A gas-liquid exchanging device includes a gas-liquid exchanging vessel (8) whose upper end is closed, a front end and a back end of the vessel are respectively connected with a gas inlet pipeline (7) and a gas outlet pipeline (6), a gas blocking plate (2) is fitted in a gas inlet end of the vessel, a liquid blocking plate (1) is fitted in a gas outlet end of the vessel, the vessel is filled with liquid, a gas flow channel formed above the liquid is communicated with the gas inlet pipeline (7) and the gas outlet pipeline (6). When the gas flow from the gas inlet pipeline (7) enters the gas-liquid exchanging vessel (8), fast gas flow is formed, and the fast gas flow brings the liquid to leave the liquid surface and spray to the space in the gas flow channel to form a liquid curtain, the gas traverses the liquid curtain and contacts with the liquid sufficiently, so as to achieve the energy exchange and the matter exchange between gas phase and liquid phase, and a part of liquid comes to the liquid blocking plate (1) and is blocked by it to form a secondary liquid curtain, the gas flow after exchanging is discharged from a gas outlet under the liquid blocking plate. |
