三种包装印刷行业废气处理的方法
作者:admin 来源:http://www.sdhzyw.com 发布时间:2019-3-7 11:52:54 浏览次数:111
包装印刷行业在市场里的应用比较的广泛,发展也是越来越快,但包装印刷行业生产过程中产生的废气需要进行处理,废气处理不当就会影响到环境,现在济南宣传单页印刷要为大家介绍的就是包装印刷行业处理废气的一些方法。
Packaging and printing industry is widely used in the market, and its development is also growing faster and faster. But the waste gas produced in the production process of packaging and printing industry needs to be dealt with. The improper treatment of waste gas will affect the environment. Now Jinan publicity single-page printing is to introduce some methods to deal with waste gas in packaging and printing industry.
如果需处理有机废气的流量大、浓度低。我们可以应用废气治理技术,改善废气质量,主要方法有以下三种:
If the organic waste gas needs to be treated, the flow rate is large and the concentration is low. We can apply waste gas treatment technology to improve the quality of waste gas. There are three main methods:
(1)回收法,包括吸收法和脱附法。
(1) Recovery methods, including absorption and desorption methods.
(2)燃烧法,包括直接燃烧、蓄热式燃烧、催化燃烧、蓄热式催化燃烧。
(2) Combustion methods, including direct combustion, regenerative combustion, catalytic combustion and regenerative catalytic combustion.

(3)沸石转轮浓缩+其它技术。针对包装印刷生产产生的VOCs风量大、浓度低的特点,考虑先浓缩、后处理的思路是务实解决问题的办法。包装印刷行业所排放的VOCs浓度偏低,无论使用RTO或吸附技术来处理都有难度;用RTO技术处理,可能无法使陶瓷蓄热体维持废气自燃所需要达到的分解温度,需要添加燃料来燃烧,造成处理成本的上升;用吸附技术,处理效率过低,浪费能源。为此,采用沸石转轮浓缩+其它技术组合,可有效地对包装印刷行业所排放的VOCs进行处理。

(3) Zeolite runner concentration + other technologies. Considering the characteristics of VOCs produced by packaging and printing, such as high air volume and low concentration, the idea of concentrating first and postprocessing is a practical solution to the problem. The VOCs concentration emitted by packaging and printing industry is low, and it is difficult to treat them by RTO or adsorption technology. The decomposition temperature required for the spontaneous combustion of exhaust gas may not be maintained by RTO technology. Fuels need to be added to combustion, which results in the increase of treatment cost. Using adsorption technology, the treatment efficiency is too low and energy is wasted. Therefore, the VOCs discharged from packaging and printing industry can be effectively treated by using zeolite runner concentration plus other technology combinations.
