However, the prior art does not disclose Mn 3 O 4 Is combined with MES system.
There are many preparation methods of manganous oxide, and the preparation methods can be divided into the following steps from the aspects of reaction property and process characteristics: reduction, calcination, electrolysis and oxidation. The method for producing the manganous-manganic oxide in China mostly adopts an electrolytic metal manganese powder sheet suspension oxidation method, the raw materials of the method are electrolytic metal manganese sheets, firstly, the metal manganese sheets are crushed into suspension, and the manganous-manganic oxide is prepared under certain conditions by using an oxidant, and the basic process flow is as follows: pulping, oxidizing, drying and obtaining the finished product of the electrolytic manganese metal sheet. The key of the technology is an oxidation tank, a washing tower and water treatment and drying equipment. Wherein reverse osmosis equipment and ion exchange equipment are generally adopted in water treatment; the oxidation tank usually utilizes a titanium-lined plate high-efficiency stirring tank or rubber lining; the scrubber typically utilizes a multi-stage countercurrent scrubber; the drying equipment adopts pressure spray type, centrifugal spray type and box type drying. CN201410048579.9 discloses a device for preparing powdery MES particles by flexible process, which comprises a high shear reactor, a flash evaporation dryer, a cyclone separation device, a bag-type dust remover and a draught fan which are communicated in sequence through pipelines; the high shear reactor is horizontally arranged and is respectively provided with an acid ester inlet, a powder inlet, an air inlet and a material outlet communicated with the flash evaporation dryer; meanwhile, the patent also discloses a process which comprises the following steps: 1) The powdery mixture of the neutralizer, the wrapping agent and the stabilizer enters a high-shear reactor according to a certain proportion, and the fatty acid methyl ester obtained by sulfonating the fatty acid methyl ester also enters the high-shear reactor according to a certain proportion; 2) The materials stay for 10 to 60 seconds in a high shear reactor, and are subjected to neutralization reaction and wrapped to form MES particles; then the mixture is output from the high shear reactor and enters a flash dryer; 3) Outputting MES particles treated by the flash dryer, and then, entering a cyclone separator for cooling and drying; simultaneously, part of the coarser MES particles return to the high-shear reactor to be continuously further crushed, so that the obtained MES particles maintain a certain granularity; 4) The mixed gas flow from the outlet of the flash dryer enters a cyclone separator for separation, the separated powdery material directly enters a finished product powder bin, and the separated mixed gas flow enters a bag-type dust remover for dust removal and then is emptied; 5) Packaging MES particles in a finished product powder bin to obtain a finished product; and returning part of dust obtained by bag dust removal and separation to an inlet of the high-shear reactor for continuous reaction and granulation.
In the actual production process, the raw materials are wide in sources and different in types, and even though the main components of the raw materials are the same, parameters such as particle size, purity and the like may be different, so that the production process parameters are different, and in addition, the production process conditions are different due to different product requirements.
