近年来，随着环保政策的逐步收紧，环保设施问题已经成为了大部分工业企业面对的一个重要风险，特别是VOCs废气处理装置系统的防爆，目前常见的VOCs末端治理工艺有蓄热式燃烧（RTO）、催化燃烧（RCO）、直接燃烧（TO）、活性炭吸附脱附、低温等离子等。但VOCs废气成分复杂，通常为多种易燃易爆的混合有机气体，前期的技术工艺选择不到位或这些装置的投入使用不加以专业管理和控制，往往会带来新的隐患。比如低温等离子装置电晕放电着火问题；RTO装置爆炸问题；活性炭装置自燃以及危废处理问题。

因此，从到企业，到个人，保护环境、治理环境的首要任务是积极参与，掀起全社会环保热潮，给企业带来巨大的压力和责任感。在VOCs废气处理中，石油化工企业的废气排放浓度较高，大多采用冷凝、吸收、燃烧等方法进行废气净化处理。印刷和其他行业的废气排放浓度较低，大多采用吸附、催化和燃烧等方法进行废气净化处理，天得一推荐五种常用方法vocs废气治理方法。净化原理：利用气体与液体之间的接触，将有机废气与被污染的液体分离净化。采用气液逆吸处理，即液体自塔顶向下喷雾（或小液滴）。废气由塔（逆流）达到气液接触的目的；这种处理方法可以冷却废气，去除颗粒和净化气体，然后在除雾段处理后排入下一个处理环节。

吸附气体流程利用活性炭的物理特性对VOCs废气进行吸附，且蜂窝状活性炭比表面积大、吸附能力不错的特性，将废气吸附到活性炭的微孔中，从而使气体得以净化，净化后的气体再通过风机排空；

目前、治污设施简易低效，VOCs废气组分复杂，治理技术多样，适用性差异大，技术选择和系统匹配性要求高，我国vocs废气治理市场起步较晚，准入门槛低，治污设施建设质量良莠不齐，应付治理在一些地区，低温等离子，光催化，光氧化等低效技术应用甚至达80%以上？治污效果差一些企业由于设计不规范。系统不匹配等原因，即使选择了治理技术也未取得预期治污效果。

宁波vocs有机废气治理常见型号(原来这家好，2022已更新)kHMdmo——"有很多种多样方式给您选用，前提条件是无论选用哪样净化方式或是方法。一定要考虑空气污染物环保标准或是地区的环保标准。废气处理设备的过程:经过液体吸收装置。除雾层，填料层，油雾过滤器和活性炭吸附塔处理后，油雾等颗粒物和SO2，NOX、ch等气体污染物可被有效去除，技术先进可靠，该技术的核心是活性炭吸附装置，废气通过收集系统进入洗涤塔进行洗涤。去除喷漆废气中的灰尘和部分有机废气。然后进入油漆过滤器去除漆雾，再经活性炭吸附塔吸附净化，净化后的气体通过风机排入大气。"
