摘要

摘要为了进一步提高细颗粒的捕集效果，提出了一种改进型静电旋风除尘器(ECP)。揭示了球形圆柱ECP的电磁除尘机理，讨论了有无磁约束作用时烟气速度对细颗粒除尘效果的影响。结果表明:随着烟气速度的变化，细颗粒整体效率曲线呈“驼峰”型，磁感应强度的增大促使驼峰向低烟气速度区移动;增大磁感应强度可以改善球形圆柱磁约束ECP的俘获性能，但随着相同磁感应强度的增大，改善效果逐渐减弱。关键词:项目资助:国家自然科学基金项目(12172228,11572187)，上海市自然科学基金项目(22ZR1444400)，上海市科委基金项目(22dz1206005, 22dz1204202)，上海市可再生能源智能运维专业技术服务平台(22DZ2291800)。披露声明作者未报告潜在的利益冲突。数据可用性声明由于本研究中所问问题的敏感性，原始数据将保密，不会被共享。基金资助:国家自然科学基金项目(12172228,11572187)、上海市自然科学基金项目(22ZR1444400)、上海市科委基金项目(22dz1206005, 22dz1204202)、上海市可再生能源智能运维专业技术服务平台项目(22DZ2291800)。

Dust-removal performance of an improved spherical cylindrical ECP under magnetic confinement effect

AbstractIn order to further improve the trapping effect of fine particles, an improved electrostatic cyclone precipitator (ECP) was proposed. The electromagnetic dust-removal mechanism of spherical cylindrical ECP was revealed, and the influences of flue gas velocity on the dust-removal effect of fine particles with and without magnetic confinement effect were discussed. The results show that the overall efficiency curve of fine particles shows a ' hump ' type with the change of flue gas velocity, and the increase of magnetic induction intensity promotes the hump to move to the low flue gas velocity area. Increasing magnetic induction intensity can improve the trapping performance of spherical cylindrical magnetically constrained ECP, and the improvement effect weakens gradually when the same amplitude increases.Keywords: Spherical cylindrical ECPmagnetic confinement effectfine particlesdust-removal performancehump AcknowledgmentsThis work is sponsored by National Natural Science Foundation of China (12172228, 11572187), Natural Science Foundation of Shanghai (22ZR1444400), the Program of Foundation of Science and Technology Commission of Shanghai Municipality (22dz1206005, 22dz1204202), and Shanghai Professional Technical Service Platform for Intelligent Operation and Maintenance of Renewable Energy (22DZ2291800).Disclosure statementNo potential conflict of interest was reported by the author(s).Data availability statementDue to the sensitive nature of the questions asked in this study, raw data would remain confidential and would not be shared.Additional informationFundingThis work is sponsored by National Natural Science Foundation of China (12172228, 11572187), Natural Science Foundation of Shanghai (22ZR1444400), the Program of Foundation of Science and Technology Commission of Shanghai Municipality (22dz1206005, 22dz1204202), and Shanghai Professional Technical Service Platform for Intelligent Operation and Maintenance of Renewable Energy (22DZ2291800).
