Abstract: An electrostatic purification device includes a purification tank housing configured to accommodate a fluid, a first electrode and a second electrode provided in the purification tank housing, a direct current (DC) power supply configured to apply a DC to the first electrode and the second electrode, a controller configured to monitor a current density between the first electrode and the second electrode, and determine whether purification is completed based on the current density, a first valve configured to control an introduction flow of the fluid into the purification tank housing, a second valve configured to control a discharge flow of the fluid from the purification tank housing, and a heat exchanger configured to cool the fluid accommodated in the purification tank housing.
