Abstract
The utility model discloses a distillation device system for recovering chloroactic acid mother liquor. The distillation device system comprises a distillation still, a distillation tower, a river water condenser, a 5 DEG C water condenser, a mother liquor tank, a low-boiling matter storage tank and a high-boiling matter storage tank, wherein a feed port, a discharge port and a gas phase outlet of the distillation still are respectively communicated with the feed ports of the mother liquor tank, the high-boiling matter storage tank and the distillation tower, a discharge port and a gas phase outlet of the distillation tower are respectively communicated with the low-boiling matter storage tank and the river water condenser, and the 5 DEG C water condenser is communicated with the river water condenser. The distillation device system disclosed by the utility model has the advantages of well recovering useful chloroactic acid in the chloroactic acid mother liquor, being operated normally and stably for a long time due to better corrosion resistance of graphite materials against the mother liquor, ensuring the recovery utilization of the chloroactic acid mother liquor and reducing the production cost of a chloroactic acid product. The single-still productivity of the chloroactic acid obtained after the process steps of crystallization, centrifugation and the like are performed on the mother liquor after distillation can be improved by above 60% in comparison with the chloroactic acid recovered from the mother liquor which is not distilled, and the product quality can be improved from substandard products to qualified products.
Description
Technical field
The utility model relates to a kind of distilling apparatus system of chemical industry, particularly a kind of distilling apparatus system of mother liquor of chloroacetic acid recovery.
Background technology
Can produce mother liquor after the centrifugation in the chloroacetic acid by intermittent process production technology, mother liquor will recycle, and reclaims wherein useful monoxone.Mother liquor reclaims the main destilling tower that adopts and carries out batch distillation, and the low-boiling-point substances such as the moisture content in the mother liquor and acetic acid are at overhead extraction, and the high-boiling components of tower reactor was pressed into crystallization kettle and is cooled to set point of temperature after distillation finished, and through centrifugation, liquid phase is waste liquor, outwards sells.
Existing distilling apparatus system distillation still and the destilling tower that is used for the mother liquor of chloroacetic acid recovery all is the enamel material, because the mother liquor distillation requires high to equipment material, enamel equipment is all not long service life, Distallation systm is in out the state that start-stop stops always, all the time can't run well, can not satisfy the recycling of mother liquor of chloroacetic acid, increase monoxone production cost.
The utility model content
The utility model purpose: for the problems referred to above, the purpose of this utility model provides a kind of distilling apparatus system of mother liquor of chloroacetic acid recovery that can be long-term, obtains monoxone useful in the mother liquor of chloroacetic acid.
Technical scheme: the distilling apparatus system that a kind of mother liquor of chloroacetic acid reclaims, comprise distillation still, destilling tower, river condenser, 5 ℃ of water condensers, mother liquor tank, low-boiling-point substance storage tank, high-boiling components storage tank, the charging aperture of described distillation still, discharging opening, gaseous phase outlet are communicated with the charging aperture of described mother liquor tank, described high-boiling components storage tank, described destilling tower respectively, the discharging opening of described destilling tower, gaseous phase outlet are communicated with described low-boiling-point substance storage tank, described river condenser respectively, and described 5 ℃ of water condensers are communicated with described river condenser.
Described distillation still, described destilling tower are graphite material.
Described distillation still arranges two.
Beneficial effect: compared with prior art, the utility model has the advantages that and to reclaim well monoxone useful in the mother liquor of chloroacetic acid, because graphite material is better for the corrosion resistance of mother liquor, so that for a long time normal stable operation of distilling apparatus, both guarantee the recycling of mother liquor of chloroacetic acid, reduced again the production cost of monoxone product.Monoxone output per single reactor after the monoxone output per single reactor that mother liquor after the distillation obtains after through crystallization, the operation such as centrifugal reclaims than undistilled mother liquor improves more than 60%, and product quality is also brought up to certified products from off standard.
Description of drawings
Accompanying drawing the utility model distilling apparatus system architecture schematic diagram.
The specific embodiment
Below in conjunction with the drawings and specific embodiments, further illustrate the utility model, should understand these embodiment only is used for explanation the utility model and is not used in restriction scope of the present utility model, after having read the utility model, those skilled in the art all fall within the application's claims limited range to the modification of the various equivalent form of values of the present utility model.
As shown in drawings, the distilling apparatus system that a kind of mother liquor of chloroacetic acid reclaims comprises distillation still 1, destilling tower 2, river condenser 3,5 ℃ of water condensers 4, mother liquor tank 5, low-boiling-point substance storage tank 6, high-boiling components storage tank 7.Distillation still 1 arranges two, and the charging aperture 8 of distillation still 1 and mother liquor tank 5 are communicated with by feed pipe, and the discharging opening 9 of distillation still 1 and high-boiling components storage tank 7 are communicated with by discharge nozzle, and the gaseous phase outlet 10 of distillation still 1 passes through pipeline communication with the charging aperture 11 of destilling tower 2.The discharging opening 12 of destilling tower 2 is communicated with by the extraction pipe with low-boiling-point substance storage tank 6, and the gaseous phase outlet 13 of destilling tower 2 is communicated with by the gas phase pipe with river condenser 3.5 ℃ of water condensers 4 are communicated with river condenser 3.Distillation still 1, destilling tower 2 adopt graphite material.
The utility model distilling apparatus system controls the water content of the mother liquor of tower reactor by the size of control distillation still temperature and control destilling tower overhead extraction amount.Graphite material is better for the corrosion resistance of mother liquor, so that for a long time normal stable operation of distilling apparatus.
7.5 tons of the monoxone output per single reactor average out to that mother liquor after the distillation obtains after through crystallization, the operation such as centrifugal, quality can reach the certified products standard, and without 4.5 tons of the monoxone output per single reactor average out to of the mother liquor that distills after reclaiming, quality mostly is off standard, can find out that the yield after the mother liquor distillation improves more than 60% than undistilled yield, product quality is also brought up to certified products from off standard.
