Penentuan Efektivitas Desain Unit Cyclone untuk Mereduksi Partikulat Di Udara

Abstract

Cyclone is one of air pollution control devices for separating the gas phase to the solid phase to reduce particulate emissions in industrial area. Sometimes the cyclone performance does not have significant influence to reduce particulate, because the best approach to determine the cyclone dimensions and efficiency that appropriate with the air flow rate input is unknown. Therefore, the main purpose of this research was to determine the best cyclone dimensions and efficiency, criteria to recommend the appropriate design for particulate control device in industrial activity. There are three versions of cyclone design standard dimension (Lapple, Swift and Stairmand). The calculation processes used Barth, Leith-Licht and Ionizia-Leith Models, with variations of gas inlet velocity (10, 15,20 m/s) and volumetric flow rate (60000,65000,70000 m3/hr). The calculation results obtained that the lower volumetric flow rate and the higher gas velocity at cyclone inlet will provide the higher particulate removal efficiency value.
