Embodiment 1

[0034] This embodiment provides a kind of reaction device, is used for the reaction of polymer, as figure 1 shown, including,

[0035] The tower body 1 is a cylinder with accommodating space;

[0036] The stirring device includes a rotating shaft 21 arranged vertically at the central position of the tower body 1 and driven by a power device to rotate, and an axial interval along the vertical direction of the rotating shaft 21 is arranged on the rotating shaft 21 Several paddles 22 on the

[0037] The rotating shaft 21 is hollow to form an air channel 31, and the paddle 22 is formed with a main channel 32 arranged axially along the paddle 22, and a side channel 33 arranged at a certain angle with the main channel 32, so The main channel 32 communicates with the air channel 31, and extends toward the axial direction of the paddle 22 to form a main air injection port, and the side channel 33 communicates with the main channel 32 and extends toward the diameter of the paddle 22....

Abstract

The invention relates to a reaction device, which integrates a stirring device and a steam feeding mechanism, and forms a high-temperature steam circulation channel on the rotating shaft and paddle of the stirring device, and the high-temperature steam is ejected from the gas injection port on the paddle. The paddles and multiple air jets are located inside the tower body. On the one hand, they can disperse the steam, promote the liquefaction of the steam in the tower body, and fully release the heat carried by the steam into the tower body. After the steam is liquefied, it forms a polymer Soft water for polymer production raw materials. In addition, the paddles and air jets can also follow the rotation of the shaft, so that the steam can reach all parts of the tower body more evenly, which improves the stirring effect of high-temperature steam on the high-molecular polymer raw materials in the tower body. The reaction of the molecular polymer is more sufficient and uniform, the content of unreacted polymerized monomer is low, and the molecular weight of the high molecular polymer is relatively uniform.

Description

technical field [0001] The invention relates to a reaction device, which belongs to the technical field of chemical equipment. Background technique [0002] The polymer polymerization reaction is to add the raw materials of the reactants into the reaction vessel, and control the reaction conditions to polymerize the reaction monomers to form a polymer. In order to make the reaction proceed uniformly, it is necessary to stir the reactants in the reaction vessel. At present, mechanical stirring is often used to stir the reactants. [0003] Chinese patent document CN202778444U discloses a reaction vessel heated and stirred by steam, which includes a tower body and a pipe inserted into the tower body, and the pipe has a steam inlet. In specific use, high-pressure steam enters the tower body through the pipe and the steam inlet provided on the pipe to stir the liquid mixture in the tower body. However, since the high-pressure steam directly enters the tower body through the pi...
