Description
Technical field
A kind of carbon five separating and extracting unit polymerization inhibitor adding apparatus, belongs to polymerization inhibitor and adds equipment technical field.
Background technology
Be rich in the diolefins such as isoprene, cyclopentadiene and pentadiene in C 5 fraction, these diolefin chemical property are active, are the valuable sources of chemical utilization.C 5 fraction is close by more than 20 kinds of boiling points, easily form again the component composition of azeotropic mixture each other, and the double olefin compounds such as isoprene have the structure of conjugated diolefin, interact under heat, oxygen and metal ion cause, autohemagglutination or be copolymerized into polymer (colloid), the situation of appearance equipment kiss-coating blocking, brings adverse effect to production.
Add polymerization inhibitor obviously to reduce the autohemagglutination of diolefin in carbon five is separated and be copolymerized into phenomenon, decrease the stopping state of separating and extracting equipment, but the method for common interpolation polymerization inhibitor has very large deficiency, price because of polymerization inhibitor is high and use amount is also quite large, which adds the cost dropped on carbon five is separated, and consumption increases load greatly also can to former carbon five separator.
In the prior art, general employing adds some composite polymerization inhibitor to suppress the polymerization of olefines in material, more commonly adopts p-tert-butyl catechol and natrium nitrosum to realize polymerization inhibition effect.But its polymerization inhibition effect is unsatisfactory, in material, hydrocarbon-based polymeric still clearly, and seriously, cleaning equipment is very complicated, and cleaning up cost is also very high for equipment kiss-coating, blocking.
Utility model content
The technical problems to be solved in the utility model is: overcome the deficiencies in the prior art, provides that a kind of loss of material is little, device is without kiss-coating, carbon five separating and extracting unit polymerization inhibitor adding apparatus that polymerization inhibitor use amount is little.
The utility model solves the technical scheme that its technical problem adopts: this carbon five separating and extracting unit polymerization inhibitor adding apparatus, it is characterized in that: comprise the solid polymerization inhibitor dissolving tank, the polymerization inhibitor that are linked in sequence and add pump, polymerization inhibitor and divide storage unit and measuring pump, the measuring pump port of export is divided into extractive distillation column or the solvent surge tank that many pipelines connect carbon five separating and extracting equipment respectively.
Described polymerization inhibitor divides storage unit to comprise an extraction polymerization inhibitor interpolation tank and two extraction polymerization inhibitors interpolation tanks, and an extraction polymerization inhibitor interpolation tank and two extracts polymerization inhibitors and adds tanks parallel connection and the corresponding feed(raw material)inlet being connected to measuring pump respectively by respective pipeline.
The polymerization inhibitor that the utility model can allocate different ratio is respectively respectively allocated in different polymerization inhibitor interpolation tank, distributed in demand uses, inhibitions different in carbon five separating and extracting equipment is required that realizing specific aim adds, polymerization of olefines can not only be suppressed preferably, reduce total use amount of polymerization inhibitor simultaneously, the kiss-coating stopping state of equipment can be reduced, and can also avoid increasing extra load to device.It is the process of extractant extracting distillation separation C five cut that the utility model is more suitable for DMF.The carbon five separating and extracting unit polymerization inhibitor adding apparatus that the utility model provides, adds dissolution kettle in the polymerization inhibitor adding set of extracting rectifying unit.Solid polymerization inhibitor is dissolved in liquid polymerization inhibitor.Can be arranged in pairs or groups by solid, liquid polymerization inhibitor, adjusting different active constituent content increases specific aim, reduces total consumption of polymerization inhibitor.
The described measuring pump port of export is divided into four pipelines, and four pipelines connect in the first extractive distillation column of carbon five separating and extracting equipment the device that boils, the first extractive distillation column solvent surge tank, the second extractive distillation column reboiler and the second extractive distillation column solvent surge tank respectively.
Compared with prior art, the beneficial effect that carbon five separating and extracting unit polymerization inhibitor adding apparatus of the present utility model has is: the utility model dissolves owing to being provided with solid polymerization inhibitor, the relatively cheap solid polymerization inhibitor of price can be added in liquid polymerization inhibitor, and then can active ingredient in solid polymerization inhibitor dissolves in regulates liquid polymerization inhibitor and content.Under the prerequisite reaching better polymerization inhibition effect, decrease the use amount that polymerization inhibitor is total, reduce production cost.The utility model is provided with multiple polymerization inhibitors in parallel and adds tank, solid, liquid two kinds of polymerization inhibitor collocation can be used, while minimizing polymerization inhibitor total addition level, decrease wherein non-active ingredients on the impact of whole carbon five separation of material system, indirectly reduce the segregational load of extractive distillation column, improve product quality.
