Although charged fog has been widely applied to industrial sources of fugitive dust, little quantitative data are available on fogger control effectiveness on particu- late matter. To obtain such data, a full- scale demonstration of a charged fogger was conducted on several appropriate industrial fugitive emission sources.

Jun 01, 2018  Fog collection can be a sustainable solution to water scarcity in many regions around the world. Most proposed collectors are meshes that rely on inertial collision for droplet capture and are inherently limited by aerodynamics. We propose a new approach in which we introduce electrical forces that can overcome aerodynamic drag forces. Using an ion emitter, we introduce a space charge into

Electrostatically charged liquid such as water is supplied via rotating structure to impinge on a baffle. The latter deflects the charged liquid onto a rotating insulative, frusto-conical surface on which the charged liquid forms a film which flows forwardly to an annular edge. Gas such as air, sweeping past the edge, impacts the layer arriving at the edge and produces fine charged droplets of ...

Electrostatically charged droplets provide less dripping and pooling of liquid compared to standard fogging, which is better for reaching difficult access areas due to dispersion. Positive charged droplets are attracted to charged or neutral target surfaces, which ensures uniform coverage with the droplets in the mist/fog.

Aug 13, 2020  Electrostatic Sprayers kill on contact. Flammable solutions should never be used in electrostatic sprayers. Nano Atomizers produce a dry fog that is not charged with electricity. This dry fog application is safe for fabrics and electronics. Thermal foggers (above) generally produce smaller droplets, with a minimum diameter of 1 micrometer.

Dry Fog Dust Control Wind Breaks Dust Fly Ash

The interaction between charged fog droplets and dust particles varied across particulate types but it was noted that the use of fog lowered dust density across all tested materials. For example, when testing dust density of fly ash in a controlled environment, it was found that the fog reduced the density of respirable material by fog by over 91%.
