摘要
Ozone emission of corona discharge has been studied for many years. We use Differential Optical Absorption Spectroscopy (DOAS) to build an optical detection system with a limit of 465 ppm and precision of 0.01 ppm to detect the ozone concentration, on this basis, we investigated the effect of voltage, materials, number of electrodes and gas flow on ozone emission. Compared with the negative corona discharge, positive corona produces a small amount of ozone at the same voltage, and more ozone is produced in positive pulse than that in positive DC. The electrode materials do not change the current-voltage characteristics of corona discharge, but silver and copper significantly reduce ozone production. The number of electrodes affects the electric field distribution thus the electron density is changed. At the same current, the more electrodes, the less ozone is generated. With the increase of gas flow, the ozone concentration decreases and reaches saturation concentration within a shorter time.
