Abstract
In this paper, a new type of indoor air purification device was designed. Corona discharge combined with catalysis and physical adsorption was used in this device. Formaldehyde (PA), a typical indoor air pollutant, was chosen as the model pollutant. The effects of MnO2 in degradation of PA by electrical discharge were discussed. The results showed that corona discharge can effectively remove PA, and the addition of MnO2 can not only accelerate the degradation rate, but also solve the problem of excessive ozone (O3). Besides, the corona discharge plasma also has the function of in-situ cleaning for MnO2. The new reactor has the characteristics of high efficiency, energy-saving, without secondary pollution.
