Parallel Adsorption Cylinders for Ozone Concentration
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for concentrating ozone gas face challenges in maintaining stable concentration and preventing rapid pressure increases during desorption, leading to self-decomposition and inefficient ozone extraction.
Innovation Solution
The method involves using at least two adsorbing cylinders in parallel, where ozone-oxygen mixture gas is adsorbed and desorbed alternately, with pressure equalization between the cylinders to manage internal pressures and prevent rapid increases, allowing for higher adsorption pressures and increased ozone concentration without damaging equipment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If adsorption pressure is increased to increase the adsorbed amount of ozone gas, then ozone concentration is improved, but pressure increases rapidly in the concentrated ozone extraction pipe causing self-decomposition
Solution Approach 1:
The system divides the adsorption process into multiple stages using sequential adsorption beds. The first adsorption bed operates at high pressure to maximize ozone uptake, while the second adsorption bed receives the desorbed ozone at lower pressure. This segmentation allows the system to achieve high ozone concentration without causing rapid pressure increases in the extraction pipe, as the pressure surge is distributed across multiple beds rather than concentrated in one.
2Quantity of substance
If adsorption pressure is increased to concentrate ozone gas, then ozone concentration ratio is improved, but rapid pressure increase in the pipe leads to equipment damage risk
Solution Approach 1:
The system performs preliminary pressure equalization between the first and second adsorption beds before initiating the desorption process. By equalizing pressures in advance, the system prevents sudden pressure surges during desorption that could damage equipment. The pressure equalization step ensures that when ozone is desorbed from the first bed, the pressure increase is gradual and controlled, protecting the extraction pipe and vacuum pump from mechanical stress.
3Productivity
If a decompression section is added to the system, then ozone extraction efficiency is improved, but device complexity increases
Solution Approach 1:
The system merges the decompression function with the existing adsorption bed structure by using the second adsorption bed as both an adsorption unit and a pressure equalization chamber. Instead of adding a separate decompression section, the system utilizes the dual-purpose design where the second bed receives desorbed ozone, equalizes pressure with the first bed, and facilitates controlled decompression. This integration achieves efficient ozone extraction while minimizing additional equipment and structural complexity.

Function Achieved in This Case
This approach effectively increases the concentration ratio of ozone gas, prevents self-decomposition, and allows for safer operation by controlling pressure equalization to reduce the risk of equipment damage, resulting in a more efficient ozone gas extraction process.
Implementation Method 1
ozone-oxygen mixture gas is caused to act on the adsorbent in a non-cooled state that is contained in each adsorbing cylinder, so that ozone gas is selectively adsorbed to the adsorbents
Implementation Method 2
a depressurizing process is subjected to each adsorbing cylinder during an ozone gas desorption operation, so that the ozone gas is desorbed from the adsorbents

AI summary
A method of concentrating ozone gas including: causing ozone gas contained in ozone-oxygen mixture gas to be selectively adsorbed to adsorbents which are filled in a non-cooled state in at least two adsorbing cylinders arranged parallel to one another; desorbing the ozone gas from the adsorbents by subjecting a depressurizing process to each adsorbing cylinder during an ozone gas desorption operation; repeating an adsorption step and a desorption step alternately in the at least two adsorbing cylinders; and controlling the adsorbing cylinders, in such a way that one of the adsorbing cylinders is performing the adsorption step while another one of the adsorbing cylinders is performing the desorption step.
