|
Lithium hydroxide single-effect evaporation crystallization system Introduction Single-effect evaporation is a kind of evaporation operation. It is characteriazd in that the generated secondary steam is not used for future evaporation of materials, but evaporation of a single device. For single-effect evaporation, it is usually necessary to calculate water evaporation, heating steaming consumption and heat transfer area of evaporator after given prodution tasks and determined operating conditions.
Lithium hydroxide is an inorganic substance, thechemical formul is LiOH. It is white monoclinic fine crystal, spicy, strongly alkaline and corrosive. The Ph of 1mol/L solution is about 14, and the PKB is -0.04, It can absorb carbon dioxide and water in the air ,soluble in water, slightly soluble in ethanol and insoluble in ether, The relative density is 1.45, the melting point is 471℃, and it decomposes at 925℃.
Performance Comparison for Different Evaporator
Evaporator: The liquid material inside the evaporator heated by steam for evaporation. Choose different type evaporator according to different liquid material features. Separator(crystallizer): use to separate vapor and liquid, according to different liquid features choose different type separator(crystallizer), such as normal separator, gravity separator, special design separator (crystallizer ). Vacuum system: Use to keep the whole system vacuum degree, pump some air, fixed gas, liquid entrainment of gas from the evaporator, so as to obtain the whole system stable evaporation process. Pump: Use to transfer liquid and concentrated liquid. According to different liquid features choose different pumps, such as centrifugal pump, displacement pump,screw pump. Control system: MVR Evaporation system control center, by regular motor speed, control valve,flow meter, temperature and pressure, to realize automatic evaporation, cleaning, stop operations and so on. Automatic alarm, automatic protection system is not damaged, keep dynamic balance. Cleaning system: Different liquid after period of evaporator, there maybe scaling phenomenon, general speaking, 99% of the scale can be removed by adding chemical solvent, and can use CIP clean in situ or disassemble to clean. Scope of application: Mechanical vapor compression(MVR) evaporator, suitable for milk, glucose, organic acid, VC, xylose, pharmaceutical, chemical and biological engineering, environmental engineering, waste recycling, paper making, salt industry for low temperature concentration.
