Enhanced toxic cloud knockdown spray system for decontamination applications
| DWPI Title: Method for decontaminating cloud of e.g. aerosolized chemical or biological warfare agent simulant for military operation in shipping port, involves combining and chemically reacting negatively-charged droplets with toxic material |
| Abstract: Methods and systems for knockdown and neutralization of toxic clouds of aerosolized chemical or biological warfare (CBW) agents and toxic industrial chemicals using a non-toxic, non-corrosive aqueous decontamination formulation. |
| Use: Method for decontaminating a cloud of aerosolized material e.g. aerosolized chemical or biological warfare (CBW) agent simulant and toxic industrial chemical, using non-toxic, non-corrosive aqueous decontamination formulation during de-militarization of chemical weapons, explosives, terrorist attack and industrial accident for military operation in outdoor areas e.g. train derailment, factory and shipping port, open public venue i.e. outdoor sports stadium, and indoor such as underground railway tunnel and shopping mall. |
| Advantage: The method enables evaluating formulations with demonstrated solubility and chemical agent simulant decon efficacy for surface tension so as to reduce surface tension as tactic for enhancing aerosol capture efficiency. The method enables presenting optimum knockdown approaches for specific applications for undergroung railway protection and chemical demilitarization based on feasibility and efficiency of achieving cloud knockdown and decontamination. |
| Novelty: The method involves spraying negatively-charged droplets (12) of aqueous decontamination formulation into a toxic cloud (8). The negatively-charged droplets are combined and chemically reacted with toxic material (9) to neutralize and render the toxic material harmless, where droplet size distribution of the negatively charged droplets is chosen to provide optimum neutralization of the toxic material and another droplet size distribution of the negatively charged droplets is chosen to hasten fallout of droplets of the negatively charged droplets. |
