Embodiment 1
[0021] An electrolytic cell with uniform vertical inflow feeding, such as figure 1 , figure 2 , image 3 As shown, it includes an electrolytic cell body 1, a plurality of cathode plates 2, a plurality of anode plates 3, a solution channel I4, a solution channel II 5, a plurality of liquid inlet nozzles 6, a plurality of liquid outlet nozzles 7, and a rectangular Groove 8.
[0022] Such as image 3 As shown, the liquid inlet nozzles installed on the solution channel Ⅱ5 are respectively named #1 to #12 from left to right. In this embodiment, a single electrolytic cell is used as an object, and a total of 12 liquid inlet nozzles #1-#12 are used to feed liquid at the same time. On this basis, the orthogonal experiments with two factors and two levels were carried out. Among them, current density: 240 A / m 2 ,300A / m 2 ; Electrolyte flow rate: 11ml / min, 22ml / min. The period of each experiment is two days. After the experiment, ICP is used to detect and analyze the content of...
Embodiment 2
[0026] A total of 10 liquid inlet nozzles #2-#11 were used as solution inlets to feed liquid at the same time, and the condition experiment in Example 1 was repeated, and the analysis results are shown in Table 2.
