IMPROVED METHOD AND DEVICE FOR ENRICHING OXYGEN

摘要

PURPOSE: To provide a device for introducing oxygen from air as oxygen resource into a liquid, in which additional oxygen is added independent of airflow whereby the oxygen content obtained in the liquid is significantly higher than in the case that same amount of additional oxygen is combined with the feed air flow. CONSTITUTION: A liquid is kept in a mixing vessel 10 and a feed air is jetted in the form of bubble from an air jet point 13 into the liquid for dissolving oxygen in the liquid and/or reaction. An additional oxygen is jetted into the liquid independent of the feed air from additional oxygen jet point 19 isolated from surroundings of the air jet point 13 so as to minimize the mixture of the additional oxygen and the air bubble in the liquid. As a result, the content of oxygen in the liquid is significantly higher than the content of oxygen obtained when the same amount of oxygen is jetted into the liquid and combined with the feed air flow.
