Device and method for degassing aqueous media

摘要

A device for degassing aqueous media has a first container containing medium to be degassed. A first line connects the first container to a degassing module and a second line connects the degassing module to a second container for receiving the degassed medium. A first non-return valve in the first line prevents backflow from the degassing module to the first container. A hydrophilic membrane in the second line prevents the passage of gas, and a branch between the degassing module and the hydrophilic membrane has a hydrophobic degassing filter for letting out gas. A third line is connected to the first line between the first container and the first non-return valve and to the second line between the second container and the hydrophilic membrane. A second non-return valve in the third line between the first non-return valve and the hydrophilic membrane prevents a flow towards the second container.

主权项

1. A device (1) for degassing aqueous media, comprising:
a first container (2) containing the medium to be degassed, a degassing module (4) connected via a first line (9) to the first container (2), a second container (7) for receiving the degassed medium connected via a second line (10) to the degassing module (4), a first non-return valve (3) in the first line (9) for preventing backflow from the degassing module (4) to the first container (2), a hydrophilic membrane (5, 5′) arranged in the second line (10) for preventing passage of gas, a branch comprising a hydrophobic degassing filter (24, 24′) arranged between the degassing module (4) and the hydrophilic membrane (5) for letting out gas, a third line (11) connected to the first line (9) between the first container (2) and the first non-return valve (3) and connected to the second line (10) between the second container (7) and the hydrophilic membrane (5), and a second non-return valve (6) arranged in the third line (11), between the first non-return valve (3) and the hydrophilic membrane (5) for preventing a flow toward the second container (7).
