Abstract
The present invention relates to a microbubble generating nozzle comprising a main body with a first water inlet in the upper portion thereof and a second controlled flow air inlet in a lateral recess of the lateral wall of the main body of the nozzle, as well as a gauge that is coupled to the lower portion of said main body and that forms a separation into which ducts open through which air and water circulate through the inside of the nozzle, the air comes into contact with the water and microbubbles are formed that subsequently are dispersed throughout the inside of a water tank at a water treatment facility.
Claims4
A microbubble generating nozzle intended for being immersed in a water tank in water treatment facilities using DAF technology, comprising:
- a main body (1) with at least one first inlet (11) in the upper surface of said main body (1) and at least one second inlet (12) in the lateral wall of the main body (1),
- a first duct (4) that starts from the first inlet (11) and is intended to conduct a water stream through the inside of the main body (1),
- a second duct (5) starting from the second inlet (12) which is intended to conduct an air stream through the inside of the main body (1), said air stream previously controlled by an air adjustment valve,
- A hollow ring (6) with a diameter cross section that is located inside the main body (1) surrounding the first duct (4) and that transversely receives the second duct (5), said hollow ring (6) intended to distribute the air in an equitable manner and which in turn comprises third ducts (7) that are intended to direct the air that circulates through the hollow ring (6) in an equitable manner, and
- a gauge (8) positioned in the area below the main body (1), attached to said main body (1) by means of fixing elements and which creates a separation (9) into which the first duct (4) and the third ducts (7) open, said separation (9) intended to produce microbubbles by contact between the air and water coming from the ducts (4, 7) and expel the microbubbles into the water tank.
- wherein the separation (9) enables the nozzle to be scaled to variable operating conditions of pressure and speed of the air and water stream, said separation ranging from 0.3 to 5 millimeters.
