催化燃燒裝置的工作流程，包含以下模塊：廢氣的收集、預(yù)處理、活性炭載體的吸附、co爐燃燒裝置和末端風(fēng)機煙筒的排放。其中，有三大模塊是催化燃燒的核心裝置：

　　The workflow of catalytic combustion device includes the following modules: collection and pretreatment of exhaust gas, adsorption of activated carbon carrier, CO furnace combustion device, and exhaust of end fan chimney. Among them, there are three major modules that are the core devices of catalytic combustion:

　　1、預(yù)處理對廢氣顆粒物雜質(zhì)的有效攔截，廢氣的潔凈程度是直接關(guān)乎活性炭壽命的根本。2、活性炭的選擇為高質(zhì)量木質(zhì)或椰殼碳，碘值不低于600，四氯化碳不低于50%。3、催化劑的貴金屬含量是催化燃燒的核心問題，是脫附活性炭廢氣能否達(dá)到無焰燃燒的關(guān)鍵所在。

　　1. The effective interception of particulate matter impurities in exhaust gas by pretreatment is directly related to the cleanliness of exhaust gas, which is fundamental to the lifespan of activated carbon. 2. The selection of activated carbon is high-quality wood or coconut shell carbon, with an iodine value not less than 600 and carbon tetrachloride not less than 50%. 3. The content of precious metals in catalysts is the core issue of catalytic combustion and the key to achieving flameless combustion of desorbed activated carbon exhaust gas.

　　廢氣燃燒溫度一般在260-300℃之間。燃燒后，廢氣再次進(jìn)入熱交換器。經(jīng)換熱器冷卻后，凈化后的廢氣經(jīng)離心風(fēng)機和15米煙囪排入大氣。

　　The combustion temperature of exhaust gas is generally between 260-300 ℃. After combustion, the exhaust gas enters the heat exchanger again. After being cooled by a heat exchanger, the purified exhaust gas is discharged into the atmosphere through a centrifugal fan and a 15 meter chimney.

　　廢氣經(jīng)阻火器過濾后，通過脫附管道進(jìn)入熱交換器，熱交換器的熱氣升高一定溫度后進(jìn)入預(yù)熱室、經(jīng)過預(yù)熱室的加熱使廢氣升溫到催化起燃溫度（260度）然后進(jìn)入催化反應(yīng)床，在催化劑的活性作用下，有機廢氣進(jìn)行氧化反應(yīng)生成無害的水和二氧化碳，并放出一定的熱量。反應(yīng)后的高溫氣體再次進(jìn)入熱交換器，經(jīng)換熱后，高溫氣體通過脫附管道進(jìn)入脫附碳箱，形成循環(huán)脫附。催化燃燒是借助催化劑在低溫下（260－400度）實現(xiàn)對有機物的完全氧化，因此，操作簡單、凈化效率高，在有機廢氣特別是回收價值大的有機廢氣凈化等領(lǐng)域應(yīng)用廣泛。

　　After being filtered by the flame arrester, the exhaust gas enters the heat exchanger through the desorption pipeline. The hot gas in the heat exchanger rises to a certain temperature and enters the preheating chamber. After being heated by the preheating chamber, the exhaust gas is heated to the catalytic ignition temperature (260 degrees) and then enters the catalytic reaction bed. Under the active action of the catalyst, the organic exhaust gas undergoes oxidation reaction to produce harmless water and carbon dioxide, and releases a certain amount of heat. The high-temperature gas after the reaction enters the heat exchanger again, and after heat exchange, the high-temperature gas enters the desorption carbon box through the desorption pipeline, forming a cyclic desorption. Catalytic combustion utilizes catalysts to achieve complete oxidation of organic matter at low temperatures (260-400 degrees). Therefore, it is easy to operate and has high purification efficiency. It is widely used in the purification of organic waste gases, especially those with high recovery value.

　　催化燃燒與催化燃燒一體化環(huán)保單元的工作原理主要包括吸附氣法、分析氣法和催化燃燒法三部分。(1)吸附氣法利用活性炭的物理特性吸附VOC有機廢氣。蜂窩活性炭比表面積大，吸附能力強。有機廢氣吸附到活性炭微孔中進(jìn)行凈化，凈化后的氣體通過風(fēng)機排出;(2)在氣體解吸過程中，當(dāng)活性炭微孔吸附飽和時，不能被吸附。此時，催化床產(chǎn)生的高溫?zé)犸L(fēng)解吸活性炭，活性炭微孔有機物在高溫下自動與活性炭分離，活性炭再生;(3)有機物解吸后被濃縮(濃度比原來高出數(shù)十倍)，送入催化燃燒室進(jìn)行催化燃燒。在250~300℃的催化劑上進(jìn)行催化氧化，轉(zhuǎn)化為無害的CO2和H2O排放。當(dāng)有機廢氣濃度達(dá)到2000ppm以上時，有機廢氣可以在催化床中保持自燃，無需額外加熱。燃燒后的尾氣直接排放到大氣中，大部分熱空氣回收到吸附床進(jìn)行活性炭的分析和再生。再生后的活性炭可用于下次吸附。該設(shè)備可在兩條氣路下連續(xù)工作。當(dāng)工作負(fù)荷較大時，設(shè)置兩個吸附床交替使用。建立了催化燃燒室。首先，有機廢氣由其中一個活性炭吸附床吸附。當(dāng)活性炭接近飽和時，吸附床兩端關(guān)閉的閥門同時關(guān)閉，即停止吸附工作，另一個吸附床自動打開，開始接管吸附工作。這樣，兩個吸附床的切換操作可以實現(xiàn)大量的連續(xù)工作。

　　The working principle of catalytic combustion and catalytic combustion integrated environmental protection unit mainly includes three parts: adsorption gas method, analytical gas method, and catalytic combustion method. (1) The adsorption gas method utilizes the physical properties of activated carbon to adsorb VOC organic waste gas. Honeycomb activated carbon has a large specific surface area and strong adsorption capacity. Organic waste gas is adsorbed into activated carbon micropores for purification, and the purified gas is discharged through a fan; (2) During the gas desorption process, when the activated carbon micropores are saturated with adsorption, they cannot be adsorbed. At this point, the high-temperature hot air generated by the catalytic bed desorbs the activated carbon, and the microporous organic matter in the activated carbon automatically separates from the activated carbon at high temperatures, leading to the regeneration of the activated carbon; (3) After desorption, the organic matter is concentrated (with a concentration tens of times higher than before) and sent to the catalytic combustion chamber for catalytic combustion. Catalytic oxidation is carried out on a catalyst at 250~300 ℃ to convert into harmless CO2 and H2O emissions. When the concentration of organic waste gas reaches over 2000ppm, the organic waste gas can maintain spontaneous combustion in the catalytic bed without the need for additional heating. The exhaust gas after combustion is directly discharged into the atmosphere, and most of the hot air is recovered to the adsorption bed for analysis and regeneration of activated carbon. The regenerated activated carbon can be used for the next adsorption. This device can work continuously under two gas paths. When the workload is high, set up two adsorption beds to be used alternately. Established a catalytic combustion chamber. Firstly, the organic waste gas is adsorbed by one of the activated carbon adsorption beds. When the activated carbon approaches saturation, the valves at both ends of the adsorption bed are closed simultaneously, which stops the adsorption work. The other adsorption bed automatically opens and begins to take over the adsorption work. In this way, the switching operation of the two adsorption beds can achieve a large amount of continuous work.
