Aerosol Chlorine Dioxide Generator via Segmented Mixing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing chlorine dioxide solution agents are insufficient in generating highly fast-acting chlorine dioxide, and previously proposed methods for generating chlorine dioxide using chlorite salts and activators lose their fast-acting properties over time.
Innovation Solution
An aerosol product with a double-structure container system, where an aqueous solution of a chlorite salt and an acidic substance, such as citric acid, are separated and mixed upon discharge, allowing for immediate and continuous generation of chlorine dioxide, with the chlorite salt and acidic substance being stored in separate containers to maintain stability and fast-acting properties.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If chlorine dioxide is used in the form of aqueous solution for handleability, then ease of operation is improved, but stability deteriorates
Solution Approach 1:
The invention divides the chlorine dioxide generation system into separate components: a chlorite salt composition and an activator composition are stored separately in different containers. The chlorite salt composition (containing NaClO2 and buffering agent) is kept stable until use, while the activator (acidic substance) is stored separately. Upon activation, these components are mixed to generate chlorine dioxide gas, thus maintaining both stability during storage and ease of operation during use.
2Speed
If chlorite salt and activator are mixed before use for fast-acting properties, then speed is improved, but duration of action deteriorates
Solution Approach 1:
The invention prepares the chlorite salt composition and activator composition separately in advance, storing them in stable forms. The chlorite salt is pre-prepared with a buffering agent to maintain stability, while the activator is kept ready but separate. Upon activation, the mixing and chlorine dioxide generation occur immediately, providing fast-acting properties. The system maintains duration of action by continuously generating chlorine dioxide from the stored compositions rather than relying on pre-mixed solutions that degrade over time.
3Duration of action of stationary object
If stabilized chlorine dioxide aqueous solution is used for continuous release, then duration of action is improved, but speed deteriorates
Solution Approach 1:
The invention changes the physical and chemical parameters of the chlorine dioxide delivery system by using a dry powder chlorite salt composition instead of aqueous solution. The chlorite salt composition contains NaClO2 and a buffering agent in a dry state, which remains stable for long periods. When the activator (acidic substance) is added, it rapidly generates chlorine dioxide gas. This parameter change from aqueous to dry state enables both long-term stability for continuous release and rapid generation speed when activated.
