Description

[Technical field]

[0001] The present invention relates to a steam-driven pump device that can utilize steam (saturated steam) generated from a boiler facility as a power source and a heat source, and more particularly, to a steam-driven pump device that can fully utilize the high potential of steam. [Background technology]

[0002] The uses of steam can be broadly divided into two main categories: as a heat source for heating, humidification, etc., and as a power source. In the past, "steam" was synonymous with steamships, land steam meant steam locomotives, and steam hammers meant automatic steam hammers, a power source for forging and other processes. Nowadays, steam is used more as a heat source for heating, humidification, etc. than as a power source. The range of applications of steam as a heat source for heating, humidification, etc. is expanding beyond the industrial sector, to include household steam ovens and steam cleaners. In many cases, steam is used in the form of saturated steam, as it is easy to use because the relationship between pressure and temperature is constant, and it can be heated quickly by latent heat heating.

[0003] Steam is usually generated by boiler equipment. The pressure of steam used in factories is usually 0.1MPa to 5MPa, and the temperature of steam is usually about 110℃ to 250℃. Boilers used in factories are usually set to supply the highest pressure required within the factory, but depending on the application, the high-pressure steam generated in the boiler may be too high. Therefore, a pressure reducer is installed in the middle of the piping to reduce the steam pressure before use. In this way, high-pressure steam is used by deliberately reducing the pressure, and it was thought that it would be good if the high potential of steam could be fully utilized. In short, it was thought that it would be good to have a device that could make the most of the energy of steam without reducing the pressure.

[0004] Patent Document 1 discloses a power generation method that utilizes water vapor pressure, saying, "A rice husk combustor is used to burn a fuel mixture of rice husks and chip dust to generate water vapor, and the generated water vapor is sprayed from the steam nozzle of the device of the present invention onto a rotor, causing the rotor to start rotating. At this time, the rotor is subjected to water vapor pressure from inside one of the cylinders. Furthermore, in the other cylinder, the water vapor used in the previous process is simultaneously discharged from an exhaust hole. Continuous rotational power is generated by carrying out such processes in the left and right cylinders. Continuous power generation is achieved by linking the generated power to a generator." (Patent Document 1: Title of the Invention) [Prior art documents] [Patent documents]

[0005] [Patent Document 1] JP 2018-080692 A Summary of the Invention [Problem to be solved by the invention]

[0006] The power generation method using steam pressure according to Patent Document 1 (Patent Document 1: Title of the invention) has circular cylinders on the left and right sides of a cylinder block, with a rotor installed inside the circular cylinder so that it moves, and when the rotor receives steam pressure on its circumferential surface, the rotor moves while rotating inside the circular cylinder, rotating the crankshaft, thereby obtaining power for generating electricity. Although it uses steam as a power source, it is not possible to utilize the heat source of the steam. Furthermore, it does not fully utilize the potential of steam.

[0007] The object of the present invention is to provide a steam-driven pump device that can utilize steam (saturated steam) generated from a boiler facility as both a power source and a heat source, and further, to fully utilize the high potential of steam, in other words, to maximize the energy of steam without reducing its pressure. [Means for solving the problem]

[0008] In order to solve the above problems, the invention described in claim 1 is a steam-driven pump device that uses steam pressure supplied from a boiler as a power source, the steam-driven pump device comprising: a housing member that forms the outer shell of the device; a rotating shaft with a spiral fin that is installed by penetrating the housing member; a cylindrical body with a spiral fin that is installed with the rotating shaft with the spiral fins penetrating it and has spiral fins on both the inside and outside; a cylindrical body with an open type three-dimensional curved surface that is installed on one side of the rotating shaft with the spiral fin and has an inlet and an outlet that rotates under the steam pressure supplied from the boiler, the cylindrical body having a plurality of steam pressure receiving members whose inlet side cross-sectional area is 50 to 100 times the outlet side cross-sectional area; Pressure A water vapor receiving member housing for housing a receiving member, and a cylindrical body with a spiral fin and the water vapor receiving member housing boundary A rotating member to be installed on the A rotating shaft having a spiral fin is provided on the other side of the rotating shaft. Decoration the fluid to be heated is sucked in from outside the device, inside the housing member and outside the spiral finned cylinder, and the water vapor pressure receiving member is installed so as to inject water vapor into the spiral finned cylinder, the water vapor pressure receiving member injects water vapor into the spiral finned cylinder, and the water vapor passes through the spiral finned cylinder and is discharged to the outside of the housing, making it a steam-driven pump device.

[0009] The invention described in claim 2 is characterized in that, in the invention described in claim 1, the housing member is a steam-driven pump device having a plurality of annular fin members protruding inwardly.

[0010] The invention described in claim 3 is characterized in that, in the invention described in claim 1 or claim 2, the water vapor receiving member housing is a steam-driven pump device having radial rotary fin members protruding outward. Effect of the Invention

[0011] The steam-driven pump device of the present invention can utilize steam (saturated steam) generated in a boiler as both a power source and a heat source, making it possible to fully utilize the high potential of steam, in other words, to provide a device that can make maximum use of the energy contained in steam without reducing the pressure.

[0012] Characteristically, by installing the water vapor receiving member housing so as to surround the water vapor receiving member (leaving as few gaps as possible) (by improving the airtightness), it has become possible to use much of the water vapor supplied from the outside as a power source. And, by using the cylindrical body with spiral fins and the radial rotary fin members installed on the outside of the water vapor receiving member housing, heat dissipation (heat exchange) can be performed efficiently and smoothly, making it possible to more effectively utilize the thermal energy of the water vapor. Furthermore, by installing a rotating member with a sealing function at the interface between the cylindrical body with spiral fins and the water vapor receiving member housing, it has become possible to stabilize the rotation of the water vapor receiving member, especially during high-speed rotation.

[0014] <Structure of steam-driven pump device> Hereinafter, an embodiment of a steam-driven pump device 10 according to the present invention will be described in detail with reference to Figs. 1 to 7. Fig. 1 is an overall cross-sectional view of the steam-driven pump device 10 according to the present invention. The steam-driven pump device 10 is a steam-driven pump device 10 that uses (high-pressure) steam supplied from a boiler as a power source and can supply hot water (which may be warm water) by using the steam as a heat source. As shown in Fig. 1, the steam-driven pump device 10 includes a housing member 30 that forms an outer shell. In Fig. 1, a space (which may be something like a water tank) for storing a fluid to be heated (where a flow occurs when the steam-driven pump device 10 is operated) is further shown to cover the periphery of the steam-driven pump device 10 (housing member 30) so that the installation state of the steam-driven pump device 10 can be understood.

[0015] Inside the housing member 30, there are a rotating shaft with spiral fins 40 (see FIG. 2 for detailed shape) that penetrates the housing member 30, a cylindrical body with spiral fins 50 that is installed with the rotating shaft with spiral fins 40 penetrating it (the cylindrical body with spiral fins 50 is provided with an inner spiral fin 51 installed inside the cylindrical body with spiral fins 50, and an outer spiral fin 52 installed outside the cylindrical body with spiral fins 50. See FIG. 4 for detailed shape of the cylindrical body with spiral fins 50), and a plurality of steam pressure receiving parts (approximately 3 to 5) that are installed on one end side of the rotating shaft with spiral fins 40 and rotate under steam pressure supplied from a boiler. The device comprises a material 60, a water vapor receiving member storage body 61 having radial rotating fin members 90 (see Figure 5 for detailed shape) that protrude outward for storing the water vapor receiving member 60, a rotating member 62 (ring-shaped bearing) with a sealing function that is fixedly attached to the water vapor receiving member storage body 61 at the boundary between the cylindrical body 50 with spiral fins and the water vapor receiving member storage body 61, and a propulsion screw member 70 that is installed on the other end side of the rotating shaft 40 with spiral fins and sucks the heated fluid from outside the device into the inside of the housing member 30, outside the cylindrical body 50 with spiral fins and the water vapor receiving member storage body 61, and sends it out to the outside of the device.

[0016] Furthermore, the housing member 30 is provided with a plurality of annular fin members 80 that protrude inward. The tip portions of the annular fin members 80 are disposed in a state where they fit into the gaps between the spiral fin portion (outer spiral fin 52) protruding from the spiral-finned cylinder body 50 (see FIG. 1).

[0017] In this specification, the "fins" in the annular fin member 80, the spiral finned cylinder 50, the radial rotary fin member 90, etc. refer to "fins" attached to flat plates, pipes, etc. constituting a heat exchanger, radiator, etc., to increase the heat transfer area and the amount of heat transferred. There are various types of "fins", such as straight fins, annular fins, and spiral fins.

[0018] Fig. 2(a) is an overall view of the rotating shaft with helical fins 40, the water vapor pressure receiving member 60, the rotating member with a sealing function 62, and the propulsion screw member 70 of the steam-driven pump device 10, and Fig. 2(b) is a diagram for explaining the behavior of water vapor in the water vapor pressure receiving member 60. As shown in Fig. 2(a), the water vapor pressure receiving member 60 is installed on one side of the rotating shaft with helical fins 40, and the propulsion screw member 70 is installed on the other side. The rotating shaft with helical fins 40, the water vapor pressure receiving member 60, the rotating member with a sealing function 62, and the propulsion screw member 70 are all configured to rotate in conjunction with each other.

[0019] As shown in Fig. 2(b), the shape of the water vapor pressure receiving member 60 can be said to be a freely bent cylindrical body. In short, the water vapor pressure receiving member 60 is an open type member having an inlet face and an outlet face (the angle between the inlet face and the outlet face can be freely selected), a cylindrical body having a three-dimensional curved surface connecting the inlet face and the outlet face, and is characterized in that the cross-sectional area of ​​the inlet face side that receives water vapor is larger than the cross-sectional area of ​​the outlet face side that discharges water vapor. Numerically, it is preferable that the cross-sectional area of ​​the inlet side is 50 to 100 times the cross-sectional area of ​​the outlet side.

[0020] The action of the propulsion screw member 70 can be explained by the screw principle. The screw principle is a propulsion device that rotates in a fluid to generate a flow of the fluid in the direction of the rotation axis, and the blades are formed so that the rotation of the propulsion screw member 70 generates a flow in which the heated fluid is sucked from the outside of the housing member 30 of the steam-driven pump device 10 according to the present invention into the space inside the housing member 30, the outside of the cylindrical body 50 with spiral fins, and the outside of the water vapor receiving member storage body 61 (see FIG. 1).

[0021] <Drive system for steam-driven pump device> Fig. 3 is a diagram for explaining the driving principle of the steam-driven pump device 10 according to the present invention. As shown in Fig. 3, the steam-driven pump device 10 receives steam (high-pressure steam: see Fig. 3) introduced from outside the steam-driven pump device 10 through a steam inlet, i.e., steam injected from a boiler as a generation source, through a steam pressure receiving member 60 that is rotatably installed (see Fig. 2(b)). When the steam pressure receiving member 60 rotates, the rotating shaft 40 with the spiral fins connected to the steam pressure receiving member 60 rotates. When the rotating shaft 40 with the spiral fins connected to the steam pressure receiving member 60 rotates using steam pressure as a power source, the driving screw member 70 that is coaxial with the rotating shaft 40 with the spiral fins also rotates in conjunction with the rotation.

[0022] When the propulsion screw member 70 also rotates in conjunction, as shown in Figure 3, the fluid to be heated (water, a coolant liquid mainly composed of ethylene glycol, etc.) filled in the space (water tank, etc.) for storing the heated fluid formed to cover the periphery of the housing member 30 is sucked from the space (water tank, etc.) for storing the heated fluid formed to cover the periphery of the housing member 30 into the space inside the housing member 30, formed by the outside of the spiral finned cylindrical body 50 and the outside of the water vapor receiving member storage body 61, as shown by the arrow in Figure 3.

[0023] At the same time, the water vapor ejected from the water vapor pressure receiving member 60 (passing through the water vapor pressure receiving member 60 while rotating) enters the inside of the cylindrical body with spiral fins 50. Due to the action of the rotating shaft with spiral fins 40 and the spiral fins 51 provided inside the cylindrical body with spiral fins 50, the water vapor that entered the cylindrical body with spiral fins 50 does not pass straight through, and the flow of the water vapor basically exhibits a spiral behavior (shown by arrows in FIG. 3), and in addition to the spiral behavior, turbulence is also generated. In short, if the water vapor that entered the cylindrical body with spiral fins 50 passes straight through the cylindrical body with spiral fins 50, the heat quantity of the water vapor cannot be sufficiently transferred, so the water vapor is designed to remain inside the cylindrical body with spiral fins 50 for as long as possible. Thereafter, the water vapor that has entered the inside of the spirally finned cylinder 50 is finally discharged to the outside of the steam-driven pump device 10. (In FIG. 3, this is indicated as return steam.)

[0024] <Heat exchange function of steam-driven pump equipment> Fig. 4 is a cross-sectional view of the water vapor receiving member housing 61 and the spiral finned cylindrical body 50. Fig. 5 is a diagram for explaining the radial rotary fin member 90. The heat exchange function of the steam driven pump device 10 according to the present invention will be described with reference to Figs. 4 and 5.

[0025] In the steam-driven pump device 10, the heat of the water vapor that collides with the inner wall of the spiral finned cylinder 50 (including the inner spiral fin 51) and the inner wall of the water vapor receiving member storage body 61, in other words, the heat of vaporization (latent heat) of the water vapor as a heat source, is transferred through the spiral finned cylinder 50 (including the outer spiral fin 52) and the radial rotary fin member 90 (installed so as to protrude outside the water vapor receiving member storage body 61: see Figure 5) to the heated fluid (water, a coolant liquid mainly composed of ethylene glycol, etc.) that has been sucked into the space formed inside the inner housing member 30 by the outside of the spiral finned cylinder 50 and the outside of the water vapor receiving member storage body 61, thereby heating the heated fluid (water, a coolant liquid mainly composed of ethylene glycol, etc.).

[0026] The flow of the heated fluid inside the housing member 30 of the steam driven pump device 10 will be explained. The heated fluid (water, ethylene glycol-based coolant, etc.) drawn into the space inside the housing member 30 formed by the outside of the spiral finned cylinder 50 and the outside of the water vapor receiving member housing 61 flows upward from below, rotating in a spiral manner between the fins of the spiral finned cylinder 50 (in other words, the outer spiral fins 52), and flows between the fins of the radial rotary fin member 90 installed so as to protrude outside the water vapor receiving member housing 61 (see Figs. 4 and 5). The heated fluid (water, ethylene glycol-based coolant, etc.) is finally pushed out to the outside of the steam driven pump device 10.

[0027] Furthermore, as a device for making it easier for the heated fluid (water, a coolant liquid mainly composed of ethylene glycol, etc.) to receive heat from the water vapor, the housing member 30 is provided with a plurality of annular fin members 80 that protrude inward (see FIG. 1). Since the housing member 30 is provided with the annular fin members 80, the flow of the heated fluid (water, a coolant liquid mainly composed of ethylene glycol, etc.) must pass near the cylindrical body 50 with the spiral fins (see FIG. 3).

[0028] Therefore, it will take longer for the heated fluid to pass through the space formed by the inside of the inner housing member 30, the outside of the spiral finned cylindrical body 50, and the outside of the water vapor receiving member storage body 61, but the longer this time, the more heat that can be absorbed from the water vapor via the spiral finned cylindrical body 50, and the more efficiently the temperature of the heated fluid can be raised.

[0029] FIG. 6 is a diagram for explaining the rotation of the water vapor pressure receiving member 60 and the state of water vapor injection. As shown in FIG. 6, when the water vapor pressure receiving member 60 receives water vapor (indicated by arrow c), the water vapor pressure receiving member 60 rotates around the rotating shaft 40 with spiral fins (indicated by arrow a). Then, (because the injection source rotates), the water vapor injected from the water vapor pressure receiving member 60 is injected while rotating around the rotating shaft 40 with spiral fins (the injected water vapor is affected by centrifugal force). Therefore, since it takes more time for the water vapor to pass through the inside of the cylindrical body 50 with spiral fins than when the water vapor is injected without rotating the water vapor pressure receiving member 60, in other words, when the injection source is fixed, the residence time of the water vapor in the cylindrical body 50 with spiral fins is longer accordingly, and the heat contained in the water vapor can be conducted to the cylindrical body 50 with spiral fins without waste.

[0030] The steam injected from the steam pressure receiving member 60 is injected while rotating around the rotating shaft 40 with the spiral fins. If the injected steam is considered as an injection vector (indicated by arrow b), the vector component (indicated by arrow d) that is parallel to the vector (indicated by arrow c) by which the steam pressure receiving member 60 receives the steam acts as a component that contributes to the rotation (in other words, contributes to the rotation by acting as a reverse injection). Since the injected steam contributes to the rotation of the rotating shaft 40 with the spiral fins, the pressure of the steam can be used more efficiently as rotational energy. The angle between the inlet and outlet faces of the steam pressure receiving member 60 can be freely selected, but it is desirable that the angle be 80° to 100° from the viewpoint of efficiently using the pressure of the steam as rotational energy.

[0031] <Specific examples of use of steam-driven pump devices> Fig. 7 is a diagram for explaining a specific example of use of the steam driven pump device 10. There are thought to be many uses and applications of the steam driven pump device 10 according to the present invention, but here, a case where the steam driven pump device 10 according to the present invention is used in a hot water supply system in a high-rise building or the like will be explained. The steam driven pump device 10 completely changes conventional hot water supply systems (hot water supply methods), and will fundamentally transform hot water supply methods in high-rise buildings and the like.

[0032] During operation of the steam driven pump device 10, the heated fluid is heated and discharged outside the steam driven pump device 10 to be supplied to a water heater or the like, and then a new heated fluid is supplied to the steam driven pump device 10, or the heated fluid that has completed its task of floor heating, snow melting, or the like returns, replenishing the space for storing the heated fluid that is formed outside the steam driven pump device 10 and covers the periphery of the housing member 30. By repeating this flow, the steam driven pump device 10 can continue to supply hot water (warm water) to the outside.

[0033] As shown in the left diagram of Figure 7, the conventional hot water supply method generally involves installing a hot water storage tank (also called a storage tank, which usually has a water heating function) on the roof of a high-rise building and supplying water (using gravity) to each floor. With this method, installation costs are incurred, as a hot water storage tank must be installed on the roof of a high-rise building. Furthermore, there are costs associated with maintaining the hot water supply equipment, including the storage tank. There is also the issue of the costs involved in having the storage tank pass annual statutory inspections.

[0034] In contrast, with a hot water supply system using the steam driven pumping equipment 10 of the present invention, as shown in the right diagram of Figure 7, installation can be completed simply by installing the boiler equipment on the ground, installing the steam driven pumping equipment 10 on each floor, and running the piping between the boiler equipment and the steam driven pumping equipment 10.

[0035] The steam-driven pumping device 10 utilizes the inherently high potential of steam pressure to directly supply steam to the steam-driven pumping device 10 installed on each floor, and the steam-driven pumping device 10 installed on each floor operates the steam-driven pumping device 10 using the steam supplied from the boiler equipment as a power source, and furthermore, uses the steam as a heat source to boil hot water (or warm water) and supply hot water to each floor. With this method, there is no installation cost and the maintenance cost can be kept low.

[0036] <Effects of steam-driven pumping device> The steam-driven pump device 10 according to the present invention utilizes water vapor generated by a boiler facility. The steam-driven pump device 10 can use water vapor (generated in a boiler) as both a power source and a heat source, and furthermore, the greatest feature of the steam-driven pump device 10 is that it is possible to provide a steam-driven pump device 10 that can fully utilize the high potential of water vapor, in other words, can make maximum use of the energy contained in water vapor without reducing its pressure.

[0037] As shown in Fig. 4, the heated fluid flows upward from below, rotating in a spiral between the inner housing member 30 and the fin portion of the spiral finned cylinder 50 (the flow of the heated fluid is shown in Fig. 4). That is, the presence of the fin portion of the spiral finned cylinder 50 and the water vapor receiving member container 61 equipped with radial rotary fin members (see Fig. 5) protruding outward can increase the heat transfer area of ​​the heated fluid and the amount of heat transfer.

[0038] Furthermore, by installing the water vapor receiving member housing 61 so as to surround the water vapor receiving member 60 (leaving as few gaps as possible) and by installing a rotating member with a sealing function at the boundary surface between the spiral finned cylinder and the water vapor receiving member housing to improve the sealed state, it is possible to convert much of the injected water vapor into rotational energy and to stabilize the rotational state of the water vapor receiving member 60 even when the water vapor receiving member 60 rotates at high speed. Therefore, it has become possible to provide a steam-driven pump device 10 that can make maximum use of the energy contained in the water vapor without reducing the pressure.

[0039] Furthermore, due to the action of the spiral finned rotating shaft 40 and the spiral fins 51 provided inside the spiral finned cylinder 50, the water vapor that has entered the spiral finned cylinder 50 does not pass straight through, but the flow of water vapor basically exhibits a spiral behavior (shown by arrows in FIG. 3), and in addition to the spiral behavior, turbulence is also generated. Therefore, by making efforts to ensure that the water vapor that has entered the spiral finned cylinder 50 remains inside the spiral finned cylinder 50 for as long as possible, heat dissipation (heat exchange) can be performed smoothly and efficiently.

[0040] If the steam-driven pump device 10 according to the present invention is used as a hot water supply system for a high-rise building, as shown in Fig. 7, a boiler facility can be installed on the ground, and steam can be directly supplied to each floor by utilizing the momentum of the high potential steam pressure (without the need to reduce the pressure by using a pressure reducing valve), and the steam-driven pump device 10 installed on each floor can use the steam as a heat source to boil hot water and supply it to each floor. This system does not require installation costs, and the maintenance costs can be kept low. It can be used not only for hot water supply systems in high-rise buildings, but also for floor heating systems (in high-rise buildings), and can also be used as a snow melting device to melt snow on the roof.

[0041] <Example of modification of steam-driven pump device> The steam-driven pump device of the present invention is not limited to the aspects of the above-mentioned embodiments, and the configurations of the housing member, rotating shaft, cylindrical body with spiral fins, inner spiral fins, outer spiral fins, water vapor pressure receiving member, water vapor receiving member storage body, rotating member with sealing function, propulsion screw member, annular fin member, radial rotary fin member, etc. can be appropriately modified as necessary within the scope of the spirit of the present invention. [Industrial Applicability]

[0042] Since the steam-driven pump of the present invention has the excellent effects as described above, it can be suitably used as a steam-driven pump device that can utilize water vapor (saturated steam) generated in a boiler as both a power source and a heat source, and can be used not only in hot water supply systems for high-rise buildings, but also in underfloor heating systems and snow-melting devices.
