Claims (1)

Электролитический способ регенерации травильных растворов на основе хлоридов железа, включающий подачу отработанного травильного раствора из ванны травления в электролизер, имеющий анодное и катодное отделения, разделенные ионообменной мембраной, окисление хлористого железа (FeCl2) в хлорное (FeCl3) в анодном отделении и восстановление железа - в катодном, возвращение регенерированного раствора в ванну травления, отличающийся тем, что перед подачей в электролизер, отработанный травильный раствор разделяют на два потока, каждый из которых подают в катодное и анодное отделения, разделенные анионообменной мембраной, при этом объем потока, подаваемого в катодное отделение, относится к объему потока, подаваемому в анодное отделение, как (1-3): 20, после электролиза анолит и католит смешивают, после чего возвращают в ванну травления.An electrolytic method for the regeneration of pickling solutions based on iron chlorides, including supplying the spent pickling solution from the pickling bath to an electrolytic cell having an anode and cathode compartments separated by an ion exchange membrane, oxidizing ferric chloride (FeCl 2 ) to chloric (FeCl 3 ) in the anode compartment and reducing iron - in the cathode, returning the regenerated solution to the pickling bath, characterized in that before being fed to the electrolyzer, the spent pickling solution is divided into two streams, each of which fed to the cathodic and anodic compartments separated by an anion exchange membrane, the volume of flow supplied to the cathodic compartment refers to the volume of flow supplied to the anodic compartment, as (1-3): 20, after electrolysis, the anolyte and catholyte are mixed, and then returned into the pickling bath.
