在低温下，大风量吸附风机通过滤箱过滤掉车间内的挥发性有机物，然后通过沸石分子筛轮吸附，通过沸石轮吸附的气体可直接排放。
At low temperatures, the high airflow adsorption fan filters out volatile organic compounds in the workshop through a filter box, and then adsorbs them through zeolite molecular sieve wheels. The gas adsorbed through the zeolite wheels can be directly discharged.
当吸附大量挥发性有机物的沸石转轮进入高温脱附区时，小风量的热空气将沸石转轮上的挥发性有机物分子脱附，转化为高浓度废气，并将脱附风机送入后端的催化燃烧系统进行催化燃烧处理。分解产生的热量部分通过内部热交换再次进入催化燃烧系统，以减少能量损失，部分分解后的气体直接排放到空气中。
When the zeolite wheel that adsorbs a large amount of volatile organic compounds enters the high-temperature desorption zone, the small amount of hot air will desorb the volatile organic compound molecules on the zeolite wheel, convert them into high concentration waste gas, and send the desorbed fan to the catalytic combustion system at the rear end for catalytic combustion treatment. The heat generated by decomposition enters the catalytic combustion system again through internal heat exchange to reduce energy loss, and some of the decomposed gases are directly discharged into the air.

在此过程中，电气控制系统严格控制催化燃烧产生的热量。当超过设定值时，通过调整脱附管道的自动阀门来补充冷空气，降低废气浓度，减少热量产生；两个分子系统相互结合，反复循环。无VOCS时，设备可停止运行。同时，为了设备的处理和，在停止催化氧化系统后，应冷却这些设备，以保护设备的正常使用。
During this process, the electrical control system strictly controls the heat generated by catalytic combustion. When the set value is exceeded, adjust the automatic valve of the desorption pipeline to supplement cold air, reduce the concentration of exhaust gas, and reduce heat generation; Two molecular systems combine with each other and cycle repeatedly. When there is no VOCS, the device can stop running. At the same time, for the treatment and safety of equipment, after stopping the catalytic oxidation system, these equipment should be cooled to protect their normal use.
二、沸石分子筛转轮吸附浓缩。
2、 Zeolite molecular sieve wheel adsorption concentration.
沸石是一种晶体矿石，我们使用的沸石分子筛是沸石的化合物。
Zeolite is a crystalline ore, and the zeolite molecular sieve we use is a compound of zeolite.
沸石分子筛轮分为吸附区、脱附区和冷却区三部分，每部分由耐热、耐溶剂密封材料分开。沸石轮可在各功能区连续运行，同时吸附脱附冷却。
The zeolite molecular sieve wheel is divided into three parts: adsorption zone, desorption zone, and cooling zone, with each part separated by heat-resistant and solvent resistant sealing materials. The zeolite wheel can operate continuously in various functional areas while adsorbing, desorbing, and cooling.
通过前端过滤器进行初步过滤后，VOCS被沸石分子筛吸附到沸石分子筛转轮的吸附区。有机废气净化后，直接从沸石分子筛转轮排出，通过烟囱进入空气。
After preliminary filtration through the front-end filter, VOCS is adsorbed by the zeolite molecular sieve to the adsorption area of the zeolite molecular sieve wheel. After purifying the organic waste gas, it is directly discharged from the zeolite molecular sieve wheel and enters the air through the chimney.
旋转轮上吸附的VOCS在脱附区被脱附，风量约200℃。浓缩，浓缩倍数一般为5~25倍。浓缩倍数n=吸附面积*吸附速度/脱附面积/脱附速度。
The VOCS adsorbed on the rotating wheel is desorbed in the desorption zone, with an air volume of about 200 ℃. Concentration, the concentration ratio is generally 5-25 times. Concentration factor n=adsorption area * adsorption rate/desorption area/desorption rate.
脱附后的沸石轮在冷却区冷却。冷却区空气加热后作为再生空气，达到效果。上述过程反复循环，以达到废气净化的目的。
The detached zeolite wheel is cooled in the cooling zone. The air in the cooling zone is heated and used as regenerative air to achieve energy-saving effects. The above process is repeated to achieve the purpose of exhaust gas purification.
催化燃烧。
Catalytic combustion.
沸石转轮通过脱附区后，VOCS进入脱附管道，通过脱附风机进入换热器换热。VOCS将催化燃烧产生的部分热量带入催化燃烧器，加热和加热催化剂催化处理。催化燃烧技术可在低温（300℃~500℃）下实现VOCS95%以上的净化效率，完全反应后产生CO2和H2O，同时释放大量热量。
After the zeolite runner passes through the desorption zone, VOCS enters the desorption pipeline and enters the heat exchanger for heat exchange through the desorption fan. VOCS brings some of the heat generated by catalytic combustion into the catalytic burner, heating and heating the catalyst for catalytic treatment. Catalytic combustion technology can achieve a purification efficiency of over 95% of VOCS at low temperatures (300 ℃~500 ℃), producing CO2 and H2O after complete reaction, while releasing a large amount of heat.
郑州客户厂区安装了RCO催化燃烧设备。

部分热量通过混合罐进入旋转轮脱附区，将吸附在旋转轮上的挥发性有机物脱附；部分进入换热器换热，部分热量通过烟囱排出，部分通过换热器的挥发性有机物再次进入催化燃烧器。反复回收可以限度地减少能量损失，实现废气自催化分解的效果。
Part of the heat enters the rotary wheel desorption zone through the mixing tank to desorb the volatile organic compounds adsorbed on the rotary wheel; Part of the heat enters the heat exchanger for heat exchange, part of the heat is discharged through the chimney, and part of the volatile organic compounds that pass through the heat exchanger enter the catalytic burner again. Repeated recycling can minimize energy loss and achieve the effect of exhaust gas self catalytic decomposition.
