PROCESS AND APPARATUS FOR INTRODUCTION OF GAS INTO AND DEGASSING OF LIQUIDS, IN PARTICULAR IN BIOTECHNOLOGY AND ESPECIALLY OF CELL CULTURES

摘要

The present invention is a gas exchange any type (tubes, cylinders, etc.), the type of one or more of the submerged membrane that the membrane area using an area going generate a rotational vibration motion in the liquid, liquid, liquid will in particular to a method and apparatus for the generation of a particular cell culture Four inorganic gas to water in the biotechnology, which focuses on covering to solve the problem. Figure 1 shows an example of such an arrangement and movement schematically, if the membrane area is formed by a film tube (1) which is arranged at right angles to the vertical in the direction of rotation (3) on the rotor shaft (2) The. In the case of a rotational vibration motion, the membrane area at first, and movement in one rotation direction, the motion can be configured in any way. An example is the acceleration up to a certain area in a certain angular velocity and the film, after the film is in the area of movement for a certain period of time, the angular velocity. Then, just put a brake block the area until the area is constant deceleration to stop. Then, after a predetermined stop time, if appropriate, the membrane area is the motion in the other rotational direction. This movement may be a mirror image of the already-described movement, or may be configured differently.
