Abstract
A in-situ forced oxidation system is retrofitted into a wet FGD (flue gas desufurization) scrubber with no vessel penetrations below the water line of the scrubber and no additional load on the scrubber walls.
Claims10
An in situ forced oxidation system for a wet flue gas desulfurization scrubber having a scrubber zone located above a recirculating tank, comprising:
- a series of sparge pipes located in the recirculating tank for bubbling air into the recirculating tank;
- a header assembly connected to said series of sparge pipes for supplying air thereto;
- air supply means for connecting pressurized air to said header assembly without penetrating any scrubber walls below the normal liquid level in the recirculating tank of the scrubber;
- and
- a support leg connected to said series of sparge pipes for supporting said series of sparge pipes on the bottom of the recirculation tank without penetrating any walls of the recirculation tank, said support leg connected to a sparge pipe to extend down along the wall of the recirculating tank to the bottom thereof to support the sparge pipe thereon, said support leg having a hollow portion filled with material preventing buoyancy of the sparge pipe.

A support for sparge pipes of an in situ force oxidation system;
- comprising:
- a wet scrubber having a recirculation tank with sparge pipes located therein for bubbling air through the recirculation tank;
- and
- a support leg for supporting the sparge pipes on the bottom of the recirculation tank of said wet scrubber without penetrating any of the walls of the recirculation tank, said support leg being connected to the sparge pipe to extend down along the wall of the recirculating tank to the bottom thereof to support the sparge pipe thereon, said support leg having a hollow portion filled with material preventing buoyancy of the sparge pipe.
