Description

Acidity etching liquid recycling system
Technical field
The present invention relates to a kind of effluent purifying indirect regeneration, specifically refer to a kind of acidity etching liquid recycling system.
Background technology
Improvements along with electron trade, China's wiring board industry development is also broad-based recovery thereupon, according to < < 2009-2012 Chinese printing circuit-board industry developing foreground forecast analysis report > >, point out, China will become PCB industrial base the biggest in the world in recent years, accounts at present 30% left and right of world market.Simultaneously, Suining, Sichuan has been " southwestern circuit card (PCB) the industry manufacture base " that country examines at present, the PCB industry giants such as two places, Chongqing of Sichuan Founder Electronic, Foxconn's electronics enter, and coastal a large amount of circuit board plant is moved to the interior, and PCB industry will welcome huge business opportunity.
But, in the making processes of circuit card, such as operations such as printed circuit board, plating, all can produce a large amount of copper powders, shot copper and cupric ion at work, these copper powders, shot copper and cupric ion all need a large amount of cleaning water to clean, and copper-containing wastewater after clean contains a large amount of cupric ions, can not reuse, copper-containing wastewater enters also very inconvenience of sewage work's aftertreatment simultaneously, therefore, we need to design a kind of Waste Water Treatment, to solve copper-containing wastewater, process problem complicated, that can not recycle.
Summary of the invention
Problem to be solved by this invention is to provide a kind of acidity etching liquid recycling system, has solved the problem that acidic etching waste liquid processing is complicated, cost is high, have waste discharge.
Technical scheme provided by the invention is: acidity etching liquid recycling system, comprise the etching production line watering equipment, transfer mother liquor tank, mother liquor tank, acidity etching liquid recycling equipment group, the sub-flow container of regenerating, Agitation Tank, strainer, the sub-flow container that connect successively, between described two adjacent parts, be also connected with high-pressure pump.
Described acidity etching liquid recycling equipment group comprises three-way electrovalve door and two acidity etching liquid recycling equipment that are connected in parallel to each other, and two exit end of described three-way electrovalve door connect respectively two acidity etching liquid recycling equipment that are connected in parallel to each other.The effect of acidity etching liquid recycling equipment is mainly to utilize electrolysis principle, anode electrolysis system by acidity etching liquid recycling device interior is carried out electrolysis to mother liquor wherein, univalent copper ion in mother liquor enters the sub-flow container of regeneration after being oxidized to bivalent cupric ion, and the univalent copper ion that mother liquor in negative plate contains enters into copper powder recovery system after being reduced into copper, thereby reach the recycling of etching solution regeneration and copper.
Described acidity etching liquid recycling equipment group is also connected with copper powder and reclaims whizzer.Acidity etching liquid recycling equipment in acidity etching liquid recycling equipment group completes after electrolysis, copper-containing solution in its negative electrode is passed into copper powder and reclaims in whizzer, and the centrifugation that reclaims whizzer by copper powder has obtained electrolytic copper by the copper powder centrifuging in solution.
Described acidity etching liquid recycling system all adopts enclosed circulation structure.Each system, parts and the pipeline that described enclosed circulation structure refers to whole system is all in the enclosed construction in sealing, and extraneous impurity is difficult for entering internal system, can guarantee the safety and stability of system.
The invention has the advantages that: this acidity etching liquid recycling system of the present invention's design, efficiency is high, and cost is low, and floor space is few, without any discharge.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Label in figure is expressed as: 1, etching production line watering equipment; 2, transfer mother liquor tank; 3, mother liquor tank; 4, three-way electrovalve door; 5, acidity etching liquid recycling equipment; 6, copper powder reclaims whizzer; 7, acidity etching liquid recycling equipment group; 8, the sub-flow container of regenerating; 9, Agitation Tank; 10, strainer; 11, sub-flow container.
Embodiment
Embodiment 1
Referring to Fig. 1, technical scheme provided by the invention is: acidity etching liquid recycling system, comprise the etching production line watering equipment 1, transfer mother liquor tank 2, mother liquor tank 3, acidity etching liquid recycling equipment group 7, regenerate sub-flow container 8, Agitation Tank 9, strainer 10, the sub-flow container 11 that connect successively, between described two adjacent parts, be also connected with high-pressure pump.
Above-mentioned acidity etching liquid recycling equipment group 7 comprises three-way electrovalve door 4 and two acidity etching liquid recycling equipment 5 that are connected in parallel to each other, and two exit end of described three-way electrovalve door 4 connect respectively two acidity etching liquid recycling equipment 5 that are connected in parallel to each other.
Above-mentioned acidity etching liquid recycling equipment group 7 is also connected with copper powder and reclaims whizzer 6.
Above-mentioned acidity etching liquid recycling system all adopts enclosed circulation structure.
In use, etching production line watering equipment 1 used acidic etching waste liquid (being mother liquor) enters into acidity etching liquid recycling equipment group 7 by transfer mother liquor tank 2 and mother liquor tank 3, anode electrolysis by acidity etching liquid recycling equipment 5 is oxidized to bivalent cupric ion by the univalent copper ion in mother liquor, and by copper powder, reclaim the copper powder separation that whizzer 6 obtains acidity etching liquid recycling equipment 5 catholytes and obtain copper powder, etching waste liquor after electrolysis is the sub-liquid of regeneration, the sub-liquid of regenerating is inputted the sub-flow container 8 of regeneration successively, Agitation Tank 9, strainer 10 and sub-flow container 11, sub-liquid in sub-flow container 11 enters the interior formation etching solution of etching production line watering equipment 1 again and recycles, not only reclaim copper but also obtained newborn etching solution, cost, simultaneously, in the operational process of whole system, can not produce any objectionable impurities, environmental protection is practical.
Transfer mother liquor tank 2 and mother liquor tank 3 are for the temporary transient mother liquor that stores, the sub-liquid of regeneration that the sub-flow container 8 of regenerating generates for depositing acidity etching liquid recycling equipment group 7, Agitation Tank 9 is for adding ammonium chloride and the ammoniacal liquor of the sub-liquid internal loss of regeneration, strainer 10 impurity of being with during for the impurity in the sub-liquid of filter regeneration and dosing, sub-flow container 11 is for storing standby by sub-liquid.
After entering into acidity etching liquid recycling equipment group 7, mother liquor is communicated with three-way electrovalve door 4 inlet ends, two exit end of the three-way electrovalve door 4 respectively acidity etching liquid recycling equipment 5 in parallel with two are connected, when two exit end of three-way electrovalve door 4 are during all in open mode, two acidity etching liquid recycling equipment 5 are simultaneously in running order, now workload increases, the efficiency of whole system is improved, when two acidity etching liquid recycling equipment 5 is some when breaking down or need to clean, only need close corresponding three-way electrovalve door 4 outlets can allow it independently go out, now can carry out troubleshooting or cleaning to it, and another acidity etching liquid recycling equipment 5 is still in running order, need not stop whole system, this structure has not only been protected system, handiness and the security of whole system have been increased.
Can well realize the present invention as mentioned above.
