The valves 2, 5 and 7 are all manual valves or electromagnetic valves.
Further, the manganese sulfate solution oil and impurity removing device comprises a reaction tank body 101, wherein the lower part of the tank body 101 is conical, and the upper part of the tank body is cylindrical;
a liquid distribution pore plate 102, a degreasing felt 103 and a manganese powder layer 104 are arranged from the lower part to the upper part of the inner conical part of the tank body 101, and the liquid distribution pore plate 102, the degreasing felt 103 and an activated carbon layer 105 are arranged from the lower part to the upper part of the inner cylindrical part of the reaction tank body 101; the solution is subjected to liquid separation by a liquid distribution pore plate 102 and then is subjected to primary oil removal by an oil removal felt 103, and then the solution treated by the oil removal felt 103 enters manganese powder, and the manganese powder and H are mixed+Reacting to consume H in solution+Thereby increasing the pH of the solution, the reaction equation being: mn +2H+＝Mn2++H2In addition, most of impurity metal ions, such As impurities of Cu, Cr, Cd, Pb, Ag, Hg, As, Ni, Co and the like, can also be subjected to a displacement reaction with Mn with higher activity, so that the impurity metal ions are removed; using manganese powder to adjust pH and remove impuritiesThe mass ions and the manganese powder react to generate manganese ions, and other impurities cannot be introduced;
the solution reacted with manganese powder is subjected to liquid separation by a liquid distribution pore plate 102 and treatment by an oil removal felt 103, and then enters an activated carbon layer 105 for oil removal and particle impurity filtration.
Further, a manganese powder filling opening 11 is formed in the side wall of the reaction tank body 101 corresponding to the manganese powder layer 104, so that the manganese powder can be conveniently replaced; the top of the reaction tank body 101 is provided with an activated carbon layer filling opening 13, and the side wall of the reaction tank body 101 corresponding to the bottom of the activated carbon layer 105 is provided with an activated carbon layer discharging opening 12 so as to facilitate the replacement of the activated carbon.

Because most of the metal ions in the manganese sulfate solution are inert metal ions such As Cu, Cr, Cd, Pb, Ag, Hg, As, Ni, Co and the like, the replacement reaction rate of the metal ions with Mn is slow. Therefore, the time during which the manganese sulfate solution flows through the manganese powder layer 4 can be controlled substantially by controlling the flow rate of the manganese sulfate solution. Preferably, the initial flow rate Q of the manganese sulfate solution per minute0Can be controlled to be 0.24-0.48V/min (wherein V is the volume of the manganese powder layer), so that the flowing time of the manganese sulfate solution in the manganese powder layer 4 is controlled to be about 2.1-4.2 minutes, and the battery grade standard is achieved. In this example, the initial flow rate Q of the manganese sulfate solution per minute0The flow time of the manganese sulfate solution in the manganese powder layer 4 is controlled to be about 2.8 minutes by controlling 0.36V, namely 0.36V/min. It is understood that too fast a flow rate is not conducive to adequate reaction; the flow rate is too slow, which affects the production efficiency.

Further, when the manganese sulfate solution oil and impurity removing device 1 at the head end is selected as the first group of oil and impurity removing devices, the third valves 7 are in a closed state;
when the non-head end manganese sulfate solution oil and impurity removing device 1 is selected as the first group of oil and impurity removing devices, the third valves 7 on the connecting pipes 6 on the right side of the selected manganese sulfate solution oil and impurity removing device 1 are opened, and the rest of the third valves 7 are in a closed state.
The working principle is as follows:
for convenience of explaining the principle, each manganese sulfate solution oil and impurity removing device 1 is sequentially marked as a first-stage oil and impurity removing device, a second-stage oil and impurity removing device and a third-stage oil and impurity removing device from right to left; and each second valve 5 is sequentially marked as a second valve-1 and a second valve-2 from right to left.

when the first-stage oil and impurity removing device and the third-stage oil and impurity removing device are required to be combined, the valves 2 at the inlet and outlet ends of the first-stage oil and impurity removing device and the third-stage oil and impurity removing device are opened, and the second valve-2 on the connecting pipeline 4 adjacent to the third-stage oil and impurity removing device is in a closed state; the valves 2 at the inlet end and the outlet end of the second-stage oil and impurity removing device are in a closed state, and the second valve-1 on the connecting pipeline 4 adjacent to the second-stage oil and impurity removing device is in an open state; the third valve 7 is in a closed state;

During production, the metal impurity content, the pH value and the oil content of the manganese sulfate solution are detected by sampling from a storage tank regularly. Further, a threshold value can be set, and when the content of metal impurities or the pH reaches the set threshold value, the flow rate Q of the manganese sulfate solution per minute can be properly reduced1Wherein, 0.5Q0≤Q1＜Q0(wherein Q)00.24V/min). Proved by experiments, when Q is1Less than 0.5Q0In the meantime, the content of metal impurities is difficult to be reduced to the battery standard, which may be caused by coating the surface of manganese powder metal with oil or replaced metal part during the reaction process. The threshold value is that the pH value is less than 5, and the oil content is higher than 5 mg/L. If the flow Q of the manganese sulfate solution per minute is reduced1When the content of metal impurities in the manganese sulfate solution cannot be reduced, skipping the previous oil and impurity removing device, and using the restTwo steps are continued to produce, and the previous stage device is added with manganese powder; if the flow Q of the manganese sulfate solution per minute is reduced1And skipping the previous oil removal and impurity removal device when the oil content of the solution cannot be reduced, using the rest two devices to continue production, and cleaning or replacing the active carbon by the previous device.
Before and after the manganese sulfate solution is deoiled and decontaminated, the oil content can be reduced from 10mg/L to below 0.01mg/L, and impurities such As Cu, Cr, Cd, Pb, Ag, Hg, As, Ni, Co and the like can also reach the battery grade standard.
