Description
Technical field
The ring-like dynamic response device of blade rotor is based on the present invention relates to one kind, it is more particularly to a kind of ring-like with blade rotor
Reaction pipeline replaces the improvement device of traditional still reaction, belongs to field of olefin polymerisation.
Background technology
Olefinic polymerization, mainly addition polymerization, i.e. chain polymerization are reacted, and are that the important polymerization of a class is anti-in high molecular weight reactive
Should.Such as coordination polymerization of the radical polymerization of ethene, the anionic polymerization of styrene, the cationic polymerization of isobutene and propylene
It is olefinic polymerization.In traditional reaction, polymerisation is typically carried out using reactor, the liquid that propylene tank conveying is come
State propylene monomer is input into reactor respectively with catalyst, is then stirred hybrid reaction using paddle, is carried out sufficiently
After stirring reaction, reactor discharging opening, material needed for output are opened.Simultaneously as bulk propylene polymerization is one strongly exothermic anti-
Should, the heat exchange of reactor is poor, and reactor heat transfer problem when volume ratio is less is not serious, in the situation that volume is larger
Under, it is necessary to enhanced heat exchange is carried out using inner cool tube, gas phase outer circulation, liquid phase outer circulation etc..And using device after these measures
Design will be more complicated, and cost can rise significantly.Polyplant maximization and reactor remove heat it is big in the case of, this
The measure of a little enhanced heat exchanges also can not often reach requirement on traditional reactor.On the other hand, in above-mentioned reaction, application
It is traditional reactor, therefore there is dead angle in stirring reaction, material meeting adhesive reaction wall, heat transfer is uneven to cause catalyst
The low drawback of utilization rate, meanwhile, reactor radiates not in time, especially in the reaction big for thermal change, exists certain
Danger, or there are problems that reactivity is low.Patent CN1926159A describes a kind of technology for interconnecting annular-pipe reactor, should
Technology describes a kind of technology in endless tube polyethylene, material is circulated between two endless tubes by the technology, therefore two endless tubes
Between the heat exchange influence of the material that circulates on two endless tubes can almost ignore.But the reaction unit still has material can be adhered to
Reactor wall, heat transfer is uneven to cause the low drawback of catalyst utilization.
At present, the country has largely needs capacity expansion revamping using single loop polypropylene plant, and merely increases ring canal reaction
The quantity of device is improving production capacity, it is clear that can add huge investment and the waste of resource.
The content of the invention
The purpose of the present invention is to design a kind of propylene polymerization device of new construction, the device be shaped as it is ring-like, in ring

Cross fixture, locating part, central shaft to be fixed in tube side, the diameter of blade rotor is slightly less than tube side diameter.When reactant with urge
Agent injecting reactor according to a certain ratio, capacity should not have the blade of Power Drive Unit, can not fill, and leave certain
Space, prevent gas, cause reactor pressure excessive.Power Drive Unit is started working, and drives reactant with catalysis
Agent is flowed in a device, and when flowing is by upper cover, reactant is once converged with catalyst, is then dispersed to straight line
In the tiny tubulation of reactor, driving blade rotor is rotated, and reactant and catalyst are refined under the rotation of blade rotor,
And further differentiation, storeroom contact with each other more fully, while rotor rotate, broken the flow regime of reactant, keep away
Exempt from reactant and be bonded in reaction unit wall；When reactant and catalyst are by low head, then once converged, then
During by another section of straight line reactor, it is reallocated is dispersed in the tiny tubulation of straight line reactor again, mixes anti-again
Should, so it is circulated in reaction unit, until well mixed, reaction is complete.Can install multigroup anti-in straight line reactor
Tube side is answered, specifically can rationally be designed according to integral device size, space left between tube side and ring-like reactor and forms shell
Journey, shell side is connected with external temperature control device, can in a device carry out cold and hot water circulation and gas phase circulation etc. to enter
Row enhanced heat exchange, for controlling reaction temperature.
