Claims

1. A system for acid etching of a strip with inductive hydrogen control, including an acid etching bath, characterized in that at least one inductor is installed on said acid etching bath, said inductor has an air inlet, an air supply opening and an air return flow opening, wherein said air inlet opening is connected to an air supply pipeline, and said air supply opening and said air return flow opening are connected to the cavity of the acid etching bath, at least part of the air return flow openings of the inductors are located opposite the hydrogen accumulation zones in the acid etching bath.

2. A system for acid etching of a strip with inductive hydrogen control according to paragraph 1, characterized in that a first layer of adsorbent is installed in the return air channel of the inductor.

3. A system for acid etching of a strip with inductive hydrogen control according to claim 2, characterized in that the first layer of adsorbent is made of SDG adsorbent or activated carbon.

4. A system for acid etching of a strip with inductive hydrogen control according to paragraph 2, characterized in that a second layer of adsorbent is additionally installed in the return air channel of the inductor, which is located below the first layer of adsorbent.

5. A system for acid etching of a strip with inductive hydrogen control according to claim 4, characterized in that the second layer of adsorbent is made of an adsorbent capable of adsorbing hydrogen.

6. A system for acid etching of a strip with inductive hydrogen control according to any of paragraphs 1-5, characterized in that a third layer of adsorbent is installed in the air supply channel of the inductor.

7. A system for acid etching of a strip with inductive hydrogen control according to claim 6, characterized in that the third layer of adsorbent is made of an adsorbent capable of adsorbing hydrogen.

8. The system for acid etching of the strip with inductive hydrogen control according to claim 1, characterized in that: a jet stream of air exiting from the air supply opening is directed towards the hydrogen accumulation zone, designed to push hydrogen from the acid etching bath to the exhaust opening; and / or a jet stream of air exiting from the ventilation opening is directed around the hydrogen accumulation zone to create a negative pressure effect for suction into the hydrogen accumulation zone.

9. A system for acid etching of a strip with inductive hydrogen control according to claim 1, characterized in that said supply gas pipeline is designed to supply an inert gas.

10. A method of using an acid strip pickling system with inductive hydrogen control as specified in any of paragraphs 1-9, characterized in that it includes: checking the hydrogen concentration in the acid pickling bath; when the hydrogen concentration in the bath reaches a set threshold, the inductor begins to operate to reduce the hydrogen concentration in the bath.
