Description
Technical field
The utility model relates to methanol rectification technical fields, and in particular to a kind of methanol rectification pre-tower backflash extraction dress
It sets.
Background technique
When methanol distills, partial impurities can form azeotropic mixture, the boiling point and methanol boiling point of azeotropic mixture with methanol in crude carbinol
It is closer to, separating difficulty is big, is concentrated mainly on pre- column overhead, then largely enters secondary condenser phegma.
Currently, distillation system extraction water is added in tower with crude carbinol pan feeding from upper section in pre-tower together, this adding manner
Prevent the impurity azeotropic mixture gathered in pre- column overhead and phegma from being efficiently separated, reach tower reactor through phegma, cause into
Main distillation column crude glycol impurity is more, and product quality is influenced when serious.
In order to solve the above problems existing in the present technology, the utility model has developed a kind of methanol rectification pre-tower backflash
Extraction equipment.
Summary of the invention
The purpose of the utility model is to provide a kind of methanol rectification pre-tower backflash extraction equipments.
The utility model is achieved through the following technical solutions：
A kind of methanol rectification pre-tower backflash extraction equipment, including extraction water lines, pre-tower backflash, adding base groove, lye
Slot, lye pump, rectifying pre-tower, DCS control system；
The extraction water lines connect adding base groove by being provided with the pipeline I of regulating valve I, by being provided with regulating valve II
Pipeline II connect lye tank (vat), the lye tank (vat) is connect by being equipped with lye pump conduit IV with rectifying pre-tower, the rectifying
Pre-tower is also connected with alkali pipeline；
The adding base groove is connect by being provided with the pipeline III of regulating valve III with pre-tower backflash, and wherein pipeline III is installed
Before regulating valve I, flowmeter is additionally provided on the pipeline III, the flowmeter is connect with DCS control system.
Further, the pipeline III and pre-tower backflash pass through flanged joint.
The utility model is separately connected lye tank (vat) and adding base groove by threeway after extraction water lines self-adjusting valve, and adds phase
Control valve is answered, a pipeline connection pre-tower backflash is connect before adding base groove regulating valve, is added by flanged joint, and before flange
Control valve, according to the technological requirements, installation flow section are monitored extraction water flow, and with instrument, remote transfer signal is transmitted
To DCS control system.
The utility model optimizes rectifying pre-tower extraction water adding manner, makes total with methanol in pre-tower crude carbinol
The impurity of boiling is further effectively removed, and is effectively increased pre-tower treatment effect, is improved product quality, and can stop transport two extraction waters
Pump, open a received shipment row mode computation by one, every year can power cost saving and maintenance about 70,000 yuan of expense, benefit is evident, operability
By force.
In conclusion the utility model can effectively promote the treatment effect of methanol pre-tower, product quality, energy are further increased
Consume low, strong operability.
