Experimental Researches and Comparison of Cylindrical Multiple Levels Six–channel Cyclone

Abstract

The one-level, two-level and three-level six-channel cyclone is designed and constructed in Laboratory of Environment Protection in Vilnius Gediminas Technical University. The aim of this research is to measure air purification effectiveness in one-level, two-level and three-level cyclone when the particles are up to 20 µm in size. The experiments were performed when average airflow velocity in channels are 16 m/s, 12 m s and 8 m/s. The particle concentration in air inlet and outlet ducts is determined by weight method. By comparing the obtained data with each other, it was found that the best air cleaning efficiency is when air distribution ratio in cyclone's channels is 75/25. Granite particles are separated most effectively. Their separation effectiveness of the three-level cyclone is 92.8%. The lowest air purification efficiency is in one-level cyclone in comparison to two-level and three-level cyclones.
