技術簡介

傳統塑料乾燥系統僅使用單顆轉輪進行單段除濕，為達到某些產業(如:塑料射出成形)製程中所需之濕度需要使用極高的溫度(＞180℃)將除濕輪再生後再進行吸附，為製程用空氣除濕。本雙段式吸附轉輪塑料乾燥系統技術，透過將吸附段拆分成兩階段、使用兩顆轉輪進行吸附，可有效降低抵達極低濕度所需之再生溫度至60~80℃，此溫度範圍可更容易使用工廠之廢熱源或熱泵進行驅動，有效增加能源使用效率。本技術可應用於汙泥乾燥、塑料乾燥、食品乾燥與原物料乾燥等乾燥系統中、取代原有之單段乾燥系統，節能量約38~50％。

Abstract

Traditional plastic drying systems use a single desiccant wheel for one-stage dehumidification. To achieve the low humidity required in certain industries (e.g., plastic injection molding), extremely high temperatures (＞180°C) are needed to regenerate the desiccant wheel before adsorption can occur for air dehumidification in the process. The two-stage desiccant wheel plastic drying system technology divides the adsorption stage into two phases, utilizing two desiccant wheels for adsorption. This approach effectively reduces the regeneration temperature required to achieve ultra-low humidity to a range of 60–80°C. This temperature range allows for easier utilization of waste heat sources or heat pumps available in factories, significantly improving energy efficiency. This technology can be applied to drying systems for sludge, plastics, food, and raw materials, providing a replacement for traditional single-stage drying systems, with an energy efficiency increase of about 38~50％.

技術規格

取代傳統單段吸附式轉輪乾燥系統，其再生溫度可由＞140℃降低至60~80℃。

Technical Specification

Replacing traditional single-stage desiccant wheel drying systems, the regeneration temperature can be reduced from ＞140°C to 60–80°C, increasing the energy efficiency by about 50％.

技術特色

傳統塑料乾燥系統使用單顆轉輪單段除濕，需高溫(＞180℃)再生轉輪，因此只能使用電熱器(COP＜1)再生。本雙段吸附轉輪系統將吸附分為兩階段，使用兩顆轉輪，可降低再生溫度至60~80℃，更易利用廢熱或高效率熱泵(COP＞2)驅動，提升能源效率。適用極低濕乾燥領域。
