The combination of zeolite molecular sieve wheels is a central bearing and a rotating body, which is one of the relatively complete equipment for adsorption, desorption, and concentration incineration. It has many advantages over honeycomb activated carbon in terms of adsorption process, but the adsorption performance of zeolite is much greater than that of activated carbon, such as the removal of formaldehyde. The basic service life of activated carbon adsorption is less than one year, It is easy to adsorb and saturate, and it needs to be replaced regularly. The service life of zeolite rotary molecular sieve can reach more than 10 years, greatly reducing the cost and frequency of replacement, and reducing the expenditure on manpower and material resources. The one-time investment returns such as safety and continuity efficiency can last for decades. Moreover, the organic VOC gas concentration and efficiency in the desorption and catalytic combustion stages are higher. So zeolite molecular sieve wheels are increasingly being used in the treatment of organic waste gas.

沸石分子筛的工艺原理运行方式：

The process principle and operation mode of zeolite molecular sieve:

沸石分子筛吸附浓缩转轮密封系统分为处理区，再生区和冷却区三个部分，转轮缓慢旋转（1~6r/h）使各个区内吸附过程完整连续运转。当VOCs有机废气通过前置处理区时，其中的有机废气成分被转轮中的吸附剂所吸附去除，废气被净化后的空气从浓缩转轮的处理区间而排空，转轮逐渐达到吸附饱和。同时在再生区高温下空气通过吸附饱和，废气被吸附脱附后由经高温空气排走，达到连续去除VOCs效果的同时也恢复转轮的吸附能力提高废气浓度，脱附的高温气体进入RTO/CO氧化装置便于进行氧化处理。

The sealing system of the zeolite molecular sieve adsorption and concentration rotary wheel is divided into three parts: the treatment zone, the regeneration zone, and the cooling zone. The rotary wheel slowly rotates (1-6r/h) to ensure the complete and continuous operation of the adsorption process in each zone. When VOCs organic waste gas passes through the pre-treatment zone, the organic waste gas components are adsorbed and removed by the adsorbent in the runner. The purified air in the waste gas is discharged from the treatment zone of the concentration runner, and the runner gradually reaches adsorption saturation. At the same time, at high temperatures in the regeneration zone, the air is saturated through adsorption, and the waste gas is adsorbed and desorbed before being discharged through high-temperature air, achieving continuous removal of VOCs while also restoring the adsorption capacity of the runner to improve the concentration of waste gas. The desorbed high-temperature gas enters the RTO/CO oxidation device for easy oxygenation treatment.
