采用吸附、解析性能优异的活性炭(颗粒炭、活性炭纤维和蜂窝状活性炭)作为吸附剂,吸附企业生产过程中产生的有机废气,并将有机溶剂回收再利用,实现了清洁生产和有机废气的资源化回收利用。
活性炭吸附回收技术是循环经济的一种良好应用,在不使用深冷、高压等手段下,达到节能降耗的目的,同时使净化效率达到90%以上,显著减少了二氧化碳等温室气体的排放,市场潜力巨大。
可广泛应用于包装印刷、石油、化工、化学药品原药制造、涂布、纺织、集装箱喷涂及合成材料等行业有机废气的治理。
环保部发布的《挥发性有机物(VOCs)污染防治技术政策》中明确提出:
在工业生产过程中鼓励VOCs的回收利用,并优先鼓励在生产系统内回用;
对于含高浓度VOCs的废气,宜优先采用吸附回收、冷凝回收技术进行回收利用,并辅助以其他治理技术实现达标排放;
对于含中等浓度VOCs的废气,可采用吸附技术回收有机溶剂,或采用催化燃烧和热力焚烧技术净化后达标排放;
对于含低浓度VOCs的废气,有回收价值时可采用吸附技术、吸收技术对有机溶剂回收后达标排放;
不宜回收时,可采用吸附浓缩燃烧技术、生物技术、吸收技术、等离子体技术或紫外光高级氧化技术等净化后达标排放。
【适用范围】
包装印刷、石油、化工、化学药品原药制造、涂布、纺织、集装箱喷涂及合成材料等行业。
