Research Progress of Electrostatic Spray Technology over the Last Two Decades

From the raindrops of lightning to atomized droplets used in many fields, research on electrostatic spray technology has both a natural basis and practical significance. The utilization of electrostatic spray technology has covered the biological, food, pharmaceutical, industrial, agricultural, chemical, and manufacturing industries. To provide comprehensive information about the technology, this review presents a typical electrostatic spray system in terms of its atomization mechanism, electrostatic spray modes, and several kinds of basic parameters. This review focuses on the applications of electrostatic spray technology in the fields of nanomaterial preparation, agricultural plant protection, wet flue gas desulfurization (WFGD), and fuel combustion. This paper comprehensively surveys already well-established or future potential applications of electrostatic spray technology.
