Product Description
Process flow is following: sodium tungstate solution---double or tri-effect countcurrent falling film evaporator---cooling crystallization---centrifugal separation---sodium tungstate crystal the sodium tungstate solution is normally weak acid,the material of device must choose stealess steel 316L. Falling film evaporator is widely used to concentrate solutions, especially with heat sensitive components, in pharmaceutical, food, chemical and light industrial, and so on. It features high evaporative capacity, energy saving and low operating cost. What is more, materials, while being evaporated, are of invariance.
