Abstract
A space and energy saving adsorber unit comprising two adsorber beds arranged in a common housing. The upper adsorber bed, disposed essentially vertically, is contained by gas permeable vertical walls, thereby permitting gas to be treated in the horizontal direction. The second adsorber bed, located beneath the first bed, slopes downwardly from an upper apex with increasing distance from a vertical central axis and is also enclosed, at least in part, by gas permeable walls. During regeneration of the system where water might be condensed in the bed, the condensate flows out of the bed without damaging the adsorbent.
Claims25
In an adsorber unit having two adsorber beds arranged in a common housing, in which a first adsorber bed is enclosed by elongated gas-permeable walls that are disposed substantially vertically and in mutual opposition thereto, so that a substantially horizontal gas flow can occur in the first adsorber bed, and wherein a second adsorber bed is arranged below and in flow communication with the first adsorber bed, wherein the improvement comprises said first adsorber bed being fabricated in the form of an annular cylinder, the interior of which is in communication with a conduit means for feeding and/or discharging gas, said annular cylinder being arranged coaxially to said second adsorber bed;
- said second adsorber bed being arranged so that it has an upper apex lying in a vertical central axis and descending flanks which slope in the downward direction with increasing distance from the central axis, said second adsorber bed being rotationally symmetrical about said vertical central axis, said descending flanks being at least partially enclosed by gas-permeable walls, said second adsorber bed having a substantially constant adsorber layer thickness in the region of the descending flanks;
- and a charging pipe being positioned within said common housing leading from the apex of said second adsorber bed through the interior of said first adsorber bed into an upper zone of said common housing.
In an adsorber unit having two beds arranged in a common housing, in which a first adsorber bed is enclosed by elongated gas-permeable walls that are disposed substantially vertically and in mutual opposition thereto, so that a substantial horizontal gas flow can occur in the first adsorber bed, and wherein a second adsorber bed is arranged below and in fluid communication with the first adsorber bed, wherein the improvement comprises said second adsorber bed being arranged so that it has an upper apex lying in a vertical central axis and descending flanks which slope in the downward direction with increasing distance from the central axis, said descending flanks being at least partially enclosed by gas-permeable walls, and a central pipe being positioned within said common housing leading from the apex of said second adsorber bed through the interior of said first adsorber bed into an upper zone of said common housing.
