在工业生产过程中，挥发性有机化合物（VOCs）废气的排放是一个严重的环境问题。这些废气不仅会对空气质量造成污染，还可能危害人体健康。沸石转轮废气处理技术作为一种高效、节能的 VOCs 治理方法，正逐渐成为工业废气净化领域的关键技术。

The emission of volatile organic compounds (VOCs) in industrial production processes is a serious environmental problem. These exhaust gases not only pollute the air quality, but may also pose a threat to human health. The zeolite wheel exhaust gas treatment technology, as an efficient and energy-saving VOCs treatment method, is gradually becoming a key technology in the field of industrial exhaust gas purification.

一、工作原理

1、 Working principle

沸石转轮废气处理技术的核心在于利用沸石的吸附特性。沸石是一种具有多孔结构的硅铝酸盐矿物质，其内部拥有大量均匀且微小的孔径，比表面积大，这使得沸石对 VOCs 具有很强的吸附能力。

The core of zeolite wheel exhaust gas treatment technology lies in utilizing the adsorption properties of zeolite. Zeolite is a silicate mineral with a porous structure, which has a large number of uniform and small pore sizes inside, and a large specific surface area. This makes zeolite highly capable of adsorbing VOCs.

沸石转轮通常被划分为吸附区、脱附区和冷却区三个功能区域。当含有 VOCs 的废气在风机的作用下进入吸附区时，废气中的 VOCs 分子被沸石转轮上的沸石吸附，从而实现废气的初步净化。随着沸石转轮的缓慢转动，吸附饱和的沸石区域进入脱附区。在脱附区，通过引入高温热风，使沸石上吸附的 VOCs 分子受热脱附，形成高浓度的 VOCs 废气。脱附后的沸石转轮进入冷却区，被冷却至适宜的吸附温度，以便再次进入吸附区进行吸附工作，如此循环往复。

Zeolite rotors are usually divided into three functional zones: adsorption zone, desorption zone, and cooling zone. When the exhaust gas containing VOCs enters the adsorption zone under the action of the fan, the VOCs molecules in the exhaust gas are adsorbed by the zeolite on the zeolite wheel, thereby achieving preliminary purification of the exhaust gas. As the zeolite wheel slowly rotates, the adsorption saturated zeolite region enters the desorption zone. In the desorption zone, by introducing high-temperature hot air, the VOCs molecules adsorbed on the zeolite are heated and desorbed, forming high concentration VOCs waste gas. After desorption, the zeolite wheel enters the cooling zone and is cooled to the appropriate adsorption temperature, so as to enter the adsorption zone again for adsorption work, and so on in a cyclic manner.

脱附出来的高浓度 VOCs 废气，后续通常会进入燃烧设备（如 RTO、RCO 等）进行进一步处理，在高温下被分解为二氧化碳和水等无害物质，最终达标排放。

The high concentration VOCs exhaust gas desorbed usually enters combustion equipment (such as RTO, RCO, etc.) for further treatment, and is decomposed into harmless substances such as carbon dioxide and water at high temperatures, ultimately meeting emission standards.

二、系统组成

2、 System composition

沸石转轮：这是整个系统的核心部件，由涂覆有沸石的陶瓷纤维纸卷制而成，呈蜂窝状结构，具有较大的比表面积和良好的吸附性能。

Zeolite wheel: This is the core component of the entire system, made of ceramic fiber paper coated with zeolite, with a honeycomb structure, a large specific surface area, and good adsorption performance.

废气预处理装置：为了保护沸石转轮，延长其使用寿命，在废气进入沸石转轮之前，需要进行预处理。预处理装置通常包括过滤器、冷凝器等，用于去除废气中的颗粒物、水分和粘性物质等杂质。

Exhaust gas pretreatment device: In order to protect the zeolite wheel and extend its service life, pre-treatment is required before the exhaust gas enters the zeolite wheel. Pre treatment devices typically include filters, condensers, etc., used to remove impurities such as particulate matter, moisture, and viscous substances from exhaust gas.

热风循环系统：主要用于提供脱附所需的高温热风。该系统包括加热器、风机、管道等组件，通过控制热风的温度、流量和流向，确保沸石转轮的脱附过程高效稳定进行。

Hot air circulation system: mainly used to provide high-temperature hot air required for desorption. The system includes components such as heaters, fans, and pipelines. By controlling the temperature, flow rate, and direction of the hot air, it ensures the efficient and stable desorption process of the zeolite wheel.

燃烧装置：用于处理脱附出来的高浓度 VOCs 废气。常见的燃烧装置有蓄热式热力焚烧炉（RTO）和蓄热式催化燃烧炉（RCO）。RTO 利用陶瓷蓄热体储存热量，使废气在高温下充分燃烧；RCO 则在催化剂的作用下，降低燃烧温度，实现 VOCs 的低温燃烧，减少能源消耗。

Combustion device: used to treat high concentration VOCs waste gas desorbed. Common combustion devices include regenerative thermal incinerators (RTOs) and regenerative catalytic combustion furnaces (RCOs). RTO utilizes ceramic thermal storage to store heat, allowing exhaust gases to burn fully at high temperatures; RCO, under the action of catalyst, reduces the combustion temperature, achieves low-temperature combustion of VOCs, and reduces energy consumption.
