Embodiment Construction
[0016] The specific embodiments of the present invention will be further described below in conjunction with the drawings:
[0017] As shown in the figure, a stepwise feeding method for nickel sulfate solution by negative pressure evaporation includes the following steps:
[0018] 1. Configuration solution: configure the nickel sulfate solution to be produced so that its concentration is 75-95g / L.
[0019] 2. Negative pressure evaporation: open the feed pipe valve switch, inject the nickel sulfate solution into the negative pressure evaporation device to the feed limit liquid level, close the feed pipe valve, turn on the heating device to heat the negative pressure evaporation device, and open the negative pressure pressure Table, start the vacuum machine, evacuate to -0.01--0.01MPa, keep it for about 1h, increase the liquid temperature to about 100℃, then reduce pressure so that the pressure maintained in the negative pressure evaporation device is maintained at 0.4MPa, and then 100...
