Description

The present invention relates to a fluid heating device that is arranged in a pipe without using a heater and self-heats the fluid itself that circulates in the pipe.

Conventionally, as a device for heating water in a bathtub with an electric heat source, a pipe line A connecting the bathtub and the filter, a circulation pump connected to the pipe line, and a filter and the bathtub are used.

However, in this conventional heating device, a heater is attached to the outer peripheral surface of the pipe line B to heat the pipe line B, thereby heating the hot water flowing in the pipe line B to a predetermined temperature, so that the hot water temperature rises. It has a problem that the speed is slow and the heating efficiency is very poor. Therefore, in order to make up for the shortage of the hot water temperature rising speed of the heater, it is conceivable to install a water heater in the same place, but there are problems such as complicated configuration of the heating system and high cost.

However, in the bath device of Patent Document 1, an electromagnetic wave generator is arranged in a piping path for circulating hot water in the bathtub, the piping path is heated by electromagnetic waves, and the hot water flowing in the piping path is directly heated. However, even if the piping portion in which the electromagnetic coil is arranged is heated, the heat is cooled by the time it reaches the bathtub, which causes a problem of inefficiency. Further, the fluid heating device of Patent Document 2 is originally for air conditioning of buildings and buildings, requires large-scale equipment, is not suitable for applications such as heating hot water in a bathtub, and is small in size. There is a problem that it is difficult to realize with a device and it is costly.

In view of the above problems, in view of the above problems, the fluid itself flowing through the piping path self-heats, and by heating the piping pipe, the water in the bathtub through which the piping pipe passes is changed to hot water in a short time, and the fluid is easy to maintain and manage. The purpose is to provide a heating device.

In order to solve the above problem, the fluid heating device according to the present invention is a fluid heating device that is installed inside a piping pipe and self-heats when the fluid passes through and collides with the fluid, and is inside a cylinder. A plurality of protrusions are projected from the inner peripheral surface of the cylinder toward the center so as to form a fluid flow path, and the protrusions are mushroom-shaped composed of a mandrel and a head, and the protrusions are formed. It is characterized by comprising a turbulent flow generation ring in which at least two kinds of dimensions are combined.

Further, in the fluid heating device according to the present invention, the above-mentioned turbulent flow generation ring and the fluid flow path are formed inside the cylinder so that the inner peripheral surface of the cylinder is from the inlet of the fluid flow path. It is composed of a flow velocity amplification ring that is tapered toward the outlet, and the flow velocity amplification ring is arranged upstream of the turbulence generation ring.

Further, the fluid heating device according to the present invention has the above-mentioned turbulence generation ring, the above-mentioned flow velocity amplification ring, and a plurality of blades in the cylinder so as to form a fluid flow passage inside the cylinder. A fixed wing is provided, and each wing portion of the fixed wing is positioned in a fluid flow. The fixed wing has a columnar inner core portion provided inside the cylinder, and an inner peripheral surface and an inner core portion of the cylinder. It consists of a flow velocity slowing ring composed of a plurality of blades radially provided between and, the flow velocity amplification ring is arranged upstream of the turbulence generation ring, and the flow velocity slowdown ring is the flow velocity amplification ring and the turbulence. It may be arranged between the generation ring and the generation ring.

In the electromagnetic wave generator according to the present invention, it is preferable that one flow velocity slow ring, one flow velocity amplification ring, and a plurality of turbulence generation rings are combined as a set.

If the fluid is antifreeze, it is suitable for heating the piping.

By using the fluid heating device of the present invention, the water in the bathtub can be changed to hot water in a short time by the heat of the heated pipe by heating the pipe itself while the fluid itself heats itself. In addition, in the case of hot water supply by a normal boiler, it is necessary to manage the boiler because an overheated state is always required. However, the equipment can be operated immediately when necessary, and maintenance management is only replenishment of solution and simple repair and inspection. , There is an effect that the cost can be reduced.

Hereinafter, examples of the present invention will be described in detail with reference to the drawings. In each figure, the same parts are assigned the same number, and duplicate description is omitted. In addition, it should be noted that the drawings may be exaggerated in order to understand the present invention, and are not necessarily expressed precisely according to the scale. The present invention is not limited to the examples shown below.

Before explaining the examples, the gist of the present invention will be described. The present inventor has proposed a water treatment method (International Publication No. WO / 2015/145563) for refining clusters of water molecules. In this water treatment method, a cavitation generating ring in which a plurality of protrusions are projected from the inner peripheral surface of the cylindrical portion toward the center so as to form a water flow passage inside the cylindrical portion is formed on the flowing water pipe. It is a water treatment method that is installed in a part of the cylinder and allows water to pass through the cylinder at high pressure to cause cavitation in the cylinder and to make clusters of water molecules finer. In this water treatment method and water treatment device, a magnetic field is applied to the conductive vacuum microbubbles generated by cavitation to generate a force based on Fleming's left-hand rule, and the force is used around the vacuum microbubbles. It is a miniaturization of clusters of water molecules. When a fluid collides with a protrusion in a piping pipe, the pressure of the fluid around the collided part momentarily drops, causing the fluid to boil or release dissolved gas, which causes the fluid to boil. It is based on the fact that many small bubbles (vacuum microbubbles) are known to be generated.
As an application of the water treatment method, when a ring similar to a cavitation generation ring was placed in a piping pipe and an experiment in which a fluid such as water was circulated by a pressure pump was repeated, it was discovered that the piping pipe became hot.
The present inventor has come up with the structure of the present invention in which the fluid can be self-heated when a ceramic body is used as the material of the ring while repeating the invention, trial production, and experiment of various rings. That is, it is considered that the energy motion of the fluid itself has led to self-heating regardless of the properties of the gas or liquid. That is, in the process of cavitation of the fluid, under certain conditions, the fluid flowing at high pressure collides with the protrusions of the ceramic body or causes friction, and far infrared rays are generated to draw out the self-heating of the fluid. As a result, it is thought that the piping pipe through which the fluid flows is heated.

The first embodiment will be described in detail with reference to the drawings. 1A and 1B are views showing the structure of the turbulent flow generation ring 1 according to the present invention, where FIG. 1A is a schematic front view and FIG. 1B is a schematic vertical sectional view taken along line XX of FIG.

See FIGS. 1 (a) and 1 (b). The turbulent flow generation ring 1 according to the present invention has a plurality of protrusions 11a, 11b, 11c, from the inner peripheral surface 10 of the cylinder toward the center so as to form a flow passage 13 of the fluid L inside the cylinder. 12a, 12b, and 12c are projected. In the first embodiment, the turbulent flow generation ring 1 has a plurality of protrusions 11 (11a, 11b, 11c in the figure) and a plurality of protrusions 12 (12a, 12b, 12b in the figure) having substantially the same size and shape. 12c), the protrusions 11 and 12 have a mushroom shape composed of mandrel 110, 120 and heads 111, 121, and the dimensions of the heads 111, 121 are at least two or more combinations.
As will be described later, the protruding dimension of the protruding portion 11 is larger than that of the protruding portion 12, but the protrusion size is not particularly limited.

See FIG. FIG. 2A is a schematic perspective view showing a mushroom-shaped member 11 of the turbulent flow generation ring according to the present invention. FIG. 2B is a schematic perspective view showing the mushroom-shaped member 12 of the turbulent flow generation ring according to the present invention.
As shown in FIG. 2A, the protrusion 11 has a mushroom shape including a mandrel 110 and a head 111. As shown in FIG. 2B, the protrusion 12 has a mushroom shape including a mandrel 120 and a head 121. The protrusions 11 and 12 have two or more combinations of the heights of the mandrel 110 and 120 and the dimensions of the heads 111 and 121. In FIGS. 1 and 2, the shapes of the heads 111 and 121 are substantially disk-shaped, and two types of heads 111 and 121 and the protrusions 11 and 12 in which the mandrel 110 is higher than the mandrel 120 are illustrated. There is. By combining two or more types of protrusions 11 and 12 in this way, the above-mentioned shock wave can be efficiently generated. Further, by making the heads 111 and 121 substantially disk-shaped, turbulence can be generated in the fluid L flowing in the piping pipe.
The size of the protrusions 11 and 12 may be set so that the protrusions 11 and 12 do not interfere with each other. Further, the sizes of the heads 111 and 121 are shown by way of example and are not limited, and different shapes and dimensions such as three types and four types can be used as long as the protrusions do not interfere with each other.

See FIG. FIG. 3 is a cross-sectional view showing a state in which the flow velocity amplification ring 2 and the turbulence generation ring 1 are combined. In this combination, the flow velocity amplification ring 2 is arranged on the upstream side, and the turbulence generation ring 1 is arranged adjacent to the downstream side.

See FIG. 4A and 4B are views showing the structure of the flow velocity amplification ring 2, where FIG. 4A is a schematic front view, FIG. 4B is a schematic rear view, and FIG. 4C is a schematic vertical cross-sectional view taken along the line YY. Referring to FIG. 4C, in the flow velocity amplification ring 2, the inner peripheral surface 20 of the cylinder is tapered from the inlet opening 21 toward the outlet opening 22, and this is a flow passage of the fluid L inside the cylinder. 23 is formed. As shown in FIG. 4A, in the first embodiment, a peripheral groove 24 is formed between the inlet opening 21 on the front surface of the flow velocity amplification ring 2 and the outer peripheral end of the cylinder, but it is not always necessary. As shown in FIG. 4B, a plurality of small recesses 250 are bored in the back surface 25 between the outlet opening 22 of the flow velocity amplification ring 2 and the outer peripheral end of the cylinder. As will be described later, in the plurality of small recesses 250, the accelerated fluid L enters the inlet opening of the turbulent flow generation ring 1 from the outlet opening 22 of the flow velocity amplification ring 2 and collides with the protrusions 11 and 12. When the shock wave returns to the outlet opening 22 of the flow velocity amplification ring 2, it has a role of diffusely reflecting the shock wave.

A configuration in which the flow velocity amplification ring 2 and the turbulence generation ring 1 shown in FIG. 3 are combined will be described. When the fluid L is passed through the flow velocity amplification ring 2 and the turbulence generation ring 1 at high pressure by a pressure pump, the fluid L first enters the cylinder of the flow velocity amplification ring 2 from the inlet opening 21 toward the outlet opening 22. In the process of traveling through the tapered flow passage 23, the flow velocity is amplified. The accelerated fluid L enters the inlet opening of the turbulent flow generation ring 1 from the outlet opening 22 of the flow velocity amplification ring 2 and collides with the protrusions 11 and 12. Then, the pressure of the fluid around the collision site is momentarily reduced. When the pressure of the fluid is lowered for a very short time, the fluid L boils or the dissolved gas is liberated around the minute bubble nuclei of 100 μm or less existing in the fluid L, which causes small bubbles (vacuum). It is known that a large number of microbubbles) are generated. Since the pressure of the fluid L around these vacuum microphone bubbles is higher than the saturated water vapor pressure, the fluid L flooded at the moment when the surrounding fluid L flooded toward the center of the vacuum microbubbles and the vacuum microbubbles disappeared. It collides at the center, which causes a strong shock wave.

Then, as described above, in the process of cavitation of the fluid L, the fluid L flowing at high pressure collides with the protrusions 11 and 12 of the ceramic body of the turbulent flow generation ring 1, or causes friction on a part of the protrusions 11 and 12. When it is generated, far infrared rays are generated. It is thought that this far infrared ray draws out the self-heating of the fluid, which in turn heats the piping pipe through which the fluid flows.

The material used for the slow flow velocity ring 1 according to the present invention is a non-oxide ceramic body such as silicon nitride, sialon, silicon carbide, or boron nitride made of porous material, and a single material of zirconia, alumina, and mulite made of porous material. Or, it is composed of a composite material of non-oxide ceramic bodies such as boron nitride and silicon nitride, or a composite material of a non-oxide ceramic body such as boron nitride and an oxide ceramic body such as zirconia, alumina, and mulite. Is suitable. These ceramic bodies are particularly excellent in heat resistance, corrosion resistance, and heat impact resistance at high temperatures.
Further, the flow velocity amplification ring 2 may be made of a metal such as stainless steel, a synthetic resin, or the like, in addition to the above-mentioned material such as a ceramic body.
If the material used is a ceramic body, when the fluid L flowing in the piping pipe collides with the ceramic body protrusion, the far infrared rays radiated from the ceramic body due to the impact heat the temperature of the flowing fluid L. It is considered to work.

Further, the inner diameter of the cylinder of the flow velocity amplification ring 2 and the turbulence generation ring 1 according to the present invention may be, for example, 10 to 50 mm, and the width dimension of the cylinder (dimension along the flow direction of the fluid L) is, for example, 5. It may be ~ 30 mm. The protruding dimensions of the protrusions 11 and 12 of the turbulent flow generation ring 1 may be such that the protrusions 11 and 12 do not interfere with each other. For example, the protrusions are about 1/10 to 1/2 of the inner diameter of the cylinder. May be.

The second embodiment will be described in detail with reference to the drawings.

See FIG. FIG. 5 is a cross-sectional view showing a state in which the flow velocity amplification ring 2, the flow velocity slowing ring 3, and the turbulent flow generation ring 1 are combined. In this combination, the flow velocity amplification ring 2 is arranged on the upstream side, and the flow velocity slowing ring 3 is sandwiched between the turbulent flow generation ring 1 and the flow velocity amplification ring 2 on the downstream side. Hereinafter, the description of the flow velocity amplification ring 2 and the turbulence generation ring 1 according to the second embodiment is the same as that of the first embodiment, and the description overlapping with the first embodiment will be omitted in the second embodiment.

6A and 6B are views showing the structure of the slow flow velocity ring 3, where FIG. 6A is a schematic front view and FIG. 6B is a schematic vertical cross-sectional view taken along the line ZZ of FIG. 6A.
The flow velocity slow ring 3 is provided with a fixed wing 31 having a plurality of wing portions 31a, 31b, 31c in the cylinder so as to form a flow passage 33 of the fluid L inside the cylinder, and each wing of the fixed wing 31. The parts 31a, 31b and 31c are located in the flow of the fluid L. That is, the fixed wing 31 has a plurality of wing portions 31a, 31b, 31c radially provided between the cylindrical inner core portion 35 provided inside the cylinder and the inner peripheral surface 30 and the inner core portion 35 of the cylinder. It is composed of and. The fluid L flows through the flow passage 33 through the gaps between the plurality of blade portions 31a, 31b, 31c and the inner core portion 35 provided radially between the inner peripheral surface 30 of the cylinder and the inner core portion 35.

A configuration in which the flow velocity amplification ring 2, the flow velocity slowing ring 3, and the turbulent flow generation ring 1 shown in FIG. 5 are combined will be described. When the fluid L is passed through the flow velocity amplification ring 2, the flow velocity slowing ring 3, and the turbulence generation ring 1 at high pressure by a pressure pump, the fluid L first enters the cylinder of the flow velocity amplification ring 2 through the inlet opening 21 and exits. The flow velocity is amplified in the process of advancing the tapered flow passage 23 toward the opening 22. The accelerated fluid L enters the inlet opening of the slow flow velocity ring 3 from the outlet opening 22 of the flow velocity amplification ring 2 and collides with the front 350 of the inner core portion 35, where a strong shock wave is generated. That is, the fluid L circulated at high pressure collides with the front surface 350 of the inner core portion 35 of the ceramic body of the slow flow velocity ring 3, and far infrared rays are generated. It is thought that this far infrared ray draws out the self-heating of the fluid, which in turn heats the piping pipe through which the fluid flows.
When the fluid L flowing at high pressure collides with the front surface 350 of the inner core portion 35 of the ceramic body of the slow flow velocity ring 3, the fluid L is diffusely reflected in a plurality of small recesses 350 formed in the front surface 350. Then, when the shock wave returns to the outlet opening 22 of the flow velocity amplification ring 2, the diffusely reflected fluid L further diffusely reflects the shock wave in the plurality of small recesses 250. The diffusely reflected liquid L flows through the flow passage 33 through the gap between the plurality of blade portions 31a, 31b, 31c and the inner core portion 35 while colliding with the plurality of blade portions 31a, 31b, 31c of the fixed blade 31, and the flow velocity slow ring. It flows from the outlet opening of 3 into the inlet opening of the turbulent flow generation ring 1.
After that, the fluid L generates a turbulent flow through the protrusions 11 and 12 arranged in the cylinder of the turbulent flow generation ring 1, and flows out from the outlet opening.
By combining the flow velocity amplification ring 2 of the second embodiment, the slow flow velocity ring 3, and the turbulent flow generation ring 1, the flow of the fluid L can be changed from the flow velocity amplification to the slow flow velocity, and the flow itself can be turbulent. , It seems that it leads to increase the entropy of kinetic energy.

The material used for the slow flow velocity ring 3 according to the present invention is a non-oxide ceramic body such as silicon nitride, sialon, silicon carbide, or boron nitride made of porous material, and a single material of zirconia, alumina, and mulite made of porous material. Or, it is composed of a composite material of non-oxide ceramic bodies such as boron nitride and silicon nitride, or a composite material of a non-oxide ceramic body such as boron nitride and an oxide ceramic body such as zirconia, alumina, and mulite. Is suitable. These ceramic bodies are particularly excellent in heat resistance, corrosion resistance, and heat impact resistance at high temperatures. When the material used is a ceramic body, it is considered that the temperature of the fluid L through which the far infrared rays radiated from the ceramic body when an impact is applied can be heated.

Further, the inner diameter of the cylinder of the flow velocity slow ring 3 according to the present invention may be, for example, 10 to 50 mm, as in the flow velocity amplification ring 2 and the turbulence generation ring 1 of the first embodiment, and the width dimension of the cylinder (fluid L). The dimension along the flow direction of the above) may be, for example, 5 to 30 mm.

The third embodiment will be described in detail with reference to the drawings.

See FIG. 7. FIG. 7 is a cross-sectional view showing an example of a state in which a fluid heating device in which one flow velocity amplification ring, one flow velocity slowing ring, and a plurality of turbulent flow generation rings are combined is arranged in a pipe pipe.

In Example 3, the fluid heating device 100 shows an example as a device in which one flow velocity amplification ring 2, one flow velocity slowing ring 3, and four turbulent flow generation rings 1 are combined. In the third embodiment, four turbulent flow generation rings 1 are arranged, but the number is not particularly limited. As shown in FIG. 7, the fluid heating device 100 of the above combination is installed in a part of the piping pipe P, the fluid L is passed through the cylinder, and the fluid L is the inner core portion 35 of the ceramic body of the slow flow velocity ring 3. Far infrared rays are generated by colliding with the front surface 350, and further, the fluid L generates turbulent flow through protrusions 11 and 12 arranged in the cylinder of the first turbulent flow generation ring 1, and flows out from the outlet opening. Further, turbulence is generated through the protrusions arranged in the cylinder of the second turbulence generation ring 1, and the turbulence is amplified by passing through the plurality of turbulence generation rings 1.

FIG. 8 is a diagram showing a piping system in which the plurality of fluid heating devices 100 shown in FIG. 7 are arranged in a piping pipe. This is an example assuming that the fluid heating device 100 is arranged in a facility having a bathtub. In this way, by arranging the plurality of fluid heating devices 100 shown in FIG. 7, the water in the bathtub can be changed to hot water in a short time by heating the piping pipe itself while the fluid itself heats itself. it can. It is preferable that at least three sets of the fluid heating devices 100 are continuously arranged in a part of the piping pipe. Further, if a plurality of sets of the above-mentioned fluid heating devices are arranged in the flow path of the piping pipe, the heating efficiency is improved.

As the pressurizing pump, any pump may be used as long as the fluid L can be circulated in the piping pipe P at a high pressure, and pumps having various configurations can be used. Further, the piping pipe P may be a pipe P having a structure capable of withstanding the flow of a high-pressure fluid L, for example, one made of a metal such as iron or copper, or one made of a synthetic resin such as polyvinyl chloride. Etc. may be used. Further, the pressure of the fluid L passing through the flow velocity amplification ring 2, the flow velocity slow ring 3, and the turbulence generation ring 1 may be about 1 to 10 MP, and the flow velocity of the fluid L should be 150 m / min or more. Just do it. The pressure and flow velocity of the fluid L may be appropriately adjusted in order to generate a shock wave effective for heating the fluid L, and may be adjusted according to, for example, the temperature of the fluid L. ..
