TLDR
In this paper, the authors introduced the discharge characteristics and some examples of the applications of the direct current corona with spraying discharge electrodes, and showed that the spray ejected from the discharge electrodes can overcome some difficulties of electrostatic precipitation, such as the back ionization of dusts with high resistivity, the reentrainment of fine dusts and the fouling of discharge electrodes.About:

Wet electrostatic scrubbers for the abatement of submicronic particulate
TL;DR: In this paper, a mathematical model to evaluate the particle removal efficiency in wet electrostatic scrubbers is presented, which is used to find out optimal working condition of WES units, through the maximization of the particle collection efficiency in function of different process parameters: contact time, specific water consumption, water/gas relative velocity, size and charge of sprayed droplets.

Novel wet electrostatic precipitator for collection of fine aerosol
TL;DR: In this article, a novel wet electrostatic precipitator (WESP) is designed for effective control of fine aerosol from humid gases, which operates on the principle of unipolar particle charging in the corona discharge and particle precipitation under their own space charge.

Review on water electro-sprays and applications of charged drops with focus on the corona-assisted cone-jet mode for High Efficiency Air Filtration by wet electro-scrubbing of aerosols
TL;DR: In this paper, the authors present the physical constraints to achieve steady water electrospray in ambient air to account for Electro-Hydro-Dynamic equilibrium required for the cone and jet formation on the one hand and to control electrical discharges in the gas around the liquid (with continuous corona or without any discharge).

Electrostatic spraying of liquids in cone-jet mode
M. Cloupeau,B. Prunet-Foch +1 more
TL;DR: In this paper, a cone-joint burst of a permanent jet extending from a volume of liquid in conical form is investigated, and it is shown that the energy minimization principle cannot be applied to this type of atomization; the ratio of the drop charge to Rayleigh limit charge varies greatly, depending on conditions.

Corona from a Water Drop
TL;DR: In this article, the luminosity obtained with a negative drop point and the complex oscillograph pulses on both polarities have been accounted for by considering positive corona from charged droplets leaving the water point and assuming that true negative Corona from a water surface is impossible.

Electrostatic Pesticide Spraying: Concepts and Practice
TL;DR: In this article, the system requirements and characteristics necessary for the design and development of electrostatic-spraying machines uniquely adapted to agricultural pesticide applications are presented, and the fundamental approach utilizes an electrostaticinduction nozzle to atomize pneumatically the spray (e.g., 30-50?m volume median diameter (VMD)) and to charge the conductive liquid typically to a?10-mC/kg.

C. W. Lear,W. F. Krieve,E. Cohen +2 more
TL;DR: In this paper, a charged droplet scrubber using electrohydrodynamically sprayed droplets and an applied field to achieve electrical impact scrubbing is described, and it is shown that such scrubbers are capable of high densities of droplets in the 100 jum size range and charged to near their upper stability limit.
