活性炭吸附VOC的工程设计
39页1、精选优质文档-倾情为你奉上活性炭吸附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,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AbstractDue to ubiquity in the environmen
2、t and risk to human health, volatile organic compounds (VOCs) have received great attention in the field of environmental control. This design introduced an effective and the most extensive usage technology of activated carbon adsorption for cleaning volatile organic compounds (VOCs). That is to say, the project using the fixed-bed adsorption system of activated carbon to purify volatile organic compounds (VOCs). Before decontanmination, the gases would be pretreaded by the dry separator which c
3、ould wipe off the reek and dust, in order to avoid the sub-holes being jammed which would affect the efficiency of adsorption of activated carbon .Moreover the project choose activated carbon as sorbent,which has large adsorption ability and low resistance. At first, the text will introduce the condition of spray-paint waste gas,characteristics, and the present situation of cleaning of s volatile organic compounds (VOCs), and principles of them,explaining the reason to choose the technology.The
4、second, the text will describe the principle,design method and the process calculation of the design.Finally, the text will do the budget of the projet,listed the spending plan of each certain items after confirming the project, including the spending on engineering construction ,equipment ,construction supercising, equipment maintenance, and the cost of water and water and electricity, to make sure the availability of the design. At last, an all-aroud estimate and some feasible advice were sugg
