Beschreibung
Zusammenfassung:	The invention discloses a cold rolling acid pickling fast circulation energy-saving device and method and belongs to the technical field of acid regeneration and acid pickling equipment and technologies. The cold rolling and acid pickling fast circulation energy-saving device and method are used for cold rolling acid pickling and acid regeneration recycling. According to the technical scheme of the cold rolling acid pickling fast circulation energy-saving device and method, an absorption tower of an acid regeneration unit is connected with a regeneration acid tank and an acid tank of an acid pickling unit; the regeneration acid tank is connected with the acid tank of the acid pickling unit; the acid tank is connected with a Venturi preconcentrator and a waste acid tank; the waste acid tank is connected with the Venturi preconcentrator; regeneration acid generated by the acid regeneration unit is directly supplied to the acid pickling unit for acid pickling work, and meanwhile waste acid generated by the acid
