Description
[technical field]
The utility model relates to a kind of acidic etching liquid regeneration of processing and the copper recovery system of water, waste water or the sewage of extraction process, refers to a kind of acidic etching liquid regeneration and copper recovery system especially.
[background technology]
Etching work procedure in the wiring board manufacturing process is one important procedure that wiring board is made,, the waste liquid that produces in this operation process is a kind of high-copper waste liquid [a cupric 110-160 grams per liter].To this etching waste liquor, current at present way is to have the recovery company of qualification to pull away waste liquid by the locality, and the copper that uses chemical process (neutralisation or substitution method) to reclaim in the waste liquid is then made copper sponge or copper sulfate.These method technologies fall behind, and copper reclaims not thorough, and the economic benefit of processing is not obvious, and the waste liquid of having carried behind the copper directly effluxes, and causes " secondary pollution ", and local water ecosystem is caused than havoc.
[summary of the invention]
The purpose of the utility model is to provide a kind of and can the acidic etching liquid that the complete cyclic regeneration of spent etching solution, the electrolytic copper product that can obtain high economic worth, no waste water and gas produce be regenerated and copper recovery system.
The utility model solves the technical scheme that its technical problem adopted: a kind of acidic etching liquid regeneration and copper recovery system is characterized in that: comprise first extraction tank and second extraction tank, said first extraction tank connects the etching waste liquor transfer lime; First extraction tank and second extraction tank are communicated with through first pipeline; Its top is respectively arranged with the extraction pipeline, and this extraction pipeline leads to the extraction water chamber wash, and the extraction water chamber wash is communicated with the back extraction chamber through second pipeline; Said back extraction chamber is passed through the 3rd pipeline and is communicated with transporting room; Transporting room is communicated with electrolyzer through the 5th pipeline through transferpump, and the top of back extraction chamber is provided with the back extraction pipeline, and this back extraction pipeline leads to back extraction washing chamber; The top of back extraction washing chamber is communicated with oil cylinder, and the regenerated etching solution is through the 4th pipeline loopback etching production line.
Said transporting room can have dividing plate, with the velocity of flow of buffering liquid, makes that the fluid density that gets into electrolyzer is more even, and the electrolysis that helps copper is carried out.
The beneficial effect of the utility model is: material is realized closed cycle in the entire treatment process, does not have waste water and gas to discharge, ability high efficiente callback copper, regeneration etching solution and ammoniacal liquor washing lotion.
[description of drawings]
Below in conjunction with accompanying drawing the utility model is done further to describe.
Accompanying drawing is regeneration of the utility model acidic etching liquid and copper recovery system synoptic diagram.
Among the figure: 1 be first extraction tank, 2 be second extraction tank, 3 for etching waste liquor transfer lime, 4 be the 4th pipeline, 5 be first pipeline, 6 for the extraction pipeline, 7 for extraction water chamber wash, 8 be second pipeline, 9 for the back extraction chamber, 10 for electrolyzer, 11 for the back extraction pipeline, 12 for back extraction washing chamber, 13 for oil cylinder, 14 be the 3rd pipeline, 15 for transporting room, 16 be that dividing plate, 17 is the 5th pipeline.
[embodiment]
Referring to accompanying drawing, a kind of acidic etching liquid regeneration of the utility model and copper recovery system is characterized in that: comprise first extraction tank 1 and second extraction tank 2; Said first extraction tank 1 connects etching waste liquor transfer lime 3, the first extraction tanks 1 and second extraction tank is communicated with through first pipeline 5, and its top is respectively arranged with extraction pipeline 6; This extraction pipeline 6 leads to extraction water chamber wash 7; Extraction water chamber wash 7 is communicated with back extraction chamber 9 through second pipeline 8, and said back extraction chamber 9 is communicated with transporting room 15 through the 3rd pipeline 14, and transporting room 15 is communicated with electrolyzer 10 through pipe 17 through transferpump; The top of back extraction chamber 9 is provided with back extraction pipeline 11; This back extraction pipeline 11 leads to back extraction washing chamber 12, and the top of back extraction washing chamber 12 is communicated with oil cylinder 13, and the regenerated etching solution is through the 4th pipeline 4 loopback etching production lines.
Said transporting room 15 has dividing plate 16, with the velocity of flow of buffering liquid, makes that the fluid density that gets into electrolyzer is more even, and the electrolysis that helps copper is carried out.
[0012] extraction agent that under acidic conditions, in high cupric spent etching solution, adds copper of this acidic etching waste liquid regeneration and copper recycling and processing device the copper in the cupric spent etching solution is carried out the secondary selective extraction, and the copper liquid of separating forms highly purified copper through electrolysis; Whole process is individual all to adopt closed circuit circulatory system, does not have secondary pollution, has realized the zero release of pollutent; Realize making full use of of resource; The protection environment, and can obtain good economic benefits, easy to operate simple.The copper extractant entering extraction water chamber wash 7 that contains that carries out after copper separates carries out the water cleaning; Remove the Ammonia impurity in the extraction agent; Get into back extraction chamber 9 then and carry out back extraction, make it to be converted into copper-bath and get into electrolyzer 10, electrolysis makes it to form copper content at the electrolytic copper more than 99.5%.Extraction agent after the back extraction gets into back extraction washing chamber 12 to carry out water and cleans, and removes to get into oil cylinder 13 in the extraction agent behind the contained copper sulfate and remake and recycle.
