IMPROVED FIBER BEDS FOR FIBER BED MIST ELIMINATORS

摘要

There is provided a fiber bed for removing liquid aerosols and soluble solids from a gas stream in a fiber bed mist eliminator. The fiber bed is in the form of a flexible mat having a void fraction of greater than about 0.89 and greater than about 700 net collection targets. The mat comprises a layer of collecting fibers having an average fiber diameter between about 1 and about 5 .mu.m. The collecting fibers are stabilized by a plurality of stabilizing fibers which penetrate into and are disposed interstitially within the collecting fiber layer. The improved fiber bed of the present invention is field-replaceable and, by utilizing fibers having a small average diameter, the thickness of the fiber bed may be reduced.
