Summary: | The invention discloses a reagent grade hydrofluoric acid preparation device. The reagent grade hydrofluoric acid preparation device comprises a drying tank; a feeding port is mounted in one side of the upper part of the drying tank; an air pump is mounted on one side, far away from the feeding port, of the upper part of the drying tank; and an air introducing pipe is mounted at an output end of the air pump. The reagent grade hydrofluoric acid preparation device is provided with the drying device; fluorite powder is subjected to complete drying treatment through hot air sprayed from a rotaryspraying head to prevent water in the undried fluorite powder from influencing the concentration of hydrofluoric acid after a production reaction, so that the production quality is improved; the hydrofluoric acid preparation device is provided with two groups of distillation columns, namely, a crude distillation column and a rectifying column; the crude distillation column is mainly used for removing most sulphuric acid, |
