Abstract |
DOP aerosol particles with geometric mean diameter of 0.5~3.0m, geometric standard deviation of 1.1~1.3 and total number concentration of 1,500~8,000 particles/cm3 were used to determine collection efficiencies of a packed wet scrubber with respect to particle size. The tested operating variables included air velocity and water injection rate. It was shown from the experimental results that the collection efficiencies increased with increasing water injection rate and decreasing air velocity. Meanwhile, as for the particle size variation, all of the collection efficiency curves increased rapidly between 0.57~1.41m for the range of water injection rate above 30L/min. It was also seen that the collection efficiency of a packed wet scrubber is mainly governed by the mechanism of inertial impaction. |
