Gas adsorber cell test sampler

A gas adsorber cell for use in high efficiency gas cleaning systems and the like and having provision for obtaining a representative and undisturbed sample of the adsorbent material to permit periodic testing of the efficacy of the adsorbent material, said adsorbent cell comprising

• an enclosure including first and second substantially flat, perforated sheets disposed in spaced apart, parallel relationship, said enclosure being adapted to receive an adsorbent material between said sheets such that a gas may be passed transversely through the sheets and adsorbent material,
• a first aperture in said first sheet and a second aperture in said second sheet, said apertures being transversely aligned to define a transverse axis lying perpendicular to said first and second sheets,
• a receptacle mounted within said enclosure and extending between said first and second apertures, said receptacle comprising
• a. a side wall disposed about said transverse axis and defining a forward end adjacent said first aperture and a bottom end adjacent said second aperture, and
• b. an imperforate flat bottom flange fixedly connected to said bottom end of said side wall and lying perpendicular to said transverse axis, said bottom flange including an outer edge positioned radially outside of said side wall of said receptacle to thereby define an outer flange portion overlying that portion of said second sheet immediately surrounding said second aperture and adapted to prevent the gas from channeling between the adsorbent material in said enclosure and said receptacle side wall, and said bottom flange further including an inner opening positioned radially within said side wall of said receptacle to define an inner flange portion,
• a sample holder adapted to be filled with an adsorbent material and comprising a side wall, a perforated top end wall, and a perforated bottom end wall spaced from and parallel to said top end wall, said sample holder being configured to permit the same to be received within said receptacle in an operative position along said transverse axis and with one of said top and bottom end walls supported by said inner flange portion of said receptacle such that said top and bottom end walls are positioned parallel to said first and second perforated sheets, and
• means for removably mounting said sample holder within said receptacle in said operative position, whereby a representative portion of the gas passing transversely through the adsorber cell passes through said sample holder, and the holder may be removed to permit the testing of the adsorbent material carried therein.

• an enclosure including first and second substantially flat, perforated sheets disposed in spaced apart, parallel relationship, said enclosure being adapted to receive an adsorbent material between said sheets such that a gas may be passed transversely through the sheets and adsorbent material,
• a first circular aperture in said first sheet and a second circular aperture in said second sheet, said apertures being transversely aligned to define a transverse axis lying perpendicular to said first and second sheets,
• a receptacle mounted within said enclosure and extending between said first and second apertures, said receptacle comprising
• a. a cylindrical side wall disposed coaxially about said transverse axis and defining a forward end adjacent said first aperture and a bottom end adjacent said second aperture,
• b. an imperforate circular flat bottom flange fixedly connected to said bottom end of said side wall and lying perpendicular to said transverse axis, said bottom flange including a circular outer edge coaxial with said transverse axis and having a diameter greater than that of said cylindrical side wall of said receptacle to thereby define an outer flange portion overlying that portion of said second sheet immediately surrounding said second aperture, and said bottom flange including a circular inner opening coaxial with said transverse axis and having a diameter less than said cylindrical side wall of said receptacle to define an inner flange portion, and
• c. an imperforate circular flat top flange fixedly connected to said forward end of said receptacle side wall and lying perpendicular to said transverse axis, said top flange including a circular outer edge coaxial with said transverse axis and having a diameter greater than that of said cylindrical side wall of said receptacle to thereby define an outer flange portion overlying that portion of said first sheet immediately surrounding said first aperture, and said top flange including a circular inner opening coaxial with said transverse axis and having a diameter substantially corresponding to that of said receptacle side wall,
• a sample holder adapted to be filled with an adsorbent material and comprising a cylindrical side wall, a perforated top end wall, and a perforated bottom end wall spaced from and parallel to said top end wall, said sample holder side wall having a diameter somewhat less than the diameter of said receptacle side wall such that said sample holder may be inserted into said receptacle along said transverse axis and through said top flange to thereby assume an operative position wherein one of said top and bottom end walls is supported by said inner flange portion of said receptacle and such that said top and bottom end walls are positioned parallel to said first and second perforated sheets, and
• means for removably mounting said sample holder within said receptacle in said operative position, whereby a representative portion of the gas passing transversely through the adsorber cell passes through said sample holder, and the holder may be removed to permit the testing of the adsorbent material carried therein.
