Abstract

PROBLEM TO BE SOLVED: To separate and remove crystal objects generated in recycling by thermolysis of PET products, in which ethylene glycol is reused as fuel and terephthalic acid is reused as a material of a PET bottle, by collecting ethylene glycol and terephthalic acid by performing thermolysis of a PET composite product which is especially difficult in recycling of plastics.SOLUTION: When decomposition gas passes through a temperature zone where crystals of terephthalic acid are generated, a circulation cooling function of thermolysis equipment is utilized for managing and operating so that the crystals do not adhere to piping.

Description

発明の詳細な説明Detailed Description of the Invention

本発明はＰＥＴ製品のリサイクルに関するものである。The present invention relates to the recycling of PET products.

加熱分解するリサイクル技術では発生する結晶の分離回収が出来ず、特にＰＥＴの複合製品（例えばＰＥＴのシートにＰＥのシートを張り合わせ軽量化を図りながら製品の強度を強化するもの）が増えている状況下で現在リサイクル技術がなく焼却か埋立されている状況で本件の機器の発明は極めて需要の高いものです。Recycling technology that decomposes by heat does not allow the separation and recovery of crystals that are generated, and in particular, there is an increase in PET composite products (for example, those that strengthen the strength of a product while reducing the weight by attaching a PE sheet to a PET sheet) There is no recycling technology below, and the invention of this equipment is extremely in demand in the situation where it is incinerated or landfilled.

発明が解決しようとする課題Problems to be solved by the invention

本発明はＰＥＴ製品の加熱分解によるリサイクルの際発生する結晶を分離除去する機器の製作。The present invention is a device for separating and removing crystals generated during recycling of PET products by thermal decomposition.

問題を解決するための手段Means to solve the problem

当社の加熱分解によるリサイクル設備の循環冷却装置の既に特許を申請している機能を生かしては発生する結晶を除去しやすい状態で捕捉し分離回収する。Taking advantage of our patented function of the circulating cooling device for recycling equipment by thermal decomposition, the generated crystals are captured and separated and recovered in an easy-to-remove state.
