<p>PURPOSE: A diffuser of aeration tank capable of rapid installation and dismantlement is provided, in the diffusing device of entire area diffusing type, the diffusing pipe is simple and easy to install, so that the damaged or breakaway diffuser can be rapidly dismantled and reassembled without emptying the whole water in the aeration tank or operational interruption of the system. CONSTITUTION: In the rectangular aeration tank covered by slave having an opening to give a way for the unit assembly of diffusion pipe (1), the rectangular aeration tank comprises a vertical pipe (4) set at the central position extending to the bottom with a fixed distance to the bottom fixed by a distance regulation bar (4-4), connecting from the top end to an air header pipe (2) for supplying air to the unit assemblies of the diffusion pipe (1), and having two bilaterally symmetrically branched pipes (4-3) at the bottom end; a rotational connection device (3) for connecting rotationally, air tightly the branched pipes (4-3) with the unit assemblies of the diffusion pipe (1); unit assemblies of diffusion pipe (1) set bilaterally symmetrically to the vertical pipe (4) and formed into a grate frame.</p> |
