METHOD AND APPARATUS FOR PRODUCING LIQUID FOR STERILIZATION USE

摘要

An apparatus includes a pipe line, water supplying devices, gas supplying devices, a plasma generation device, a cooling device for cooling water flowing in the pipe line, and a vessel. The plasma generation device has a high-voltage electrode and a ground electrode which are provided outside the pipe line to face each other with the pipe line interposed therebetween and applies a plasma treatment continuously to the water flowing in the pipe line by generating dielectric barrier discharge between the high-voltage electrode and the ground electrode. The cooling device cools the water to have a low temperature of 10° C. or lower. The plasma treatment is applied to generate a plasma-treated solution in which superoxide anion radicals (O2−.) or a precursor thereof is diffused in the water and a microbicidal activity is sustained.

1. An apparatus for producing liquid for sterilization use, comprising:
a pipe line; a water supplying device for supplying the pipe line with water; a gas supplying device for supplying the pipe line with nitrogen gas; a plasma generation device having a high-voltage electrode and a ground electrode 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 flowing in the pipe line by generating dielectric barrier discharge between the high-voltage electrode and the ground electrode; a cooling device for cooling the water flowing in the pipe line; and a vessel for holding the water flowing out of the pipe line; wherein the cooling device cools the water to have a low temperature of 10° C. or lower, the plasma treatment is applied to generate a plasma-treated solution in which superoxide anion radicals (O2−.) or a precursor thereof is diffused in the water and a microbicidal activity is sustained, and the plasma-treated solution is held in the vessel as the liquid for sterilization used to apply a sterilization treatment by applying the plasma-treated solution to an object.
