Abstract
The utility model discloses a kind of distillation column reaction liquid feed back pipe, comprise rectifying column, the bottom of described rectifying column is provided with pipeline, and the other end of pipeline is provided with reactor, and the top of rectifying column is provided with feed back pipe; In described reactor, coil pipe is installed; Described feed back pipe is located at rectifier and between whole tower body 1/1 to four/6th.The utility model reduces the temperature in tower, improves the distribution ratio of methyl alcohol, reduces the upper top ratio of 2,2-dimethoxypropane.By the original time 50% adding methyl alcohol, be down to about 5%, substantially increase reaction efficiency, saved production cost.
Description
Technical field
The utility model relates to 2,2-dimethoxypropane consersion unit technical field, is more particularly a kind of distillation column reaction liquid feed back pipe.
Background technology
At present, in 2,2-dimethoxypropane reaction tower, because the feed back pipe of reactant liquor is installed lower, the number of times adding methyl alcohol in production process is frequent, makes the reaction temperature in tower higher, and cost required in production is larger.
Utility model content
The purpose of this utility model is to make up the deficiencies in the prior art, provides a kind of distillation column reaction liquid feed back pipe.
Of the present utility model, object is achieved through the following technical solutions:
A kind of distillation column reaction liquid feed back pipe, comprise rectifying column, it is characterized in that: the bottom of described rectifying column is provided with pipeline, the other end of pipeline is provided with reactor, and the top of rectifying column is provided with feed back pipe.
Described a kind of distillation column reaction liquid feed back pipe, is characterized in that: be provided with coil pipe in described reactor.
Described a kind of distillation column reaction liquid feed back pipe, is characterized in that: described feed back pipe is located at rectifier and between whole tower body 1/1 to four/6th.
The utility model has the advantage of:
The utility model reduces the temperature in tower, improves the distribution ratio of methyl alcohol, reduces the upper top ratio of 2,2-dimethoxypropane.By the original time 50% adding methyl alcohol, be down to about 5%, substantially increase reaction efficiency, saved production cost.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
