Rotating concentric {37 homogeneous turbulence{38 {0 fabric bag gas cleaner method
Abstract
Abstract This invention relates to the application of couette motion caused by centrifugal forces in a rotating concentric ''''homogeneous turbulence'''' fabric bag gas cleaner, to provide uniform separation of gaseous, liquid, and solid particulates in a carrier fluid, by adjustable levels of imposed discrete ''''homogeneous turbulence'''' established by Taylor circular couette motion with a multiple array of secondary flow cellular vortices in the annulus between the inner perforated cylinder and the outer perforated cylinder, with both cylinders rotating in the same direction. When the outer cylinder rotates in the opposite direction to the inner cylinder, an adjustable level of imposed discrete spiral band of turbulence in a travelling wave, will ripple the fabric bags, will move either up or down in the annulus, and will clean the collected material from the inner surface of the fabric bags.
