Abstract

The perforated top plates of a carbon bed solvent recovery adsorber are spring-loaded down onto the activated-carbon bed, to prevent uneven distribution of the carbon granules during solvent recovery.

Carbon Bed Plate Hold Down Assembly

The perforated top plates of a carbon bed solvent recovery adsorber are spring-loaded down onto the activated-carbon bed, to prevent uneven distribution of the carbon granules during solvent recovery.

During solvent recovery, the solvent-carrying air passes into the top cavity 10 of cylindrical metal vessel 11, then downward through perforated, top, stainless steel plates 12 and 13, through carbon bed 14 and perforated support plate 15, to the vessel's bottom cavity 16 where the clean air is evacuated. In order to reactivate the carbon bed, steam is passed in a reverse direction, from cavity 16 to cavity 10.

With standard, fixed-edge top plates, initial carbon settling and prolonged cycling are likely to produce uneven thickness of the carbon bed. This uneven settling of the carbon layer is prevented by a number of spring-loaded pressure feet 17 which operate to exert a downward force on each of the top plates 12 and
13. The top plates cooperate with a number of such pressure feet, which are spaced down the axial length of vessel 11. During maintenance, the pressure feet are manually lifted, against the spring force, and can be held in that elevated position by inserting a pin through a hole formed in the vertical shaft which is attached to each foot.
