To concentration.When charging, circulation fluid and reaction material (gas phase EO or PO) are nebulized by being dispersed in the jet port on reaction vessel top
It sprays, and is concentrated at the one of upper chamber, so that liquid phase dispersion is obvious, avoids and be sprayed into droplet and formed on appts wall
Film, and reaction surface area is reduced, reaction is more sufficiently thoroughly.
Further, the feed system further includes the mixing that the reaction vessel side is arranged in and extends to bottom by top
Expect injection pipe.The mixture injection pipe connects literary mound injector for reacting feeding device early period, with circulation liquid jetting device and
Reaction material injection apparatus mating reaction, circulation liquid jetting device and reaction material injection apparatus work before first by part circulation fluid with
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 greater 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 circulation liquid jetting device includes the extended downwardly by circulation fluid import along reaction vessel inner wall
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 is arranged at intervals on the second endless tube, so that jet port is more evenly distributed in top reaction cavity peripheral wall,
It can guarantee 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.
The utility model has the advantages that compared with prior art, the advantages of the utility model are as follows: firstly, by increasing the upper of reaction vessel
Portion's space size, forms one similar to reaction cavity, and the jet port of peripheral wall in the cavity is arranged towards spraying at one, so that circulation
Liquid and reaction mass can come into full contact with, and the mixture injection pipe that a side is arranged in can also play stirring to lower liquid
Effect keeps reaction more thorough；Secondly, when material is discharged from discharge system, not up to reaction is required, it can be by discharge
Reaction heat is removed by external heat exchanger and is connected to again with circulation fluid import, be passed through reaction vessel by circulating pump by feed liquid, by
Jet port carries out injection hybrid reaction again.
