The invention discloses a
furan distillation and purification device for
tetrahydrofuran raw materials, which comprises a
distillation box, a preheating channel, a distillate flow guide
assembly and a multi-stage filter
assembly, and the multi-stage filter
assembly comprises a first
ultrafiltration membrane treatment mechanism, a second
ion exchange resin treatment mechanism and a third
molecular sieve treatment mechanism. The upper part of the feeding end of the
distillation box is connected with a preheating channel, and inner inclined plates are arranged at the bottom of the distillation box and below the preheating channel. According to the
furan distillation and purification device for the
tetrahydrofuran raw material, when an existing
furan distillation and purification device is used for treating a furan solution, although part of impurities can be removed, the purification effect is not thorough, and
impurity residues still exist; meanwhile, the device is high in
energy consumption in the distillation and extraction process and needs to depend on the
combined use of a plurality of devices, so that the operation complexity is increased, the large loss is caused in the material conveying process, and the overall purification efficiency and the product quality are influenced.
