<p><P>PROBLEM TO BE SOLVED: To provide an air diffusion nozzle capable of efficiently diffusing an air diffusing gas by installing a small-sized air diffusion pipe provided with the air diffusion nozzle in a tank, and an air diffusion tank. <P>SOLUTION: The air diffusion nozzle 10 connected to the air diffusion pipe A in a detachable manner has a pipe 12 opened at its leading end to allow the air diffusing gas to flow and a porous hollow cylindrical body 14, and the pipe 12 opened at its leading end is loosely mounted in the porous hollow cylindrical body 14. By this constitution, a gap C is formed between the pipe 12 and the porous hollow cylindrical body 14. The air diffusing gas flowing through the pipe 12 from the air diffusion pipe A flows in the internal space part of the porous hollow cylindrical body 14 from the leading end of the pipe 12 and passes through the gap C between the pipe 12 and the porous hollow cylindrical body 14 to be uniformly diffused over the whole surface of the porous hollow cylindrical body 14. <P>COPYRIGHT: (C)2008,JPO&INPIT</p> |
