THE INFLUENCE OF ANGLE ON PARTICLE SEPARATION BY CYCLONE
Keywords:
Separation, Dust particles, Cyclone, Design, ResearchAbstract
In the presented article, a study was conducted on the influence of the structural angle on particle separation and collection efficiency in a straight-through cyclone, as well as its hydraulic resistance. Through software modeling and analysis, we obtained the trajectories of dust particles with various diameters at different points within the cyclone. This guided the selection of specific designs for experimental investigation, which were then manufactured using a 3D printer.
The size of the particles to be separated from the air plays a crucial role. Particles smaller than 5 μm deserve particular attention because their smaller size makes them more susceptible to the influence of centrifugal force.
The subject of this research is the impact of cyclone constructive angles on gas-dynamic characteristics.
The object of the report focuses on cyclones as devices for separating particles from gas streams.
The purpose of this study is to quantitatively determine and analyze the influence of changes in the cyclone's constructive angles. To achieve this, the following tasks were completed: theoretical aspects of gas flow and particle movement within the cyclone were analyzed, existing scientific research was reviewed, experiments were conducted, and recommendations for optimal constructive angles were formulated.
An experimental methodology was employed.
The results indicate that the separated, inclined particles contribute to increasing the collection efficiency of residues in the cyclone. This occurs by creating spaces with near-zero gas velocities between adjacent particles, forming "buffer zones."
In these zones, separated particles detach from the swirling dust-gas flow in the annular space, preventing them from bouncing back into the main flow.
The analysis of the results was conducted from two perspectives: determining the efficiency of the design for specific materials and developing an optimal configuration for fine dust particles.
Sand separation occurs in the shortest amount of time, while wood particles take the longest to be collected. The cyclone exhibits the lowest efficiency when collecting ash.
The cyclone operates most effectively with heavy and compact materials like sand, achieving maximum separation in minimal time.
