“…It is applied in fields such as vehicle transportation, road construction, rock blasting of water conservancy and hydropower project, coal handling systems of power plant, tunnel construction, stock ground of metallurgical enterprise, concentrating mill, mine and other producing dust places,but the dust suppression effect of conventional single nozzle spray was limited. Improving dust suppression effect was researched on charged water spray, high-pressure spray, magnetized water spray ,and pressure gas and water spray,which are limited in term of dust reduction efficiency and applicability [1][2][3][4][5][6][7] . Therefore, the trial tests on self-priming spray magnetization dust suppression were carried out on the basis of previous studies.…”

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%.
