Ozone is an effective bactericide with strong oxidizing properties, capable of eliminating a wide range of bacteria, viruses, and microorganisms. It decomposes into oxygen at room temperature, leaving no secondary pollution or residue. Due to its pungent, fishy-rotten-egg odor and strong irritant nature, people naturally avoid it upon sensing discomfort, thereby preventing severe poisoning and ensuring a high level of safety.
Ozone-sterilizing washing machines operate by releasing ozone generated by an onboard unit into the wash water throughout the various stages of the cycle, achieving efficient sterilization, disinfection, and deodorization. To ensure effective sterilization, the ozone concentration in the water must be maintained between 0.1 and 0.5 mg/L. Since ozone is highly soluble in water, significant leakage from the machine is unlikely under controlled generation rates unless excessive ozone is produced. Potential leakage points include the water inlet section, the drum seal during washing, the drainage and exhaust phases, and the piping connections between the ozone generator and the machine; therefore, installing a fixed ozone leak detector within the ozone washing compartment is essential.
Additionally, the washing chamber is typically equipped with an ozone destruction system that neutralizes the ozone, allowing for safe entry into the area after 20 to 30 minutes.
Our company manufactures ozone detection sensor capable of monitoring ranges of 0–10 ppm and 0–5 ppm with resolutions of 0.1 ppm and 0.01 ppm, respectively. These ozone detector features switch outputs (using normally open/normally closed passive relays); when the concentration reaches a preset threshold, the system triggers an audible and visual alarm while simultaneously activating an exhaust fan and shutting down the ozone generator, thereby effectively preventing hazardous situations.
Beyond monitoring for ozone leaks, there are other applications related to gas-phase ozone disinfection, such as:
1. Concentration monitoring: Ozone detectors measure the ozone concentration in the air to ensure it meets the standards required for effective sterilization.
2. Safety protection: High concentrations of ozone irritate the human respiratory tract. Detectors monitor for leaks; if ozone levels exceed safe limits, they signal the main control chip to automatically shut down the generator, thereby preventing health risks.
3. Intelligent regulation: Based on the level of soiling on clothing, the ozone gas detector provides feedback to adjust the ozone generator's operating power, balancing energy efficiency with performance a feature requiring more advanced system configuration.
