Abstract
Description
Technical Field
[0001] This invention belongs to the field of heat exchanger technology, specifically relating to a wound tube heat exchanger for carbon black production. Background Technology
[0002] Carbon black production involves the incomplete combustion and thermal cracking of raw materials such as heavy oil, coal tar, and natural gas under high temperature and oxygen deficiency to produce extremely fine carbon powder. This powder is mainly used in industries such as tire rubber, plastics, and inks for reinforcement, coloring, and conductivity. Among these materials, the wound tube heat exchanger is the "heart energy-saving equipment" of the carbon black production line. It is used for high-temperature flue gas waste heat recovery, process air preheating, and tail gas cooling, and is suitable for the harsh working conditions of high temperature, large temperature difference, and strong thermal stress in the carbon black process.
[0003] Because there are many devices installed on the side of the heat exchanger, such as temperature measuring tubes, pressure measuring tubes, soot blowing tubes and valves, guardrails are usually installed around the heat exchanger to prevent workers from touching the side devices when passing by or moving workpieces, thus separating the heat exchanger from the outside world and forming a protection.
[0004] However, the guardrails on all four sides of existing heat exchangers are usually one-piece detachable or welded to the sides of the heat exchanger. Their positions and heights are fixed. If the height of the guardrail is too low, the protective effect is not good. If the height of the guardrail is too high, it will easily obstruct the staff's view or operation when they inspect or maintain the side equipment of the heat exchanger, which is inconvenient. Summary of the Invention
[0005] The purpose of this invention is to provide a wound tube heat exchanger for carbon black production, so that the guardrail protecting the heat exchanger can be raised, lowered, and its height adjusted in real time.
[0006] To achieve the above objectives, embodiments of the present invention provide a wound tube heat exchanger for carbon black production, including a heat exchanger body mounted on a base plate, and further including a protective frame, height adjustment components, a barrier frame, and support components. The protective frame is fixedly mounted on the base plate, and the heat exchanger body is located within the protective frame and configured to protect the lower part of the heat exchanger body. Three height adjustment components are provided, all of which are mounted on the protective frame. Three barrier frames are provided, each mounted on one of the three height adjustment components via three abutment plates. The height adjustment components are configured to adjust the height of the barrier frames. The barrier frames are hinged to the abutment plates and can rotate to be perpendicular to the abutment plates or to a horizontally laid-down position. Three support components are provided, all of which are located on the side of the protective frame and configured to support the barrier frames when they are rotated to a vertical or perpendicular position.
[0007] To adjust the height of the barrier frame, the height adjustment assembly further includes a mounting plate, electric cylinders, railings, barrier posts, and a limiting assembly. The mounting plate is fixedly mounted on the protective frame, and two electric cylinders are mounted on the mounting plate. Railings are fixedly mounted on the output ends of both electric cylinders. A plurality of barrier posts are fixedly mounted between the railings, and abutment plates are fixedly mounted on the tops of the barrier posts. The limiting assembly is located on the side of the protective frame and includes a limiting rail and a limiting rod. There are two rails, and both of the limiting rails are fixedly installed on the side of the protective frame. The limiting rods are fixedly installed on the side of the two barrier posts, and the two limiting rods are slidably installed on the side of the two limiting rails. The top of the protective frame has a through groove, and the railing and the barrier posts pass through the through groove of the protective frame. Several stabilizing seats are fixedly installed on the mounting plate. The several stabilizing seats are located directly below the several barrier posts, and the top of the stabilizing seats has a slot that matches the bottom of the barrier post.
[0008] When the barrier is rotated to a vertical or horizontal position, it is ensured that the barrier can be placed stably. Furthermore, the support assembly includes a support frame, a synchronizing rod, a support block, and a plug rod. Two support frames are fixedly installed on the side of the protective frame, and the synchronizing rod is slidably installed through each support frame. Two support blocks are fixedly installed at the top of the barrier. The plug rod is slidably installed on the side of the synchronizing rod. The side of the support block has a support groove adapted to the plug rod. The edge of the support frame is arc-shaped. After the bottom end of the barrier post contacts the slot of the stabilizing seat, when the barrier is rotated to a horizontal position, the bottom end of the barrier contacts the top end of the support frame. When the bottom end of the synchronizing rod contacts the base plate, the top end of the synchronizing rod and the top end of the support frame are at the same horizontal position.
[0009] The significant technical effects of the embodiments of the present invention are as follows: When the heat exchanger body is in use and protected, the lower part of the heat exchanger body is protected by a protective frame. Then, by rotating the barrier to a vertical position, it is kept vertically supported by the support assembly. At this time, the barrier can be moved upward by the height adjustment assembly. After it is moved upward, the upper part of the heat exchanger body can be protected by the barrier. At this time, the middle part of the heat exchanger body can be protected by barrier posts and railings. At this time, most of the side area of the heat exchanger body can be protected. Furthermore, the outward-extending support frame can prevent personnel from getting close to the heat exchanger body when moving items. When it is necessary to repair or observe the side of the heat exchanger body, the barrier is first lowered by adjusting the height to expose the upper part of the heat exchanger body. At this time, there is no obstruction when the workers work on the parts on the side of the heat exchanger body. Secondly, by rotating the barrier frame on the abutment plate to make it horizontal and then supporting it again by the support components, the barrier frame in the horizontal position is lower than the barrier frame placed vertically, and the horizontally placed barrier frame can act as a "step" for workers to climb onto the barrier frame to work on the side components of the heat exchanger body, which is more convenient than carrying and climbing ladders.

[0019] It illustrates a wound tube heat exchanger for carbon black production according to one embodiment of the present invention, such as... Figure 1As shown, the device includes a heat exchanger body 2 mounted on a base plate 1, a protective frame 3, height adjustment components, a barrier frame 4, and support components. The protective frame 3 is fixedly mounted on the base plate 1, and the heat exchanger body 2 is located inside the protective frame 3, configured to protect the lower part of the heat exchanger body 2. Three height adjustment components are provided, all of which are mounted on the protective frame 3. Three barrier frames 4 are provided, each mounted on a height adjustment component via three abutment plates 5. The height adjustment components are configured to adjust the height of the barrier frames 4. The barrier frames 4 are hinged to the abutment plates 5 and can rotate to be perpendicular to the abutment plates 5 or to a horizontally laid-down position. Three support components are provided, all of which are located on the side of the protective frame 3, configured to support the barrier frames 4 when they are rotated to a vertical or perpendicular position.
[0020] When using the heat exchanger body 2, first rotate the three side guards 4 of the protective frame 3 onto the abutment plate 5 to a vertical position, as follows: Figure 4 and Figure 5 As shown, the vertically placed barrier frame 4 is then supported by a support assembly, which includes a support frame 12, a synchronizing rod 13, a support block 14, and an insert rod 15. Two support frames 12 are fixedly installed on the side of the protective frame 3, and a synchronizing rod 13 is slidably installed through each support frame 12. Two support blocks 14 are fixedly installed on the top of the barrier frame 4, and an insert rod 15 is slidably installed on the side of the synchronizing rod 13.
[0021] Specifically, when the barrier frame 4 is rotated to a vertical position, the operator holds the synchronizing rod 13 and moves it upward through the support frame 12. Since the side of the support block 14 has a support groove that matches the insertion rod 15, after moving it upward, the insertion rod 15 on the side of the synchronizing rod 13 is moved forward so that its side is inserted into the support groove, thereby supporting the vertically placed barrier frame 4.
[0022] like Figure 2 and Figure 3 As shown, the barrier frame 4 is then moved upward by the height adjustment component. The height adjustment component includes a mounting plate 6, an electric cylinder 7, railings 8, barrier posts 9, and a limiting component. The mounting plate 6 is fixedly installed on the protective frame 3. Two electric cylinders 7 are installed on the mounting plate 6. Railings 8 are fixedly installed on the output ends of the two electric cylinders 7. Several barrier posts 9 are fixedly installed between the railings 8, and abutment plates 5 are fixedly installed on the top of the barrier posts 9. The limiting component is set on the side of the protective frame 3. The limiting component includes a limiting rail 10 and a limiting rod 11. There are two limiting rails 10. Both limiting rails 10 are fixedly installed on the side of the protective frame 3. The limiting rods 11 are fixedly installed on the side of the two barrier posts 9, and the two limiting rods 11 are slidably installed on the side of the two limiting rails 10 respectively.
[0023] Specifically, when the electric cylinder 7 is activated, its output end drives the railing 8 upward. The barrier post 9 connected to the railing 8 moves upward simultaneously, thereby driving the abutment plate 5 and the barrier frame 4 upward. Because the top of the protective frame 3 has a through slot, and the railing 8 and the barrier post 9 both pass through the through slot of the protective frame 3, the railing 8 and the barrier post 9 can move upward through the through slot without being affected by the barrier frame 4. After the movement is completed, the barrier frame 4 protects the upper part of the heat exchanger body 2, the barrier post 9 and the railing 8 protect the middle part of the heat exchanger body 2, and the protective frame 3 protects the lower part of the heat exchanger body 2. At this time, the extended support frame 12 can prevent the staff from getting too close to the heat exchanger body 2 when carrying items. Because the edge of the support frame 12 is set to be arc-shaped, it avoids causing greater injury when bumping into the staff.
[0024] If subsequent work is required on the side components of the heat exchanger body 2, the lower parts of the heat exchanger body 2 are lower, so the workers can squat directly on the side of the heat exchanger body 2 to carry out maintenance. If work is required on the upper parts of the heat exchanger body 2, the electric cylinder 7 is activated again. The electric cylinder 7 drives the railing 8, the blocking post, the abutment plate 5, and the barrier frame 4 to move down, so that the railing 8 and the blocking post move down into the interior of the protective frame 3. At this time, the position of the barrier frame 4 moves down. Because several stabilizing seats 16 are fixedly installed on the mounting plate 6, and the several stabilizing seats 16 are located directly below several blocking posts 9, and the top of the stabilizing seat 16 has a slot that matches the bottom of the blocking post 9, the bottom of the blocking post 9 is inserted into the slot of the stabilizing seat 16 and stops. Then the workers can carry out work on the middle part or the upper part of the heat exchanger body 2.
[0025] like Figure 6 As shown, the insertion rod 15 can be moved back into the synchronization rod 13, and then the synchronization rod 13 can be moved down so that its bottom end contacts the top end of the base plate 1. When the bottom end of the synchronization rod 13 contacts the base plate 1, the top end of the synchronization rod 13 and the top end of the support frame 12 are at the same horizontal position. Then the barrier frame 4 is rotated to a horizontal position. When the bottom end of the barrier post 9 contacts the slot of the stabilizing seat 16, the bottom end of the barrier frame 4 contacts the top end of the support frame 12. At this time, the support frame 12 can support the barrier frame 4. If the staff needs to work on the upper parts, they can climb onto the barrier frame 4 and then work on the upper parts of the heat exchanger body 2.
[0026] Working principle: When using the heat exchanger body 2, firstly, rotate the three side guardrails 4 of the protective frame 3 to a vertical position on the abutment plate 5. Then, the operator holds the synchronizing rod 13 and moves it upward through the support frame 12. After moving upward, move the insert rod 15 on the side of the synchronizing rod 13 forward so that its side is inserted into the support groove, thereby supporting the vertically placed guardrail 4. Then, start the electric cylinder 7. The output end of the electric cylinder 7 drives the railing 8 to move upward. The guardrail 9 connected to the railing 8 moves upward synchronously, thereby driving the abutment plate 5 and the guardrail 4 to move upward. When the railing 8 and the guardrail 9 move upward, they can move upward through the through groove, so they will not be affected by the guardrail 4. After the movement is completed, the guardrail 4 protects the upper part of the heat exchanger body 2, the guardrail 9 and the railing 8 protect the middle part of the heat exchanger body 2, and the protective frame 3 protects the lower part of the heat exchanger body 2.
[0027] like Figure 7 As shown, because the protective frame 3 has a barrier 4 installed on three sides, the fourth side does not have a barrier 4 installed. The barrier is set to be openable, so the hot air furnace is installed on this side and connected to the heat exchanger body 2. The high-temperature flue gas generated in the hot air furnace enters the tube side of the heat exchanger body 2. Then the combustion fan draws in room temperature air and enters the shell side of the heat exchanger body 2. The hot flue gas flows in the tube and transfers heat to the tube wall. The tube wall then transfers heat to the cold air outside the tube. The flue gas temperature decreases and the air temperature increases. The hot air heated to a certain temperature is sent back to the hot air furnace as combustion air. After the temperature of the flue gas after heat exchange drops to the specified temperature, it is drawn away and discharged by the induced draft fan.
[0028] After the work is completed, if it is necessary to observe or replace the components on the side of the heat exchanger body 2, the electric cylinder 7 is activated again. The electric cylinder 7 drives the railing 8, the blocking post, the abutment plate 5, and the barrier frame 4 to move down, so that the railing 8 and the blocking post move down into the interior of the protective frame 3. At this time, the position of the barrier frame 4 moves down, causing the bottom end of the barrier post 9 to be inserted into the slot of the stabilizing seat 16 and stop. Then the worker can work on the middle part or the upper part of the heat exchanger body 2. Then the insertion rod 15 can be moved back into the synchronous rod 13, and then the synchronous rod 13 is moved down so that its bottom end contacts the top of the base plate 1. The barrier frame 4 is rotated to a horizontal position. At this time, the support frame 12 can support the barrier frame 4. If the worker needs to work on the upper parts, he can climb onto the barrier frame 4 and then work on the upper parts of the heat exchanger body 2.
[0029] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and not to limit them. Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of the present invention without departing from the spirit and scope of the technical solutions of the present invention, and all such modifications or substitutions should be covered within the scope of protection of the claims of the present invention.
