Abstract
The invention relates to an electrolysis system for producing electrolytic manganese dioxide. The system comprises an electrolyte preheating device and an electrolysis device, wherein the electrolysis device comprises a tank body, wherein an anode region enclosed by a diaphragm is formed in the middle of the tank body; a plurality of cathode regions are partitioned between the anode region and the tank body; electrolyte inside the preheating device is conveyed to each cathode region through a pump; an anode plate is inserted into the anode region; a cathode plate is inserted into each cathode region. The electrolyte is preheated in a concentrating manner, and then conveyed to each cathode region, so that the electrolyte inside the electrolysis device is quickly electrolyzed. Thus, the electrolysis efficiency is improved. Meanwhile, each cathode region adopts a stepped tank bottom; the cathode plates can be gradually started just by starting the cathode plates in the cathode regions to electrolyze when the electrolyte is led to the cathode region with the deepest tank bottom. Thus, the electrolysis cost is reduced. A heat-conducting oil heating device is also adopted to heat, so that not only can the heating temperature be accurately controlled, but also electrolytic products can be prevented from being polluted. Therefore, the product quality is improved.

Technical field
The present invention relates to prepare electrolytic manganese dioxide manganese, is the electrolytic system of producing electrolytic manganese dioxide specifically.
Background technology
At present, electrolytic manganese dioxide purity is high, crystal formation good, loading capacity is large, activity is strong, is good battery depolarizer, because it has good discharge performance, thereby becomes a kind of very important raw material of battery industry.It is H2SO4-MnSO4 electrolysis process that existing electrolytic manganese dioxide (EMD) production method adopted more.It is anode that this electrolysis process normally be take lead, lead 2-base alloy, graphite or pure titanium, titanium alloy, precious metal oxide coating etc., take graphite rod or stainless steel etc. is negative electrode, use manganese sulfate solution as electrolytic solution, pass to high-current low-voltage direct current and make divalent manganesetion on anode, lose electronics (generation oxidizing reaction) and finally separate out Manganse Dioxide.Be deposited on the thick product of Manganse Dioxide on anode through peeling off, after pulverizing, rinsing, neutralization, dry etc. processing, obtain electrolytic manganese dioxide finished product.
For reducing production unit cost, simplify production technique, improve electrolytic manganese dioxide quality product, promoting electrolytic efficiency consideration, in electrolytic process, toward contact, need to heat electrolytic solution.Conventional electrolytic solution heating means are that electrolytic solution heating tube is set in electrolyzer, pass into the saturation steam of 110～150 ℃ in electrolytic process, and the heat exchange by electrolytic solution heating tube makes the temperature of electrolytic solution remain on the scope of setting.Good heat conductive characteristic based on metallic copper, described electrolytic solution heating tube can consider to adopt copper pipe conventionally, yet, because the high-concentration sulfuric acid containing in electrolytic solution can accelerate the dissolving of copper under hot conditions, easily cause the damage that is corroded of copper heating tube; The more important thing is, if copper enters in electrolytic solution, by electrolytic manganese dioxide, adsorbed most probably and cause product contamination, and then reduce product quality.
Summary of the invention
For the shortcoming of above-mentioned prior art, the invention provides a kind of electrolytic system that can accurately control the production electrolytic manganese dioxide that Heating temperature, cost quality product lower, that produce is higher.
The present invention solves the problems of the technologies described above by the following technical solutions: a kind of electrolytic system of producing electrolytic manganese dioxide, comprise electrolyte preheating device and electrolyzer, described electrolyzer comprises groove body, the positive column surrounding for barrier film in the middle of groove body, between positive column and groove body, separate as several cathodic areas, electrolytic solution in primary heater unit is by pump delivery to each cathodic area, and positive column is inserted with positive plate, and each cathodic area is inserted with a negative plate.
Further, the bottom land between described positive column and groove body is stepped, and the cascaded surface of each ladder is the bottom surface in a cathodic area.
As preferably, described primary heater unit is a container, and container wall is provided with several drain pipes, and each drain pipe is communicated with cathodic area described in, on each drain pipe, be provided with one described in pump.
As preferably, in described container wall and groove body, be equipped with interlayer, heat-conducting oil pipes is installed in interlayer, the temperature of heat-conducting oil pipes is controlled by hot oil heater.
As preferably, described bottom land is provided with waste liquid relief outlet.
As preferably, described drain pipe is provided with thermal insulation layer.
The present invention compared with prior art tool has the following advantages:
1, the present invention, by electrolytic solution is concentrated and carried out preheating, is then delivered to each cathodic area, makes the electrolytic solution quick electrolysis in electrolyzer, improves electrolytic efficiency;
2, at the bottom of cathodic area adopts step type slot, when the darkest cathodic area of bottom land passes into electrolytic solution, the negative plate electrolysis in this district need only be started, starter cathode plate one by one can be realized according to this, thus lower electrolysis cost;
3, the present invention adopts hot oil heater heating, not only can accurately control Heating temperature, and can avoid polluting electrolytic production, thereby improve the quality of products.
