming apparatus 2 circulates the liquid between the liquid reforming container 10 and the liquid storage container 30, thereby reforming the liquid having the capacity of the liquid storage container 30 exceeding the capacity of the liquid reforming container 10. can do.

  FIG. 4 is a diagram illustrating a liquid reformer according to another embodiment. With reference to FIG. 4, the liquid reformer 3 of the embodiment using the liquid reformer 1 of the embodiment will be described. The difference between the liquid reformer 3 shown in FIG. 4 and the liquid reformer 2 shown in FIG. 3 is that the liquid reformer 3 does not include the liquid storage container 30. The liquid reformer 3 can reform the amount of liquid equal to the capacity of the liquid reforming container 10 by circulating the liquid inside the liquid reforming container 10.
