Chemical crystallizer

Abstract

The invention relates to the technical field of chemical production crystallization, in particular to a chemical crystallizer which comprises a device shell, a partition plate vertically extends out of the bottom face of the inner side of the device shell, a plurality of heating plates are fixedly installed on the outer surface of one side of the partition plate, and a discharging structure extends out of the position, corresponding to the lower portions of the heating plates, of the lower end face of the device shell. A n inclined temporary storage box is fixedly installed at the upper end ofthe device shell, and the end, away from the heating plate, of the temporary storage box is located below the height of the other end of the temporary storage box. According to the device, heat generated by heating evaporation is used for preheating liquid stored in the temporary storage box, and therefore heating energy consumption is reduced in the subsequent process that the liquid enters thedevice shell through the communicating pipe and then is heated; meanwhile, in the process of cooling and separating out the liquid on the inner side of the device shell, condensed water generated after steam releases heat is used for absorbing heat of the liquid on the inner side and is sent out, the cooling and separating-out process is accelerated, and then the crystallization efficiency is effectively improved.

Description

technical field [0001] The invention relates to the technical field of chemical production crystallization, in particular to a chemical crystallizer. Background technique [0002] In the chemical production process of potassium chloride, the potassium chloride solution needs to be heated and evaporated, and then the liquid is cooled to precipitate crystals to obtain crystals. In the prior art, the evaporation chamber, separation chamber, heating chamber, and circulation pipe To realize the steps of cyclic heating, evaporation, and precipitation of a certain amount of potassium chloride liquid, the entire precipitation process is relatively slow and time-consuming, which is embodied in the slow heating process and slow cooling process, and the heat taken away by evaporation is in the prior art If it is not utilized reasonably or to a large extent, the entire crystallizer is not conducive to efficient crystallization production, and the efficiency needs to be improved.
