Different Cyclone model for Dust collector supplier Philippines
There are basically three most commonly used cyclone designs for dust collector supplier Philippines. Which includes (1) Shepherd and Lapple – 2D2D cyclone model (2) Parnell and Davis – 1D3D cyclone model and then (3) Kaspar and Parnell – 1D2D cyclone model. The D’s in the 2D2D designation refer to the barrel diameter of the cyclone. The numbers preceding the D’s relate to the length of the barrel and cone sections, respectively. A 2D2D cyclone has barrel and cone lengths of two times the barrel diameter, whereas the 1D3D cyclone has a barrel length equal to the barrel diameter and a cone length of three times the barrel diameter. The configurations of these three cyclone designs are shown in figure below
The 1D3D and 2D2D are the most efficient collectors for fine dust. The 1D3D cyclone are more efficient cyclone than the 2D2D for fine dust collection by dust collector supplier Philippines, this would suggest that the cut-point of the 1D3D is significantly lower than the 2D2D cyclone design. On the other hand, there is a significantly lower PM concentrations emitted by the 1D2D cyclone designs when the inlet air stream contained cotton gin trash/fine dust and the gin trash contained a relative high fraction of lint fiber (high lint gin trash/fine dust).
The Number of Effective Turns (Ne) for the dust collector supplier Philippines:
The number of effective turns in a cyclone is the number of revolutions the gas spins while passing through the cyclone outer vortex. A higher number of turns of the air stream result in a higher collection efficiency. dust collector supplier Philippines uses the below formula for Ne calculation.
N = 1/H (Lb + (Lc/2))
where N = number of turns inside the device (no units)
H = height of inlet duct (m or ft)
Lb = length of cyclone body (m or ft)
Lc = length (vertical) of cyclone cone (m or ft).
The Lapple model for N produces an excellent estimation of the number of turns for the 2D2D cyclone designs.
Cut point Diameter:
The cut-point of a cyclone is the aerodynamic equivalent diameter (AED) of the particle collected with 50% efficiency. As the cut-point diameter increases, the collection efficiency decreases as per dust collector supplier Philippines.
Dp = { 9µW / 2∏NeVi (Pp -Pa)} 1/2
Where, dp = diameter of the smallest particle that will be collected by the cyclone
µ = gas viscosity (kg/m. s)
W = width of inlet duct (m)
N = 1/H (Lb + (Lc/2))
Vi = inlet gas velocity (m/s)
Pp = particle density
pa = Density of fluid
