Abstract
Wet Filter Dust Collectors (WFDC) are commonly used in the mining industry for dust control. However, when filtering high concentration dust-laden air streams, the filter of WFDC is easily clogged. To solve the problem, this paper proposes a multi-stage filtration strategy based on Metal-based filter screens (MBFS) and conducts experimental. The results indicate that when the inlet dust concentration was 400 mg/m³ , using a dual-layer MBFS with filtration precisions of 40 and 60 mesh and an installation distance of 0 mm, the WFDC achieves the minimum pressure drop of 450.09 Pa and dust emission concentration of 2.89 mg/m³ . Additionally, when the inlet dust concentration increases, the WFDC can operate stably for a long time, and no clogging was observed for the filter. The multi-stage filtration strategy effectively solves the filter clogging problem. The results provide theoretical guidance for the design and application of WFDCs.
