Problems solved by technology

[0003] In actual production, the treatment of passivating agents is generally to choose direct treatment, recycling or discharge, and cannot be recycled for secondary use, resulting in great waste
At present, the period for each production enterprise to replace the passivator is generally about one month, and the production cost is too high

Abstract

The invention belongs to the technical field of passivating agent treatment, and particularly relates to passivating agent regenerating and recycling equipment and method. The invention firstly provides the passivating agent regenerating and recycling equipment. The passivating agent regenerating and recycling equipment comprises a pipeline system, a water storage mechanism, a treatment mechanism and a power mechanism. The pipeline system is communicated with the water storage mechanism and the treatment mechanism, and the power mechanism is connected with the pipeline system; the pipeline system is responsible for ensuring and controlling the circulation of gas and liquid; the water storage mechanism is responsible for storing and taking liquid; the treatment mechanism is responsible for treating the passivating agent; and the power mechanism is responsible for providing one or more of electric power, water pressure and air pressure. According to the passivating agent regenerating and recycling equipment and method, the waste of passivating agent liquid medicine is reduced, most importantly, the period is prolonged from one month to one year or even two years, a large amount of agent cost is saved, and the enterprise cost is saved.

Description

technical field [0001] The invention belongs to the technical field of passivating agent treatment, and in particular relates to a passivating agent regeneration and reuse device and method. Background technique [0002] Passivation refers to the process of metal oxidation by strong oxidants or electrochemical methods to make the surface inactive, that is, passivation. It is a method to transform the metal surface into a state that is not easy to be oxidized and delay the corrosion rate of the metal. In the current electroplating and galvanizing process, an important process is the passivation process after the galvanized layer. In the passivation process, the galvanized parts are soaked in a tank equipped with a concentrated passivation agent. However, with the continuous passivation of the parts, the ions in the passivator tank will change, among which the zinc ions and iron ions will continue to increase, because the zinc and iron on the parts are dissolved by the acidic ...
