Energy-saving and high-efficiency self-cleaning polymerization process

Abstract

The invention relates to an energy-saving and high-efficiency self-cleaning polymerization process which is characterized in that a shell and tube reactor is adopted as a polymerization device, and a rotor type strengthened heat transfer and self-cleaning device is arranged in a tube pass of the shell and tube reactor; when a material participating the polymerization enters the tube pass, a rotor rotates in a tube pass reaction liquid by depending on a suspension mechanism, the probability that the tube pass fluid attaches to the tube wall is reduced by depending on high flowing speed in a gap between the tube wall and the rotor and a spiral pushing action of a rotor blade to the tube pass fluid, the phenomenon that attachment on the tube wall is avoided; reaction fluids of different viscosities can be in large-area mutual contact by depending on a shearing and crushing action of the rotor blade to the reaction fluid, mass transfer between the reaction fluids of different viscosities is frequent and easy by depending on the turbulent flow of the blade, the polymerization is thorough, the function of a stirring rod in chemical reaction is realized, and the reaction rate is greatly increased.

Description

technical field [0001] The invention relates to a polymerization production process, in particular to an energy-saving, high-efficiency, self-cleaning polymerization process. Background technique [0002] All kinds of polymer material products appear in modern life, including rubber, plastic, fiber, coating, adhesive and polymer-based composite materials, etc. One method usually used in the production of polymer materials is polymerization reaction, such as plastic (PVC), polyester fiber, etc. are prepared by polymerization reaction. [0003] In the process of polymerization reaction, the problem of sticking to the kettle has always been a major obstacle restricting the development of polymerization reaction. In the polymerization reaction of any process, as long as the monomer contacts (such as the inner wall of the reaction vessel, stirring equipment, other parts of the polymerization vessel), the deposition or adhesion of polymer plasticized sheets will inevitably occur ...

AI Technical Summary

Problems solved by technology

[0008] 1. The adhesion fastness of the anti-adhesive coating is low, it is easy to mix into the product, reduce the purity of the product, and affect the effect of the anti-adhesive agent

[0009] 2. Insufficient anti-oxidation time will cause the anti-sticking agent to fail early, resulting in a decline in product quality

[0010] 3. The problem of color cast, the coating will be eroded and dropped into the kettle during the polymerization reaction, and the dark anti-sticking kettle agent may contaminate the resin (such as "American red", "British blue"), which may contaminate the resin Make the resin reddish or bluish, affecting the color of the product

[0011] 4. It is difficult to operate when using, and manual spraying is required, and the uniformity and integrity of the spraying cannot be guaranteed
