APPARATUS FOR GENERATING MICRO BUBBLE AND LAKE PURIFICATION APPARATUS HAVING THE SAME

摘要

The present invention relates to an ultramicro bubble generator which generates ultramicro bubbles at normal pressure and supplies the ultramicro bubbles into the lake water to purify the lake water, and a lake purification system having the ultramicro bubble generator. The ultramicro bubble generator by the present invention comprises: a case (13) having an inflow space (14) and a suction hole; a water pump (18) installed inside the case (13); a vacuum ejector (26) having a flow passage (27) and a suction passage (28), wherein the flow passage (27) is connected a connection passage arranged at the case (13) and the suction passage (28) is connected sidewise to the flow passage (27) so as to generate negative pressure by the flow of the water passing the flow passage; an air supply pipe (29) combined to the vacuum ejector (26) to be connected with the suction passage (28); and a disperser (31). The disperser (31) has: a spray head (34) having a discharge outlet (35) which is connected with the flow passage (27) to spray a mixed fluid of water and air outside, wherein the mixed fluid of water and air is made as water and air are mixed in the vacuum ejector (26); a collision plate (37) installed apart from the discharge outlet (35) in the front of the discharge outlet (35); and a spray nozzle (36) for spraying ultramicro bubbles and water onto the outside of the spray head (34), wherein the ultramicro bubbles are generated as the mixed fluid of water and air collides with the collision plate (37) after being discharged from the discharge outlet (35).
