Efficient method to remove NOx and SOx by dielectric barrier discharge-photocatalysts hybrid process

摘要

A dielectric barrier discharge - photocatalysts hybrid system is provided to process nitric oxide and sulfur oxide included exhaust gas with a simple system which is necessary for activation of photocatalyst. A dielectric barrier discharge - photocatalyst hybrid system for removing exhaust gas includes the followings: a plasma reactor(10) in which dielectric balls coated with the photocatalyst are filled; an exhaust gas inlet(20) in which exhaust gas is flowed with a mass flow controller(30), and formed on one side of the plasma reactor; a purified gas outlet(22) in which the purified exhaust gas is discharged, and passed through the plasma reactor. The plasma reactor is connected to a power supply(40), a pulse generator(46) and a voltage/frequency measuring device(42).
