The Experimental Study of Performance Ejecting Dust Collector in Mine

Abstract

For mining gas outburst coal dust pollution problems caused by dry drilling, this paper proposes a new mine wet compressed air ejecting dust collector. The energy-efficient experimental project of compressed air ejecting dust collector was designed, and tested the performance of the dust collector in the experiment. To ensure the structural parameters unchanged, testing the change of import static pressure, ejecting air flow, ejecting ratio and noise of different pipe lengths dust collector with compressed air pressure respectively. The results showed that: the ejecting performance parameters of the length of 1000mm pipes dust collector is better than the dust collector which the length is 1300mm. When compressed air pressure are 0.25MPa and 0.3MPa, the total dust removal efficiency of the dust collector which the length is 1000mm pipes reached 97.6% and 97.9% respectively, are reflect the better performance of dusting.
