一、沸石转轮+RTO（蓄热式氧化器）工艺:

　　1、 Zeolite Wheel+RTO (Regenerative Oxidizer) Process:

　　是一种高效的VOCs（挥发性有机化合物）废气处理技术，特别适用于处理大风量、中低浓度的有机废气。这套工艺结合了沸石转轮的浓缩能力和RTO的氧化分解能力，实现了节能减排和经济运行的目标。

　　It is an efficient VOCs (volatile organic compound) waste gas treatment technology, particularly suitable for treating high air volume, low to medium concentration organic waste gas. This process combines the concentration capacity of zeolite rotors with the oxidative decomposition capacity of RTO, achieving the goals of energy conservation, emission reduction, and economic operation.

　　沸石转轮吸附浓缩:

　　Zeolite rotary adsorption concentration:

　　沸石转轮是一种旋转式的吸附装置，其核心是由沸石分子筛组成的蜂窝状结构。沸石具有高度的亲水性和选择性吸附能力，能够从废气中捕捉并浓缩VOCs。沸石转轮分为三个区域：吸附区、解吸（再生）区和冷却区。

　　Zeolite wheel is a rotary adsorption device, with a honeycomb structure composed of zeolite molecular sieves at its core. Zeolite has high hydrophilicity and selective adsorption ability, which can capture and concentrate VOCs from exhaust gas. The zeolite wheel is divided into three zones: adsorption zone, desorption (regeneration) zone, and cooling zone.

　　1. 吸附区：低浓度的有机废气通过沸石转轮的吸附区时，VOCs被沸石分子筛吸附，净化后的气体直接排放。

　　1. Adsorption zone: When low concentration organic waste gas passes through the adsorption zone of the zeolite wheel, VOCs are adsorbed by the zeolite molecular sieve, and the purified gas is directly discharged.

　　2. 解吸（再生）区：沸石转轮旋转到解吸区域时，使用高温空气（通常180-220°C）对沸石进行加热，使吸附的VOCs脱附出来，形成高浓度的VOCs蒸汽。

　　2. Desorption (regeneration) zone: When the zeolite wheel rotates to the desorption zone, high-temperature air (usually 180-220 ° C) is used to heat the zeolite, causing the adsorbed VOCs to desorb and form high concentration VOCs vapor.

　　3. 冷却区：脱附后的沸石通过冷却区恢复吸附能力，准备再次吸附废气中的VOCs。

　　3. Cooling zone: The desorbed zeolite recovers its adsorption capacity through the cooling zone and is ready to adsorb VOCs in the exhaust gas again.

　　RTO蓄热式氧化:

　　RTO Regenerative Oxidation:

　　RTO是一种高效的氧化处理设备，用于将浓缩后的高浓度VOCs氧化分解为二氧化碳和水。其特点是利用蓄热体储存和释放热量，大幅减少能源消耗。

　　RTO is an efficient oxidation treatment equipment used to oxidize and decompose concentrated high concentration VOCs into carbon dioxide and water. Its characteristic is the use of thermal storage to store and release heat, significantly reducing energy consumption.

　　1. 蓄热氧化：浓缩后的VOCs蒸汽被送入RTO，通过蓄热体预热，然后在高温（760-950°C）条件下，VOCs被氧化分解。

　　1. Thermal storage oxidation: The concentrated VOCs vapor is sent to RTO, preheated by a thermal storage body, and then under high temperature (760-950 ° C) conditions, VOCs are oxidized and decomposed.

　　2. 热回收：RTO中的蓄热体能够吸收废气燃烧产生的热量，并在下一循环中预热进入的废气，大大减少了燃料的消耗。

　　2. Heat recovery: The thermal storage body in RTO can absorb the heat generated by the combustion of exhaust gas and preheat the incoming exhaust gas in the next cycle, greatly reducing fuel consumption.

　　沸石转轮+RTO工艺的优势在于，沸石转轮可以将低浓度的大风量废气浓缩，降低RTO处理的气量和能耗，使得整个系统更加经济高效。同时，RTO的热回收机制也进一步降低了运行成本。

　　The advantage of the zeolite wheel+RTO process is that the zeolite wheel can concentrate low concentration high-volume exhaust gas, reduce the gas volume and energy consumption of RTO treatment, and make the entire system more economical and efficient. Meanwhile, the heat recovery mechanism of RTO further reduces operating costs.

　　二、沸石转轮+RTO工艺的主要流程步骤：

　　2、 The main process steps of zeolite wheel+RTO technology are:

　　1. 预处理：废气首先经过预处理系统，如干式或湿式过滤，以去除废气中的颗粒物和其他杂质，确保废气满足沸石转轮吸附的条件。

　　1. Pre treatment: The exhaust gas first goes through a pre-treatment system, such as dry or wet filtration, to remove particulate matter and other impurities from the exhaust gas, ensuring that the exhaust gas meets the conditions for zeolite wheel adsorption.

　　2. 沸石转轮吸附：经过预处理的废气进入沸石转轮，其中的VOCs被沸石分子筛选择性吸附。沸石转轮通常持续缓慢旋转，废气在吸附区被净化。

　　2. Zeolite wheel adsorption: The pre treated exhaust gas enters the zeolite wheel, and the VOCs in it are selectively adsorbed by zeolite molecules. The zeolite wheel usually rotates slowly and continuously, and the exhaust gas is purified in the adsorption zone.

　　3. 脱附阶段： 吸附了VOCs的沸石区域移动至脱附区，通过高温热空气（脱附风）吹扫，将吸附在沸石上的VOCs脱附出来。脱附温度依据废气成分设定，以便有效脱附而不破坏沸石结构。

　　3. Desorption stage: The zeolite region that has adsorbed VOCs moves to the desorption zone and is blown by high-temperature hot air (desorption wind) to desorb the VOCs adsorbed on the zeolite. The desorption temperature is set based on the composition of the exhaust gas in order to effectively desorb without damaging the zeolite structure.

　　4. RTO燃烧阶段： 脱附出的高浓度、小风量的VOCs废气被送入RTO装置。在RTO内，废气被加热至高温（通常约800°C），VOCs被氧化分解为二氧化碳和水蒸气，达到排放标准。

　　4. RTO combustion stage: The high concentration and low airflow VOCs exhaust gas desorbed is sent to the RTO device. In RTO, the exhaust gas is heated to high temperatures (usually around 800 ° C), and VOCs are oxidized and decomposed into carbon dioxide and water vapor, meeting emission standards.

　　5. 热回收:  在RTO中，废气通过蓄热体预热，而燃烧后的高温气体则通过另一组蓄热体释放热量，从而预热进入的新废气，实现热能的高效回收。

　　5. Heat recovery: In RTO, the exhaust gas is preheated by a thermal storage body, and the high-temperature gas after combustion releases heat through another set of thermal storage bodies, thereby preheating the incoming new exhaust gas and achieving efficient heat recovery.

　　6. 冷却与排放：净化后的气体在排放前可能需要通过冷却系统降低温度，然后通过烟囱安全排放到大气中。

　　6. Cooling and emission: The purified gas may need to be cooled by a cooling system before being safely discharged into the atmosphere through a chimney.

　　7. 沸石转轮再生：经过高温脱附的沸石区域需要冷却以恢复其吸附能力，这通常是通过引入冷却空气来实现的。冷却后的沸石区域可以重新投入吸附阶段。

　　7. Zeolite wheel regeneration: The zeolite region that has undergone high-temperature desorption needs to be cooled to restore its adsorption capacity, which is usually achieved by introducing cooling air. The cooled zeolite region can be reintroduced into the adsorption stage.

　　整个流程是一个连续过程，沸石转轮在吸附和脱附之间循环，而RTO则持续运行，处理从沸石转轮脱附出的浓缩废气。这种方法能有效减少废气处理的成本，提高能源效率，确保环境合规性。

　　The entire process is a continuous process, with the zeolite wheel circulating between adsorption and desorption, while the RTO continues to operate to process the concentrated exhaust gas desorbed from the zeolite wheel. This method can effectively reduce the cost of exhaust gas treatment, improve energy efficiency, and ensure environmental compliance.
