<p>There is disclosed a device for dissolving a poorly soluble gas in a liquid, especially for aerating water, a device which comprises two parallel pipes fitted one inside the other, an annular throttling zone at the upper end of the inner pipe for reducing the pressure of the liquid, means for feeding the gas into the throttling zone for dissolving the gas in the liquid, and an inlet and outlet for the liquid. In this device the throttling zone has been fitted in the annular space between the pipes fitted one inside the other, while the inner pipe is connected to the inlet for the liquid, and pumping means has been provided in the inner pipe for creating a sufficient surface level difference between the inside and the outside of the device in order to cause the liquid to flow through the annular throttling zone.</p> |
