CHARGING DEVICE AND DUST COLLECTING APPARATUS

The present disclosure relates to an electrostatic charger and an electrostatic precipitator capable of securing a wide space for charging suspended fine particles contained in a processing airflow, compared to a case in which a discharge electrode is configured to be disposed on an upstream side of the processing airflow further than an end portion of the ground electrode on the most upstream side of the processing airflow.The electrostatic charger includes a discharge electrode formed of a plurality of fibrous conductors and provided to generate and diffuse ions by a discharge, and a ground electrode maintained at a ground potential and provided to attract the ions generated and diffused by the discharge electrode to charge suspended fine particles contained in a processing airflow by the ions, wherein the discharge electrode is disposed between the ground electrodes in the processing airflow, and all or at least a part of the plurality of fibrous conductors of the discharge electrode are disposed on a downstream side of the processing airflow further than an end portion of the ground electrode on the most upstream side of the processing airflow.
