沸石转轮+CO适合低浓度的有机废气偏高一些的工况，以印刷行业为例，针对于印刷行业有机废气很多厂家已经安装了相应的废气处理设备，但是随着环保日益严重，普通的处理设备长期运行下很难保证排放，所以我公司推荐热处理工艺-催化燃烧，因为印刷行业的废气特殊性，用活性炭吸附浓缩虽然前期可以达标排放，但是长期运行保证排放还是有一定难度的，因为活性炭脱附温度受限制，附着物易燃，脱附不，随着运行时间加长脱附效果减弱，所以我公司推荐用沸石转轮+CO催化燃烧

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

沸石转轮吸附脱附+CO组合工艺待处理废气经过干式过滤器，由干式过滤器滤除杂质后的废气进入沸石转轮，被沸石转轮吸附处理后的气体达标排入大气中。脱附风机将转轮排放口的一部分气体抽吸出来，经过CO燃烧炉的二级换热器加热后，进入转轮的脱附段，根据转轮脱附进口温度控制电加热器的开启，保证脱附温度≥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) 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）转轮浓缩CO燃烧原理：再生后沸石转轮重新投入使用，通过控制脱附过程流量可将有机废气浓度浓缩10-20倍，脱附气流经催化床的加热器装置加热至300℃左右，在催化剂作用下起燃，催化燃烧过程净化效率可达97%以上，燃烧后生成RCO2 和H2O 并释放出大量热量，该热量通过催化燃烧床内的热交换器一部分再用来加热脱附出的高浓度废气，沸石转轮+CO撬装式一体机，另外一部分加热室外来的空气做沸石转轮脱附气体使用，一般达到脱附～催化燃烧自平衡过程须启动燃烧器1小时左右。达到热平衡后可关闭电加热装置，沸石转轮+CO撬装式一体机定制，这时再生处理系统靠废气中的做燃料，在无须外加能源基础上使再生过程达到自平衡循环，地减少能耗，并且无二次污染的产生，整套吸附和催化燃烧过程由PLC实现自动控制。

(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.
