Electric dehydrating device for acetone

Abstract

The invention discloses an electric dehydrating device for acetone. The electric dehydrating device comprises a sealing device, wherein a dicyan acetone aqueous solution feeding tube is mounted in the sealing device; the top of the dicyan acetone aqueous solution feeding tube is fixed on the top surface in the sealing device; the bottom of the dicyan acetone aqueous solution feeding tube penetrates through the sealing device and is communicated with a dehydrating tube; a permeation vaporization film separator is mounted on the dehydrating tube; the permeation vaporization film separator is fixed on the dehydrating tube; the bottom of the dehydrating tube is communicated with an evaporator; the evaporator is connected with the dehydrating tube through an internal pipeline; a vacuum device is mounted on the side surface of the evaporator; the vacuum device and the evaporator are connected through a vacuum tube; a crystalline liquid storage device is arranged on the upper surface of the vacuum device. The electric dehydrating device for acetone is simple in process, high in safety coefficient, less in equipment investment, high in energy utilization rate and small in floor space in the whole process, the dehydration and concentration temperature is reduced, the decomposition loss of dihydroxy acetone is reduced, and the separating efficiency of a dihydroxy acetone product is improved.

Description

technical field [0001] The invention relates to a dehydration device, in particular to an acetone electric dehydration device. Background technique [0002] Acetone is a five-color volatile and flammable liquid with a slight aroma. It can be dissolved in water, ethanol, ether and other organic solvents. Acetone is an important raw material for organic synthesis and is used in the production of epoxy resin, polycarbonate, plexiglass, and pharmaceuticals. It is also a good solvent for coatings, adhesives, acetylene in steel cylinders, etc. It can also be used as a diluent, cleaning agent and extractant. Since the dihydroxyacetone reaction solution is generally a dihydroxyacetone aqueous solution with a lower concentration after preliminary separation and purification, in order to obtain a high-purity dihydroxyacetone solid powder, the water in the dihydroxyacetone must be removed by simple distillation. This method not only cannot effectively remove moisture, but also easily ...

Since the dihydroxyacetone reaction solution is generally a dihydroxyacetone aqueous solution with a lower concentration after preliminary separation and purification, in order to obtain a high-purity dihydroxyacetone solid powder, the water in the dihydroxyacetone must be removed by simple distillation. The method not only cannot effectively remove moisture, but also easily causes the decomposition loss of the product
