在工業(yè)發(fā)展的進(jìn)程中，揮發(fā)性有機(jī)化合物（VOCs）的排放成為了環(huán)境污染的重要源頭之一。VOCs 不僅會(huì)對(duì)大氣環(huán)境造成破壞，引發(fā)光化學(xué)煙霧等環(huán)境問(wèn)題，還會(huì)對(duì)人體健康產(chǎn)生嚴(yán)重威脅。為了有效治理 VOCs，各種廢氣處理技術(shù)應(yīng)運(yùn)而生，其中，沸石轉(zhuǎn)輪與 CO（催化氧化）的組合技術(shù)憑借其卓越的性能，成為了當(dāng)下廢氣處理領(lǐng)域的明星技術(shù)。

In the process of industrial development, the emission of volatile organic compounds (VOCs) has become one of the important sources of environmental pollution. VOCs not only cause damage to the atmospheric environment and lead to environmental problems such as photochemical smog, but also pose a serious threat to human health. In order to effectively control VOCs, various waste gas treatment technologies have emerged, among which the combination technology of zeolite impeller and CO (catalytic oxidation) has become a star technology in the current waste gas treatment field due to its excellent performance.

一、沸石轉(zhuǎn)輪：高效的吸附能手

1、 Zeolite Wheel: Efficient Adsorption Expert

沸石轉(zhuǎn)輪是根據(jù)沸石分子篩的吸附和脫附原理專門設(shè)計(jì)用于處理廢氣的設(shè)備 ，其結(jié)構(gòu)獨(dú)特，內(nèi)部為蜂窩狀，由沸石材料制成，擁有大量微孔 。這些微孔賦予了沸石轉(zhuǎn)輪強(qiáng)大的吸附能力，能夠高效吸附廢氣中的 VOCs。

Zeolite wheel is a device specially designed for treating exhaust gas based on the adsorption and desorption principles of zeolite molecular sieves. Its unique structure is honeycomb shaped inside, made of zeolite material, and has a large number of micropores. These micropores endow the zeolite wheel with strong adsorption capacity, enabling efficient adsorption of VOCs in exhaust gas.

沸石轉(zhuǎn)輪的工作過(guò)程主要分為三個(gè)區(qū)域：吸附區(qū)、脫附區(qū)和冷卻區(qū)。在吸附區(qū)，當(dāng)廢氣通過(guò)沸石轉(zhuǎn)輪時(shí)，其中的 VOCs 被吸附在沸石的微孔中，實(shí)現(xiàn)廢氣的初步凈化，凈化后的廢氣排空。隨著轉(zhuǎn)輪的轉(zhuǎn)動(dòng)，吸附飽和的部分進(jìn)入脫附區(qū)，通過(guò)加熱解吸的方式，使吸附在沸石上的 VOCs 脫附下來(lái)，此時(shí)脫附后的氣體濃度得到大幅濃縮 。解吸后的轉(zhuǎn)輪進(jìn)入冷卻區(qū)，小部分廢氣送入冷卻區(qū)給轉(zhuǎn)輪降溫，使其恢復(fù)吸附能力，冷卻后的空氣加熱至一定溫度后又作為脫附空氣進(jìn)入脫附區(qū)，形成循環(huán)，實(shí)現(xiàn)節(jié)能。沸石轉(zhuǎn)輪具有諸多優(yōu)點(diǎn)，它的吸附效率高，能達(dá)到 95% 以上 ，可以實(shí)現(xiàn) 5 - 15 倍甚至更高的濃縮倍數(shù) ，這不僅大大減小了后續(xù)處理設(shè)備的規(guī)模，還降低了成本。其吸附過(guò)程產(chǎn)生的壓降較低，電力消耗大幅減少，運(yùn)行費(fèi)用低 。而且，它采用模塊化設(shè)計(jì)，操作簡(jiǎn)便，維護(hù)也相對(duì)容易 。

The working process of zeolite wheel is mainly divided into three zones: adsorption zone, desorption zone, and cooling zone. In the adsorption zone, when the exhaust gas passes through the zeolite wheel, the VOCs are adsorbed in the micropores of the zeolite, achieving preliminary purification of the exhaust gas, and the purified exhaust gas is discharged. As the wheel rotates, the saturated adsorption part enters the desorption zone, and the VOCs adsorbed on the zeolite are desorbed by heating, resulting in a significant concentration of the desorbed gas. After desorption, the impeller enters the cooling zone, and a small portion of the exhaust gas is sent to the cooling zone to cool the impeller and restore its adsorption capacity. The cooled air is heated to a certain temperature and then used as desorption air to enter the desorption zone, forming a cycle and achieving energy saving. Zeolite rotary wheels have many advantages, such as high adsorption efficiency of over 95%, which can achieve concentration ratios of 5-15 times or even higher. This not only greatly reduces the scale of subsequent treatment equipment, but also lowers costs. The pressure drop generated during its adsorption process is relatively low, power consumption is significantly reduced, and operating costs are low. Moreover, it adopts a modular design, which is easy to operate and relatively easy to maintain.

二、CO 催化氧化：徹底的凈化力量

2、 CO catalytic oxidation: a thorough purification power

CO 催化氧化，即催化燃燒，是在催化劑的作用下，使 VOCs 與空氣中的氧氣發(fā)生氧化反應(yīng)，生成無(wú)害的二氧化碳和水 。這一過(guò)程能夠?qū)?VOCs 徹底轉(zhuǎn)化為無(wú)害物質(zhì)，實(shí)現(xiàn)高效凈化。

CO catalytic oxidation, also known as catalytic combustion, involves the oxidation reaction between VOCs and oxygen in the air under the action of a catalyst, producing harmless carbon dioxide and water. This process can thoroughly convert VOCs into harmless substances, achieving efficient purification.

在 CO 催化氧化過(guò)程中，催化劑是核心要素。常見(jiàn)的催化劑有貴金屬催化劑（如鉑、鈀等）和非貴金屬催化劑 。貴金屬催化劑具有活性高、起燃溫度低等優(yōu)點(diǎn)，能夠在較低的溫度（通常 300 - 400℃）下使 VOCs 發(fā)生氧化反應(yīng) ，大大降低了能耗和運(yùn)行成本 。非貴金屬催化劑則具有成本較低的優(yōu)勢(shì)，在一些對(duì)成本控制較為嚴(yán)格的場(chǎng)景中也有應(yīng)用。CO 催化氧化反應(yīng)效率高，能夠使廢氣中的 VOCs 得到深度凈化，滿足嚴(yán)格的環(huán)保排放標(biāo)準(zhǔn)。而且，由于反應(yīng)溫度相對(duì)較低，減少了氮氧化物等二次污染物的產(chǎn)生，更加環(huán)保。

In the process of CO catalytic oxidation, the catalyst is the core element. Common catalysts include precious metal catalysts (such as platinum, palladium, etc.) and non precious metal catalysts. Precious metal catalysts have the advantages of high activity and low ignition temperature, which can oxidize VOCs at lower temperatures (usually 300-400 ℃), greatly reducing energy consumption and operating costs. Non precious metal catalysts have the advantage of lower cost and are also applied in some scenarios with strict cost control. The CO catalytic oxidation reaction has high efficiency and can deeply purify VOCs in exhaust gas, meeting strict environmental emission standards. Moreover, due to the relatively low reaction temperature, the production of secondary pollutants such as nitrogen oxides is reduced, making it more environmentally friendly.

三、沸石轉(zhuǎn)輪 + CO：強(qiáng)強(qiáng)聯(lián)合，優(yōu)勢(shì)盡顯

3、 Zeolite wheel+CO: Strong combination, advantages fully demonstrated

將沸石轉(zhuǎn)輪與 CO 催化氧化結(jié)合，形成了一套高效的廢氣處理系統(tǒng)。沸石轉(zhuǎn)輪先對(duì)大風(fēng)量、低濃度的有機(jī)廢氣進(jìn)行吸附濃縮，將低濃度的 VOCs 富集起來(lái)，形成高濃度的氣體，然后送入 CO 反應(yīng)器進(jìn)行催化氧化 。這種組合方式充分發(fā)揮了兩者的優(yōu)勢(shì)。

The combination of zeolite impeller and CO catalytic oxidation forms an efficient exhaust gas treatment system. The zeolite wheel first adsorbs and concentrates high air volume and low concentration organic waste gas, enriching low concentration VOCs to form high concentration gas, which is then sent to the CO reactor for catalytic oxidation. This combination fully leverages the advantages of both.

處理效率極高，對(duì)于大風(fēng)量、低濃度的有機(jī)廢氣，單一的處理方式往往難以達(dá)到理想效果，而沸石轉(zhuǎn)輪 + CO 系統(tǒng)能夠?qū)崿F(xiàn)對(duì)這類廢氣的高效吸附和深度凈化，滿足各種嚴(yán)格的廢氣處理需求 。系統(tǒng)設(shè)計(jì)緊湊，占地面積小 ，這對(duì)于一些場(chǎng)地有限的企業(yè)來(lái)說(shuō)非常重要，能夠有效節(jié)省空間。其采用先進(jìn)的自動(dòng)化控制系統(tǒng)，不僅操作簡(jiǎn)便，還配備了故障預(yù)警系統(tǒng)，大大提高了設(shè)備運(yùn)行的安全性和穩(wěn)定性 。沸石轉(zhuǎn)輪 + CO 一體機(jī)在節(jié)能環(huán)保方面表現(xiàn)出色，一方面，沸石轉(zhuǎn)輪的吸附過(guò)程能耗低，另一方面，CO 催化氧化在相對(duì)較低的溫度下進(jìn)行，減少了能源消耗，且整個(gè)處理過(guò)程不產(chǎn)生二次污染 。

The processing efficiency is extremely high. For organic waste gases with high air volume and low concentration, a single treatment method is often difficult to achieve ideal results. However, the zeolite wheel+CO system can achieve efficient adsorption and deep purification of such waste gases, meeting various strict waste gas treatment requirements. The system design is compact and occupies a small area, which is very important for some enterprises with limited space and can effectively save space. It adopts advanced automation control system, which is not only easy to operate, but also equipped with fault warning system, greatly improving the safety and stability of equipment operation. The zeolite wheel+CO integrated machine performs well in energy conservation and environmental protection. On the one hand, the adsorption process of zeolite wheel has low energy consumption. On the other hand, CO catalytic oxidation is carried out at relatively low temperatures, reducing energy consumption and the entire treatment process does not produce secondary pollution.

四、廣泛的行業(yè)應(yīng)用

4、 Wide range of industry applications

沸石轉(zhuǎn)輪 + CO 一體機(jī)在眾多行業(yè)中都有廣泛應(yīng)用。在噴漆、汽車噴漆制造行業(yè)，噴漆過(guò)程中會(huì)產(chǎn)生大量含有苯系物、醇類、酮類等 VOCs 的廢氣 ，通過(guò)沸石轉(zhuǎn)輪 + CO 系統(tǒng)處理，能夠有效凈化廢氣，減少對(duì)環(huán)境的污染 。印刷、油墨印染行業(yè)，廢氣成分復(fù)雜，含有多種揮發(fā)性有機(jī)物，該系統(tǒng)也能發(fā)揮其高效處理的優(yōu)勢(shì)，確保廢氣達(dá)標(biāo)排放 。在化工、注塑、涂布等行業(yè)，同樣能高效去除廢氣中的 VOCs，保護(hù)生產(chǎn)環(huán)境和員工的身體健康 。此外，在電子產(chǎn)品制造、半導(dǎo)體制造等行業(yè)，由于對(duì)生產(chǎn)環(huán)境要求較高，沸石轉(zhuǎn)輪 + CO 一體機(jī)能夠有效改善車間內(nèi)空氣質(zhì)量，保障生產(chǎn)的順利進(jìn)行 。

Zeolite rotary wheel+CO integrated machine is widely used in many industries. In the spray painting and automotive spray painting manufacturing industries, a large amount of waste gas containing VOCs such as benzene derivatives, alcohols, and ketones is generated during the spray painting process. By treating the waste gas with a zeolite wheel and CO system, it can effectively purify the waste gas and reduce environmental pollution. In the printing and ink printing and dyeing industry, the exhaust gas composition is complex and contains various volatile organic compounds. This system can also leverage its efficient treatment advantages to ensure that the exhaust gas meets the emission standards. In industries such as chemical, injection molding, and coating, VOCs in exhaust gases can also be efficiently removed, protecting the production environment and the health of employees. In addition, in industries such as electronic product manufacturing and semiconductor manufacturing, due to the high requirements for the production environment, the zeolite wheel+CO integrated machine can effectively improve the air quality in the workshop and ensure the smooth progress of production.

With the increasingly strict environmental requirements, the demand for VOCs treatment technology is also constantly increasing. The zeolite wheel+CO technology, with its significant advantages, has broad market prospects in the future. However, this technology also faces some challenges. The investment cost of equipment is relatively high, and for some small and medium-sized enterprises, there may be financial pressure. The operation and maintenance require professional technical personnel, which puts forward requirements for the talent reserve and technical training of the enterprise. The composition and working conditions of exhaust gases generated by different industries vary greatly. How to further optimize technology to better adapt to various complex exhaust gas treatment needs is also a problem that needs to be solved.
