以靜電集塵裝置結合光催化反應之空氣清淨模組處理廢油煙氣中之油煙及氣相有機物
| 中文摘要 | 本計畫擬採用靜電集塵裝置有效處理廢油煙氣中油滴之特性，進一步結合該紫外光/光觸媒程序，以去除餐飲業廢氣中氣相有機物所衍生的異味。本研究首先以TiO2溶膠以及經金屬改質(Pt、Pd、Ag、Ni、Fe、Co)後之TiO2作為該程序之光觸媒，並以甲苯及二甲基硫進行觸媒光催化活性測試，選取較高光觸媒催化活性之觸媒製備二氧化鈦空氣淨化濾材；本計畫在考量觸媒之光催化活性以及製備成本後，製備純TiO2以及Ag-TiO2濾材，組裝進本研究所設計之光觸媒空氣淨化裝置，進行兩個月的實地測試，並以火焰離子化偵測器及GC-MS分析油煙內各物種被光催化降解之情況。在經過長期測試後可發現，以光波長185及254 nm之混合燈具作為光觸媒濾材模組之光源時，可以在含有氧氣的環境下產生臭氧來降解VOCs，因此可使本連續式的反應達到約32 %的礦化效率。若將本計畫所製備Ag-TiO2濾材組裝進本研究所設計之光觸媒空氣淨化裝置進行實地測試，可發現餐飲業廢氣之礦化效果可提昇至約42 %，足以證明本發明具有有效去除餐飲業尾氣中異味之能力。 | ||

Application of Air Purification Module with Electrostatic Precipitator and Photocatalytic System for
| 英文摘要 | In this project, the air purification module with the combination of electrostatic precipitator and photocatalytic system was developed to simultaneously remove the oil droplet, dust, and odor molecules (VOCs) from the restaurant discharges. The metal-deposited TiO2 (Pt-TiO2, Pd-TiO2, Ag-TiO2, Ni-TiO2, Fe-TiO2, Co-TiO2) were prepared by the photodeposition process. The photocatalytic activity of the metal-deposited TiO2 was determined based on the photocatalytic decompositions of toluene and dimethyl sulfide. Based on the preparation cost and the photocatalytic activity of photocatalyst, TiO¬2 and Ag-TiO was applied for the photocatalytic system of the air purification module to carry out the long-term performance test at the restaurant discharge of NTUST. The mineralization of VOCs and the species of the inlet and outlet gas streams were measured by a flame ionization detector and the GC-MS. The test results showed that approximately 32% of VOCs was converted to CO2 and water in the air purification module with the 185 and 254 nm combined UV light possibly because of the ozone generation in the presence of oxygen. Almost 42% of VOCs mineralization was achieved by the air purification module with Ag-TiO2 and the 185 and 254 nm combined UV light sources. The air purification module developed by this project is adequately applied to the equipment for cleaning restaurant discharge. | ||
