<p>PURPOSE:To oxidize efficiently sewage contg. org. sludge by radiating air jet toward the deep direction of the liquid by the liquid jet having high directivity and inducing the downward liquid flow over a wide range enclosing the liquid jet thereof. CONSTITUTION:A revolving shaft 4 in common use as an air feed pipe 3 is used as a driving shaft for an electric motor 5. An air jet-water flow device 10 is disposed to rhe lowermost end of the shaft 4 and a water flow device 11 is fixedly disposed above said device. Both devices are so arranged that the devices can be rotated and operated simultaneously. The device 10 is constituted together with a concentrical shell 12 forming a flow passage communicating with above and blow in a way that air can be fed. Said device is constituted of an air ejecting port 7 having many through-holes and a vane 13 installed radially between said port and the shaft 4 disposed with said port at the front end thereof. The port 7 may be constituted of a single foamed material having open cells formed to an annular or plug shape or may be constituted of a perforated plate.</p> |
