在工业生产活动日益频繁的当下，废气排放带来的环境问题愈发严峻。为了实现绿色发展，保障生态环境质量，高效的废气处理技术成为了众多企业关注的焦点。其中，沸石转轮与 CO（催化燃烧）组合的废气处理系统，以其卓越的性能，在众多处理工艺中脱颖而出，成为了应对挥发性有机化合物（VOCs）等废气污染的有力武器。​

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). ​

沸石转轮：废气预处理的核心环节​

Zeolite wheel: the core link of exhaust gas pretreatment

沸石转轮本质上是一种吸附浓缩装置，其工作原理基于沸石分子筛独特的吸附性能。沸石转轮由吸附区、脱附区和冷却区三个功能区域组成，整体呈圆盘状并可缓慢旋转。当含有 VOCs 的废气通过吸附区时，沸石分子筛凭借其巨大的比表面积和丰富的微孔结构，能够高效地将废气中的有机污染物吸附在自身表面。随着转轮的转动，吸附饱和的区域进入脱附区。在脱附区，通过引入高温热风，使得被吸附的 VOCs 从沸石分子筛表面脱附出来，从而实现沸石转轮的再生。脱附后的高浓度废气被收集起来，进入后续的处理环节。而经过脱附后的转轮区域，再进入冷却区进行降温冷却，恢复到初始的吸附活性，以便重新投入吸附工作。整个过程周而复始，持续不断地对废气进行吸附浓缩预处理。​

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. ​

沸石转轮具有诸多显著优势。其一，吸附效率高，对多种 VOCs 都能达到 80% - 95% 甚至更高的吸附率。其二，处理风量大，能够适应大规模工业废气排放的处理需求。其三，其结构紧凑，占地面积小，相比其他一些吸附设备，更适合在空间有限的工厂环境中安装使用。

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.
