ABSTRACT:
The invention relates to a gas injection or aeration device of the kind which is adapted to be immersed in a liquid and supplied with gas under pressure so that the gas emerges through diffusion nozzles of the device as a large quantity of small bubbles to form a gas/liquid mixture. According to the invention the diffusion nozzles are disposed in an upwardly extending bore of an open ended conduit submerged in the liquid. The nozzles are located between 20 and 100 centimeters below the surface of the liquid and at least 20 centimeters below the upper surface of the conduit. The nozzles are disposed in a region where the bore of the conduit is restricted to an area which is between one sixth and one twelfth of the area of the remainder of the conduit bore above the restricted region. The diffusion nozzles are constituted by holes formed laterally of at least two pipes which extend transversely across the bore of the conduit, and the aforementioned restricted area of the bore comprises at least two elongate passages defined at least in part by the said pipes. According to a characteristic feature of the invention the diffusion nozzles open directly into these passages and the holes constituting the diffusion nozzles of the pipes have diameters not exceeding 10 millimeters while the width of the passages does not exceed four times the diameter of the holes constituting the diffusion nozzles in the pipes.
