The application relates to the technical field of dust removal devices, in particular to a reinforced dust removal electric dust collector and electric dust removal system. A plurality of dust removal areas are arranged in the electric dust collector and are spaced apart along the airflow direction to process dust-containing gas in stages, so that the dust can be fully charged and captured when passing through each electric field. Even if part of the dust cannot be completely captured in the front-stage electric field, the dust can be efficiently separated through re-charging in the subsequent electric field. The overall performance of the electric dust removal device is significantly improved through the step-by-step optimization mode. At least one dust removal area is connected with a reinforced dust removal assembly. The assembly can further enhance the electric field strength or improve the particle charging effect according to the actual working condition requirements (such as dust properties, airflow speed, etc.). In this way, the shortcomings of the traditional electric dust removal device in processing high-concentration dust or difficult-to-capture particles can be compensated for, and the dust removal requirements in different scenes can be flexibly adapted to, so that the applicability and performance of the equipment are significantly improved.
