Fiber collecting media strip for a mist eliminator

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 an elongate fiber bed collecting media strip wrapped around the fiber bed support in multiple turns, at least some of the turns extending along a spiral path, the fiber bed collecting media strip being generally flat and at least some of the turns overlapping adjacent turns.

A fiber bed collecting media strip for use in making a fiber bed for a fiber bed mist eliminator used to remove aerosols and/or wetted soluble solids from a moving gas stream, the fiber bed being adapted to generally cover a support structure of the fiber bed mist eliminator for generally blocking flow of the gas stream through the support structure except for through the fiber bed, the fiber bed collecting media strip comprising an elongate strip formed of fibers capable of removing aerosols from the moving gas stream, the strip being sized for covering the support structure by wrapping around the support structure in multiple overlapping turns, the strip having opposite, generally flat faces, at least one of the faces having an alignment marking thereon positioned for aligning the overlap of an adjacent turn of the strip.
