Patent ID: 8632616

Claim:
A fiber bed assembly for a forward-flow fiber bed mist eliminator used to remove aerosols from a moving gas stream, the fiber bed assembly comprising: a fiber bed support having an upper end, a lower end, and a substantially cylindrical wall extending between the upper and lower ends defining an exterior upstream space outside the wall and an interior downstream space inside the wall, the wall including openings therein to permit the gas stream to move generally freely through the wall from the exterior upstream space to the interior downstream space; a fiber bed supported by the fiber bed support and generally blocking the wall openings so that the gas stream passes through the fiber bed moving from the exterior upstream space to the interior downstream space, the fiber bed comprising collecting fiber media and having a top, a top end margin, a bottom, a bottom end margin, an upstream surface and a downstream surface; a base adjacent the lower end of the fiber bed support blocking movement of the gas stream down through a lower end of the interior downstream space, the base including a side wall arranged in opposed relation with a portion of the downstream surface of the fiber bed for blocking flow of the gas stream from the fiber bed to the downstream space through said downstream surface portion, the side wall including a top and a bottom; an opening adjacent an upper end of the fiber bed support for exit of the gas stream from the interior downstream space; a gas-impervious veil spaced upstream from the downstream surface of the fiber bed at the bottom end margin of the fiber bed, the veil having an upper end and a lower end and being constructed to block flow of the gas stream into at least a portion of the fiber bed to provide a gas-shielded drainage area in the fiber bed between the gas-impervious veil and the downstream surface of the fiber bed for drainage of aerosols from the fiber bed, the lower end of the veil being spaced upward from the bottom of the fiber bed, the lower end of the veil being spaced downward from the top of said side wall of the base, and the upper end of the veil being spaced upward from the top of said side wall of the base.
