Description
Technical field
The present invention relates to the polycondensation reaction device in a kind of production of polyester.
Background technology
In the prior art, a kind of horizontal reacting tower that is used for production of polyester is arranged, mainly comprise the housing that has chuck that can feed heating medium, cylindrical and the horizontal setting of housing, the two ends of housing are respectively equipped with end cap, and end cap is provided with the charging and discharging mouth, top at end cap or housing is provided with vacuum pumping opening, one is stretched in the housing by the rotating shaft of the driven by motor end cap that axially passes along housing, and the rotating shaft two ends are provided with and the relatively-stationary pedestal bearing of housing, and rotating shaft is provided with stirring parts.During this device busy, heat for the intravital reaction mass of shell, it is reacted under suitable temperature by chuck; Material enters in the housing from opening for feed, under the effect of vacuum suction device, keeps certain vacuum tightness in the housing, stirs through whipping appts, has promoted the effusion of byproduct of reaction, has accelerated the carrying out of reaction, and the product after reaction finishes is from the discharge port separating device.Because reacted material viscosity is big, make stirring parts stir difficulty, it is big to stir resistance, needs to be equipped with the very big motor of power, and its power consumption is very big; In addition, the dead angle that responds in the housing, the material evaporating space is little, and reaction efficiency is low, and is less economical.
Summary of the invention
It is big to the purpose of this invention is to provide a kind of evaporating space, and reaction interface is upgraded a kind of polymerization tower that the rapid polycondensation that also can satisfy multiple different polyester products requires.
The object of the present invention is achieved like this: a kind of polymerization tower, comprise the housing that has chuck that can feed heating medium, housing is cylindrical, the two ends of housing are respectively equipped with end cap, one is stretched in the housing by the rotating shaft of the driven by motor end cap that axially passes along housing, the rotating shaft two ends are provided with and the relatively-stationary pedestal bearing of housing, described housing uprightly is provided with, the end cap on housing top or housing top is provided with opening for feed and vacuum pumping opening, the end cap of lower housing portion is provided with discharge port, level is provided with several layers rotation tower tray in the rotating shaft, and described rotation tower tray is provided with some blanking channels, leaves airspace between the rotation tower tray outside and the inner walls; Be provided with above one deck rotary column dish at least and be distributed into an act device, the described act device that is distributed into is conical panel from outside to inside by one deck at least and forms, and panel is provided with some circular holes or strip hole.
During this device busy, heat for the intravital reaction mass of shell, it is reacted under suitable temperature by chuck; Material enters in the housing from opening for feed, under the effect of vacuum suction device, keep the certain vacuum degree in the device, fluid foods is in the opening for feed access to plant, blanking channel process from each layer tower tray forms bigger tentiform or the curtain shape of surface-area, react the clear steam that goes out outside the rotation tower tray and the airspace that leaves between the inner walls upwards compile, and extracted out by vacuum suction device, material carries out polyreaction in device finishes until reaction; When material drops down onto when being distributed on act device, material is waved the fermentation sheet being distributed on act device upper surface to form, simultaneously, material is by circular hole on the panel or strip hole, can form tentiform, the evaporation surface that can enlarge markedly material is long-pending, makes steam be able to abundant volatilization from the bigger material of viscosity.The preferred version of technique scheme is: the top of the superiors rotations tower tray is provided with is distributed into act device and rotating shaft fixes, and all the other are distributed into act device and inner walls fixes; Material has just entered easier uniformly distributing in the housing like this, and act interlaced the carrying out that move into that is fixed into curtain and rotation tower tray that is distributed into act device subsequently plays better stirring action, can make reaction more even, the reaction efficiency height.Downward from the upper strata tower tray, the viscosity of material increases gradually, and the polymkeric substance after reaction is finished leaves from discharge port and enters down the road flow process.Because rotating shaft is upright with the upright setting of housing, it is little to rotate torque when rotating, and the power of motor of outfit can be smaller, can save energy; The design of tower tray makes material become tentiform or curtain shape, material can thorough mixing, and have enough big evaporation surface, can make reaction more thoroughly, evenly, no back-mixing, no flow blind angle, the residence time of material in tower is short, the reaction efficiency height, and temperature of reaction is controlled, harmful side reaction is few, good product quality.The present invention can place on the spot outdoor, need not to be installed in the factory building, and laying in the open for poly-unit becomes possibility.The present invention not only can be used for the PET polymerization, also can be applied to the polymerization of products such as PTT, PBT.
Described blanking channel can be circular hole; Also can be strip hole; Can also be that the blanking channel that is positioned at housing top is a circular hole, the blanking channel that is positioned at lower housing portion be a strip hole.Circular hole and strip hole are easy to processing, are easy to into curtain in the use.
The material viscosity on housing top is low, the viscosity height of lower housing portion material, and the spacing between the described tower tray increases from the top down gradually.Help flowing of material so more, can guarantee that material evenly flows between individual layer tower tray.
