Abstract
A kind of device that can be carried out on-line monitoring analysis to heavy constituent in ethylene glycol kettle raffinate and automatically switch storage tank, the present apparatus is analyzed using on-line chromatograph and carries out on-line monitoring analysis processing to heavy constituent in ethylene glycol kettle raffinate, have many advantages, such as that separative efficiency is high, save the plenty of time, separative efficiency is improved, pollution has not only been reduced but also has saved resource.
Description
Technical field
The utility model relates to the devices that the heavy constituent in a kind of pair of ethylene glycol kettle raffinate is separated, and relate generally to one kind
The device that storage tank is automatically switched in on-line monitoring analysis can be carried out to heavy constituent in ethylene glycol kettle raffinate.
Background technique
Ethylene glycol can synthesize cosmetics, and explosive is a kind of important organic basic material.In industrial production, rectifying column essence
Product and ethylene glycol after evaporating, butanediol.In the recycling field of ethylene glycol kettle raffinate, the rate that is recycled of various components
Be not it is very high, technical grade ethylene glycol content generally all 90% or more, and in ethylene glycol kettle raffinate the content of ethylene glycol 60% ~
70%.All the time, in ethylene glycol kettle raffinate heavy constituent can not effective separation.This experiment novel pin to this situation, if
A kind of device that can be carried out on-line monitoring analysis to heavy constituent in ethylene glycol kettle raffinate and automatically switch storage tank is counted, chromatography point is utilized
The advantages of analysis has good separating effect, easy to operate, mild condition.To each content of material carry out real-time monitoring, by with control
Analysis system connection realizes that data point is synchronous, controls the switch of suction pump and corresponding storage tank valve, and then automatically switch storage tank.Section
The plenty of time has been saved, separative efficiency is improved, has brought great convenience for factory.
Summary of the invention
A kind of device that can be carried out on-line monitoring analysis to heavy constituent in ethylene glycol kettle raffinate and automatically switch storage tank, it is main to wrap
It includes: waste tank, filter, infusion pump, sample injector, chromatographic column, detector, logger, valve, suction pump, control analysis system
System；It is characterized by: waste tank and filter are connected to a fixed by conduit；Filter is connected with infusion pump by conduit
It connects；Infusion pump is connected with sample injector by conduit；Sample injector is connected with chromatographic column by conduit；Chromatographic column and detector are logical
Conducting wire is crossed to be connected；Detector is connected with logger by conducting wire；Detector is connected with storage tank by conducting wire；Storage tank and pumping
Water pump is connected by conduit；Logger, valve, suction pump are connected with control analysis system respectively.
When work, the liquid phase feed from falling film evaporator enters tails batch column storage tank, and mobile phase passes through after sample introduction
Infusion pump enters sample injector through filter, flows through chromatographic column, is adsorbed in the chromatography column, separation, last each group of component point
Device is not changed into electric signal after testing, shows this reflection to recording device through chromatographic column.By being connect with control analysis system,
It realizes on-line real time monitoring, by the switch of control analysis system control suction pump and respective valves, reaches data point and synchronize, thus
Realize the effect of switching storage tank.
