The zeolite runner+RTO combination process is currently the mainstream technology for treating low concentration and high air volume waste gas. The zeolite runner concentrates high air volume and low concentration waste gas into high concentration and low air volume waste gas, thereby reducing equipment investment and operating costs.

沸石转轮+RTO工艺原理如下：

The principle of zeolite runner+RTO process is as follows:

吸附阶段：有机废气经过沸石转轮吸附后直接达标排放，沸石分子筛由于孔径的大小能根据废气分子的大小和极性的不同进行选择性的吸附。即使废气成分的浓度很低仍具有较高的吸附能力，且在高温下扔具有很强的吸附能力，这是其他吸附剂不具备的。

Adsorption stage: Organic waste gas is directly discharged after being adsorbed by zeolite wheels, and zeolite molecular sieves can selectively adsorb according to the size and polarity of waste gas molecules due to their pore size. Even if the concentration of exhaust gas components is very low, it still has high adsorption capacity, and it has strong adsorption capacity at high temperatures, which is not possessed by other adsorbents.

脱附阶段：沸石转轮始终保持非常缓慢的旋转，在废气处理区吸附饱和，在再生区把吸附在沸石里的有机废气通过热空气吹扫下脱附出来。热空气的温度根据废气的成分而设定，沸石吸附更大的特点就是沸石不可燃，脱附时可保持较高的脱附温度因而可适用于很多沸点较高的废气成分，这一点是活性炭吸附+催化燃烧所达不到的。

Desorption stage: The zeolite wheel always maintains a very slow rotation, saturating the adsorption in the waste gas treatment zone, and desorbing the organic waste gas adsorbed in the zeolite through hot air blowing in the regeneration zone. The temperature of the hot air is set according to the composition of the exhaust gas. The greater characteristic of zeolite adsorption is that it is not combustible, and can maintain a high desorption temperature during desorption, making it suitable for many high boiling point exhaust gas components. This is not achieved by activated carbon adsorption+catalytic combustion.

RTO燃烧阶段：沸石转轮实际上是个浓缩装置，把低浓度大风量废气里的废气分子捕捉、富集到沸石上面。当脱附时就能用很小的热风从沸石中把废气分子吹扫出来。这时脱附出来的高浓度小风量的废气就可直接进入RTO蓄热焚烧炉进行高温焚烧。由于出来的废气浓度较高风量较小，所以RTO设备使用很低的辅助燃料就可以让废气得到较好的净化效果。

RTO combustion stage: The zeolite runner is actually a concentration device that captures and enriches exhaust gas molecules from low concentration and high airflow exhaust gas onto the zeolite. When desorbing, a small amount of hot air can be used to blow out the exhaust gas molecules from the zeolite. At this point, the high concentration and small air volume of the desorbed waste gas can directly enter the RTO thermal storage incinerator for high-temperature incineration. Due to the high concentration of exhaust gas and low air volume, RTO equipment can achieve good purification effects by using very low auxiliary fuel.

沸石转轮恢复阶段：沸石转轮脱附区经高温再生后会使得沸石温度很高，使吸附效果变差。因而要对经过高温吹扫过的沸石区域用补冷风机进行降温，降温后的沸石又具有吸附废气的能力，周而复始循环往复吸附废气。

Zeolite wheel recovery stage: After high-temperature regeneration of the zeolite wheel desorption zone, the zeolite temperature will be very high, resulting in poor adsorption effect. Therefore, it is necessary to use a supplementary cooling fan to cool the zeolite area that has undergone high-temperature blowing, and the cooled zeolite has the ability to adsorb waste gas, repeating the cycle of adsorbing waste gas.

沸石转轮+RTO组合工艺适用于化工、涂料、医药农药制造、电子产品制造、家具制造行业、包装印刷行业、涂装、涂布行业、饲料化肥等涉及有机溶剂使用和有机废气排放的所有行业。

The zeolite wheel+RTO combination process is suitable for all industries related to the use of organic solvents and organic waste gas emissions, such as chemical engineering, coatings, pharmaceutical pesticide manufacturing, electronic product manufacturing, furniture manufacturing, packaging and printing industry, painting, coating industry, feed and fertilizer industry.
