AERATOR Russian patent published in 1995 - IPC

FIELD: water oxygenation; fishery. SUBSTANCE: device has two-contour jet pump ejector in which water supplied under pressure into a sleeve is brought to converging tube of the first contour where air is drawn in the volume fully soluble in the supplied water. Further, in passing through converging tube of the second contour, water draws in additional quantity of air making water-and-air emulsion in mixer. In passing through the aerator the water becomes fully saturated with air oxygen reaching the limit concentration at given water temperature. Aerated water with excessive air contents enters into the water mass from tubes through repulsing distributor spreader. Improved solubility of the sucked air in water is achieved due to its curling in passing through the tangential windows of the casing and inclined cantilevers of the converging tube of the first contour. Additional effect of water mass aeration in water pool is achieved due to bubbling rise of excessive air of the water-and-gas emulsion from the level of repulsing distributor to the level of the water pull surface. EFFECT: improved quality of water oxygenation. 3 cl, 4 dwg
