Abstract
Abstract The drying medium (T) is driven through the adsorbent (5) of the adsorption cell (1) in the same direction as the process medium (P). Initially it is ejected through an auxiliary output (19) and a device (26) for removal of dampness and then is changed-over towards a main output (18) and preferably into the workroom (A).

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
104 words
Method for the removal of the residual dampness from an adsorption cell having adsorbent through which processing medium passes in a processing direction and at least an auxiliary first outlet and main second outlet after desorption by water vapor with a drying medium comprising the steps of driving the drying medium through the adsorbent in said processing direction and initially during a first drying phase or interval through an auxiliary first outlet while during a second phase or interval after having caused a diminished dampness through a main second outlet to prevent most of the residual dampness from exiting through said main second outlet.
Claim 2
Dependent Claim
104 words
Method for the removal of the residual dampness from an adsorption cell having adsorbent through which processing medium passes in a processing direction and at least an auxiliary first outlet and main second outlet after desorption by water vapor with a drying medium comprising the steps of driving the drying medium through the adsorbent in said processing direction and initially during a first drying phase or interval through an auxiliary first outlet while during a second phase or interval after having caused a diminished dampness through a main second outlet to prevent most of the residual dampness from exiting through said main second outlet.
Claim 3
Dependent Claim
133 words
Device for the removal of the residual dampness from an adsorption cell having adsorbent through which processing medium passes in a processing direction and at least an auxiliary first outlet and main second outlet after desorption by water vapor with a drying medium comprising said adsorption cell including an adsorption chamber arranged between two chambers for the inlet and outlet of a process medium during an adsorption interval, of water vapor during a following desorption interval and a drying medium during a following drying interval, said device further comprising means for opening said auxiliary first outlet for the drying medium during a first drying interval before opening said main second outlet for the drying medium during a second interval to prevent most of the residual dampness from exiting through said main second outlet.
Claim 4
Dependent Claim
133 words
Device for the removal of the residual dampness from an adsorption cell having adsorbent through which processing medium passes in a processing direction and at least an auxiliary first outlet and main second outlet after desorption by water vapor with a drying medium comprising said adsorption cell including an adsorption chamber arranged between two chambers for the inlet and outlet of a process medium during an adsorption interval, of water vapor during a following desorption interval and a drying medium during a following drying interval, said device further comprising means for opening said auxiliary first outlet for the drying medium during a first drying interval before opening said main second outlet for the drying medium during a second interval to prevent most of the residual dampness from exiting through said main second outlet.
Claim 5
Dependent Claim
28 words
Device as defined in claim 2 and further comprising, means for removal of vapor, and an auxiliary pipe connecting said auxiliary first outlet to said means for removal.
Claim 6
Dependent Claim
26 words
Device as defined in claim 3 wherein said auxiliary first outlet is at the bottom of said adsorption cell and comprises means for draining condensate therefrom.
Claim 7
Dependent Claim
39 words
Device as defined in claim 3 and further comprising a mud filter having a mud outlet opening connected in said auxiliary pipe with a mud valve and to said first auxiliary outlet to facilitate clearance of said mud filter.
Claim 8
Dependent Claim
30 words
Device as defined in any one of the claims 2 to 5, wherein said main second outlet has a collar extending through and above the bottom of said adsorption cell.
Claim 9
Dependent Claim
38 words
Device as defined in claim 2 wherein said adsorption cell has a bottom chamber with bottom plate provided with openings for the connection of all pipes to be connected to the bottom chamber including said auxiliary first outlet.
Claim 10
Dependent Claim
22 words
Device as defined in claim 7 wherein said adsorption cell includes a cover plate having openings and interchangeable with said bottom plate.
