Patent ID: 7387656

Claim:
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 composite fiber bed collecting media strip including; an outer layer comprising a mat of fibers constructed to provide structural integrity to the composite fiber bed collecting media strip, an inner layer comprising a mat of fibers constructed to provide structural integrity to the composite fiber bed collecting media strip, and an intermediate layer formed to have a higher collection efficiency than the inner and the outer layers, the intermediate layer being sandwiched between the outer and inner layers, the intermediate layer being non-needle punched, the outer layer and inner layer each comprising fibers having an average diameter of about 6 microns or more and the intermediate layer comprises fibers having an average diameter of about 5 microns or less, the fibers of the outer layer, inner layer and intermediate layer being made of glass, and the fibers of the inner and outer layers being needle punched.
