The present invention relates to oxygen dissolution, and more particularly, is installed in a fresh water supply pipe drained in a desalination tank such as aquaculture farm, and dissolved by extending the residence time of oxygen in water due to the stirring of oxygen and water supplied into the water. The present invention relates to an oxygen dissolving device capable of supplying a fresh water tank with an increased amount of dissolved oxygen (DO).

In general, water used in aquaculture farms requires 6 to 10 PPM of dissolved oxygen required for fish to be kept, and in order to maintain it continuously, a constant amount of oxygen is supplied into the water.

That is, the method of dissolving oxygen supplied into the water is a method of infiltrating the air stone directly into the fresh water tank and aeration, and connecting the oxygen supply hose to a fresh water supply pipe or an intermediate system device that drains the fresh water into the fresh water tank and dissolves it. It is becoming.

However, the oxygen dissolving method using the above-mentioned air stone dissolves for a very short time in which only a part of oxygen stays in water, and the remaining large amount of oxygen floats on the surface of the water to evaporate. The dissolved oxygen in the water away from the water is very low, so the efficiency of dissolving oxygen is extremely low, and it is very difficult to control the solubility of oxygen in the freshwater tank, and the method of dissolving oxygen by connecting an oxygen hose to the freshwater supply pipe described above is According to the piping structure of the installed freshwater supply pipe, the difference in the dissolution efficiency of oxygen is greatly generated, and if the oxygen supply amount is increased to increase the dissolution efficiency of oxygen, the cost of maintaining the farm is increased by increasing the oxygen consumption.

Accordingly, it is an object of the present invention to provide an oxygen dissolver which is installed in a fresh water supply pipe to increase the dissolution time of oxygen by extending the residence time of oxygen supplied into the water by an oxygen dissolver for stirring oxygen and water.

Another object of the present invention is to provide an oxygen dissolver which can significantly reduce the cost of maintaining the farm by reducing the oxygen consumption by increasing the oxygen dissolution efficiency of water supplied to the fresh water tank.
