Glycerin MVR evaporation and concentration technology

A glycerin MVR evaporation and concentration technology adopts an MVR concentration evaporator, comprises steps of pre-concentration, acid-alkali treatment, concentration and evaporation, vacuum rectification, and discoloring and packaging, and is capable of producing a finished product of glycerin. The MVR concentration evaporator can generate secondary steam, through pressurization, the quality of secondary steam is improved, the potential heat of steam is fully exerted, thus the energy saving technology is realized, and the energy consumption during the glycerin concentration process is reduced.
