技术概况：采用沸石转轮吸附浓缩法对低浓度、大风量工业废气中的VOCs进行浓缩，对浓缩后的高浓度、小风量的污染空气采用RTO蓄热式氧化法进行分解净化。

Technical Overview: The zeolite rotary adsorption concentration method is used to concentrate VOCs in low concentration and high air volume industrial waste gas. The concentrated high concentration and low air volume polluted air is decomposed and purified using RTO thermal storage oxidation method.

沸石转轮+rto该技术的基本构思是：

The basic concept of zeolite wheel+RTO technology is:

含有VOCs 的污染空气由鼓风机送到沸石转轮的吸附区，污染空气在通过沸石转轮蜂窝状通道时，所含VOCs成分被吸附剂所吸附，空气得到净化。

Polluted air containing VOCs is sent by a blower to the adsorption area of the zeolite wheel. When the polluted air passes through the honeycomb channel of the zeolite wheel, the VOCs content is adsorbed by the adsorbent, and the air is purified.

随着吸附转轮的回转，接近吸附饱和状态的吸附转轮进入到再生区，在与180℃ -220 ℃高温脱附再生空气接触的过程中，VOCs被脱附下来进入到再生空气中，沸石转轮得到再生。

As the adsorption wheel rotates, the adsorption wheel approaching saturation enters the regeneration zone. During the process of contact with the high-temperature desorption regeneration air at 180 ℃ -220 ℃, VOCs are desorbed and enter the regeneration air, and the zeolite wheel is regenerated.

脱附后把大风量低浓度的有机废气浓缩成小风量高浓度的废气，再进入RTO蓄热式氧化炉设备，经过蓄热室升温吸热，离开蓄热室，进入氧化室，升到 800多 ℃的温度，焚烧氧化废气，使废气氧化分解成二氧化碳和水。释放的热量可回收到设备内循环使用，，节省能耗损失。

After desorption, the high air volume and low concentration organic waste gas is concentrated into low air volume and high concentration waste gas, which then enters the RTO thermal storage oxidation furnace equipment. After being heated and absorbed by the heat storage chamber, it leaves the storage chamber and enters the oxidation chamber, rising to a temperature of over 800 ℃. The oxidized waste gas is incinerated to oxidize and decompose into carbon dioxide and water. The heat released can be recycled and reused within the equipment, which is energy-saving, environmentally friendly, and saves energy losses.
