Abstract

Various embodiments of a portable carbon dioxide (CO2) absorption device that may remove excess CO2 from a closed environment are disclosed herein. The absorption device is reusable and configured for many environments.

Claims (42)

1. A portable carbon dioxide absorption machine comprising:

a housing defining an inlet and an outlet;

a blower in fluid communication with the outlet and with a manifold system the blower being disposed within the housing, wherein the blower pulls air from the manifold system into the housing, and pushes the air from the housing through the outlet;

the manifold system comprising a manifold housing defining an expansion chamber; the expansion chamber disposed within the housing, wherein the expansion chamber filters and reduces a velocity of air pulled by the blower;

a carbon dioxide absorbing device disposed within the housing, the carbon dioxide absorbing device in fluid communication with the inlet and the manifold system, wherein the carbon dioxide absorbing device absorbs carbon dioxide from the air entering the inlet; and

a power supply disposed within the housing, wherein the power supply is in electrical communication with the blower.

2. The portable carbon dioxide absorption machine of claim 1 , wherein the blower generates a negative pressure to draw air external to the housing through the carbon dioxide absorbing machine and the manifold system.

3. The portable carbon dioxide absorption machine of claim 1 , wherein the inlet of the housing has an inlet width greater than an outlet width of the outlet of the housing.

4. The portable carbon dioxide absorption machine of claim 1 , wherein an exterior opening of the outlet comprises at least one of a screen coupled to an inner diameter of the exterior opening of the outlet, a mesh coupled to the inner diameter of the exterior opening of the outlet, or a plurality of holes defined by the housing.

5. The portable carbon dioxide absorption machine of claim 1 , wherein the carbon dioxide absorbing device comprises a carbon dioxide absorbing material that absorbs the carbon dioxide from the air entering the inlet.

6. The portable carbon dioxide absorption machine of claim 1 , wherein the carbon dioxide absorbing device is configured to be removed and replaced from the housing.

7. The portable carbon dioxide absorption machine of claim 1 , wherein the carbon dioxide absorbing device houses a carbon dioxide absorbent in a removable canister cartridge.

8. The portable carbon dioxide absorption machine of claim 1 , wherein the carbon dioxide absorbing device houses a carbon dioxide absorbent in a refillable canister.

9. The portable carbon dioxide absorption machine of claim 1 , wherein the manifold system is configured to include a plurality of baffles.

10. The portable carbon dioxide absorption machine of claim 1 , wherein the manifold system is configured to include cyclonic separation.

11. The portable carbon dioxide absorption machine of claim 1 , further comprising:

a sensor disposed within or proximal to at least one of the inlet, the outlet, the housing, the blower, the manifold system, or the carbon dioxide absorbing device, where the sensor monitors an environmental concentration of CO2 proximal to the sensor.

12. The portable carbon dioxide absorption machine of claim 1 , wherein the portable carbon dioxide absorption machine is operable to be operated remotely.

13. The portable carbon dioxide absorption machine of claim 1 , further comprising a vented covering engaged to an exterior opening of the outlet and the inlet.

14. A method for automatically reducing a concentration of carbon dioxide (CO 2 ) in an enclosed environment using a portable carbon dioxide absorption machine, the method comprising:

providing a portable carbon dioxide absorption machine in an enclosed environment, the portable carbon dioxide absorption machine comprising:

an housing defining an inlet and an outlet,

a blower in fluid communication with the outlet and with a manifold system, the blower being disposed within the housing, wherein the blower pulls air from the manifold system, and pushes air from the housing through the outlet,

the manifold system comprising a manifold housing defining an expansion chamber, the expansion chamber, disposed within the housing, wherein the expansion chamber filters and reduces a velocity of air pulled by the blower, and

a carbon dioxide absorbing device disposed within the housing, the carbon dioxide absorbing device in fluid communication with the inlet and the manifold system, wherein the carbon dioxide absorbing device absorbs carbon dioxide from the air entering the inlet;

continuously measuring an environmental concentration level of CO 2 in the enclosed environment using a sensor in communication with a control system of the portable carbon dioxide absorption machine;

determining, at the control system if the environmental concentration level of CO 2 exceeds a predetermined threshold;

continuously or intermittently operating the blower of the portable carbon dioxide absorption machine to draw the air into the portable carbon dioxide absorption machine such that the concentration of CO 2 emitted from the portable carbon dioxide absorption machine is less than the environmental concentration level of CO 2 ; and

ceasing operation of the blower when the environmental concentration level of CO 2 falls below the predetermined threshold.

15. The method of claim 14 , further comprising:

filtering the air entering the portable carbon dioxide absorption machine to capture and remove dust or other particulates from the enclosed environment.

16. The method of claim 14 , further comprising:

setting the predetermined threshold based upon a measurement of a volume of the enclosed environment and an anticipated increase in concentration levels of CO 2 within the enclosed environment.

17. The method of claim 14 , wherein operation of the blower is ceased automatically.

18. A method of manufacturing a portable carbon dioxide absorption machine comprising:

providing a housing including an inlet and an outlet;

disposing a blower within the housing such that the blower is in fluid communication with the outlet and with a manifold system, wherein the blower pulls air from the manifold system and pushes air from the housing through the outlet;

configuring the manifold system to comprise a manifold housing defining an expansion chamber, wherein the expansion chamber is disposed within the housing and filters the air and reduces a velocity of the air pulled in by the blower;

disposing a carbon dioxide absorbing device within the housing, the carbon dioxide absorbing device in fluid communication with the inlet and the manifold system, wherein the carbon dioxide absorbing device absorbs carbon dioxide from the air entering the inlet; and

disposing a power supply within the housing, wherein the power supply is in electrical communication with the blower.

19. The method of claim 18 , further comprising configuring an exterior opening of the outlet to comprise at least one of a screen coupled to an inner diameter of the exterior opening of the outlet, a mesh coupled to the inner diameter of the exterior opening of the outlet, or a plurality of holes defined by the housing.

20. The method of claim 18 , further comprising disposing within the carbon dioxide absorbing device a carbon dioxide absorbing material that absorbs the carbon dioxide from the air entering the inlet.
