催化燃烧设备+沸石转轮浓缩废气处理技术用于处理低浓度VOCs、大风量工业废气的效率高、投资成本比以往更小。

The catalytic combustion equipment+zeolite rotary wheel concentration waste gas treatment technology is used to treat low concentration VOCs and high air volume industrial waste gas with high efficiency and lower investment costs than before.

吸附分离浓缩+催化燃烧分解净化法的基本思路是：采用吸附分离法对大风量、低浓度工业的有机废气VOCs进行分离浓缩，然后再对浓缩后的小风、量高浓度的有机废气进行催化燃烧分解净化。

The basic idea of adsorption separation concentration+catalytic combustion decomposition purification method is to use adsorption separation method to separate and concentrate VOCs from high air volume and low concentration industrial waste gas, and then perform catalytic combustion decomposition purification on the concentrated low air volume and high concentration organic waste gas.

建立吸附区旁路内循环：当废气经过吸附区吸附后不达标，进入旁路内循环，再次进行吸附处理。此旁路内循环的基本思路为消灭现有污染再吸纳新的污染。

Establish bypass circulation in the adsorption zone: When the exhaust gas does not meet the standard after being adsorbed in the adsorption zone, it enters the bypass circulation and undergoes adsorption treatment again. The basic idea of this bypass circulation is to eliminate existing pollution and absorb new pollution.

建立冷却风旁路：在工况复杂的情况下，VOCs浓度有可能陡然升高，此时将部分冷却风引入到吸附区以降低脱附风量，同时在传热②后补充新风，以维系进入催化反应器的风量在预设范围以内。此旁路的基本思路是以新风对高浓度VOCs进行稀释，因而从效果上看，此法也会延长治理时间。

Establish a cooling air bypass: In complex working conditions, the concentration of VOCs may suddenly increase. At this time, some cooling air is introduced into the adsorption zone to reduce the desorption air volume, and fresh air is supplemented after heat transfer to maintain the air volume entering the catalytic reactor within the preset range. The basic idea of this bypass is to dilute high concentration VOCs with fresh air, so from the perspective of effectiveness, this method will also extend the treatment time.

转轮转速易调：在②的情况下可以适当提高转轮转速，减少单位面积转轮单位时间内吸附VOCs的量，从而保障系统的持续稳定。

Adjustable wheel speed: In the case of ②, the wheel speed can be appropriately increased to reduce the amount of VOCs adsorbed per unit area and unit time of the wheel, thereby ensuring the continuous stability of the system.

催化燃烧室去掉电辅热系统，改为传热②对空气加热到VOCs起燃的温度，并利用反应放热使催化燃烧室温度稳定在500℃～600℃范围内。

Remove the electric auxiliary heating system from the catalytic combustion chamber and replace it with heat transfer. Heat the air to the temperature at which VOCs ignite, and use the heat released from the reaction to stabilize the temperature of the catalytic combustion chamber within the range of 500 ℃ to 600 ℃.

与传统工艺相比，该整个系统采用引风机设计，便于对旁路的调控。去掉给催化燃烧装置用的降温鼓风机（此机治标不治本）改为在转轮部分控制VOCs浓度。

Compared with traditional processes, the entire system adopts an induced draft fan design, which facilitates the regulation of the bypass. Remove the cooling blower used for the catalytic combustion device (which only treats the symptoms but not the root cause) and switch to controlling the concentration of VOCs in the rotor section.

废气处理催化燃烧设备的技术状况分析：蜂窝转轮吸附+催化燃烧处理技术是由日本发明的一种有机废气处理系统.其中吸附装置是用分子筛、活性碳纤维或含碳材料制备的瓦楞型纸板组装起来的蜂窝转轮，吸附与脱附气流的流向相反，两个过程同时进行。这种在系统被我国引进和仿制，但由于蜂窝转轮以及关键部位技术不过关，一直没有广泛使用。

Technical status analysis of catalytic combustion equipment for exhaust gas treatment: Honeycomb wheel adsorption+catalytic combustion treatment technology is an organic exhaust gas treatment system invented by Japan The adsorption device is a honeycomb wheel assembled from corrugated cardboard made of molecular sieves, activated carbon fibers, or carbon containing materials. The adsorption and desorption airflow directions are opposite, and the two processes are carried out simultaneously. This type of system has been introduced and replicated in China, but has not been widely used due to the inadequate technology of honeycomb wheels and key components.
