Description

Technical Field

[0002] Flue gas waste heat utilization systems capture and utilize the heat energy in flue gases generated during industrial processes through various technical means, including flue gas heat exchangers and waste heat boilers. These technologies have been widely adopted in industry, effectively improving energy efficiency and reducing energy consumption and carbon emissions. However, simple flue gas waste heat utilization only addresses energy recovery, but does not directly address flue gas emissions such as solid particulate matter and dust. If these solid particulates and dust are released directly into the atmosphere without treatment, they can not only pollute the surrounding environment but also pose health and safety risks. This is particularly true in areas of intensive industrial production. Purifying flue gas before discharge can reduce its impact on the environment and the human body.

[0003] However, most existing smoke exhaust purification structures use filters to filter solid particles in the flue gas. However, after long-term use, the particles are easily attached to the surface of the filter, causing the filter to be blocked, thereby reducing the filtering capacity of the filter. For this reason, those skilled in the art have proposed a smoke exhaust purification structure based on a flue gas waste heat utilization system to solve the above problem. Utility Model Content

Obviously, the embodiments described are only 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 ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0029] Reference Figure 1 、 Figure 2 and Figure 3, the utility model provides an embodiment: a smoke exhaust purification structure based on a flue gas waste heat utilization system, including an installation box 1, the outside of the installation box 1 is fixedly connected to a fixed block 9, the outside of the fixed block 9 is fixedly connected to an air intake pipe 11, the outside of the air intake pipe 11 is fixedly connected to a cooler 12, the outside of the fixed block 9 is fixedly connected to a motor 2 10, the inner wall of the fixed block 9 is rotatably connected to an eccentric wheel 18, the outer eccentric part of the eccentric wheel 18 is rotatably connected to a moving part 19, the outer side of the moving part 19 is rotatably connected to a brush 21, the inner wall of the fixed block 9 is fixedly connected to a filter screen 2 17, and an angle adjustment component is installed on the top of the installation box 1, which is used to adjust the angle of the exhaust pipe 5; the inner wall of the fixed block 9 is slidably connected to a limiting part 20, and a groove is provided on the outside of the limiting part 20, and the outer side of the moving part 19 is slidably connected to the inner wall of the groove; the side of the brush 21 away from the moving part 19 is slidably connected to the outer side of the filter screen 2 17, and the brush 21 is made of flexible material.

[0030] Furthermore, the flue gas is first transported into the interior of the fixed block 9 through the air intake pipe 11. During the transportation process, the flue gas is cooled by the cooler 12 so that the flue gas temperature drops to a safe range, and the solid particles and dust in the flue gas are filtered by the filter screen 17. At this time, the motor 10 is started, and the output end of the motor 10 drives the eccentric wheel 18 to rotate along the inner wall of the fixed block 9, thereby driving the movable part 19 to rotate at the same time. At the same time, the movable part 19 drives the brush 21 to move left and right along the outside of the limiting part 20, and the surface of the filter screen 17 is cleaned by the brush 21, effectively preventing the filter holes of the filter screen 17 from being blocked; the brush 21 is limited by the limiting part 20, so that the brush 21 moves left and right to clean the filter screen 17, preventing the filter screen 17 from being blocked and reducing the filtration efficiency; the brush 21 is made of flexible material, which can effectively prevent the surface of the filter screen 17 from being scratched and delaying the service life of the filter screen 17.

[0031] Reference Figure 1 and Figure 2 The angle adjustment component includes a support block 2, the bottom of the support block 2 is fixedly connected to the top of the installation box 1, the top of the support block 2 is fixedly connected to a motor 3, the top of the installation box 1 is rotatably connected to a gear 4, a connecting groove 8 is provided on the top of the installation box 1, the top of the connecting groove 8 is slidably connected to a rack plate 7, the top of the installation box 1 is rotatably connected to a gear 2 6, the outer side of the gear 2 6 is fixedly connected to an exhaust pipe 5, and the bottom of the exhaust pipe 5 is fixedly connected to a connecting block 13.

[0032] Furthermore, in addition, the motor 13 is started, and the output end of the motor 13 drives the gear 14 to rotate. At the same time, the gear 14 drives the rack plate 7 to slide through engagement, and then under the meshing action of the rack plate 7, the gear 2 6 rotates, and then drives the exhaust pipe 5 to rotate to a suitable angle. By rotating the exhaust pipe 5, the smoke exhaust becomes smoother.

[0033] Reference Figure 1 and Figure 2 The outside of gear 1 4 is meshed with the outside of the rack plate 7 at the corresponding position, and the outside of the rack plate 7 is meshed with the outside of gear 2 6 at the corresponding position; a sealing groove is provided on the inner top wall of the installation box 1, and a sealing ring is fixedly connected to the top of the connecting block 13; a guide member 14 is fixedly connected to the inner wall of the installation box 1, and the longitudinal section of the guide member 14 is trapezoidal; an activated carbon filter 16 is fixedly connected to the inner wall of the installation box 1, and a heat exchanger 15 is fixedly connected to the inner wall of the installation box 1.

[0034] Furthermore, gear 1 4 drives the rack plate 7 to slide through meshing, and then drives gear 2 6 to rotate, thereby adjusting the smoke exhaust direction so that the smoke exhaust follows the wind direction; the sealing ring fits the sealing groove to effectively prevent smoke leakage when the exhaust pipe 5 rotates, thereby ensuring the tightness of the device; due to the smoke's own movement trajectory from bottom to top, and then through the guiding effect of the guide member 14, the smoke is gathered to the position of the exhaust pipe 5, thereby improving the smoke exhaust efficiency; the activated carbon filter 16 adsorbs harmful substances in the smoke, and further purifies the smoke. The filtered smoke still has heat, and the smoke is in contact with the heat exchanger 15, so that the heat in the smoke is transferred, and then the water inside the heat exchanger 15 is heated, thereby improving the utilization rate of the waste heat of the smoke.

[0035] Working principle: First, the flue gas is transported through the air inlet pipe 11, and the flue gas is cooled by the cooler 12. Then the flue gas enters the interior of the fixed block 9, and the solid particles and dust in the flue gas are filtered by the filter screen 17. The motor 10 is started, and the output end of the motor 10 drives the eccentric wheel 18 to rotate, and then drives the moving part 19 to rotate. At the same time, the moving part 19 drives the brush 21 to move left and right along the outside of the limit part 20. The surface of the filter screen 17 is cleaned by the brush 21, and the surface accumulation of the filter screen 17 is effectively removed, and the original filtering efficiency of the filter screen 17 is restored.

[0036] In addition, when motor 13 is started, the output end of motor 13 drives gear 14 to rotate, and gear 14 drives rack plate 7 to slide along the inner wall of connecting groove 8. Then, under the meshing action of rack plate 7, gear 2 6 drives exhaust pipe 5 to rotate. By rotating exhaust pipe 5, the exhaust direction of smoke is adapted to the wind direction, preventing strong wind from flowing back into the device and causing smoke backflow.
