Description

Technical Field

[0001] The embodiments of this application relate to the field of cooling devices for pressure vessels, and particularly to an oxygen control device, a lead-bismuth reactor, and a method for adjusting the oxygen content of the lead-bismuth alloy in the reactor. Background Technology

[0002] The statements herein are provided merely as background information in connection with this application and do not necessarily constitute prior art.

[0003] Liquid metals such as lead or bismuth-lead are excellent nuclear fuel coolants, but they are extremely corrosive to reactor structural materials. Under oxygen-deficient conditions, liquid lead or bismuth-lead will dissolve and react with the alloy components of the reactor's structural materials, causing damage to the reactor's cooling system piping and equipment. Conversely, if the oxygen content is too high, the dissolved oxygen will react with some elements in the reactor structural materials to form solid oxides. These oxides deposit in the coolant circuit, causing blockages in the reactor's piping. Therefore, it is necessary to control the oxygen content in liquid lead or bismuth-lead to ensure the safe and stable operation of the cooling circuit and the reactor. Summary of the Invention

[0016] The following disclosure provides several different implementations or examples for carrying out this application. To simplify the disclosure of this application, specific examples of components and methods are described below. Of course, these are merely examples and are not intended to limit this application.

[0017] When lead or lead-bismuth is used as a coolant, it is typically in a high-temperature or ultra-high-temperature environment. The high-temperature environment inside the reactor significantly affects its oxygen content. High temperatures alter the oxygen solubility balance, accelerate oxygen-related mass exchange and reaction processes, and affect the stability of the cooling system. Therefore, it is necessary to precisely maintain the oxygen concentration of the lead or lead-bismuth alloy in the cooling system within a preset range.

[0018] To address the aforementioned problems, embodiments of this application provide an oxygen control device suitable for controlling the oxygen content of lead-bismuth alloys within containers in high-temperature environments. Figure 1 This is a schematic diagram of the oxygen control device provided in the embodiments of this application, as shown below. Figure 1As shown, the oxygen control device 100 includes: a measuring element 1, configured to measure the oxygen content of the lead-bismuth alloy in the container 5 under high temperature conditions; an oxygen removal mass exchanger 2, configured to reduce the oxygen content in the lead-bismuth alloy in the container 5; an oxygen release mass exchanger 3, configured to increase the oxygen content in the lead-bismuth alloy in the container 5; and a control component 4, configured to adjust the oxygen content of the lead-bismuth alloy by increasing or decreasing it using the oxygen removal mass exchanger 2 or the oxygen release mass exchanger 3 based on the measurement result of the lead-bismuth alloy by the measuring element 1, and the adjustment is performed in the sealed space between the container 5, the oxygen removal mass exchanger 2, and the oxygen release mass exchanger 3.

[0019] The oxygen control device 100 provided in the embodiments of this application measures and obtains the oxygen content data of the lead-bismuth alloy in the container 5 in real time by setting a measuring element 1 and a control component 4. Then, it uses an oxygen deoxygenating mass exchanger 2 and an oxygen releasing mass exchanger 3 to adjust the oxygen content level in the container 5 in real time, thereby accurately maintaining the oxygen concentration in the lead-bismuth alloy within a preset range to ensure the stable operation of the cooling system. By setting the container 5, the oxygen deoxygenating mass exchanger 2 and the oxygen releasing mass exchanger 3 into a closed space, the oxygen content adjustment process of the lead-bismuth alloy is realized in a closed environment, avoiding the introduction of impurities and ensuring the quality of the lead-bismuth alloy.

[0020] In some embodiments, container 5 is fluidly connected to deoxygenating mass exchanger 2 and oxygen-releasing mass exchanger 3, so that the lead-bismuth alloy in container 5 can enter and exit deoxygenating mass exchanger 2 into container 5, and enter and exit oxygen-releasing mass exchanger 3 into container 5. This allows for the supply or absorption of oxygen to the lead-bismuth alloy while isolating it from the external environment, thereby controlling the oxygen content in the lead-bismuth alloy.

[0021] In some embodiments, such as Figure 1 As shown, the deoxygenating mass exchanger 2 is provided with a deoxygenating medium 21, and the oxygen releasing mass exchanger 3 is provided with an oxygen releasing component 31. The deoxygenating medium 21 and the oxygen releasing component 31 can both be set at the same height above the lead-bismuth alloy liquid surface, so that the lead-bismuth alloy does not come into contact with the deoxygenating medium 21 and the oxygen releasing component 31 at the initial liquid level, which is beneficial for the measuring device 1 to obtain accurate oxygen content data in the initial state.

[0022] In some embodiments, the deoxygenating mass exchanger 2 and the oxygen releasing mass exchanger 3 can be configured to be partially immersed in the lead-bismuth alloy. For example, both the deoxygenating mass exchanger 2 and the oxygen releasing mass exchanger 3 can be configured as tubular structures with open bottoms, so that the lead-bismuth alloy can flow into the deoxygenating mass exchanger 2 or the oxygen releasing mass exchanger 3, and then contact the deoxygenating medium 21 or the oxygen releasing component 31 to achieve oxygen mass exchange, and can flow back into the container 5.

[0023] In some embodiments, the control component 4 includes a control element 41 and a power element 42. The control element 41 is configured to control the power element 42, and is configured to, based on the measurement results of the lead-bismuth alloy by the measuring element 1, cause the power element 42 to cause the lead-bismuth alloy in the container 5 to enter the deoxygenating mass exchanger 2 or the releasing oxygen mass exchanger 3 to adjust the oxygen content of the lead-bismuth alloy, thereby increasing or decreasing it. This enables automatic adjustment of the oxygen content based on the real-time oxygen content data obtained by the measuring element 1.

[0024] In some embodiments, the measuring element 1 is configured to extend into the lead-bismuth alloy in the initial liquid level state so that when the lead-bismuth alloy is regulated to flow in the deoxygenating mass exchanger 2 or the releasing oxygen mass exchanger 3, the measuring element 1 can always be in contact with the lead-bismuth alloy to measure and obtain oxygen content data.

[0025] In some embodiments, the measuring element 1 is configured to feed back the measured oxygen content data to the control element 41 in real time, which helps to adjust the oxygen content of the lead-bismuth alloy in a timely manner.

[0026] In some embodiments, the power unit 42 includes a first circuit 421, a second circuit 422, a power source 423, an air pipeline 424, and multiple switching valves. The power source 423 and the air pipeline 424 are configured such that the power source 423 changes the air pressure of the container 5 using the air pipeline 424. The power source 423 and the first circuit 421 are configured such that the power source 423 can change the gas content of the deoxygenation mass exchanger 2 using the first circuit 421. The power source 423 and the second circuit 422 are configured such that the power source 423 can change the gas content of the oxygen release mass exchanger 3 using the second circuit 422. By changing the air pressure of the container 5, the lead-bismuth alloy inside the container 5 can be forced into the deoxygenation mass exchanger 2 or the oxygen release mass exchanger 3 by the air pressure. This control method simplifies the drive settings for the lead-bismuth alloy.

[0027] In some embodiments, such as Figure 1 As shown, the first circuit 421, the second circuit 422, and the air pipe 424 are all configured to be connected to the power source 423, and each of the first circuit 421, the second circuit 422, and the air pipe 424 is equipped with a switch valve so that the power source 423 can control them separately.

[0028] In some embodiments, the first circuit 421 is configured to be connected to the deoxygenating mass exchanger 2, and the second circuit 422 is configured to be connected to the oxygen-releasing mass exchanger 3. Since both the deoxygenating mass exchanger 2 and the oxygen-releasing mass exchanger 3 are partially immersed in the lead-bismuth alloy and their interiors are both set to a gas-sealed environment, the power source 423 can control the pressure inside the deoxygenating mass exchanger 2 and the oxygen-releasing mass exchanger 3 through the first circuit 421 and the second circuit 422 respectively, so as to control the liquid level position of the lead-bismuth alloy in the deoxygenating mass exchanger 2 and the oxygen-releasing mass exchanger 3.

[0029] In some embodiments, such as Figure 1 As shown, the air line 424 can be configured to be connected to the first circuit 421 and the second circuit 422 respectively, so as to control the gas in the container 5 to enter or leave the deoxygenation mass exchanger 2 or the oxygen release mass exchanger 3 respectively, so as to control the position of the lead-bismuth alloy liquid surface in the deoxygenation mass exchanger 2 or the oxygen release mass exchanger 3 respectively.

[0030] In some embodiments, the deoxygenation mass exchanger 2 is equipped with a first level gauge 22, which is communicatively connected to the control component 4. The first level gauge 22 is configured to provide a signal to the control component 4 when the lead-bismuth alloy level in the deoxygenation mass exchanger 2 reaches a predetermined value, so that the control component 4 controls the lead-bismuth alloy to stop entering the deoxygenation mass exchanger 2. Setting a predetermined level value in the deoxygenation mass exchanger 2, so that the control component 4 stops controlling the rise of the lead-bismuth alloy level according to the feedback signal from the first level gauge 22, can stabilize the liquid level in the deoxygenation mass exchanger 2, which helps to stably remove oxygen from the lead-bismuth alloy therein.

[0031] In some embodiments, the oxygen-releasing mass exchanger 3 is equipped with a second level gauge 32, which is communicatively connected to the control component 4. The second level gauge 32 is configured to provide a signal to the control component 4 when the lead-bismuth alloy level in the oxygen-releasing mass exchanger 3 reaches a predetermined value, so that the control component 4 controls the lead-bismuth alloy to stop entering the oxygen-releasing mass exchanger 3. Setting a predetermined level value in the oxygen-releasing mass exchanger 3, so that the control component 4 stops controlling the rise of the lead-bismuth alloy level based on the feedback signal from the second level gauge 32, can stabilize the liquid level in the oxygen-releasing mass exchanger 3, which helps to stably release oxygen into the lead-bismuth alloy therein.

[0032] In some embodiments, the first level gauge 22 and the second level gauge 32 are respectively arranged to extend in the deoxygenation mass exchanger 2 and the oxygen release mass exchanger 3, and are both located at the same height above the deoxygenation medium 21 and the oxygen release component 31. When the lead-bismuth alloy liquid surface in the deoxygenation mass exchanger 2 or the oxygen release mass exchanger 3 comes into contact with the first level gauge 22 or the second level gauge 32, the first level gauge 22 and the second level gauge 32 feed back a signal to the control unit 41, so that the control unit 41 controls the power source 423 to stop providing pressure to the first circuit 421 or the second circuit 422, so as to stabilize the liquid surface and facilitate the full realization of oxygen mass exchange.

[0033] In some embodiments, such as Figure 1 As shown, the control component 4 includes multiple switching valves, including a first switching valve 4201, a second switching valve 4202, a third switching valve 4203, and a fourth switching valve 4204.

[0034] The following is a specific operation process of the oxygen control device 100 provided in this application.

[0035] In the initial state, the deoxygenating mass exchanger 2 and the oxygen releasing mass exchanger 3 are set to the same pressure as the container 5, and multiple switching valves are set to the closed state to make the initial liquid level of lead-bismuth alloy in the container 5 stable.

[0036] The target value of oxygen content in the container is determined. When the oxygen content in the lead-bismuth alloy measured by measuring element 1 is lower than the target value, the second switch valve 4202 set in the second circuit 422 is opened. The power source 423 transfers the gas in the oxygen release mass exchanger 3 to the container 5, thereby creating a pressure difference between the container 5 and the oxygen release mass exchanger 3, so that the liquid level of the lead-bismuth alloy in the oxygen release mass exchanger 3 rises to contact the oxygen release component 31. When the liquid level of the lead-bismuth alloy rises to the position set by the second level gauge 32, the power source 423 stops running and the second switch valve 4202 closes. At this time, the lead-bismuth alloy absorbs the oxygen in the oxygen release component 31.

[0037] When the oxygen content in the lead-bismuth alloy measured by measuring device 1 reaches the target value, the third switch valve 4203, which is located between the second circuit 422 and the air pipeline 424, is opened to make the pressure in container 5 and oxygen release mass exchanger 3 the same. The lead-bismuth alloy falls back into container 5 as the pressure difference disappears, so as to disconnect from the oxygen release component 31. After a predetermined time, the third switch valve 4203 is closed.

[0038] When the oxygen content in the lead-bismuth alloy measured by measuring device 1 is higher than the target value, the first switch valve 4201 set in the first circuit 421 is opened, and the power source 423 transfers the gas in the deoxygenation mass exchanger 2 to the container 5, thereby creating a pressure difference between the container 5 and the deoxygenation mass exchanger 2, so that the liquid level of the lead-bismuth alloy in the deoxygenation mass exchanger 2 rises to contact with the deoxygenation medium 21. When the liquid level of the lead-bismuth alloy rises to the position set by the first level gauge 22, the power source 423 stops running and the first switch valve 4201 closes. At this time, the deoxygenation medium 21 absorbs the oxygen in the lead-bismuth alloy that is in contact with it.

[0039] When the oxygen content in the lead-bismuth alloy measured by measuring device 1 reaches the target value, the fourth switch valve 4204, which is located between the first circuit 421 and the air pipeline 424, is opened to make the pressure in container 5 and deoxygenation mass exchanger 2 the same. The lead-bismuth alloy falls back into container 5 as the pressure difference disappears, so as to disconnect from the deoxygenation medium 21. After a predetermined time, the fourth switch valve 4204 is closed.

[0040] In some embodiments, if the power source 423 has a self-sealing capability when shutting down, there is no need to install the first switching valve 4201 and the second switching valve 4202 on the first circuit 421 and the second circuit 422, so as to simplify the control operation.

[0041] Another embodiment of this application provides a lead-bismuth reactor, which includes: a reactor body; and the aforementioned oxygen control device, which is disposed in the reactor body and configured to adjust the oxygen content of the lead-bismuth alloy within the reactor body.

[0042] The lead-bismuth reactor provided in the embodiments of this application, by setting the aforementioned oxygen control device 100 in the reactor body, can actively adjust the oxygen content in the lead-bismuth alloy and maintain the oxygen content at a reasonable concentration, which can effectively inhibit the corrosion of reactor structural materials and reduce the deposition of solid oxides, thus achieving long-term stable operation of the reactor.

[0043] Another aspect of the embodiments of this application provides a method for adjusting the oxygen content of a lead-bismuth alloy in a reactor, the method employing the aforementioned oxygen control device.

[0044] The method for adjusting the oxygen content of lead-bismuth alloy in a reactor provided in the embodiments of this application, by employing the aforementioned oxygen control device 100, can adjust the oxygen content level in the container in a high-temperature environment in real time, thereby accurately maintaining the oxygen concentration in the lead-bismuth alloy within a preset range to ensure the stable operation of the cooling system.

[0045] In some embodiments, the method for adjusting the oxygen content of lead-bismuth alloy in a reactor provided by the embodiments of this application includes the following steps: S1: determining the oxygen content of lead-bismuth alloy in the reactor using measuring device 1; S2: determining, based on the oxygen content of lead-bismuth alloy determined in step S1, whether to allow lead-bismuth alloy in the reactor to enter either deoxygenation mass exchanger 2 or oxygen release mass exchanger 3; S3: determining the oxygen content of lead-bismuth alloy in the reactor again; S4: determining, based on the oxygen content of lead-bismuth alloy determined in step S3, whether to stop allowing lead-bismuth alloy to enter either deoxygenation mass exchanger 2 or oxygen release mass exchanger 3, and returning the lead-bismuth alloy that has already entered either deoxygenation mass exchanger 2 or oxygen release mass exchanger 3 to the reactor. Based on the oxygen content of the lead-bismuth alloy in the reactor obtained from the measuring device 1, the lead-bismuth alloy is controlled to enter one of the deoxygenation mass exchanger 2 or the oxygen release mass exchanger 3 for oxygen mass exchange. During the oxygen mass exchange process, the oxygen content of the lead-bismuth alloy is determined to stop the lead-bismuth alloy from entering the deoxygenation mass exchanger 2 or the oxygen release mass exchanger 3. This enables real-time monitoring of the oxygen content of the lead-bismuth alloy in the container 5 during the oxygen mass exchange process, so that the oxygen content is controlled within a precise range.

[0046] In some embodiments, in step S2, the amount of lead-bismuth alloy entering either the deoxygenating mass exchanger 2 or the releasing oxygen mass exchanger 3 is determined, and based on the amount, the amount of lead-bismuth alloy entering either the deoxygenating mass exchanger 2 or the releasing oxygen mass exchanger 3 is stopped. This allows for precise control of the amount of lead-bismuth alloy used for oxygen mass exchange, ensuring that the oxygen absorbed or released is controlled within a target range.

[0047] Regarding the embodiments of this application, it should also be noted that, without conflict, the embodiments of this application and the features in the embodiments can be combined with each other to obtain new embodiments.
