Embodiment
Below will in graphic exposure multiple enforcement mode of the present utility model, as clearly stated, the details in many practices will be explained in the following description. It will be appreciated, however that the details in these practices is not applied to limit the utility model. That is, in part enforcement mode of the present utility model, the details in these practices is non-necessity. In addition, for the purpose of simplicity of illustration, some known usual structures and assembly illustrate it by the way of simply illustrating in the drawings.
Refer to shown in Fig. 1, its one or more than one reactive tank 10 in fill copper metal particle 110, and discharge port 120 is set in reactive tank 10 slightly top half portion place, and the first opening for feed 130 and the 2nd opening for feed 140 is set in bottom place. Above-mentioned 2nd opening for feed 140 is connected to plating tank 200, with by low-concentration sulfuric acid copper (CuSO remaining after carrying out electroplating reaction in plating tank 2004) and sulfuric acid (H2SO4) electroplating effluent be conveyed in reactive tank 10.
In addition, the first opening for feed 130 is connected to the ozone generation device 20 of peripheral hardware, and ozone supply is in reactive tank 10. Above-mentioned reactive tank 10 there is no specific restriction, can be general known conventional reactive tank 10.
Adopt the nitric acid stripping silicon liquid electrolysis cycle regenerating unit that this creation provides, it is mainly utilize ozone (O3) Strong oxdiative power, replace known hydrogen peroxide (H2O2) carrying out regeneration chemical reaction, its reaction formula is as follows: Cu+H2SO4+O3→CuSO4+H2O+O2。
Electroplating effluent is conveyed in reactive tank 10 via the 2nd opening for feed 140, utilize the first opening for feed 130 to be conveyed in reactive tank 10 by ozone manufactured in ozone generation device 20 simultaneously, the metallic copper make sulfuric acid contained in electroplating effluent, being filled in reactive tank 10, and ozone carries out above-mentioned chemical reaction, metallic copper is oxidized, and with sulfate radical (SO4 2-) combine and produce copper sulfate (CuSO4), then the copper sulfate produced is refluxed in plating tank 200, with the cupric ion (Cu reduced gradually in supplemental tank2+)。
In the regenerative response that this creation provides, sulfuric acid (H required in reactant2SO4), because copper sulfate (CuSO in the electrolytic solution4) after electroplating, bivalent cupric ion (Cu2+) metallic copper (Cu) will be reduced in negative electrode place, and the sulfate radical (SO of the mole numbers such as remnants4 2-), then with anode produce H+It is combined into sulfuric acid (H2SO4) kenel.Therefore, electroplating effluent itself just has the sulfuric acid (H of a great deal of2SO4), can not supplement separately and continue to react.
The electroplating effluent recycling device that this creation of above provides, except needn't using the hydrogen peroxide of high risk, still electroplating effluent can be reclaimed and carry out regenerative response, can not produce to drain in the problem of outer contaminate environment, not only can save raw materials cost, also can avoid perplexing plating industry liquid waste disposal problem for many years simultaneously, fully solve problem of environmental pollution.
Moreover, ozone required in the reactant of above-mentioned regenerative response formula, is can excite with electrode by ozone generation device 20 or after the effect such as ultraviolet produces ozone, then provides use in real time. Separately, it is increase to react the homogeneity that carries out, first by the electroplating effluent that reclaims and ozone, after carrying out Homogeneous phase mixing through mixing tank in advance, then can send in reactive tank 10, to increase the homogeneity of reaction simultaneously.
The preferred construction configuration of overall device, refer to Fig. 2, connecting fresh air breathing apparatus 210 at ozone generation device 20 utilizes fresh air breathing apparatus 210 to be directly transported in by oxygen in ozone generation device 20, and ozone generation device 20 can adopt electrode or ultraviolet generator to make ozone fast for use. Moreover, electroplating effluent recovery tube 150 and ozone supply pipe 160 are linked in mixing tank 170 simultaneously, after sufficiently mixing, are more on average conveyed in reactive tank 10 via feed distribution pipe 190, carry out regenerative response.
In addition, also can installing storage tanks 30 in discharge port 120 front end, will be stored in this through reacted high-concentration sulfuric acid copper, recycling is installed in the transfer lime 310 of storage tanks outside, and refluxes in plating tank 200.
Moreover, more smooth and easy for making regenerative response carry out, and the copper-bath concentration passed back in plating tank can improve more, this creation is provided another embodiment of electroplating effluent recycling device, refer to shown in the 3rd figure, these reactive tanks 10 above-mentioned are arranged on storage tanks 30 inner. The discharge port 120 of these reactive tanks 10 is designed to the most circular holes being centered around on reactive tank 10 periphery wall, and is arranged on half portion, make to protrude from the copper sulfate liquid level stored by storage tanks 30 inside.
The device provided in above-described embodiment is provided, the copper-bath in storage tanks 30 can be made to carry out the regenerative response circulated repeatedly, further increase the concentration that reaction is produced copper-bath.
Above nitric acid provided by the utility model being shelled silicon liquid electrolysis cycle regenerating unit to be described in detail, the explanation of above enforcement mode just understands structure of the present utility model for helping; Meanwhile, for one of ordinary skill in the art, according to thought of the present utility model, all will change in specific embodiments and applications.
