VOCS廢氣處理的七大技術

瀏覽次數: 發布日期:2018-12-30

關鍵詞:VOCS氣體凈化 VOCS廢氣處理

導讀:當前我國VOCS涉及的污染行業廣且各行業排放的VOCS種類繁多、成分復雜,常見的有烴類、醇類、醚類、酯類等。加油站、裝修、餐飲、干洗、噴涂、化工等生產或使用有機溶劑的行業都會產生VOCS排放,治理技術體系復雜,涉及十多種技術及組合技術,當前,VOCS廢氣處理技術主要包括熱破壞法、變壓吸附分離與凈化技術、吸附法和氧化處理方法等。

VOCS廢氣處理的七大技術

VOCS廢氣處理的七大技術

熱破壞法對于濃度較低的有機廢氣處理效果比較好,因此,在處理低濃度廢氣中得到了廣泛應用。這種方法主要分為兩種,即直接火焰燃燒和催化燃燒。直接火焰燃燒對有機廢氣的熱處理效率相對較高,一般情況下可達到99%。而催化燃燒指的是在催化床層的作用下,加快有機廢氣的化學反應速度。這種方法比直接燃燒用時更少,是高濃度、小流量有機廢氣凈化的首選技術。

二、吸附法
