Fiber bed assembly including a re-entrainment control device for a fiber bed mist eliminator

A fiber bed assembly for use in a mist eliminator for removing aerosols and/or wetted soluble solids from a moving gas stream, the fiber bed assembly comprising:

• a fiber bed support;
• a fiber bed supported by the fiber bed support to define an upstream space and a downstream space, the fiber bed being constructed to pass the gas stream through the fiber bed moving from the upstream space to the downstream space, the fiber bed comprising collecting fiber media, and the fiber bed being generally tubular in shape such that a downstream surface of the fiber bed defines the downstream space;
• a re-entrainment control device located at least partially within the downstream space, such that at least a portion of the gas stream passes through the re-entrainment control device, the re-entrainment control device being shaped to change the direction of the average flow path of the gas stream as the gas stream passes through the re-entrainment control device so as to cause aerosols and/or wettable solids contained therein to be separated from the gas stream by inertial force, wherein the re-entrainment control device comprises a frame including at least one support member, and spaced apart baffles mounted on the at least one support member in a stepped arrangement to serially change the direction of the average flow path of the gas stream as the gas stream passes each baffle, the stepped arrangement of baffles including baffles on a first side of the downstream space and baffles on a second side of the downstream space opposite the first side, the stepped arrangement of baffles including vertical spaces between successive baffles on the first side of the downstream space, the baffles on the second side of the downstream space being positioned horizontally opposite the vertical spaces between the baffles on the first side of the downstream space.
