Embodiment Construction

[0025] The present invention will be further described below in conjunction with the accompanying drawings.

[0026] The present invention relates to a polycondensation reactor used in a continuous or batch production plant for polyester production, Figure 1 to Figure 5 It is shown as an embodiment, including a kettle body 1 , a jacket 4 , a material inlet pipe 5 , a liquid phase material outlet 6 and a gas phase material outlet 7 . The jacket is located outside the outer surface of the kettle body 1, the jacket is preferably a double-layer jacket, and the kettle body is provided with an inlet and an outlet of a heating medium communicated with the inner cavity of the jacket ( Not shown in the figure), through the inlet and outlet of the heating medium, the heating medium can be passed into the inner cavity of the jacket to increase the temperature in the kettle body and improve the heat transfer in the reactor. The inlet of the material inlet pipeline is located at the uppe...

Abstract

The invention relates to a polycondensation reactor used in a continuous or batch production device for polyester production. The liquid phase material outlet is characterized in that the upper part / top of the kettle body is also provided with a material inlet pipe, and the material inlet pipe is horizontally provided with a material distributor below the opening in the kettle body, and the material distributor is below the material distributor. One or more layers of deflectors are arranged horizontally. When the present invention works, the material enters the kettle body through the material inlet pipe, and the material is evenly distributed by the material distributor, so that the material is evenly distributed on the guide plate, and the material flows downward layer by layer from the guide hole to the bottom of the kettle body. The material in the reactor reacts and evaporates, and the material gradually becomes thicker. During the process, the kettle body can be heated through the jacket according to actual needs, so as to improve the heat transfer in the reactor, speed up the reaction of the material, and obtain the polycondensation of the target viscosity more quickly. things.

Description

technical field [0001] The invention relates to a polycondensation reactor used in a continuous or batch production plant for polyester production. Background technique [0002] In the existing polyester production, according to different main processes, generally 1-3 polycondensation reactors are set up. Most polycondensation reactors use disc-type, frame-type, and squirrel-cage stirrers, which need to be driven by an external motor, resulting in complex reactor structures and high energy consumption. Contents of the invention [0003] In order to overcome the above-mentioned defects under the prior art, the object of the present invention is to provide a kind of polycondensation reactor used in the continuous or batch production device of polyester production, this reactor does not need motor drive, thereby makes polyester production process simple It is suitable for polyester production, especially for viscoelastic polymer production. [0004] Technical scheme of the ...
