Spray deposition, electric-force

Incorporation of electric force fields into pesticide spray application has been shown to greatly Increase the mass-transfer efficiency of the basic droplet deposition process (1-3). The most elementary statement of the conditions necessary for such electric-force augmentation is... 

The efficiency of the trapping of dust by an electric filter may be increased by artificially humidifying the gas to be cleaned or introducing a mist or spray of sulfuric acid at ordinary temperatures [162, 366]. It is noteworthy that the deposition of gold-bearing dust in electric filters increases as the content of sulfuric acid vapor rises from 4 to 12% [372]. In this case the adhesion of the dust to the settling electrode increases as a result of capillary forces (see 13). One must remember, of course, that this makes subsequent purification more difficult. The presence of SO3 in the nickel dust is also clearly the main reason for the poor cleaning of the electrodes [373].
