Description
Technical field
The present invention relates to copper sulphate production technical fields, more specifically, it relates to a kind of high purity copper sulfate production line.
Background technique
Etching waste liquor be in printed wiring board etching work procedure by chemical corrosion method dissolve copper during produced by
's.This kind of waste liquid such as without deal carefully with using will cause serious environmental pollution and great economic waste.It is domestic usual
Processing method be: extract the copper in acidic and alkaline waste etching solution, production basic copper chloride, copper sulphate, copper oxide or copper carbonate etc. produce
Product.The foreign ions such as iron, arsenic, lead are usually contained in etching waste liquor, these foreign ions often in copper products, cause
The copper products arrived are second-rate.For the copper products of high-purity, generally first acidic and alkaline waste etching solution can be refined respectively,
Wherein foreign ion is removed, then makes acidic and alkaline waste etching solution and alkali that neutralization reaction occur, basic copper chloride precipitating is generated, through further
After reaction, the products such as copper oxide, copper sulphate can be produced.
The Chinese patent that Authorization Notice No. is CN100467671C in the prior art discloses one kind from acidic etching liquid
The method for recycling hydrochloric acid and copper sulphate, successively comprises the steps of:
(1) hydrochloric acid is recycled
By acidic etching waste liquid in acidproof distilling apparatus, the concentrated sulfuric acid is then added, is heated to fluidized state and passes through distillation
Recycle hydrochloric acid, wherein the concentration of the concentrated sulfuric acid is 98% or 98% or more；The additional amount of the concentrated sulfuric acid is with copper ion in fairing
Based on content reacts required theoretical value with sulfuric acid completely, it is further added by 5~15%.
(2) copper sulphate is recycled
1. being dissolved in water to remaining residue after recycling hydrochloric acid, dissolve the copper sulphate in residue sufficiently, the additional amount control of water
It is being added the 30~70% of acidic etching liquid volume；
2. cupric sulphate crystal is precipitated by cooling in the temperature change using high temperature to low temperature, temperature change controls 50 ± 10 DEG C of models
It encloses；
3. being filtered and washed to obtain copper sulphate to cupric sulphate crystal body.
But above-mentioned copper sulphate production method recycles the useful resources in etching waste liquor using the simplest way of distillation,
So that the production method has the following deficiencies:
1, the sulfuric acid copper products of phase homogenous quantities are produced, evaporation energy consumption is higher；
2, the unstable product quality obtained, the amount assembled in mother liquor due to impurity in operational process is increasing, in product
The impurity taken out of is more and more；
3, due to needing that hot water is added, with prolonged running, technique can generate a large amount of copper-containing wastewater.
Thus, it is necessary to existing copper sulphate production line is improved, to improve while reducing production energy consumption
The purity of sulfuric acid copper products.
Summary of the invention
In view of the deficiencies of the prior art, the present invention intends to provide a kind of high purity copper sulfate, have back

It connects；The beater tub is connect with souring tank, and the third chemicals dosing plant is connect with acidification bucket；The discharge end and the of the acidification bucket
The connection of one equipment for separating liquid from solid.
By using above-mentioned technical proposal, the etching waste liquid of the copper ions of recycling is temporarily stored into bucket；By storage
When etching liquid is passed into filter device by pipeline, it can synchronize and excess of ammonia is added into pipeline using the first chemicals dosing plant
Water.This process can make the impurity such as iron ion form the precipitation of slightly solubility alkali, and removal is filtered in filter device.It is filled by filtering
The etching liquid for setting the impurity such as iron ions is directed to intermediate fluid bucket and keeps in.
The temporary etching liquid of intermediate fluid bucket is directed into neutralization device via pipeline, and can be added by the second chemicals dosing plant
Sodium hydroxide is neutralized, so that copper ion is precipitated in the form of Kocide SD.The material for neutralizing device discharge is containing a large amount of
The muddy mixture of liquid, the mixture of discharge, which is fed in filter press, carries out filters pressing.The waste liquid that filters pressing generates can converge
Otherwise processed after collection, the hydroxide copper sludge filtered are used as the raw material of subsequent processing.
The hydroxide copper sludge that filter press filters pressing obtains is added to beater tub, and suitable water is added, mixing is in suitable
The hydroxide copper sludge of concentration (280-350g/L).Then, hydroxide copper sludge is added in souring tank and is acidified.Utilize third
Suitable sulfuric acid is added into souring tank for chemicals dosing plant, and sulfuric acid is reacted with Kocide SD generates copper sulphate, the sulfuric acid being saturated
Copper solution, part of sulfuric acid copper are precipitated in the form of crystal.After the discharge of copper/saturated copper sulphate solution, the sulfuric acid in copper/saturated copper sulphate solution
Copper is precipitated rapidly, and copper sulfate crystal separation is got product copper sulphate with the first equipment for separating liquid from solid.First equipment for separating liquid from solid
It, can be with otherwise processed after isolated waste liquid collects.Souring tank preferably has the reaction kettle of heating function, can appropriate evaporation section
Moisture, so that the copper-bath concentration after acidification, in favor of crystal precipitation.
The copper in etching liquid can be effectively recycled using high purity copper sulfate production line of the invention, and obtain purity >=
96% high-purity sulfuric acid copper products.It is not necessary that a large amount of hot water are added in production process, wastewater discharge is low, and production energy consumption is low.
