Description

Technical Field

[0001] This invention relates to the field of thermal storage equipment, and more particularly to a water distributor for a thermal storage tank. Background Technology

[0002] Patent publication CN112524671B discloses a heat storage system that requires the use of a heat storage tank. This type of heat storage tank has two outlets, one at the top and one at the bottom. Hot water enters and exits through the outlet at the top of the tank, while cold water enters and exits through the outlet at the bottom. Because this heat storage tank adopts a vertical structure, when the hot water leaves the outlet at the top of the tank, the hot water at the top of the tank leaves the tank, while the cold water at the bottom of the tank continuously rises (during which an external water pump continuously pumps cold water into the tank). Due to the three-dimensional structure of the heat storage tank, the water pump needs to withstand high water pressure during the process of pressing (also known as pumping) the cold water into the tank (that is, the process of pushing the hot water out of the tank from the top), and the head requirement of the water pump is also relatively high. Summary of the Invention

[0003] To address the above-mentioned problems, this invention proposes a heat storage tank water distributor.

[0004] The technical solution adopted in this invention is as follows:

[0005] A heat storage tank water distributor includes a tank body and a support. The tank body is cylindrical, and the support is disposed on the tank body for contacting the ground. The tank body has multiple first openings and multiple second openings. When the support is in contact with the ground, the first openings are located above the tank body, and the second openings are located below the tank body. The central axis of the tank body is parallel to the ground.

[0006] This type of thermal storage tank water distributor adopts a horizontal arrangement (i.e., the central axis inside the tank is parallel to the ground). Although the horizontal arrangement increases the overall footprint of the thermal storage tank, it significantly reduces the water pressure inside the tank (especially at the bottom). This significantly reduced water pressure lowers the requirements for the tank's sealing strength, thus greatly reducing the probability of leakage. The significantly lower water pressure also greatly reduces the likelihood of the tank bursting. Furthermore, the relatively lower water pressure inside the tank (compared to a vertical arrangement) means that even if the tank bursts, the distance the water splashes out is relatively short, significantly reducing the required pump head.

[0007] In summary, the horizontal arrangement of the water distributor in this thermal storage tank reduces the water pressure inside the tank, thereby lowering the probability of tank rupture.

[0008] When the water distributor of this thermal storage tank is in use, high-temperature water enters the tank through the first opening and exits the tank through the first opening, while low-temperature water enters the tank through the second opening and exits the tank through the second opening.

[0009] Optionally, it also includes a partition, which is disposed inside the tank. There are multiple partitions, and the partitions are provided with through holes. The partitions divide the internal space of the tank into multiple independent and interconnected water storage chambers. Each water storage chamber is provided with a first opening and a second opening.

[0010] In this solution, a circular, metal-made baffle is installed inside the tank. The baffle, along with the tank body, is attached tightly to the inner wall of the tank. The baffle divides the space inside the tank into several independent but interconnected water storage chambers. Water in two adjacent water storage chambers can flow through the through holes in the baffle. When the tank bursts somewhere, and the burst point is located in a water storage chamber, the water inside the tank will not flow out from the burst opening all at once due to the separation and water-blocking effect of the baffle. This slows down the rate at which water flows out of the tank, thus providing more escape time for on-site personnel.

[0011] Optionally, it also includes a sleeve rod, wherein the partition plate is slidably engaged with the inner wall of the tank, the sleeve rod is disposed inside the tank and parallel to the central axis of the tank, the partition plate is slidably sleeved on the sleeve rod through its own through hole, a limit ring is fixedly disposed on the sleeve rod, and the limit ring is disposed on both sides of the partition plate, and the sleeve rod is parallel to the central axis of the tank.

[0012] Specifically, the two ends of the sleeve are fixed to the two planar end faces of the tank. The sleeve is parallel to the central axis of the tank, while the baffle is perpendicular to the central axis of the tank. Limiting rings are set on both sides of the baffle, and the baffle can slide between the two limiting rings. In this way, when the tank bursts and water flows out of the tank, the water flow formed in the tank may cause the baffle to move in the tank and rub against the inner wall of the tank. The inner wall of the tank may generate a low-frequency noise similar to a buzzing sound during the process of being rubbed by the baffle. This can serve as a warning to the on-site workers. At the same time, the sliding nature of the baffle can also slow down the speed of water outflow to a certain extent.

[0013] Optionally, it also includes a buffer and a temporary storage unit, wherein the second opening of the tank is connected to the buffer and the first opening of the tank is connected to the temporary storage unit.

[0014] Specifically, water flows in and out between the tank and the buffer through the second opening, and between the tank and the temporary storage device through the first opening. The function of both the buffer and the temporary storage device is to smooth the water flow, ensuring that the tank experiences as little vibration as possible during the flow of water in and out of the tank.

[0015] Optionally, it also includes a slide rod, a first stop block, and a second stop block. The temporary storage device has an exhaust hole, which is a frustum-shaped exhaust hole. The wide opening of the exhaust hole is located inside the temporary storage device, and the narrow opening of the exhaust hole is located outside the temporary storage device. The slide rod is a frustum-shaped slide rod that slides together with the exhaust hole. The first stop block and the second stop block are both disposed on the slide rod. The first stop block is located inside the temporary storage device, and the second stop block is located outside the temporary storage device. A sealing ring is disposed on the inner wall of the temporary storage device. The sealing ring is used to contact the first stop block. The density of the slide rod, the density of the first stop block, and the density of the second stop block are all less than that of water.

[0016] Specifically, the sliding rod, the first stop, and the second stop are all made of polypropylene plastic (the hot melt temperature of polypropylene is around 150℃, and the water temperature inside the tank does not exceed 80℃). In the above structure, when the water in the temporary storage container contains air bubbles, the air bubbles surge back towards the vent. At this time, since the water is no longer in contact with the sliding rod and the first stop, the first stop, under its own gravity, causes the sliding rod to fall, and the air bubbles escape from the vent. Then the water level rises again, causing the sliding rod to float up. The sliding rod then presses against the vent and seals the vent. The sealing ring is set on the inner wall of the temporary storage container to further increase and improve the sealing performance.

[0017] Optionally, the buffer has a buffer inlet and outlet, the temporary storage has a temporary storage inlet and outlet, and a transparent tube is connected to both the buffer inlet / outlet and the temporary storage inlet / outlet. A ring-shaped light strip is fitted onto the transparent tube.

[0018] Because the water entering the tank (including the temporary storage and buffer) may come from municipal tap water, which contains hypochlorous acid, a highly corrosive acid (extremely corrosive to various rubber sealing components), transparent tubes are connected to the inlet and outlet of the buffer and the inlet and outlet of the temporary storage. Water flows through these transparent tubes, and a ring-shaped LED strip on the tube emits ultraviolet light to irradiate the water, causing the hypochlorous acid to degrade into hydrogen chloride, which is more corrosive. The small amount of oxygen produced during the degradation process is eventually released through the vent.

[0019] Optionally, it also includes a temperature measuring rod, on which multiple water temperature sensors are provided, and two adjacent water temperature sensors on the temperature measuring rod do not contact each other. The temperature measuring rod is set on the tank body, and all the water temperature sensors on the temperature measuring rod are located inside the tank body.

[0020] Each temperature probe is equipped with multiple water temperature sensors. The temperature probe is placed on the tank, and the water temperature sensors are located inside the tank. This allows for temperature detection in every corner of the tank.

[0021] Optionally, a pressure probe is provided on the tank.

[0022] There are multiple pressure probes, and each water storage chamber has one of them. The function of the pressure probes is to detect the water pressure inside the tank.

[0023] The beneficial effects of this invention are: by adopting a horizontal arrangement structure, the water pressure inside the tank is reduced, thereby reducing the probability of the tank bursting. Attached image description:

[0031] The present invention will now be described in detail with reference to the accompanying drawings.

[0032] As attached Figure 1 and appendix Figure 3 As shown, a heat storage tank water distributor includes a tank body 2 and a support (not shown in the attached drawing). The tank body 2 is cylindrical, and the support is mounted on the tank body 2 for contact with the ground. The tank body 2 has multiple first openings 201 and multiple second openings 202. When the support is in contact with the ground, the first openings 201 are located above the tank body 2, and the second openings 202 are located below the tank body 2. The central axis of the tank body 2 is parallel to the ground. The support can be of any shape, as long as it can support the tank body 2, so that the tank body 2, the temporary storage unit 1, and the buffer unit 4 are suspended relative to the ground.

[0033] This type of thermal storage tank water distributor adopts a horizontal arrangement (i.e., the central axis inside the tank is parallel to the ground). Although the horizontal arrangement increases the overall footprint of the thermal storage tank, it significantly reduces the water pressure inside the tank 2 (especially at the bottom of the tank 2). Because the water pressure inside the tank 2 is significantly reduced, the sealing strength requirements for the entire tank 2 are also significantly reduced, and the probability of leakage is also greatly reduced. Since the water pressure on the tank 2 is significantly reduced, the probability of the entire tank 2 bursting is also greatly reduced. Furthermore, because the water pressure inside the tank 2 is relatively low due to the horizontal arrangement (compared to a vertical arrangement), even if the tank 2 bursts, the distance the water splashes out is relatively short, and the required pump head is also significantly reduced.

[0034] In summary, the horizontal arrangement of the water distributor in this heat storage tank reduces the water pressure inside the tank 2, thereby reducing the probability of the tank 2 bursting.

[0035] When the water distributor of the heat storage tank is in use, high-temperature water enters the tank 2 through the first opening 201 and exits the tank 2 through the first opening 201, while low-temperature water enters the tank 2 through the second opening 202 and exits the tank 2 through the second opening 202.

[0036] As attached Figure 1 and appendix Figure 3 As shown, it also includes a partition 6, which is disposed inside the tank 2. There are multiple partitions 6, and through holes are provided on the partitions 6. The partitions 6 divide the internal space of the tank 2 into multiple independent and interconnected water storage chambers. Each water storage chamber is provided with a first opening 201 and a second opening 202.

[0037] See appendix Figure 6 As shown in the diagram, in this solution, a baffle 6 is installed inside the tank 2. The baffle 6 is a circular plate made of metal, and the tank 2 is also made of metal. The baffle 6 is attached tightly to the inner wall of the tank 2, dividing the space inside the tank 2 into several independent and interconnected water storage chambers. Water in two adjacent water storage chambers can flow through the through holes on the baffle 6 to facilitate water exchange. Figure 6 As shown in the example, suppose that when a burst occurs somewhere on the right side of tank 2, and the burst point is located in a water storage chamber, the water in tank 2 will not flow out from the burst opening all at once due to the separation and water blocking effect of the baffle 6. This slows down the speed at which water flows out of tank 2, and the water level in several water storage chambers decreases gradually from left to right, which can provide more escape time for on-site personnel. At the same time, the water flowing through the through holes on the baffle 6 can generate a large noise, thus serving as an alarm.

[0038] As attached Figure 1 and appendix Figure 3As shown, it also includes a sleeve rod 5, a partition plate 6 that slides together with the inner wall of the tank body 2, the sleeve rod 5 is set inside the tank body 2 and the sleeve rod 5 is parallel to the central axis of the tank body 2, the partition plate 6 is slidably sleeved on the sleeve rod 5 through its own through hole, a limit ring 11 is fixedly set on the sleeve rod 5, and limit rings 11 are set on both sides of the partition plate 6, and the sleeve rod 5 is parallel to the central axis of the tank body 2.

[0039] See appendix Figure 3 Appendix Figure 4 and appendix Figure 6 As shown, the two ends of the sleeve 5 are fixed to the two planar end faces of the tank 2. The sleeve 5 is parallel to the central axis of the tank 2, while the baffle 6 is perpendicular to the central axis of the tank 2. Limiting rings 11 are provided on both sides of the baffle 6. The baffle 6 can slide between the two limiting rings 11. In this way, when the tank 2 bursts and water flows out of the tank 2, the water flow formed inside the tank 2 may cause the baffle 6 to move inside the tank 2 and rub against the inner wall of the tank 2. The inner wall of the tank 2 may generate a low-frequency noise similar to a buzzing sound during the friction of the baffle 6. This can serve as a warning to the on-site workers. At the same time, the slidability of the baffle 6 can also slow down the speed of water outflow to a certain extent.

[0040] As attached Figure 1 and appendix Figure 3 As shown, it also includes a buffer 4 and a temporary storage 1. The second opening 202 of the tank 2 is connected to the buffer 4, and the first opening 201 of the tank 2 is connected to the temporary storage 1.

[0041] Specifically, water enters and exits between the tank 2 and the buffer 4 through the second opening 202, and enters and exits between the tank 2 and the temporary storage unit 1 through the first opening 201. The function of both the buffer 4 and the temporary storage unit 1 is to smooth the water flow and ensure that the water flows into and out of the tank 2 with as little vibration as possible.

[0042] As attached Figure 1 Appendix Figure 2 and appendix Figure 5 As shown, it also includes a slide rod 7, a first stop block, and a second stop block 10. The temporary storage device 1 has an exhaust hole, which is a frustum-shaped exhaust hole. The wide opening of the exhaust hole is located inside the temporary storage device 1, and the narrow opening of the exhaust hole is located outside the temporary storage device 1. The slide rod 7 is a frustum-shaped slide rod 7, which slides together with the exhaust hole. The first stop block and the second stop block 10 are both set on the slide rod 7. The first stop block is located inside the temporary storage device 1, and the second stop block 10 is located outside the temporary storage device 1. A sealing ring 9 is set on the inner wall of the temporary storage device 1. The sealing ring 9 is used to contact the first stop block. The density of the slide rod 7, the density of the first stop block, and the density of the second stop block 10 are all less than that of water.

[0043] Specifically, the slide bar 7, the first stop, and the second stop 10 are all made of polypropylene plastic (the hot melt temperature of polypropylene is around 150℃, and the water temperature inside the tank 2 does not exceed 80℃). The first stop, the second stop 10, and the slide bar 7 are located at the top of the temporary storage unit 1, which is located above the tank 2. The buffer 4 is located below the tank 2. In this structure, when the water in the temporary storage unit 1 contains air bubbles, the bubbles surge back towards the vent. At this time, since the water is no longer in contact with the slide bar 7 and the first stop, under its own gravity, the first stop, carrying the slide bar 7, falls down, and the air bubbles escape from the vent. Then, the water level rises again, causing the slide bar 7 to float up. The slide bar 7 then presses against the vent again and seals the vent. The sealing ring 9 is set on the inner wall of the temporary storage unit 1 to further improve the sealing performance. Figure 5 The middle arrow points in the direction of the buoyancy of the water. When there are no air bubbles in the water, the water can block the vent hole and prevent leakage by relying on its own buoyancy. The greater the water pressure, the better the sealing performance.

[0044] As attached Figure 1 and appendix Figure 3 As shown, the buffer 4 has a buffer inlet / outlet 401, and the temporary storage 1 has a temporary storage inlet / outlet 101. Both the buffer inlet / outlet and the temporary storage inlet / outlet 101 are connected to transparent tubes, and a ring-shaped light strip 12 is sleeved on the transparent tubes.

[0045] Because the water entering tank 2 (including temporary storage 1 and buffer 4) may come from municipal tap water, which contains hypochlorous acid, a highly corrosive acid (extremely corrosive to various rubber sealing elements), transparent pipes are connected to the buffer inlet / outlet and the temporary storage inlet / outlet 101. Water flows through these transparent pipes, and a ring-shaped light strip 12 fitted onto the transparent pipes emits ultraviolet light to irradiate the water, causing the hypochlorous acid to degrade into hydrogen chloride, which is relatively more corrosive. The small amount of oxygen produced during the degradation process is eventually discharged through the vent.

[0046] As attached Figure 1 and appendix Figure 3 As shown, it also includes a temperature measuring rod 3, which is equipped with multiple water temperature sensors. The two adjacent water temperature sensors on the temperature measuring rod 3 do not contact each other. The temperature measuring rod 3 is set on the tank body 2, and all the water temperature sensors on the temperature measuring rod 3 are located inside the tank body 2.

[0047] Multiple water temperature sensors are set on each temperature measuring rod 3. The temperature measuring rod 3 is set on the tank 2, and the water temperature sensors are located inside the tank 2. This allows for temperature detection in various corners inside the tank 2.

[0048] As attached Figure 1 and appendix Figure 3 As shown, a pressure probe is installed on tank 2.

[0049] There are multiple pressure probes, and each water storage chamber has a pressure probe. The function of the pressure probe is to detect the water pressure inside the tank 2.

[0050] To maintain heat, the outer surfaces of the tank, temporary storage container, and buffer are all covered with polyurethane insulation, and thin steel plates are used to cover the polyurethane insulation.

[0051] The above description is merely a preferred embodiment of the present invention and does not limit the scope of patent protection of the present invention. Any equivalent modifications made based on the content of the present invention specification, whether directly or indirectly applied to other related technical fields, are similarly included within the scope of protection of the present invention.
