Abstract
Systems, methods, and apparatus are contemplated in which a tube cell that produces a dielectric barrier discharge (DBD) is individually configured to minimize the mixing of unwanted byproducts of the generated plasma with an exhaust air stream. The tube cell generates a DBD within a tube cell, such that oxidants or radicals are generated in an environment substantially separated from the exhaust stream. The generated oxidants are directed to intersect with the exhaust stream to minimize the generation of unwanted byproducts. The tube cells are further shaped and arranged in tube cell arrays to alter the flow dynamics of the exhaust stream and the oxidant or radical streams, including mixing of the streams.
Claims18
A system for treating a first stream, comprising:
- a tube cell, comprising:
- an oxidizing flow path for a second stream to flow through the tube and out a plurality of outlets,
- an inner electrode extended through a length of the tube cell,
- a dielectric layer insulating the inner electrode from the flow path, and
- an outer electrode directing the flow path to the plurality of outlets formed in a shell of the outer electrode, wherein an outer surface of the outer electrode comprises micro-surface features that either accelerate or decelerate the outlet stream flowing around the outer surface of the outer electrode;
- and
- a power generator coupled to the inner electrode and the outer electrode to generate a dielectric barrier discharge in the flow path to oxidize the second stream;
- wherein the first stream flows around the exterior of the tube cell to intersect with outlet stream from the plurality of outlets.
The system of claim 16, wherein power to the downstream electrode is pulsed to alter a flow speed towards the downstream electrode.
A system for treating a first stream, comprising:
- a tube cell, comprising:
- an oxidizing flow path for a second stream to flow through the tube and out a plurality of outlets,
- an inner electrode extending through a length of the tube cell,

- and
- a power generator coupled to the inner electrode and the outer electrode to generate a dielectric barrier discharge in the flow path to oxidize the second stream;
- wherein the first stream flows around the exterior of the tube cell to intersect with outlet stream from the plurality of outlets.
