在工业发展的进程中，挥发性有机化合物（VOCs）的排放成为了环境污染的重要源头之一。VOCs 不仅会对大气环境造成破坏，引发光化学烟雾等环境问题，还会对人体健康产生严重威胁。为了有效治理 VOCs，各种废气处理技术应运而生，其中，沸石转轮与 CO（催化氧化）的组合技术凭借其卓越的性能，成为了当下废气处理领域的明星技术。

In the process of industrial development, the emission of volatile organic compounds (VOCs) has become one of the important sources of environmental pollution. VOCs not only cause damage to the atmospheric environment and lead to environmental problems such as photochemical smog, but also pose a serious threat to human health. In order to effectively control VOCs, various waste gas treatment technologies have emerged, among which the combination technology of zeolite impeller and CO (catalytic oxidation) has become a star technology in the current waste gas treatment field due to its excellent performance.

一、沸石转轮：高效的吸附能手

1、 Zeolite Wheel: Efficient Adsorption Expert

沸石转轮是根据沸石分子筛的吸附和脱附原理专门设计用于处理废气的设备 ，其结构独特，内部为蜂窝状，由沸石材料制成，拥有大量微孔 。这些微孔赋予了沸石转轮强大的吸附能力，能够高效吸附废气中的 VOCs。

Zeolite wheel is a device specially designed for treating exhaust gas based on the adsorption and desorption principles of zeolite molecular sieves. Its unique structure is honeycomb shaped inside, made of zeolite material, and has a large number of micropores. These micropores endow the zeolite wheel with strong adsorption capacity, enabling efficient adsorption of VOCs in exhaust gas.

沸石转轮的工作过程主要分为三个区域：吸附区、脱附区和冷却区。在吸附区，当废气通过沸石转轮时，其中的 VOCs 被吸附在沸石的微孔中，实现废气的初步净化，净化后的废气排空。随着转轮的转动，吸附饱和的部分进入脱附区，通过加热解吸的方式，使吸附在沸石上的 VOCs 脱附下来，此时脱附后的气体浓度得到大幅浓缩 。解吸后的转轮进入冷却区，小部分废气送入冷却区给转轮降温，使其恢复吸附能力，冷却后的空气加热至一定温度后又作为脱附空气进入脱附区，形成循环，实现节能。沸石转轮具有诸多优点，它的吸附效率高，能达到 95% 以上 ，可以实现 5 - 15 倍甚至更高的浓缩倍数 ，这不仅大大减小了后续处理设备的规模，还降低了成本。其吸附过程产生的压降较低，电力消耗大幅减少，运行费用低 。而且，它采用模块化设计，操作简便，维护也相对容易 。

The working process of zeolite wheel is mainly divided into three zones: adsorption zone, desorption zone, and cooling zone. In the adsorption zone, when the exhaust gas passes through the zeolite wheel, the VOCs are adsorbed in the micropores of the zeolite, achieving preliminary purification of the exhaust gas, and the purified exhaust gas is discharged. As the wheel rotates, the saturated adsorption part enters the desorption zone, and the VOCs adsorbed on the zeolite are desorbed by heating, resulting in a significant concentration of the desorbed gas. After desorption, the impeller enters the cooling zone, and a small portion of the exhaust gas is sent to the cooling zone to cool the impeller and restore its adsorption capacity. The cooled air is heated to a certain temperature and then used as desorption air to enter the desorption zone, forming a cycle and achieving energy saving. Zeolite rotary wheels have many advantages, such as high adsorption efficiency of over 95%, which can achieve concentration ratios of 5-15 times or even higher. This not only greatly reduces the scale of subsequent treatment equipment, but also lowers costs. The pressure drop generated during its adsorption process is relatively low, power consumption is significantly reduced, and operating costs are low. Moreover, it adopts a modular design, which is easy to operate and relatively easy to maintain.

二、CO 催化氧化：彻底的净化力量

2、 CO catalytic oxidation: a thorough purification power

CO 催化氧化，即催化燃烧，是在催化剂的作用下，使 VOCs 与空气中的氧气发生氧化反应，生成无害的二氧化碳和水 。这一过程能够将 VOCs 彻底转化为无害物质，实现高效净化。

CO catalytic oxidation, also known as catalytic combustion, involves the oxidation reaction between VOCs and oxygen in the air under the action of a catalyst, producing harmless carbon dioxide and water. This process can thoroughly convert VOCs into harmless substances, achieving efficient purification.

在 CO 催化氧化过程中，催化剂是核心要素。常见的催化剂有贵金属催化剂（如铂、钯等）和非贵金属催化剂 。贵金属催化剂具有活性高、起燃温度低等优点，能够在较低的温度（通常 300 - 400℃）下使 VOCs 发生氧化反应 ，大大降低了能耗和运行成本 。非贵金属催化剂则具有成本较低的优势，在一些对成本控制较为严格的场景中也有应用。CO 催化氧化反应效率高，能够使废气中的 VOCs 得到深度净化，满足严格的环保排放标准。而且，由于反应温度相对较低，减少了氮氧化物等二次污染物的产生，更加环保。

In the process of CO catalytic oxidation, the catalyst is the core element. Common catalysts include precious metal catalysts (such as platinum, palladium, etc.) and non precious metal catalysts. Precious metal catalysts have the advantages of high activity and low ignition temperature, which can oxidize VOCs at lower temperatures (usually 300-400 ℃), greatly reducing energy consumption and operating costs. Non precious metal catalysts have the advantage of lower cost and are also applied in some scenarios with strict cost control. The CO catalytic oxidation reaction has high efficiency and can deeply purify VOCs in exhaust gas, meeting strict environmental emission standards. Moreover, due to the relatively low reaction temperature, the production of secondary pollutants such as nitrogen oxides is reduced, making it more environmentally friendly.

三、沸石转轮 + CO：强强联合，优势尽显

3、 Zeolite wheel+CO: Strong combination, advantages fully demonstrated

将沸石转轮与 CO 催化氧化结合，形成了一套高效的废气处理系统。沸石转轮先对大风量、低浓度的有机废气进行吸附浓缩，将低浓度的 VOCs 富集起来，形成高浓度的气体，然后送入 CO 反应器进行催化氧化 。这种组合方式充分发挥了两者的优势。

The combination of zeolite impeller and CO catalytic oxidation forms an efficient exhaust gas treatment system. The zeolite wheel first adsorbs and concentrates high air volume and low concentration organic waste gas, enriching low concentration VOCs to form high concentration gas, which is then sent to the CO reactor for catalytic oxidation. This combination fully leverages the advantages of both.

处理效率极高，对于大风量、低浓度的有机废气，单一的处理方式往往难以达到理想效果，而沸石转轮 + CO 系统能够实现对这类废气的高效吸附和深度净化，满足各种严格的废气处理需求 。系统设计紧凑，占地面积小 ，这对于一些场地有限的企业来说非常重要，能够有效节省空间。其采用先进的自动化控制系统，不仅操作简便，还配备了故障预警系统，大大提高了设备运行的安全性和稳定性 。沸石转轮 + CO 一体机在节能环保方面表现出色，一方面，沸石转轮的吸附过程能耗低，另一方面，CO 催化氧化在相对较低的温度下进行，减少了能源消耗，且整个处理过程不产生二次污染 。

The processing efficiency is extremely high. For organic waste gases with high air volume and low concentration, a single treatment method is often difficult to achieve ideal results. However, the zeolite wheel+CO system can achieve efficient adsorption and deep purification of such waste gases, meeting various strict waste gas treatment requirements. The system design is compact and occupies a small area, which is very important for some enterprises with limited space and can effectively save space. It adopts advanced automation control system, which is not only easy to operate, but also equipped with fault warning system, greatly improving the safety and stability of equipment operation. The zeolite wheel+CO integrated machine performs well in energy conservation and environmental protection. On the one hand, the adsorption process of zeolite wheel has low energy consumption. On the other hand, CO catalytic oxidation is carried out at relatively low temperatures, reducing energy consumption and the entire treatment process does not produce secondary pollution.

Zeolite rotary wheel+CO integrated machine is widely used in many industries. In the spray painting and automotive spray painting manufacturing industries, a large amount of waste gas containing VOCs such as benzene derivatives, alcohols, and ketones is generated during the spray painting process. By treating the waste gas with a zeolite wheel and CO system, it can effectively purify the waste gas and reduce environmental pollution. In the printing and ink printing and dyeing industry, the exhaust gas composition is complex and contains various volatile organic compounds. This system can also leverage its efficient treatment advantages to ensure that the exhaust gas meets the emission standards. In industries such as chemical, injection molding, and coating, VOCs in exhaust gases can also be efficiently removed, protecting the production environment and the health of employees. In addition, in industries such as electronic product manufacturing and semiconductor manufacturing, due to the high requirements for the production environment, the zeolite wheel+CO integrated machine can effectively improve the air quality in the workshop and ensure the smooth progress of production.
