Abstract
The utility model discloses a disk reactor for continuous polymerization of PBT (polybutylene terephthalate). The disk reactor comprises a double-axle driven reactor body (1), a low-viscosity axle (2) and a high-viscosity axle (3) are arranged at two ends of the double-axle driven reactor body (1), respectively, a material inlet (4) is arranged on the side with the low-viscosity axle (2) of the double-axle driven reactor body (1), a high-viscosity material outlet (5) is arranged on the side with the high-viscosity axle (3) of the double-axle driven reactor body (1), and a low-viscosity material outlet (6) is arranged on the double-axle driven reactor body (1) and between the material inlet (4) and the high-viscosity material outlet (5). Since the low-viscosity material outlet (6) is added between the material inlet and the high-viscosity material outlet of the double-axle driven PTB disk reactor, the viscosity of a material from the low-viscosity material outlet can be adjusted in a certain range without affecting the viscosity of a material from the high-viscosity material outlet, and thus the flexibility and economical performance of operation of the disk reactor for continuous polymerization of PBT can be improved greatly.
Description
Technical field
The utility model relates to a kind of device of producing low sticky PBT melt, specifically a kind of disk reactor for PBT continuous polymerization that two kinds of viscosity specification PBT melts can be provided simultaneously.
Background technology
Traditional PBT polymerization mainly adopts three poly-still technological processes of esterification → pre-polymerization → end, the most of selector disc reactor of terminal polymerization kettle, prepolymer (inherent viscosity 0.26dl/g) further carries out at terminal polymerization kettle the PBT melt that polycondensation reaction formation characteristic viscosity is 0.75～1.05dl/g.Make the section of PBT polyester through granulation, for modification, spinning, membrane and solid-phase tack producing.The weak point of this kind of disk reactor is the PBT melt that a kind of viscosity specification can only be provided.
Summary of the invention
The purpose of this utility model is the defect existing for existing disk reactor, and a kind of disk reactor for PBT continuous polymerization that two kinds of viscosity specification PBT melts can be provided is simultaneously provided.
The purpose of this utility model solves by the following technical programs:
A kind of disk reactor for PBT continuous polymerization, comprise Two axle drive reactor body, the two ends of Two axle drive reactor body are respectively equipped with low sticky axle and high sticky axle, the Two axle drive reactor body of low sticky axle one side is provided with charging aperture, the Two axle drive reactor body of high sticky axle one side is provided with high sticky material discharging opening, it is characterized in that the Two axle drive reactor body between described charging aperture and high sticky material discharging opening is provided with low sticky material discharging opening.
Described low sticky material discharging opening is positioned at the middle part of Two axle drive reactor body.
Distance between described low sticky material discharging opening and charging aperture is not more than the distance between low sticky material discharging opening and high sticky material discharging opening.
Described low sticky material discharging opening place is provided with plunger valve.
Described Two axle drive reactor body is provided with gaseous phase outlet, and gaseous phase outlet is positioned on the Two axle drive reactor body of high sticky material discharging opening one side.
The utility model has the following advantages compared to existing technology:
