Description

Technical Field

[0001] This utility model relates to the field of waste heat recovery equipment technology, and more specifically, to a waste heat recovery device for flue gas from a gas generator set. Background Technology

[0002] During operation, gas-fired power generation units emit large amounts of high-temperature flue gas, which contains a significant amount of recoverable waste heat. Waste heat boilers are commonly used equipment for recovering heat energy from high-temperature flue gas. Their core function is to convert the waste heat in the flue gas into steam or hot water through heat exchange, achieving cascaded utilization of energy and thus improving the overall energy efficiency of the power generation unit, reducing energy consumption and carbon emissions. The gas waste heat boiler receives the high-temperature flue gas discharged from the gas-fired power generation unit through pipelines. The flue gas flows through the heat transfer heat exchange components of the boiler. During this process, the heat energy in the flue gas is transferred to the medium such as water in the heat exchange components through heat conduction, causing the water to gradually heat up and vaporize, eventually generating saturated steam or superheated steam. After releasing heat, the temperature of the flue gas is significantly reduced. After purification treatment, it meets emission standards. The generated steam can be directly used for power generation, industrial production, or heating, achieving efficient recovery and reuse of waste heat from the flue gas. Since soot particles mixed in the flue gas will adhere to the surface of the heat exchange components, it is necessary to remove the soot particles.

[0003] In related technologies, during the use of waste heat recovery devices, workers typically use brushes or scrapers to periodically remove soot particles from the surface of the heat exchange components before they can be used.

[0004] However, in the current use of waste heat recovery devices, when removing dust particles from the surface of heat exchange components through contact friction between the brush and the scraper, only one or a single set of heat exchange components can be removed at a time. This makes the dust particle removal operation of the waste heat recovery device cumbersome and inconvenient, affecting the ease of dust particle removal operation. Utility Model Content

[0029] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0030] Reference Figures 1-4 This utility model provides a technical solution: a waste heat recovery device for flue gas from a gas generator set, including a waste heat recovery box 1 and a soot removal mechanism. A heat pipe 2 is installed at the bottom inside the waste heat recovery box 1, and connectors 3 are installed on both sides of the waste heat recovery box 1. When soot particles need to be removed from the heat pipe 2, the device can provide the user with a brushing medium for removing soot particles from multiple heat pipes 2, so that the user can brush away the soot particles attached to the surface of the heat pipe 2. This avoids the situation where it is difficult to remove soot particles from multiple heat pipes 2, thus improving the convenience of soot particle removal operation of the heat pipe 2.

[0031] Reference Figures 1-4 In a preferred embodiment, the soot removal mechanism includes a movable frame 4, which is movably connected to the bottom of the inner wall of the waste heat recovery box 1. Brush rods 5 are movably connected inside the movable frame 4. Support columns 6 are fixedly connected to both sides of the bottom of the movable frame 4. A scraper 7 is fixedly connected to the rear side of the bottom of the movable frame 4. A removal support mechanism is located on both sides of the top of the movable frame 4. Multiple brush rods 5 move synchronously through the movable frame 4. Since the brush rods 5 have a double-sided bristle design and the bristles are in contact with each other, as the brush rods 5 move up and down inside the waste heat recovery box 1 following the movable frame 4, the bristles on both sides of the vertical rods perform friction brushing to remove the soot particles attached to the surface of the heat pipe 2, causing the soot particles to come into contact with the heat. Separating tube 2 allows for the removal of soot particles from heat pipe 2. The removal support mechanism includes a support port 8, a support groove 9, and a support block 10. The support port 8 is located on both sides of the top of the movable frame 4, and the support groove 9 is located on the inner side of the top of the inner wall of the support port 8. The support block 10 is movably connected inside the support groove 9, and the inner side of the support block 10 is fixedly connected to the outer side of the brush rod 5. This provides support for the connection between the vertical rod and the movable frame 4, facilitating the installation and connection of the brush rod 5 with the movable frame 4. Simultaneously, it stabilizes the position of the brush rod 5, preventing difficulties in installation and connection with the movable frame 4 or positional deviation during use. Therefore, it improves the connection stability between the brush rod 5 and the movable frame 4.

[0032] Reference Figures 2-4In a preferred embodiment, a stabilizing rod 11 is movably connected inside the support opening 8. The bottom of the stabilizing rod 11 has a stabilizing groove 12 that communicates with the support groove 9. This can stabilize the installation between the support block 10 and the support groove 9, preventing the support block 10 from detaching from the support groove 9 during operation, thus improving the working stability of the support block 10. Insertion holes 13 are provided on both sides of the top of the stabilizing rod 11. Insertion posts 14 are movably connected inside the insertion holes 13. The bottom of the insertion posts 14 is fixedly connected to the bottom of the inner wall of the support opening 8. This can prevent the stabilizing rod 11 from shifting during installation and insertion, thus improving the connection stability between the mounting rod and the support opening 8.

[0033] Reference Figures 2-4 In a preferred embodiment, a screw groove 15 is provided on the top of the insert post 14, and a bolt 16 located on the top of the stabilizer rod 11 is connected to the screw groove 15 internally. The screw groove 15 can be used to fasten the stabilizer rod 11 and the support port 8 through the insert post 14, so as to avoid the situation where the stabilizer rod 11 is difficult to fix during operation. Therefore, the fixing convenience of the stabilizer rod 11 is improved. Lifting bars 17 are installed on the front and rear sides of both sides of the inner wall of the waste heat recovery box 1. The top of the movable frame 4 is provided with a lifting port 18 located at the bottom of the lifting bar 17, which can guide the lifting connection between the movable frame 4 and the waste heat recovery box 1, so as to avoid the situation where the movable frame 4 is difficult to maintain its moving position during use. Therefore, the operation convenience of the movable frame 4 is improved.

[0034] Reference Figures 2-4 In a preferred embodiment, screw holes 19 are provided at the top and bottom of the inner side of the lifting bar 17. Screws 20 that are threaded to the waste heat recovery box 1 are movably connected inside the screw holes 19. The screws 20 can be threaded to the lifting bar 17 and the waste heat recovery box 1 to ensure that the lifting bar 17 does not separate from the waste heat recovery box 1 during operation. This improves the guiding stability of the lifting bar 17. Both sides of the bottom front side of the waste heat recovery box 1 are movably connected to the operating frame 21. The rear side of the operating frame 21 is fixedly connected to the front side of the movable frame 4, which can provide the user with the operating medium to move the movable frame 4. This improves the ease of operation of the movable frame 4.

[0035] Specifically, the working process or working principle of this waste heat recovery device for gas generator sets is as follows: During use, the door panels on both sides of the front of the waste heat recovery box 1 are flipped open. Then, the movable frame 4 is placed inside the bottom of the waste heat recovery box 1 by holding the operating frame 21. The movable frame 4 is pushed backward until its rear side contacts the rear side of the inner wall of the waste heat recovery box 1 and cannot be pushed further, so that the brush rod 5 is located at the bottom of the heat pipe 2, preparing for the subsequent cleaning of soot particles on the surface of the heat pipe 2 by the brush rod 5. At this time, the lifting port 18 moves with the movable frame 4. As the movable frame 4 moves into position, the lifting port... 18 also moves to the bottom of the lifting bar 17 to prepare for the subsequent lifting and guiding of the movable frame 4 and the waste heat recovery box 1. During this process, the stabilizing rod 11, together with the stabilizing groove 12, supports and stabilizes the brush rod 5 and the movable frame 4 through the support block 10 and the support groove 9. At the same time, the insert post 14, together with the insert hole 13, connects and tightens the stabilizing rod 11 and the support port 8 through the screw groove 15 and the bolt, ensuring the connection stability between the stabilizing rod 11 and the support port 8. After the movable frame 4 moves the brush rod 5 into place inside the waste heat recovery box 1, the handheld operating frame 21 applies pressure to the movable frame 4 into the waste heat recovery box 1. The lifting and lowering thrust of the movable frame 4 causes the brush rod 5 to move up and down inside the waste heat recovery box 1 and outside the heat pipe 2. This causes the bristles on both sides of the brush rod 5 to rub and brush away the soot particles attached to the surface of the heat pipe 2, separating the soot particles from the heat pipe 2. At this time, the lifting bar 17 moves into the lifting port 18 along with the movable frame 4, guiding the movable frame 4 and the waste heat recovery box 1 during the lifting process to prevent deviation. Simultaneously, the screw 20, in conjunction with the screw thread 19, tightens the threads between the lifting bar 17 and the waste heat recovery box 1. When the movable frame 4 drives the brush rod 5 to move up and down, it... After the soot particles adhering to the surface of heat pipe 2 are removed by friction brushing, the movable frame 4 is placed at the bottom of the inner wall of the waste heat recovery box 1. At this time, the support column 6 supports the movable frame 4 and the waste heat recovery box 1, so that the bottom of the scraper 7 contacts the bottom of the inner wall of the waste heat recovery box 1. Then, the movable frame 4 is pulled forward by the hand operating frame 21 and moved out of the waste heat recovery box 1. At this time, the scraper 7 moves forward with the movable frame 4 and scrapes the soot particles that have fallen to the bottom of the inner wall of the waste heat recovery box 1 by friction brushing when the brush rod 5 is working. As the movable frame 4 moves out of the waste heat recovery box 1, the scraper 7 scrapes the soot particles out of the waste heat recovery box 1.

[0036] It should be noted that the waste heat recovery box 1, heat pipe 2 and connector 3 are all existing devices or equipment, or devices or equipment that can be implemented with existing technology. Their power supply, specific composition and principle are clear to those skilled in the art, so they will not be described in detail.
