Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional ozone dissolution chambers are inefficient due to their tall design, which leads to diluted ozone concentration and inadequate contact time between ozone and water, requiring significant space and energy, and existing solutions either require extensive space or suffer from pressure drops and suboptimal contact mechanisms.
Innovation Solution
A compact ozone dissolution chamber utilizing laminar stratification of gas in a turbulent environment, where ozone-containing water is injected horizontally and tangentially at the top, creating a swirling motion that breaks down larger bubbles, resulting in a laminar stratification with finer bubbles and complete dissolution of ozone at the bottom, optimizing ozone-water contact.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Duration of action of moving object
If conventional tall column dissolution chambers are used, then ozone-water contact time is extended, but the chamber height increases and ozone concentration is diluted
Solution Approach 1:
The invention transitions from vertical ozone injection (conventional) to horizontal tangential injection, creating a swirling flow pattern that utilizes rotational motion to enhance mixing and contact time without increasing chamber height. This dimensional change in flow direction enables compact design while maintaining effective contact time
Solution Approach 2:
The invention employs hydraulic principles by using the kinetic energy of horizontally injected ozone-containing water to create turbulent swirling motion. The water flow itself generates the mixing action through tangential injection, eliminating the need for additional mechanical mixers or tall column structures
2Productivity
If ozone is injected at the base of a tall column, then counter-current flow mechanism is achieved, but the chamber becomes tall and space-consuming
Solution Approach 1:
The invention creates dynamic turbulent swirling flow through horizontal tangential injection, where the water continuously circulates and mixes with ozone bubbles in a rotational pattern. This dynamic flow regime enhances mass transfer and oxidation efficiency within a compact chamber volume
Solution Approach 2:
The invention changes the flow parameters by injecting ozone-containing water horizontally rather than vertically, creating a swirling flow pattern with different velocity distributions and residence time characteristics that achieve effective mixing in a smaller volume
3Ease of operation
If spiral tubular treatment coil is used for ozone mixing, then thorough mixing is achieved, but significant pressure drop occurs between inlet and outlet
Solution Approach 1:
The invention replaces the continuous spiral tubular coil with a segmented chamber design where horizontal tangential injection creates discrete swirling flow zones. This segmentation eliminates the long continuous path of the spiral coil, reducing pressure drop while maintaining mixing effectiveness through turbulent eddies
Solution Approach 2:
The invention uses hydraulic principles to create turbulent mixing through the kinetic energy of the injected water stream itself, rather than forcing water through a narrow spiral coil. The tangential injection creates a free-swirling flow that mixes ozone and water efficiently with minimal pressure loss

Implementation Method 1
A compact ozone dissolution chamber utilizing laminar stratification of gas in a turbulent environment, where ozone-containing water is injected horizontally and tangentially at the top, creating a swirling motion that breaks down larger bubbles
Implementation Method 2
The ozone-oxygen bubbles float to the surface slowly, their upward movement slowed by the downward counter flow of the water stream
Implementation Method 3
ensures a high degree of dissolution of ozone in water and, consequently, a high degree of oxidation of organic and metal impurities to a final oxidation state
Implementation Method 4
Ozone has been used as a chemical treatment to oxidize organic matter, metals, bacteria, and viruses in the water being treated. An ozone molecule is a rapid oxidizer that will oxidize organic matter quickly

AI summary
An ozone dissolution chamber utilizes the principle of laminar stratification of gas in a turbulent dissolution chamber. The dissolution chamber is much shorter in height than the conventional tower dissolution chamber, and ensures a high degree of dissolution of ozone in water and, consequently, a high degree of oxidation of organic and metal impurities to a final oxidation state.
