吸附+催化燃燒裝置

采用(yong)吸附濃縮+催化(hua)燃燒組合工藝(yi)，整個系統實現了凈(jing)(jing)化(hua)、脫附過(guo)程閉循環，與回(hui)收類(lei)有機廢(fei)氣凈(jing)(jing)化(hua)裝(zhuang)置相比，無須(xu)備(bei)(bei)壓縮空氣和蒸氣等附加(jia)能(neng)源，也(ye)無須(xu)配(pei)備(bei)(bei)冷卻塔等附加(jia)設備(bei)(bei)，運行過(guo)程不產生二(er)次污染，設備(bei)(bei)投(tou)資及運行費(fei)用(yong)低。

選用特殊成型(xing)的蜂(feng)窩活(huo)性炭作為(wei)吸附材料(liao)，吸附劑壽命長，吸附系統阻(zu)力低，凈化效率高(gao)。

用(yong)貴金屬鈀、鉑載在(zai)蜂窩陶瓷上作催(cui)化(hua)劑(ji)，催(cui)化(hua)燃燒率達97%以上，催(cui)化(hua)劑(ji)壽命長、催(cui)化(hua)劑(ji)的分解溫(wen)度低，脫(tuo)附預熱時間(jian)短(duan)，能耗低。
