A fiber bed element and process for removing aerosols from gas streams wherein a bed of fibers is packed to a desired packing density between two foraminous screens. A substantial portion of the fibers in the bed are positioned in a generally parallel arrangement such that the element can be mounted in an operative position with such substantial portion of the fibers extending in a generally vertical direction to enhance drainage of collected aerosols from the element to thereby allow-operation at even high bed velocities with reduced re-entrainment of collected liquid and thereby increase the total collection efficiency of the element. In the process, the bed element is mounted such that the parallel fibers extend in a generally vertical direction and the gas to be treated is passed through the bed at a predetermined velocity.
A fiber bed element for removing aerosols from a moving stream of gas, comprising a bed of fibers having a substantial portion of the voidage between the fibers of the fiber bed extending, with substantial continuity, in a generally vertical direction and a collecting layer wherein said fibers within said bed of fibers, hereinafter referred to a said drainage layer, have a mean diameter of 15-75 microns, said drainage layer being positioned in contact with said collecting layer, said collecting layer having randomly-oriented fibers having a mean diameter of 2-15 microns and being packed to a density greater than the packing density of the fibers in said drainage layer.
A fiber bed element for removing aerosols from a moving stream of gas, comprising a bed of fibers having a substantial portion of the voidage between the fibers of the fiber bed extending, with substantial continuity, in a generally vertical direction and a collecting layer wherein said fibers within said bed of fibers, hereinafter referred to as said drainage layer, have a mean diameter of 75-300 microns, said drainage layer being positioned in contact with said collecting layer, said collecting layer having randomly-oriented fibers having a mean diameter of 20 to 75 microns.
A method of removing aerosols from a gas, comprising:
