Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing nascent oxygen generation devices have restrictive performance in deodorization and sterilization of gases due to the instability of active oxygen, which is quickly converted into stable oxygen and water within airflow turbulence, reducing contact opportunities with odor substances and sterilization targets.
Innovation Solution
A gas treatment device comprising an active oxygen supply device with a plasma actuator and an ozone decomposition device, where the plasma actuator generates a dielectric barrier discharge to produce ozone, which is then decomposed into active oxygen, and the induced flow containing active oxygen is supplied to a gas flow path to effectively treat gases.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If air is introduced into the device from the outside to come into contact with active oxygen for deodorization and sterilization, then the device can treat gases, but the active oxygen is quickly converted into stable oxygen and water within airflow turbulence, reducing treatment effectiveness
Solution Approach 1:
The plasma actuator generates ozone and the ultraviolet lamp converts it to active oxygen before the gas treatment process begins. This preliminary generation of active oxygen ensures that sufficient reactive species are available in the gas flow path before turbulence causes decomposition, thereby maintaining treatment effectiveness while enabling gas treatment capability.
2Quantity of substance
If the plasma actuator generates dielectric barrier discharge to produce ozone, then active oxygen can be generated through decomposition, but the active oxygen stability is reduced due to airflow turbulence causing quick conversion to stable oxygen and water
Solution Approach 1:
Ozone serves as an intermediary substance that is stable enough to be generated and transported through the gas flow, then converted to active oxygen by the ultraviolet lamp at the appropriate location. This intermediary approach allows the system to overcome the instability of direct active oxygen generation while maintaining sufficient reactive oxygen for effective gas treatment.
3Productivity
If the induced flow containing active oxygen is supplied to the gas flow path, then deodorization and sterilization can be achieved, but contact opportunities between active oxygen and odor substances are reduced due to quick conversion
Solution Approach 1:
The system preliminarily generates sufficient active oxygen in the gas flow path before the gas encounters turbulence and before contact with odor substances occurs. This ensures that active oxygen is available in adequate quantities and for sufficient duration to effectively deodorize and sterilize the gas, overcoming the limitation of reduced contact time.

Function Achieved in This Case
The device enhances the effectiveness of gas treatment by maintaining active oxygen in a stable state for a longer period, allowing for reliable deodorization and sterilization of gases by ensuring active oxygen contacts and treats the gas effectively before conversion.
Implementation Method 1
when a voltage is applied between the first electrode and the second electrode, the plasma actuator generates a dielectric barrier discharge oriented from the first electrode toward the second electrode
