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.

催化燃燒工藝流程

Catalytic combustion process flow

有機(jī)廢氣進(jìn)入干式過濾器對顆粒物進(jìn)行凈化處理后，再進(jìn)入后部活性炭吸附箱中進(jìn)行廢氣的吸附濃縮處理，催化燃燒設(shè)備定期對活性炭吸附濃縮后的廢氣進(jìn)行高效催化處理，達(dá)標(biāo)后的潔凈氣體通過15米煙囪高空排放。

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.

當(dāng)活性炭箱吸附飽和之后，系統(tǒng)會自動對活性炭箱進(jìn)行脫附處理，吸附飽和后的活性炭利用熱空氣進(jìn)行脫附再生，脫附出的濃縮有機(jī)物被送往燃燒床通過與催化劑結(jié)合進(jìn)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.

在催化氧化爐內(nèi)被加熱到250～300℃的有機(jī)廢氣在貴金屬催化劑的作用下發(fā)生無焰燃燒，有機(jī)廢氣被氧化分解成二氧化碳和水，達(dá)到廢氣處理的目的，廢氣處理后的潔凈氣體經(jīng)煙囪達(dá)標(biāo)排放。燃燒后的熱空氣通過高效換熱器進(jìn)行降溫，降溫后的氣體部分排放，部分用于活性炭脫附再生以達(dá)到廢熱利用和節(jié)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.

廢氣處理設(shè)備有機(jī)廢氣的綜合凈化效率在97%左右，對于機(jī)械化工、汽車涂裝、家具建材、印刷、食品等行業(yè)排放的低濃度、多成分、無回收價值的廢氣均有較好的處理效果。

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.

設(shè)備與RTO設(shè)備相類似，采用床式設(shè)計(jì)，蓄熱室底部填充陶瓷蓄熱體，催化劑填充在陶瓷蓄熱體與氧化室之間。

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.

廢氣處理設(shè)備適用于連續(xù)性排放濃度較高的生產(chǎn)工藝廢氣處理，對于生產(chǎn)工藝中揮發(fā)的所有VOCS有機(jī)廢氣都可有效處理；RCO廢氣處理設(shè)備適用于間歇性的生產(chǎn)工況廢氣處理。另外需注意的是，腐蝕性廢氣在RTO、RCO中都不能處理。

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.
