Abstract

AbstractThe application of pulsed corona discharge plasma technology in air pollution control is analyzed by experiment on double dielectric barrier discharge reactor (DDBD) and pulsed corona discharge reactor (PCD). The results show that the optimal operating frequency of PCD is 1600 Hz, operating power is 1–4.8 kW. PCD reactor is easier to control electric field intensity in appropriate value because of wider operating power and operating voltage. When it is applied in sewage pumping station with an activated carbon adsorption device at the tail, a better deodorization effect is obtained. In addition, different operating frequencies mainly affect the output power, but do not affect the development trend, and different application sites correspond to different output power, such as deodorization, dioxin purification, fresh air system. Pulsed corona discharge plasma deodorization technology has the advantages of good deodorization effect, controllable ozone escape and flexible operation. With the development of power supply technology, the process cost is gradually reduced, so it has good market application value.KeywordsNon-thermal plasmaOdor controlDielectric barrier dischargePulsed corona discharge
