METHOD AND DEVICE FOR PRODUCING BACTERICIDAL LIQUID

摘要

An apparatus and method are provided for continuously generating a plasma-treated solution using plasma efficiently. An apparatus includes: a pipe line 11; water supplying devices 21 and 22 for supplying the pipe line with water; gas supplying devices 31 and 32 for supplying the pipe line with nitrogen gas; a plasma generation device having a high-voltage electrode 12a and a ground electrode 12b which are provided outside the pipe line to face each other with the pipe line interposed therebetween and applying a plasma treatment continuously to the water ML flowing in the pipe line by generating dielectric barrier discharge between the high-voltage electrode and the ground electrode; a cooling device RS for cooling the water flowing in the pipe line; and a vessel 24 for holding the water ML flowing out of the pipe line as treated solution MLp which is liquid for sterilization use.
