APPARATUS FOR GENERATING MICRO BUBBLE AND WATER TREATMENT FACILITY HAVING THE SAME

摘要

The present invention relates to an ultramicro bubble generator which is capable of purifying contaminated water by generating ultramicro bubbles at normal pressure and by supplying the ultramicro bubbles into the water, and a water treatment facility having the ultramicro bubble generator. The ultramicro bubble generator by the present invention comprises: a case (43) having an inflow space (44) and suction holes (45); an air supply pipe (53) for supplying air into the inflow space (44); a water pump (46) installed inside the case (43) to pump a mixed fluid of water and air made by mixing water and air; and a disperser (57). The disperser (57) has: a spray head (60) which has a discharge outlet connected with a connection passage (56) in the case (43) and which sprays, onto the outside of the case (43), the mixed fluid of water and air flowing along the connection passage (56); a collision plate (63) installed apart from the discharge outlet of the spray head (60) in the front of the discharge outlet; and a spray nozzle which is installed between the spray head (60) and the collision plate (63) and which sprays ultramicro bubbles and water onto the outside of the spray head (60), wherein the ultramicro bubbles are generated as the mixed fluid of water and air collides with the collision plate (63) after being discharged from the discharge outlet.
