Abstract
The utility model relates to a reflux condenser for esterification reaction, belonging to the technical field of chemical mechanical equipment. The utility model designs the reflux condenser in an optimal structure. the condenser is divided into several sections which are partitioned by tube plates, and cooling water flows from the top section to the bottom section step by step, so that the temperature of the condenser can be reduced from low to high. In the design, the rule that in the conventional condenser, the cooling water flows into from the lower to the upper to form the lower low-temperature section and the upper high-temperature section is changed; after section division, the cooling water at lower temperature flows into from the bottom of the upper section, flows out from the top of the upper section, flows into from the bottom of the middle section, flows out from the top of the middle section, flows into the bottom of the lower section and is finally discharged from the top of the lower section; the temperature of the cooling water at the upper section is minimum; and the temperature of the cooling water at the lower section is maximum, so that condensation areas the temperature of which is gradually increased from top down can be formed; and the condenser in the structure has condensation and steaming functions. During the condensation process, the separation of light and heavy components can be completed; and the reflux condenser has the effects of energy saving, consumption reduction, pollution emission reduction and the like.
Description
Technical field
A kind of esterification is used reflux condenser, and the utility model is to the improvement of the reflux condenser of routine use, belongs to the chemical mechanical equipment technical field.
Background technology
Esterification is an acid and alcohol reaction generation ester and water, and reaction equation is following:
Esterification is reversible reaction, has only the W (water) that constantly will react generation to remove, and reaction just possibly carried out to the esterification direction, and production procedure is as shown in Figure 4.
In this process; Reflux condenser plays crucial effects, and particularly boiling point is greater than 100 ℃ raw alcohol and acid, and reflux condenser is equivalent to one and steams condenser; Let raw alcohol and acid condensation in this condenser get back to agitated reactor on the one hand; On the other hand, let water generation reaction constantly discharge, make reaction proceed to terminal point.
Conventional now reflux condenser structure is as shown in Figure 3: the mixed vapour that agitated reactor steams gets into condenser from bottom (head); In condenser; The acid and the pure condensation that are higher than 100 ℃ of boiling points are returned into agitated reactor; Control out condenser steam greater than 100 ℃, water can vapor form be discharged condensation in second condenser.
Conventional condenser is because the rule that goes out on advancing under the chuck cooling water; Forming condenser is low-temperature zone; Top improve to form high temperature section because of water outlet temperature, and desirable reflux condensation mode process should to be the bottom go progressively condensation to get off on the way, stay remaining water vapour discharge basically to the top.And the condensation process of the cold top heat in the present this end, let water in the bottom a large amount of condensations return in the still, the influence reaction is carried out.For discharge water as early as possible, must strengthen the heating load of still, such consequence has two: 1. a part of water is gone into agitated reactor at the very fast condensing reflux of condenser low-temperature space; For this part water is steamed; Agitated reactor must strengthen heating demand, this part water is steamed to being enough to, like this; The circulation repeatedly of considerable part water experience condensation-vaporization-condensation-vaporization is arranged at the agitated reactor top, loss many energy; 2. because the assurance water vapour can be discharged from condenser overhead, and necessary heating load improves medium temperature in the condenser, will certainly take a part of raw alcohol and acid out of like this, this has just increased the load of the consumption of raw materials and the three wastes.
Summary of the invention
The purpose of the utility model is to overcome above-mentioned difficulties, provides a kind of esterification of each condensation segment that temperature from top to down increases progressively that comprises to use reflux condenser.
The technical scheme of the utility model: a kind of esterification is used reflux condenser, comprises steam inlet 1, steam (vapor) outlet 2, cooling water inlet 3, coolant outlet 4; The jet chimney that esterification generates is located on the reflux condenser axis, and said esterification also comprises shell 9 and bobbin carriage 10 with reflux condenser, and bobbin carriage 10 is divided into the 3-6 section; To be divided into 3 sections is that example is explained as follows: epimere 5 is the cooling water low-temperature space, and stage casing 6 is a warm area in the cooling water, and hypomere 7 is the cooling water high-temperature region; Every section all is provided with water inlet in the section following side; Upper lateral part is provided with delivery port, and the water inlet of epimere 5 promptly is a cooling water inlet 3, and the delivery port of epimere 5 is connected with the water inlet in stage casing 6; The delivery port in stage casing 6 is connected with the water inlet of hypomere 7, and the delivery port of hypomere 7 promptly is a coolant outlet 4; Every section shell 9 is corresponding with every section bobbin carriage 10;
Said bobbin carriage 10 is divided into the 3-6 section, installs a concentric tube sheet 8 between per two sections additional, bobbin carriage 10 every section isolate through concentric tube sheet 8, bobbin carriage 10 upper ends and lower end are equally through end socket 11 and seal washer 12 fixing and sealings.
Said every section shell 9 adopts " Hough " to piecing together, and be connected with tube sheet with joining the brill flange, or the Hough shell directly welds again.
The utility model is divided into multistage with condenser, and for example three sections, the cooling water that temperature is lower advances from the epimere bottom; Advance from the bottom, stage casing again after coming out from the epimere top, come out to get into the hypomere bottom from the top, stage casing, discharge from the hypomere top at last; Minimum at the epimere coolant water temperature, the hypomere coolant water temperature is the highest, can form each condensing zone that temperature from top to down increases progressively like this; The reactor mixed vapour gets into the high boiling raw alcohol in high-temperature region, bottom, the acid vapor condensation is returned in the still; To the stage casing, because epimere low-temperature space part water vapour is condensed into water, the higher boiling raw material steam of not accomplishing condensation with fraction contacts; Produce the heat exchange of gas-liquid phase, the condensation of higher boiling steam is with the lower boiling water of heat transferred.This part water is evaporated again, and eductor condenser, the condenser of this structure has condensation-steam function.
To the syllogic condenser, have four concentric circles tube sheets, in order to guarantee that tube sheet can adopt the technology of joining brill with one heart; After each tube sheet welding, make simple annealing in process, in order to avoid pipe has bigger distortion; Influence concentricity, shell is divided into three joints, fixes with tube sheet and is connected through flange and sealing gasket.
The beneficial effect of the utility model: the utlity model has condensation-steam function, in condensation process, accomplish the separation of light-heavy component, have energy-conservation, reduce effects such as consuming, reduce disposal of pollutants.
