Abstract
Abstract An apparatus for the adsorptive cleaning of gases comprises a rigid hermetically sealed housing provided internally with an inner vessel connected with the outer housing by a fluid carrying duct which is yieldable along the axis of the inner housing. The inner housing rests upon a grate and can be surrounded by a layer of thermal insulation. A filling of the adsorbent is provided in the inner vessel which is free from the usual bottoms carrying beds of adsorbent.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
172 words
An adsorber for cleaning of gases comprising: a pressure retentive thick-wall outer vessel provided with a duct at a bottom portion of said outer vessel; a rigid grate spanning the interior of said outer vessel and rigidly secured thereto; a loose gas-permeable body of an adsorbent resting on said grate; a closed-top downwardly open inner vessel of lesser wall thickness than said outer vessel and disposed in said outer vessel and having a unitary therewith a lower edge resting freely upon said grate without attachment thereto, said inner vessel being bottomless and fully open downwardly at said edge while confining said gas-permeable body of said adsorbent resting on said grate, a free space completely surrounding said inner vessel within said outer vessel to permit lateral movement of said inner vessel relative to said grate and said outer vessel; and yieldable means including a further duct connecting said upper portion of said inner vessel to an upper portion of said outer vessel for permitting gas flow out of and into said inner vessel.
Claim 2
Dependent Claim
172 words
An adsorber for cleaning of gases comprising: a pressure retentive thick-wall outer vessel provided with a duct at a bottom portion of said outer vessel; a rigid grate spanning the interior of said outer vessel and rigidly secured thereto; a loose gas-permeable body of an adsorbent resting on said grate; a closed-top downwardly open inner vessel of lesser wall thickness than said outer vessel and disposed in said outer vessel and having a unitary therewith a lower edge resting freely upon said grate without attachment thereto, said inner vessel being bottomless and fully open downwardly at said edge while confining said gas-permeable body of said adsorbent resting on said grate, a free space completely surrounding said inner vessel within said outer vessel to permit lateral movement of said inner vessel relative to said grate and said outer vessel; and yieldable means including a further duct connecting said upper portion of said inner vessel to an upper portion of said outer vessel for permitting gas flow out of and into said inner vessel.
Claim 3
Dependent Claim
21 words
The adsorber defined in claim 1 wherein the breadth dimensions of the outer and inner vessels are greater than their heights.
Claim 4
Dependent Claim
42 words
The adsorber defined in claim 1 wherein the breadth dimension of the outer vessel is greater than its height and a plurality of such inner vessels are provided within said outer vessel, each inner vessel being formed with the respective further ducts.
Claim 5
Dependent Claim
32 words
The adsorbent defined in claim 1, further comprising a layer of thermal insulation between said inner and outer vessels said layer being thinner than the space between said inner and outer vessels.
