废气预处理：有机废气首先进入预处理系统，通过过滤、除湿等操作，去除废气中的颗粒物、水分等杂质，以保护后续设备并提高处理效率。

Waste gas pretreatment: Organic waste gas first enters the pretreatment system, and through filtration, dehumidification, and other operations, impurities such as particulate matter and moisture are removed from the waste gas to protect subsequent equipment and improve treatment efficiency.

转轮吸附：预处理后的废气进入沸石转轮吸附区。沸石转轮是一种具有高效吸附性能的设备，其表面涂覆有沸石分子筛。在转轮转动过程中，废气中的有机污染物被沸石分子筛吸附，从而使废气得到净化。由于沸石转轮具有较大的比表面积和特殊的微孔结构，对有机废气有很强的吸附能力。

Rotary adsorption: The pre treated exhaust gas enters the zeolite rotary adsorption zone. Zeolite wheel is a device with efficient adsorption performance, and its surface is coated with zeolite molecular sieve. During the rotation of the wheel, organic pollutants in the exhaust gas are adsorbed by zeolite molecular sieves, thereby purifying the exhaust gas. Due to its large specific surface area and unique microporous structure, zeolite rotors have strong adsorption capacity for organic waste gases.

转轮脱附：随着转轮的转动，吸附饱和的部分进入脱附区。在脱附区，通过加热的方式使沸石分子筛上吸附的有机污染物解吸出来，形成高浓度的有机废气。通常采用热空气作为脱附介质，热空气的温度一般在 180 - 220℃左右。解吸出的高浓度有机废气被收集后送入 RTO 进行进一步处理。

Spin off: As the spin rotates, the saturated adsorption portion enters the desorption zone. In the desorption zone, the organic pollutants adsorbed on the zeolite molecular sieve are desorbed by heating, forming high concentration organic waste gas. Usually, hot air is used as the desorption medium, and the temperature of the hot air is generally around 180-220 ℃. The high concentration organic waste gas extracted is collected and sent to RTO for further treatment.

RTO 氧化处理

RTO oxidation treatment

废气预热：从沸石转轮脱附出来的高浓度有机废气进入 RTO 后，首先进入预热区。在预热区，废气与蓄热体进行热交换，蓄热体将上一周期氧化反应产生的热量传递给废气，使废气温度升高至接近反应温度。

Waste gas preheating: After the high concentration organic waste gas desorbed from the zeolite wheel enters the RTO, it first enters the preheating zone. In the preheating zone, the exhaust gas exchanges heat with the heat storage body, which transfers the heat generated by the oxidation reaction in the previous cycle to the exhaust gas, causing the exhaust gas temperature to rise to near the reaction temperature.

氧化反应：预热后的废气进入氧化室，在高温（一般为 750 - 850℃）和氧气的作用下，有机污染物发生氧化反应，生成二氧化碳和水等无害物质。氧化反应释放出大量的热量，使废气温度进一步升高。

Oxidation reaction: Preheated exhaust gas enters the oxidation chamber, and under the action of high temperature (usually 750-850 ℃) and oxygen, organic pollutants undergo oxidation reaction, generating harmless substances such as carbon dioxide and water. The oxidation reaction releases a large amount of heat, further increasing the temperature of the exhaust gas.

热量回收：氧化后的高温废气进入蓄热区，与蓄热体进行热交换，将热量传递给蓄热体，使蓄热体升温。废气自身温度则降低至接近室温后排出。蓄热体吸收的热量用于下一周期的废气预热，从而实现热量的循环利用，降低能耗。

Heat recovery: The oxidized high-temperature exhaust gas enters the heat storage area and exchanges heat with the heat storage body, transferring heat to the heat storage body and raising its temperature. The temperature of the exhaust gas itself decreases to near room temperature before being discharged. The heat absorbed by the thermal storage body is used for preheating the exhaust gas in the next cycle, thereby achieving the recycling of heat and reducing energy consumption.

通过沸石转轮的吸附浓缩和 RTO 的氧化处理，有机废气中的污染物被有效去除，同时在处理过程中实现了废气中热量的回收利用，提高了能源利用效率，降低了运行成本。

Through the adsorption concentration of zeolite wheels and the oxidation treatment of RTO, pollutants in organic waste gas are effectively removed, and the heat recovery and utilization in the waste gas are achieved during the treatment process, improving energy utilization efficiency and reducing operating costs.
