Research on air purification efficiency by nonthermal plasma along with the application of magnetic field

Nonthermal plasma created by high-voltage dc power supply can be used to collect precharged suspended particulates, whereas nonthermal plasma, generated by high-voltage pulsed power supply is used to remove harmful gases in the air, but how to increase the efficiency is not clear. In this paper, it is novel to apply magnetic field to air purification to increase the purification efficiency. Effect of magnetic field is analyzed. It can be concluded that purification efficiency can be improved significantly along with the application of magnetic field.
