Sodium fluoride dryer
Sodium fluoride is generally selected drying system vibration fluidized bed or spin flash dryer, strengthening the airflow drying machine (also known as the efficient air drier), system configuration and equipment structure to adapt to the material drying characteristics is the key to ensure the continuous and stable operation of plant, plant should configure corresponding online detection system, so that the operator control and analysis.
Properties of sodium fluoride: colorless free-flowing cubic or tetragonal crystals. The density of 2.558 g/cm3. Melting point is 993 ℃. The boiling point of 1695 ℃. Soluble in water. The aqueous solution is alkaline. Corrode glass. Slightly soluble in alcohol. It dissolves in hydrofluoric acid to form sodium hydrogen fluoride. Poisonous! LD50180 ~ 250 mg/kg. It is an inorganic fluoride insecticide.
In the configuration of sodium fluoride drying system, according to the physical conditions, appropriate improvements should be made in terms of improving thermal efficiency, energy saving, etc., so that the equipment can run continuously and stably, and the fluctuation of drying index caused by system fluctuations can be avoided. It is an important guarantee for the stable operation of the system that the device is equipped with targeted online indicator detection, so that the operator can monitor the system in real time and find the cause of the system working condition fluctuation in time for correction.
