Description

Trioctyl trimellitate production equipment
Technical field
The utility model relates to a kind of plasticizer production device, is specifically related to a kind of trioctyl trimellitate production equipment.
Background technology
The throughput of traditional trioctyl trimellitate is little, and the reactor of general esterification step is 2, esterification column number of units is 2.In just conventional production method:
(1) yield in unit time is low,
(2) energy consumption is large,
(3) plant factor is low,
(4) product yield is low,
(5) unstable product quality.
Trioctyl trimellitate production equipment, esterifier 2, esterification column has 2.Pure product is obtained by neutralization &washing, stripping, filter progress successively after esterification.
Utility model content
According to above deficiency of the prior art, the technical problems to be solved in the utility model is: provide a kind of trioctyl trimellitate production equipment, less investment, reduce energy consumption, improve yield, improve plant factor, improve the quality of products.
The utility model solves the technical scheme that its technical problem adopts:
Trioctyl trimellitate production equipment described in the utility model, comprise esterifying kettle, esterifying kettle, the first strainer, stripping vessel, decolouring still are connected successively with the second strainer, esterifying kettle, esterification column, condenser are connected successively with the first separating tank, esterification column is connected with the first separating tank, and stripping vessel, stripping tower, interchanger are connected successively with vacuum pump.
Described interchanger is connected with the second separating tank.
Principle of work and process:
Inclined for raw material acid anhydride, octanol and organotin catalysts are added in esterifying kettle, under the condition of heating, in esterifying kettle, the alcohol of water generation reaction and evaporation enters esterification column after leaving esterifying kettle, enter condenser after the alcohol and water steam that esterifying kettle evaporates in esterification column contacts with the recycle alcohol of trim the top of column is reverse to cool, enter the first separating tank more settlement separate, alcohol enters esterification column tower top mutually and contacts with water generation reaction steam is reverse with the alcohol steam produced in reaction process, and the alcohol after refining enters esterifying kettle and uses as backflow alcohol.In esterifying kettle, reacted mixture is through the first strainer by catalyst recovery, and mixture enters in stripping vessel, first in stripping vessel, carries out neutralization &washing, to reduce product acid number; Then under the effect of vacuum pump, make stripping vessel form negative pressure, under negative pressure state, by the alcohol and water detachment system in mixture, alcohol and water to enter in interchanger after condensing cooling cooling through stripping tower, enters the second separating tank.In stripping vessel, leftover materials are thick product, are poured into by thick product in decolouring still, mixs with gac, to reduce product look number and to adsorb to fall part solid impurity in thick product.Containing the thick product of gac through the second metre filter, obtain the product of high-quality.
The beneficial effect that the utility model has is: decrease cost of investment, improves conversion rate of products, and energy consumption reduces further, constant product quality, and device operation efficiency obtains larger raising.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation;
In figure: 1, esterifying kettle; 2, the first strainer; 3, stripping vessel; 4, decolour still; 5, the second strainer; 6, esterification column; 7, condenser; 8, the first separating tank; 9, stripping tower; 10, interchanger; 11, vacuum pump; 12, the second separating tank.
Embodiment
Below in conjunction with accompanying drawing, embodiment of the present utility model is described further:
As described in Figure 1, the utility model comprises esterifying kettle 1, esterifying kettle 1, first strainer 2, stripping vessel 3, decolouring still 4 are connected successively with the second strainer 5, esterifying kettle 1, esterification column 6, condenser 7 are connected successively with the first separating tank 8, esterification column 6 is connected with the first separating tank 8, and stripping vessel 3, stripping tower 9, interchanger 10 are connected successively with vacuum pump 11.
Interchanger 10 is connected with the second separating tank 12.
Inclined for raw material acid anhydride, octanol and organotin catalysts are added in esterifying kettle 1, under the condition of heating, in esterifying kettle 1, the alcohol of water generation reaction and evaporation enters esterification column 6 after leaving esterifying kettle 1, enter condenser 7 after the alcohol and water steam that esterifying kettle 1 evaporates in esterification column 6 contacts with the recycle alcohol of trim the top of column is reverse to cool, enter the first separating tank 8 more settlement separate, alcohol enters esterification column 6 tower top mutually and contacts with water generation reaction steam is reverse with the alcohol steam produced in reaction process, and the alcohol after refining enters esterifying kettle 1 and uses as backflow alcohol.In esterifying kettle 1, reacted mixture is through the first strainer 2 by catalyst recovery, and mixture enters in stripping vessel 3, first in stripping vessel 3, carries out neutralization &washing, to reduce product acid number; Then under the effect of vacuum pump 11, make stripping vessel 3 form negative pressure, under negative pressure state, by the alcohol and water detachment system in mixture, alcohol and water to enter in interchanger 10 after condensing cooling cooling through stripping tower 9, enters the second separating tank 12.In stripping vessel 3, leftover materials are thick product, are poured into by thick product in decolouring still 4, mixs with gac, to reduce product look number and to adsorb to fall part solid impurity in thick product.Thick product containing gac filters through the second strainer 5, obtains the product of high-quality.
