INFLUENCE OF CYCLONE DESIGN ON THE SEPARATION OF VARIOUS PARTICLES
INFLUENCE OF CYCLONE DESIGN ON THE SEPARATION OF VARIOUS PARTICLES

Summary/Abstract: This research focuses on creating a multi-objective optimization for cyclones to reduce the impact of fine particulate matter on the human body. For this purpose, three main materials were used: sand, wood particles, and ash. Cyclone modeling was considered to generate conditions for creating a model with various parameters such as diameter, length, swirling velocity, separation of different particles, suction velocity, etc. These three materials were specifically chosen for investigation because they contain particles smaller than 5 μm, which deserve special attention as they are finer and affect human health. Observations show that in models designed with Solidworks, the model's efficiency for the specified materials is reduced. The percentage of unseparated particles increases, specifically those over 10%. In field studies, the efficiency of the respective cyclone design must be above 90% for the model to be considered adequate. The subject of the research is the influence of various structural parameters and elements of the cyclone on particle separation efficiency. The object of the research is cyclones as devices for separating two-phase gas-dust flows. The aim of the article is to analyze and summarize the key constructive characteristics of cyclones. To achieve this goal, the following tasks were completed: explaining the basic principles of cyclone operation, including the role of centrifugal forces and the formation of secondary flows; identifying and detailing the key constructive elements of the cyclone; analyzing their individual influence on separation efficiency for different particle sizes; summarizing the achieved research results; and proposing guidelines for future developments in cyclone design for more effective separation of gas-dust flows. Experimental studies were conducted with the aim of simulating aerodynamic flows and particle trajectories in the cyclone under different structural parameters. Combined methods were used. The results account for the efficiency of the cyclone model for each investigated material. This allows for the evaluation of the design under the respective experimental conditions. In conclusion, we can note that a universal separation design may not be equally effective for all types of materials
