Invention content
Goal of the invention：In order to overcome the shortcomings of background technology, the invention discloses a kind of reaction is more efficient and more thorough
The polyether reactant device of reaction efficiency is improved to reduce the cycle-index of circulation fluid in bottom.
Technical solution：Efficient polyether reactant device of the present invention, including cylindric closed reaction vessel, setting are in institute
It states the feed system on reaction vessel top and the discharge system in the reaction container bottom is set, the feed system includes
Be arranged end face on the reaction vessel circulation fluid import and reaction material import and setting reaction vessel interior respectively with cycle
Liquid import, the cycle liquid jetting device of reaction material inlet communication, reaction material injection apparatus；The cycle liquid jetting device and reaction
Material injection apparatus includes the jet port of multiple inner wall scattering devices of portion on the reaction vessel, the injection direction collection of the jet port
In.When charging, circulation fluid and reaction material (gas phase EO or PO) are nebulized ejection by being dispersed in the jet port on reaction vessel top,
And concentrated at the one of upper chamber so that liquid phase dispersion is apparent, avoids and is sprayed into droplet and forms film on appts wall, and subtracts
Few reaction surface area, reaction is more fully thoroughly.
Further, the feed system further includes that the mixing for extending to bottom by top in the reaction vessel side is arranged
Expect injection pipe.The mixture injection pipe for reacting the literary mound injector of feeding equipment connection early period, with cycle liquid jetting device and
Reaction material injection apparatus mating reaction, before cycle liquid jetting device and the work of reaction material injection apparatus first by part circulation fluid and
Reaction material carries out hybrid reaction and is delivered to reaction container bottom, and is passed through in side and can also play stirring to lower liquid
Effect, and growth ratio can be improved, be conducive to manufacture high molecular weight products.
Further, the top of the reaction vessel is the spherical cavity body structure that internal diameter is more than middle and lower part barrel bore,
The injection direction of the jet port concentrates at the centre of sphere of spherical cavity.Spherical cavity formation one is relatively independent and volume is larger
Liquid phase contact chamber.
Further, the cycle liquid jetting device includes the extended downwardly into opening's edge reaction vessel inner wall by circulation fluid
One endless tube and multiple the second rings being surround by peripheral wall at the top of reaction vessel and axially lower interval is arranged and is connected to the first endless tube
Pipe, the jet port are arranged at intervals on the second endless tube so that and jet port is more evenly distributed in top reaction cavity peripheral wall,
It can ensure coming into full contact with for circulation fluid and material when spraying of material.
Further, multiple fixed ear bases are arranged in the appearance face interval of the reaction vessel, also set up catalyst inlet, pressure
Power table interface, vacuum nozzle.
Advantageous effect：Compared with prior art, advantages of the present invention is：First, empty by increasing the top of reaction vessel
Between size, form one similar to reaction cavity, and the jet port of peripheral wall in the cavity is set towards spraying at one so that circulation fluid and
Reaction mass can come into full contact with, and the stirring that the mixture injection pipe in a side can also be played to lower liquid is arranged and makees
With keeping reaction more thorough；It secondly, can be by the material of discharge when material is discharged from discharge system, not up to reaction requires
Reaction heat is removed by external heat exchanger and is connected to again with circulation fluid import, be passed through reaction vessel, by being sprayed by circulating pump by liquid
Loophole carries out injection hybrid reaction again.
