沸石轉輪+CO適合低濃度的有機廢氣偏高一些的工況，以印刷行業(yè)為例，針對于印刷行業(yè)有機廢氣很多廠家已經安裝了相應的廢氣處理設備，但是隨著環(huán)保日益嚴重，普通的處理設備長期運行下很難保證排放，所以我公司推薦熱處理工藝-催化燃燒，因為印刷行業(yè)的廢氣特殊性，用活性炭吸附濃縮雖然前期可以達標排放，但是長期運行保證排放還是有一定難度的，因為活性炭脫附溫度受限制，附著物易燃，脫附不，隨著運行時間加長脫附效果減弱，所以我公司推薦用沸石轉輪+CO催化燃燒

Zeolite wheel+CO is suitable for working conditions with low concentration and high organic waste gas. Taking the printing industry as an example, many manufacturers have installed corresponding waste gas treatment equipment for organic waste gas in the printing industry. However, with the increasing severity of environmental protection, it is difficult to ensure emissions under long-term operation of ordinary treatment equipment. Therefore, our company recommends the heat treatment process - catalytic combustion. Due to the special nature of waste gas in the printing industry, although adsorption and concentration with activated carbon can meet the emission standards in the early stage, it is still difficult to ensure emissions under long-term operation. Because the desorption temperature of activated carbon is limited, the attachments are flammable, and the desorption effect weakens with prolonged operation time. Therefore, our company recommends using zeolite wheel+CO catalytic combustion

沸石轉輪吸附脫附+CO組合工藝待處理廢氣經過干式過濾器，由干式過濾器濾除雜質后的廢氣進入沸石轉輪，被沸石轉輪吸附處理后的氣體達標排入大氣中。脫附風機將轉輪排放口的一部分氣體抽吸出來，經過CO燃燒爐的二級換熱器加熱后，進入轉輪的脫附段，根據轉輪脫附進口溫度控制電加熱器的開啟，保證脫附溫度≥180℃。

The waste gas to be treated by the zeolite wheel adsorption desorption+CO combination process passes through a dry filter, and the waste gas filtered out of impurities by the dry filter enters the zeolite wheel. The gas treated by the zeolite wheel adsorption 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 enters the desorption section of the impeller. The electric heater is controlled to turn on according to the inlet temperature of the impeller desorption to ensure that the desorption temperature is ≥ 180 ℃.

If you want to choose the zeolite wheel CO throwing type, look for 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 treating high air volume and low concentration volatile organic waste gas. The system mainly consists of a pretreatment device, a zeolite concentration wheel device, a catalytic purification device, a fan, a chimney, etc.

（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。

(4) Good regeneration performance: After the zeolite wheel is saturated with adsorption, it can be regenerated by hot air desorption. The zeolite wheel+CO integrated machine manufacturer has a high regeneration temperature of up to 200 ℃, so it can be regenerated.

（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)，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) Principle of Rotary CO Concentration Combustion: 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 ℃. It ignites under the action of the catalyst, and the purification efficiency of the catalytic combustion process can reach over 97%. After combustion, RCO2 and H2O are generated and a large amount of heat is released. A part of the heat is used to heat the high concentration waste gas desorbed through the heat exchanger in the catalytic combustion bed. The zeolite rotary wheel+CO modular integrated machine, and the other part of the air outside the heating chamber is used as the desorption gas of the zeolite rotary wheel. Generally, to achieve the self equilibrium process of desorption catalytic combustion, the burner needs to be started for about 1 hour. After reaching thermal equilibrium, the electric heating device can be turned off. The zeolite wheel+CO pry mounted integrated machine is customized. At this time, the regeneration treatment system relies on the fuel in the exhaust gas to achieve self balancing circulation in the regeneration process without the need for external energy, reducing energy consumption and eliminating secondary pollution. The entire adsorption and catalytic combustion process is automatically controlled by PLC.
