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 for polyester production in a continuous or intermittent production device. The polycondensation reactor comprises a kettle body, wherein the upper part/top of the kettle body is provided with a gas-phase material outlet; the lower part/bottom of the kettle body is provided with a liquid-phase material outlet. The polycondensation reactor is characterized in that the upper part/top of the kettle body is further provided with a material inlet pipeline; a material distributor is horizontally arranged on the material inlet pipeline below an opening in the kettle body; one or more layers of guide plates are horizontally arranged below the material distributor. During working of the polycondensation reactor, a material is charged into the kettle body through the material inlet pipeline, uniformly distributed through the material distributor and uniformly distributed onto the guide plates, and flows downwards into the bottom of the kettle body from guide holes layer by layer. In the process, the material reacts and is evaporated and thickened gradually, and the kettle body can be heated through a jacket according to practical requirements, so that heat transfer in the reactor is improved, the reaction of the material is accelerated, and a condensation polymer of target viscosity is obtained more rapidly.

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 ...
