To provide an oxygen enriching air introduction system, where the flow rate of oxygen enriching air is adjustable.
In the oxygen enriching air introduction system, oxygen enriching air is produced by an oxygen enriching means 2 by causing negative pressures to be generated in the water flow of a pipe 6 and making it act on the oxygen enriching means 2 through an introduction pipe 1. Then, the produced oxygen enriching air is introduced into the pipe 6 from the introduction pipe 1. The system includes a flow rate adjustment means 3 to adjust the flow rate of water in the pipe 6 and at least either a sensor 4 to detect the pressure or flow rate of oxygen enriching air in the introduction pipe 1 or a sensor 5 to detect the temperature of oxygen enriching membrane 21 of oxygen enriching means 2 or its ambient temperature. The flow rate of oxygen enriching air made to enter the pipe 6 from the introduction pipe 1 is adjusted as the flow rate adjustment means 3 adjusts the flow rate of pipe 6 and changes the negative pressures taking place in the flow of pipe 6, in accordance with the pressure or flow rate of oxygen enriching air in the introduction pipe 1, or the temperature of oxygen enriching membrane 21, detected by the sensor 4, 5.
