[0002] When an electroplating production line electroplates workpieces, a large amount of harmful gases will be generated in the electroplating workshop, and the electroplating workshop needs to be ventilated. During ventilation, the harmful gases in the electroplating workshop are first sucked into a scrubbing tower by an exhaust fan for treatment, and the treated air is discharged to the outside. At the same time, a fresh air fan sucks the outside air into a fresh air cabinet, and a filter cotton and a filter bag filter the dust in the air. The filtered air will enter the electroplating workshop through a fresh air duct and an air inlet window.

[0003] For example, CN212881687U discloses an electroplating environment ventilation system, including an electroplating production line.
