阅读说明：本技术 用于将回收的材料混入聚酯熔体中的装置和方法 (Device and method for mixing recycled material into polyester melt ) 是由 亚历山大·帕瓦尔斯基 马丁·希托夫 海因里希·科赫 克里斯托弗·赫斯 于 2019-02-19 设计创作，主要内容包括：本发明涉及用于将用过的聚酯混入聚酯熔体中的装置和方法。该方法的一个特点是,在原始聚酯生产过程中,从中间阶段分出中间产物流,并在动态混合器中与回收的聚酯薄片混合,在该动态混合器中产生和/或提供不超过60％的熔融全部回收的聚酯薄片所需的熔融能量。将以此方式产生的混合物进料到中间阶段下游的后续阶段中,并随后在该过程中转化为所需的缩聚度。这样,可以物理地重新利用用过的聚酯或聚酯废料。(The invention relates to a device and a method for mixing used polyester into a polyester melt. A feature of the process is that during the original polyester production process, an intermediate product stream is taken from the intermediate stage and mixed with the recycled polyester flakes in a dynamic mixer where no more than 60% of the melting energy required to melt the entire recycled polyester flakes is generated and/or provided. The mixture produced in this way is fed to a subsequent stage downstream of the intermediate stage and is subsequently converted in the process to the desired degree of polycondensation. In this way, the used polyester or polyester waste can be physically reused.)
