[0001] The invention relates to the technical field of air-cooled micro-reactors, and in particular to an air-cooled micro-reactor main pipeline installation method and an air-cooled micro-reactor. Background Art
[0002] Gas-cooled micro reactors use gas (such as helium) as a coolant to remove the heat generated by the reactor through the flow of gas, achieving heat exchange and energy conversion. This cooling method has many advantages over traditional liquid coolants, such as higher energy efficiency, lower cost, smaller size and weight, and better reliability and stability.
[0003] In the related art, the gas-cooled micro reactor includes a reactor device, a main pipe and a power generation device. The main pipe includes an inner pipe and an outer pipe, and the outer pipe is sleeved on the outer side of the inner pipe. One end of the inner pipe is connected to the components in the reactor device, and the other end of the inner pipe is connected to the components in the power generation device. One end of the outer pipe is connected to the outer shell of the reactor device, and the other end of the outer pipe is connected to the outer shell of the power generation device.
[0004] The technical problem to be solved by the present invention is to provide a method capable of connecting an inner tube and an outer tube between a reactor device and a power generation device. Summary of the invention

[0006] In a first aspect, the present invention provides a method for installing a main pipeline of a gas-cooled micro reactor, comprising:
[0007] Connecting the inner pipe of the main pipeline to the structural components inside the power generation device;
[0008] Sleeve the outer tube of the main pipeline onto the outer side of the inner tube, and connect the outer tube to the shell of the power generation device;
[0009] Moving the power generation device, the inner tube and the outer tube as a whole, and inserting the inner tube into the core assembly inside the reactor device;
[0010] The outer tube is connected to the outer shell of the reactor device.
[0011] Beneficial effects: the inner tube is first connected to the structural assembly of the power generation device, the outer tube is connected to the shell of the power generation device, the inner tube is plugged into the core assembly of the reactor device, and the outer tube is connected to the outer shell of the reactor device, and finally the installation of the main pipeline between the reactor device and the power generation device is completed.
[0012] In addition, flange connections are used between the inner tube and the structural assembly, between the inner tube and the shell of the structural assembly, and between the outer tube and the outer shell of the reactor device. On the one hand, this can avoid the problem of welding deformation, and on the other hand, the gas-cooled micro-reactor can be disassembled and reassembled, providing convenience for the inspection and operation of the gas-cooled micro-reactor.
[0013] By connecting the inner tube to the core assembly of the reactivity device by plugging, the problem of being unable to connect and disassemble the inner tube and the core assembly due to the blocking and obstruction of the outer tube can be avoided.
[0014] In an optional embodiment, before the inner pipe of the main pipeline is connected to the structural component inside the power generation device, the method further includes:
[0015] The end cover of the power generation device is disassembled.
[0016] Beneficial effect: Before connecting the inner tube to the structural assembly, the end cover of the power generation device is disassembled to avoid the end cover from obstructing the inner tube and ensure that the inner tube can be installed smoothly. In addition, the end cover is provided and connected to the shell through a threaded fastener, which is convenient for processing a through hole matching the inner tube on the end cover and for processing a sealing groove and other structures on the through hole.
[0017] In an optional embodiment, the outer tube of the main pipeline is sleeved on the outer side of the inner tube, and the outer tube is connected to the shell of the power generation device, including:
[0018] Sleeve the end cover on the outer side of the inner tube, and connect the end cover to the shell;
[0019] Connect the outer tube to the end cap.
[0020] Beneficial effects: The outer tube can be connected to the shell of the power generation device through the end cover, so that the connection hole and other structures connected to the outer tube can be arranged on the end cover, and the docking surface with the outer tube can be processed on the end cover.
[0021] In an optional embodiment, before the outer tube of the main pipeline is sleeved on the outer side of the inner tube, the method further includes:
[0022] A portion of the inner tube located outside the housing is supported.
[0023] Beneficial effect: By supporting the inner tube, on the one hand, displacement or shaking of the inner tube can be avoided, and the relative position accuracy of the inner tube and the structural component can be ensured, so as to facilitate the connection of the inner tube and the structural component. On the other hand, deformation or damage of the connection between the inner tube and the structural component due to the deadweight of the inner tube can be avoided.
[0024] In an optional embodiment, the outer pipe of the main pipeline is sleeved on the outer side of the inner pipe, comprising:
[0025] The outer tube is sleeved on the outer side of the inner tube, and when the outer tube is close to the supporting position of the inner tube, the supporting position of the inner tube is changed to an end of the inner tube away from the power generation device and extending out of the outer tube.
[0026] Beneficial effect: In the process of sleeve the outer tube on the inner side of the inner tube, by changing the support position of the support tooling, it is possible to avoid the support tooling from causing obstruction and interference to the outer tube, and enable the support tooling to continue to provide support for the inner tube.
[0027] In an optional embodiment, after the outer tube is connected to the shell, the method further comprises:
[0028] The outer tube is supported.
[0029] Beneficial effect: By supporting the outer tube, deformation or damage of the connection between the outer tube and the shell of the power generation device due to the deadweight of the outer tube can be avoided.
[0030] In an optional embodiment, before the inner tube is plugged into the core assembly inside the reactor device, the process further includes:
[0031] Extending at least a portion of a fixing device between the inner tube and the outer tube so that the fixing device supports the inner tube and the outer tube;
[0032] After the inner tube enters the outer shell to a preset depth, the fixing device is removed.
[0033] Beneficial effect: By supporting the fixing device between the inner tube and the outer tube, the inner tube and the outer tube can be mutually limited in the radial direction. In this way, the inner tube support fixture can be removed, so that the outer tube and the inner tube can be supported together by the outer tube support fixture, avoiding interference between the inner tube support fixture and the reactor device during the plugging process of the inner tube and the core assembly.
[0034] In an optional embodiment, the fixing device includes two half-ring structures;
[0035] Accordingly, extending at least part of the fixing device between the inner tube and the outer tube comprises:
[0036] The two semi-ring structures are sleeved on the outer side of the inner tube, and the two semi-ring structures are connected by threaded fasteners to form an annular structure, so as to support the outer tube by the annular structure.
[0037] Beneficial effect: The two semi-ring structures are respectively buckled on both sides of the inner tube, and the two semi-ring structures are butted, and then the two semi-ring structures are connected by threaded fasteners to form an annular structure. The inner diameter of the annular structure is greater than or equal to the outer diameter of the inner tube, and the outer diameter of the annular structure is less than or equal to the inner diameter of the outer tube. By setting up two semi-ring structures, when it is necessary to remove the semi-ring structure from the inner tube, the threaded fasteners of the two semi-ring structures can be directly loosened to completely detach the two semi-ring structures, without removing the fixing device from the end of the inner tube, so that the fixing device can be removed when the inner tube extends into the interior of the reactor device.
[0038] In an optional embodiment, before connecting the outer tube to the shell of the reactor device, the method further includes:
[0039] The coaxiality of the outer tube and the inner tube, and the parallelism between the flange surface of the outer tube and the flange surface of the outer shell are detected, and when at least one of the coaxiality and the parallelism does not meet the preset value, the outer tube and the power generation device are adjusted.
[0040] Beneficial effect: When at least one of the coaxiality error and the parallelism error exceeds the precision requirement, the outer tube and the power generation device are adjusted, for example, the outer tube deflection angle can be adjusted, or the position or deflection angle of the power generation device can be adjusted, so that both the coaxiality and the parallelism meet the corresponding precision requirements, thereby ensuring the installation accuracy of the air-cooled micro-reactor. The position of the power generation device can be a height position or a horizontal position.
[0041] In a second aspect, the present invention further provides an air-cooled micro-reactor, which is installed based on the main pipeline installation method of the air-cooled micro-reactor as described above.

[0050] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present invention.
[0051] Combine the following Figures 1 to 4 , describing the air-cooled micro-reactor main pipeline installation method provided in an embodiment of the present invention.
[0052] Specifically, the gas-cooled micro-reactor main pipeline installation method is used to install the main pipeline 1 between the power generation device 2 and the reactor device 3, including steps S100 to S400.
[0053] Step S100 : connecting the inner pipe 101 of the main pipeline 1 to the structural component 201 inside the power generation device 2 .
[0054] Specifically, the structural component 201 inside the power generation device 2 includes but is not limited to a steam generator. The inner tube 101 is connected to the structural component 201 through a flange, that is, the flange of the inner tube 101 is butted against the flange surface of the structural component 201, and is connected through threaded fasteners. For example, a bolt tensioner can be used to complete the flange connection between the inner tube 101 and the structural component 201.
[0055] Step S200 , the outer tube 102 of the main pipeline 1 is mounted on the outer side of the inner tube 101 , and the outer tube 102 is connected to the shell 202 of the power generation device 2 .
[0056] Specifically, the outer tube 102 is mounted on the outer side of the inner tube 101 from the end of the inner tube 101 away from the structural assembly 201. The outer tube 102 is connected to the shell 202 through a flange, that is, the flange of the outer tube 102 is butted against the flange surface of the shell 202, and connected through threaded fasteners. For example, the flange connection between the outer tube 102 and the shell 202 can be completed by a bolt tensioner. Among them, the length of the inner tube 101 is greater than the length of the outer tube 102. The inner tube 101 is used to allow the high-temperature medium gas in the reactor device 3 to enter the power generation device 2, and the outer tube 102 is used to allow the low-temperature medium gas in the power generation device 2 to return to the reactor device 3. The structural assembly 201 is arranged in the chamber of the shell 202.
[0057] Step S300 , the power generation device 2 , the inner tube 101 and the outer tube 102 are moved as a whole, and the inner tube 101 is plugged into the core assembly 301 inside the reactor device 3 .
[0058] Specifically, the main pipeline 1 and the power generation device 2 can be hoisted onto a transport vehicle as a whole by means of a lifting device or other transport equipment. The power generation device, the inner tube 101 and the outer tube 102 are moved close to the reactor device 3 by means of the transport vehicle, and the inner tube 101 is plugged into the core assembly 301. For example, the inner tube 101 is plugged into and sealed with the core assembly 301 by means of a carbon ring compression structure.
[0059] Step S400 , connecting the outer tube 102 to the outer shell 302 of the reactor device 3 .
[0060] Specifically, the outer tube 102 is connected to the outer shell 302 through a flange, that is, the flange of the outer tube 102 is butted against the flange surface of the outer shell 302, and connected through threaded fasteners. For example, the flange connection between the outer tube 102 and the outer shell 302 can be completed by a bolt tensioner. The core assembly 301 is disposed in the chamber of the outer shell 302.
[0061] In this embodiment, the inner tube 101 is connected to the structural component 201 of the power generation device 2, the outer tube 102 is connected to the shell 202 of the power generation device 2, the inner tube 101 is plugged into the core assembly 301 of the reactor device 3, and the outer tube 102 is connected to the outer shell 302 of the reactor device 3, and finally the installation of the main pipeline 1 between the reactor device 3 and the power generation device 2 is completed.
[0062] In addition, flange connections are adopted between the inner tube 101 and the structural assembly 201, between the inner tube 101 and the shell 202 of the structural assembly 201, and between the outer tube 102 and the outer shell 302 of the reactor device 3. On the one hand, the problem of welding deformation can be avoided, and on the other hand, the gas-cooled micro-reactor can be disassembled and reassembled, which provides convenience for the inspection and maintenance of the gas-cooled micro-reactor.
[0063] By connecting the inner tube 101 and the core assembly 301 of the reactivity device by plugging, the problem of being unable to connect and disassemble the inner tube 101 and the core assembly 301 due to the blocking and obstruction of the outer tube 102 can be avoided.
[0064] In some embodiments provided by the present invention, before the inner pipe 101 of the main pipeline 1 is connected to the structural component 201 inside the power generation device 2, the following steps are also included:
[0065] Step S010: dismantle the end cover 203 of the power generation device 2.
[0066] Specifically, the end cover 203 of the power generation device 2 can be removed from the housing 202 manually or by a robot, and the end cover 203 can be hoisted by a hoisting device. For example, the end cover 203 is connected to the housing 202 by a threaded fastener. The end cover 203 can also be called a head.
[0067] In this embodiment, before the inner tube 101 is connected to the structural assembly 201, the end cover 203 of the power generation device 2 is disassembled, so as to avoid the end cover 203 from obstructing the inner tube 101 and ensure that the inner tube 101 can be installed smoothly. In addition, the end cover 203 is provided and connected to the housing 202 by threaded fasteners, so that a through hole matching the inner tube 101 can be machined on the end cover 203, and a sealing groove and other structures can be machined on the through hole.
[0068] In some embodiments provided by the present invention, the outer tube 102 of the main pipeline 1 is sleeved on the outer side of the inner tube 101, and the outer tube 102 is connected to the shell 202 of the power generation device 2, including:
[0069] S210 , sleeve the end cover 203 onto the outer side of the inner tube 101 , and connect the end cover 203 to the shell 202 .
[0070] Specifically, the end cover 203 is hoisted by a hoisting device, and the end cover 203 is sleeved on the outer side of the inner tube 101 from the end of the inner tube 101 away from the structural assembly 201. The end cover 203 is then butted and connected to the shell 202. For example, the end cover 203 and the shell 202 can be connected by a bolt tensioner.
[0071] S220 , connecting the outer tube 102 to the end cover 203 .
[0072] Specifically, the outer tube 102 is hoisted by a hoisting device, and the outer tube 102 is sleeved on the outer side of the inner tube 101. The flange of the outer tube 102 is then butted against the end cover 203 by the hoisting device, and then the flange of the outer tube 102 and the end cover 203 are connected by threaded fasteners. For example, the flange connection between the outer tube 102 and the end cover 203 can be completed by a bolt tensioner.
[0073] In this embodiment, the outer tube 102 can be connected to the shell 202 of the power generation device 2 through the end cover 203, so that a connection hole and other structures connected to the outer tube 102 can be set on the end cover 203, and a docking surface for docking with the outer tube 102 can be processed on the end cover 203.
[0074] In some embodiments provided by the present invention, before the outer pipe 102 of the main pipeline 1 is sleeved on the outer side of the inner pipe 101, the following steps are further included:
[0075] S110 , supporting the portion of the inner tube 101 located outside the shell 202 .
[0076] Specifically, after the end cover 203 is disassembled, the inner tube 101 can be hoisted by a hoisting device, and the inner tube 101 can be moved to the position of the structural assembly 201 by the hoisting device. Then, the inner tube 101 is supported by a supporting tool to prevent the inner tube 101 from sagging, thereby ensuring the relative position accuracy between the inner tube 101 and the structural assembly 201. Then, the inner tube 101 and the structural assembly 201 are flange-connected.
[0077] In this embodiment, by supporting the inner tube 101, on the one hand, displacement or shaking of the inner tube 101 can be avoided, and the relative position accuracy of the inner tube 101 and the structural assembly 201 can be ensured, so as to facilitate the connection of the inner tube 101 and the structural assembly 201. On the other hand, deformation or damage of the connection between the inner tube 101 and the structural assembly 201 due to the deadweight of the inner tube 101 can be avoided.
[0078] In some embodiments provided by the present invention, the outer pipe 102 of the main pipe 1 is sleeved on the outer side of the inner pipe 101, including:
[0079] S205 , the outer tube 102 is sleeved on the outer side of the inner tube 101 , and when the outer tube 102 is close to the supporting position of the inner tube 101 , the supporting position of the inner tube 101 is changed to an end of the inner tube 101 away from the power generation device 2 and extending out of the outer tube 102 .
[0080] Specifically, the outer tube 102 is sleeved onto the inner tube 101 from the end of the inner tube 101 away from the structural assembly 201, and the supporting fixture is removed when the outer tube 102 is close to the supporting fixture supporting the inner tube 101. Since the length of the outer tube 102 is shorter than the length of the inner tube 101, when the outer tube 102 is sleeved onto the inner tube 101, the end of the inner tube 101 away from the structural assembly 201 passes through the outer tube 102, so the position of the supporting fixture can be changed to the end of the inner tube 101 extending out of the outer tube 102.
[0081] In this embodiment, in the process of inserting the outer tube 102 into the inner side of the inner tube 101, by changing the supporting position of the supporting tooling, it is possible to avoid the supporting tooling from causing obstruction and interference to the outer tube 102, and enable the supporting tooling to continue to provide support for the inner tube 101.
[0082] In some embodiments provided by the present invention, after the outer tube 102 is connected to the housing 202, the method further includes:
[0083] S230 , supporting the outer tube 102 .
[0084] Specifically, the outer tube 102 is hoisted by using a hoisting device, and after the outer tube 102 is docked and connected with the shell 202 of the power generation device 2, the outer tube 102 is supported by a supporting tool.
[0085] In this embodiment, the outer tube 102 is supported to avoid deformation or damage at the connection between the outer tube 102 and the housing 202 of the power generation device 2 due to the deadweight of the outer tube 102 .
[0086] In some embodiments provided by the present invention, before the inner tube 101 is plugged into the core assembly 301 inside the reactor device 3, the following steps are further included:
[0087] S305 , extending at least a portion of the fixing device 4 between the inner tube 101 and the outer tube 102 , so that the fixing device 4 supports the inner tube 101 and the outer tube 102 .
[0088] Specifically, the fixing device 4 is supported between the inner tube 101 and the outer tube 102, so that the inner tube 101 and the outer tube 102 can be mutually limited in the radial direction. In this way, the supporting fixture of the inner tube 101 can be removed, so that the supporting fixture of the outer tube 102 can be used to support the outer tube 102 and the inner tube 101 together, avoiding interference between the supporting fixture of the inner tube 101 and the reactor device 3 during the plugging process of the inner tube 101 and the core assembly 301.
[0089] S310 , after the inner tube 101 enters the outer shell 302 to a preset depth, the fixing device 4 is removed.
[0090] Specifically, after the inner tube 101 enters the outer shell 302 to a preset depth, the inner tube 101 and the core assembly 301 are plugged into each other at a preset distance, and there is a spacing between the end face of the outer tube 102 and the reactor device 3. This spacing is greater than or equal to the axial dimension of the fixing device 4 in the inner tube 101 to facilitate the removal of the fixing device 4 and avoid the problem that the fixing device 4 cannot be removed after the outer tube 102 is docked with the outer shell 302.
[0091] In some embodiments provided by the present invention, when the power generation device 2, the inner tube 101 and the outer tube 102 are moved close to the reactor device 3 by the transport trolley, the support tool is installed on the transport trolley and used to support the outer tube 102. A fixing device 4 is provided between the outer tube 102 and the inner tube 101.
[0092] In some embodiments provided by the present invention, the fixing device 4 includes two half-ring structures.
[0093] Accordingly, at least part of the fixing device 4 is extended between the inner tube 101 and the outer tube 102, including:
[0094] S306 , sleeve the two half-ring structures onto the outer side of the inner tube 101 , and connect the two half-ring structures via threaded fasteners to form an annular structure, so as to support the outer tube 102 via the annular structure.
[0095] Specifically, two semi-ring structures are respectively buckled on both sides of the inner tube 101, and the two semi-ring structures are butted, and then the two semi-ring structures are connected by threaded fasteners to form an annular structure. The inner diameter of the annular structure is greater than or equal to the outer diameter of the inner tube 101, and the outer diameter of the annular structure is less than or equal to the inner diameter of the outer tube 102. By setting up two semi-ring structures, when it is necessary to remove the semi-ring structure from the inner tube 101, the threaded fasteners of the two semi-ring structures can be directly loosened to completely detach the two semi-ring structures, without removing the fixing device 4 from the end of the inner tube 101, so that the fixing device 4 can be removed when the inner tube 101 extends into the interior of the reactor device 3.
[0096] In some embodiments provided by the present invention, before connecting the outer tube 102 to the outer shell 302 of the reactor device 3, the method further includes:
[0097] S405, detecting the coaxiality of the outer tube 102 and the inner tube 101, and the parallelism between the flange surface of the outer tube 102 and the flange surface of the outer shell 302, and adjusting the outer tube 102 and the power generation device 2 when at least one of the coaxiality and the parallelism does not meet the preset value.
[0098] Specifically, when at least one of the coaxiality error and the parallelism error exceeds the precision requirement, the outer tube 102 and the power generation device 2 are adjusted, for example, the deflection angle of the outer tube 102 can be adjusted, or the position or deflection angle of the power generation device 2 can be adjusted, so that both the coaxiality and the parallelism meet the corresponding precision requirements, thereby ensuring the installation accuracy of the air-cooled micro-reactor. The position of the power generation device 2 can be a height position or a horizontal position.
[0099] In some embodiments provided by the present invention, at least one of a guide rod and a positioning pin is provided on the outer side of the inner tube 101. The guide rod or the positioning pin is parallel to the axial direction of the inner tube 101, and a guide hole that slides with the guide rod, or a positioning hole that positions with the positioning pin is provided on the core assembly 301. In the process of plugging the inner tube 101 with the core assembly 301, the guide rod on the inner tube 101 slides with the guide hole, or the positioning pin positions with the positioning hole, which can make the inner tube 101 and the core assembly 301 plugged smoothly on the one hand, and ensure the relative position accuracy of the inner tube 101 and the core assembly 301 on the other hand.
[0100] In some embodiments provided by the present invention, at least one of the inner tube 101 and the outer tube 102 includes a bellows section. By providing the bellows section, the inner tube 101 and the outer tube 102 can absorb thermal expansion, thereby avoiding the problem that the connection structure between the inner tube 101 and the power generation device 2, and the connection structure between the outer tube 102 and the shell 202 and the outer tube 102 are damaged due to excessive force. On the other hand, during the installation of the inner tube 101 and the outer tube 102, the bellows can absorb the impact between the inner tube 101 and the power generation device 2 or the reactor device 3, and between the outer tube 102 and the power generation device 2 or the reactor device 3 during the installation process, thereby avoiding the above components being damaged due to the impact.
[0101] In some embodiments provided by the present invention, the above-mentioned installation method can be operated by a manipulator or a robot, or can be operated manually.
[0102] An air-cooled micro-reactor is also provided in an embodiment of the present invention.
[0103] Specifically, the air-cooled micro-reactor is installed based on the air-cooled micro-reactor main pipeline installation method as described above.
[0104] It should be noted that the gas-cooled micro-reactor is installed based on the gas-cooled micro-reactor main pipeline installation method, and also has corresponding advantages, so it will not be elaborated on.
[0105] Optionally, the gas-cooled micro-reactor includes a reactor device 3, a power generation device 2 and a main pipeline 1. The reactor device 3 includes an outer shell 302 and a core assembly 301 disposed in the outer shell 302.
