Abstract
A fiber bed assembly for a mist eliminator that operates at high efficiency and inhibits re-entrained liquid from leaving the mist eliminator. The fiber bed assembly has a construction that facilitates rapid drainage of liquid collected by the fiber bed. A pre-filter media can be employed upstream of the primary collection media to remove larger liquid drops. The pre-filter media can be used in unique combination with other features to reduce liquid re-entrainment, and/or allow increased flow capacity.
Claims50
A fiber bed assembly for a fiber bed mist eliminator used to remove aerosols and/or wetted soluble solids from a moving gas stream, the fiber bed assembly comprising:
- a fiber bed support having a wall defining an upstream space and a downstream space, the wall including openings therein to permit the gas stream to move generally freely through the wall from the upstream space to the downstream space;
- a fiber bed supported by the fiber bed support and generally covering the wall openings so that the gas stream passes through the fiber bed moving from the upstream space to the downstream space, the fiber bed comprising collecting fiber media and drainage media located on a downstream side of the fiber media, the drainage media comprising channel strips along the height of the fiber bed, the channel strips being arranged to define overlapping regions in which one of the channel strips overlaps an adjacent one of the channel strips.
A fiber bed assembly for a fiber bed mist eliminator used to remove aerosols and/or wetted soluble solids from a moving gas stream, the fiber bed assembly comprising:
- a fiber bed support having a wall defining an upstream space and a downstream space, the wall including openings therein to permit the gas stream to move generally freely through the wall from the upstream space to the downstream space;
- a fiber bed supported by the fiber bed support and generally covering the wall openings so that the gas stream passes through the fiber bed moving from the upstream space to the downstream space, the fiber bed comprising a collecting fiber media and a pre-filter media on an upstream side of the collecting fiber media, the pre-filter media including a layer of collecting fiber media and drainage media disposed generally between the collecting fiber media and the collecting fiber layer.

- a fiber bed support having a wall defining an upstream space and a downstream space, the wall including openings therein to permit the gas stream to move generally freely through the wall from the upstream space to the downstream space;
- a fiber bed supported by the fiber bed support and generally covering the wall openings so that the gas stream passes through the fiber bed moving from the upstream space to the downstream space, the fiber bed comprising collecting fiber media and drainage media located on a downstream side of the collecting fiber media, the fiber bed being generally tubular in shape having upper and lower ends, and wherein the downstream space is at least partially located in an interior of the tubular fiber bed;
- a re-entrained liquid collection member located at least partially in the downstream space on the interior of the tubular fiber bed.
