Abstract
A plasma generation device relates to the field of environmental disinfection. The plasma generation device includes a frame, a discharge needle, and plasma generating barrels. The plasma generating barrels form an array in the frame, without an inter-barrel gap. The discharge needle is provided on a geometric centerline in each of the plasma generating barrels. A distance from a discharge endpoint of the discharge needle to any point on an edge of the plasma generating barrel is identical. In combination with advantages of a circular cylindrical plasma generating barrel and a square cylindrical plasma generating barrel, the plasma generation device maximizes the ventilation rate and the disinfection efficiency of plasma ionization at a most economical voltage.
