| 項目名稱 | 採用化學洗滌有機廢氣淨化系統以減少塑膠噴漆工序揮發性有機化合物排放 | ||
| 示範項目類別 (技術主題) |
減少揮發性有機化合物（VOC）排放及處理技術，如活性碳吸附、催化燃料和生物過濾技術 | ||
| 簡介 | 將安裝採用化學洗滌的廢氣處理系統，以處理噴漆過程中收集的廢氣，以減少揮發性有機化合物排放。噴霧過程中含豐富有機物的氣體目前被排氣扇抽出並排放到戶外。為了提高揮發性有機化合物的去除效率，排出的空氣將被化學洗滌器處理。在洗滌室內，由於“類似溶解”效應可以吸收揮發性有機化合物的洗滌器溶液將從頂部噴灑。兩層小塑料球位於噴頭下方以增加揮發性有機化合物吸收的表面積。含揮發性有機化合物的廢氣將從下方進入化學洗滌室，與洗滌器溶液接觸，揮發性有機化合物將被吸收。然後排氣通過過濾層，其保留液體洗滌器溶液並釋放以打開空氣。洗滌器溶液將收集在下面的回收罐中，過濾然後重新用於洗滌。洗滌器溶液可重複使用幾個月，然後收集並轉讓給授權承包商進行進一步處理。 an exhaust air treatment system adopting chemical scrubbing will be installed to treat exhaust collected from paint spraying process to reduce VOC emissions. Organic-rich gas from spraying process is currently extracted by the exhaust fans and exhausted to the open air. To enhance VOC removal efficiency, the exhausted air will be treated by chemical scrubber. Inside the scrubber chamber, scrubber solution which can absorb VOC due to “like-dissolve-like” effect will be sprayed from the top. Two layers of small plastic balls were located below the sprinklers to increase surface area for VOC absorption. VOC-laden exhaust air will be driven into chemical scrubber chamber from below, comes into contact with the scrubber solution and VOC will be absorbed. The exhaust is then passed through a filter layer which retains liquid scrubber solution and released to open air. Scrubber solution will be collected in the recycling tank below, filtered then reused for scrubbing. The scrubber solution can be reused for few months, then collected and transferred to authorize contractor for further treatment. | ||
