摘要:	許多國內外文獻指出揮發性有機物 (Volatile Organic Compounds, VOCs)對環境和人體造成影響，然而國內許多產業類別的製程中都會產生VOCs，電力設備製造非固定污染源VOCs排放的最大宗，因應全球各地對能源需求的增長，可能推動市場發展，進而增加VOCs的產生。藉由實場調查及以往固定污染源空氣污染檢測報告瞭解電力設備製造業變壓器塗裝製程中空污排放現況，塗料之安全資料表瞭解物質種類成分，推估計算實場空氣污染防制設備沸石轉輪焚化系統處理VOCs排放量。本廠VOCs廢氣具高風量、低濃度，其中危害成分含量最高為二甲苯，經沸石濃縮可以轉換成低風量及高濃度的廢氣，二甲苯經沸石轉輪焚化系統處理後排放量推估為0.033 g/s低於排放標準，使用蓄熱式焚化爐能源回收效率達94%，減少液化石油天然氣之使用量。沸石轉輪整體來說可達90%以上之去除效率，蓄熱式焚化爐則高於94%以上，各產業的原物料、特性差異，所適用的最佳操作參數不同。選擇防制設備要考量製程及廠內塗料特性，才能發揮效能，希望做為未來廠內污染防制設備採購的參考依據。 ;Both internal and foreign literatures indicate that volatile organic compounds (VOCs) would affect human body and the environment. However, many of our internal industries produce VOCs during their productions. Especially in the process of painting transformer of electrical equipment manufacturing. Respond to the growth in energy demand all over the world, the VOCs may be increased when promoting the market upgrowth. Through the field research and the air pollution test reports in the past, we acknowledged the emissions status and material composition of the air pollution in the process of painting transformer of electrical equipment manufacturing. So that we can estimate the efficiency of processing VOCs by air pollution control devices - rotor concentrator thermal oxidizer system. The factory in this thesis has the exhaust gas with high air volume and low concentration. And the highest content of hazardous ingredients in the exhaust gas is Xylene. So we use the rotor concentrator to transform the exhaust gas to low air volume and high concentration. The emissions of Xylene after processing was estimated to be lower than the standard 0.033 g/s. The recycle rate of thermal oxidizer can reach 94% and reduce the usage of the liquefied petroleum gas. The total reducing rate of rotor concentrator is over 90% and for thermal oxidizer is 94%. But due to the reason that the hazard components and characteristics of the industry are different, the best operating parameters are different. When choosing the prevention equipment, we need to consider the production and the coating properties. So that the prevention can work with efficiency and becoming the reference in the future of purchasing the prevention equipment in the factory.
