Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing ozonation systems face challenges in providing ozonated water on demand without the need for a continuously recirculating system, as they require energy, can be corrosive, and experience fluctuations in ozone levels due to the need for a holding tank and recirculation processes.
Innovation Solution
A tank-less ozonation system that uses a liquid inlet and outlet with a gas-liquid mixer and separator to rapidly mix and separate ozone from water, allowing for immediate ozonation and dispensing of ozonated liquid with an oxidation-reduction potential of at least 450 mV, with a fluid residence time of less than 5 minutes, eliminating the need for a holding tank and recirculation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a continuously recirculating system is used to maintain ozonated water, then ozone levels can be maintained, but energy consumption increases and corrosion risks arise
Solution Approach 1:
The system uses periodic batch ozonation instead of continuous recirculation. Ozone is generated in cycles, allowing the water to be ozonated in batches and then stored without continuous energy input. This eliminates the need for constant recirculation while maintaining reliable ozone levels when needed.
Solution Approach 2:
The system performs preliminary ozonation of water in batches before storage. By pre-ozonating the water and storing it in an insulated container, the system prepares the disinfectant in advance without requiring continuous energy consumption or recirculation during storage.
2Duration of action of stationary object
If a holding tank with recirculation is used, then ozonated water can be stored, but the system complexity and device requirements increase
Solution Approach 1:
The invention extracts and eliminates the complex recirculation pump and control system from traditional ozonation systems. By using simple batch generation followed by passive storage in an insulated container, the system achieves extended storage duration without the need for complex active recirculation mechanisms.
Solution Approach 2:
The insulated storage container serves itself by maintaining ozone levels through thermal insulation without requiring active recirculation or additional energy input. The system uses the natural properties of the insulated container to preserve ozonated water for extended periods.
3Reliability
If ozone is continuously generated and recirculated, then disinfection effectiveness is maintained, but harmful corrosive effects increase
Solution Approach 1:
By generating ozone periodically in batches rather than continuously, the system reduces the cumulative corrosive exposure to system components. The insulated storage container preserves the ozonated water without requiring continuous ozone generation, thereby maintaining disinfection effectiveness while minimizing corrosion.
4Loss of time
If a tank-less system with rapid mixing is used, then on-demand ozonation is achieved, but the residence time for complete ozonation is reduced
Solution Approach 1:
The system performs preliminary ozonation by generating ozone in advance and allowing it to dissolve in water during the batch process. This pre-dissolution phase ensures complete ozonation before the water is stored and dispensed on-demand, eliminating the need for lengthy preparation time during actual use.

AI summary
A system is described herein which provides an ozonated liquid. The system comprises a liquid inlet arranged to continuously accept a liquid into the system at a desired flow rate; a liquid outlet to dispense ozonated liquid out of the system, the ozonated liquid having an oxidation-reduction potential of at least 450 mV due solely to ozone dissolved in the liquid, the liquid outlet being in fluid communication with the liquid inlet and arranged to dispense the ozonated liquid out of the system at the desired flow rate. The system has a tank-less ozonation flow path between the liquid inlet and the liquid outlet, the flow path adapted to ozonate the accepted liquid, producing the ozonated liquid to be dispensed out of the system. The accepted liquid has a fluid residence time in the ozonation flow path of less than 5 minutes prior to being dispensed as the ozonated liquid.
