一、吸附-催化燃烧法原理 ：
吸附浓缩-催化燃烧法，该设备采用多气路连续工作，设备多个吸附床可交替使用。含有机物的废气经风机的作用，经过活性炭吸附层，有机物质被活性炭特有的作用力截留在其内部，吸附去处效率达80%，吸附后的洁净气体排出；经过一段时间后，活性炭达到饱和状态时，停止吸附，此时有机物已被浓缩在活性炭内，之后按照PLC自动控制程序将饱和的活性炭床与脱附后待用的活性炭床进行交替切换。CO（催化氧化设备）自动升温将热空气通过风机送入活性炭床使碳层升温将有机物从活性炭中“蒸”出，脱附出来的废气属于高浓度、小风量、高温度的有机废气。 催化燃烧法：VOC-CH 型有机气体催化净化装置，是利用催化剂使有害气体中的可燃组分在较低的温度下氧化分解的净化方法。对于 CnHm 和有机溶剂蒸汽氧化分解生成CO2和H2O并释放出大量热量。其反应方程式为：
1. Principle of adsorption and catalytic combustion
Adsorption concentration - catalytic combustion method, the equipment USES the multi - gas road continuous work, the equipment multiple adsorption bed can be used alternately.Containing organic exhaust gas under the effect of fan, after activated carbon adsorption layer, organic matter was activated carbon special forces trapped in its internal, adsorption for efficiency up to 80%, after the adsorption of clean gas discharge;After a period of time, activated carbon saturated state, stop the adsorption, the organic matter has been concentrated in the activated carbon, then according to the PLC automatic control program will be saturated activated carbon bed and take off the attached treated with activated carbon bed for alternating switch.CO catalytic oxidation equipment) will automatically warming hot air through the fan into activated carbon bed warming carbon layer to "evaporate" from activated carbon in the organic matter, stripping out the exhaust gas belongs to, small volume, high temperature, high concentration organic waste gases.Catalytic combustion method: VOC-CH - type organic gas catalytic purification device is a purification method which USES the catalyst to oxidize the combustible components in harmful gases at lower temperature.For CnHm and organic solvent vapor oxidation decomposition to generate CO2 and H2O and release a lot of heat.Its reaction equation is:

有机物利用自身氧化燃烧释放出的热量维持自燃，如果脱附废气浓度足够高，CO 正常使用需要很少的电功率甚至不需要电功率加热，做到真正的节能环保，同时，整套装置安全、可靠、无任何二次污染。
Activated carbon stripping out, small volume, high temperature, high concentration organic waste gases after fire filter filter into the special plate heat exchanger, and catalytic reaction after high temperature gas for energy exchange indirectly, when the temperature of the exhaust gas source get promotion for the first time;The gas with a certain temperature goes into the preheater for the second temperature rise.After entering the first level catalytic reaction, organic waste gases at the bottom of the low temperature decomposition, and release energy, to direct heat of exhaust gas source, to increase the temperature of the gas to the best temperature catalytic reaction;Through temperature detection system, the temperature is in accordance with the temperature requirements of the catalytic reaction, and it enters the catalytic combustion chamber, and the organic gas is decomposed completely, releasing a large amount of heat.After purification, the gas is converted by the heat exchanger to the cooling air flow, and the cooled gas is drained by the induced fan.
Organic matter using its oxidation maintain spontaneous combustion heat release, if the stripping waste gas concentration is high enough, CO in normal use requires little power don't even need to electrical heating, do the real energy conservation and environmental protection, at the same time, the whole device is safe, reliable, and no secondary pollution.

本处理装置工艺采用湿法除尘+干式过滤＋吸附＋催化净化装置，工作方式为：一个湿式除尘塔+干式过滤器＋若干个吸附床，经过除尘过滤去除漆雾后，有机废气进入吸附床中进行吸附工作，净化后的气体由风机排入排气筒达标排放。日常工作时吸附床中一个进行脱附再生工作，其余进行吸附工作。脱附时启动催化燃烧器中的电预热器，待温度达到起燃温度时，由脱附风机和补冷风机补入系统中的冷风，经混合后调到适当温度（140℃，其中废气中有机成分沸点：甲苯110.6℃，二甲苯138-144℃）后送入吸附床进行脱附操作，吹脱出的高浓度有机废气（可浓缩10-20倍）与燃烧后的热废气在热交换器中进行热交换得到预热后送入燃烧室，在燃烧室中升到起燃温度后由催化剂将有机物氧化分解为无害的CO2和H2O。燃烧后的废气经脱附出的气体热交换温度降低至180-200℃后用于脱附，多余废气排入排气筒。
由多个吸附床轮流进行吸附和脱附再生，吸附与脱附之间切换，连续运行（工作时间可根据企业生产情况调节）。本工程设计废气浓度100ppm，浓缩后有机废气浓度可达到5000mg/m3以上，在燃烧器启动通过电加热升温至起燃温度后，可维持自燃。

四、催化燃烧和活性炭吸附脱附技术优点：
1、起燃温度低,节省能源

2、适用范围广
催化燃烧几乎可以处理所有的烃类有机废气及恶臭气体。对于有机化工、涂料、绝缘材料等行业排放的低浓度、多成分、无回收价值的废气,采用吸附--催化燃烧法的处理效果更好。
3、处理效率高,无二次污染
用催化燃烧法处理有机废气的净化率一般都在95%以上,最终产物为无害的CO2 和H2O (杂原子有机化合物还有其他燃烧产物),且由于燃烧温度低,能大量减少NOX 的生成,因此不会造成二次污染。但是其缺点是工艺条件要求严格，不允许废气中含有影响催化剂寿命和处理效率的尘粒和雾滴，也不允许有使催化剂中毒的物质，以防催化剂中毒，因此采用催化燃烧技术处理有机废气必须对废气作前处理。
