Rotating concentric homogeneous turbulence electrostatic precipitation gas cleaner method
Abstract
Abstract This invention relates to the application of couette motion caused by centrifugal forces in a rotating concentric ''''homogeneous turbulence'''' electrostatic precipitation 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 double rows of secondary flow cellular vortices in the annulus between the inner perforated cylinder and the outer perforated cylinder, with the cylinders rotating at about the same velocity in opposite directions. When the outer cylinder rotates about three times faster and in the opposite direction to the inner cylinder, with the electrical power turned off, an adjustable level of imposed discrete spiral band of turbulence in a travelling wave, will move up or down in the annulus, and will clean the collected material from the surfaces of the discharge and collecting electrodes.
