Ozone Concentrator Using Venturi Inlet for High-ppm Dissolution
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional sanitizing systems using ozonated water are limited by low ozone concentrations, typically around 2-4 ppm, which restricts the efficiency and speed of sanitization processes.
Innovation Solution
The system employs a venturi inlet downstream of the pump to draw ozone into a pipe, combined with a pressure regulator, static mixer, degas valve, and ozone monitoring system, allowing for recirculation and controlled ozone introduction to achieve higher ozone concentrations in water, up to 10 ppm or higher, facilitating faster and more effective sanitization.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If conventional sanitizing systems use standard ozone dissolution methods, then the system is simple to operate, but the ozone concentration in water is limited to 2-4 ppm
Solution Approach 1:
The system divides the ozone dissolution process into multiple stages: (1) initial ozone injection and dissolution in the contact tank, (2) recirculation through the venturi injector for additional ozone concentration, and (3) controlled release to maintain high ozone levels. This segmentation allows achieving 10+ ppm concentrations by breaking down the complex dissolution process into manageable steps.
Solution Approach 2:
The system performs preliminary ozone dissolution in the contact tank before the water is released for sanitization. The venturi injector is positioned to draw ozone into the recirculating water flow in advance, ensuring high ozone concentration is achieved before the water leaves the system. This preliminary action allows the water to be pre-saturated with ozone at high concentrations.
2Loss of time
If higher ozone concentrations are achieved, then sanitization time is reduced, but the system complexity increases
Solution Approach 1:
The pump continuously recirculates water through the venturi injector and contact tank, maintaining continuous ozone dissolution and concentration. This continuous recirculation ensures that high ozone concentrations are sustained throughout the sanitization process, reducing the time needed to achieve effective sanitization levels compared to batch methods.
Solution Approach 2:
The system uses a controller to monitor and adjust the pump operation and ozone injection, ensuring optimal ozone concentration is maintained. This feedback control allows the system to automatically adjust parameters to achieve target concentrations, reducing the need for manual intervention and complex operator procedures.
3Reliability
If ozone is introduced at higher concentrations, then sanitization effectiveness increases, but controlling ozone dissolution becomes more difficult
Solution Approach 1:
The venturi injector design allows ozone to be drawn into the water flow automatically based on the water pressure and flow rate. The system self-regulates the ozone injection rate according to the recirculation conditions, reducing the need for manual control adjustments. The controller automatically monitors and adjusts parameters to maintain optimal ozone concentration levels.

AI summary
Systems and methods for dissolving ozone gas in a liquid. An embodiment can comprise a tank having an upper region, a lower region, and a discharge outlet, all disposed in a specified geometry. A pump can be coupled with a liquid inlet in order to receive a liquid therefrom and to deliver the liquid via a pipe to the upper region of the tank. The pump can be coupled with the lower region of the tank in order to receive the liquid from the tank and to recirculate the liquid to the upper region of the tank. The apparatus can include an ozone inlet to receive ozone into the tank. The ozone inlet can comprise a venturi inlet disposed on the pipe downstream of the pump. The liquid can be released from the tank and depressurized, thereby providing for the ozone to emerge from the liquid as gas bubbles. The released liquid can be selected for a two-stage gas and aqueous cleaning process.
