Sterilization equipment using ozone generators

Abstract

A sterilization device using an ozone generator is suitable for water sterilization. It includes a main body, a power supply, a switch, an air pump, an ozone generator, a programmable logic controller (PLC), and a human-machine interface (HMI). The PLC receives switch signals and, in conjunction with the HMI, sets parameters and monitors status to regulate the start-up and shutdown of the air pump and the ozone generator, as well as their operating time. When the air pump delivers gas to the ozone generator to produce ozone, it is introduced into the venturi tube of the water flow channel through a pipeline, ensuring thorough mixing with the water to achieve sterilization. This invention aims to achieve both thorough mixing and purification with a single device, simplifying the system architecture to save production and maintenance costs, while simultaneously reducing pressure drop losses caused by water flowing through the device, ensuring the overall efficiency of the pipeline system.
