Electrolytic bath, device and method for preparing EOW without metal ions

Abstract

The invention relates to the technical field of EOW preparation, in particular to an electrolytic bath, a device and a preparation method for preparing EOW without metal ions. The device for preparing the EOW free of the metal ions comprises theelectrolytic bath, the electrolytic bath comprises a bath body, an anionic membrane assembly, a cathode and an anode, a cavity is formed in the bath body, a liquid injection opening used for injecting electrolyte, a water inlet used for feeding pure water and a water outlet used for discharging the EOW are further formed in the bath body, and the anionic membrane assembly is located in the cavity. The cavity is divided into a cathode cavity and an anode cavity, the liquid injection opening is communicated with the cathode cavity, the water inlet and the water outlet are both communicated with the anode cavity, the cathode is located in the cathode cavity, and the anode is located in the anode cavity. According to the present invention, the anion membrane assembly only allows the passing of the negatively charged ions and restricts the passing of the positively charged ions, such that the metal cations in the cathode cavity cannot enter the anode cavity through the anion membrane assembly, the EOW generated in the anode cavity does not contain the metal cations, and the good sterilization effect of the prepared EOW is ensured.

Description

technical field [0001] The invention relates to the technical field of EOW preparation, in particular to an electrolytic cell, a device and a preparation method for preparing EOW without metal ions. Background technique [0002] The earliest application of electrolyzed-oxidizing water (EOW) can be traced back to Japan in the 1980s. Because of its remarkable bactericidal effect on MRSA, it was first used in the field of medicine, followed by medical equipment. Clean and disinfect. After years of research and practice, the advantages of EOW sterilization, such as high sterilization efficiency, no residual toxicity after sterilization, harmlessness to the human body, no pollution to the environment, and environmental protection, have been gradually accepted by people and gradually promoted in many fields. [0003] Due to the unique functions of EOW, the preparation of EOW is a hotspot of active research. However, the EOW prepared by using the existing EOW device and the exist...
