沸石转轮吸附浓缩装置采用吸附-脱附-浓缩焚化三项连续程序，主要用于有机废气的治理； 特别适合于大风量，低浓度场合。该吸附装置以陶瓷纤维为基材，做成蜂窝状的大圆盘轮状系统， 轮子表面涂覆疏水性沸石做吸附剂。沸石转轮吸附浓缩装置主要由废气预处理系统、分子筛转轮浓 缩吸附系统、脱附系统、冷却干燥系统和自动控制系统等组成。转轮后一般有后处理系统。
The zeolite rotary adsorption concentration device adopts three continuous processes of adsorption desorption concentration incineration, mainly used for the treatment of organic waste gas; Especially suitable for high air volume and low concentration situations. The adsorption device is made of ceramic fibers as the substrate, forming a honeycomb shaped large disk wheel system, and the surface of the wheel is coated with hydrophobic zeolite as an adsorbent. The zeolite rotary adsorption and concentration device mainly consists of a waste gas pretreatment system, a molecular sieve rotary concentration and adsorption system, a desorption system, a cooling and drying system, and an automatic control system. After the wheel is rotated, there is usually a post-processing system.
Principle of Zeolite Rotary Wheel Adsorption and Concentration
沸石转轮主体为一个装满吸附剂的旋转轮，其被划分为3个区域，即吸附区、再生区和冷却区。有机 废气经鼓风机引入吸附区，其中的有机污染物被吸附，气体得到净化排出。随后，吸附剂转动到再 生区，在与高温空气接触的过程中，VOCS被脱附下来并随再生空气流出，同时吸附剂获得再生。 再生后的吸附剂先经过冷却区降温，然后转动到吸附区重新进行吸附。随着转轮的转动，吸附剂周 期性地进行吸附、脱附和冷却，实现对有机废气的净化。
The main body of the zeolite wheel is a rotating wheel filled with adsorbent, which is divided into three areas, namely the adsorption zone, regeneration zone, and cooling zone. The organic waste gas is introduced into the adsorption zone through a blower, where the organic pollutants are adsorbed and the gas is purified and discharged. Subsequently, the adsorbent rotates to the regeneration zone, and during contact with high-temperature air, VOCS is desorbed and flows out with the regenerated air, while the adsorbent undergoes regeneration. The regenerated adsorbent first passes through the cooling zone to cool down, and then rotates to the adsorption zone for re adsorption. As the wheel rotates, the adsorbent periodically adsorbs, desorbs, and cools to achieve the purification of organic waste gas.
1. High adsorption and desorption efficiency.
2. The pressure drop generated by the adsorption of VOCS by zeolite wheels is extremely low, which can greatly reduce power consumption.
3. Transforming the originally high air volume and low concentration VOCS exhaust gas into low air volume and high concentration exhaust gas, the concentration factor can reach 5-20 times, greatly reducing the specifications of the post-treatment equipment and reducing operating costs.
4. The overall system adopts modular design, with minimal space requirements, and provides continuous and unmanned control modes.
5. System automation control, single button start, simple operation, and can be paired with human-machine interface monitoring to access operation data.
