Ozone Generation Device Cooling Space Segmentation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In ozone generation devices, the temperature difference across electrode tubes due to silent discharge leads to reduced ozone generation efficiency, as the ozone gas outlet side becomes hotter than the raw material gas inlet side, causing cooling water flow inefficiencies and ozone decomposition.
Innovation Solution
The ozone generation device configuration includes a cylindrical tank with parallel electrode tubes, discharge tubes forming gaps, and a cooling space with a cooling medium inlet and outlet arranged diagonally, where discharge tubes are not placed inside electrode tubes in the highest temperature area to prevent overheating and maintain efficient cooling.

1Area of stationary object
If cooling water inlet and outlet are arranged on diagonal sections to maximize cooling coverage, then cooling space utilization is improved, but cooling water flow speed becomes uneven causing stagnation and reduced cooling efficiency
Solution Approach 1:
The cooling space is divided into multiple inlet and outlet openings distributed along the electrode tubes rather than using single diagonal inlet/outlet. This segmentation allows cooling water to flow uniformly through different sections, preventing stagnation while maintaining comprehensive cooling coverage.
Solution Approach 2:
Different sections of the cooling space are provided with cooling water inlet and outlet openings at different locations. The cooling water flow path is locally optimized in each section to ensure adequate flow speed and prevent stagnation while maintaining overall cooling efficiency.
2Productivity
If cooling water flow speed is increased to prevent stagnation, then cooling efficiency is improved, but energy consumption and system complexity increase
Solution Approach 1:
Multiple cooling water inlet and outlet openings are distributed along the electrode tubes, creating multiple flow paths. This segmentation allows cooling water to flow through different sections without requiring high flow speeds in any single path, reducing energy consumption while maintaining cooling efficiency.
Solution Approach 2:
The cooling water flow is distributed across multiple spatial dimensions by providing inlet and outlet openings at different locations along the electrode tubes. This multi-dimensional distribution eliminates the need for high flow speeds in a single direction, reducing system complexity while maintaining cooling efficiency.
3Productivity
If discharge tubes are arranged inside electrode tubes to maximize ozone generation, then ozone generation efficiency is improved, but temperature increase causes ozone decomposition
Solution Approach 1:
The cooling system is locally optimized by providing cooling water inlet and outlet openings at specific locations along the electrode tubes. This local cooling approach prevents temperature increase in the discharge gap region where ozone is generated, while allowing other sections to operate at higher temperatures without affecting ozone stability.
Solution Approach 2:
The electrode tubes are segmented into different cooling zones with independent cooling water inlet and outlet openings. This segmentation allows the discharge gap region to be specifically cooled to prevent ozone decomposition, while other sections can operate independently.

Implementation Method 1
a cooling medium inlet (21) formed in a lower section on one end side of the cooling space (19); a cooling medium outlet (22) formed in an upper section on the other end side of the cooling space (19)
Implementation Method 2

AI summary
A cylindrical tank-shaped container including: plural parallel electrode tubes; discharge tubes arranged inside the electrode tubes, each forming a discharge gap; a pair of end plates that penetrate and hold both of end sections of the plural electrode tubes; a cooling space formed by the pair of end plates and the inner surface of the tank-shaped container divided between end plates; a cooling medium inlet and a cooling medium outlet formed in opposite end sides of the cooling space; a raw material gas inlet that introduces raw material gas to be sent to the discharge gaps; and an outlet for ozone gas generated from the raw material gas by silent discharge in the discharge gaps, providing an electrode tube in which a discharge tube is not arranged, among the plural electrode tubes, that have surrounding coolant medium that reaches at least a prescribed temperature resulting from the silent discharge.
