在工業(yè)生產(chǎn)活動(dòng)日益頻繁的當(dāng)下，廢氣排放帶來(lái)的環(huán)境問(wèn)題愈發(fā)嚴(yán)峻。為了實(shí)現(xiàn)綠色發(fā)展，保障生態(tài)環(huán)境質(zhì)量，高效的廢氣處理技術(shù)成為了眾多企業(yè)關(guān)注的焦點(diǎn)。其中，沸石轉(zhuǎn)輪與 CO（催化燃燒）組合的廢氣處理系統(tǒng)，以其卓越的性能，在眾多處理工藝中脫穎而出，成為了應(yīng)對(duì)揮發(fā)性有機(jī)化合物（VOCs）等廢氣污染的有力武器。?
In the increasingly frequent industrial production activities, the environmental problems caused by exhaust emissions are becoming more severe. In order to achieve green development and ensure the quality of the ecological environment, efficient waste gas treatment technology has become a focus of attention for many enterprises. Among them, the exhaust gas treatment system combining zeolite impeller and CO (catalytic combustion) stands out among many treatment processes due to its excellent performance, becoming a powerful weapon for dealing with exhaust gas pollution such as volatile organic compounds (VOCs). ?

Zeolite wheel: the core link of exhaust gas pretreatment
沸石轉(zhuǎn)輪本質(zhì)上是一種吸附濃縮裝置，其工作原理基于沸石分子篩獨(dú)特的吸附性能。沸石轉(zhuǎn)輪由吸附區(qū)、脫附區(qū)和冷卻區(qū)三個(gè)功能區(qū)域組成，整體呈圓盤(pán)狀并可緩慢旋轉(zhuǎn)。當(dāng)含有 VOCs 的廢氣通過(guò)吸附區(qū)時(shí)，沸石分子篩憑借其巨大的比表面積和豐富的微孔結(jié)構(gòu)，能夠高效地將廢氣中的有機(jī)污染物吸附在自身表面。隨著轉(zhuǎn)輪的轉(zhuǎn)動(dòng)，吸附飽和的區(qū)域進(jìn)入脫附區(qū)。在脫附區(qū)，通過(guò)引入高溫?zé)犸L(fēng)，使得被吸附的 VOCs 從沸石分子篩表面脫附出來(lái)，從而實(shí)現(xiàn)沸石轉(zhuǎn)輪的再生。脫附后的高濃度廢氣被收集起來(lái)，進(jìn)入后續(xù)的處理環(huán)節(jié)。而經(jīng)過(guò)脫附后的轉(zhuǎn)輪區(qū)域，再進(jìn)入冷卻區(qū)進(jìn)行降溫冷卻，恢復(fù)到初始的吸附活性，以便重新投入吸附工作。整個(gè)過(guò)程周而復(fù)始，持續(xù)不斷地對(duì)廢氣進(jìn)行吸附濃縮預(yù)處理。?
The zeolite wheel is essentially an adsorption concentration device, and its working principle is based on the unique adsorption performance of zeolite molecular sieves. The zeolite wheel consists of three functional areas: adsorption zone, desorption zone, and cooling zone, and is shaped like a disk and can rotate slowly. When exhaust gas containing VOCs passes through the adsorption zone, zeolite molecular sieves, with their huge specific surface area and rich microporous structure, can efficiently adsorb organic pollutants in the exhaust gas onto their own surface. As the wheel rotates, the adsorption saturated region enters the desorption zone. In the desorption zone, high-temperature hot air is introduced to desorb the adsorbed VOCs from the surface of the zeolite molecular sieve, thereby achieving the regeneration of the zeolite wheel. The high concentration exhaust gas after desorption is collected and enters the subsequent treatment process. After detachment, the rotating wheel area enters the cooling zone for cooling and restoration of initial adsorption activity, in order to resume adsorption work. The entire process repeats itself, continuously adsorbing, concentrating, and pre treating the exhaust gas. ?
沸石轉(zhuǎn)輪具有諸多顯著優(yōu)勢(shì)。其一，吸附效率高，對(duì)多種 VOCs 都能達(dá)到 80% - 95% 甚至更高的吸附率。其二，處理風(fēng)量大，能夠適應(yīng)大規(guī)模工業(yè)廢氣排放的處理需求。其三，其結(jié)構(gòu)緊湊，占地面積小，相比其他一些吸附設(shè)備，更適合在空間有限的工廠(chǎng)環(huán)境中安裝使用。
Zeolite wheels have many significant advantages. Firstly, it has high adsorption efficiency and can achieve adsorption rates of 80% -95% or even higher for various VOCs. Secondly, the processing air volume is large, which can meet the treatment needs of large-scale industrial waste gas emissions. Thirdly, its compact structure and small footprint make it more suitable for installation and use in factory environments with limited space compared to other adsorption equipment.
