Abstract

An apparatus for cleaning air includes a housing having a chamber. The scrubber includes a carbon dioxide scrubber layer disposed in the chamber which claims carbon dioxide from air passing through the scrubber layer. The scrubber includes a forcing element which draws the air into the scrubber and forces the air through the scrubber layer which is powered without any electricity. A system for supporting a breathable environment for users. The system includes an enclosure. The system includes an air scrubber disposed in the enclosure which cleans carbon dioxide from air in the enclosure that is powered without any electricity. A method for cleaning carbon dioxide from air. The method includes the steps of flowing compressed air through a fluid driven motor to operate the motor without any electricity. There is the step of rotating a fan with the operating motor. There is the step of drawing air into a chamber of a housing with the fan blowing the air through a carbon dioxide scrubber layer of soda lime in the chamber, which scrubs the air of carbon dioxide, and out through an opening in the chamber above the layer. A cartridge for a scrubber.

Claims (38)

1. An apparatus for cleaning air comprising:

a housing having a chamber;

a carbon dioxide scrubber layer of particles of soda lime disposed in the chamber which cleans carbon dioxide from air passing through the scrubber layer, the layer having a plurality of cartridges having the particles of soda lime, each cartridge having a cartridge housing having a cartridge chamber disposed within the housing, and a porous top and opposing porous bottom with the cartridge chamber disposed between the top and the bottom; and

a forcing element which draws the air into the scrubber and forces the air through the scrubber layer which is powered without any electricity, the forcing element includes a fan, the forcing element includes a fluid powered motor mechanically engaged with the fan to operate the fan which draws the air into the chamber and forces the air through the layer, the forcing element includes a valve in fluid connection with the motor through which fluid is provided to the motor to operate the motor, the valve includes a compressed air port which receives a flow of compressed air.

2. An apparatus as described in claim 1 wherein the valve includes a compressed oxygen port which receives a flow of compressed oxygen, the valve combining the compressed air flow and the compressed oxygen flow and directing it to the motor.

3. An apparatus as described in claim 2 wherein the valve is adjustable to control the flow of compressed oxygen.

4. An apparatus as described in claim 3 wherein the valve uses only fluid to operate.

5. An apparatus as described in claim 4 wherein the fan is attached to a side wall of the housing at a hole in the side wall.

6. An apparatus as described in claim 5 wherein the motor has an outlet port through which the compressed air and compressed oxygen flows into the chamber after flowing through the motor to operate the motor.

7. An apparatus as described in claim 6 wherein the housing has a top with an opening through which the air that has passed through the layer flows out of the housing.

8. An apparatus as described in claim 7 wherein the opening of the housing has a screen.

9. An apparatus as described in claim 8 wherein the scrubber layer includes a platform disposed in the chamber upon which the soda lime is disposed.

10. A method for cleaning carbon dioxide from air comprising the steps of:

flowing compressed air and compressed oxygen through a fluid driven motor to operate the motor without any electricity, the flowing step includes the step of connecting a compressed air tank to a compressed air line connected to a valve connected to the motor;

rotating a fan with the operating motor; and

drawing air into a chamber of a housing with the fan blowing the air through a carbon dioxide scrubber layer of particles of soda lime in the chamber, which scrubs the air of carbon dioxide, and out through an opening in the chamber above the layer.

11. A method as described in claim 10 including the step of flowing the compressed air and compressed oxygen into the chamber after it flows through the motor to operate the motor.

12. A method as described in claim 11 wherein the flowing step includes the step of connecting a compressed oxygen tank to a compressed oxygen line connected to the valve connected to a gas line to the motor.

13. A method as described in claim 12 wherein the flowing step includes the step of combining the compressed air from the compressed air line and the compressed oxygen from the compressed oxygen line together with the valve and providing the compressed air and the compressed oxygen together to the motor.

14. A method as described in claim 13 including the step of placing the housing into an enclosure.

15. An apparatus for cleaning air, comprising:

a housing, the housing defining a chamber;

a scrubber layer disposed within the chamber, the scrubber layer containing particles of a CO 2 scrubbing material; and

a forcing element which draws ambient air through the housing into the chamber and forces the air through the scrubber layer within the chamber, wherein the forcing element comprises a fan that is driven by a motor powered by a combined flow of compressed air and compressed oxygen.

16. The apparatus of claim 15 , wherein the forcing element further comprises a valve that combines a flow of compressed air and a flow of compressed oxygen.

17. The apparatus of claim 16 , wherein the valve is capable of combining the flow of compressed air and the flow of compressed oxygen in variable ratios.

18. The apparatus of claim 17 , wherein the rate of flow of compressed oxygen is user-adjustable and the rate of flow of compressed air is fixed.

19. The apparatus of any one of claims 15 - 18 , wherein the forcing element further comprises an outlet port through which the combined flow of compressed air and compressed oxygen exits the forcing element after powering the fan motor.

20. The apparatus of claim 19 , wherein the outlet port is positioned to allow the combined flow of compressed air and compressed oxygen that exits the forcing element to mix with air within the chamber before the air is forced through the scrubber layer.

21. The apparatus of any one of claims 15 - 18 , wherein the particles of CO 2 scrubbing material are disposed within one or more cartridges.

22. The apparatus of claim 19 , wherein the particles of CO 2 scrubbing material are disposed within one or more cartridges.

23. The apparatus of claim 20 , wherein the particles of CO 2 scrubbing material are disposed within one or more cartridges.

24. The apparatus of any one of claims 15 - 18 , wherein the CO 2 scrubbing material is soda lime.

25. The apparatus of claim 19 , wherein the CO 2 scrubbing material is soda lime.

26. The apparatus of claim 20 , wherein the CO 2 scrubbing material is soda lime.

27. The apparatus of claim 21 , wherein the CO 2 scrubbing material is soda lime.

28. The apparatus of claim 22 , wherein the CO 2 scrubbing material is soda lime.

29. The apparatus of claim 23 , wherein the CO 2 scrubbing material is soda lime.
