It is considered to be a valid method for using the waste water of an industrial plant to control the air pollution of the exhaust gas, which is one of the main sources of atmospheric particulate matter. A GLCA (Gas-Liquid Cross-flow Array) wet scrubber system, already described in detail by Zhu J. et al , is proposed to be a dust separator to remove particles in the exhaust gas. A continuous and regular liquid column array is formed under the force of gravity with a holed distributor, by which the particles will be captured when the dusty gas flows through the column array.
Tests were executed on a lab scale test rig for different operation and apparatus parameters and the fractional separation efficiency and the pressure drop were measured. Using a simplified PM2.5 definition , a method will be presented how the minimum number of water column unit rows in series n could be found, with the aim to reach a certain PM2.5 limit value. Further a quality factor is used to optimize other parameters, e.g. the gas through-put velocity...
