Abstract
The utility model provides a polypropylene synthesizer of changing line of production in a flexible way, includes dominant reaction ware and side reaction ware, and charge -in system is connected to the dominant reaction ware, still connects main reaction -inhibiting system, main PDS system and RSC system, and resin degasification system still connects tail gas recovery system, and tail gas recovery system includes recovery tower and condenser, the reclaimed materials pipeline after the condenser condensation is carried respectively to dominant reaction ware and side reaction ware. This device has set up connecting tube and control valve between tail gas recovery system and dominant reaction ware, the side reaction ware, and increase through the pipeline makes the device can be according to different product type, and the position that the material was carried is retrieved to decision tail gas to increase the flexibility that the device was changed the line of production.
Description
Technical field
The utility model is related to copolymerization production technical field, is closed more particularly, to change the line of production flexible polypropylene of one kind
Into device.
Background technology
In Unipol technique productions polypropylene process, can production homopolymers and random homopolymers using a main reactor
Product, and properties of product can be made to keep homogeneous in interior regulation operating condition in a big way.Practice finds, using the technique productions
During impact copolymer polypropylene, the propylene that recovery tower is reclaimed has processing mode：1）There is sizing phenomenon to avoid main reactor, will
The propylene that recovery tower is reclaimed retreats to tank field, but occurs in that ethylene contents phenomenon high in the propylene feedstocks of tank field；2）The part is returned
Receive propylene and be delivered to DMTO device freshenings, then cause the waste of DMTO device energy-wastings, if the part propylene not freshening, the material
It is only used for randomly expecting the production of copolymer, this reduces the flexibility that whole Unipol devices are changed the line of production.
The content of the invention
The purpose of this utility model is to overcome shortcoming present in prior art, there is provided a kind of polypropylene synthesizer,
The propylene that the device is reclaimed from tail gas can be recycled in different reactors according to product, flexible with improve that device changes the line of production
Property, the technical scheme of use is：One kind is changed the line of production flexible polypropylene synthesizer, including main reactor and auxiliary reactor, described
Main reactor connects feed system, is also connected with main reaction suppression system, main PDS systems and RSC system, main reactor product
Go down in the control of main PDS systems and Resin Degassing system or through IRTS systems be delivered to auxiliary reactor, auxiliary reactor is from main reaction
Device is fed, and auxiliary connection PDS systems and side reaction suppression system, and auxiliary reactor product is also conveyed through the secondary PDS systems
To Resin Degassing system, the reactant after the treatment of Resin Degassing system is delivered to extruder grain system, the solid product warp of output
Blast system is delivered to finished product packing part packaging, it is characterised in that：The Resin Degassing system is also connected with exhaust gas recovery system,
Exhaust gas recovery system includes recovery tower and condenser, and the condensed pipe material that reclaims of condenser is delivered to main reactor and pair respectively
Reactor.
The technical solution of the utility model also has：Recovered material is delivered to main reactor, warp through controlling valve I and control valve III
Control valve I and control valve II are delivered to auxiliary reactor.
The beneficial effects of the utility model are：The present apparatus is provided with exhaust gas recovery system and main reactor, auxiliary reactor
Between connecting pipe and control valve, by the increase of pipeline cause device can according to different product type, determine tail gas recycle
The position of material conveying, so as to increase the flexibility that device is changed the line of production.
Brief description of the drawings
Accompanying drawing 1 is the utility model structural representation, and accompanying drawing 2 is exhaust gas recovery system structural representation.
Specific embodiment
Below in conjunction with the accompanying drawings, specific embodiment of the present utility model is illustrated.The utility model discloses one kind
Polypropylene synthesizer, the device includes main reactor and auxiliary reactor, and main reactor connection feed system, feed system is responsible for
Including reaction material, major catalyst, triethyl aluminum and electron donor etc., main reactor is also connected with main reaction suppression to the raw material of supply
System processed, main PDS systems and RSC system, main reactor product main PDS systems control go down Resin Degassing system or
Auxiliary reactor is delivered to through IRTS systems, auxiliary reactor feeds from main reactor, and auxiliary connection PDS systems and side reaction suppress system
System, auxiliary reactor product is also delivered to Resin Degassing system through the secondary PDS systems, anti-after the treatment of Resin Degassing system
Thing is answered to be delivered to extruder grain system, the solid product of output is delivered to finished product packing part and packs through blast system.Resin takes off
Gas system is also connected with exhaust gas recovery system, and exhaust gas recovery system includes recovery tower and condenser, the condensed reclaimed materials of condenser
Can pipeline to it is following everywhere：1）Main reactor and auxiliary reactor, i.e. recovered material are delivered to respectively after controlling valve I through control
Valve processed I and control valve III are delivered to main reactor, are delivered to auxiliary reactor through control valve I and control valve II；2）Go tank field conduct
Raw material is directly used；3）Recovered FF（Slough the impurity such as ethane therein）Tank field is gone to after treatment.
The design of control valve and pipeline more than, tail gas recycle material can be subject to spirit according to the difference of device product type
Selection living.
Certainly, described above is not limitation of the utility model, and the utility model is also not limited to the example above, this skill
Change, remodeling, addition or replacement that the those of ordinary skill in art field is made in essential scope of the present utility model, also belong to
In protection domain of the present utility model.
