Description
Technical field
The present invention relates to a kind of electro-galvanizing liquid automatic allocating and updating system, be applied to be with in the zinc-plated production unit of steel continuous electric.
Background technology
In the zinc-plated unit of band steel continuous electric, it is the subject matter that is perplexing traditional mode of production that waste water that produces in the electro-galvanizing production process and electroplate liquid are eliminated always, and the wastewater flow rate that traditional electrical zinc-plated (adopting alkaline cyanide plating bath, alkaline phosphate plating bath, chlorination system, fluoroborate system etc.) produces is big, waste water is difficult and cost is high.Adopted vitriol system-solution of zinc sulfate in recent years in the world, be that sulfuric acid dissolution zinc or ways such as dissolving zinc sulfate etc. obtain electroplate liquid (zinc sulfate) and realize electro-galvanizing, although the waste liquid of vitriol is easily handled, but because equipment or configuration reason, such production unit still has a large amount of waste water to produce at present.
In present Electroplating Production, divide soluble anode and soluble anode, soluble anode have quality good, stablize easy to control, speed advantages of higher, shortcoming: many, the system complex of waste water.Soluble anodization production does not realize the infinite loop of Electroplating Production, for electroplating quality, can only discharge the water that contains useful material in a large number even regularly discharge electroplate liquid.And the good several conditions of electroplating quality are: electroplating bath components, temperature-stable, impurity is few.
Summary of the invention
The object of the present invention is to provide a kind of electro-galvanizing liquid automatic allocating and updating system, guaranteed the stable of electroplate liquid quality, realized the continuous electroplating non-wastewater discharge, just zero release.
Technical scheme of the present invention is: electro-galvanizing liquid automatic allocating and updating system, provide electroplate liquid to plating tank, it is characterized in that: it comprises electroplate liquid dissolving/configuration-system, filtering system, vacuum concentration separation system, the recycle system and electroplate liquid receiving tank, wherein filtering system comprises grade one filter, secondary filter, tertiary filter and by-passing filter device again, the vacuum concentration separation system comprises the vacuum concentration separator, and the recycle system comprises that electroplate liquid upgrades recycle pump, concentrated solution supply pump, electroplates circulation solution feed pump and band steel spray water supply pump;
Electroplate liquid circulates through following equipment successively: electroplate liquid dissolving/configuration-system, grade one filter, electroplate liquid receiving tank, plating circulation solution feed pump, plating tank, secondary filter, electroplate liquid receiving tank, electroplate liquid upgrade recycle pump, tertiary filter, vacuum concentration separator, concentrated solution supply pump, electroplate liquid dissolving/configuration-system; The vacuum concentration separator is connecting band steel spray water supply pump simultaneously, and the electroplate liquid receiving tank connects the by-passing filter device simultaneously.
Principle of work of the present invention is: the present invention is by electroplating the circulation solution feed pump and being with steel spray water supply pump to supply with electroplate liquid and giving plating tank and rinse-system, steel band is before plating, in the plating and the de-salted water rinsing of plating back, in plating tank, electroplate, it must be clean entering galvanized belt steel surface, so clean before plating is arranged, between plating tank, also want water to guarantee that the band steel cleans or preserves moisture, and also will clean the plating bath attached to surface of steel plate after the plating.
Electroplate liquid dissolving/configuration-system: at first solving zinc is the at first production that guarantees electroplate liquid, is to guarantee Zn in the electroplate liquid
2+Key, electroplate stable carrying out, dissolving also must be stablized and be carried out, electroplate liquid dissolving/configuration-system dissolves zinc granule with dilute sulphuric acid or vitriolated solution of zinc sulfate, guarantees stable electroplate liquid concentration.
Band steel continuous high speed electro-galvanizing is a systems engineering, the process of a complexity.Guarantee the stable of electroplating bath components, plating is exactly that metal ion is deposited on surface of steel plate, and metal ion reduces in the electroplate liquid, the acid enhancing, and electroplate liquid is dissolving zinc granule always simultaneously, the acid enhancing, dissolution rate must be accelerated; In whole process, must there be impurity to be brought into, strict filtering system must be arranged, be used for filtering the impurity or the particle of electroplate liquid.
When electroplating, owing to clean and be with preserving moisture of steel between conductive rollers or the plating tank, there is a large amount of water to enter into electroplate liquid before and after the plating, portion water be separated, in order to guarantee stable electroplate liquid concentration, the system that also has a vacuum-evaporation concentrating and separating water is as assurance, need concentrate electroplate liquid, could guarantee the concentration stabilize of electroplate liquid, stable electroplating bath components is the necessary condition that guarantees electroplating quality, and the vacuum concentration separator is the stable electrical solution composition and recovers SO
4 2+Active key equipment.High current density (＞100A/m
2), require ZnSO in the electroplate liquid
4Composition is in stable high-content level.
The invention has the beneficial effects as follows: each system's reasonably optimizing configuration of the present invention; regularly take out the strainer foreign material; by the vacuum concentration separation system; the electroplate liquid that has diluted is separated water outlet and thereby dense electroplate liquid is realized cleaner production; also recovered the activity of electroplate liquid,, need not regularly electro-galvanizing liquid to be upgraded so electroplate liquid can use again and again; non-wastewater discharge has effectively been protected environment.
Supply with electro-galvanizing liquid by the present invention and give plating tank and rinse-system, electroplate liquid is being electroplated, is filtering, is being concentrated and the continous-stable operation of dissolution process etc., simultaneously sulfate ion SO
4 2-More stable, easily recover its activity, be convenient to recycling, guaranteed the stable of electroplate liquid quality.
