折叠滤筒结构参数的试验验证及工业应用优化策略

Experimental verification of structural parameters and optimization strategies for industrial applications of pleated filter cartridges

摘要

针对工业除尘中折叠滤筒因结构参数不当导致的运行阻力大、清灰难等痛点,探究了褶间距与褶深比值对滤筒过滤性能及剥灰率的影响机制。研究结果表明,剥灰率随褶间距与褶深比值增大而提升;滤筒褶间距与褶深的最优配比区间为0.38~0.46。工程应用验证显示,在山西某炼钢厂改造项目中,采用优化参数后的滤筒可使系统运行阻力和粉尘浓度明显下降,且滤筒使用寿命显著延长。研究为折叠滤筒的精密制造与工业除尘系统的节能降耗提供了量化依据与实践指导。

Abstract

To address high operating resistance and poor cleaning efficiency caused by inappropriate parameter configuration of pleated filter cartridges in industrial dust removal, the impact of the pleat spacing-to-depth ratio on filtration performance and dust removal efficiency was investigated. The results showed that the dust removal efficiency increased with an increased pleat spacing-to-depth ratio; the optimal range for the pleat spacing-to-pleat-depth ratio was 0.38-0.46. Engineering application validation demonstrated that, in a steel plant renovation project in Shanxi, the use of optimized filter cartridges could significantly reduce system operating resistance and dust concentration, and extend the service life of the filter cartridges. The study provides a quantitative basis and practical guidance for the precision manufacturing of pleated filter cartridges and energy conservation of industrial dust removal systems.
