Cold plasma generation device for controlling atmospheric gas pollution, has central electrode and helical shaped external electrode, where device generates cold plasma by forming electric discharges between coaxial electrodes

摘要

The device has a central electrode (1) and an external electrode (2) with a helical shape. The device generates cold plasma by forming electric discharges between coaxial electrodes. The electric discharges are of corona effect discharge type, potential barrier discharge type, and radio-frequency or micro-wave discharge types.
