AERATING DEVICE Russian patent published in 1999 - IPC

FIELD: natural water purification and sewage treatment. SUBSTANCE: device is intended for saturation of liquids with gas. Aerating device has air duct assembled of great number of aerating modules secured to one another tightly. Each of aerating modules includes circular dispergator and composite tubular member on which it is secured in cantilever way, horizontally, in zone of connection of tubular member parts and with which it communicates by means of compressed air. Dispergator has supporting ring with hope for passage of compressed air, axis of hole being shifted relative to axis of circular dispergator, and dispersing element which forms circular throttling member together with supporting ring. Dispergator is mounted for displacements about vertical axis of supporting ring hole and provided with appliance for fixing of it to composite tubular member. This appliance has vertical channel coaxial with hole provided in supporting ring. Flow section area of throttling member is from 0.15 to 1.0 of cross-sectional area of the vertical channel. Relation of external diameter to diameter of hole in circular dispergator is from 1.5 to 2.6. EFFECT: higher aeration efficiency. 7 cl, 5 dwg
