Powierzchnia międzyfazowa w poziomych przeciwprądowych skruberach natryskowych

The efficiency with -which solid and gaseous pollutants are separated from flue gases via a spray column depends primarily on the size of the interfacial surface. The study reported in this paper concentrated on the interface developing on the spray-liquid drops in a horizontal counter-current spray column. The liquid was sprayed via a streamed-centrifugal atomizer which provided a cone-shaped stream of droplets. The interface was found to be affected by three major factors—gas velocity, liquid rate and drop diameter. The results were correlated in terms of two equations: one was valid for gas velocities in the spray column lower than 4 m/s, the other one for gas velocities between 4 and 8 m/s. The values of the multiple correlation coefficients for the two equations approached unity.
