及び電磁弁７は開状態で使用する。A liquid such as water is sucked from the filter 2 and a gas such as air is sucked from the gas suction port 4 to the pump 1.
This gas-liquid mixture (liquid containing bubbles) is agitated and pressurized by the pump 1 and sent to the pressure container 3. Furthermore, the dissolution of gas in the liquid progresses here, and the gas that could not be completely dissolved is
The liquid accumulates in the upper part and is separated into a liquid in which a gas is sufficiently dissolved and a gas which is not completely dissolved. The gas that cannot be completely dissolved is discharged from the excess gas discharge port 5 so that the water level in the pressurizing container 3 is kept constant, and only the liquid in which air is dissolved is sent to the nozzle 9, and the pressure is reduced by the nozzle 9. It is then discharged into the liquid and the dissolved gas is deposited. At this time, the solenoid valve 8
The solenoid valve 7 is used in the open state.

げずにすべてフィルター２から吐出される。At the same time as turning off the power and stopping the pump, the solenoid valve 8
And the solenoid valve 7 is closed. Immediately after the power is turned off, the pressure in the pressure vessel 3 is still 6 to 7 kg / cm 2 . Therefore, at the same time, by closing the solenoid valves 8 and 7, respectively, the escape path for the pressure is limited to one direction. That is, only the path from the pump 1 to the filter 2 is opened. As described above, since the residual pressure of 6 to 7 kg / cm 2 remains inside the pressurized container 3, the gas trapped inside expands, so that the liquid and gas in the pipes are in operation path. On the contrary,
The filter 2 is vigorously discharged, and the filter 2 is backwashed. At this time, the check valve 6 is attached to the gas suction port 4.
Is attached, all residual pressure is discharged from the filter 2 without escaping from the air suction port 4.

為、非常に低廉である。As described above, the bubble generating apparatus of the present invention can easily backwash the filter by utilizing the residual pressure in the pressure vessel, and thus can constantly and stably generate the bubbles. Since it does not use power to run, there is no waste of energy and running cost is zero. Further, the initial cost when the present invention is carried out by utilizing the conventional apparatus is also very high because it is usually necessary only to add an electromagnetic valve between the discharge part of the pressurizing container and the nozzle for decompression and to the surplus gas discharge port. It is inexpensive.
