Ozone Reactor Design and Production of Prototype with Dielectric Barrier Discharge (DBD) Method

The escalating global population, a predominant contemporary challenge, has resulted in a proportional rise in the need for sterilization, influenced significantly by various factors such as environmental pollution, epidemic diseases, and heightened consumption demands. Sterilization finds active application in numerous industries, including food, health, and textiles, with the diversity of methods and applications expanding through ongoing research and development efforts. Ozone (O3), distinguished by its potent disinfectant and oxidation capabilities, has witnessed increasing utilization due to its unique attributes, including the ability to dissolve without leaving residues and cost-effective artificial production using air or oxygen sources. Its superiority over other disinfectants positions it as a sterilizer with a foreseeable surge in usage, evident through ongoing studies. This thesis focuses on the artificial production of ozone, specifically utilizing the dielectric barrier discharge (DBD) method, which operates on the principle of creating a plasma arc, considering factors such as cost-effectiveness, long lifespan, and efficiency. The design, material selection, and prototype manufacturing of the ozone reactor are detailed, presenting an independent design with unique dimensions compared to devices produced to date. The literature review, based on parameters from existing devices and patents, guides material selection for the DBD ozone reactor, emphasizing factors such as maximum efficiency, long lifespan, cost-effectiveness, market availability, and processability. Upon completion of the ozone reactor's manufacturing, an impartial organization conducted tests to assess its environmental sterilization effectiveness. The application of ozone produced by the reactor demonstrated a surface sterilization efficiency of 89.90% for Enterovirus and 93% for Clostridium, and a liquid sterilization efficiency of 89.90% for Enterovirus and 61.3% for Clostridium. These test results underscore the robust sterilization effect and high efficiency of ozone produced by the DBD ozone reactor, which requires only air or oxygen as a source for production.
