摘要：

The overall particle collection efficiencies of spray scrubbers using monodisperse droplets of 100, 500, and 1000 microns diameter were calculated for the cases of evaporating and condensing droplets. The properties of the gas at the inlet to the spray scrubber were maintained constant at 150 degree F, 100% relative humidity, and 1 atmosphere pressure. At the liquid entrance to the spray scrubber, the water droplet temperature was 50 degree F for the condensing case and 180 degree F for the evaporating case. The liquid to gas flow rate ratio for all the calculations was held constant at 4 gal/1000 acf. The gas velocity in the co-current spray tower was 1 ft/sec in the downwind direction. The calculation results show that for the particles in the 0. 01 to 10 mu m diameter range, the overall spray scrubber particle collection efficiency is greater with the cooler 50 degree F water (condensing case) than with the warmer 180 degree F water (evaporating case).
