System for Multi-Jet Electrospray using Coaxial Grooved Nozzle and Method for Electrospray for NonConducting Fluids with HighThroughputs

摘要

PURPOSE: A multi-jet mode electrostatic spray device for non-conductive liquid using a coaxial grooved nozzle, and a producing method of micro-droplets using thereof are provided to spray the non-conductive liquid in the high flow rate. CONSTITUTION: A multi-jet mode electrostatic spray device for non-conductive liquid using a coaxial grooved nozzle comprises the following: the grooved nozzle(10) including an inner nozzle and an outer nozzle; an inner flow supply unit(30) supplying the non-conductive liquid to the internal space; an inner flow rate controller(31) connected to the inner flow supply unit for controlling the flow rate of the non-conductive liquid a high voltage applying unit(40) applying the voltage to the non-conductive liquid; an external flow supply unit(50) supplying the non-conductive liquid into a separation space; and a controller(41) adjusting the voltage applied by the high voltage applying unit based on the flow rate of the non-conductive liquid.
