The waste gas treatment equipment (catalytic combustion equipment) filters organic waste gas through high-efficiency filters and enters the honeycomb activated carbon adsorption module for adsorption and concentration. With the help of a catalyst, VOCs organic waste gas undergoes flameless combustion at a lower ignition temperature (280-500 ℃), oxidizes and decomposes into carbon dioxide and water, thereby achieving the purpose of waste gas treatment.

催化燃烧工艺流程

Catalytic combustion process flow

有机废气进入干式过滤器对颗粒物进行净化处理后，再进入后部活性炭吸附箱中进行废气的吸附浓缩处理，催化燃烧设备定期对活性炭吸附浓缩后的废气进行高效催化处理，达标后的洁净气体通过15米烟囱高空排放。

The organic waste gas enters the dry filter to purify the particulate matter, and then enters the rear activated carbon adsorption box for adsorption and concentration of the waste gas. The catalytic combustion equipment regularly performs efficient catalytic treatment on the waste gas after adsorption and concentration of activated carbon, and the clean gas that meets the standard is discharged at a height of 15 meters through a chimney.

当活性炭箱吸附饱和之后，系统会自动对活性炭箱进行脱附处理，吸附饱和后的活性炭利用热空气进行脱附再生，脱附出的浓缩有机物被送往燃烧床通过与催化剂结合进行催化分解。

After the activated carbon box is saturated with adsorption, the system will automatically perform desorption treatment on the activated carbon box. The saturated activated carbon is desorbed and regenerated using hot air, and the desorbed concentrated organic matter is sent to the combustion bed for catalytic decomposition by combining with the catalyst.

在催化氧化炉内被加热到250～300℃的有机废气在贵金属催化剂的作用下发生无焰燃烧，有机废气被氧化分解成二氧化碳和水，达到废气处理的目的，废气处理后的洁净气体经烟囱达标排放。燃烧后的热空气通过高效换热器进行降温，降温后的气体部分排放，部分用于活性炭脱附再生以达到废热利用和节能的目的。

The organic waste gas heated to 250-300 ℃ in the catalytic oxidation furnace undergoes flameless combustion under the action of precious metal catalysts. The organic waste gas is oxidized and decomposed into carbon dioxide and water, achieving the purpose of waste gas treatment. The clean gas after waste gas treatment is discharged through the chimney to meet the standards. The hot air after combustion is cooled by an efficient heat exchanger, and some of the cooled gas is discharged, which is used for activated carbon desorption and regeneration to achieve waste heat utilization and energy conservation.

废气处理设备有机废气的综合净化效率在97%左右，对于机械化工、汽车涂装、家具建材、印刷、食品等行业排放的低浓度、多成分、无回收价值的废气均有较好的处理效果。

The comprehensive purification efficiency of organic waste gas from waste gas treatment equipment is around 97%, and it has good treatment effects for low concentration, multi-component, and non recyclable waste gas emitted by industries such as mechanical engineering, automotive painting, furniture and building materials, printing, and food.

设备与RTO设备相类似，采用床式设计，蓄热室底部填充陶瓷蓄热体，催化剂填充在陶瓷蓄热体与氧化室之间。

The equipment is similar to RTO equipment and adopts a bed design. The bottom of the regenerator is filled with ceramic heat storage material, and the catalyst is filled between the ceramic heat storage material and the oxidation chamber.

废气处理设备适用于连续性排放浓度较高的生产工艺废气处理，对于生产工艺中挥发的所有VOCS有机废气都可有效处理；RCO废气处理设备适用于间歇性的生产工况废气处理。另外需注意的是，腐蚀性废气在RTO、RCO中都不能处理。

The waste gas treatment equipment is suitable for continuous production process waste gas treatment with high emission concentration, and can effectively treat all volatile VOCS organic waste gases in the production process; RCO waste gas treatment equipment is suitable for intermittent production conditions. Additionally, it should be noted that corrosive waste gas cannot be treated in RTO or RCO.
