The key of the process is an oxidation tank, a washing tower, water treatment and drying equipment. Wherein, reverse osmosis equipment and ion exchange equipment are usually adopted during water treatment; the oxidation tank typically utilizes a titanium-lined plate high-efficiency stirred tank or rubber lining; the scrubber typically utilizes a multi-stage counter-current scrubber; the drying equipment adopts pressure spray type, centrifugal spray type and chamber type drying.
However, Mn in the prior art3O4The production processes often adopt a discontinuous circulation mode, manual operation is needed, and a one-to-one mode is adopted among the processes, so that the production efficiency and the equipment utilization rate are greatly reduced.
