The utility model relates to the technical field of
glycerol production, in particular to a desalting device for
glycerol production. Comprising a
distillation pool, a sealing cover and an auxiliary
assembly, the auxiliary
assembly comprises a feeding
pipe, a spiral roller, a filter screen, a cleaning
pipe, a cleaning valve, a discharging valve, a driving component and a discharging component, crude glycerin is conveyed into the
distillation pool through the feeding
pipe, filtered through the filter screen and then enters an upper side cavity of the
distillation pool, and the distillation pool is operated to be heated to increase the
internal temperature of the distillation pool; after glycerin in the distillation pool reaches a
boiling point and starts to evaporate, the evaporated glycerin flows out through the
discharge component and is collected into refined glycerin, a large amount of salt and other impurities which cannot be evaporated precipitate to the bottom in the distillation pool under the action of gravity, and then the
discharge valve is opened to lead out and realize cleaning, so that during glycerin production and
processing, the production efficiency is improved, and the production cost is reduced. The cleaning efficiency of desalting and other impurities can be improved, the manual cleaning intensity is relieved, the
processing efficiency is effectively improved, and the
processing yield and the yield are improved.
