Description
Technical field
The present invention relates to the chemical combination in a kind of electrolytic manganese process and efficient filter-pressing device.
Background technology
Electrolytic manganese carries out by manganese ore pulverizing, chemical combination, removal of impurities, carries out the hydrometallurgy process of electrolysis after allotment again, and wherein chemical combination is exactly, in chemical combination bucket, manganese mineral powder pulp is added the process that sulfuric acid carries out chemical reaction.Chemical combination can obtain solubility manganous sulfate, is convenient to the electrolysis procedure carrying out the later stage.
At present; the chemical combination bucket volume of commercial application can reach hundreds of cubes, needs, to blasting air in chemical combination bucket to the spilling of the oxygenolysis and part obnoxious flavour material that realize some impurity, to be both conducive to protection of the environment in chemical combination process; also realize electrolytic solution to refine, be conducive to the efficient electrolysis in later stage.
But chemical combination bucket blasts air carries out removal of impurities reaction by the less conditionality of concentration of oxygen gas, so generally take mass flow air to blast in actual applications, and take multitube chemical combination bottom of the barrel to import accelerating oxidation effect, but also there is large, the inefficient defect of energy consumption.Therefore, the dissolved oxygen ability improving chemical combination bucket seems extremely important.
Need after chemical combination completes to remove solid slag by press filtration, to obtain the solution needed for electrolysis.Therefore, press filtration is also very important unit step in electrolytic manganese process.
Press filtration in electrolytic manganese process, general is all plate and frame(type)filter press, and select impeller pump as filter pressing pump, pressure-filtering process obtains filtrate, filter residue progressively runs up to optimal filling degree in pressure filter simultaneously, carry out respective handling again, finally complete the cyclical operation process of filter residue cleaning, the object of press filtration realizes solid-liquid separation exactly.In the starting stage of press filtration operation, owing to being complete empty in pressure filter, concerning filter pressing pump, the quick large discharge input carrying out less lift is the ideal operation state of now press filtration operation; But increase along with filter cake accumulates rear resistance in pressure filter, when particularly stopping close to press filtration, have peak pressure expanded state, therefore, larger lift can be had to be to best requirement by the press filtration performance of pressure filter in press filtration the second half.
But in press filtration operation, existing impeller pump all cannot adapt to such process automatically, reaches efficient, high-quality ideal operation state.When general impeller pump carries out press filtration operation, be all that the early stage lift of press filtration is lower, but flow is large, makes motor be in overload, especially easily motor damage; To the press filtration middle and later periods, press filtration resistance strengthens rapidly, and the flow quantity of impeller pump reduces rapidly, although at this moment motor is operated in the low power state of underloading, efficiency of press filtering is very low; Although filter pressing pump has H-Max output state, because pressing filtering liquid flow is less, the serviceability of pressure filter cannot be given full play to and increase work efficiency.
Therefore, impeller pump is made to coordinate pressure filter, the press filtration whole process in electrolytic manganese process is made all to reach ideal operation state, the optimum performance playing press filtration is difficult to realize, if but look for another way, adopt the free shifter of two impeller pump series and parallels to complete press filtration work, make it in press filtration in early days by two impeller pump parallel connections, realize fast, less energy-consumption, the efficient press filtration of large discharge; In press filtration, two impeller pumps are connected by latter stage, obtain high-lift transport capacity, after meeting, journey press filtration resistance is large, but still applicable flow can be had to embody efficient press filtration and give full play to the feature of pressure filter performance, so free shifter of two impeller pump series and parallels is adopted to break through pressure filtering technique bottleneck in electrolytic manganese process, reach the ideal operation state of press filtration, there is the actual application value of particularly important.
