Description
Technical field
The utility model is related to a kind of amine purification processing systems, more particularly to using makes in organic amine flue gas desulfurization technique
The purification restoring system of amine liquid.
Background technology
It is industrial largely to use organic amine flue gas desulfurization.In use, due to containing SO3 in flue gas, into amine liquid
Middle formation sulfate ion, can not regenerate, these sulfate ions are built up in systems, influence amine liquid desulfurization performance, add
Acute equipment corrosion.The following two method processing of generally use on commercial plant：
First, after sulfate radical is accumulated to a certain extent, certain salt is added into amine liquid, to generate sulfate precipitation, to
The concentration of sulfate radical is reduced, this method can introduce other impurity in amine liquid；
Second is that the method using ion exchange removes sulfate radical, this method will produce a large amount of waste water.
Utility model content
The utility model mainly solves the deficiencies in the prior art, provides a kind of purification resurrection of organic amine liquid
System can reduce three waste discharge while purifying amine liquid.
The technical solution adopted in the utility model is：A kind of flue gas desulfurization amine purification restoring system, including level-one are accurate
Candle filter, absorbent charcoal adsorption tank, two level precision Filter element filter, electrodialysis system, pollution amine liquid feed pipe and purification amine
Liquid discharge nozzle；
The level-one precision Filter element filter, absorbent charcoal adsorption tank, two level precision Filter element filter, electrodialysis system are successively
Connection, the import of the level-one precision Filter element filter are connect with pollution amine liquid feed pipe, the outlet of the electrodialysis system and
Purify the connection of amine liquid discharge nozzle.
Preferably, the level-one precision Filter element filter is the filter that filtering accuracy is 50 μm.
Preferably, the absorbent charcoal adsorption tank is absorption amine liquid catabolite, amine liquid polymer organic impurity, chelate iron
Adsorption tanks.
Preferably, the two level precision Filter element filter is the filter that filtering accuracy is 1 μm.
Preferably, the electrodialysis system is the electrodialysis system for removing the ionic species impurity in amine liquid by electrodialysis
System.
Advantageous effect：Amine liquid is handled using the device of the utility model, without consuming other chemicals, whole process only has
The discharge of strong brine waste water, and discharge capacity only has 1/10th or so of ion-exchange resin technique discharge capacity, environmental protection pressure is very
It is small.
Description of the drawings

Specific implementation mode
The utility model is described in further detail with reference to the accompanying drawings and detailed description.
As shown in Figure 1, a kind of flue gas desulfurization amine purification restoring system, including level-one precision Filter element filter 1, activated carbon
Adsorption tanks 2, two level precision Filter element filter 3, electrodialysis system 4, pollution amine liquid feed pipe 5 and purification amine liquid discharge nozzle 6；
The level-one precision Filter element filter 1, absorbent charcoal adsorption tank 2, two level precision Filter element filter 3, electrodialysis system 4
It is sequentially connected, the import of the level-one precision Filter element filter 1 is connect with pollution amine liquid feed pipe 5, the electrodialysis system 4
Outlet is connect with purification amine liquid discharge nozzle 6.
It pollutes amine liquid and enters level-one precision Filter element filter 1 from pollution amine liquid feed pipe 5, filter off miscellaneous more than 50 μm of particle
After matter, into absorbent charcoal adsorption tank 2, organic impurities therein etc. is adsorbed, subsequently into two level precision Filter element filter 3, filter
The granule foreign more than 1 μm is removed, electrodialysis system 4 is finally entered, removes sulfate radical plasma impurity therein, purified amine
Liquid is discharged by purification amine liquid discharge nozzle 6.
The embodiment of the utility model is described in detail above in association with attached drawing, but the utility model is not limited to institute
The embodiment of description.For those of ordinary skill in the art, in the range of the principles of the present invention and technological thought
It is interior, a variety of variations, modification, replacement and deformation are carried out to these embodiments and still fallen in the scope of protection of the utility model.
