Abstract
The utility model discloses a kind of esterification reaction tower, be provided with reactor (1), esterification column and steam pipe (4), described reactor (1) top is provided with charging aperture (2) and exhaust outlet (3), and bottom is provided with discharging opening (6); Described steam pipe (4) is provided with and is installed on the steam inlet (5) of answering still top, and described steam pipe (4) is through reactor (1) bottom, and described steam pipe is provided with equally distributed steam hole through reactor bottom part.It is bad that the utility model has solved existing firing equipment heating effect, effectively improved the efficiency of heating surface, and esterification balance is moved to positive reaction direction.
Description
Technical field
The utility model relates to chemical reaction device, particularly a kind of esterification reaction tower.
Background technology
Ethyl acetate esterification is that to take acetic acid and ethanol be raw material, and sulfuric acid is that catalyst for making direct esterification obtains ethyl acetate, and esterification must just can be carried out at a certain temperature.And esterification is reversible reaction, by heating, it is moved to positive reaction direction, improve the reaction efficiency of raw material, promote the generation of ethyl acetate.
But current heater heating effect is poor, can not reach the effectively fully object of heating reactant, the carrying out of impact reaction be output and the quality of product even.
Summary of the invention
The utility model object is to overcome the deficiencies in the prior art, and a kind of esterification reaction tower is provided, and by steam, evenly fully adds thermal reaction mixture, improves reaction rate, and balance is moved to positive direction, improves the conversion ratio of raw material.
To achieve these goals, the technical scheme that the utility model patent adopts:
An esterification reaction tower, is provided with reactor, esterification column and steam pipe, and described reactor top is provided with charging aperture and exhaust outlet, and bottom is provided with discharging opening; Described steam pipe is provided with and is installed on the steam inlet of answering still top, and described steam pipe is through reactor bottom, and described steam pipe is provided with equally distributed steam hole through reactor bottom part.
As of the present utility model, further illustrate, its base wall of described steam pipe is partly provided with equally distributed steam hole, and the vertical steam pipe base section of steam pipe is provided with equally distributed steam hole.
As of the present utility model, further illustrate, described steam hole only allows gas to pass through.
As of the present utility model, further illustrate, in described steam hole, be provided with air filter film, its pore size is 100 ~ 200 orders.
Operation principle of the present utility model: add reaction raw materials respectively from charging aperture, after adding raw material, toward steam inlet, add steam, steam is by steam vent heating raw mixture, by steam, from emerging of steam hole, can reach the effect of stirring, mixture is fully mixed, the carrying out that promotes reaction, the waste gas of reactor is discharged processing by exhaust outlet; The reactant obtaining after reacting completely enters esterification column by discharging opening, by rectifying, separation, obtains ethyl acetate.
The beneficial effects of the utility model: solved existing firing equipment heating effect bad, effectively improved the efficiency of heating surface, esterification balance is moved to positive reaction direction.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the structural representation of the utility model embodiment 2.
In figure: 1-reactor; 2-charging aperture; 3-exhaust outlet; 4-steam pipe; 5-steam inlet; 6-discharging opening.
The specific embodiment
Below in conjunction with drawings and Examples, the utility model is further illustrated, but protection domain of the present utility model is not only confined to following examples.
Embodiment 1
An esterification reaction tower, as shown in Figure 1, is provided with reactor 1, esterification column and steam pipe 4, and described reactor 1 top is provided with charging aperture 2 and exhaust 3, and bottom is provided with discharging opening 6; Described steam pipe 4 is provided with and is installed on the steam inlet 5 of answering still top, and described steam pipe 4 is through reactor 1 bottom, and described steam pipe 4 is provided with equally distributed steam hole through reactor 1 base section, and described steam hole only allows gas to pass through.In described steam hole, be provided with air filter film, its pore size is 200 order left and right.
The present embodiment operation principle: add reaction raw materials respectively from charging aperture, after adding raw material, toward steam inlet, add steam, steam is by steam vent heating raw mixture, by steam, from emerging of steam hole, can reach the effect of stirring, mixture is fully mixed, the carrying out that promotes reaction, the waste gas of reactor is discharged processing by exhaust outlet; The reactant obtaining after reacting completely enters esterification column by discharging opening, by rectifying, separation, obtains ethyl acetate.
Embodiment 2
The present embodiment is different from embodiment 1 to be: as shown in Figure 2, the vertical steam pipe base section of described steam pipe 4 is provided with equally distributed steam hole, in described steam hole, is provided with air filter film, and its pore size is 100 order left and right, and all the other structures are identical with embodiment 1.Can more fully be uniformly mixed raw material, it is fully mixed, heat more evenly, improve reaction efficiency.
