Abstract
The utility model relates to a reaction kettle, in particular to an integrally sealed spray polymerization reaction kettle, mainly solving the technical problems that stirring shafts of reaction kettles must be completely sealed under high pressure during production process whether to adopt a mechanical sealing way or a liquid sealing way, and production process will have potential safety hazardsif materials are combustible explosive dangerous chemicals. The integrally sealed spray polymerization reaction kettle comprises a reaction kettle (1), a feeding pipe (2) is tightly connected with theupper end of the reaction kettle, the lower end of the feeding pipe extends into the reaction kettle, the upper end of the reaction kettle is connected with a circulating pump (3) through a pipeline,the inlet of the circulating pump is connected with a discharge port arranged at the lower end of the reaction kettle (1) through the pipeline, and an absorption port (4) is arranged between the discharge port of the reaction kettle (1) and the circulating pump.
Description
Technical field
The utility model relates to a kind of reactor, especially relates to a kind of isostructural improvement of spray polymerization reactor to integral sealing.
Background technology
Conventional EO/PO polymerization reaction kettle adopts the stirring-type autoclave, and equipment is simple, energy consumption is low, take up an area of province, easy to operate, reduced investment.Chinese patent discloses a kind of gas-liquid that has a combined type paddle or the solid heterogeneous stirred autoclave of gas-liquid (Granted publication number: CN 2483079Y), it is last pushing-type tilted concaved fan disc turbine paddle that the combination of its paddle includes upper and lower two-layer oar, rotating shaft, upper strata oar, lower floor's oar is upper-turn-type axial flow paddle or oblique leaf turbine impeller, is connected in series up and down by rotating shaft between upper and lower two-layer oar; The upper strata oar is 4 to 8 blades, be symmetrically distributed in around the disk, and the blade of its disk top is than the weak point of disk below, the blade sheet is circular arc type or parabolic type concave surface, concave-blade material in the reactor rotates, and the angle e of blade sheet upper and lower end parts line and disk 20 to 90 spends; The lower floor oar adopts upper-turn-type axial flow type paddle or turbine impeller, and 4 to 8 blades are disposed in equilibrium it on, and the angle of each blade and horizontal plane is 20 to spend to 60 and spend; Port in gas feed is provided with many mouthfuls of tubular type finger-types of multilayer gas distributor, and the mouth number of many mouthfuls of tubular type finger-types of multilayer gas distributor is 4 to 12 mouthfuls; Many mouthfuls of tubular type finger-types of multilayer gas distributor is two-layer many mouthfuls of tubular type finger-type gas distributors up and down, the position, upper strata is the still diameter from 0.25 to 0.35 times of Polycondensation Reactor and Esterification Reactor, the lower floor position is the still diameter from 0.15 to 0.18 times of Polycondensation Reactor and Esterification Reactor, from the still span from be about the still diameter 1/100 to doubly being provided with baffle plate within 1/60 scope, barrier width is 1/14 to 1/10 times of still diameter.But no matter shaft adopts mechanical seal or fluid-tight to this reactor, all can't avoid the sealing fully under the device fabrication process high pressure conditions, and EO, PO all is inflammable and explosive dangerous chemicals, and there is certain potential safety hazard in production process.
The utility model content
The utility model technical issues that need to address provide a kind of spray polymerization reactor of integral sealing, it mainly is that no matter shaft adopts mechanical seal or fluid-tight to solution existing in prior technology reactor, all can't avoid the sealing fully under the device fabrication process high pressure conditions, if raw material is inflammable and explosive dangerous chemicals, then can there be the technical problem of certain potential safety hazard etc. in production process.
Above-mentioned technical problem of the present utility model is mainly solved by following technical proposals:
The spray polymerization reactor of integral sealing of the present utility model, comprise reactor, it is characterized in that described reactor upper end is sealedly connected with feed pipe, the feed pipe lower end is stretched in the reactor, the upper end is connected with circulating pump by pipeline, the pump inlet place is connected the discharging opening place of reactor lower end by pipeline, also is connected with material sucking port between reactor discharging opening and the circulating pump.Feed pipe can be many, can feed different raw materials respectively.Wherein feed pipe and circulating pump, reactor are formed the circulatory system, can lead to material repeatedly, until reacting completely.Feed pipe can connect distributor after feeding in the reactor, so both can dispersed material, make that contact is more complete between the material, and save the sealing problem of shaft again.Circulating pump also can be called canned motor pump, replaces traditional stirring system with circulating pump system, by the running of circulating pump, carries out the interior circulation of uninterrupted still of material, thoroughly eliminates the existence in still inner transmission matter dead band.
As preferably, be connected with heat exchanger by pipeline between described circulating-pump outlet place and the feed pipe.Material can carry out heat exchange at circulation time in advance outside reactor, make material enter reactor under suitable temperature, and reaction efficiency is higher.Heat exchanger can be spiral heat exchanger.
As preferably, described inlet of circulating pump and exit all are connected with a ball valve, guarantee that material can only pass through in one direction.
As preferably, by being welded together, sealing property is better like this between described feed pipe and the reactor upper end.
Therefore, the utlity model has and cancelled rotatable parts, the spraying of reaction dependence liquid phase material contacts with the gasification of other material reacts, replace being stirred in the effect in the entire reaction course fully, characteristics such as liquid phase material connects the canned motor pump running circulation of spraying by the reactor bottom in the still, and is simple and reasonable for structure.
Description of drawings
Accompanying drawing 1 is a kind of structural representation of the present utility model.
Parts, position and numbering among the figure: reactor 1, feed pipe 2, circulating pump 3, material sucking port 4, heat exchanger 5, ball valve 6.
The specific embodiment
Below by embodiment, and in conjunction with the accompanying drawings, the technical solution of the utility model is described in further detail.
Embodiment: the spray polymerization reactor of the integral sealing that this is routine, be used for polymerization EO/PO, as Fig. 1, a reactor 1 is arranged, the reactor upper end is connected with feed pipe 2 by welded seal, and the feed pipe lower end feeds in the reactor and connects distributor.The upper end of feed pipe is connected with heat exchanger 5 by pipeline, and heat exchanger import department is connected with circulating pump 3 by pipeline, and pump inlet is connected the lower end of reactor 1 by pipeline.The import of circulating pump 3 and exit all are connected with a ball valve 6, and also are connected with material sucking port 4 between reactor 1 discharging opening and the circulating pump 3.
During use, raw material fed in the reactor 1 react, raw material is gone out from the reactor bottom under the effect of circulating pump 3, carry out heat exchange at heat exchanger 5 places then, reach suitable temperature, enter in the reactor secondary response again by feed pipe 2 again, so circulation is up to reacting completely.
