WIPO Patent Application WO/2020/085231

A1

This dust removal device comprises: at least one nozzle that is disposed in a blow-out part for blown air, is capable of spraying a supplied liquid in the form of droplets, and is connected to ground; an electrode part that includes a counter electrode which is shaped so as to surround at least half of the circumference of one opening, with one counter electrode provided for one nozzle, and with the counter electrode being disposed so as to be separated from the nozzle in the direction in which the nozzle sprays the droplets; and a high-voltage generation device that has a ground terminal connected to ground, and that is for applying a high voltage to the counter electrode which is connected to an output terminal. If a leakage current is not flowing between the nozzle and the counter electrode, the current flowing between the nozzle and ground is no greater than 0.3 milliamperes (square meters/liter per minute) for every 1 liter per minute of droplet spray and every 1 square meter of the opening surface area of the blow-out part.
