Description

A steam accumulator with a self-driven fan-blade gas distribution structure

[0001] This application claims priority to Chinese Patent Application No. 202410933402.0, filed on July 12, 2024, entitled "A Steam Regenerator with a Self-Driven Fan-Shaped Gas Distribution Structure", the entire contents of which are incorporated herein by reference. Technical Field

[0002] This invention relates to the field of heat accumulator technology, and more specifically, to a steam heat accumulator with a self-driven fan-shaped gas distribution structure. Background Technology

[0003] Steam accumulators have numerous applications in industrial production, commercial buildings, long-distance heating, and renewable energy. In industries such as chemicals, food processing, and textiles, steam accumulators stabilize steam supply and balance steam demand during peak and off-peak periods. They also recover waste heat generated during production, reducing energy consumption and costs. In large buildings such as commercial buildings and shopping malls, steam accumulators are used in heating and air conditioning systems to provide a stable source of heat. They also provide 24 / 7 hot water service, improving energy efficiency. In solar thermal power generation systems, steam accumulators store heat collected during the day and release it at night or on cloudy days, ensuring a continuous power supply. When integrated with wind power systems, excess wind power is used to produce and store steam for use when wind power is insufficient. In urban district heating systems, steam accumulators store heat and release it during peak periods to ensure the heating needs of residents and businesses.

[0004] Its advantage lies in the high energy density of steam, meaning that steam accumulators can store a large amount of thermal energy within a relatively small volume. Steam accumulators can quickly respond to changes in thermal demand, providing immediate thermal energy supply, making them suitable for applications requiring rapid adjustment. Pressure regulation can maintain steam at a relatively constant temperature during storage and release, ensuring the stability of thermal output.

[0005] Existing spherical steam accumulators cannot effectively disperse the concentrated high temperature brought in during air intake, thus failing to distribute heat evenly. Concentrated high temperature may lead to localized heat loss and unstable pressure during air intake and exhaust. At the same time, a fixed air intake on the same plane may cause pressure imbalance during air intake, thus requiring strict control of air intake conditions and extremely stringent pressure control within the tank.

[0006] Therefore, how to solve the problems of heat loss and pressure imbalance caused by concentrated high temperature during air intake is a problem that urgently needs to be solved by those skilled in the art. Summary of the Invention

[0007] In view of this, the purpose of this invention is to provide a steam accumulator with a self-driven fan-shaped gas distribution structure. The gas distribution mechanism rotates due to the force generated by the steam itself, and the high-temperature steam is evenly distributed to various parts of the accumulator body, making the heat input more uniform and reducing heat loss caused by local high temperature differences. The steam is discharged from different layers and different points in the accumulator body, which evens out the pressure distribution when the steam enters the accumulator body, and reduces the pressure on the accumulator body when the steam is distributed in the same layer. This reduces the requirements for the pressure control system of the accumulator body and increases the safety of the system.

[0008] To achieve the above objectives, the present invention provides the following technical solution:

[0009] A steam accumulator with a self-driven fan-shaped gas distribution structure includes: an accumulator body, a steam inlet pipe for introducing steam inside the accumulator body, a gas distribution mechanism arranged axially on the steam inlet pipe, the gas distribution mechanism being rotatably connected to the steam inlet pipe, an inner steam channel communicating with the steam inlet pipe in the inner cavity of the gas distribution mechanism, and a steam outlet hole communicating with the inner steam channel on the gas distribution mechanism. Steam discharged from the steam outlet hole is used to drive the rotation of the gas distribution mechanism.

[0010] Preferably, the gas distribution mechanism includes three fan-shaped blade structures, which are arranged circumferentially on the rotating sleeve. The rotating sleeve is nested in the steam inlet pipe and rotatably connected to the steam inlet pipe. The three blade structures are arranged along the axial direction of the rotating sleeve.

[0011] Preferably, the steam outlet hole is located on one side of the blade structure, and the steam outlet holes of all three blade structures are located on the same side, so that the steam discharged from the steam outlet hole drives the blade structure to rotate.

[0012] Preferably, the blade structure is provided with a fixing groove for installing a counterweight.

[0013] Preferably, at least two sets of steam outlet holes are provided, and at least two sets of steam outlet holes are evenly distributed on the blade structure.

[0014] Preferably, any group of steam outlet holes includes multiple circular holes, the ratio of the distance between two adjacent circular holes to the radius of the circular hole is 1:4 to 1:3, and the ratio of the distance between any two groups of steam outlet holes to the radius of the circular holes is 8:1 to 7:1.

[0015] Preferably, the heat accumulator body is equipped with an exhaust pipe, and a steam-water separator is installed on the exhaust pipe.

[0016] Preferably, the heat accumulator body is also provided with a steam preheating pipe, which has multiple steam preheating outlets. The steam preheating pipe is controlled to open and close by a preheating steam inlet valve, and the steam inlet pipe is controlled to open and close by a steam inlet valve. Both the preheating steam inlet valve and the steam inlet valve are connected to the controller.

[0017] Preferably, the bottom of the heat accumulator body is provided with a drain pipe and a drain valve for controlling the opening and closing of the drain pipe, and also with a water supply pipe and a water supply valve for controlling the opening and closing of the water supply pipe. Both the drain valve and the water supply valve are connected to the controller.

[0018] Preferably, the heat accumulator body is also equipped with a pressure gauge and a temperature detector connected to the controller.

[0019] The steam accumulator with a self-driven fan-shaped gas distribution structure provided by this invention includes an accumulator body. A steam inlet pipe is provided within the accumulator body for introducing steam. Steam is smoothly introduced into the accumulator body through the steam inlet pipe. A gas distribution mechanism is provided on the steam inlet pipe along its axial direction, allowing steam to enter different layers of the accumulator body's internal cavity. This effectively disperses the steam entering the accumulator body, preventing concentrated high temperatures that could lead to heat loss. The gas distribution mechanism is rotatably connected to the steam inlet pipe. The inner cavity of the gas distribution mechanism has a steam inner channel communicating with the steam inlet pipe. The gas distribution mechanism has a steam outlet hole communicating with the steam inner channel. Steam discharged from the steam outlet hole drives the gas distribution mechanism to rotate. The force generated by the steam itself causes the gas distribution mechanism to rotate, evenly distributing the high-temperature steam to various parts within the accumulator body. This makes the heat input more uniform, reduces heat loss caused by localized high-temperature differences, and reduces the pressure on the accumulator body during steam input. Furthermore, the steam is more dispersed, preventing pressure imbalances. Attached Figure Description

Detailed Implementation

[0027] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0028] In this invention, unless otherwise explicitly specified and limited, the terms "installation," "connection," "linking," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0029] The core of this invention is to provide a steam accumulator with a self-driven fan-shaped gas distribution structure. The gas distribution mechanism 3 rotates due to the force generated by the steam itself, and the high-temperature steam is evenly distributed to various parts of the accumulator body 1, making the heat input more uniform and reducing heat loss caused by local high temperature differences. The steam is discharged from different layers and different points in the accumulator body 1, which evens out the pressure distribution when the steam enters the accumulator body 1, and reduces the pressure on the accumulator body 1 when the steam is distributed in the same layer. This reduces the requirements for the pressure control system of the accumulator body 1 and increases the safety of the system.

[0030] Please refer to Figures 1 and 2. A steam accumulator with a self-driven fan-shaped gas distribution structure includes an accumulator body 1. Specifically, the accumulator body 1 is provided with a steam inlet pipe 2 for introducing steam. Steam is smoothly introduced into the accumulator body 1 through the steam inlet pipe 2. A gas distribution mechanism 3 is provided on the steam inlet pipe 2 along its axial direction, so that steam can be introduced into different layers of the inner cavity of the accumulator body 1, effectively dispersing the steam entering the accumulator body 1 and avoiding heat loss due to concentrated high temperature. The gas distribution mechanism 3 is rotatably connected to the steam inlet pipe 2. The inner cavity of the gas distribution mechanism 3 is provided with a steam inner channel 31 that communicates with the steam inlet pipe 2. The gas distribution mechanism 3 is provided with a steam outlet hole 32 that communicates with the steam inner channel 31. The steam discharged from the steam outlet hole 32 is used to drive the gas distribution mechanism 3 to rotate. The gas distribution mechanism 3 rotates due to the force brought by the steam itself, and the high-temperature steam is evenly distributed to various parts of the heat storage body 1, so that the heat input is more uniform, the heat loss caused by local high temperature difference is reduced, the pressure inside the heat storage body 1 is reduced when steam is input, and it is more dispersed to avoid the problem of pressure imbalance.

[0031] The heat accumulator body 1 is fixed by an outer support 16, and the steam inlet pipe 2 is fixed inside the heat accumulator body 1 by an inner support 17. The heat accumulator body has a spherical structure.

[0032] The steam accumulator with a self-driven fan-shaped gas distribution structure configured in the above manner uses the gas distribution mechanism 3 to drive the rotation of the gas distribution mechanism 3 by means of the kinetic energy of the high-temperature steam, thereby uniformly dispersing the high-temperature and high-pressure gas in the accumulator body 1, reducing heat loss and pressure imbalance caused by local high temperature.

[0033] In the above embodiment, the gas distribution mechanism 3 includes three fan-shaped blade structures 33. The blade structures 33 are arranged in the circumference of the rotating sleeve 4. The rotating sleeve 4 is nested in the steam inlet pipe 2 and is rotatably connected to the steam inlet pipe 2. The three blade structures 33 are arranged along the axial direction of the rotating sleeve 4.

[0034] It should be noted that the rotating sleeve 4 is provided with an air outlet that communicates with the steam inner channel 31. The high-temperature steam flowing through the steam entry pipe 2 enters the rotating sleeve 4, is discharged through the air outlet on the rotating sleeve 4 to the steam inner channel 31, and finally is discharged from the steam outlet hole 32 to the heat accumulator body 1.

[0035] Furthermore, the three fan-shaped blade structures 33 are installed in different layers of the rotating sleeve 4 at the lower end of the steam inlet pipe 2, without affecting each other. The fan-shaped design allows high-temperature and high-pressure steam to be evenly input into the heat accumulator body 1. The impact of the steam creates a force in one direction, causing the blade structure 33 to rotate, thereby driving the rotating sleeve 4 to rotate relative to the steam inlet pipe 2. This ensures the pressure balance of the heat accumulator body 1 and enables faster heat absorption, reducing heat loss caused by uneven temperature.

[0036] In this embodiment, the gas distribution mechanism 3 includes three fan-shaped blade structures 33, which are fixed at a fixed position on the rotating sleeve 4. The three blade structures 33 rotate synchronously. However, in practical applications, this is not a limitation, as long as the above-mentioned technical effect can be achieved.

[0037] Please refer to Figures 2, 3 and 4. The steam outlet hole 32 is located on one side of the blade structure 33. The steam outlet holes 32 of the three blade structures 33 are all located on the same side so that the steam discharged from the steam outlet hole 32 drives the blade structure 33 to rotate.

[0038] It is understandable that the steam outlet holes 32 of the three blade structures 33 are all located on the same side, so that steam can be discharged through the steam outlet holes 32 in the same direction of the blade structures 33, thereby pushing the blade structures 33 up, so that the steam entering the heat storage body 1 afterward changes with the steam entering the heat storage body 1, thereby making the heat storage more uniform and not in the same layer area, reducing the heat loss caused by the local high temperature difference caused by the steam entering the heat storage body 1.

[0039] In this embodiment, the steam is discharged from different layers and locations within the accumulator body 1, which evens out the pressure distribution during the intake of the accumulator body 1 and reduces the pressure on the accumulator body 1 when the steam is distributed in the same layer. This reduces the requirements for the pressure control system of the accumulator body 1 and increases the safety of the system.

[0040] Furthermore, the blade structure 33 is provided with a fixing groove for mounting the balance block 5.

[0041] It should be noted that the three fan-shaped blade structures 33 are installed on different layers of the rotating sleeve 4 at the lower end of the steam inlet pipe 2, and they do not affect each other. This is because the blade structure 33 is provided with a fixing groove for installing the balance block 5. By setting the balance block 5, the rotation balance of the blade structure 33 can be maintained, so there is no problem of rotational imbalance.

[0042] Please refer to Figure 5. At least two sets of steam outlet holes 32 are provided, and at least two sets of steam outlet holes 32 are evenly distributed on the blade structure 33.

[0043] Understandably, by setting multiple sets of steam outlet holes 32, the steam output is increased, thereby allowing the steam's impact force to overcome the gravity of the blade structure 33 and drive it to rotate. Furthermore, this allows the steam to enter the accumulator body 1 more dispersedly, avoiding the problem of localized high temperatures.

[0044] Based on the above embodiments, any group of steam outlet holes 32 includes multiple circular holes, the ratio of the distance between two adjacent circular holes to the radius of the circular hole is 1:4 to 1:3, and the ratio of the distance between any two groups of steam outlet holes 32 to the radius of the circular hole is 8:1 to 7:1.

[0045] It should be noted that each fan blade structure preferably has six groups of steam outlet holes 32, and each group preferably has 63 circular holes. The ratio of the radius of each circular hole to the spacing between the circular holes is preferably 4:1, and the ratio of the spacing between each group of steam outlet holes 32 to the radius of the circular holes is preferably 8:1, so as to make the steam output more efficient. However, in practical applications, there is no limitation on this, as long as the above technical effects can be achieved.

[0046] In the above embodiment, the heat accumulator body 1 is provided with an exhaust pipe 6, and a steam-water separator 7 is provided on the exhaust pipe 6.

[0047] Understandably, after the high-temperature and high-pressure steam enters through the steam inlet, it flows into the rotating sleeve 4 through the steam inlet pipe 2, enters the steam inner channel 31 of the blade structure 33 through the steam outlet hole of the rotating sleeve 4, and is discharged through the steam outlet hole 32, entering the heat accumulator body 1. When the steam is output, it is discharged through the exhaust pipe 6 and is processed by the steam-water separator 7 on the exhaust pipe 6 before being output to the next structure.

[0048] The high-temperature steam inside the heat accumulator body 1 can be extracted by an air pump or discharged from the heat accumulator body 1 by other means. There are no restrictions on this, as long as the above-mentioned technical effects can be achieved.

[0049] In a preferred embodiment, the heat storage body 1 is also provided with a steam preheating pipe 8, which has multiple steam preheating outlets 9. The steam preheating pipe 8 is controlled to open and close by a preheating steam inlet valve 10, and the steam inlet pipe 2 is controlled to open and close by a steam inlet valve 11. Both the preheating steam inlet valve 10 and the steam inlet valve 11 are connected to a controller.

[0050] It should be noted that before introducing high-temperature steam into the accumulator body 1, the controller opens the preheating steam inlet valve 10 to introduce preheating steam into the steam preheating pipe 8. The preheated steam flows through the steam preheating pipe 8 and enters the accumulator body 1 through the steam preheating outlet 9, thus avoiding significant heat loss due to the large temperature difference caused by directly introducing high-temperature steam. Then, the controller opens the steam inlet valve 11 to introduce high-temperature steam into the steam inlet pipe 2. The high-temperature steam flowing into the steam inlet pipe 2 passes through the rotating sleeve 4 and the blade structure 33, and finally enters the accumulator body 1 through the steam outlet hole 32.

[0051] In the above case, the bottom of the heat storage body 1 is provided with a drain pipe and a drain valve 12 for controlling the opening and closing of the drain pipe, and a water supply pipe and a water supply valve 13 for controlling the opening and closing of the water supply pipe. Both the drain valve 12 and the water supply valve 13 are connected to the controller.

[0052] Understandably, after preheated steam or high-temperature steam enters the heat accumulator body 1, a temperature difference is created between it and the heat accumulator body 1, causing condensation and the production of liquid. The liquid flows along the inner wall of the heat accumulator body 1 to the bottom. When the liquid level in the heat accumulator body 1 is too high, the casing controller controls the drain valve 12 to open, allowing the liquid in the heat accumulator body 1 to be discharged from the drain pipe. Before introducing preheated steam into the heat accumulator body 1, the controller controls the water supply valve 13 to open, allowing liquid to be introduced into the heat accumulator body 1 through the water supply pipe.

[0053] In the above embodiment, the heat storage body 1 is also provided with a pressure gauge 14 and a temperature detector 15 connected to the controller.

[0054] It should be noted that when the controller opens the preheating steam inlet valve 10 to introduce preheating steam into the accumulator body 1, the temperature inside the accumulator body 1 is monitored in real time by the temperature detector 15, and the detected data is sent to the controller in real time. The controller then controls the opening and closing times of the steam inlet valve 11 and the preheating steam inlet valve 10. The pressure gauge 14 monitors the steam pressure inside the accumulator body 1 in real time, and the monitoring result is sent to the controller in real time. The controller then controls the flow rate and pressure of the high-temperature steam entering the accumulator body 1.

[0055] The controller is not shown. The controller's data source is the pressure gauge 14 and multiple temperature detectors 15, thereby enabling intelligent control.

[0056] In summary, the steam accumulator with a self-driven fan-shaped gas distribution structure provided by this invention features a fan-shaped gas distribution mechanism 3. The high-temperature steam itself generates the force that causes the gas distribution mechanism 3 to rotate, distributing the high-temperature steam evenly to various parts within the accumulator body 1. This results in more uniform heat input, reduces heat loss due to localized high-temperature differences, and decreases the pressure within the accumulator body 1 when high-temperature steam is input. Furthermore, the pressure is more dispersed, requiring less external pressure control intervention. The maintenance cost of the gas distribution mechanism 3 is also lower, as maintenance can be achieved simply by replacing the gas distribution mechanism 3. This extends the overall service life and reduces maintenance difficulty and cost.
