分子筛吸附浓缩转轮装置ZCR（Zeolite Concentrator Rotor），是20世纪70年代后期发展起来的，Napotec?分子筛吸附材料附着于蜂窝状多孔载体上制备而成的一种转动吸附设备。

The Zeolite Concentrator Rotary (ZCR), a molecular sieve adsorption and concentration device, was developed in the late 1970s by Napotec? A rotating adsorption device prepared by attaching molecular sieve adsorbent material onto a honeycomb porous carrier.

沸石分子筛转轮吸附浓缩系统利用吸附-脱附浓缩-冷却这一连续性过程，对VOCs废气进行吸附浓缩。其基本原理如下：

The zeolite molecular sieve rotary adsorption concentration system utilizes a continuous process of adsorption desorption concentration cooling to adsorb and concentrate VOCs waste gas. The basic principle is as follows:

1.沸石分子筛转轮分为吸附区、脱附区和冷却区三个功能区域，沸石分子筛转轮在各个功能区域内连续运转。

1. The zeolite molecular sieve wheel is divided into three functional areas: adsorption area, desorption area, and cooling area. The zeolite molecular sieve wheel operates continuously in each functional area.

2.废气通过前置的过滤器后，送至沸石分子筛转轮的吸附区。在吸附区（吸附区面积为S1）有机废气中VOCs被沸石分子筛吸附除去，有机废气被净化后从沸石分子筛转轮处理区排出。

2. After passing through the pre filter, the exhaust gas is sent to the adsorption area of the zeolite molecular sieve wheel. VOCs in organic waste gas are adsorbed and removed by zeolite molecular sieves in the adsorption zone (with an adsorption area of S1), and the organic waste gas is purified and discharged from the zeolite molecular sieve rotary processing area.

3.吸附在分子筛转轮中的VOCs，在脱附区（脱附区面积为S2）经过约220℃小风量的热风处理而被脱附、浓缩，浓缩倍数一般为5~25倍。

3. The VOCs adsorbed in the molecular sieve impeller are desorbed and concentrated in the desorption zone (with an area of S2) after a small amount of hot air treatment at about 220 ℃, with a concentration factor of generally 5-25 times.

浓缩倍数n=( S1×V1)/ (S2×V2)），其中S1/S2=10:1，V1/V2=(0.5~2.5)

Concentration ratio n=(S1 x V1)/(S2 x V2), where S1/S2=10:1 and V1/V2=(0.5-2.5)

4.再生后的沸石分子筛转轮在冷却区被冷却。经过冷却区的空气，经过加热后作为再生空气使用，达到节能的效果。

4. The regenerated zeolite molecular sieve wheel is cooled in the cooling zone. The air passing through the cooling zone is heated and used as regenerated air to achieve energy-saving effects.
