Polymer reactor with novel structure

Abstract

The invention relates to a polymer reactor with a novel structure, comprising a barrel body which is provided with a heat transfer medium inlet and a heat transfer medium outlet, wherein a first tube plate, a second tube plate and a core body positioned between the first tube plate and the second tube plate are arranged in the barrel body; two ends of the core body are respectively supported on the first tube plate and the second tube plate and respectively designed into a nozzle structure, and through holes are arranged on the lateral wall of each nozzle; a plurality of spiral tubes which are sleeved inside and outside and formed by reeling hollow tubes are arranged outside the core body, wherein the rotation directions of hollow tubes of the spiral tubes which are adjacent inside and outside are opposite, one end of the hollow tube of each spiral tube passes through the first tube plate and is then communicated with the heat transfer medium outlet, and the other end of the hollow tube of each spiral tube passes through the second tube plate and is then communicated with the heat transfer medium inlet; the inner end of a first connecting tube is communicated with a nozzle at one end of the core body so as to enable the outer end to be used as a material inlet end; and the inner end of a second connecting tube is communicated with a nozzle at the other end of the core body so as to enable the outer end to be used as a material outlet end. The invention provides the polymer reactor which has small energy consumption as well as full and even heat exchange, can prevent materials from backmixing on the flow direction and realize the temperature region segmentation.

Description

technical field [0001] The invention relates to a polymerization reactor used in the chemical industry, in particular to a polymerization reactor suitable for polymerization reactions of various high molecular polymers, especially solution polymerization reactions and bulk polymerization reactions. Background technique [0002] Polymerization reactors can be divided into suspension polymerization (including slurry polymerization) reactors, emulsion polymerization reactors, solution polymerization reactors and bulk polymerization (including polycondensation) reactors according to the polymerization method. According to the structure of the polymerization reactor, it is divided into stirred tank reactor, tubular or tower reactor and fluidized bed reactor. Different structural types and different polymerization reaction methods of polymerization reactors determine the characteristics of the whole group of polymerization reactors, and ultimately determine the polymerization prod...

AI Technical Summary

Problems solved by technology

However, this kind of polymerization reactor has the following disadvantages: large power consumption; the flow rate of the material at the center and the edge is different, and the reaction time of each particle of the material is different; the heat removal is uneven during the polymerization process, and the difference between the center and the edge Larger; the heating and cooling of the polymerization reaction are not smooth, and there are also certain back-mixing defects

However, there are still various problems, such as, the effect of static mixing and heat removal, the effect of heating is not fully combined, the material is uneven, the polymer sticks to the wall, etc.,

[0005] At the same time, none of the current polymerization reactors can achieve the division of temperature zones
