REACTIVE BED PLASMA AIR PURIFICATION

摘要

A plasma air purification device for producing a breathable effluent from contaminated air is disclosed which overcomes the limitations of known air purification devices. The present invention comprises an alternating current plasma device with a porous spherical or granular material packed into the plasma zone. The device of this invention provides air purification by decomposiing and deactivating toxic contaminants. The contaminants that can be successfully processed include toxic vapors, gases and aerosols. In addition, the air by-products such as NOx, O3 and CO are controlled to below toxic levels. The presence of the porous packing enhances the performance of the device by further reducing air by-products formation, maximizing processing efficiency reducing power consumption, and increasing volume flow rate (i.e. reducing carrier gas residence time).
