地下金属矿山袋式除尘器捕尘材料研究现状及展望

Research status and prospects of dust collection materials for bag filters in underground metal mines

袋式除尘器作为一种高效且适应性强的除尘设备而被广泛应用,但在地下金属矿山的实际应用中容易出现滤袋黏结,接口处易破坏及滤灰、清灰效果不佳等问题,且存在整体设备体积大、不易移动的弊端。研究重点从地下金属矿山环境特性,捕尘材料及其改良技术与评价标准进行阐述。结果表明:地下金属矿山作业环境及粉尘特性与其他工业场所差异较大;捕尘材料未来的主要研究方向为利用还原氧化石墨烯喷涂技术对PPS(聚苯硫醚)捕尘材料进行改良,以及研发适用于地下金属矿山的方法简单、成本低的新型可重复的袋式捕尘材料;进一步完善捕尘材料的综合性能及实际应用中的评价标准。研究为解决金属矿山粉尘问题提供了更为切实可行的方案。

Bag filters,known for their high efficiency and adaptability,are widely used.However,practical challenges such as filter bag adhesion,damage at the interfaces,suboptimal dust collection,and cleaning performance,along with the bulky nature of the equipment hindering their mobility in underground metal mines.This study reviews key aspects such as the environmental characteristics of underground metal mines,dust collection materials,improvement techniques,and evaluation standards.Findings suggest that the working environment and dust properties in underground metal mines significantly differ from those in other industrial settings.Future research on dust collection materials should focus on the application of reduced graphene oxide spraying technology to improve PPS(polyphenylene sulfide)materials and the development of new,easily prepared,cost-effective,and reusable bag filter materials tailored for underground metal mines.The overall performance is further enhanced and the evaluation standards for dust collection materials are refined.The study will offer practical solutions for dust control in metal mines.
