沸石浓缩转轮RC+RTO案例
沸石浓缩转轮RC+RTO

废气主要为挥发性VOC,废气总风量大但是VOC浓度较低,废气燃烧产生的热量较少,设备需额外增加较多的燃料消耗,用于对新进入的有机废气升温,直接使用RTO则运行成本会很高,因此本项目系统设备由两大主要部分所组成,即疏水性沸石转轮串连蓄热式焚化炉。它的工作原理是利用沸石分子筛所具备的的高吸附性能,对有机废气进行吸附浓缩,再由RTO设备净化处理浓缩后的有机废气。

Catalog

把有机废气加热升温至760℃,使废气中的VOC氧化分解,成为无害的CO2和H2O;氧化时的高温气体的热量被蓄热体“贮存”起来,用于预热新进入的有机废气,节省升温所需要的燃料消耗。
三室RTO由高温氧化室和三个蓄热室组成。蓄热室内的高蓄热材料能有效储存废气氧化后释放的热量,通过热交换原理预热低温废气,从而达到节约能源的目的。
为客户已出现设备腐蚀的RTO设备提供部件替换和结构升级
RTO内部储热陶瓷蓄热体在使用一定时间后需要替换,属于RTO的常规保养中的关键一项
为客户提供设备控制系统升级更新,优化控制点位
