Abstract
The utility model relates to a device for recovering and treating waste liquor produced during the surface treatment of an electric conductive copper bar, a contact terminal and the like, in particular to a device for treating copper conductor pickle liquor. The device comprises a reaction tank, wherein the reaction tank is connected with a pickle liquor trough through a liquor feeding pipeline and a liquid inlet pump, and is connected with a pressure filer through a liquor discharging pipeline and a liquid outlet pump; an aeration pump is arranged outside the reaction tank, and is connected with an aeration pipeline leading to the bottom of the reaction tank; and an alkali storage trough capable of storing alkali liquor is also arranged outside the reaction tank, and is led to the reaction tank through an alkali liquor pipeline. The device has the advantages that the structure is simple; the operation is convenient; the running efficiency is high; alkali-adding neutralization and aeration oxidization can be conducted on the pickle liquor, so as to solidify copper ions in the pickle liquor into compounds for separation, improve the utilization ratio of copper, and reduce emission pollution.
Description
Technical field
The utility model relates to the device and method that a kind of waste liquid that electric power conducting copper, contact etc. are carried out producing in the surface treatment process recycles, and specifically is a kind of copper conductor spent pickle liquor treatment unit.
Background technology
Conductors such as the copper busbar that in power equipment, uses, copper contact need carry out pickling to remove surface and oil contaminant and zone of oxidation before installation, guarantee to install the safety that the back conduction connects.The pickle solution that copper conductor is carried out pickling along with the reaction consumes of acid, becomes waste liquid after pickling repeatedly, contain a large amount of cupric ions in this waste liquid, and directly discharging not only can pollute in this way, has also wasted a large amount of metals resources.
Summary of the invention
The utility model technical problem to be solved is, the copper conductor spent pickle liquor treatment unit and the treatment process that provide a kind of and can handle the copper conductor spent pickle liquor, copper raw material is wherein recycled.
The copper conductor spent pickle liquor treatment unit of the utility model includes a reaction tank, and reaction tank is connected with the spent pickle liquor groove with liquid feeding pump through input duct, and reaction tank is connected with a pressure filter with Pump for giving-out through the fluid pipeline; The reaction tank outer setting has aeration pump, and aeration pump is connected with the aerated conduit that feeds the reaction tank bottom; The reaction tank outside also is provided with the storage alkali groove that can store liquid caustic soda, and storage alkali groove feeds reaction tank through the alkali lye pipeline.
The utility model is simple in structure, easy to operate, operational efficiency is high; This device can be through adding alkali neutralization and aeration oxidation to spent pickle liquor; Make the cupric ion in the spent pickle liquor to solidify separation, improved the utilization ratio of copper product, reduced exhaust emission with the form of compound.
Description of drawings
Fig. 1 is the structural representation of the copper conductor spent pickle liquor treatment unit of the utility model.
Embodiment
As shown in the figure, this copper conductor spent pickle liquor treatment unit includes a reaction tank 1, and reaction tank is connected with spent pickle liquor groove 4 with liquid feeding pump 3 through input duct 2, and reaction tank is connected with a pressure filter 7 with Pump for giving-out 6 through fluid pipeline 5; The reaction tank outer setting has aeration pump 8, and aeration pump is connected with the aerated conduit 9 that feeds the reaction tank bottom; The reaction tank outside also is provided with the storage alkali groove 10 that can store liquid caustic soda, and storage alkali groove feeds reaction tank 1 through the alkali lye pipeline.
Utilize above-mentioned copper conductor spent pickle liquor treatment unit that spent pickle liquor is handled, concrete steps are:
A. close the fluid pipeline, the copper conductor spent pickle liquor in the spent pickle liquor groove is added reaction tank through liquid feeding pump; Start aeration pump bubbling air in reaction tank, waste liquid is carried out aeration; The major ingredient of spent pickle liquor is nitric acid, cupric nitrate and water, and other zwitterion is less.
B. under the situation that waste liquid stirs in reaction tank, add liquid caustic soda, carry out neutralization reaction through storage alkali groove; Be interrupted the adding liquid caustic soda, and in adition process the pH value of tank liquor in the detection at any time reactive tank, when pH value is 7.0+0.5; Stop to add alkali, produce blue copper sludge in the reaction tank this moment.
C. continue aeration, make copper sludge fully be oxidizing to copper sludge near black.
D. stop aeration, open the fluid pipeline, the mud in the reaction tank is fed pressure filter carry out press filtration, remove the part moisture in the copper sludge, obtain the copper sludge product; Its composition is mainly cupric oxide, verditer and water, can be used as industrial raw material.Copper content is more than 30% in the copper sludge after the press filtration.Content of copper ion is less than 0.5mg/L in the isolating water.
