Bag filters of fibrous components are widely used to clean exhaust gas. It is reported that filter damage during dust collection involves erosion wear caused by particle collision. Thus, it is necessary to determine the life of bag filters in a hot environment and to clarify the erosion mechanism of fibrous materials. Experiments and evaluation methods were developed to investigate the erosion of fiber at high temperatures. The experiments involved reproducing the erosion of fibrous materials in various temperatures. Analysis of the relationship between the erosion damage rate of a specimen and the total kinetic energy of particles before colliding indicates the erosion resistance of fibrous materials at various temperatures. Using the suggested damage energy curve, we can evaluate the erosion wear characteristics of fiber under different experiment conditions.

INTRODUCTION Currently, reduction of the environmental impact of industrial activities is a major concern of many industries and governments. Bag filters composed of fibrous materials are widely used to remove harmful gasses, dioxins, heavy metals, and dust from garbage incinerators with high efficiency. In addition, bag filters are used for many waste gas processing systems, including industrial waste incinerators. 1) Moreover, it is the only method for use in garbage incinerators that is permitted by the Ministry of Health, Labor, and Welfare of Japan. However, when bag filters are damaged by long-term or irregular use, internal drift and harmful gasses flow out of the facility and pollute the peripheral environment. While bag filter damage results from deterioration of materials due to chemical reactions and high temperature, experiments and investigation indicate that wear damage also results from the collision of particles in waste gas (dry sand erosion). 2)In studies of the erosion of structural materials, many results have been obtained from basic studies mainly of metals and inorganic materials such as conducted by Hashimoto et al. over a long time. 3,4) Researchers (e.g., Harsha et al. 5) and Barkoula et al. 6) ) have investigated the influence of impact angle, speed, and form of colliding particles, as well as the erosion resistance of matrix resin, for GFRP and CFRP, which are frequently used for industrial applications. While FRP composed of fragile glass fiber and carbon fiber has low erosion resistance, we used super fiber, which is a polymer fiber, to develop FRP with high specific strength and excellent solid particle erosion resistance. [7][8] No studies have focused on the erosion of fibrous materials; therefore, many points remain unclarified. We focused on the erosion of fibrous materials and developed related experiments and evaluation methods and manufactured a prototype of the developed measuring device. Using this device, we reproduced the erosion of fiber and its composites, and measured and evalu...

The damage characteristics of dry sand erosion of fiber in a hot environment are important for bag filters for garbage incinerators. In this study, we use a newly developed measuring device and evaluation method to investigate the erosion resistance of three types of fiber used for bag filters at a site in a hot environment. We found that the erosion resistance of all three types of fiber decreased as the ambient temperature increased. The erosion resistance of fiber in a hot environment is largely influenced by the decrease in fiber strength in such an environment.
