Abstract
A diffuser module and system for diffusing gas into liquid such as in aeration/mixing of wastewater. Each module has a header pipe and diffusers which receive gas from the header pipe. Each header pipe is equipped with a truss for enhanced structural strength and resistance to bending. The truss may take the form of a buoyancy/ballast pipe connected with the header pipe by purlins.
Claims
1. A diffuser module for applying gas to liquid, comprising: a diffuser assembly including a header pipe and a plurality of diffusers connected with said header pipe to receive gas therefrom; a gas supply line extending to said header pipe to supply gas thereto; a beam member; and a plurality of rigid purlins interconnecting said header pipe and beam.
2. A diffuser module as set forth in claim 1, wherein said beam member comprises a pipe providing a buoyancy chamber and including a buoyancy line connected with said buoyancy chamber for selectively supplying gas thereto for effecting a buoyant condition of said diffuser assembly.
3. A diffuser module as set forth in claim 2, wherein said pipe has opposite ends, and including a cap on one of said ends and a flow control opening on the other of said ends through which liquid enters and is discharged from said buoyancy chamber.
4. A diffuser module as set forth in claim 3, wherein said flow control opening is at an elevation lower than said buoyancy chamber.
5. A diffuser module as set forth in claim 1, wherein said beam member comprises a pipe having open opposite ends to allow liquid to fill said pipe when, submerged.
6. A diffuser as set forth in claim 1, wherein said beam member is located above and is oriented substantially parallel to said header pipe.
7. A diffuser module as set forth in claim 1, wherein said beam member is substantially parallel to said header pipe.
S. A diffuser module for applying gas to liquid, comprising: a diffuser assembly including a header pipe and a plurality of elongated dϊffusers connected to receive gas therefrom; a gas supply line for supplying gas to said header pipe; and a truss connected with said header pipe for structural enhancement, said truss including a beam spaced from and substantially parallel to said header pipe and a plurality of purlins interconnecting said beam and said header pipe.
9. A diffuser module as set forth in claim 8, wherein said beam comprises a pipe providing a buoyancy chamber and including a buoyancy line for applying gas to and exhausting gas from said buoyancy chamber.
10. A diffuser module as set forth in claim 9, wherein said pipe has opposite ends, and including a cap on one of said ends and a flow control opening on the other of said ends through which liquid enters and is discharged from said buoyancy chamber.
11 A diffuser module as set forth in claim 10, wherein said flow control opening is at an elevation lower than said buoyancy chamber.
12. A diffuser module as set forth in claim 8, wherein said beam comprises a pipe having open opposite ends to allow liquid to fill said pipe when submerged.
13. Apparatus for applying gas to a liquid, comprising: a plurality of diffuser modules for immersion in the liquid, each module including a header pipe and a trass connected with said header pipe for structural enhancement thereof, said truss including a beam spaced from and substantially parallel to said header pipe and a plurality of purlins interconnecting said beam and said header pipe; a plurality of diffuser pipes extending from each of said header pipes to receive gas therefrom for discharge into the liquid; and a gas supply line extending to each header pipe to supply gas thereto.
14. Apparatus as set forth in claim 13, wherein said beam comprises a pipe providing a buoyancy chamber and including a buoyancy line for applying gas to and exhausting gas from said buoyancy chamber.
15. A diffuser module as set forth, in claim 14, wherein said pipe has opposite ends, and including a cap on one of said ends and a flow control opening on the other of said ends through which liquid enters and is discharged from said buoyancy chamber.
16. A diffuser module as set forth in claim 15, wherein said flow control opening is at an elevation lower than said buoyancy chamber.
17. A diffuser module as set forth in claim 13, wherein said beam comprises a pipe having open opposite ends to allow liquid to fill said pipe when submerged.
