Solution Overview
Problem
Conventional commercial air purification systems are ineffective in treating incoming air in agricultural structures due to high air exchange rates, making it difficult to reduce or eliminate pathogens such as the Avian Influenza virus.
Innovation Solution
An air purification system comprising anti-viral units with a substrate material supporting a mineral powder containing calcined and partially hydrated dolomite, which generates hydroxyl radicals to inactivate viruses, and optionally incorporating activated charcoal, titanium dioxide, and UV light sources to enhance hydroxyl generation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional commercial air purification systems are used, then air can be treated for viruses and pathogens, but the high air exchange rates in agricultural structures make it difficult to treat incoming air effectively
Solution Approach 1:
The invention changes the chemical parameters of the air by introducing calcined and partially hydrated dolomite that generates hydroxyl radicals. This chemical transformation allows the system to effectively treat pathogens even at high air exchange rates, as the hydroxyl radicals continuously neutralize viruses and bacteria in the incoming air stream without requiring the air to be recirculated multiple times per hour as conventional systems do
Solution Approach 2:
The invention replaces the mechanical filtration and recirculation systems of conventional air purifiers with a chemical-based approach using hydroxyl radical generation. Instead of mechanically filtering air through HEPA filters or recirculating it through UV chambers, the system uses calcined dolomite to chemically neutralize pathogens in the air stream, making it effective for high air exchange rate environments where mechanical systems fail
2Reliability
If calcined and partially hydrated dolomite is used to generate hydroxyl radicals, then viruses can be inactivated by binding to HA protein and envelope, but the system requires specific mineral processing and activation
Solution Approach 1:
The invention applies preliminary action by pre-processing the dolomite mineral through calcination and partial hydration before deployment. This activation process is performed in advance during manufacturing, creating a ready-to-use anti-viral material that generates hydroxyl radicals upon contact with air moisture. The complex processing is done once during production, not during operation, simplifying the ease of manufacture for the final product
3Reliability
If hydroxyl radicals are generated to neutralize pathogens, then viral and bacterial loads are reduced, but the system requires continuous generation of hydroxyls in the air stream
Solution Approach 1:
The invention ensures continuity of useful action by designing the calcined and partially hydrated dolomite to continuously generate hydroxyl radicals as long as it is exposed to air moisture. The material does not deplete quickly but maintains its hydroxyl-generating capability over extended periods, providing continuous pathogen neutralization without requiring frequent replacement or reactivation, thus maintaining reliable pathogen reduction in the air stream
