Simulation of a System for Reducing Gases Emitted in a Steel Casting Process by Two-Stage Centrifugal Separation

Abstract

This study proposes the simulation of a system for reducing polluting gases produced by a steel foundry by two-stage centrifugation. This simulation seeks to verify the physical principle of centrifugation in two cyclones (Stairmand and Swift types) in serial connection: one with its inlet at the outlet of the other, based on initial gas inlet conditions, as well as the design equations of this equipment. Likewise, it's intended to demonstrate the efficiency of this system by entering the mass composition of the gas, in particulate matter (PM) terms, measuring its new composition at the output, after simulating the gas and particle dynamics. For this, Ansys CFD and Ansys Fluent software are used (with previous data analysis and processing), and Python programming techniques to automate calculations and obtain the optimal design values for the cyclones. This system seeks to be an alternative to a universe of expensive and enormous equipment related to environmental pollution control.
