活性炭吸附—催化燃烧脱附把两者的优点地结合起来。先利用活性炭进行吸附浓缩，当活性炭吸附接近饱和时，利用电加热启动催化燃烧设备，并利用热空气加热活性炭吸附床，当催化燃烧反应床加热到～250℃，活性炭吸附床局部达到60～100℃时，从吸附床解吸出来的高浓度废气就可以在催化反应床中进行低温氧化反应。反应后的高温气体经换热器换热，一部分回用送入活性炭吸附床进行脱附，另一部分排入大气。脱附出来的废气经换热器换热后温度提高，降低了催化燃烧的启动电功率，从而使催化燃烧装置及脱附过程达到小功率运行。

催化燃烧装置RCO，经过干式过滤器过滤后的废气进入放置有蜂窝状活性炭的吸附单元，经过使用一段时间后，其中的一个吸附单元的活性炭达到饱和，系统自动切换到备用单元，并将饱和的吸附单元关闭隔离，并启动吸附单元再生过程，将饱和的吸附单元活性炭里的有机废气脱附出来，并在催化剂的作用下燃烧并转化成二氧化碳及水蒸气，再生后的活性炭吸附单元作为备用床，等下个吸附床饱和后轮换，这样可保证系统的连续运行。

通过活性炭吸附，可将大风量低浓度的有机废气浓缩为小风量高浓度的废气，再进入RCO装置处理，可以节约运行成本。废气进行有效收集后，先进行预处理，再进入活性炭吸附装置，气体在活性炭床层保持一定的停留时间，气体中的VOCs被吸附在活性炭表面，洁净气体从活性炭床层排出后可以直接通过引风机排空，经过RCO处理后的洁净气体通过热交换到一定温度后作为脱附风，通过活性碳床进行脱附，从活性炭吸附装置脱附出来的浓缩有机物进入RCO装置后通过贵金属催化剂燃烧分解，分解温度在200-250°℃，有机废气被分解成二氧化碳和水，以此循环，待废气脱附分解完成后排入烟筒后达标排放。

性炭催化燃烧设备是目前处理有机废气的热门设备，对废气进行吸附、脱附、燃烧分解成CO2和H2O，处理效率高达95%以上，多种型号选择符合用户需求，帮助用户达标排放。这款设备是活性炭吸附箱与蓄热式催化燃烧设备的组合工艺，具有起燃温度低、能耗小的特点。

化燃烧设备-喷漆房废气处理，喷漆房RCO催化燃烧工业废气处理，RCO催化燃烧工业废气处理，废气的吸附和浓缩主要利用活性炭的吸附。这套设备由几套活性炭吸附箱组成。在系统运行过程中，打开一套活性炭吸附箱，对工业废气进行吸附和浓缩。一组活性炭饱和后，打开二组活性炭吸附箱，进行与一组活性炭吸附箱相似的吸附过程。当二组活性炭吸附箱时，组活性炭吸附箱脱附。以此类推，这套系统中的活性炭吸附箱循环进行吸附和解吸过程。解吸后的工业废气进入催化燃烧设备，被氧化分解成无害的小分子化合物，达标排放。
