Design and analysis of a separator for aluminium dust particle collection

The project aimed to design and analyze of a separator for aluminium dust particle collection which would be analyzed and validated using CFD software. The goal of the project was to design a separator that could reduce the aluminium dust from the air of an industrial environment.

Cyclone separators are considered as the most common and widely used method of separating solid particles from fluid. The main focus of this paper is to design a separator that could effectively improve the air quality of an industrial working environment by considering factors such as the nature of the particles and the restrictions on the device such as size and operating condition. To do so, a sample of the dust sample was studied to determine the characteristics of and dust. An initial separator model which satisfied the separation condition was developed, and a second model was developed with the goal of optimizing and reducing the overall size of the separator was developed. All models developed were subjected to CFD simulation to analyze the flow patterns, separation rate at various particle diameter as well as validating the theoretical values predicted. The simulation results presented showed how the change in parameters improved the separation efficiency of the particle. The total height of the model was approximately 20% smaller than the initial proposed design while the separation rate across all particles improved by 5% to 10%. The results obtained concluded that the efficiency of the particle collection is dependent on the area of the barrel inlet and the depth of the vortex finder.
