​​喷漆房废气vocs处理方案，根据喷涂的工艺和原料，排放的废气和粉尘属于大风量、低浓度的漆雾粉尘颗粒和有机混合气体，根据长期经验、相关行业要求、资料参数及减少用户投资成本、运行维护费用，本项目选用活性炭吸附浓缩+催化燃烧法净化处理，预处理采用干式过滤除尘。

采用一次性颗粒状活性炭处理VOCs废气，年活性炭使用量不应低于VOCs产生量的5倍，即1吨VOCs产生量，需5吨活性炭用于吸附，活性炭更换周期一般不应超过累计运行500小时或3个月，更换周期计算按有关要求执行。

喷烤漆废气处理工艺说明：风机→漆雾过滤器/水帘除雾/旋流喷淋塔→过滤棉吸附→活性炭吸附装置/光氧化废气净化设备→离心风机→15米高排

该材料也是催化剂的好选择，甚至比半导体材料更节能、更环保，属于未来的光分解处理VOC选择废气催化剂是技术领域的一大进步。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。

气处理可以采用燃烧法、吸附浓缩热氧化、吸附回收净化、微生物净化、热破坏、变压吸附分离与净化的方法来处理。

废气均匀地通过吸附箱内的活性炭层的过流断面，在一定的停留时间，由于活性炭表面与有机废气分子间相互引产生物理吸附作用，将废气中的有机成份吸附在活性炭的表面积，从而使废气得到净化，净化后的洁净气体通过风机及烟囱达标排放。

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。
