Abstract

The invention provides organic solvent dehydration equipment of a pervaporation membrane. The equipment comprises a feedstock pump, a preheater, an evaporator, a tail pump, a gas-liquid separator, a superheater, a dehydration device, a penetrating fluid receiving tank, a vacuum unit, a finished product condenser and a finished product tank. According to the equipment, as a dehydration system of a comprehensive membrane is adopted, the quality requirements which cannot be achieved by the traditional method are overcome, and the comprehensive utilization benefit is improved; the tail pump can be used for continuously and quantitatively discharge pollution; the gas-liquid separator can achieve the reduction of entrainment of the evaporator; the heat loss of airflow is compensated by the superheater, so that the temperature of feedstock is guaranteed; the preheater can achieve the reduction of energy consumption by utilizing heat exchange between product steam and feedstock; a membrane component adopts a jacket structure, so that materials are prevented from being liquefied; the feedstock is provided with an online monitor, so that the physical property of a membrane feeding material is ensured to be qualified; produced penetrating fluid is recycled to a distillation column again, and residues are recycled, so that energy is saved, emission is reduced, and the equipment is beneficial to environmental protection.

Description

technical field [0001] The invention relates to the field of medicine and chemical industry, in particular to a pervaporation membrane organic solvent dehydration device. Background technique [0002] In the process of traditional organic solvent dehydration recovery, since it azeotropes with water during rectification, the water cannot be fully removed, and the recovery and recycling effect cannot be achieved. Contents of the invention [0003] In order to overcome the above defects and meet the requirements of comprehensive recycling, the present invention provides a pervaporation membrane organic solvent dehydration device. [0004] The technical scheme that the present invention adopts is as follows: [0005] A pervaporation membrane organic solvent dehydration equipment, including raw material pump, preheater, evaporator, raffinate pump, gas-liquid separator, superheater, dehydration device, permeate receiving tank, vacuum unit, finished product condenser, finished p...
