摘要

摘要: 针对当前工业领域日益严峻的粉尘污染治理挑战，研究创新性地提出一种磁场强化耦合丝网静电过滤式除尘器。该技术通过引入外部磁场对传统静电除尘过程进行物理强化，系统对比分析了磁场介入前后放电特性及除尘效率的变化规律。深入探究金属丝网结构参数对除尘性能的作用效果，重点考察3个核心结构因素：金属丝网孔径（1，2，3 mm）、丝网堆叠层数（1层、2层、3层）以及丝网表面复合过滤材料（聚乙烯过滤网、锦纶网）对粉尘脱除效率的作用效果。同时，系统测试了风速（1~5 m/s）、进气方向（正/反方向）及粉尘种类（飞灰粉尘、燃煤粉尘、水泥灰）对除尘效率的影响规律。研究结果表明，优化后的磁场-丝网耦合结构可显著增强微细粉尘的荷电与捕集效率，为工业烟气高效除尘提供了一种可行的技术方案。

Abstract: In response to the increasingly severe dust pollution control challenges in the current industrial field， this paper innovatively proposed a electrostatic dust collector with magnetic enhancement and wire mesh filtration. By introducing an external magnetic field， this technology physically enhances the traditional electrostatic dedusting process. A systematic comparative analysis was conducted on the variation patterns of discharge characteristics and dust removal efficiency before and after the magnetic field intervention. The experiments investigated the impact of wire mesh structural parameters on dust removal performance， focusing on three core factors： pore sizes of the metal wire mesh （1， 2， 3 mm）， number of stacked wire mesh layers（1， 2， 3）， and the type of composite filtration material coated on the wire mesh surface （polyethylene filter mesh， polyamide mesh）. Concurrently， the effects of airflow velocity （1 to 5 m/s）， inlet flow direction （forward/reverse direction）， and dust type （fly ash， coal combustion dust， cement ash） on the removal efficiency were systematically tested. The experimental results showed that the optimized magnetic field-wire mesh coupling structure could significantly enhance the charging and capture efficiency of fine dust， providing a feasible technical solution for efficient industrial flue gas dedusting.
