Abstract
The utility model relates to a polymerization kettle with internal cool mixer, which comprises a polymerization kettle body with a jacket and a mixer arranged inside the polymerization kettle body. The utility model is characterized in that the mixer is of a hollow structure with a cooling water flowing passage; the utility model has a simple structure, an easy fabrication process and an easy operation, the other structure of the prior polymerization kettle is not changed, only the mixer is arranged into the hollow type, the cooling water in the utility model can assist to draw out a certain amount of heat of polymerization.
Description
Technical field
The utility model belongs to the polyplant that chemical industry is used, and relates generally to the polymerizer equipment of very exothermic system.
Background technology
The polymerizer equipment of prior art, the main jacket of polymerization mode that adopts is removed heat, the violent jacket of polymerization that system adopted of heat release is made halfpipe or built-in deflector usually, and takes to be provided with in polymeric kettle such as measures such as cooling coil or still outer circulation cooling reaction masses in order to strengthen heat-transfer effect.These measures have all brought very big inconvenience, particularly cooling coil to operation, cause easily such as a large amount of wall cling phenomenons of the material of emulsion, slurry polymerization system, have not only influenced heat-transfer effect, also make product quality to ensure, have increased operation easier.It mainly is homogeneous material, promotion polymerization that agitator is set in polymeric kettle.
Summary of the invention
Technical problem to be solved in the utility model provides the polymeric kettle of cold agitator in a kind of having, and implements easily, and is easy and simple to handle, can assist effectively and withdraw from heat of polymerization.
The polymeric kettle of cold agitator in of the present utility model having comprises the polymerization kettle that has chuck, is arranged on the agitator in the still, it is characterized in that described agitator is a hollow structure, has the cooling water flow circulation passage.
Polymerization kettle of the present utility model has chuck, mainly be to adjust the temperature that the control polymerisation requires, its form still is provided with charging aperture, discharging opening, pick-up hole, temperature measuring hole or the like parts according to instructions for use such as prior art mode with the variety of way of prior art on the kettle (comprising kettle cover).Major technique characteristics of the present utility model are with the inner cooling water that feeds of the agitator with agitating function, to take away the heat of polymerization of a great deal of.
Described agitator generally is made up of shaft and stirring blade, and shaft and stirring blade all have hollow structure, to increase cooling effect.The shape of stirring blade and installation form can be as the variety of ways of prior art, but in order to make better, to install, preferably agitator are made into shapes such as anchor formula, frame, stirring blade are located at the bottom of polymerization kettle.
For the ease of using and installing, in agitator, be preferably formed as the circulation canal of cooling water, cooling water advances from the upper end position of shaft, go out by the upper end diverse location again, described shaft can be made of the concentric tube of two hollow shape different-diameters, form central passage and outer wall interlayer, stirring blade communicates with the central passage of shaft, and the passage that communicates with the outer wall interlayer is also arranged.The cooling water flow that feeds central passage by shaft upper end is through stirring blade like this, and last flows out from the shaft upper end with converging the outer wall interlayer of cage to shaft again, forms and circulates.
In order to increase mixing effect and mixed effect, can increase the stirring fin again on the shaft, relatively be fit to the polymeric kettle of big volume; Shaft is or/and can have heat-dissipating fin on the outer wall of stirring blade.
Advantage of the present utility model:
Simple in structure, it is easy, easy to operate to make, and does not change other structure of polymeric kettle, just agitator is arranged to hollow form, and the cooling water in it can be assisted the heat of polymerization of withdrawing from a great deal of.This polymeric kettle can be used as the reactor of batch (-type) or continous way polymerization, its internal structure has determined that this reactor has bigger effective reaction space, be applicable to the polymerization system that reaction is comparatively fierce, use this reactor can not produce more sticking wall material, its range of application and production capacity are higher, be not only applicable to gas-solid phase chemistry reaction, also applicable to liquid-solid phase, liquid-liquid phase reaction, and gas-liquid-solid phase reaction.This polymeric kettle is fit to the most is as the olefinic monomer reactor of vinyl monomer (slurry) polymerization particularly.
Description of drawings
Fig. 1, Fig. 2 are respectively structural representation of the present utility model;
Among the figure: 3 stirring blades, 4 passages, 5 polymerization kettlies, 6 discharging openings, 7 central passages, 8 outer wall interlayers, 9 heat-dissipating fins, 10 blades of 1 shaft, 2 stirring blades bottom
The specific embodiment
Fig. 1, Fig. 2 are example structure schematic diagram of the present utility model, below in conjunction with description of drawings:
Polymerization kettle 5 (having chuck), its inside is provided with agitator, and agitator connects power set, makes its rotation.Because the utility model is except the structure of agitator changes, all the other structures and occupation mode, function all do not change, and can therefore, omit other structure as the various forms of prior art, only more clearly give expression to a kind of version of agitator.
As Fig. 1, agitator is made up of shaft 1 and stirring blade 3, and shaft 1 is to be made of two inner small and outside big hollow concentric garden pipes, forms central passage 7 and outer wall interlayer 8 spaces.Stirring blade 3 is the hollow pipe-type structure of circle or noncircular cross section, communicate with central passage 7 in its bottom, be communicated with the outer wall interlayer 8 of shaft by passage 4 on top, the outer wall interlayer of passage below 4 can be the space that do not communicate, and the arrow among the figure has been represented the flow direction of cooling water.Cooling water is flowed through stirring blade bottom 2, stirring blade 3, passage 4 remittance cages to outer wall interlayer 8 discharge polymeric kettles by the upper end (swivel joint place) of shaft along central passage 7.
Fig. 2 is on the basis of Fig. 1, increases blade 10 (stir fin, also belong to stirring blade, but can obstructed cooling water) on shaft again, increases heat-dissipating fin 9 to improve cooling effect on stirring blade 3.Increase just signal of blade Fig. 2 on shaft, the general bigger polymeric kettle of suitable space improves stirring and mixed effect by blade.
