Abstract
Abstract The invention concerns apparatus for purifying air and other gas laden with an adsorbate using active charcoal or other adsorbent in a tank comprising an inlet chamber, an adsorbent chamber and an outlet chamber arranged juxtaposed in side-by-side arrangement and extending from one end of the tank to the other with end cover closures containing the connection zones for the inlet and outlet of the gas and the adsorbent substance. The tank comprises a plurality of sections connectable to one another by flanged connections so that a tank of any length can be made to suit a desired throughput capacity. The adsorbent chamber may be vertical, inclined or zigzag. In addition to connection zones at the ends of the tank, tank sections with lateral connections may be provided intermediate the ends of the tank.

Claims Analysis
Total Claims: 18
Claim 1
Independent Claim
177 words
An apparatus operating with an adsorbent substance for purifying air or another gas laden with an adsorbate, comprising a tank having a gas inlet chamber, an adsorbent chamber and a gas outlet chamber in side-by-side juxtaposed relationship and extending from one end of the tank to the other, end face cover closures and a tank envelope enclosing the three chambers which consists of a plurality of sections connected at their end faces together by flanges, in at least one section of the tank envelope the connection zones for the inlet and outlet of gas and adsorbent substance being arranged at the end faces through apertures in inlet, outlet and adsorbent portions of said end faces comprising means defining said gas inlet, gas outlet and adsorbent chambers, respectively, and first and second porous dividing means each extending between said end faces separating said gas inlet and gas outlet chambers respectively from said adsorbent chamber for confining said adsorbate in said adsorbent chamber while allowing gas to flow therethrough from said gas inlet chamber to said gas outlet chamber.
Claim 2
Independent Claim
177 words
An apparatus operating with an adsorbent substance for purifying air or another gas laden with an adsorbate, comprising a tank having a gas inlet chamber, an adsorbent chamber and a gas outlet chamber in side-by-side juxtaposed relationship and extending from one end of the tank to the other, end face cover closures and a tank envelope enclosing the three chambers which consists of a plurality of sections connected at their end faces together by flanges, in at least one section of the tank envelope the connection zones for the inlet and outlet of gas and adsorbent substance being arranged at the end faces through apertures in inlet, outlet and adsorbent portions of said end faces comprising means defining said gas inlet, gas outlet and adsorbent chambers, respectively, and first and second porous dividing means each extending between said end faces separating said gas inlet and gas outlet chambers respectively from said adsorbent chamber for confining said adsorbate in said adsorbent chamber while allowing gas to flow therethrough from said gas inlet chamber to said gas outlet chamber.
Claim 3
Dependent Claim
18 words
An apparatus as claimed in claim 1, wherein the tank envelope is a cylinder of a rectangular cross-section.
Claim 4
Dependent Claim
44 words
An apparatus as claimed in claim 1, wherein the end face connection surfaces on all the envelope sections have the same shape and subdivision, whereby a cover or a further envelope section is selectively connectable to both end faces of all the envelope sections.
Claim 5
Dependent Claim
17 words
An apparatus as claimed in claim 3, wherein identical exchangeable connection covers are provided for both ends.
Claim 6
Dependent Claim
30 words
An apparatus as claimed in claim 1, wherein the tank is arranged upright so that the adsorbent chamber forms a substantially vertical bulk shaft extending continuously from bottom to top.
Claim 7
Dependent Claim
27 words
An apparatus as claimed in claim 1, wherein the adsorbent chamber is arranged in the tank inclined with respect to the longitudinal direction axis of the tank.
Claim 8
Dependent Claim
63 words
An apparatus as claimed in claim 6, wherein the adsorbent chamber in each envelope section adjoins the end faces of the envelope section in connection regions staggered equally but in mirror image relationship with respect to the median plane, so that a zigzag-shaped pattern of the adsorbent chamber is obtained in the case of the serial connection of a plurality of envelope sections.
Claim 9
Dependent Claim
27 words
An apparatus as claimed in claim 7, wherein both connection regions of the adsorbent chamber of an envelope section are staggered to a predetermined free minimum interval.
Claim 10
Dependent Claim
46 words
An apparatus as claimed in claim 6, which comprise envelope sections of different lengths, wherein in envelope sections of shorter length the adsorbent chamber is more steeply inclined, so that an equal stagger of its connection regions is obtained as in envelope sections of greater length.
Claim 11
Dependent Claim
54 words
An apparatus as claimed in claim 6, wherein the connection cover is provided with a wedge-shaped cover space adapted to the inclination of the adsorbent chamber, while the inflow and outflow surface is drawn into the cover space so that the effective adsorbent layer terminates with end surfaces approximately orthogonal to its boundary surfaces.
Claim 12
Dependent Claim
40 words
An apparatus as claimed in claim 1, which includes envelope sections having a lateral air pipe connection, wherein the adsorbent chamber in envelope sections having a lateral air pipe connection extends parallel to the median plane of the envelope section.
Claim 13
Dependent Claim
69 words
An apparatus as claimed in claim 1, wherein two tanks are arranged parallel and are connected to air supply pipe and discharge pipes through changeover valves, the valve chamber of which is constructed as a pipe section arranged transversely to the valve stroke axis, and is provided at both ends with connections, one for an air pipe and the other for a blind flange constructed as a sight glass.
Claim 14
Dependent Claim
45 words
An apparatus as claimed in claim 1, wherein in order to delimit the adsorbent chamber, perforated plates slidable into guideways on the inside of the envelope are provided which are provided with step bearings for the mutual bracing of perforated plates of adjacent envelope sections.
Claim 15
Dependent Claim
28 words
An apparatus as claimed in claim 13, comprising perforated plates with step bearings for the perforated plates of both the next higher and the next lower envelope section.
Claim 16
Dependent Claim
51 words
An apparatus as claimed in claim 14, wherein the perforated plate inclined with respect to the adjacent air chamber is provided with step bearings, whereas the perforated plate placed opposite in the envelope section is supported in step bearings of the perforated plates of the next higher or lower envelope section.
