Performance tests on a wet type dust collector were made using four different test dusts to determine a relationship between dust collection efficiency, particle size and size-distribution., collector nozzle velocity, and collector geometry. Dust laden air entered the collector and impinged upon a water surface at nozzle velocities in the order of 10,000 fpm. The fraction of dust which penetrated the collector was found to fit the equation
[formula omitted]
π = collector penetration (100% minus efficiency)
ø[subscript]g = Geometric Coefficient of Variation of the test dust
[formula omitted]
V = collector nozzle velocity in thousands of fpm
j = [formula omitted]
π was found to vary from 0.121 percent with Corundum dust to 8.68 percent with Alundum dust. The nozzle velocity range was from6840 fpm to 14,130 fpm and the range of J was from 6.85 to 27.4.
Corundum dust was found to have a value of ø[subscript]g equal to 0.123 with a geometric mean diamter, [formula omitted] , of 11.9 microns while ø[subscript]g and [formula omitted] for Alundum were calculated to be 0.521 and 4.84 microns respectively. The four test dusts were sized by a sedimentation method.
The Function equation fits the experimental results with an uncertainty of ± 12 percent. / Applied Science, Faculty of / Mechanical Engineering, Department of / Graduate
