Description
Technical field
The utility model belongs to technical field of chemical, and in particular to a kind of plasticizer esterification device.
Background technology
Plasticiser, or plasticizer, plasticizer are a kind of flexibilities for increasing material or make the liquefied additive of material.
It adds object and contains plastic cement, concrete, wall material, cement and gypsum etc..Same plasticiser is frequently used in not
With object on, but its effect often and differs.Up to over one hundred kind of plasticiser species, but the use of obtain most common is a group
The referred to as compound of phthalate.Global plasticiser market in 2004 according to statistics, total amount is about at 5,500,000 tons or so
And strided forward towards 6,000,000 tons.
It is well known that in esterification, temperature is higher, and esterification reaction rate is faster, traditional esterification column, the alcohol of high-temperature
Gas is rapidly entered in esterification column, and esterification quality cannot be guaranteed, and esterification rate is low, to obtain the product of high quality
Esterification reaction process can only be increased, energy consumption is big, and being not suitable for new era energy-saving and environment-friendly form needs.
Utility model content
The purpose of the utility model is to overcome the deficiencies in the prior art, there is provided a kind of simple in structure, reaction efficiency and quality
High plasticizer esterification device.
The technical solution of the utility model is as follows：A kind of plasticizer esterification device, including be sequentially connected esterifying kettle,
Esterification column, alcohol water condenser, esterification phase separation tank, are also associated with secondary plus alcohol tank on the esterification column, the top of esterifying kettle and
Bottom is respectively arranged with inlet port and outlet port.
Further, the inside and outside of the esterifying kettle is respectively arranged with inner coil pipe and outer coil pipe, is gone back in esterifying kettle
It is provided with agitating device.
Further, the alcohol water condenser is also associated with exhaust collection tank.
Further, the esterification phase separation tank is two groups, two groups of esterification phase separation tank series connection.
Further, it is additionally provided with U-tube between the esterification phase separation tank and esterification column.
Further, esterification phase separation tank is also associated with alcohol water collecting tank.
The operation principle of the utility model is：Raw material is added in esterifying kettle by feed inlet, esterifying kettle inner coil pipe and external disk
Pipe heats raw material, and agitating device is stirred raw material, and esterification generation water vapour and gaseous alcohol occur for raw material
And entering esterification column, esterification generation water vapour and gaseous alcohol are up to 180 DEG C or so.Water vapour and gaseous alcohol are being esterified
After alcohol, the alcohol of esterification column overhead reflux entered in tower with secondary plus alcohol tank contacts so that the temperature in esterification column is slowly lifted,
The speed and quality of esterification are effectively protected.It is cold after alcohol water after esterification cools into alcohol water condenser
Condensate enters alcohol water collecting tank, and tail gas enters exhaust collection tank, and the alcohol water to cool enters esterification phase separation tank and carries out esterification point
Phase, alcohol phase enter esterification column through U-tube.After confirmation to be esterified is qualified, using the waste heat in esterifying kettle, by the part in esterifying kettle
Alcohol excess is steamed from esterifying kettle, the mixture of esterifying kettle lactonization reaction generation after discharge port is handled into filter progress,
Up to plasticizer product.
The utility model is beneficial in that, secondary plus alcohol tank is added on esterification column so that the temperature in esterification column
Slowly lifting, the speed and quality of esterification are effectively protected, and reduce esterification cyclic process, reduce energy consumption, improve
Production efficiency.
