在包装印刷行业生产过程中，会有大量乙醇、乙酸乙酯、乙酸丁酯、乙酸丙酯以及甲苯、二甲苯等有机气体挥发排放.印刷生产车间废气成分主要是油墨溶剂产生的废气甲苯、苯、乙酸乙酯、乙酸丁酯、200号溶剂油、乙醇、丁醇等.使用的油墨主要含有色料、树脂、溶剂、辅助 剂等，废气产生的主要在上墨及烘干、复合过程，挥发出来有机溶剂是废气污染的主要来源。印刷废气成分复杂，异味重，易燃易爆，废气未经净化排出后对周边环境较大. 同时，由于VOC的成分复杂，各种污染物的特性不同，因此任何单一的VOC控制方法均受其去除性能、投资运行费用和适用范围的影响。目前在我国的包装塑料基材等印刷过程中大量使用的溶剂型油墨，含有50%-60%的挥发性组分，如果加上调油墨粘度所需的稀释剂，那么在印品干燥时，挥发性组分的总含量为70%-80%。这些有机溶剂所挥发的气体，通过呼吸进入人体内，对人体的肝脏和神经系统造成损害；有机化合物排放到大气中，与氮氧化物反应，发生光化学反应，形成光化学氧化剂而毁坏森林与破坏生态环境。
包装印刷是以美化、识别、宣传商品为主要目的而采用的印刷方式和印后加工处理技术，是应用一般印刷技术成果，在一般印刷技术的基础上发展起来并形成一个新的印刷工业体系。因此，包装印刷不仅是现代包装的重要组成部分，而且也是印刷技术领域的一个新的分支，成为中国一个举足轻重的行业。
包装印刷厂的主要产品为各种塑料薄膜的印刷制品，在生产中大量使用彩色油墨和有机稀料，油墨用的稀料(溶剂)主要是甲苯、乙酸乙酯、及少量丁 酮。这些溶剂在产品生产过程中变为VOCs废气大量排出。这些有机废气处理为有害气体，因此，对包装印刷厂生产车间排出的VOCs废气必须采取有效的收集方法和净化工艺进行处
污染物处理不达标，企业限期整改？
污染物超标排放，面临巨额罚款？
因环保问题而强制停业整顿？
污染问题太复杂，解决一个问题又出现其他问题？
盲目上设备，却使用并不适合自己公司成套废气污水处理系统劳民伤财？
安居乐VOC沸石转轮浓缩GRTO装置简介:
Zeolite Rotary Concentrator Wheel+ GRTO:

How to treat low concentration with large air flow waste stream? Shanghai Anjule has patent designed solutions with the zeolite concentrators to reduce the air flow of the pollutant and concentrate the VOCs before the RTO treatment. Improve the removal efficiency, reduce the operating cost while meeting the regulations. This is a leading technologies in treating VOCs and HAP.
常规有机废气浓缩转轮和RTO（RCO）处理流程如下：
The process flow for zeolite rotary concentrator wheel+ RTO (RCO)
安居乐的工艺技术更加贴近废气工况，以大风量的喷漆废气处理为例：
车间排放有机废气通过总管道送至G涡流净化塔做漆雾颗粒去除处理，后经过除雾器，再经过专门设计的组合过滤器后，由VOC沸石浓缩转轮吸附区吸附，吸附效率为90%以上；排放废气由吸附风机抽出，并达标排放；
浓缩转轮吸附住的有机物，从转轮脱附区域脱附出来进入RTO高温氧化处理
Anjule technology can be applied to work with the process specifications. For example, emission from coating industrial has the characteristic of high air volume: the waste gas was sent to the G-vortex column to remove particulate. After the dehumidifier process, the waste gas was sent to a specially designed filter before entering the rotary concentrator for VOCs adsorption. The removal efficiency can achieve VOC removal efficiency above 90%. A system fan was installed to release the cleaned air, which is in compliance with the regulations. The air stream then transfer to the RTO for further treatment.
一、转轮入口G涡流净化塔
安居乐G涡流洗涤净化塔采用独特的涡流结构；净化去除有机废气中漆物，以满足转轮入口条件；优点：1、不易堵塞，无需更换填料。2、运行成本低。3、漆粒去除效率高，防治漆粒积蓄在转轮上发生火灾。
1. Rotary entrance with G-vortex column
Anjule G-vortex column has a unique vortex structure, purify and remove the paint organic substance from gas.
The advantage: 1. Avoid the blockage of the packing media; reduce the operating cost; and achieve high removal efficiency of VOC substance. Minimize the accumulation of the paint substance on the rotary and at a result prevent fire hazard.
二、先进转轮装置
2. Advance rotary device
安居乐设有专门的VOC处理实验室，废气治理实验工程中心，转轮装置引进日本，实验测试具体成分的转轮效率，保障项目的成功率。转轮吸附装置的优点体积小、操作方便、压降低；它可以连续地将大的废气流量处理成浓度足够低的净化气，而解吸出来的气体则浓度高而流量低，从而进入低风量RTO装置彻底燃烧。
Aujule has set up a laboratory and an engineering center for the design of the exhaust gas VOC treatment. The rotary wheels are imported from Japan; the VOC compounds removal rate are measured in a laboratory to ensure the successful treatment for the environmental projects.
The advantage of our rotary concentrator: small size, convenience, low pressure lost and work continuously to concentrate low VOC concentration waste gas. The rotary processed gas has a high concentration of VOC with less volume and therefore reduce the amount of the waste gas for the RTO treatment.
三、安全性高
安居乐独家专利设计的GRTO工艺充分考虑了消防、防爆等安全因素，运行稳定，安全可靠，工艺完整。
3. Safety guarantee
Patent designed of Anjule GRTO has put the fire, explosions and other safety factors into fully consideration. The operation of the GRTO is steady, safe and reliable.
四、技术先进性

Effectively，protect the safety of the system . RTO control system uses PLC, installed inside of the control panels; equipped with flame intensity detector, temperature controllers, alarm, reset, on and off switch, emergency stop, and a recorder; RTO system works seamlessly with the production line without interfering to the existing production.
五、运行费用优势
浓度越高运行成本越低。所以采取合理的技术手段增加有机废气进入RTO（RCO）时的浓度，以及减少废气处理量是减少RTO（RCO）投资与提高运行效率的有效途径。
5. The low operating cost advantage
Lower operating cost can be achieved with high VOC concentration in the waste stream. Using a rotary concentrator to reduce the volume of the waste gas is a feasible way in decreasing the cost.
