| 摘要 |
The present invention provides a novel system and method for collecting CO2 and H2O from ambient air, using the power of a blower forcing air or another gas through a Reverse Venturi device (also called a divergent-convergent duct), to decrease the velocity of the air over a carbon capture device, and thereby increase the pressure of the unit, which results in raising of the dew point and the subsequent condensation of water in the air. This reduces the sorbent that is absorbed by the passing air stream, and increases the uptake of water vapor when a sorbent is used that attracts water. |

1. A Gas Capture System comprising:
A Gas Inlet for continuously flowing gas input; One or more Input Conduit Lines for feeding Absorbent into the system, consisting of one or more Nozzle Fluid Inlets to inject an Absorbent into said Gas Inlet; One or more Output Conduit Lines for draining Absorbent from the system, where it passes to an Absorbent Regeneration Unit before returning through said Input Conduit Lines, in a continuous process; An expanding Inlet Reverse Venturi device, connected to said Gas Inlet on one end and to a Gas Capture Chamber on the other, which results in the higher Operating Pressure within said Gas Capture Chamber; Said Gas Capture Chamber surrounding and containing a Gas Capture Device, comprised of one or more Contactor Plates where said Absorbent flows along their outer surface for the purpose of collecting a specific gas from the passing gas flow; An Absorbent Collection Surface below said Gas Capture Device to catch the Absorbent as it drips from the Contactor Plates, where it subsequently passes through said Output Conduit Lines; An Offset Expansion Chamber that maintains the higher pressure that results from the expanding Inlet Reverse Venturi, well past said Absorbent Collection Surface to maintain the saturation pressure in the gas; A contracting Outlet Venturi device, wherein the large end is connected to said Offset Expansion Chamber and the small end is a Gas Outlet, the latter with substantially the same area as the Gas Inlet; Said Gas Capture System where the area of the Gas Inlet is proportioned to the large area of the Inlet Reverse Venturi device such that the pressure increase across the device raises the Dew Point of the passing gas substantially equal to or above the temperature of the incoming gas. |
