Abstract
(EN)
The present invention relates to a plasma torch capable of stably generating plasma with high power (MW class), the plasma torch comprising a torch body (200) that has a cylindrical shape and is composed of a plurality of stacked segments (210) disposed between a rear electrode unit (110) and a front electrode unit (120) and forming a circular channel (201 ) through which gas flows in an axial direction (C), wherein the segment (210) has a circular disc shape in which a circular through hole (211) is formed in the center to form the channel (201) and comprises: a plurality of gas supply ports (212) forming a flow path, the flow path being formed in a spiral shape along the circular through hole (211) on one side of the segment (210) so as to introduce a reactive gas; a cooling flow path (213) which has a flow path formed so as to surround the through hole (211) and through which cooling water flows; a cooling water supply flow path (214) vertically penetrating the segment to form a flow path for supplying the cooling water; a cooling water discharge flow path (215) vertically penetrating the segment to form a flow path for discharging the cooling water; a gas supply flow path (216) vertically penetrating the segment to form a flow path for supplying a discharge gas; a gas branch flow path (217) branched from the gas supply flow path (216) so as to be connected to the gas supply port (212); a cooling water supply branch flow path (218) branched from the cooling water supply flow path (214) so as to be connected to the cooling flow path (213); and a cooling water discharge branch flow path (219) branched from the cooling flow path (213) so as to be connected to the cooling water discharge flow path (215).
