Definitions
- the invention relates to a continuously operated stirred tank reactor, in particular for the production of polymers of unsaturated monomers, with a preferably temperature-controllable reactor jacket, at least one driven stirrer shaft and rotatably connected to the agitator shaft stirring and / or shear elements, with at least one preferably in the position of use upper Edukteintrag and at least a preferably in use position lower product discharge.
- the invention further relates to a process for carrying out a polymerization reaction of unsaturated monomers using a stirred tank reactor of the type described above.
- a stirred tank reactor of the abovementioned type for carrying out polymerization reactions in highly viscous reaction media and at high reaction rates is known, for example, from DD 294 426 A5.
- the stirred tank reactor described therein has a temperature-controllable reactor jacket and a rotor arranged centrally symmetrically in the reactor.
- the rotor comprises a rotor shaft, a yoke with passage openings and a stirring cylinder, which is open at the top and bottom and extends in the axial direction of the rotor shaft from the reactor bottom to the reactor lid.
- the annular space between the stirring cylinder and the reactor jacket and the annular space between the stirring cylinder and the insertion tube is provided with Rrockchtln.
- the stirring cylinder has a yoke with passages. Between the passage openings on and under the yoke, the mixing elements are arranged. Due to the special arrangement of the passage openings on the yoke the mixing cylinder and the mixing elements, the mixing and homogeneity of the reaction mass and the heat dissipation should be improved.
- the stirred tank reactor according to DD 294 426 A5 is designed so that the reactor can only be operated completely filled.
- the mixing elements must be arranged so that deposits on the reactor cover are avoided.
- the mixing elements must be constructively designed so that effective transport of the product stream can be achieved.
- a partial filling in continuously operated reactors has the disadvantage that polymer deposits can occur in the gas-filled upper tank area.
- Partially filled continuously operated reactors typically require discharge pumps that are quite expensive, especially at high outputs of several 1,000 kg / h of viscous liquid.
- reactor contents When starting and stopping the reactor usually reactor contents must be discharged with compared to the stationary operation very different viscosity. The discharge pump can wear out quite quickly, especially at low viscosities due to lack of lubrication.
- stirred tank reactors are often operated only with a partial filling. For such operation of a stirred tank reactor level gauges are required. These are in turn relatively prone to failure due to the formation of polymer deposits.
- Patent DE 3 338 736 A1 describes a polymerization process in which fully filled stirred tank reactors are used. Thus, although caking on the upper reactor walls and the poor interference of the flowing back Monomerkondensats be avoided. However, not directly below the The mechanical seal is metered in so that it can lead to polymer buildup, which can ultimately lead to failure of the agitator. Since it is driven only with slight overpressure, expensive and maintenance-intensive gear pumps are also used at the bottom of the reactor, which can have high wear and tear especially at low viscosities. Furthermore, the agitator has no grilllager, so that the shaft must be made stronger and the agitator is sensitive to imbalances caused by Polymeranhaftept.
- Patent EP 1 122 265 B1 describes a polymerization reactor which has several inlets for starting materials. However, none of the feeders for flushing the mechanical seal area is used, so that the described disadvantages may occur.
- Patent RU 2114869 C1 describes a continuous bulk polymerization process using fully filled stirred tank reactors. However, here too, no metering in the vicinity of the mechanical seal and no foot bearing is used, as a result of which the abovementioned impairments are likewise to be expected. Returned, cooled polymer solution is fed into the reactor at a second metering point, without mixing initiator. As a result, substantially no improved homogeneity of the initiator concentration in the reactor is produced.
- the invention is therefore based on the object to provide a simply designed stirred tank reactor of the type mentioned, which is operable continuously and completely filled with simple means.
- the reactor should be designed so simple that can be dispensed with expensive syrup pumps for highly viscous liquids and a level control.
- the reactants are to be mixed as quickly as possible in the viscous reaction mixture in the reactor and homogeneously distributed. solution
- the object is achieved by a continuously operated stirred tank reactor, in particular for the production of polymers of unsaturated monomers, with a particular temperature-controllable reactor jacket, at least one driven agitator shaft and rotatably connected to the agitator shaft stirring and / or shear elements with at least one upper position Edukteintrag in use position and with at least one in the position of use lower product discharge, wherein the stirred tank reactor according to the invention is particularly characterized in that the product discharge is designed as a central bottom outlet, which is at least partially penetrated by the agitator shaft.
- the stirred tank reactor according to the invention can be completely filled and operated under pressure.
- the pressure in the reactor is applied by the feeders of the educts, which, due to their conveying properties, ensure that product flows from the reactor into the discharge line. Discharge pumps for the product mixture can therefore be dispensed with.
- At least one educt entry is provided directly in the region of an upper stirring shaft entry in the use position into the reaction space.
- a Edukteintrag be provided immediately below an upper shaft seal the agitator shaft.
- hydrodynamically filled reactors In hydrodynamically filled reactors is thereby avoided that reaction product can get into the shaft seal.
- the lower part of the upper shaft seal is continuously purged by the educt current.
- Hydrodynamically filled reactors are reactors which are completely filled with liquid, without gas phase.
- the stirring shaft forms a part of the bottom outlet at its lower end in the position of use.
- the agitator shaft may be formed, at least at its end passing through the bottom outlet, as a hollow shaft which communicates with the reaction space.
- the foot bearing of the stirring shaft can also be arranged in a further embodiment by a bearing block at a certain height above the bottom outlet.
- the suitably designed as a plain bearing bearings can be cooled and lubricated by the reaction mixture.
- stirred tank reactor according to the invention can be provided that the bearing gap of the contemplat largers is dimensioned so that it can be flowed through by the reaction mixture.
- the agitator shaft additionally has a foot bearing, it is possible to make the diameter of the shaft smaller than would be required for stirring shafts which are guided only in an upper bearing in the position of use.
- the sine larger serves to avoid impermissibly large deflections of the shaft, for example at imbalances introduced into the shaft due to polymerisation deposits in the reactor.
- the stirring shaft has at least one outflow channel opening into the reaction space and extending at least partially transversely to its longitudinal axis.
- the agitator shaft formed as a hollow shaft at at least its lower end can simply be provided with a transverse bore, for example, above the foot bearing.
- the aforementioned object is further achieved by a process for carrying out a polymerization reaction of unsaturated monomers using a stirred tank reactor described above, the process being characterized in particular by the feed of the starting materials and the discharge of the products into and out of the reactor being carried out continuously ,
- the polymerization is carried out under pressure.
- an overpressure of more than 5 bar relative to the atmospheric pressure can be set.
- the reactor is conveniently operated hydrodynamically filled, d. H. that the discharge of the product from the completely filled reactor is accomplished solely by the pressure of the introduced educts.
- a further reactant stream is supplied. It is particularly advantageous if the further educt streams are introduced via at least one metering lance into a central region of the reactor. As a result, poorly mixed points, in which, for example, the initiator concentration is particularly low reliably avoided. Thus, by means of a metering lance a uniform Achieve distribution of the reactants in the reactor. This is especially important for rapidly disintegrating polymerization initiators. Rapid disintegration means in this case that the initiators have half-lives in the range of mixing times of the stirrer. That means about 1 - 200sec.
- the educts prefferably be metered at at least two spatially separate locations of the reactor. By dividing the metering to several metering points better utilization of the reaction volume is possible.
- the initiator fed to the process may be introduced into the monomer feed line of the reactor in pure form or as a dilute solution upstream of the reactor. On the route to the reactor, the initiator is mixed in the monomer line.
- the metering point of the initiator is suitably far enough from the reactor that a homogeneous initiator monomer mixture can form.
- static mixers can be incorporated into the monomer feed line.
- the jacket temperature of the reactor is adjusted so that it is at least 10 ° C above the glass transition temperature of the polymer in the reaction solution. This reduces the tendency for polymer deposits to form on cold reactor walls.

- the reactor shell 2 is composed in the described embodiment of two each double-walled shells 9a and 9b, which are braced against each other via a peripheral flange 10 sealingly.
- the reactor jacket 9a, b flows through a heat exchange medium via which the temperature control of the reaction space 3 is achieved.
- a heat exchange medium can be a heating or cooling medium, for example a tempered fluid such as steam, water, heat transfer oil or another heat transfer medium.
- the agitator shaft 4 is guided at its end remote from the motor 6 in a foot bearing 11, which simultaneously forms a central bottom outlet of the stirred tank reactor 1.
- the design of the foot bearing 11 and the stirring shaft 4 in the area of the foot bearing 11 is shown in FIG.
