Description

Technical Field

[0001] The invention relates to the technical field of electrostatic precipitators, in particular to a ash conveying pipeline concentration measuring device for electrostatic precipitator optimization. Background Art

[0002] In the electrostatic precipitator process, accurate measurement of ash concentration in the ash conveying pipeline is crucial to 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, vibration frequency, etc., can be adjusted in time to ensure the best dust removal effect. At the same time, reasonable concentration measurement can also effectively prevent clogging of the ash conveying pipeline, extend the service life of the equipment and reduce maintenance costs.

[0003] Electrostatic precipitator equipment mainly achieves dust removal through corona discharge. Therefore, during the process of discharge dust removal, the surface of dust particles will be charged with static electricity. When the dust generated in the electrostatic precipitator process is transported through an ash conveying pipeline, the dust particles carry static electricity on their surfaces. Therefore, during the transportation process, they are easy to aggregate with each other and form agglomerates. When the dust agglomerates due to static electricity, its equivalent particle size will increase. Taking the light scattering method as an example, according to the light scattering theory, the larger the particle size, the stronger the scattered light intensity. After the dust agglomerates, the change in particle size will cause the measured scattered light intensity to increase, making the dust concentration calculated by the measuring instrument higher than the actual single particle dust concentration. Because these measurement methods are usually calibrated based on the optical or physical properties of single particles, agglomerates The agglomerated dust changes the original particle size-concentration relationship, thus causing measurement errors. At the same time, the size and number of dust clusters caused by electrostatic agglomeration may be uneven and unstable in the pipeline. When measurements are taken at different times or locations, the distribution and state of dust clusters are different, which will deteriorate the repeatability of the measurement results. For example, the dust concentration measured at a certain moment may be high because it passes through an area with more dust agglomerations. The next measurement may be low due to the redistribution of dust clusters in the pipeline and the reduction of dust clusters at the measurement position. This change makes it difficult to accurately assess the actual dust concentration in the pipeline, thereby affecting the accuracy of the dust concentration measurement in the ash conveying pipeline. For this reason, we propose an ash conveying pipeline concentration measurement device for electrostatic precipitator optimization. Summary of the invention

[0051] It should be noted here that the guide component is provided to provide guidance and limiting functions for the movement of the vibration rod 902 .

[0052] Working principle: When the dust concentration in the ash conveying pipeline body 101 is detected during the electrostatic precipitator process, the detection tube 103 is first connected to the two opposite ash conveying pipeline bodies 101 using the flange 104, and then the dust concentration measuring instrument 102 is connected and fixed to the ash conveying pipeline 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 pipeline body 101 by starting the exhaust fan at one end of the ash conveying pipeline body 101;

[0053] When dust flows in the ash conveying pipeline body 101, due to the static electricity on the dust surface, the dust will form a mass due to mutual adsorption. When the massed dust flows into the detection tube 103, the motor 506 is started to drive the first bevel gear 502 on the side wall of the driving rod 501 to rotate, and then the third rotating rod 504 is driven to rotate by the mutual meshing transmission action of the first bevel gear 502 and the second bevel gear 505. During the rotation of the third rotating rod 504, the connection action of the spline plate 603 and the spline groove 602 is used to drive the connecting rod 604 to rotate, further driving the first rotating rod 301 to rotate, and then driving the first crushing plates 303 on each first crushing rod 302 to rotate;

[0054] In the process of the first rotating rod 301 rotating, the gear ring 403 will be driven to rotate. In the process of the rotation of the gear ring 403, the meshing transmission action of the gear ring 403 and the rotating gear 402 will be used to drive the rotating gear 402 to rotate. In the process of the rotation of the rotating gear 402, the meshing transmission action of the rotating gear 402 and the tooth groove 404 on the mounting ring 304 will drive the mounting ring 304 to rotate. 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 making the first crushing plates 303 and the second crushing plates 306 rotate in opposite directions, so that the opposite rotation of the first crushing plates 303 and the second crushing plates 306 is used to shear the flowing massed dust, so that the massed dust is crushed under the shearing action of the first crushing plates 303 and the second crushing plates 306;

[0055] After the dust is crushed, the crushed dust will continue to move forward under the action of suction. When the crushed dust passes through the rectifying ring 201, the rectifying plates 202 comb the airflow, so that the airflow entering the detection tube 103 can be combed into a more regular flow state, which plays a role in 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, and then reducing the overall error caused by local concentration deviation, thereby further improving the accuracy of dust concentration measurement in the ash conveying pipeline body 101;

[0056] When the crushed and rectified dust flows through the detection area of ​​the dust concentration measuring instrument 102, when light is irradiated on the dust particles suspended in the airflow, light scattering will occur. Under certain conditions of the optical system and dust properties, the intensity of scattered light is proportional to the dust concentration. By measuring the intensity of scattered light, the dust concentration can be obtained through conversion.

[0057] When the driving rod 501 rotates, the shaking ring 701 will be driven to rotate synchronously, thereby driving each shaking plate 702 to rotate. When the shaking plate 702 is against the rectifying ring 201, the rectifying ring 201 will be driven to move away from the driving rod 501 under the pushing action of the shaking plate 702 and the guiding action of the telescopic component. When the shaking plate 702 passes over the rectifying ring 201, the rectifying ring 201 will be driven to move closer to the driving rod 501 under the elastic action of the telescopic component. Therefore, during the continuous rotation of the driving rod 501, the shaking plate 702 on the shaking ring 701 will be driven to reciprocate and resist the rectifying ring 201. Then, under the pushing action and the elastic action of the telescopic component, the rectifying ring 201 will perform reciprocating lateral movement. Therefore, the probability of dust adhering to the surface is reduced under the action of its own reciprocating lateral movement, thereby improving the accuracy of dust concentration measurement of the ash conveying pipeline body 101.

[0058] At the same time, during the rotation of each shaking plate 702, it will reciprocately resist against the vibration rod 902, and then under the interaction force and the guiding effect of the guide component and the effect of the reset component, the vibration rod 902 will be pushed to reciprocate against the inner wall of the detection tube 103, and then under the reciprocating vibration of the vibration rod 902, the inner wall of the detection tube 103 will vibrate, so that the dust adhered to the inner wall of the detection tube 103 due to static electricity is shaken off, thereby reducing the amount of dust adhered to the inner wall of the detection tube 103, thereby further reducing the amount of dust adhered to the inner wall of the detection tube 103 due to the impact of airflow, thereby reducing the measurement error of the dust concentration measuring instrument 102.
