摘要： A mist removing device, a controlling method thereof a mist removing system and a control element are provided, which relate to the field of mist removing technology. The mist removing device includes power supply module, electrode array and insulating layer. Electrode array and insulating layer are arranged on substrate in stacked manner in direction away from substrate. Orthographic projection of insulating layer onto substrate covers orthographic projection of electrode array onto substrate. Power supply module is connected with electrode array. Power supply module is configured to supply power to electrode array such that electrode array forms electric field to cause droplets in mist to converge under action of electric field, where mist is formed on side of insulating layer away from substrate. Mist on surface of substrate can be effectively removed.
