Abstract
The invention discloses a kind of Intubaction devices for butyl acetate reaction kettle, intubation is connected on reaction kettle by flange pup joint, inside there is the tubule of two plus sulfuric acid and water, the present apparatus can in time bring out butyl ester from reaction kettle, promote reaction to carry out to positive direction, is conducive to improve positive reaction speed, while improving reaction kettle load, the respond for accelerating reaction kettle, helps to propose production.
Description
Technical field
The present invention relates to chemical equipment technical field, more particularly to a kind of inserting for butyl acetate reaction kettle
Pipe device.
Background technique
Currently, the esterification production process of acetate is typically all to first pass through the preheating of reboiler, then entered by intubation
Material is set to react into esterifying kettle, then through the high-temperature heating in esterifying kettle, reaction product and a small amount of material gasification
Entered in esterification column by riser via trap afterwards and separated, to complete preliminary esterification separation.
When the ester and water produced after butyl ester reaction forms azeotropic mixture, water shortage, in order to accelerate product acetic acid fourth
Ester is taken away, and now determines to add recovery process water 100-150L/h (80 DEG C of temperature) inside butyl ester reaction kettle, in time takes butyl ester out of
Come, reaction is promoted to carry out to positive direction, is conducive to improve positive reaction speed, while improving reaction kettle load, accelerates reaction kettle
Respond, help to propose production.
The concentrated sulfuric acid is usually 10-15 days plus 80 kilograms, is changed to continuously be added dropwise now, avoids moment punching when conventional plus sulfuric acid
The increase of side reaction caused by load is hit, while reaction kettle sulfuric acid can be maintained in a metastable amount, is conducive to stable reaction
It carries out.
Therefore, the present invention provides a kind of Intubaction devices, can be used for butyl acetate reaction kettle.
Summary of the invention
In view of this, can promote anti-the object of the present invention is to provide a kind of Intubaction device with butyl acetate reaction kettle
It should be carried out to positive direction, be conducive to improve positive reaction speed, while improving reaction kettle load, accelerate the reaction energy of reaction kettle
Power helps to propose production.
In order to achieve the above object, the present invention adopts the following technical scheme:
A kind of Intubaction device for butyl acetate reaction kettle, including reaction kettle, flange pup joint, intubation；
The Intubaction device is installed on the top of reaction kettle by the flange pup joint；
The intubation is connected with the flange pup joint, and the intubation uses barrel forms, including outer tube, sulfuric acid feed pipe
And water inlet pipe, the sulfuric acid feed pipe are set to the inside of the outer tube with the water inlet pipe；The outer tube and sulfuric acid are fed
Abacus is fixed between pipe and water inlet pipe.
The present invention passes through inner tube (sulfuric acid feed pipe, water inlet pipe) to esterifying kettle (reaction kettle) enriching sulfuric acid and Jia Shui, with ester
Change the material hybrid reaction in kettle, the material and gas after heating in esterifying kettle enter riser by outer tube, enter back into esterification
Tower.
Preferably, the intubation is made of zirconium material.
Preferably, the flange pup joint is made of zirconium material or stainless steel.
Preferably, the intubation is deep into reactor bottom
Further, the Intubaction device is mounted at the preformed hole of reaction kettle kettle top.
It can be seen via above technical scheme that compared with prior art, the present invention has the beneficial effect that:
1, the present invention effectively takes butyl acetate out of, and reaction is promoted to carry out to positive direction, is conducive to improve positive reaction speed.
2, the present invention improves reaction kettle load simultaneously, accelerates the respond of reaction kettle, helps to propose production.
3, the configuration of the present invention is simple, it is only necessary to be installed at esterifying kettle preformed hole by flanged joint.
4, integral device materials'use of the present invention is few, and is directly installed on esterifying kettle kettle top, without carrying out big transformation, even
Continuous metaplasia produces the maintenance cost and cost of labor for effectively reducing recycling, has broad application prospects.
