Evaluation of the efficiency of rectangular separators to collect the particles from the gas flows

Abstract

Analysis of the separation devices’ operation and improvement of efficient gas mixture purification processes is relevant issue and is a great interest for the specialists of different industrial brunches. Modernization of internal devices in the cases of existing separators is the main goal in the field of increasing the efficiency of fine dispersed particles’ collection process. Design of a rectangular separator with a number of I-beams has been developed. Operation principle of the device is described. When the multiphase flow moves between the device elements, the centrifugal force appears, that ensures the coagulation of finely dispersed liquid drops, facilitating their uniform settling on the entire surface of I-beams. The advantage of these separators is noted. High values of centrifugal force are achieved at relatively low gas flow rates that allows to carry out the separation processes at low energy costs. Numerical study of the gas mixture flow through the rectangular separator is shown at different values of the flow rate and different diameter of particles. The results of separation efficiency are shown for different designs of I-beams. Increase in the rate leads to efficiency increase. Ranges of efficient operation of the separator have been determined. Studies showed the advisability of using the rectangular separators to purify the gases from finely dispersed particles.
