Three-component polymeric monomer feeding device

Abstract

The invention discloses a three-component polymeric monomer feeding device and belongs to chemical industrial equipment, in particular to equipment for firstly mixing two components and then mixing the mixture and a third monomer to perform the polymerization reaction. The three-component polymeric monomer feeding device is characterized by consisting of an outer sleeve and a charging spray pipe arranged in the outer sleeve, wherein the charging spray pipe consists of an inner pipe and an outer pipe which are concentric; the front end of the inner pipe is sealed; small holes are uniformly distributed on the pipe wall of the inner pipe, which is close to the front end; a guider is arranged at the front end of an annular space between the outer pipe and the inner pipe; an annular space between the outer sleeve and the outer sleeve is used as a third component flow channel; the annular space between the outer pipe and the inner pipe is used as a second component flow channel; and the inside of the inner pipe is used as a first component flow channel. According to the device, the first two materials can be sufficiently mixed, which is beneficial to performing the reaction; a generated catalyst is immediately sprayed out by a nozzle and is mixed with the monomer to perform the polymerization reaction without remaining nearly, and at the time, the catalyst has the highest activity and is beneficial to the polymerization reaction; and the polymerization reaction is easy to control.

Description

technical field [0001] The present invention belongs to chemical industrial equipment, especially the equipment in which two components are firstly mixed and then mixed with a third monomer to undergo polymerization reaction. Background technique [0002] Polymerization reactions, such as polyisobutylene cationic polymerization reactions, use liquid catalysts in many cases. The liquid catalysts are composed of two or more liquid materials. The conventional method is: first use a set of equipment to mix the two components that make up the catalyst, A complex reaction occurs to form a complex. This type of reaction is very fast. The generated catalyst is then transported to the liquid pipeline of the third material (monomer) through the pipeline, and the complex is mixed with the third monomer to polymerize. reaction. The main problem of this conventional three-material polymerization method is to build another two-component mixing reaction device, and the mixed-reacted mater...
