Description

Technical Field

[0001] The present invention relates to a heat exchange device that exchanges heat between a heat exchange fluid that has become high or low temperature and a heat exchange fluid supplied to a heat exchange fluid pipe.

Background Art

[0002] Conventionally, high or low temperature wastewater generated from factories, various plants, etc. has flowed out to the outside and been discarded as it is. In the case of high temperature wastewater, for example, since fossil fuel is burned to make it high temperature, recovering heat from the wastewater can save energy and also lead to a reduction in carbon dioxide emissions.

[0003] Many heat exchange devices that can recover heat from such wastewater and the like have been proposed conventionally.

[0004] Among these, for example, Patent Document 1 discloses a heat exchange device having a configuration in which, in a heat exchange fluid circulation path, the heat exchange fluid is circulated from an inlet to an outlet using potential energy, and the direction in which the heat exchange fluid flows with respect to the heat exchange fluid to be heat-exchanged is a countercurrent.

Summary of the Invention

Problems to be Solved by the Invention

[0006] But, in such a conventional heat exchange device, there is a problem that since a mold with a complex structure is used and a lot of materials are used for manufacturing, the manufacturing efficiency is low and the material cost also increases.

[0007] Therefore, the present invention has been made in view of these circumstances, and its objective is to provide a heat exchange device that can increase manufacturing efficiency while keeping material costs low. [Means for solving the problem]

[0008] To achieve the above objective, the invention described in claim 1 comprises a heat exchange device body having an inlet through which a heat exchange fluid, discharged from a heat source that becomes high or low temperature using potential energy via a discharge means at a predetermined height, flows in; a heat exchange fluid circulation path through which the heat exchange fluid that has flowed in from the inlet circulates; an outlet through which the heat exchange fluid that has passed through the heat exchange fluid circulation path flows out; and a heat exchange fluid piping inserted from the outlet side, through the heat exchange fluid circulation path, to which a heat exchange fluid to be exchanged is supplied, wherein the circulation path body portion of the heat exchange fluid circulation path through which the heat exchange fluid flows is formed by a cylindrical member in a spiral shape in plan view.

[0009] The invention described in claim 2 is characterized in that, in the invention described in claim 1, the height position of the outlet is set lower than the predetermined height of the discharge means and higher than the height position of the circulation path main body made of the cylindrical member.

[0010] The invention described in claim 3 comprises a heat exchange device body having an inlet through which a heat exchange fluid, discharged from a heat source that becomes high or low temperature using potential energy via a discharge means at a predetermined height, flows in; a heat exchange fluid circulation path through which the heat exchange fluid that has flowed in from the inlet circulates; an outlet through which the heat exchange fluid that has passed through the heat exchange fluid circulation path flows out; and a heat exchange fluid piping inserted from the outlet side, through the heat exchange fluid circulation path, to which a heat exchange fluid to be exchanged with the heat exchange fluid is supplied, characterized in that the circulation path body portion of the heat exchange fluid circulation path through which the heat exchange fluid flows is formed in a spiral shape in plan view, with a groove-shaped member having an open top surface.

[0011] The invention described in claim 4 is characterized in that, in the invention described in claim 1 or 3, the heat-exchanged fluid is supplied in the heat-exchanged fluid piping in the opposite direction to the direction in which the heat-exchanged fluid flows in the heat-exchanged fluid circulation path, and the heat-exchanged fluid is exchanged with the heat-exchanged fluid.

[0012] The invention described in claim 5 is characterized in that, in the invention described in claim 1 or 3, a plurality of heat-exchanged fluid pipes are provided within the heat-exchanged fluid circulation path. [Effects of the Invention]

[0013] According to the invention described in claim 1, for example, the circulation path body of the heat exchange fluid circulation path that constitutes the heat exchange device body can be manufactured by a simple method such as bending a straight cylindrical member into a spiral shape, thereby increasing manufacturing efficiency, and material costs can be kept low because the material between adjacent heat exchange fluid circulation paths can be omitted structurally.

[0014] According to the invention described in claim 2, the height of the outlet is set lower than a predetermined height of the discharge means and higher than the height of the circulation path body made of a cylindrical member. As a result, the heat exchange fluid flowing in from the inlet always fills the heat exchange fluid circulation path, and after sufficient heat exchange has taken place between the heat exchange fluid and the heat-exchanged fluid, it is discharged from the outlet. This allows for highly efficient heat recovery, the overall size of the heat exchange device can be made compact, and a film of dirt is less likely to form on the surface of the heat-exchanged fluid piping, thus requiring almost no internal cleaning.

[0015] According to the invention described in claim 3, for example, the circulation path body of the heat exchange fluid circulation path that constitutes the heat exchange device body can be manufactured by a simple method such as bending a straight cylindrical member into a spiral shape and then dividing it in half in the cross-sectional direction. This increases manufacturing efficiency, and structurally, it is possible to omit material between adjacent heat exchange fluid circulation paths, thus keeping material costs low.

[0016] According to the invention described in claim 4, in the heat exchange fluid pipe, the heat exchange fluid to be heat-exchanged with the heat exchange fluid is supplied in a direction opposite to the direction in which the heat exchange fluid in the heat exchange fluid circulation path flows, and the flow of the heat exchange fluid and the flow of the heat exchange fluid to be heat-exchanged are in a countercurrent flow, so that high-efficiency heat recovery is possible.

[0017] According to the invention described in claim 5, since a plurality of heat exchange fluid pipes to be heat-exchanged are provided in the heat exchange fluid circulation path, the heat exchange amount can be increased.

Modes for Carrying Out the Invention

[0019] Hereinafter, each embodiment of the present invention will be described in detail with reference to the drawings. [First Embodiment] First, a first embodiment according to the present invention will be described based on FIGS. 1 and 2.

[0020] FIG. 1 is a plan view showing a schematic configuration of a heat exchanger according to a first embodiment of the present invention. FIG. 2 is a longitudinal sectional view showing a schematic configuration of the heat exchanger according to this first embodiment.

[0021] In this first embodiment, an example will be described in which a high-temperature fluid is applied to a heat exchange fluid discharged by potential energy, and for example, feed water such as tap water is applied to a heat exchange fluid to be heated, which is lower in temperature than the high-temperature fluid and exchanges heat with the high-temperature fluid.

[0022] As shown in FIGS. 1 and 2, the heat exchanger 1 according to this first embodiment includes a heat exchanger main body 2 that is substantially circular in plan view.

[0023] The heat exchanger main body 2 has a heat exchange fluid circulation path 4 through which a heat exchange fluid circulates, and a heat exchange fluid to be heated, which is a low-temperature fluid lower in temperature than the heat exchange fluid and exchanges heat with the heat exchange fluid in a direction opposite to the flow direction of the heat exchange fluid through the heat exchange fluid circulation path 4, and a heat exchange fluid to be heated piping 5 through which the heat exchange fluid to be heated is supplied.

[0024] The heat exchange fluid circulation path 4 has, in plan view, a circulation path main body portion 40 formed in a spiral shape outward from the central position of the heat exchanger main body 2 by a cylindrical member.

[0025] The heat exchange fluid to be heated piping 5 is formed in a spiral shape along the inside of the heat exchange fluid circulation path 4 from the outer peripheral side of the heat exchanger main body 2 toward the central position of the heat exchanger main body 2.

[0026] At the central position of the heat exchanger main body 2, an inlet 41 is provided through which a heat exchange fluid that is discharged using potential energy and becomes high temperature through a discharge pipe 3 as a discharge means of a predetermined height flows in.

[0027] Note that this heat exchange fluid is, for example, high-temperature wastewater generated from a heat source such as a factory.

[0028] Furthermore, the heat exchange fluid discharge pipe 3 is configured to be detachable from the heat exchange device body 2.

[0029] Furthermore, the inlet 41 is connected to the outlet 42 through the heat exchange fluid circulation path 4. This outlet 42 is located on the outer periphery of the heat exchanger body 2.

[0030] Here, the entire heat exchange fluid circulation path 4 is filled with heat exchange fluid and has no air layer, so the entire outer surface of the heat exchange fluid piping 5 is constantly immersed in the heat exchange fluid within the heat exchange fluid circulation path 4.

[0031] Here, the inlet 41 is formed by an inlet forming portion 411 of a cylindrical member that extends above the circulation path main body portion 40, and this inlet forming portion 411 has a pipe outlet opening 41' at the upper end of its raised portion for bringing out and arranging the end of the heat exchange fluid piping 5.

[0032] Furthermore, the outlet 42 is formed by an outlet forming portion 421 that extends above the circulation path main body portion 40, and this outlet forming portion 421 has a pipe insertion opening 42' at the upper end of its raised portion for inserting and arranging the heat exchange fluid pipe 5.

[0033] Furthermore, the height of the outlet 42 is set lower than the predetermined height of the discharge pipe 3, which serves as the discharge means, and higher than the height of the circulation path main body 40, which is made of a cylindrical member.

[0034] Furthermore, two heat-exchange fluid pipes 5 are provided in the vertical direction. These two heat-exchange fluid pipes 5 are provided with a common supply port 51 inserted into the outlet 42 side of the heat-exchange fluid, and a common outlet 52 through which the heat-exchange fluid that has exchanged heat with the heat-exchange fluid is discharged.

[0035] Here, the heat-exchange fluid piping 5 is made of metal such as carbon steel, stainless steel, titanium, aluminum, or copper alloy, or it is made of rubber tubing, resin, etc.

[0036] Furthermore, the cylindrical members forming the main body 40 of the heat exchange fluid circulation path 4 are steel pipes, PVC pipes, etc.

[0037] Furthermore, the discharge pipe 3 extends from a heat source outside the heat exchanger body 2 and is arranged to discharge the heat exchange fluid to the upper part of the heat exchanger body 2. The heat exchange fluid piping 5 is arranged from the outer circumference of the heat exchanger body 2 through a spiral heat exchange fluid circulation path 4 toward its center, extends upward from this central position, and is configured to extend further to the outside of the heat exchanger body 2.

[0038] Next, the operation and effects of the heat exchange device 1 according to this first embodiment will be described.

[0039] First, the heat exchange fluid, which is a high-temperature fluid generated from a heat source such as a factory, is discharged by potential energy through the discharge pipe 3 to the inlet 41 located at the center of the heat exchange device body 2. The heat exchange fluid then flows into the main body 40 of the spiral-shaped heat exchange fluid circulation path 4. After flowing through the spiral-shaped main body 40 of the circulation path, it flows out from the outlet 42.

[0040] Meanwhile, the heat-exchange fluid is supplied from a supply port 51 inserted into the outlet 42 side of the heat-exchange fluid, and this heat-exchange fluid is discharged from an outlet 52 on the inlet 51 side through a spiral-shaped heat-exchange fluid piping 5 arranged along the heat-exchange fluid circulation path 4.

[0041] Here, the direction of the heat exchange fluid flowing through the heat exchange fluid circulation path 4 and the direction of the heat-exchanged fluid flowing through the heat-exchanged fluid piping 5 are opposite to each other, thus forming a perfect counterflow. The heat exchange fluid flows through a single heat exchange fluid circulation path 4, while the heat-exchanged fluid flows through the heat-exchanged fluid piping 5 in a single direction opposite to the flow of the heat exchange fluid, enabling heat recovery with high efficiency. Furthermore, since the entire outer surface of the heat-exchanged fluid piping 5 is constantly immersed in the heat exchange fluid within the heat exchange fluid circulation path 4, heat recovery becomes even more efficient.

[0042] Furthermore, since the heat exchange fluid is discharged through the discharge pipe 3 to the inlet forming section 411 by potential energy, a tank for storing the heat exchange fluid and a pump for supplying the heat exchange fluid become unnecessary.

[0043] As described above, according to the heat exchange device 1 of the first embodiment of the present invention, the circulation path body portion 40 of the heat exchange fluid circulation path 4 that constitutes the heat exchange device body 2 can be manufactured by a simple method such as bending a straight steel pipe or a cylindrical member such as a PVC pipe into a spiral shape. This allows for high manufacturing efficiency, and structurally, the material between adjacent heat exchange fluid circulation paths 4 can be omitted, thus keeping material costs low.

[0044] Furthermore, according to the heat exchange device 1 of this first embodiment, the height of the outlet 42 is set lower than a predetermined height of the discharge pipe 3 as a discharge means, and higher than the height of the circulation path main body 40 which is made of a cylindrical member. As a result, the heat exchange fluid that flows in from the inlet 41 always fills the heat exchange fluid circulation path 4, and after sufficient heat exchange has taken place between the heat exchange fluid and the fluid to be heat exchanged, it is discharged from the outlet 42. Therefore, heat can be recovered with high efficiency, the overall size of the heat exchange device 1 can be made compact, and a film of dirt is less likely to form on the surface of the fluid to be heat exchanged piping 5, so internal cleaning is hardly required.

[0045] Furthermore, according to the heat exchange device 1 of this first embodiment, in the heat-exchanged fluid piping 5, the heat-exchanged fluid to be exchanged with the heat-exchanged fluid is supplied in the opposite direction to the direction in which the heat-exchanged fluid flows in the heat-exchanged fluid circulation path 4, and the flow of the heat-exchanged fluid and the flow of the heat-exchanged fluid become opposing flows, thus enabling highly efficient heat recovery.

[0046] Furthermore, according to the heat exchange device 1 of this first embodiment, since multiple heat-exchange fluid pipes 5 (two in one example) are provided in the heat exchange fluid circulation path 4, the amount of heat exchange can be increased. [Second Embodiment] Next, a second embodiment of the present invention will be described based on Figure 3.

[0047] Figure 3 is a longitudinal cross-sectional view showing a schematic configuration of a heat exchanger according to a second embodiment of the present invention. In this second embodiment, parts that are the same as or corresponding to those in the first embodiment described above are denoted by the same reference numerals and their descriptions are omitted. Only the configurations and effects that differ from the first embodiment will be described.

[0048] In the heat exchange device 1 according to this second embodiment, as shown in Figure 3, the circulation path body portion 40 of the heat exchange circulation path 4 is formed of a rectangular tubular member rather than a cylindrical member.

[0049] According to the heat exchanger 1 of this second embodiment, the installation surface of the heat exchanger 1 can be made flat and large, allowing for more stable installation. [Third Embodiment] Next, a third embodiment of the present invention will be described based on Figures 4, 5, and 6.

[0050] Figure 4 is a plan view showing the schematic configuration of a heat exchanger according to the third embodiment of the present invention. Figure 5 is a longitudinal cross-sectional view showing the schematic configuration of the heat exchanger according to this third embodiment. Figure 6 is a partially enlarged longitudinal cross-sectional view showing an enlarged view of a part of the longitudinal cross-section of the heat exchange fluid circulation path of the heat exchanger according to this third embodiment. In this third embodiment, parts that are the same as or corresponding to those in the first embodiment described above are denoted by the same reference numerals and their descriptions are omitted, and only the configurations and effects that differ mainly from the first embodiment will be described.

[0051] In the heat exchange device 1 according to this third embodiment, as shown in Figures 4, 5, and 6, the circulation path body 40 of the heat exchange fluid circulation path 4 through which the heat exchange fluid flows is not a cylindrical member, but rather a semicircular groove-shaped member with an open top surface, which is formed in a spiral shape in plan view.

[0052] In this third embodiment of the heat exchanger 1, the height of the outlet 42 is set to be less than the height of the circulation path main body 40.

[0053] According to the heat exchanger 1 of this third embodiment, for example, the circulation path body portion 40 of the heat exchange fluid circulation path 4 that constitutes the heat exchanger body 2 can be manufactured by a simple method such as bending a straight cylindrical member into a spiral shape and then dividing it in half in the cross-sectional direction. This increases manufacturing efficiency, and structurally, it is possible to omit material between adjacent heat exchange fluid circulation paths 4, thus keeping material costs low.

[0054] Furthermore, the circulation path body 40 of the heat exchanger 1 according to this third embodiment may be manufactured by dividing a straight cylindrical member in half in the cross-sectional direction and then bending it to form a spiral shape.

[0055] Furthermore, the circulation path body 40 of the heat exchanger 1 according to this third embodiment can also be manufactured by casting or the like.

[0056] Furthermore, according to the heat exchange device 1 of this third embodiment, the inside can be easily cleaned from the upper opening of the heat exchange fluid circulation path 4.

[0057] Furthermore, in the heat exchange device 1 according to this third embodiment, as shown by the dashed line in Figure 6, by sealing the upper opening of the heat exchange fluid circulation path 4 with a cover member 6, the height of the outlet 42 can be set lower than the predetermined height of the discharge pipe 3 as a discharge means and higher than the height of the circulation path body 40, similar to the heat exchange device 1 according to the first embodiment. In this case, the heat exchange fluid flowing in from the inlet 41 always fills the heat exchange fluid circulation path 4, and after sufficient heat exchange has taken place between the heat exchange fluid and the fluid to be heat exchanged, it is discharged from the outlet 42, so that heat can be recovered with high efficiency, the overall size of the heat exchange device 1 can be made compact, and a film of dirt is less likely to form on the surface of the fluid to be heat exchanged piping 5, so internal cleaning is hardly required. [Fourth Embodiment] Next, a fourth embodiment of the present invention will be described based on Figures 7 and 8.

[0058] Figure 7 is a longitudinal cross-sectional view showing a schematic configuration of a heat exchanger according to the fourth embodiment of the present invention. Figure 8 is a partially enlarged longitudinal cross-sectional view showing an enlarged view of a portion of the longitudinal cross-section of the heat exchange fluid circulation path of the heat exchanger according to this fourth embodiment. In this fourth embodiment, the same or corresponding parts as those in the first and third embodiments described above are denoted by the same reference numerals and their descriptions are omitted. Only the configurations and effects that differ from those in the first and third embodiments will be described.

[0059] In the heat exchanger 1 according to this fourth embodiment, as shown in Figures 7 and 8, the circulation path body 40 of the heat exchange fluid circulation path 4 through which the heat exchange fluid flows is not a semicircular groove-shaped member with an open top, but rather a semi-square groove-shaped member with an open top, which is formed in a spiral shape in plan view.

[0060] In this fourth embodiment of the heat exchange device 1, similar to the third embodiment of the heat exchange device 1, the height of the outlet 42 is set to be less than the height of the circulation path main body 40.

[0061] According to the heat exchanger 1 of this fourth embodiment, for example, the circulation path body portion 40 of the heat exchange fluid circulation path 4 that constitutes the heat exchanger body 2 can be manufactured by a simple method such as bending a straight rectangular tubular member into a spiral shape and then dividing it in half in the cross-sectional direction. This increases manufacturing efficiency, and structurally, it is possible to omit material between adjacent heat exchange fluid circulation paths 4, thus keeping material costs low.

[0062] Furthermore, according to the heat exchange device 1 of this fourth embodiment, the installation surface of the heat exchange device 1 can be made flat and large, allowing for more stable installation.

[0063] Furthermore, the circulation path body 40 of the heat exchanger 1 according to this fourth embodiment may be manufactured by dividing a straight rectangular tubular member in half in the cross-sectional direction and then bending it to form a spiral shape.

[0064] Furthermore, the circulation path body 40 of the heat exchange device 1 according to this fourth embodiment can also be manufactured by casting or the like, similar to the heat exchange device 1 according to the third embodiment.

[0065] Furthermore, in this fourth embodiment of the heat exchange device 1, similar to the heat exchange device 1 according to the third embodiment, if the upper opening of the heat exchange fluid circulation path 4 is sealed with a cover member 6 as shown by the dashed line in Figure 8, the height of the outlet 42 can be set lower than the predetermined height of the discharge pipe 3 as a discharge means and higher than the height of the circulation path body 40, similar to the heat exchange device 1 according to the first embodiment. In this case, the heat exchange fluid flowing in from the inlet 41 always fills the heat exchange fluid circulation path 4, and after sufficient heat exchange has taken place between the heat exchange fluid and the fluid to be heat exchanged, it is discharged from the outlet 42, so that heat can be recovered with high efficiency, the overall size of the heat exchange device 1 can be made compact, and a film of dirt is less likely to form on the surface of the fluid to be heat exchanged piping 5, so internal cleaning is hardly required.

[0066] The embodiments described above are merely examples of the present invention, and it goes without saying that the present invention is not limited to these embodiments. In other words, the specific configurations and procedures of the above embodiments can be modified in various ways without departing from the spirit of the present invention.

[0067] For example, in the embodiment described above, a high-temperature fluid was applied as the heat exchange fluid, and a low-temperature fluid to be heat-exchanged was applied to exchange heat with the high-temperature fluid. However, the embodiment is not limited to this, and it may also be carried out by applying a low-temperature fluid as the heat exchange fluid, and a high-temperature fluid to be heat-exchanged was applied to exchange heat with the low-temperature fluid.

[0068] Furthermore, in the embodiments described above, the cross-sectional shapes of the members constituting the circulation path body were cylindrical, rectangular, semicircular groove with an open top, and semi-square groove with an open top, but the invention is not limited to these, and other shapes may be used.
