Description

A kind of energy-saving reverse answers dewater unit
[technical field]
The utility model relates to a kind of reaction dewater unit.
[background technology]
Often have water to generate 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 by the azeotropic distillation of ternary system and the step that reclaims entrainer to reaction raw materials, and 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 lower 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.In prior art, inorganic infiltrating and vaporizing membrane dehydration technique is mainly used in the dehydration of aqueous solvent, and such as patent CN201210442399.X discloses a kind of normal propyl alcohol process for refining, adopts inorganic infiltration evaporation membrane separation technique to carry out organics dehydration to specific products.In addition, patent CN201420287597.4 discloses a kind of reaction dewater unit, this reaction dewater unit can continue to carry out while realization response process and dehydration, but inorganic vaporization film is connected with reaction unit in reaction unit outside in this device, also be connected to Organic Ingredients condenser, the later raw material of condensation is got back in reaction unit and is continued to need again to heat when participating in reaction, causes thermal energy consumption in course of reaction relatively high.
[summary of the invention]
The purpose of this utility model is for the deficiencies in the prior art, a kind of energy-saving reverse is provided to answer dewater unit, course of reaction and dehydration are carried out in same reaction vessel simultaneously, dehydration adopts inorganic infiltration evaporation membrane technology, carry out in reaction the water sloughing generation in process in time, promote that reaction forward is carried out, Reaction time shorten, improve the yield of reaction, reduce equipment cost and energy ezpenditure.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, infiltration water condenser.Wherein reaction unit is with heater, and membrane module is inorganic infiltrating and vaporizing membrane, is fixed on reaction unit inside, is connected with the infiltration water condenser of reaction unit outside, and the infiltration water condenser other end is connected with vacuum equipment.
The method that described membrane module is fixed is: directly fix or be fixed on reaction unit sidewall or upper end cover by support.
Further preferably, described fixed form be by removably connect or non-dismountable connection mode directly or utilize support to be fixedly mounted on reaction unit sidewall or upper end cover, more preferably, removably connect can be threaded, sell, chain etc., non-dismountable connection can be welding, riveted joint etc.
By charge door, the raw material needed for reaction is joined in reaction unit, reaction unit is heated, material in reaction unit reaches boiling point vaporization, moisture is wherein isolated 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 material sloughing water continues to participate in reaction, whole system continuous service in reaction unit.
Compared with prior art, the utility model has the following advantages:
1, in existing dehydration reactor, the Gaseous materials being divested water, by the effect of Organic Ingredients condenser, is cooled to liquid state, is back in reactor, forms circulation.If do not have Organic Ingredients condenser, the two ends active force of membranous system is identical, and material cannot form circulation, and dehydration can not continue to carry out.And in the utility model, membranous system being installed to reaction unit inside, Gaseous materials and liquid material form Inner eycle in still, and material does not need the condensation cycle effect through external condenser, and dehydration can be made to continue to carry out in still.It further reduces the link that raw material heats again by getting back to reactor after Organic Ingredients condenser, greatly reducing thermal energy consumption, shortening the reaction time simultaneously, improve production efficiency.
2, the utility model is compared with existing reaction dewater unit, eliminates Organic Ingredients condenser portion, not only reduces thermal energy consumption, also reduce equipment cost.
3, the dewater unit that the utility model adopts adopts 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.

Wherein A-raw material adds entrance, and B-raw material adds entrance, 1-reaction unit, 2-heater, 3-membrane module, 4-infiltration water condenser.
[detailed description of the invention]
The utility model is further described below in conjunction with concrete operating procedure:
Load onto support at the sidewall of reaction unit 1, the mode that membrane module 3 is threaded connection is fixed on support.During concrete operations, 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 raw material, in reaction unit 1, azeotropic mixture contacts with 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 4, obtains cooling and reclaims.The Organic Ingredients removing water continues to participate in reaction in reaction unit 1.After reacting completely after testing, release product by the valve of reaction unit 1.
