Description

Technical Field

[0001] This invention relates to the field of boiler technology, and more specifically to a boiler with a corrugated inner liner. Background Technology

[0002] The corrugated inner liner of the boiler optimizes airflow and temperature distribution within the furnace, effectively preventing coking. However, in related technologies, the corrugated inner liner is subjected to high-temperature flame radiation and flue gas erosion over a long period, causing its wall thickness to gradually decrease. When the wall thickness wears down to a certain extent, reaching a safety limit, the boiler must be shut down and the inner liner replaced promptly to ensure safe operation. The corrugated inner liner is typically installed using full butt welding to seal the gaps and ensure a stable connection between the inner liner and the furnace shell. However, this method requires destructive cutting to remove the corrugated inner liner from the boiler shell. This destructive disassembly method is not only complex and time-consuming, making disassembly inconvenient and significantly impacting efficiency, but it can also damage the boiler shell during the cutting process, affecting its structural integrity and subsequent performance, further increasing maintenance difficulty and cost.

[0029] Embodiments of the present invention are described in detail below, examples of which are illustrated in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.

[0030] like Figures 1 to 12 As shown, the present invention provides a boiler with a corrugated inner liner 100, which includes a shell, a corrugated inner liner 100, and an installation device 11. The installation device 11 includes a fixing ring 111, a rotating ring 112, a docking ring 113, and a limiting component 114. The fixing ring 111 is disposed on the shell, and the rotating ring 112 is coaxially disposed with the fixing ring 111. The rotating ring 112 is rotatable relative to the fixing ring 111. The rotating ring 112 is provided with a lifting groove 1121, which extends along the rotating ring. The 112 extends in the combined radial and circumferential directions; the docking ring 113 is disposed in the corrugated inner liner 100 and is accommodated in the inner cavity of the fixing ring 111, and the docking ring 113 is provided with a slot 1131; the limiting assembly 114 includes a first guide rod 1141 and a first insert 1142 connected to each other, the first guide rod 1141 is slidably disposed in the lifting groove 1121, and the first insert 1142 is slidably connected to the fixing ring 111 along the radial direction of the fixing ring 111. The first guide rod 1141 has a first position and a second position in the lifting groove 1121. When the first guide rod 1141 is in the first position, the first insert 1142 is inserted into the slot 1131 to connect the docking ring 113 and the fixing ring 111; when the first guide rod 1141 is in the second position, the first insert 1142 is disengaged from the slot 1131.

[0031] Specifically, the shell, as the basic supporting structure of the boiler, provides a stable installation space for internal components. It possesses good strength and sealing properties, effectively resisting the pressure and heat generated during boiler operation, ensuring the safety and reliability of the entire system. The corrugated inner liner 100, with its inherent concave-convex structure, effectively disrupts the smooth flow of flue gas, generating strong disturbances and eddies. This acts as a flow guide structure, allowing for more thorough and uniform heat exchange between the high-temperature flue gas and the inner liner wall, preventing excessive heat concentration in localized areas and reducing the risk of coking. Furthermore, during boiler start-up, shutdown, and operation, the corrugated inner liner 100 undergoes thermal expansion and contraction due to temperature changes. At this time, its corrugated structure acts like a spring, providing axial elasticity and effectively absorbing thermal stress. This effectively prevents the inner liner from deforming or being damaged due to excessive stress, maintaining the integrity and smoothness of the airflow channel and avoiding flow dead zones and coking caused by structural deformation.

[0032] Research by technicians has revealed that, compared to a straight cylindrical inner liner, the corrugated inner liner 100 can significantly increase the surface area of ​​the inner liner within the same space, providing more contact surface for heat transfer. This means that heat transfer is more efficient, which can reduce flue gas problems more quickly and allow ash to cool and solidify before contacting the wall surface, making it less likely to adhere and coke in a molten state.

[0033] The mounting device 11 allows for convenient disassembly and assembly of the inner liner. Compared to welding, it offers advantages such as ease of disassembly and assembly, high flexibility, and reliable fixation, significantly improving boiler maintenance and repair efficiency. The fixing ring 111 is securely mounted on the shell, serving as the fundamental fixing component of the entire mounting device 11. The fixing ring 111 provides a reliable mounting reference and support for other components, maintaining structural stability and reliability. The mating ring 113 is mounted on the corrugated inner liner 100. The shape and size of the mating ring 113 match the inner cavity of the fixing ring 111, allowing it to be precisely accommodated within the inner cavity of the fixing ring 111.

[0034] The rotating ring 112 is coaxially arranged with the fixed ring 111 and can rotate flexibly relative to the fixed ring 111. The extension direction of the lifting groove 1121 on the rotating ring 112 is not simply radial or circumferential, but extends along the combined direction of the radial and circumferential directions of the rotating ring 112. During the rotation of the rotating ring 112 relative to the fixed ring 111, the first guide rod 1141 moves with the rotation of the rotating ring 112 under the guidance of the lifting groove 1121, and drives the first insertion block 1142 to slide relative to the fixed ring 111 in the radial direction, thereby realizing the insertion and disengagement with the slot 1131 on the docking ring 113.

[0035] During the installation of the corrugated inner liner 100, the operator can rotate the rotating ring 112 in the first direction. The first guide rod 1141 moves from the second position of the lifting groove 1121 toward the first position. At this time, under the guidance of the lifting groove 1121, the first insert block 1142 will gradually insert into the slot 1131 of the docking ring 113. The docking ring 113 and the fixing ring 111 are firmly connected through the tight cooperation of the first insert block 1142 and the slot 1131, thereby firmly installing the corrugated inner liner 100 in the shell.

[0036] During the disassembly of the corrugated inner liner 100, the operator can rotate the rotating ring 112 in the second direction. The first guide rod 1141 moves from the first position of the lifting groove 1121 to the second position. Under the guidance of the lifting groove 1121, the first insert 1142 will gradually move away from the slot 1131 of the docking ring 113 until the first insert 1142 is disengaged from the docking ring 113. At this time, the connection between the docking ring 113 and the fixing ring 111 is released, and the corrugated inner liner 100 can be easily disassembled from the shell.

[0037] It should be noted that the first direction and the second direction are two opposite directions. For example, the first direction can be the clockwise direction of the fixing ring 111, and the second direction corresponds to the counterclockwise direction of the fixing ring 111. Of course, in other embodiments of the present invention, the first direction and the second direction can also be other directions, which will not be elaborated here.

[0038] In summary, the boiler with corrugated inner liner 100 provided by the present invention, through the installation device 11, can not only improve the performance of the boiler, but also facilitate disassembly and assembly, greatly simplifying the disassembly and assembly process and helping to improve work efficiency.

[0039] In some embodiments, multiple limiting components 114 are provided, and the multiple limiting components 114 are spaced apart along the circumferential direction of the rotating ring 112. The multiple limiting components spaced apart along the circumferential direction of the rotating ring 112 can connect and fix the docking ring 113 and the fixing ring 111 from multiple different positions. Each limiting component bears a portion of the connection force, collectively distributing various forces that may be generated during boiler operation. Compared to a single limiting component, this multi-point connection method greatly reduces the stress load on individual components, effectively preventing loosening or damage to the connection due to excessive local stress, thereby significantly improving the connection stability of the entire installation device 11 and ensuring that the corrugated inner liner 100 maintains a stable installation state during boiler operation.

[0040] During the use of the boiler, multiple limiting components are spaced apart circumferentially along the rotating ring 112, which helps to balance the force on each part during boiler operation, reduce stress concentration caused by structural asymmetry, and extend the service life of the installation device 11 and the entire boiler.

[0041] In some embodiments, the rotating ring 112 is provided with a first arc-shaped groove 1122, which extends along an arc trajectory centered on the center of the rotating ring 112. The first arc-shaped groove 1122 is connected to the lifting groove 1121 in a one-to-one correspondence. That is, when the rotating ring 112 starts to rotate, the first guide rod 1141 is first subjected to a combined radial and circumferential force in the lifting groove 1121 and begins to move along the lifting groove 1121. During the movement, when the first guide rod 1141 approaches the connection between the lifting groove 1121 and the first arc-shaped groove 1122, the rotating ring 112 will drive the first guide rod 1141 to move again, so that the first guide rod 1141 enters the first arc-shaped groove 1122. Since the first arc-shaped groove 1122 is arc-shaped, when guiding the movement of the first guide rod 1141, it can make the movement direction of the first guide rod 1141 gradually and smoothly change, avoiding the impact and jamming caused by sudden changes in direction. This smooth transition makes the movement of the first guide rod 1141 between the lifting groove 1121 and the first arc-shaped groove 1122 smoother, greatly improving the flexibility and stability of the movement of the limiting component.

[0042] Furthermore, the lifting groove 1121 has a first end 11211 and a second end 11212. When the first guide rod 1141 is located at the first end 11211 of the lifting groove 1121, the first guide rod 1141 is in the first position; when the first guide rod 1141 is located at the second end 11212 of the lifting groove 1121, the first guide rod 1141 is in the second position. The first arc-shaped groove 1122 is connected to the first end 11211 of the lifting groove 1121. When the first guide rod 1141 moves from the first end 11211 of the lifting groove 1121 to the first arc-shaped groove 1122, the first arc-shaped groove 1122 can be used to limit the first guide rod 1141, preventing the first guide rod 1141 from moving back to the second position. The positions of the first guide rod 1141 and the first insert 1142 are locked to prevent the first insert 1142 from disengaging from the slot 1131, thereby reducing the risk of the docking ring 113 disengaging from the fixing ring 111.

[0043] like Figure 2 , Figure 3 and Figure 4 As shown, in this embodiment, the limiting component further includes a first guide block 1143. The fixing ring 111 and / or the rotating ring 112 are provided with a first guide groove 1113. The first guide groove 1113 extends along the radial direction of the fixing ring 111. The first guide block 1143 is connected to the first insertion block 1142. The first guide block 1143 is movably disposed in the first guide groove to limit the moving direction of the first insertion block 1142.

[0044] Furthermore, the first insert block 1142 is provided with a U-shaped groove 11421, and the docking ring 113 is provided with a positioning part 1132 that matches the U-shaped groove 11421. When the first guide rod 1141 is in the first position, the U-shaped groove 11421 on the first insert block 1142 cooperates with the positioning part 1132 on the docking ring 113 to realize the connection between the docking ring 113 and the fixing ring 111.

[0045] Furthermore, a first guide block 1143 is disposed between the first insert block 1142 and the first guide rod 1164. When the first guide rod 1141 is subjected to an external force (such as the force generated by the rotation of the rotating ring 112), the force is transmitted to the first insert block 1142 through the first guide block 1143, causing the first insert block 1142 to move accordingly. Simultaneously, the sliding of the first guide block 1143 within the first guide groove is restricted by the guide groove, ensuring accurate force transmission direction, thereby allowing the first insert block 1142 to move in a predetermined radial direction.

[0046] Optionally, the first guide block 1143, the first insert block 1142, and the first guide rod 1164 can be configured as a single integral piece.

[0047] like Figure 3 and Figure 4 As shown, in some embodiments, the fixed ring 111 is provided with an annular groove 1111, and the rotating ring 112 is provided with an annular protrusion 1123. The annular protrusion 1123 is adapted to the annular groove 1111 to limit the rotation direction of the rotating ring 112, laying a solid foundation for the stable operation and reliable operation of the entire device.

[0048] like Figure 5 and Figure 6 As shown, in some embodiments, the mounting device 11 further includes a connecting assembly 115, which includes a first elastic element 1151 and a post 1152. The fixing ring 111 has a mounting cavity 1112, and the post 1152 is movably disposed within the mounting cavity 1112. The two ends of the first elastic element 1151 are correspondingly connected to the post 1152 and the inner wall of the mounting cavity 1112. The rotating ring 112 has a insertion hole 1124 that matches the post 1152. When the first guide rod 1141 is in the first position, the post 1152 is inserted into the insertion hole 1124 to connect the fixing ring 111 and the rotating ring 112.

[0049] Specifically, the insertion post 1152 is adapted to the shape of the mounting cavity 1112. One end of the insertion post 1152 is connected to the first elastic element 1151, and the other end of the insertion post 1152 is used to insert into the insertion hole 1124. Under the action of the first elastic element 1151, the insertion post 1152 is always in a dynamic equilibrium state, ready to respond to the position change of the first guide rod 1141 at any time to complete the insertion or separation action with the insertion hole 1124.

[0050] When the first guide rod 1141 is in the first position, under the elastic force of the first elastic element 1151, the insertion post 1152 is pushed out of the mounting cavity 1112 and inserted into the corresponding insertion hole 1124 on the rotating ring 112. Due to the tight fit between the insertion post 1152 and the insertion hole 1124, a stable connection is formed between the fixed ring 111 and the rotating ring 112, and their relative positions are fixed, preventing relative rotation and ensuring the stable installation of the corrugated inner liner 100.

[0051] When the first guide rod 1141 leaves the first position, it is subjected to a force from the rotating ring 112 on the insertion post 1152. This force overcomes the elastic force of the first elastic element 1151, causing the insertion post 1152 to return into the mounting cavity 1112. As the insertion post 1152 is pulled out, the connection between the fixing ring 111 and the rotating ring 112 is released, and the two regain their relative rotational freedom, thereby facilitating the removal of the first insertion block 1142 from the docking ring 113, realizing the separation of the docking ring 113 from the fixing ring 111, and completing the disassembly of the corrugated inner liner 100.

[0052] Optionally, the first elastic element 1151 can be configured as a spring.

[0053] In some embodiments, multiple mounting cavities 1112, insertion holes 1124, and connecting assemblies 115 are provided. The mounting cavities 1112 are spaced apart along the circumferential direction of the fixing ring 111. Each connecting assembly 115 corresponds to one mounting cavity 1112, and each insertion hole 1124 corresponds to one connecting assembly 115. Multiple connecting assemblies 115 operate simultaneously, forming a multi-point stable connection, which can withstand greater force and torque compared to a single connecting assembly 115. During device operation, even under significant external impact or vibration, the cooperation between multiple insertion posts 1152 and insertion holes 1124 maintains a stable connection between the fixing ring 111 and the rotating ring 112, preventing loosening or detachment.

[0054] like Figures 7 to 9 As shown, in some embodiments, the mounting device 11 further includes a positioning component 116, which includes a fixed base 1161 and a positioning slider 1162. The positioning slider 1162 is slidably connected to the fixed base 1161 along the radial direction of the docking ring 113. A second elastic element 1163 is provided between the positioning slider 1162 and the positioning base. The fixed base 1161 is detachably disposed on one of the docking ring 113 and the rotating ring 112. The other of the docking ring 113 and the rotating ring 112 is provided with a positioning groove 1125. The positioning slider 1162 is used to insert into the positioning groove 1125 under the action of the second elastic element 1163.

[0055] In this embodiment, the positioning groove 1125 can be disposed on the rotating ring 112, and the fixing seat 1161 and the positioning slider 1162 can be disposed on the docking ring 113. During the rotation of the rotating ring 112, the inner wall of the rotating ring 112 will abut against the positioning slider 1162. When the positioning groove 1125 on the rotating ring 112 rotates to the position corresponding to the positioning slider 1162, the positioning slider 1162 moves toward the positioning groove 1125 under the elastic force of the second elastic member 1163, so as to realize the positioning of the rotating ring 112.

[0056] As can be imagined, in some embodiments of the present invention, the positioning groove 1125 may also be provided on the docking ring 113, and correspondingly, the fixing seat 1161 and the positioning slider 1162 may be provided on the rotating ring 112.

[0057] Furthermore, the fixed base 1161 is provided with a guide rod 1164, and the positioning slider 1162 is provided with a guide cavity 11621 that matches the guide rod 1164. The second elastic element 1163 is sleeved on the guide rod 1164. The shape and size of the guide cavity 11621 are closely matched with the guide rod 1164, with a small gap between them. This ensures that the positioning slider 1162 can slide smoothly along the guide rod 1164, and effectively prevents the positioning slider 1162 from shaking or deviating during the sliding process. This ensures the directionality and stability of the positioning slider 1162 during the movement and improves the working accuracy of the entire positioning assembly 116.

[0058] Optionally, two guide rods 1164 are provided, arranged side by side. Correspondingly, two guide cavities 11621 are also provided to prevent the positioning slider 1162 from shaking or shifting during sliding.

[0059] Furthermore, the positioning slider 1162 has a semi-circular head 11623, and the positioning groove 1125 is set as a semi-circular groove that matches the semi-circular head 11623 to facilitate the snap-fit ​​fixing of the positioning slider 1162.

[0060] In some embodiments, the fixing base 1161 is provided with a fixing groove 11611, and the positioning component 116 further includes a third elastic member 1165 and two fixing blocks 1166. The two ends of the third elastic member 1165 are correspondingly connected to the two fixing blocks 1166. The two fixing blocks 1166 are arranged opposite to each other and are located in the positioning groove 1125. The fixing block 1166 has a snap-fit ​​connector 11661. The mating ring 113 is provided with a snap-fit ​​groove 1133. The snap-fit ​​connector 11661 is used to snap into the snap-fit ​​groove 1133 to connect the fixing base 1161.

[0061] Specifically, during the installation of the fixing base 1161, the two fixing blocks 1166 can move towards each other and press against the third elastic element 1165 located between the two fixing blocks 1166, so that the fixing blocks 1166 are locked in the fixing groove 11611. The mating ring 113 is provided with a slot 1133. During the movement of the two fixing blocks 1166 towards each other, the fixing blocks 1166 will drive the locking connectors 11661 to move towards each other, so that the distance between the two locking connectors 11661 is reduced, and the locking connectors 11661 are filled into the slot 1133, so as to realize the installation of the fixing blocks 1166.

[0062] Furthermore, the fixing block 1166 has a pressing plate 11662, which is connected to the snap connector 11661. The pressing plate 11662 is movably disposed in the fixing groove 11611. Under the elastic force of the third elastic member 1165, the two pressing plates 11662 are attached to the two opposite side walls of the fixing groove 11611 to realize the connection between the fixing block 1166 and the fixing seat 1161.

[0063] In some embodiments, the mounting device 11 further includes a reinforcing component 117, which includes a guide frame 1171, a stop block 1172, and a limiting strip 1173. A second guide rod 1126 is provided on the rotating ring 112, and the second guide rod 1126 is slidably disposed within the guide frame 1171. The stop block 1172 is fixedly connected to the guide frame 1171, and the limiting strip 1173 is disposed on the fixing ring 111. The stop block 1172 is slidably connected to the limiting strip 1173 along the radial direction of the fixing ring 111. The reinforcing component 117 can re-fix the docking ring 113 after it has been engaged with the fixing ring 111, reducing the risk of the docking ring 113 detaching from the fixing ring 111.

[0064] The second guide rod 1126 has a third position and a fourth position within the guide frame 1171. When the second guide rod 1126 is in the third position, the guide frame 1171 drives the stop block 1172 to move along the limiting strip 1173 until the stop block 1172 abuts against the axial end face of the docking ring 113. When the second guide rod 1126 is in the fourth position, the guide frame 1171 drives the stop block 1172 to move along the limiting strip 1173, so that the stop block 1172 moves away from the docking ring 113.

[0065] Specifically, the guide frame 1171 has a smooth guide channel 11711 inside, and the second guide rod 1126 on the rotating ring 112 can be adapted to the guide channel 11711 inside the guide frame 1171 and can slide relative to the guide frame 1171. That is, during the rotation of the rotating ring 112, the second guide rod 1126 can slide freely inside the guide frame 1171, while the guide frame 1171 can also restrict and guide the movement direction of the second guide rod 1126, ensuring the stability and accuracy of the rotation of the rotating ring 112.

[0066] The stop block 1172 is fixedly connected to the guide frame 1171, for example, by welding, bolting, or snap-fit, ensuring that there is no relative movement between the stop block 1172 and the guide frame 1171. A limiting strip 1173 is provided on the fixing ring 111. The limiting strip 1173 can be made of the same material as the fixing ring 111, or it can be made separately from other materials and then fixed to the fixing ring 111. The stop block 1172 is slidably connected to the limiting strip 1173 along the radial direction of the fixing ring 111, that is, the stop block 1172 can move along the radial direction of the fixing ring 111 on the limiting strip 1173, achieving further fixation and limiting of the mating ring 113.

[0067] During use, the operator can rotate the rotating ring 112, which drives the second guide rod 1126 to slide within the guide frame 1171. As the second guide rod 1126 moves, the guide frame 1171 transmits the motion to the stop block 1172, causing the stop block 1172 to move radially toward the center of the docking ring 113 along the fixed ring 111. During this movement, the stop block 1172 can accurately abut against the end face of the docking ring 113. Once the stop block 1172 is in tight contact with the end face of the docking ring 113, the rotation of the rotating ring 112 is stopped. At this point, the reinforcing assembly 117 completes the fixing of the docking ring 113, and the docking ring 113 is firmly locked onto the fixed ring 111, unable to move in the axial direction, thus achieving positional fixation of the docking ring 113.

[0068] When it is necessary to disassemble or adjust the docking ring 113, the operator can rotate the rotating ring 112 in the opposite direction. The second guide rod 1126 slides to the fourth position within the guide frame 1171, causing the stop block 1172 to move away from the docking ring 113 along the radial direction of the fixing ring 111. When the stop block 1172 moves to a sufficiently far position and is completely separated from the docking ring 113, the docking ring 113 is no longer subject to the fixing force of the reinforcing component 117. At this time, the disassembly or adjustment of the docking ring 113 can be easily performed.

[0069] like Figure 11 and Figure 12 As shown, in some embodiments, the guide frame 1171 has a second arc-shaped groove 11712 and an inclined groove 11713, the second arc-shaped groove 11712 and the inclined groove 11713 are connected, and the second arc-shaped groove 11712 is coaxially arranged with the rotation. Specifically, when the second guide rod 1126 is in the third position within the guide frame 1171, the second guide rod 1126 is located at the connection between the inclined groove 11713 and the second arc-shaped groove 11712; when the second guide rod 1126 is in the fourth position within the guide frame 1171, the second guide rod 1126 is located within the inclined groove 11713, and at the end of the inclined groove 11713 away from the second arc-shaped groove 11712.

[0070] The second arc groove 11712 extends along an arc trajectory centered on the center of the rotating ring 112, thereby making the movement of the second guide rod 1126 in the guide frame 1171 more compatible with the rotational movement of the rotating ring 112.

[0071] Furthermore, the docking ring 113 has a first side and a second side. The first side is connected to the corrugated inner liner 100. The stop block 1172 is located on the first side of the docking ring 113 to limit the docking ring 113 and prevent the docking ring 113 from separating from the fixing ring 111.
