| abstract |
In order to bring a gas and a liquid into contact with one another, for example so as to exchange, remove or add components or calorific value present in the gas and/or liquid, the liquid is guided along one or more walls which are provided with small openings, and the gas is guided into the liquid, via these openings, by allowing this liquid to flow along the walls or by moving the walls along the liquid. In order to increase the contact time between gas and liquid, the gas is guided into the liquid in a direction which essentially corresponds to the direction of movement of the liquid with respect to the wall which is provided with openings. A venturi effect is generated in the region of the openings, since subatmospheric pressure is produced at the location where the openings open into the stream of liquid. If the walls are in the form of plates, use is preferably made, in order to separate the gas flow to be discharged from one another, of a water seal which is produced if the inclined plates which are provided with openings, alternate with closed, inclined plates, project into a reservoir of liquid. |
