Dry Sand Erosion Damage Characteristic of Fibers Induced by Solid Particle Impact

摘要

Abstract Bag filters made of fibrous components are widely used for cleaning exhaust gas. Filter damage caused by dust collection results from the erosion of the filter during particle collision. We developed an experimental and evaluation method to investigate the erosion characteristics of fibers. Using the suggested kinetic energy of impact, we evaluated the erosion wear characteristics of fibers under different experimental conditions. The results demonstrated that fiber erosion wear depended on the kinetic energy of impact. The level of erosion wear changes based on the material characteristics (brittle or ductile) and on the impact angle of solid particles. In addition, erosion characteristics are greatly influenced by strength and elongation properties of materials.
