<p>PURPOSE:To conduct aeration uniformly and efficiently saving the energy by atomizing air sucked into water and ejecting the air radially in an aerator installed at a depth suitable to a water area. CONSTITUTION:An aeration system comprises a float F which is held at a specified place on the water surface of a closed water area such as pond, lake, marsh, etc., or river, harbor, etc., a frame K which is fixed at the lower end of a supporting rod L hung from the float and the depth of which is made changeable by the supporting rod, self-contained type aerators B which are fixed on the frame, and a high pressure pump p which feeds high pressure water to the aerators through a water supply pipe H2. In the aerator, fluid discharge nozzles are installed which have discharge nozzle holes with a ring cone shape so that sucked air is atomized by high pressure water discharged from the inner and outer periphery of a cylindrical nozzle to be mixed with water and jetted into water together with the high pressure water for aeration. Also, cylindrical nozzles are installed which are located in series at one end of the extended line of longitudinal shaft center of the fluid discharge nozzles.</p> |
