Abstract
Industrial spray dryers are used to convert the sludge product into powder form. The size of powder product is in the range of microns and it is necessary to separate the powder from process air. Cyclone, Bag filter and Scrubber are most widely used devices in particle separation process. The cost of bag filter and scrubber is approximately three times that of cyclone. Hence by improving the efficiency of cyclone, the load on Bag filter and Scrubber can be reduced.This study was to analyze the cyclone separator using CFD in ANSYS Fluent. These design of cyclone which will have greater efficiency than the existing design cyclone. The objective was achieved by introducing an invert cone at bottom part. The trajectory of the particle, flow path of the gas and the drop in pressure were analyzed. The effect of variation of bottom cone dimension in modified cyclone separator is considered in this project. The efficiency of the existing cyclone from CFD analysis is found to be 95.7 %. The pressure drop in the modified cyclone separator from CFD analysis is found to be increase by 5 mmwc compared with the CFD results of present cyclone separator. The efficiency of modified cyclone was found to be 98%. Thus the modified cyclone separator is 2% more efficient than present cyclone separator.
