Chlorine Dioxide in Liquefied Carbon Dioxide Spray
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for storing and spraying chlorine dioxide face challenges such as short preservation time, container corrosion, and compliance issues with the High Pressure Gas Safety Act.
Innovation Solution
A spray agent packed in a container containing chlorine dioxide dissolved in liquefied carbon dioxide gas, with a concentration range of 1×10−2 to 1×105 ppm, is developed. This solution involves generating chlorine dioxide, charging it into a pressure-resistant container, and dissolving it in liquefied carbon dioxide gas, which is then used for spraying.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If chlorine dioxide is stored as a 5% aqueous solution, then it is safer and easier to handle, but it cannot be stored for a long period of time and may corrode containers
Solution Approach 1:
The patent changes the physical state parameter of chlorine dioxide from aqueous solution to dissolved gas in liquefied carbon dioxide. This parameter change enables long-term storage (solving the storage period problem) while maintaining safety and ease of handling (solving the ease of operation problem), as the new formulation is stable and does not corrode containers.
2Reliability
If chlorine dioxide is sprayed into a space, then it exerts bactericidal and disinfecting effects, but it may be considered as high-pressure gas production under the High Pressure Gas Safety Act
Solution Approach 1:
The patent introduces liquefied carbon dioxide as an intermediary medium to dissolve and transport chlorine dioxide. When sprayed, the liquefied carbon dioxide vaporizes first, releasing chlorine dioxide gradually. This intermediary approach prevents direct high-pressure gas release, thereby solving the legal compliance risk while maintaining the disinfecting effect.
3Reliability
If high-concentration chlorine dioxide is produced industrially, then it has strong bleaching and disinfecting effects, but it may react to produce high-concentration chlorine and poses explosion risk
Solution Approach 1:
The patent changes the concentration parameter and physical state of chlorine dioxide from high-concentration aqueous solution to low-concentration dissolution in liquefied carbon dioxide. This parameter change reduces the risk of chlorine generation and explosion while maintaining effective disinfecting capability through controlled release.
Solution Approach 2:
The patent uses liquefied carbon dioxide as an inert atmosphere to dissolve and stabilize chlorine dioxide. The inert carbon dioxide environment prevents unwanted chemical reactions between chlorine dioxide and other substances, thereby eliminating the safety risks of chlorine generation and explosion while preserving the disinfecting effect.
