Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of potassium persulfate preparation, in particular to a potassium persulfate crystallization device. Background Art
[0002] Potassium persulfate chemical reagent is a white crystalline powder that is soluble in water but insoluble in ethanol. It has strong oxidizing properties and is commonly used as a bleaching agent, oxidant, and polymerization initiator. It absorbs almost no moisture, has good stability at room temperature, is easy to store, and has the advantages of convenience and safety.
[0003] The preparation of potassium persulfate generally uses ammonium sulfate and sulfuric acid to prepare an electrolyte, remove impurities and then perform electrolysis. HSO4 discharges at the anode to generate peroxydisulfuric acid, which then reacts with ammonium sulfate to generate ammonium persulfate. Potassium sulfate is then added for double decomposition reaction. After cooling, separation, crystallization and drying, the finished potassium persulfate is obtained. The crystallization stage is to evaporate and crystallize the prepared wet potassium persulfate.
[0004] Conventional equipment generally puts the prepared potassium persulfate into a heating dish for direct heating. At this time, the potassium persulfate has just been filtered through filter paper to remove most of the water, and it needs to be heated and evaporated. After the water is separated out, the potassium persulfate forms crystals. In order to ensure the uniformity of heating, the wet potassium persulfate needs to be spread evenly in the dish and stirred continuously. At the same time, proper observation is required during the stirring process to prevent agglomeration. It is difficult for conventional equipment to achieve the above steps purely mechanically.
