一、沸石轉輪+RTO（蓄熱式氧化器）工藝:

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

　　是一種高效的VOCs（揮發性有機化合物）廢氣處理技術，特別適用于處理大風量、中低濃度的有機廢氣。這套工藝結合了沸石轉輪的濃縮能力和RTO的氧化分解能力，實現了節能減排和經濟運行的目標。

　　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.

　　沸石轉輪吸附濃縮:

　　Zeolite rotary adsorption concentration:

　　沸石轉輪是一種旋轉式的吸附裝置，其核心是由沸石分子篩組成的蜂窩狀結構。沸石具有高度的親水性和選擇性吸附能力，能夠從廢氣中捕捉并濃縮VOCs。沸石轉輪分為三個區域：吸附區、解吸（再生）區和冷卻區。

　　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. 吸附區：低濃度的有機廢氣通過沸石轉輪的吸附區時，VOCs被沸石分子篩吸附，凈化后的氣體直接排放。

　　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）區：沸石轉輪旋轉到解吸區域時，使用高溫空氣（通常180-220°C）對沸石進行加熱，使吸附的VOCs脫附出來，形成高濃度的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. 冷卻區：脫附后的沸石通過冷卻區恢復吸附能力，準備再次吸附廢氣中的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蓄熱式氧化:

　　RTO Regenerative Oxidation:

　　RTO是一種高效的氧化處理設備，用于將濃縮后的高濃度VOCs氧化分解為二氧化碳和水。其特點是利用蓄熱體儲存和釋放熱量，大幅減少能源消耗。

　　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. 蓄熱氧化：濃縮后的VOCs蒸汽被送入RTO，通過蓄熱體預熱，然后在高溫（760-950°C）條件下，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. 熱回收：RTO中的蓄熱體能夠吸收廢氣燃燒產生的熱量，并在下一循環中預熱進入的廢氣，大大減少了燃料的消耗。

　　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.

　　沸石轉輪+RTO工藝的優勢在于，沸石轉輪可以將低濃度的大風量廢氣濃縮，降低RTO處理的氣量和能耗，使得整個系統更加經濟高效。同時，RTO的熱回收機制也進一步降低了運行成本。

　　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、沸石轉輪+RTO工藝的主要流程步驟：

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

　　1. 預處理：廢氣首先經過預處理系統，如干式或濕式過濾，以去除廢氣中的顆粒物和其他雜質，確保廢氣滿足沸石轉輪吸附的條件。

　　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. 沸石轉輪吸附：經過預處理的廢氣進入沸石轉輪，其中的VOCs被沸石分子篩選擇性吸附。沸石轉輪通常持續緩慢旋轉，廢氣在吸附區被凈化。

　　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. 脫附階段： 吸附了VOCs的沸石區域移動至脫附區，通過高溫熱空氣（脫附風）吹掃，將吸附在沸石上的VOCs脫附出來。脫附溫度依據廢氣成分設定，以便有效脫附而不破壞沸石結構。

　　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燃燒階段： 脫附出的高濃度、小風量的VOCs廢氣被送入RTO裝置。在RTO內，廢氣被加熱至高溫（通常約800°C），VOCs被氧化分解為二氧化碳和水蒸氣，達到排放標準。

　　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. 熱回收:  在RTO中，廢氣通過蓄熱體預熱，而燃燒后的高溫氣體則通過另一組蓄熱體釋放熱量，從而預熱進入的新廢氣，實現熱能的高效回收。

　　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. 冷卻與排放：凈化后的氣體在排放前可能需要通過冷卻系統降低溫度，然后通過煙囪安全排放到大氣中。

　　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. 沸石轉輪再生：經過高溫脫附的沸石區域需要冷卻以恢復其吸附能力，這通常是通過引入冷卻空氣來實現的。冷卻后的沸石區域可以重新投入吸附階段。

　　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.

　　整個流程是一個連續過程，沸石轉輪在吸附和脫附之間循環，而RTO則持續運行，處理從沸石轉輪脫附出的濃縮廢氣。這種方法能有效減少廢氣處理的成本，提高能源效率，確保環境合規性。

　　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.
