1、专业技术资料分享活性炭吸附VOC的工程设计摘要近年来，人们逐渐认识到有机废气对环境和人类健康的巨大危害性，因此在环境工程领域对有机废气的治理越来越受到人们的重视。本设计将介绍一种有效且最广泛使用的工业有机废气的净化技术—活性炭吸附法。本设计利用活性炭固定床吸附系统对工业有机废气进行净化。经过该系统之前，废气会先用干式除尘器进行预处理，去除废气中的雾状物及粉尘，从而避免了这些物质堵塞活性炭微孔，影响活性炭的吸附效性能。而在活性炭吸附器的设计上，本文采用了卧式多层设计。选用活性炭为吸附剂，具有吸附性能好，流体阻力小的特点。首先本文将概述当前有机工业废气的处理现状，主要处理方法和优缺点，
2、并且阐述本设计所采用该技术的原因。其次，本文将系统介绍所采用技术的基本原理，设计原则和设计过程计算。最后，对本毕业设计的造价和费用进行工程预算，包括工程施工费用、设备费用、工程管理费用、设备维护费用和水电费等等，确定其经济可行性。还给出了综合性的评价和可行性的建议。关键词：工业有机废气，干式除尘器，固定床吸附器，活性炭WORD文档下载可编辑专业技术资料分享AbstractDuetoubiquityintheenvironmentandrisktohumanhealth,volatileorganiccompounds(VOCs)havereceivedgreatattentioni
