Abstract
This disclosure relates to aggregating, neutralizing, and filtering ultra-fine particles in fluids such as air and water. Fluid may be drawn from an ambient environment into a neutralization chamber. Within the neutralization chamber, particles in the fluid may be agglomerated. An acoustic field may be applied to the fluid to agglomerate the particles. The agglomerated particles may be exposed to light. The light may denature or deactivate the agglomerated particles. The agglomerated and inert particles maybe passed through a filter. After agglomeration and neutralization, the fluid may be released back into the ambient environment.
Claims9
A system for filtering air flowing through a duct, the system comprising:
- electronic circuitry that generates an acoustic field that agglomerates multiple first particles in the air flowing through the duct that are each smaller than a threshold size into one or more second particles each larger than the threshold size;
- a temperature sensor;
- and
- a filter sufficiently dense to catch the one or more second particles;
- wherein:
- the electronic circuitry is configured to control the acoustic field based on a temperature measured by the temperature sensors;
- the electronic circuitry comprises a light generator that generates heat;
- and
- the temperature sensor monitors a temperature of the light generator.
