To master theoretical calculation for dust removal efficiency of high pressure atomization in an underground coal mine, the corresponding characteristics and were both comprehensively studied theory by virtue related theories hydromechanics aerosol. According to actual measurements flow coefficients angles X-type swirl nozzle, computational formula was derived atomized particle sizes such a nozzle conjunction with relevant empirical equation. Moreover, mathematical model applying mine also established deduce computation fractional efficiency. Then, Matlab adopted portray relation curve between influence factors. In addition, set up respirable total based on size frequency distribution equations. end, impacts characteristic parameters various efficiencies analyzed.
