Collecting a gaseous pollutant from air
An apparatus for collecting a gaseous pollutant from air may comprise multiple vertical panel-beds each containing a solid sorbent; a fan to pass the air through the multiple vertical panel-beds and over the solid sorbent; an outlet gate configured to release the solid sorbent from the multiple vertical panel-beds after the fan passes the air over the solid sorbent; a regeneration vessel configured to regenerate the released solid sorbent by recovering the gaseous pollutant from the released solid sorbent; and a conveyor configured to return the regenerated solid sorbent to the multiple vertical panel-beds.
1. An apparatus for collecting a gaseous pollutant from air, the apparatus comprising:
a duct having a duct inlet in fluid communication with the air;
an inlet pipe in fluid communication with (1) the duct and (2) an inlet manifold via multiple portions of the inlet manifold;
multiple vertical panel-beds each containing a solid sorbent wherein the multiple vertical panel-beds are separately in fluid communication with the inlet manifold; and
a fan configured to pass the air through the duct, the inlet pipe, and the inlet manifold into the multiple vertical panel-beds and over the solid sorbent.
2. The apparatus of claim 1 , further comprising:
an outlet manifold separately in fluid communication with the multiple vertical panel-beds to allow filtered air to exit the multiple vertical panel-beds after the fan passes the air through the duct and the inlet manifold into multiple vertical panel-bed chambers and over the solid sorbent.
3. The apparatus of claim 2 , further comprising:
a regeneration vessel configured to regenerate a released solid sorbent by recovering the gaseous pollutant from the released solid sorbent.
4. The apparatus of claim 3 , further comprising:
a conveyor configured to return the regenerated solid sorbent to the multiple vertical panel-beds.
5. The apparatus of claim 1 , wherein the solid sorbent comprises at least one of:
a zeolite;
activated carbon;
an ion exchange resins;
a metal organic framework;
silica;
polymers;
amine functionalized sorbent variations;
Prussian blue; and
other natural organic, inorganic, or synthetic sorbents.
6. The apparatus of claim 1 , wherein the gaseous pollutant comprises at least one of:
ammonia;
methane;
hydrogen sulfide;
nitrous oxides;
carbon monoxide; and
carbon dioxide.
7. The apparatus of claim 1 , wherein each of the multiple vertical panel-beds comprises:
a porous sheet configured to contain the solid sorbent and non-porous sheets to enclose the vertical panel-beds.
8. The apparatus of claim 2 , further comprising:
an actuator configured to operate an outlet gate configured to release the solid sorbent from the multiple vertical panel-beds after the fan passes the air through the duct and the inlet manifold into multiple vertical panel-bed chambers and over the solid sorbent.
9. The apparatus of claim 2 , further comprising:
a collection chamber configured to hold the solid sorbent after release of the solid sorbent from the multiple vertical panel-beds.
10. The apparatus of claim 3 , further comprising:
a sorbent storage area configured to hold the solid sorbent after transfer of the solid sorbent from the regeneration vessel; and
an inlet gate configured to release the solid sorbent from the sorbent storage area into the multiple vertical panel-beds.
11. The apparatus of claim 10 , further comprising:
an actuator configured to operate the inlet gate.
12. The apparatus of claim 1 , further comprising:
a particulate matter filtration device configured to filter particulates from the air prior to the air passing over the solid sorbent.
13. The apparatus of claim 1 , further comprising:
a scraper configured to effect removal of the solid sorbent from the multiple vertical panel-beds.
14. The apparatus of claim 1 , further comprising:
a screen configured to prevent large particulate matter from entering the duct inlet.
15. The apparatus of claim 1 , wherein:
wherein two or more of the vertical panel-beds contain different solid sorbents to adsorb different gaseous pollutants.
16. The apparatus of claim 1 , wherein the air enters the inlet pipe from one side of the apparatus and exits an outlet pipe on the other side of the apparatus.
17. The apparatus of claim 1 , wherein each of the multiple vertical panel-beds is enclosed on both sides by a non-porous barrier to form a vertical panel-bed chamber.
18. The apparatus of claim 1 , wherein each of the multiple vertical panel-beds is less than 1 inch thick.
19. The apparatus of claim 1 , wherein the multiple vertical panel-beds are segregated.
