Description

Technical Field

[0001] The utility model relates to the technical field of boiler superheaters, and specifically relates to a high-temperature superheater for boilers. Background Technique

[0002] A boiler is an energy conversion device. The energy input into the boiler includes forms such as chemical energy in fuel, electrical energy, and thermal energy of high-temperature flue gas. After being converted by the boiler, it outputs steam, high-temperature water, or organic heat carriers with a certain amount of thermal energy, which are widely used in thermal power plants, ships, locomotives, and industrial and mining enterprises. When the temperature in the boiler is too high, an explosion accident is likely to occur. Therefore, a high-temperature superheater needs to be set in the boiler.

[0003] When the existing boiler high-temperature superheater is in use, if the internal steam impact force is too large, it is easy to cause a certain vibration to the pipe body. Under the vibration for a long time, the position may become loose, resulting in a reduction in the service life of the boiler superheater. For this reason, we propose a high-temperature superheater for boilers. Content of the Utility Model

[0004] The purpose of the utility model is to provide a high-temperature superheater for boilers to solve the problems raised in the above background technique.

[0005] To achieve the above purpose, the utility model provides the following technical solution: A high-temperature superheater for boilers, including a furnace body, a frame, a pipeline assembly, a support assembly, and a limit assembly. A frame is arranged at the bottom of the furnace body, and a pipeline assembly is arranged inside the frame. Support assemblies are arranged on both sides of the pipeline assembly, and a limit assembly is arranged on the top of the pipeline assembly. The limit assembly includes a cross plate, a limit groove, a second fastener, and a connecting rod. A limit groove is arranged in the middle of the cross plate. Second fasteners are arranged on both sides of the cross plate, and a connecting rod is arranged at the bottom of the second fastener. The support assembly includes a mounting plate, a clamping block, and a first fastener. A clamping block is arranged inside the mounting plate, and a first fastener is arranged on the end face of the mounting plate.

[0006] Further, the cross plate and the pipeline assembly form a clamping structure through the limit groove, and the number of limit grooves is the same as the number of pipeline assemblies.

[0007] Further, the cross plate and the second fastener form a threaded structure through the connecting rod, and the cross plate wraps the pipeline assembly.

[0008] Further, the mounting plate wraps the pipeline assembly through the clamping block, and the mounting plate and the first fastener are in threaded connection.

[0009] Further, the pipeline assembly includes a pipe body, heat dissipation fins, and a fan. Heat dissipation fins are arranged on the outer side of the middle of the pipe body, and a fan is arranged behind the heat dissipation fins.

[0010] Furthermore, the heat dissipation fins wrap the pipe body, and the heat dissipation fins cooperate with the fan.

[0011] Compared with the prior art, the beneficial effects of the present utility model are as follows: The pipe body is limited and installed through the clamping blocks in the mounting plate, ensuring its free expansion while taking into account the flatness of the pipe body. Subsequently, the top and bottom ends of the pipe body are secondarily restricted by the limiting grooves in the cross plate. Since the number of limiting grooves is the same as the number of pipe bodies, it is convenient to be embedded one by one, and each pipe can be limited. The cross plate is integrally installed and spliced through the connecting rods and the second fasteners at both ends, which is convenient for subsequent disassembly and maintenance. Finally, a plurality of circular heat dissipation fins are arranged in the middle of the outer side of the pipe body, and the cooperation with the fan facilitates the discharge of the heat outside the heat dissipation fins.

[0012] The number of the limiting grooves is the same as the number of the pipe bodies, so that it is convenient to be embedded one by one, and each pipe can be limited. The cross plate is integrally installed and spliced through the connecting rods and the second fasteners at both ends, which is convenient for subsequent disassembly and maintenance. The cooperation with the mounting plates on both sides of the bottom end forms a double limiting effect, effectively reducing the probability of pipe body damage.

[0013] The inside of the mounting plate is provided with groove-shaped clamping blocks matching the pipe body. Thus, the pipe body is limited and installed through the clamping blocks in the mounting plate. The size of the clamping blocks is larger than that of the pipe body, and the inner wall of the clamping blocks is provided with a heat insulation layer. The heat insulation layer is aerogel felt, so that the heat insulation layer has high tensile and compressive strength and is not easy to deform and fall off. Therefore, while ensuring its free expansion, the flatness of the pipe body is taken into account. At the same time, the first fastener in the middle can reduce stress concentration. Subsequently, the top and bottom ends of the pipe body are secondarily restricted by the limiting grooves in the cross plate, increasing the stable use. Description of the Drawings

[0018] Such as Figure 1-2As shown in the figure, a high-temperature superheater for a boiler includes a furnace body 1, a frame 2, a pipe assembly 3, a support assembly 4, and a limit assembly 5. A frame 2 is provided at the bottom of the furnace body 1, and a pipe assembly 3 is provided inside the frame 2. Support assemblies 4 are provided on both sides of the pipe assembly 3, and a limit assembly 5 is provided on the top of the pipe assembly 3. The pipe assembly 3 includes a pipe body 301, heat dissipation fins 302, and a blower 303. Heat dissipation fins 302 are provided on the outer side of the middle of the pipe body 301, and a blower 303 is provided behind the heat dissipation fins 302. The heat dissipation fins 302 wrap the pipe body 301, and the heat dissipation fins 302 cooperate with the blower 303. A plurality of circular heat dissipation fins 302 are provided in the middle of the outer side of the pipe body 301. Therefore, the temperature generated during the operation of the pipe body 301 is transferred to the heat dissipation fins 302, and a blower 303 is provided behind the pipe body 301. The blower 303 is arranged inside the frame 2 to exhaust air, so as to facilitate the discharge of the heat outside the heat dissipation fins 302 and dissipate heat from the superheater.

[0019] As Figure 3As shown in the figure, a high-temperature superheater for a boiler, the limiting component 5 includes a cross plate 501, a limiting groove 502, a second fastener 503 and a connecting rod 504. A limiting groove 502 is provided in the middle of the cross plate 501, and second fasteners 503 are provided on both sides of the cross plate 501. A connecting rod 504 is provided at the bottom of the second fastener 503. The cross plate 501 forms a clamping structure with the pipeline component 3 through the limiting groove 502, and the number of the limiting grooves 502 is the same as the number of the pipeline components 3. The setting of the limiting groove 502 is used to cooperate with the cross plate 501. By embedding both sides of the pipe body 301 into the limiting groove 502 of the cross plate 501, while achieving the limiting effect, the superheater pipe is supported, ensuring the stability of the superheater pipeline. The cross plate 501 forms a threaded structure with the connecting rod 504 and the second fastener 503, and the cross plate 501 wraps the pipeline component 3. The number of the limiting grooves 502 is the same as the number of the pipe bodies 301, so as to facilitate corresponding embedding one by one, and limit each pipe. The cross plate 501 is integrally installed and spliced through the connecting rods 504 and the second fasteners 503 at both ends, and is convenient for subsequent disassembly and maintenance. Cooperating with the mounting plates 401 at both sides of the bottom end forms a double limiting effect, effectively reducing the damage probability of the pipe body 301. The supporting component 4 includes a mounting plate 401, a clamping block 402 and a first fastener 403. A clamping block 402 is provided inside the mounting plate 401, and a first fastener 403 is provided on the end face of the mounting plate 401. The mounting plate 401 wraps the pipeline component 3 through the clamping block 402, and a threaded connection is between the mounting plate 401 and the first fastener 403. A groove-shaped clamping block 402 matching the pipe body 301 is provided inside the mounting plate 401. Thus, the pipe body 301 is limited and installed through the clamping block 402 inside the mounting plate 401. The size of the clamping block 402 is larger than that of the pipe body 301, and a heat insulation layer is provided on the inner wall of the clamping block 402. The heat insulation layer is aerogel felt, so that the heat insulation layer has high tensile and compressive strength and is not easy to deform and fall off. Therefore, while ensuring its free expansion, the flatness of the pipe body 301 is taken into account. At the same time, the first fastener 403 in the middle can reduce stress concentration. Subsequently, the top and bottom ends of the pipe body 301 are secondarily limited by the limiting grooves 502 in the cross plate 501, increasing the stable use.

[0020] Working principle: First, the pipe body 301 is installed and limited by the clamping block 402 in the mounting plate 401. The size of the clamping block 402 is larger than that of the pipe body 301, and a heat insulation layer is provided on the inner wall of the clamping block 402. Therefore, while ensuring its free expansion, the flatness of the pipe body 301 is taken into account. At the same time, the first fastener 403 in the middle is used to reduce stress concentration. Subsequently, the top and bottom ends of the pipe body 301 are secondarily restricted by the limiting grooves 502 in the cross plate 501. Since the number of the limiting grooves 502 is the same as that of the pipe body 301, it is convenient to be embedded one by one, and the limit can be formed for each pipe. The cross plate 501 is integrally installed and spliced through the connecting rods 504 and the second fasteners 503 at both ends, which is convenient for subsequent disassembly and maintenance, reducing the damage probability of the pipe body 301. Finally, a plurality of circular heat dissipation fins 302 are arranged in the middle of the outer side of the pipe body 301. Therefore, the temperature generated during the operation of the pipe body 301 is transferred to the heat dissipation fins 302, and a fan 303 is arranged behind the pipe body 301. The fan 303 is arranged inside the frame 2 for exhaust, facilitating the discharge of the heat outside the heat dissipation fins 302 and improving the service life.
