廢氣預(yù)處理：有機(jī)廢氣首先進(jìn)入預(yù)處理系統(tǒng)，通過(guò)過(guò)濾、除濕等操作，去除廢氣中的顆粒物、水分等雜質(zhì)，以保護(hù)后續(xù)設(shè)備并提高處理效率。

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.

轉(zhuǎn)輪吸附：預(yù)處理后的廢氣進(jìn)入沸石轉(zhuǎn)輪吸附區(qū)。沸石轉(zhuǎn)輪是一種具有高效吸附性能的設(shè)備，其表面涂覆有沸石分子篩。在轉(zhuǎn)輪轉(zhuǎn)動(dòng)過(guò)程中，廢氣中的有機(jī)污染物被沸石分子篩吸附，從而使廢氣得到凈化。由于沸石轉(zhuǎn)輪具有較大的比表面積和特殊的微孔結(jié)構(gòu)，對(duì)有機(jī)廢氣有很強(qiáng)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.

轉(zhuǎn)輪脫附：隨著轉(zhuǎn)輪的轉(zhuǎn)動(dòng)，吸附飽和的部分進(jìn)入脫附區(qū)。在脫附區(qū)，通過(guò)加熱的方式使沸石分子篩上吸附的有機(jī)污染物解吸出來(lái)，形成高濃度的有機(jī)廢氣。通常采用熱空氣作為脫附介質(zhì)，熱空氣的溫度一般在 180 - 220℃左右。解吸出的高濃度有機(jī)廢氣被收集后送入 RTO 進(jìn)行進(jìn)一步處理。

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 氧化處理

RTO oxidation treatment

廢氣預(yù)熱：從沸石轉(zhuǎn)輪脫附出來(lái)的高濃度有機(jī)廢氣進(jìn)入 RTO 后，首先進(jìn)入預(yù)熱區(qū)。在預(yù)熱區(qū)，廢氣與蓄熱體進(jìn)行熱交換，蓄熱體將上一周期氧化反應(yīng)產(chǎn)生的熱量傳遞給廢氣，使廢氣溫度升高至接近反應(yīng)溫度。

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.

氧化反應(yīng)：預(yù)熱后的廢氣進(jìn)入氧化室，在高溫（一般為 750 - 850℃）和氧氣的作用下，有機(jī)污染物發(fā)生氧化反應(yīng)，生成二氧化碳和水等無(wú)害物質(zhì)。氧化反應(yīng)釋放出大量的熱量，使廢氣溫度進(jìn)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.

熱量回收：氧化后的高溫廢氣進(jìn)入蓄熱區(qū)，與蓄熱體進(jìn)行熱交換，將熱量傳遞給蓄熱體，使蓄熱體升溫。廢氣自身溫度則降低至接近室溫后排出。蓄熱體吸收的熱量用于下一周期的廢氣預(yù)熱，從而實(shí)現(xiàn)熱量的循環(huán)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.

通過(guò)沸石轉(zhuǎn)輪的吸附濃縮和 RTO 的氧化處理，有機(jī)廢氣中的污染物被有效去除，同時(shí)在處理過(guò)程中實(shí)現(xiàn)了廢氣中熱量的回收利用，提高了能源利用效率，降低了運(yùn)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.
