沸石轉輪吸附濃縮裝置采用吸附-脫附-濃縮焚化三項連續程序，主要用于有機廢氣的治理； 特別適合于大風量，低濃度場合。該吸附裝置以陶瓷纖維為基材，做成蜂窩狀的大圓盤輪狀系統， 輪子表面涂覆疏水性沸石做吸附劑。沸石轉輪吸附濃縮裝置主要由廢氣預處理系統、分子篩轉輪濃 縮吸附系統、脫附系統、冷卻干燥系統和自動控制系統等組成。轉輪后一般有后處理系統。
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
沸石轉輪主體為一個裝滿吸附劑的旋轉輪，其被劃分為3個區域，即吸附區、再生區和冷卻區。有機 廢氣經鼓風機引入吸附區，其中的有機污染物被吸附，氣體得到凈化排出。隨后，吸附劑轉動到再 生區，在與高溫空氣接觸的過程中，VOCS被脫附下來并隨再生空氣流出，同時吸附劑獲得再生。 再生后的吸附劑先經過冷卻區降溫，然后轉動到吸附區重新進行吸附。隨著轉輪的轉動，吸附劑周 期性地進行吸附、脫附和冷卻，實現對有機廢氣的凈化。
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.
Characteristics of Zeolite Rotary Wheel Adsorption and Concentration
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, which has small 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.
