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.

(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.

工艺流程:

Process flow:

1）甲方废气先经过干式过滤预处理箱体去除废气中的粉尘等颗粒物，防止该类物质进入到沸石转轮中引起转轮效率下降；

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）经预处理后的废气，进入沸石转轮吸附区，废气中的VOCs被吸附、净化后直接达标排放，而吸附过VOCs的沸石随转轮转动进入冷却区，在原有废气风量15~25分之一的常温气体作用下冷却下来（110），随后在冷却风机作用下经电加热器预热脱附温度：180~220（亦可以通过催化床排放高温气体换热预热），将VOCs从沸石中脱附出来，形成小风量、高浓度的VOCs尾气；

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）脱附产生的高浓尾气（30~60）在CO系统风机作用下经换热器预热升温、电加热器加热催化剂活性温度（300）后，进入催化床并发生氧化分解反应、同时放出热量，该反应形成的高温尾气再依次与转轮冷却气、脱附气换热后排放。

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.
