Tests on droplets and dust suppression characteristics with self-priming spray magnetization

Abstract

ABSTRACT:To improve the effect of spray and dust reduction, self-priming spray magnetization dedusting was put forward. Moreover, some experiments on droplets and dedusting characteristics were carried out, such as traditional single-nozzle spray, self-priming non-magnetic spray, selfpriming spray with magnets on throat, self-priming spray with magnets on the diffusion tube, and self-priming spray with magnets both on the throat and diffusion tube respectively. The results showed that the SMD value of the self-priming spray was reduced by approximately 12% to 20% and dust reduction efficiency was increased by approximately 5% to 7% compared with the conventional single nozzle, while the SMD value of self-priming spray with magnets was reduced by approximately 10% to 15% and dust reduction efficiency was increased by approximately 6% to 15% compared with the self-priming spray without magnets, the SMD value of self-priming spray with magnets both on the throat and the diffusion tube was less than that of self-priming spray plus magnets on throat or diffusion tube alone, and the dust reduction efficiency was increased by approximately 5%.
