根據統計資料，在各種空氣污染物排放總量中，以移動污染源中車輛排放的廢氣最為嚴重，其中柴油車所排出之粒狀污染物，為影響空氣品質主要污染來源之一。為管制本縣柴油引擎為主之移動性污染源，降低其污染排放量，以減少空氣污染對縣民造成之健康危害，花蓮縣環境保護局於本年度執行「花蓮縣垃圾車裝置濾煙器示範運行計畫」，執行濾煙器安裝實車運行，以提升本縣空氣品質。 由本計畫執行之垃圾車加裝濾煙器運行檢測數據進行分析，並綜合本計畫執行成果及實際經驗，為能讓本縣柴油車排煙管制更具成效，提供適當建議，作為未來訂定管制策略之參考。 目前本計畫之成果摘要如下： (一)教育訓練 今年度本公司已完成2場次教育訓練作業；於108年04月16日(二)及10月25日(五)下午14：30~17：00假花蓮市公所清潔隊(花蓮縣花蓮市博愛街10-4號)辦理，邀請出席人員為花蓮市公所清潔隊班長、分隊長及駕駛司機等。 (二)問卷調查 問卷調查工作應每季執行一次，本階段共於108年1月、4月、7月、10月完成4次問卷調查作業，並回收問卷份數共計80份。 綜合前述問卷的結果，顯示在本階段統計期間，以第1次問卷調查之整體評價較差，第4次問卷調查之整體評價最佳；在4次問卷結果顯示，整體評價似與團隊服務滿意度 (問3)相關，於滿意度100%之第2、4次，整體之表現較好，表示可能除了系統穩定度之印象外，使用者遭遇故障或需協助時團隊之服務品質及速度，多少左右其整體評價。 (三)示範運行操作狀況 本計畫示範運行之20組濾煙器系統，發生之問題，多在系統安裝及原始設計之不精細，導致雖然大多是小地方的問題，但產生對使用者及管理者之困擾卻相當巨大；而問題主要為上述零件(點火針、噴油嘴、感溫棒)故障率高，造成系統無法順利再生，且後續衍生後續其他部份之故障(如濾心破損等)，本階段示範運行期間，噴油嘴之故障頻率為最高，而點火針及感溫棒故障雖略有改善，但仍持續發生，本團隊雖持續努力，但目前原廠仍無法提供完整有效之解決方案，尤以噴油嘴問題最大，系統穩定性仍需改善。 (四)場站檢測 階段工作共進行2次場站檢測，分別於108年1月及7月執行，雖有部分車輛場站檢測數值較高，如108年1月883-BH及108年7月750-BH、125-SM之0.6 m-1，但所有檢測結果，皆符合0.6 m-1 之標準。 (五)馬力比分析 依本計畫20輛安裝濾煙器之馬力比數據分析如表5.5-1。根據表5.5-1之統計，本階段示範運行期間檢測馬力比與基礎值差異最大為6%，最小為0%(無差異)，顯示大部分車輛安裝濾煙器前後之馬力比差異不大。 馬力比之差異統計，40輛次中，有3輛次馬力比無差異(占7.5%)、8輛次馬力比差±1%(占20%)、8輛次馬力比差±2%(占20%)、7輛次馬力比差±3%(占17.5%)、9輛次馬力比差±4%(占22.5%)、4輛次馬力比差±5%(占10%)、1輛次馬力比差±6%(占2.5%)。 (六)去除效率分析 1. 本計畫20輛濾煙器車輛之不透光率檢測數據彙整如表5.6-1，40輛次濾煙器車輛之黑煙去除率平均為91.5%。基礎值測定之不透光率最大值為2.9 m-1、最小值為1.0 m-1、平均值為1.5 m-1；本階段定期檢測不透光率最大值為0.3 m-1、最小值為0.0 m-1、平均值為0.12 m-1。 2. 本階段20輛安裝濾煙器之車輛，本階段定期之黑煙去除率平均為91.5%，其中有6輛平均去除率為100%，平均去除率介於99%~90%者共6輛，介於89%~80%者共7輛，介於79%~70%者共1輛；整體黑煙去除率效果仍維持9成以上。 (七)減量效益評估：彙總而言，本計畫目前估算之PM10削減量為158.0(kg/年)、PM2.5削減量為138.9(kg/年)。

According to statistical data, among the total emissions of various air pollutants, the exhaust emissions of vehicles from mobile pollution sources are the most serious. Among them, particulate pollutants emitted by diesel vehicles are one of the main sources of pollution that affect air quality. In order to control the mobile pollution source mainly based on diesel engines in this county and reduce its pollution emissions, in order to reduce the health hazards caused by air pollution to the county residents, the Hualien County Environmental Protection Bureau implemented the "Hualian County Garbage Truck Installation Smoke Filter Demonstration Operation" this year. "Plan", the implementation of smoke filters installed in real vehicles to improve the county's air quality. The operation data of the garbage trucks installed with smoke filters implemented by this plan will be analyzed, and the implementation results and practical experience of this plan will be integrated to provide appropriate suggestions for the county ’s diesel vehicle smoke control. References to fixed control strategies. The current achievements of this project are summarized as follows: (1) Education and training This year, the company has completed 2 educational training operations; on April 16 (Tue) and October 25 (Fri), 108: 108 to 17:00, the cleaning team of the fake Hualien City Office (Bolian, Hualien City, Hualien County) No. 10-4 Street), and invite the attendees to be the squad leader, squad leader and driver of the cleaning team of Hualien City Office. (2) Questionnaire survey The questionnaire survey should be carried out quarterly. In this stage, a total of 4 questionnaire surveys were completed in January, April, July, and October of 108 years, and a total of 80 questionnaires were recovered. Based on the results of the aforementioned questionnaires, during the statistical period of this stage, the overall evaluation of the first questionnaire survey was poor, and the overall evaluation of the fourth questionnaire survey was the best; the results of the four questionnaire surveys showed that the overall evaluation seemed to be consistent with team service satisfaction (Question 3) Relevant, in the second and fourth times of 100% satisfaction, the overall performance is better, indicating that in addition to the impression of system stability, the service quality and speed of the team when the user encounters a failure or needs assistance, how much The overall evaluation. (3) Demonstration operation status The 20 groups of smoke filter systems in the demonstration operation of this project are mostly caused by imprecise system installation and original design. Although most of the problems are in small places, the problems for users and managers are very huge. The problem is mainly due to the high failure rate of the above parts (ignition needle, fuel injection nozzle, temperature sensor), causing the system to fail to regenerate smoothly, and subsequent subsequent failures of other parts (such as filter damage, etc.), the demonstration operation at this stage During this period, the fault frequency of the fuel injection nozzle was the highest, and the faults of the ignition needle and the temperature sensing rod improved slightly, but they still continue to occur. Although the team continues to work hard, the original factory still cannot provide a complete and effective solution, especially The problem with the fuel injection nozzle is the biggest, and the system stability still needs to be improved. (4) Field station detection During the phase work, a total of 2 station inspections were carried out, which were carried out in January and July 108 respectively. Although some vehicles have higher station inspection values, such as January 108, 883-BH and July 750-BH, 125 -0.6 m-1 of SM, but all test results are in line with 0.6 m-1 standard. (5) Horsepower ratio analysis According to this plan, the horsepower ratio data analysis of 20 cigarette filters installed is shown in Table 5.5-1. According to the statistics in Table 5.5-1, the difference between the detected horsepower ratio and the basic value during the demonstration operation at this stage is a maximum of 6% and a minimum of 0% (no difference), showing that the difference in horsepower ratio before and after the installation of smoke filters in most vehicles is not large. Statistics of the difference in horsepower ratio show that among 40 vehicles, 3 have no difference in horsepower ratio (7.5%), 8 have less than 1% horsepower ratio (20%), and 8 have less than 2% horsepower ratio ( (Accounting for 20%), 7 vehicles with a horsepower ratio of ± 3% (17.5%), 9 vehicles with a horsepower ratio of ± 4% (22.5%), 4 vehicles with a horsepower ratio of ± 5% (10%), The ratio of one horsepower horsepower is ± 6% (accounting for 2.5%). (6) Analysis of removal efficiency 1. The opacity test data of 20 smoke filter vehicles in this project is summarized in Table 5.6-1, and the average black smoke removal rate of 40 smoke filter vehicles is 91.5%. The maximum value of the opacity of the basic value measurement is 2.9 m-1, the minimum value is 1.0 m-1, and the average value is 1.5 m-1; the maximum value of the opacity is periodically detected at this stage is 0.3 m-1, the minimum value It is 0.0 m-1, and the average value is 0.12 m-1. 2. At this stage, 20 vehicles equipped with smoke filters have an average black smoke removal rate of 91.5% at this stage, of which 6 vehicles have an average removal rate of 100%, and the average removal rate is between 99% and 90%. There are 7 vehicles ranging from 89% to 80% and 1 vehicle ranging from 79% to 70%; the overall effect of black smoke removal rate remains above 90%. (VII) Assessment of reduction benefit: In summary, the current estimated PM10 reduction in this plan is 158.0 (kg / year) and PM2.5 reduction is 138.9 (kg / year).
