Abstract

A sorbent cartridge retention frame configured for use in an air scrubbing system comprising a first inlet side, a second outlet side, a plurality of compartments each configured to hold a solid-sorbent material, a plurality of respective walls arranged to form and separate the plurality of compartments, a first permeable membrane arranged to cover the first inlet side, a second permeable membrane arranged to cover the second outlet side. The first and/or second permeable membrane are configured for affixation to respective ends of the walls through a process of melting and solidification of the wall material such that wall material bonds with the membrane material.

First claim

The invention claimed is:

1. A sorbent cartridge retention frame configured for use in an air scrubbing system comprising:
a first inlet side;
a second outlet side;
a plurality of compartments each configured to hold a solid-sorbent material;
a plurality of respective walls arranged to form and separate the plurality of compartments;
a first permeable membrane arranged to cover the first inlet side;
a second permeable membrane arranged to cover the second outlet side;
wherein:
the first and/or second permeable membrane are configured for affixation to respective ends of the walls through a process of melting and solidification of the wall and/or membrane material such that the membrane and wall bond together, and
at least one of the ends of the walls is beveled, sloped, and/or configured with multiple slopes to facilitate filling of the compartments with sorbent material and/or a process of attaching the first and/or second membranes to the frame.

2. The frame of claim 1 , wherein at least one of the ends of the walls include a triangular profile.

3. The frame of claim 1 , wherein a stream of air comprising adsorbates enters the frame via the first inlet side and comes in contact with the sorbent material, to which the adsorbates adhere.

4. A sorbent cartridge manufacturing method comprising:
providing a frame comprising a first side, a second side, a plurality of compartments each configured to hold sorbent material, a plurality of respective walls arranged to form and separate the plurality of compartments, wherein a first end of each wall is arranged on the first side and a second end of each wall is arranged on the second side;
arranging a first air and/or fluid permeable membrane on the first side,
melting at least a portion of the first end of the plurality of the walls, wherein portions of the first permeable membrane lying adjacent the melted portion of the first end bond with the melted portion thereby affixing the first permeable membrane thereto;
filling the plurality of the compartments with sorbent material;
arranging a second air and/or fluid permeable membrane on the second side, and
melting at least a portion of the second end of the plurality of the walls, wherein portions of the second permeable membrane lying adjacent the melted portion of the second end are configured to bond with the melted portion thereby affixing the second permeable membrane thereto,
wherein one or more edges of the second end of the plurality of walls are beveled, sloped, multiply sloped, and/or triangular in profile.

5. The method of claim 4 , wherein melting is facilitated by applying heat, radiation or ultrasonic power.

6. The method of claim 5 , wherein application of heat comprises applying pressure to the first and/or second ends of the plurality of walls via a plate for a predetermined period of time.

7. The method of claim 4 , wherein said filling comprises filling the plurality of the compartments with sorbent material to full capacity from the first membrane to the second membrane.

8. The method of claim 4 , wherein the melting is performed at a temperature ranging from the Glass Transition Temperature (Tg) to the Melting temperature (Tm) of the wall material.

9. A sorbent cartridge manufacturing method comprising:
providing a frame comprising a first side, a second side, a plurality of compartments each configured to hold sorbent material, a plurality of respective walls arranged to form and separate the plurality of compartments, wherein a first end of each wall is arranged on the first side and a second end of each wall is arranged on the second side;
arranging a first air and/or fluid permeable membrane on the first side,
melting at least a portion of the first end of the plurality of the walls, wherein portions of the first permeable membrane lying adjacent the melted portion of the first end bond with the melted portion thereby affixing the first permeable membrane thereto;
filling the plurality of the compartments with sorbent material;
arranging a second air and/or fluid permeable membrane on the second side, and
melting at least a portion of the second end of the plurality of the walls, wherein portions of the second permeable membrane lying adjacent the melted portion of the second end are configured to bond with the melted portion thereby affixing the second permeable membrane thereto,
wherein
melting is facilitated by applying heat, radiation or ultrasonic power,
application of heat comprises applying pressure to the first and/or second ends of the plurality of walls via a plate for a predetermined period of time, and
the plate is configured with apertures, at least a portion of which correspond with the one and/or another of the plurality of compartments.

10. A sorbent cartridge sealing system, the cartridge comprising a frame including a first side, a second side, a plurality of compartments each configured to hold sorbent material, a plurality of respective walls arranged to form and separate the plurality of compartments, wherein a first end of each wall is arranged on the first side and a second end of each wall is arranged on the second side, the cartridge further comprising a first air and/or fluid permeable membrane arranged on the first side and a second air and/or fluid permeable membrane arranged on the second side, the system comprising:
a platform configured to support the cartridge frame, and
at least one plate configured to apply force to the first end and/or the second ends of the plurality of walls such that at least a portion of the first and/or second ends melt and bond with the corresponding portions of the first and/or second membrane lying adjacent thereto to affix the first and/or second membrane to the frame,
wherein the at least one plate is further configured with one or more apertures at least a portion of each align with respective compartments of the frame.

11. The system of claim 10 , wherein the apertures are configured to vent vapor and/or hot gas emanating from the sorbent material during the affixing process.

12. A sorbent cartridge sealing system, the cartridge comprising a frame including a first side, a second side, a plurality of compartments each configured to hold sorbent material, a plurality of respective walls arranged to form and separate the plurality of compartments, wherein a first end of each wall is arranged on the first side and a second end of each wall is arranged on the second side, the cartridge further comprising a first air and/or fluid permeable membrane arranged on the first side and a second air and/or fluid permeable membrane arranged on the second side, the system comprising:
a platform configured to support the cartridge frame, and
at least one plate configured to apply force to the first end and/or the second ends of the plurality of walls such that at least a portion of the first and/or second ends melt and bond with the corresponding portions of the first and/or second membrane lying adjacent thereto to affix the first and/or second membrane to the frame,
wherein the platform is further configured with one or more apertures at least a portion of each align with respective compartments of the frame.

13. The system of claim 12 , wherein the apertures are configured to vent vapor and/or hot gas emanating from the sorbent material during the affixing process.
