Portable carbon dioxide absorption system
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.
1. A portable carbon dioxide (CO 2 ) absorption device comprising:
a housing defining an inlet and an outlet;
a blower in fluid communication with the inlet, wherein the blower is disposed within the housing and draws air into the housing through the inlet;
a manifold system in fluid communication with the blower, 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 received from the blower by expanding a control volume traversing the portable carbon dioxide absorption device;
a carbon-dioxide absorbing apparatus disposed within the housing, the carbon-dioxide absorbing apparatus in fluid communication with the expansion chamber and the outlet, wherein the carbon-dioxide absorbing apparatus absorbs carbon-dioxide from the air exiting the expansion chamber of the manifold housing; and
a power supply disposed within the housing and in electrical communication with the blower.
2. The portable carbon dioxide absorption device of claim 1 , wherein the blower generates a positive pressure within the portable carbon dioxide absorption device to pull air into the inlet and push the air through the expansion chamber of the manifold housing and the carbon-dioxide absorbing apparatus.
3. The portable carbon dioxide absorption device of claim 1 , further comprising:
a control system disposed within the housing and operatively engaged to the power supply and the blower, wherein the control system operates the blower to generate a desired airflow rate.
4. The portable carbon dioxide absorption device of claim 3 , 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 apparatus,
wherein the sensor is in communication with the control system to monitor an environmental concentration of CO 2 proximal to the sensor, wherein the control system receives data from the sensor to automatically operate the blower in such a manner to maintain environmental CO 2 concentration below a desired threshold.
5. The portable carbon dioxide absorption device of claim 1 , wherein the power supply includes a rechargeable battery.
6. The portable carbon dioxide absorption device of claim 5 , wherein the outlet has an outlet width greater than an inlet width of the inlet.
7. The portable carbon dioxide absorption device of claim 5 , wherein at least one of the inlet or the outlet comprises a screen or other vented covering.
8. The portable carbon dioxide absorption device of claim 1 , wherein the carbon-dioxide absorbing apparatus further comprises a CO 2 absorbing material.
9. The portable carbon dioxide absorption device of claim 8 , wherein the CO 2 absorbing material comprises one or more derivatives of ammonia.
10. The portable carbon dioxide absorption device of claim 9 , wherein the one or more derivatives of ammonia is monoethanolamine.
11. The portable carbon dioxide absorption device of claim 8 , wherein the CO 2 absorbing material is provided as a solid, semi-solid, or liquid composition.
12. The portable carbon dioxide absorption device of claim 1 , wherein the portable carbon-dioxide absorption device operates at a flow rate in a range between 20 to 60 cubic feet per minute.
13. The portable carbon dioxide absorption device of claim 1 , further comprising one or more displays, audio/visual indicators, or combinations thereof.
14. The portable carbon dioxide absorption device of claim 1 , wherein the carbon-dioxide absorbing apparatus absorbs approximately seven liters of CO 2 per minute.
15. A portable device for carbon dioxide absorption, comprising:
a housing defining an inlet and an outlet;
a blower disposed within the housing and in fluid communication with the inlet that draws air into the housing through the inlet;
a manifold system defining a manifold housing in fluid communication with the blower, the manifold housing comprising:
an expansion chamber disposed within the housing that filters and reduces a velocity of air received from the blower by expanding a control volume traversing the housing; and
a carbon-dioxide absorbing apparatus disposed within the housing, the carbon-dioxide absorbing apparatus in fluid communication with the expansion chamber and the outlet, wherein the carbon-dioxide absorbing apparatus absorbs carbon dioxide from air exiting the expansion chamber.
16. The portable device of claim 15 , wherein the blower generates a positive pressure within the housing to pull air into the inlet and push the air through the expansion chamber of the manifold housing and the carbon-dioxide absorbing apparatus and out of the housing.
17. The portable device of claim 15 , further comprising:
a control system disposed within the housing and operatively engaged to a power supply and the blower, wherein the control system operates the blower to generate a desired airflow rate.
18. The portable device of claim 17 , further comprising:
a sensor in operative communication with the control system that monitors an environmental concentration of CO 2 proximal to the sensor, wherein the control system receives data from the sensor to automatically operate the blower in such a manner to maintain environmental CO 2 concentration below a predetermined threshold.
