摘要： A device for creating hollow tubes of crystalline magnesium sulphate sized a micron pertains to the production technology for inorganic micron-scale materials. The device consist of two halogenation tanks, a solar collector, a temperature-controlled crystallization chamber, a centrifuge, a conveyor belt, and a dryer. The solar collector is connected to a heat pipe at the bottom of a brine pool to form a circulation path. Said method is to convert high magnesium brine into saturated brine with a Mg2+:Na+ mass ratio between (8˜15):1 by a brine blending operation at a temperature of 60° C.˜90° C. it is controlled to be cooled and crystallized at a cooling rate of 0.6˜2.0° C./min, solid-liquid centrifugal separation is carried out when it is cooled down to 40˜48.5° C., and the solid phase is dried at a temperature of 48.5˜70° C., and finally micron-sized crystalline magnesium sulfate hollow tubes are obtained.
