Detailed description of the invention
The present invention will be further described below in conjunction with the accompanying drawings, and protection scope of the present invention is not limited to the following stated:
As it is shown in figure 1, a kind of nickel retracting device, it includes waste liquid tank 1, filter A2, clean water tank 5 and acid solution tank A6, the storage of nickel liquid
Depositing tank 9, electrolysis unit 10, carry nickel device 11, the liquid outlet of described waste liquid tank 1 is connected with the inlet of filter A2, described
The outlet of filter A2 be provided with two arms, wherein arm connects has the first adsorption tower 3, another arm to connect to have the
Two adsorption towers 4, are provided with ion exchange resin in the first described adsorption tower 3 and the second adsorption tower 4, and ion exchange resin can
The quickly nickel ion in absorption waste water, the first described adsorption tower 3 and the waste liquid outlet of the second adsorption tower 4 are respectively connected with filtration
Device B7, the liquid outlet of filter B 7 is connected with waste water treatment plant 8, and described clean water tank 5 is inhaled with the first adsorption tower 3 and second respectively
Attached tower 4 connects, and clean water tank 5 is supplied from water toward the first adsorption tower 3 and the second adsorption tower 4, thus it is clear to realize ion exchange resin
Washing, described acid solution tank A6 connects with the first adsorption tower 3 and the second adsorption tower 4 respectively, and acid solution tank A6 is toward the first adsorption tower 3 and
In two adsorption towers 4, the sulphuric acid of supply 20%, carries out pickling to ion exchange resin, and nickel ion is combined with sulphuric acid, obtains nickel sulfate molten
