The waste gas to be treated by the combination process of zeolite wheel adsorption and desorption+CO passes through a dry filter, and after impurities are filtered out by the dry filter, the waste gas enters the zeolite wheel. The gas that is adsorbed and treated by the zeolite wheel meets the standard and is discharged into the atmosphere. The desorption fan extracts a portion of the gas from the discharge outlet of the impeller, which is heated by the secondary heat exchanger of the CO combustion furnace, and then enters the desorption section of the impeller. The electric heater is controlled to turn on according to the inlet temperature of the impeller desorption, ensuring that the desorption temperature is ≥ 180. If you choose the zeolite wheel CO throwing type, you can find Hebei Qingda Environmental Protection Machinery Co., Ltd. The zeolite concentration wheel+catalytic combustion system is a device that our company has selected for many years based on practical engineering experience, suitable for processing high air volume and low concentration volatile organic waste gas. The system mainly consists of pre-treatment device, zeolite concentration rotary device, catalytic purification device, fan, chimney, etc.

系統(tǒng)原理：主要利用沸石分子篩的多孔吸附性及催化燃燒在溫度300-400在催化劑的作用下將有機組分中的C、H化合物氧化成無害的CO2、H2O等。裝置原理及特點（1）吸附性能佳：沸石轉輪具有與活性炭一樣多微孔的吸附特性；

System principle: It mainly utilizes the porous adsorption of zeolite molecular sieves and catalytic combustion to oxidize C and H compounds in organic components into harmless CO2, H2O, etc. under the action of catalysts at temperatures of 300-400. Principle and characteristics of the device (1) Excellent adsorption performance: The zeolite wheel has the same porous adsorption characteristics as activated carbon;

(2) Stability: The honeycomb zeolite impeller has stable performance, corrosion resistance, and resistance to high-speed airflow impact;

（3）凈化：凈化達95%；

(3) Purification: Purification reaches 95%;

（4）再生性能好：沸石轉輪吸附飽和后可用熱空氣脫附再生，沸石轉輪+CO撬裝式一體機廠家，再生溫度較高可達200，因此再生徹底。

(4) Good regeneration performance: After the zeolite wheel is saturated with adsorption, hot air can be used for desorption and regeneration. The manufacturer of the zeolite wheel+CO pry mounted integrated machine has a high regeneration temperature of up to 200, so the regeneration is thorough.

（5）轉輪濃縮CO燃燒原理：再生后沸石轉輪重新投入使用，通過控制脫附過程流量可將有機廢氣濃度濃縮10-20倍，脫附氣流經催化床的加熱器裝置加熱至300左右，在催化劑作用下起燃，催化燃燒過程凈化效率可達97%以上，燃燒后生成RCO2 和H2O 并釋放出大量熱量，該熱量通過催化燃燒床內的熱交換器一部分再用來加熱脫附出的高濃度廢氣，沸石轉輪+CO撬裝式一體機，另外一部分加熱室外來的空氣做沸石轉輪脫附氣體使用，一般達到脫附～催化燃燒自平衡過程須啟動燃燒器1小時左右。達到熱平衡后可關閉電加熱裝置，沸石轉輪+CO撬裝式一體機定制，這時再生處理系統(tǒng)靠廢氣中的做燃料，在無須外加能源基礎上使再生過程達到自平衡循環(huán)，極大地減少能耗，并且無二次污染的產生，整套吸附和催化燃燒過程由PLC實現(xiàn)自動控制。

(5) The principle of CO concentration combustion by rotary wheel: After regeneration, the zeolite rotary wheel is put back into use. By controlling the flow rate of the desorption process, the concentration of organic waste gas can be concentrated 10-20 times. The desorption gas flows through the heater device of the catalytic bed and is heated to about 300. Under the action of the catalyst, it ignites, and the purification efficiency of the catalytic combustion process can reach over 97%. After combustion, RCO2 and H2O are generated, releasing a large amount of heat, This heat is partially used by the heat exchanger inside the catalytic combustion bed to heat the high concentration exhaust gas that is desorbed. The zeolite wheel+CO pry mounted integrated machine is used, and the air outside the heating chamber is used as the zeolite wheel desorbed gas. Generally, the process of desorbing to catalytic combustion self equilibrium requires the burner to be started for about 1 hour. After reaching thermal equilibrium, the electric heating device can be turned off, and the zeolite wheel+CO pry mounted integrated machine can be customized. At this time, the regeneration treatment system relies on the fuel in the exhaust gas to achieve a self balancing cycle in the regeneration process without the need for additional energy, greatly reducing energy consumption and avoiding the generation of secondary pollution. The entire adsorption and catalytic combustion process is automatically controlled by PLC.

工藝流程:

Process flow:

1）甲方廢氣先經過干式過濾預處理箱體去除廢氣中的粉塵等顆粒物，防止該類物質進入到沸石轉輪中引起轉輪效率下降；

1) The exhaust gas of Party A is first subjected to dry filtration pretreatment box to remove dust and other particulate matter from the exhaust gas, preventing such substances from entering the zeolite wheel and causing a decrease in wheel efficiency;

2）經預處理后的廢氣，進入沸石轉輪吸附區(qū)，廢氣中的VOCs被吸附、凈化后直接達標排放，而吸附過VOCs的沸石隨轉輪轉動進入冷卻區(qū)，在原有廢氣風量15~25分之一的常溫氣體作用下冷卻下來（110），隨后在冷卻風機作用下經電加熱器預熱至脫附溫度：180~220（亦可以通過催化床排放高溫氣體換熱預熱），將VOCs從沸石中脫附出來，形成小風量、高濃度的VOCs尾氣；

2) After pre-treatment, the exhaust gas enters the zeolite wheel adsorption area. VOCs in the exhaust gas are adsorbed and purified before directly meeting the emission standards. Zeolites that have adsorbed VOCs enter the cooling area with the rotation of the wheel, and are cooled by a room temperature gas with an original exhaust gas flow rate of 15-25 times (110). Then, under the action of a cooling fan, they are preheated by an electric heater to a desorption temperature of 180-220 (or can be preheated by discharging high-temperature gas through a catalytic bed for heat exchange), Desorb VOCs from zeolite to form low air volume and high concentration VOCs exhaust gas;

3）脫附產生的高濃尾氣（30~60）在CO系統(tǒng)風機作用下經換熱器預熱升溫、電加熱器加熱至催化劑活性溫度（300）后，進入催化床并發(fā)生氧化分解反應、同時放出熱量，該反應形成的高溫尾氣再依次與轉輪冷卻氣、脫附氣換熱后排放。

3) The high concentration exhaust gas (30-60) generated by desorption is preheated and heated by a heat exchanger under the action of a CO system fan, and then heated by an electric heater to the catalyst activity temperature (300). It enters the catalytic bed and undergoes oxidation decomposition reaction, while releasing heat. The high-temperature exhaust gas formed by this reaction is then heat exchanged with the cooling gas and desorption gas of the impeller before being discharged.
