Abstract
The utility model discloses a kind of acidylate distilling apparatus of stable gas pressure, its innovative point is: comprise condenser, first-level buffer tank, level 2 buffering tank and Roots vaccum pump; First-level buffer tank is provided with entrance a and outlet a, and level 2 buffering tank is provided with entrance b and outlet b; Be connected with the entrance a of first-level buffer tank by pipeline a bottom described condenser, the outlet a of first-level buffer tank is by pipeline b and level 2 buffering tank entrance b, and level 2 buffering tank outlet b is connected with Roots vaccum pump.The utility model, by arranging two-stage surge tank, can not only effectively prevent logistics solidification and crystallization, can also reduce residual acid value, reduce sour gas directly with vavuum pump drive member contacts, effectively ensure vacuum, raising distilling effect.
Description
Technical field:
The utility model belongs to technical field of chemical, is specifically related to a kind of acidylate distilling apparatus of stable gas pressure.
Background technology:
After acylation reaction terminates, material need be evacuated to distillation still vacuum distillation, this process need uses high vacuum; higher to vacuum level requirements, but in still-process, because logistics is easy to solidification and crystallization; vacuum pipe can be caused to block, affect vacuum and distilling effect.In addition after acylation reaction; inevitably have residual acid value; sour gas can be produced in still-process; when Roots vacuum system provides vacuum source; sour gas cognition produces very large corrosion to vacuum grease and dynamic component; sour gas directly with vavuum pump drive member contacts, there will be the problems such as vacuum grease is rotten, dynamic component burn into vacuum declines, rate of air sucked in required instability, the serious consequence such as even can cause that vavuum pump entirety is scrapped.
Summary of the invention:
The purpose of this utility model is for deficiency of the prior art, provides a kind of acidylate distilling apparatus of stable gas pressure, can prevent vacuum pipe from blocking.
For solving the problems of the technologies described above, the technical solution adopted in the utility model is: a kind of acidylate distilling apparatus of stable gas pressure, and its innovative point is: comprise condenser, first-level buffer tank, level 2 buffering tank and Roots vaccum pump; First-level buffer tank is provided with entrance a and outlet a, and level 2 buffering tank is provided with entrance b and outlet b; Be connected with the entrance a of first-level buffer tank by pipeline a bottom described condenser, the outlet a of first-level buffer tank is by pipeline b and level 2 buffering tank entrance b, and level 2 buffering tank outlet b is connected with Roots vaccum pump.
Further, the inside of described first-level buffer tank and level 2 buffering tank is arranged at and is provided with unicom pipeline, unicom pipeline top is connected with entrance a or entrance b, and first-level buffer tank or level 2 buffering pot bottom are stretched in bottom, and the tube wall of unicom pipeline lower end is provided with some pores.
The beneficial effects of the utility model:
1, the utility model is by arranging two-stage surge tank, can not only effectively prevent logistics solidification and crystallization, can also reduce residual acid value, reduce sour gas directly with vavuum pump drive member contacts, effectively ensure vacuum, raising distilling effect;
2, in surge tank, unicom pipeline can high ensure contact from condenser logistics planning out with the solution in surge tank, and the pore of unicom pipeline lower end is conducive to increase contact area, ensures vacuum further, raising distilling effect.
Accompanying drawing illustrates:
Fig. 1 is the structural representation of the acidylate distilling apparatus of stable gas pressure of the present utility model.
Fig. 2 is the structural representation of the detailed description of the invention of the acidylate distilling apparatus of stable gas pressure of the present utility model.
Detailed description of the invention:
Below in conjunction with accompanying drawing specific embodiment, the technical solution of the utility model is elaborated.
