Nov 25, 2024 · In this guide, we explain the sizing and selection of hydrocyclones in simple terms – covering the key design parameters, hydrocyclone calculations for determining the correct dimensions, and what to consider when comparing different cyclone models. Some of them are: Airflow What is the airflow going through the cyclone? The cyclone size is directly tied to the amount of air going through it. Such options include the different styles of centrifugal separators offered but you can also use the calculations to compare centrifugal separators to vane and mesh pad style separators. Figure below shows hydrocyclones typical proportion geometry. Sysmatec Cyclone calculation This example shows how to use the software to calculate a cyclone. Diameter: The diameter of the cyclone separator influences its capacity and efficiency. These types of separators use cyclonic action to separate particulates from a gas stream. When removing particulate matter from liquid, a hydrocyclone is used; while from gas, a gas cyclone is used. Known parameters air flow rate: 3 m3/s pressure: 1 bar gas is air at room temperature: 293 °K solid density is : 1500 kg /m3 solid distribution is: Jul 16, 2013 · How to Size a Cyclone or Hydrocyclone has a well establish step-by-step process for which Richard A.
