在工業(yè)生產(chǎn)過程中，揮發(fā)性有機(jī)化合物（VOCs）廢氣的排放是一個(gè)嚴(yán)重的環(huán)境問題。這些廢氣不僅會(huì)對(duì)空氣質(zhì)量造成污染，還可能危害人體健康。沸石轉(zhuǎn)輪廢氣處理技術(shù)作為一種高效、節(jié)能的 VOCs 治理方法，正逐漸成為工業(yè)廢氣凈化領(lǐng)域的關(guān)鍵技術(shù)。

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

沸石轉(zhuǎn)輪廢氣處理技術(shù)的核心在于利用沸石的吸附特性。沸石是一種具有多孔結(jié)構(gòu)的硅鋁酸鹽礦物質(zhì)，其內(nèi)部擁有大量均勻且微小的孔徑，比表面積大，這使得沸石對(duì) VOCs 具有很強(qiáng)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.

沸石轉(zhuǎn)輪通常被劃分為吸附區(qū)、脫附區(qū)和冷卻區(qū)三個(gè)功能區(qū)域。當(dāng)含有 VOCs 的廢氣在風(fēng)機(jī)的作用下進(jìn)入吸附區(qū)時(shí)，廢氣中的 VOCs 分子被沸石轉(zhuǎn)輪上的沸石吸附，從而實(shí)現(xiàn)廢氣的初步凈化。隨著沸石轉(zhuǎn)輪的緩慢轉(zhuǎn)動(dòng)，吸附飽和的沸石區(qū)域進(jìn)入脫附區(qū)。在脫附區(qū)，通過引入高溫?zé)犸L(fēng)，使沸石上吸附的 VOCs 分子受熱脫附，形成高濃度的 VOCs 廢氣。脫附后的沸石轉(zhuǎn)輪進(jìn)入冷卻區(qū)，被冷卻至適宜的吸附溫度，以便再次進(jìn)入吸附區(qū)進(jìn)行吸附工作，如此循環(huán)往復(fù)。

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.

脫附出來的高濃度 VOCs 廢氣，后續(xù)通常會(huì)進(jìn)入燃燒設(shè)備（如 RTO、RCO 等）進(jìn)行進(jìn)一步處理，在高溫下被分解為二氧化碳和水等無害物質(zhì)，最終達(dá)標(biāo)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、系統(tǒng)組成

2、 System composition

沸石轉(zhuǎn)輪：這是整個(gè)系統(tǒng)的核心部件，由涂覆有沸石的陶瓷纖維紙卷制而成，呈蜂窩狀結(jié)構(gòu)，具有較大的比表面積和良好的吸附性能。

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.

廢氣預(yù)處理裝置：為了保護(hù)沸石轉(zhuǎn)輪，延長其使用壽命，在廢氣進(jìn)入沸石轉(zhuǎn)輪之前，需要進(jìn)行預(yù)處理。預(yù)處理裝置通常包括過濾器、冷凝器等，用于去除廢氣中的顆粒物、水分和粘性物質(zhì)等雜質(zhì)。

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.

熱風(fēng)循環(huán)系統(tǒng)：主要用于提供脫附所需的高溫?zé)犸L(fēng)。該系統(tǒng)包括加熱器、風(fēng)機(jī)、管道等組件，通過控制熱風(fēng)的溫度、流量和流向，確保沸石轉(zhuǎn)輪的脫附過程高效穩(wěn)定進(jìn)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.

燃燒裝置：用于處理脫附出來的高濃度 VOCs 廢氣。常見的燃燒裝置有蓄熱式熱力焚燒爐（RTO）和蓄熱式催化燃燒爐（RCO）。RTO 利用陶瓷蓄熱體儲(chǔ)存熱量，使廢氣在高溫下充分燃燒；RCO 則在催化劑的作用下，降低燃燒溫度，實(shí)現(xiàn) VOCs 的低溫燃燒，減少能源消耗。

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.

3、 Technical advantages

高效吸附：沸石轉(zhuǎn)輪對(duì) VOCs 具有較高的吸附效率，能夠有效去除廢氣中的多種有機(jī)污染物，如苯、甲苯、二甲苯、酯類、醇類等，凈化效率可達(dá) 90% 以上。

Efficient adsorption: Zeolite wheels have a high adsorption efficiency for VOCs, which can effectively remove various organic pollutants in exhaust gas, such as benzene, toluene, xylene, esters, alcohols, etc., with a purification efficiency of over 90%.

濃縮倍數(shù)高：可以將低濃度、大風(fēng)量的 VOCs 廢氣濃縮成高濃度、小風(fēng)量的廢氣，濃縮倍數(shù)通常在 5 - 20 倍之間，大大降低了后續(xù)燃燒處理的成本和能耗。

High concentration factor: Low concentration and high air volume VOCs waste gas can be concentrated into high concentration and low air volume waste gas, with a concentration factor usually between 5-20 times, greatly reducing the cost and energy consumption of subsequent combustion treatment.

能耗低：相比傳統(tǒng)的直接燃燒法或活性炭吸附法，沸石轉(zhuǎn)輪廢氣處理技術(shù)的能耗顯著降低。這是因?yàn)槠涿摳竭^程只需較低的溫度，且濃縮后的廢氣量減少，使得燃燒設(shè)備的能耗也相應(yīng)降低。

Low energy consumption: Compared to traditional direct combustion or activated carbon adsorption methods, zeolite rotary exhaust gas treatment technology significantly reduces energy consumption. This is because its desorption process only requires lower temperatures, and the amount of concentrated exhaust gas is reduced, resulting in a corresponding decrease in energy consumption of the combustion equipment.

穩(wěn)定性好：沸石轉(zhuǎn)輪具有良好的化學(xué)穩(wěn)定性和熱穩(wěn)定性，使用壽命長，能夠在較為惡劣的工況條件下穩(wěn)定運(yùn)行，減少了設(shè)備的維護(hù)和更換成本。

Good stability: Zeolite wheels have good chemical and thermal stability, long service life, and can operate stably under harsh working conditions, reducing equipment maintenance and replacement costs.

占地面積?。合到y(tǒng)采用模塊化設(shè)計(jì)，結(jié)構(gòu)緊湊，占地面積小，適用于場地空間有限的工業(yè)企業(yè)。
