Description
Technical Field

Background
The evaporative crystallization device is widely applied to the industries of chemical industry, food, light industry, pharmacy, environmental protection, energy, new materials and the like at present. Calcium-magnesium scale and salt scale are frequently formed in the operation process of the evaporation crystallization device, the evaporation crystallization device needs to be shut down periodically and the evaporation device needs to be cleaned manually, and a series of cleaning problems such as high cleaning frequency, high cleaning difficulty, incomplete cleaning and the like always troubles the whole evaporation industry. The main reasons for the generation of calcium-magnesium scale and salt scale in the evaporative crystallization device are as follows:
firstly, the water contains Ca due to the different conditions of the materials in the water2+、Mg2+Isocation and SO4 2-、CO3 2-And calcium carbonate, calcium sulfate salt and the like which are composed of the ions can be supersaturated due to the change of concentration and temperature to be crystallized and separated out, and generate scale solids on the half piece of the plate heat exchanger, in the circulating pipeline, in the heating pipe of the heat exchanger and on the inner wall of the crystallizer or the separator, so that the heat exchange efficiency is influenced slightly, the plate fins and the heat exchange pipe are blocked seriously, and the normal operation of the evaporative crystallization device is seriously influenced. Wherein the solubility of calcium sulfate is not large, and the solubility is specially increased and then decreased, for example, the solubility is 0.1928g/(100g H) at 10 DEG C2O), the solubility is reduced to 0.1619g/(100g H) at 100 DEG C2O) when the temperature is more than or equal to 40 ℃, the temperature is changed along with the temperatureThe solubility of the calcium sulfate is increased to show a descending trend, and the change of the solubility ensures that the concentration of the calcium sulfate is easy to approach saturation when the material water in the heat exchange tube of the heater is heated in the circulating evaporation process, and the calcium sulfate is easy to crystallize and separate out at the wall surface to generate calcium scale.
Secondly, when the operation control is improper or the instrument is in fault during the evaporation process during production, the phenomena of false liquid level and low liquid level appear in the crystallizer or the separator, when heating steam (raw steam or MVR secondary steam) is still conveyed according to the steam supply amount during normal evaporation, the static liquid level pressure at the outlet of the heating pipe is very easy to cause, the material subjected to heat exchange by the heat exchange pipe is originally boiled above the liquid level of the outlet of the heating pipe, and the material is boiled in the heating pipe due to the insufficient static liquid level pressure, so that salt is inevitably crystallized and separated out, and salt scale and calcium magnesium scale are formed by the attachment of the heating inner wall.
