Description
Electrostatic precipitator ash conveying pipeline concentration measurement device Technical Field
[0001] This invention relates to the field of electrostatic precipitator technology, specifically to a concentration measuring device for ash conveying pipelines used in the optimization of electrostatic precipitators. Background Technology
[0002] In the process of electrostatic precipitator, accurate measurement of ash concentration in the ash conveying pipeline is crucial for the efficient and stable operation of the system. By monitoring the ash concentration, the operating parameters of the electrostatic precipitator, such as electric field strength and rapping frequency, can be adjusted in a timely manner to ensure the best dust removal effect. At the same time, reasonable concentration measurement can also effectively prevent ash conveying pipeline blockage, extend equipment service life, and reduce maintenance costs.
[0003] Electrostatic precipitators primarily remove dust through corona discharge. During this process, dust particles become electrostatically charged. When transporting this dust through conveying pipes, the static electricity causes the particles to easily aggregate, forming clumps. As dust clumps due to electrostatic charge, their equivalent particle size increases. For example, according to light scattering theory, larger particles scatter more light. Dust agglomeration, due to the change in particle size, leads to an increase in the measured scattered light intensity, causing the measuring instrument to calculate a higher dust concentration than the actual concentration per particle. This is because these measurement methods are typically calibrated based on the optical or physical properties of individual particles. The agglomerated dust alters the original particle size-concentration relationship, leading to measurement errors. Furthermore, the size and number of dust clumps caused by electrostatic agglomeration may be uneven and unstable within the pipeline. Measurements taken at different times or locations will have poor repeatability due to variations in the distribution and state of the dust clumps. For example, the dust concentration measured at a certain moment may be higher because it passes through an area with a large amount of dust agglomeration, while the concentration may be lower in subsequent measurements due to the redistribution of dust clumps within the pipeline and a reduction in the number of dust clumps at the measurement location. This variation makes it difficult to accurately assess the true dust concentration within the pipeline, thus affecting the accuracy of dust concentration measurements in ash conveying pipelines. Therefore, we propose an optimized ash conveying pipeline concentration measurement device for electrostatic precipitators. Summary of the Invention

Detailed Implementation
[0029] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
[0030] Example 1
[0031] Please refer to Figures 1-10. The electrostatic precipitator optimization ash conveying pipeline concentration measuring device shown in the figure includes two opposing ash conveying pipeline bodies 101 and a dust concentration measuring instrument 102. The opposing ends of the two ash conveying pipeline bodies 101 are connected to a detection tube 103 through a flange 104. The dust concentration measuring instrument 102 is installed on the detection tube 103. It also includes a rectification mechanism set in the detection tube 103 for rectifying and dispersing the dust flowing through the detection area of the dust concentration measuring instrument 102, and a crushing mechanism set in the rectification mechanism for crushing the clump dust.
[0032] The rectifier mechanism includes a rectifier ring 201 disposed on the side of the detection tube 103 near the dust conveying direction. The rectifier ring 201 is connected to the detection tube 103 via a telescopic component. The rectifier ring 201 is fixedly connected to a plurality of rectifier plates 202 arranged in an alternating manner. The detection tube 103 is provided with a swaying component for reciprocating swaying of each rectifier plate 202.
[0033] It should be noted that: through the setting of the rectification mechanism and the crushing mechanism, and with the cooperation of the rotating component and the driving component, the clumps of dust adsorbed by electrostatic adsorption are crushed, and the crushed dust is rectified and uniformly dispersed. This makes the dust evenly distributed in the airflow, reduces the difference in dust concentration at different locations on the cross-section of the detection tube 103, and thus reduces the overall error caused by local concentration deviation, thereby further improving the accuracy of dust concentration measurement in the ash conveying pipe body 101.
[0034] Please refer to Figures 2, 8, and 9. The crushing mechanism shown includes a first rotating rod 301 rotatably connected to one of the rectifier plates 202. The first rotating rod 301 is concentrically arranged with the rectifier ring 201. The side wall of the first rotating rod 301 near the dust conveying direction is connected to a first crushing plate 303 via multiple first crushing rods 302. The side of the rectifier plate 202 near each of the first crushing plates 303 is rotatably connected to an mounting ring 304. The side wall of the mounting ring 304 is connected to a second crushing plate 306 via multiple second crushing rods 305. The rectifier plate 202 is provided with a rotating assembly for making the rotation directions of each of the first crushing plates 303 and each of the second crushing plates 306 opposite. The detection tube 103 is provided with a driving assembly for driving the first rotating rod 301.
[0035] It should be noted that, through the setting of the crushing mechanism, under the action of the rotating component, the first crushing plate 303 and the second crushing plate 306 rotate in opposite directions, thereby crushing the clump of dust under the shearing action of the first crushing plate 303 and the second crushing plate 306.
[0036] Please refer to Figures 2, 8 and 9. The rotating assembly shown includes a second rotating rod 401 rotatably connected to the side of the rectifier plate 202 near each of the first crushing plates 303. A rotating gear 402 is fixedly connected to the side wall of the second rotating rod 401. A gear ring 403 is fixedly connected to the side wall of the first rotating rod 301. The gear ring 403 and the rotating gear 402 are meshed with each other. Multiple tooth grooves 404 are opened on the inner wall of the mounting ring 304. Each tooth groove 404 is meshed with the rotating gear 402.
[0037] It should be noted that by setting the rotating component, the mounting ring 304 rotates in the opposite direction to the first rotating rod 301, which in turn causes the first crushing plates 303 and the second crushing plates 306 to rotate in the opposite direction. Thus, the opposite rotation of the first crushing plates 303 and the second crushing plates 306 is used to shear the flowing clump of dust.
[0038] Please refer to Figures 6 and 7. The driving assembly shown includes a driving rod 501 rotatably connected to the detection tube 103. The driving rod 501 is located on the side of the rectifier plate 202 away from each of the first crushing plates 303. A first bevel gear 502 is fixedly connected to the side wall of the driving rod 501. A first fixing plate 503 is fixedly connected to the inner wall of the detection tube 103. A third rotating rod 504 is rotatably connected to the first fixing plate 503. One end of the third rotating rod 504 near the rectifier plate 202 is connected to the first rotating rod 301 through a connecting assembly. A second bevel gear 505 is fixedly connected to the other end of the third rotating rod 504. The second bevel gear 505 and the first bevel gear 502 are meshed with each other. A motor 506 is provided on the side wall of the detection tube 103. The output end of the motor 506 is connected to the driving rod 501.
[0039] It should be noted here that the drive component is configured to drive the first rotating rod 301 and the swaying ring 701 to rotate.
[0040] Please refer to Figures 6 and 7. The connecting assembly shown includes a connecting cavity 601 opened in the third rotating rod 504. The inner wall of the connecting cavity 601 is provided with multiple spline grooves 602. Each spline groove 602 is slidably connected to a spline plate 603. A connecting rod 604 is fixedly connected to the side of the spline plate 603 near the rectifier plate 202. The other end of the connecting rod 604 is connected to the first rotating rod 301. A first spring 605 is sleeved on the side wall of the connecting rod 604 inside the connecting cavity 601. The two ends of the first spring 605 are respectively connected to the spline plate 603 and the inner wall of the connecting cavity 601.
[0041] It should be noted here that by setting the connecting components, the drive rod 501 and the first rotating rod 301 can remain connected during the reciprocating lateral movement of the rectifier ring 201.
[0042] Please refer to Figures 6 and 10. The swaying assembly shown in the figures includes two symmetrically arranged swaying rings 701 fixedly connected to the side wall of the drive rod 501. Multiple swaying plates 702 arranged in a ring array are fixedly connected to the side walls of the two swaying rings 701. Inclined surfaces 703 are provided on the two opposite side walls of each swaying plate 702.
[0043] It should be noted here that the shaking component is used to drive the rectifier ring 201 to move laterally in a reciprocating manner. This reciprocating lateral movement reduces the probability of dust adhering to the surface, thereby improving the accuracy of dust concentration measurement of the ash conveying pipe body 101.
[0044] Please refer to Figures 2 and 3. The telescopic assembly shown in the figures includes multiple second fixing plates 801 fixedly connected to the inner wall of the detection tube 103. Each second fixing plate 801 is located on the side of the rectifier ring 201 away from the swaying ring 701. Each second fixing plate 801 is fixedly connected to a telescopic tube 802 on the side near the rectifier ring 201. Each telescopic tube 802 is slidably connected to a telescopic rod 803. One end of each telescopic rod 803 is connected to the rectifier ring 201. The other end of each telescopic rod 803 is located inside the telescopic tube 802 and is fixedly connected to a telescopic plate 804. Each telescopic rod 803 is fitted with a second spring 805 on the inner side wall of the telescopic tube 802. Both ends of each second spring 805 are connected to the telescopic plate 804 and the inner wall of the telescopic tube 802, respectively.
[0045] It should be noted here that the telescopic component is used to guide and reset the movement of the rectifier ring 201.
[0046] Please refer to Figures 4 and 5. The detection tube 103 shown in the figures is equipped with a vibration assembly to reduce dust adhesion to the inner wall of the tube. The vibration assembly includes two symmetrically arranged U-shaped plates 901 fixedly connected to the inner wall of the detection tube 103. The two U-shaped plates 901 are connected to vibration rods 902 through a guide assembly. One end of the two vibration rods 902 near the inner wall of the detection tube 103 is provided with a rubber pad. The other end of the two vibration rods 902 is arranged opposite to the shaking ring 701. The two U-shaped plates 901 are provided with a reset assembly for resetting the vibration rods 902.
[0047] It should be noted that the vibration component causes the inner wall of the detection tube 103 to vibrate, thereby shaking off the dust adhering to the inner wall of the detection tube 103 due to electrostatic action. This reduces the amount of dust adhering to the inner wall of the detection tube 103, further reducing the amount of dust lifted by the airflow, and thus reducing the measurement error of the dust concentration measuring instrument 102.
[0048] Please refer to Figures 4 and 5. The reset assembly shown in the figures includes a reset ring 1001 fixedly connected to the side wall of the vibration rod 902. A third spring 1002 is sleeved on the side wall of the vibration rod 902. The two ends of the third spring 1002 are respectively connected to the reset ring 1001 and the side wall of the U-shaped plate 901.
[0049] It should be noted here that: by setting the reset component, when each shaking plate 702 is no longer in contact with the vibration rod 902, it is used to drive the vibration rod 902 to reset.
[0050] Please refer to Figures 4 and 5. The guide assembly shown in the figures includes a sliding hole opened in the U-shaped plate 901, a vibration rod 902 slidably connected to the sliding hole, a guide strip 1101 fixedly connected to the inner wall of the sliding hole, a guide groove 1102 opened on the side wall of the vibration rod 902, and the guide strip 1101 slidably connected to the guide groove 1102.
[0051] It should be noted here that the guide component is used to guide and limit the movement of the vibration rod 902.
[0052] Working principle: When detecting the dust concentration in the ash conveying pipe body 101 during the electrostatic precipitator process, the detection tube 103 is first connected to the two opposite ash conveying pipe bodies 101 using the flange 104. Then, the dust concentration measuring instrument 102 is connected and fixed to the ash conveying pipe body 101. After the dust concentration measuring instrument 102 is connected and fixed, the dust generated by the electrostatic precipitator can be sucked into the ash conveying pipe body 101 by starting the exhaust fan at one end of the ash conveying pipe body 101.
[0053] When dust flows inside the ash conveying pipe body 101, the dust surface is statically charged, causing the dust to form clumps due to mutual adsorption. When the clumps of dust flow into the detection tube 103, the motor 506 is started, which drives the first bevel gear 502 on the side wall of the drive rod 501 to rotate. Then, through the meshing transmission of the first bevel gear 502 and the second bevel gear 505, the third rotating rod 504 is driven to rotate. During the rotation of the third rotating rod 504, the connecting rod 604 is driven to rotate through the connection between the spline plate 603 and the spline groove 602, which in turn drives the first rotating rod 301 to rotate, and then drives the first crushing plate 303 on each of the first crushing rods 302 to rotate.
[0054] Furthermore, during the rotation of the first rotating rod 301, the gear ring 403 will be driven to rotate. During the rotation of the gear ring 403, the gear ring 403 will be driven to rotate under the meshing transmission action of the rotating gear 402. During the rotation of the rotating gear 402, the rotating gear 402 will be driven to rotate under the meshing transmission action of the tooth groove 404 on the mounting ring 304. Under the transition action of the rotating gear 402, the mounting ring 304 will be driven to rotate in the opposite direction to the first rotating rod 301, thereby causing the first crushing plates 303 and the second crushing plates 306 to rotate in the opposite direction. Thus, the opposite rotation of the first crushing plates 303 and the second crushing plates 306 forms shear on the flowing clump of dust, thereby crushing the clump of dust under the shearing action of the first crushing plates 303 and the second crushing plates 306.
[0055] After the agglomerated dust is broken up, the dust will continue to move forward under the action of suction. When the broken dust passes through the rectifier ring 201, the airflow entering the detection tube 103 can be sorted into a more regular flow state by the sorting effect of each rectifier plate 202, which plays the role of rectification and uniform dispersion, so that the dust is evenly distributed in the airflow, reducing the difference in dust concentration at different positions on the cross-section of the detection tube 103, thereby reducing the overall error caused by local concentration deviation, and further improving the accuracy of dust concentration measurement in the ash conveying pipe body 101.
[0056] When the dust that has been crushed and rectified flows through the detection area of the dust concentration measuring instrument 102, when light shines on the dust particles suspended in the airflow, light scattering will occur. Under certain conditions of optical system and dust properties, the intensity of scattered light is proportional to the dust concentration. By measuring the intensity of scattered light and converting it, the dust concentration can be obtained.
[0057] Furthermore, during the rotation of the drive rod 501, the swaying ring 701 will rotate synchronously, thereby causing each swaying plate 702 to rotate. When the swaying plate 702 abuts against the rectifier ring 201, under the pushing action of the swaying plate 702 and the guiding action of the telescopic component, the rectifier ring 201 will move away from the drive rod 501. When the swaying plate 702 passes the rectifier ring 201, under the elastic action of the telescopic component, the rectifier ring 201 will move closer to the drive rod 501. Thus, during the continuous rotation of the drive rod 501, the swaying plate 702 on the swaying ring 701 will reciprocate against the rectifier ring 201. Under the pushing action and the elastic action of the telescopic component, the rectifier ring 201 will reciprocate laterally. Through its own reciprocating lateral movement, the probability of dust adhering to the surface is reduced, thereby improving the accuracy of dust concentration measurement of the ash conveying pipeline body 101.
[0058] Simultaneously, during the rotation of each vibrating plate 702, it will reciprocate against the vibrating rod 902. Under the interaction force, the guiding effect of the guide component, and the action of the reset component, the vibrating rod 902 will be pushed to reciprocate against the inner wall of the detection tube 103. Under the reciprocating vibration of the vibrating rod 902, the inner wall of the detection tube 103 will vibrate, thereby shaking off the dust that adheres to the inner wall of the detection tube 103 due to electrostatic effect. This reduces the amount of dust adhering to the inner wall of the detection tube 103, further reducing the amount of dust lifted from the inner wall of the detection tube 103 due to the impact of airflow, and thus reducing the measurement error of the dust concentration measuring instrument 102.
