Cyclone Collection Efficiency Calculator
Cyclone collection efficiency at the edge of the cyclone core as where a is a friction factor that barth as sumed to be 0.02 and a = 1 1.2(b d).(8) figure 3 is barth's plot of efficiency versus. The collection efficiency of cyclones varies as a function of particle size and cyclone design. cyclone efficiency generally increases with (1) particle size and or density, (2) inlet duct velocity, (3) cyclone body length, (4) number of gas revolutions in the cyclone, (5 ) ratio of cyclone body diameter to gas exit diameter,. The collection efficiency of the cyclone with vortex finder 15 7 a was the same as that with 7 a, which means the cylinder part with large diameter did not affect the spiral flow patterns, although it was expected that the cylinder part with large diameter could form a well defined outer spiral flow. download : download full size image; fig. 4. The collection efficiency of particles in a gas cyclone is mainly determined by the fluid drag and centrifugal force. when the particle size decreases, the fluid drag increases exponentially, much faster than the centrifugal force, and thus, the fine particles cannot be effectively separated and removed [  ,  ,  ]. The collection efficiency also known as the capture or recovery rate is a measurement of a cyclone’s ability to separate particles from the flowing gas stream. because particles have different sizes, the efficiency rating is usually given for varying particle sizes.
Pdf A Cfd Study On The Prediction Of Cyclone Collection
Tools for increased cyclone efficiency: parallel cyclone arrangements • one of best tools for getting higher collection efficiency: for a given power consumption and family of cyclones, splitting the flow into parallel streams allows the use of more efficient, smaller cyclones: “ cyclones are more efficient than large ”. Predicting cyclone efficiency louis theodore and victor de paola manhattan college one type of particulate collector in wide use is the cyclone. the prediction of cyclone performance is dealt with exten sively in the literature and includes methods which" vary considerably in complexity.1"3 a relatively simple procedure. A major limitation of any fluid mechanics model for cyclone separators is the inability to predict the agglomeration of fine particles with larger particles, which has a great impact on cyclone collection efficiency.
