Rotary degasser and rotor therefor
ActiveUS8535603B2Efficiently circulatedWell mixedMelt-holding vesselsStirring devicesImpellerDegasser
A device for dispersing gas into molten metal includes an impeller, a drive shaft having a gas-transfer passage therein, and a first end and a second end, and a drive source. The second end of the drive shaft is connected to the impeller and the first end is connected to the drive source. The impeller includes a first portion and a second portion with a plurality of cavities. The first portion covers the second portion to help prevent gas from escaping to the surface without entering the cavities and being mixed with molten metal as the impeller rotates. When gas is transferred through the gas-transfer passage, it exits through the gas-release opening(s) in the bottom of the impeller. At least some of the gas enters the cavities where it is mixed with the molten metal being displaced by the impeller. Also disclosed are impellers that can be used to practice the invention.

Disclosed is a system and method for treating domestic and industrial biological waste using diffusers to force circulation and aerate a treatment lagoon. Several lagoons may be used in series to treat raw waste and different variations may be employed to stepwise process the waste. A blend of aerobic and anaerobic microbes is chosen to remove undesired species initially present in the waste or later formed therein, as well as to process the waste itself, depending on the nature of the waste. Aeration with slightly ozonated or oxygenated air facilitates rapid and complete processing of large amounts of waste.
