Problems solved by technology

Therefore, when the parameter circulation ratio is on the low side, that is, when the reaction feed rate is higher than the design value, a short circuit phenomenon is prone to occur, causing side reactions to occur, and the amount of gel or insoluble matter generated is therefore difficult to control
In addition, when the solvent of the reaction feed is a poor solvent (such as cyclohexane, butene-1, cis-2-butene, etc.), the flow behavior of this design is very unsuitable for the production of polymer products with particularly low fine gel content
[0004] Facing the increasingly competitive commercial market and strict environmental protection requirements, the design process claimed by the currently used reaction tank can no longer meet the technical and market needs

Embodiment Construction

[0056] see figure 2 , which is a schematic diagram of a preferred polymer polymerization tank of the present invention. Among them, the reaction tank is composed of a tank body cover 21, a crossbeam 22, a frequency conversion motor 23, a pair of ribbon-shaped stirring wings 24, a scraper pillar 25, a liftable tank body 26, a stirring central axis 27, a tank The inner interlayer 28 and a groove-side interlayer 29 are formed.

[0057] When desiring to carry out macromolecule polymerization reaction, tank body 26 can rise to such as figure 2 As shown, it is closely combined with the upper cover 21 of the tank body. At this time, the stirring central shaft 27 fixed inside the tank body, the plug at the top will also be inserted into the shaft seal 232 of the transmission shaft 231 of the frequency conversion motor 23, so that the stirring central shaft 27 is in contact with the tank body. Combined and fixed on the crossbeam 22, it is used to balance the inertial centrifugal fo...

Abstract

The invention provides an improved high polymer polymerization reacting groove, comprising a pair of ribbon shape impeller, and the rotating speed of the impeller can be regulated according to different requirement; besides, the high polymer polymerization reacting groove is provided with a plurality of devices that can improve the overall heat transfer coefficient, the polymer polymerization reacting groove of low skim coating quantity, high overall heat transfer coefficient, and producing the diversified high quality products is composed.

Description

technical field [0001] The invention relates to a polymer polymerization reaction tank, in particular to a polymer polymerization reaction tank which has a pair of ribbon-shaped stirring wings and whose rotational speed can be adjusted. Background technique [0002] Generally, polymer polymerization methods use block polymerization and solution polymerization. For example, monomer materials are styrene, butadiene, isoprene, vinyl chloride, etc. chloride) and so on. With the evolution of the polymerization reaction of these monomers, the overall solution will gradually become a high-viscosity polymer viscous fluid. Therefore, during the stirring reaction, movements such as mixing, convection, and heat transfer become relative. difficulty. As a result, it is difficult to maintain a stable temperature control of the reaction tank during the polymerization reaction, and the temperature gradient distribution of the fluid in the tank is uneven, which may easily cause the quality...
