Abstract
The utility model provides a kind of reaction dewater unit, and this device is made up of reaction unit, membrane module, Organic Ingredients condenser, infiltration water condenser.Wherein reaction unit is with heater, and membrane module is inorganic infiltrating and vaporizing membrane, is connected with water condenser, and water condenser one end is connected with vacuum equipment.This device has promotion reaction to carry out to positive direction, and enhance productivity, technical process is simple, and safety coefficient is high, compact conformation, small investment, energy-efficient feature.
Description
[technical field]
The utility model relates to a kind of reaction dewater unit.
[background technology]
Often have the generation of water in organic synthesis, such as in esterification, etherification reaction, condensation reaction, prepare acid anhydrides, prepare the generation having water in the reaction of acid amides.The water generated suppresses the carrying out of reaction, must remove as early as possible.Dehydration technique is in the past reactive distillation, azeotropic distillation, extracting rectifying mainly, and so not only energy consumption is high, and easily forms secondary pollution.Such as patent CN201320552322.8 discloses a kind of ring-closure reaction dewater unit, comprise reactor, condenser, gas-liquid separator and measuring tank, this device is primarily of gas-liquid separator separates water outlet and organic solvent, reaction forward is kept to carry out, its dehydration is dewatered to the step of reaction raw materials by the azeotropic distillation of ternary system and recovery entrainer, this device has that energy consumption is high, cost is high, to shortcomings such as environment and product pollute.
Inorganic infiltration evaporation membrane technology can realize the separation task that the conventional methods such as distillation, extraction, absorption have been difficult to low energy consumption, realize the separation requirement that conventional method is difficult to maybe cannot realize, have broad application prospects.It is simple that the method has technical process, and safety coefficient is high, compact conformation, small investment, energy-efficient feature.But traditional inorganic infiltrating and vaporizing membrane dehydration technique is mainly used in the dehydration of aqueous solvent, and infiltration evaporation membrane technology and reaction unit are designed to the system of two isolated operations respectively, such as patent CN201210442399.X discloses a kind of normal propyl alcohol process for refining, inorganic infiltration evaporation membrane separation technique is adopted to carry out organics dehydration to specific products, although this technology can replace distillation, extraction, the traditional separation methods such as absorption, in organic matter or mixing organic matter, removing of moisture has obvious advantage, but the carrying out that can not continue while realization response process and dehydration.
[summary of the invention]
The purpose of this utility model is for the deficiencies in the prior art, a kind of reaction dewater unit is provided, course of reaction and dehydration are carried out simultaneously, dehydration adopts inorganic infiltration evaporation membrane technology, reacting the water sloughing generation in the process of carrying out in time, promote that reaction forward is carried out, fast reaction speed, improve the yield of reaction.This device can be applied to allly to be had water to generate and needs in the reaction that removes, such as esterification, etherification reaction, condensation reaction, prepares the dehydration of acid anhydrides, prepares the dehydration of acid amides.
The technical solution of the utility model is: a kind of reaction dewater unit, is characterized in that being made up of reaction unit, membrane module, Organic Ingredients condenser, infiltration water condenser.Wherein reaction unit is with heater, and membrane module is inorganic infiltrating and vaporizing membrane, is connected with water condenser, and water condenser one end is connected with vacuum equipment.
Described reaction unit is connected with membrane module, and membrane module is connected with Organic Ingredients condenser, infiltration water condenser respectively, and Organic Ingredients condenser is connected with reaction unit.
Join in reaction unit by charge door by the raw material needed for reaction, heat reaction unit, the vaporization of material in reaction unit, by membrane module, is isolated moisture wherein by inorganic infiltrating and vaporizing membrane.Infiltration water is subject to the effect of vacuum equipment, is reclaimed by the condensation of infiltration water condenser.The Organic Ingredients sloughing water is got back in reaction unit by the condensation of Organic Ingredients condenser, continues to participate in reaction, whole system continuous service.
Compared with prior art, the utility model has the following advantages:
1, the utility model adopts the successive reaction dewater unit that reaction unit and dewater unit are integrated, and course of reaction and dehydration can be made to carry out simultaneously, promotes that reaction is carried out to positive direction, improves production efficiency.
2, the dewater unit that the utility model adopts is inorganic infiltration evaporation membrane technology, and it is simple that this technology has technical process, and safety coefficient is high, compact conformation, small investment, energy-efficient feature, avoids the secondary pollution in traditional handicraft.
[accompanying drawing explanation]
Fig. 1 is reaction dewater unit schematic diagram
Wherein A-raw material adds entrance, and B-raw material adds entrance, 1-reaction unit, 2-heater, 3-membrane module, 4-Organic Ingredients condenser, 5-infiltration water condenser; Reaction unit is connected with membrane module, and membrane module is connected with Organic Ingredients condenser, infiltration water condenser respectively, and Organic Ingredients condenser is connected with reaction unit.
[detailed description of the invention]
The utility model is further described below in conjunction with concrete operating procedure:
First, add required reaction raw materials by charge door A and B, open the mixing plant of reaction unit 1, open the heater 2 of reaction unit 1, the raw material in reaction unit 1 is heated up.When temperature reaches the boiling point of reaction unit Raw, in reaction unit 1, azeotropic mixture can pass through membrane module 3, the water that reaction generates can be separated by the effect of infiltration vaporization membrane module, isolated water under the effect of removing vacuum equipment, by infiltration water condenser 5, can obtain cooling and reclaims.The Organic Ingredients removing water by the condensation of Organic Ingredients condenser 4, can turn back in reaction unit 1 and continues to participate in reaction.After reacting completely after testing, release product by the valve of reaction unit 1.
