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

Abstract

The invention relates to an energy-saving and high-efficiency self-cleaning polymerization process and device. The energy-saving and high-efficiency self-cleaning polymerization device comprises a shell and tube reactor and a rotor type self-cleaning strengthened heat transfer device, wherein the rotor type self-cleaning strengthened heat transfer device mainly comprises rotors, middle support frames, backwater end pendants, limit members and lifting hook pendants, and the middle support frames are used for strengthening the rigidity of a rotating shaft, improving a self-centering effect of the rotors and prolonging the operation service life of the whole device. A locating pin roll of each lifting hook pendant is matched with a locating hole of the adjacent lifting hook pendant so that the axial tension strength of the single lifting hook pendant is enhanced. Materials participating in the polymerization pass through a tube pass, and heating or cooling fluid passes through a shell pass. Reaction materials are fully mixed through the rotation of the rotors, and heat generated in the polymerization is rapidly released. The energy-saving and high-efficiency self-cleaning polymerization device also has a self-cleaning function; according to the energy-saving and high-efficiency self-cleaning polymerization device, the problem of adhering of a kettle is solved, the product quality and production efficiency are improved, and thus the defect of a traditional production mode is avoided.

Description

technical field [0001] The invention belongs to the field of polymerization production, and in particular relates to an energy-saving, high-efficiency, self-cleaning polymerization process and device. 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 she...

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
