Abstract
Many studies have shown that pulsed air jet has a high removal power with little air consumptions. The purpose of this study was to elucidate dust removal mechanism of pulsed air. This paper presents measurement results obtained on the wall pressure measurement and the air consumption measurement. Measurement results of the wall pressure measurement show the most efficient removal condition is duty factor 40% at frequency 5[Hz]. In the air consumption measurement, as compared with normal air jet, the condition have realized a 56% reduction of air consumptions. In the particle removal experiment, all conditions have high removal rate. The results show the particle removal rate and the air consumption are independent. Here we have confirmed the pulsed air is a technique that can reduce air consumption.
