涂料废气处理工艺简述和产品特点

作者: 来源: 日期:2016-7-28 16:53:25 人气:0 评论:0

  蓝阳环保是一家专业生产废气处理设备,工业废气处理设备以及有机废气处理设备的厂家,我公司承诺能够在最短的时间给出最好的废气处理解决方案。


  涂料是一种能牢固覆盖在物体表面,起保护、装饰、标志和其他特殊用途的化学混合物涂料。按照现代通行的化工产品的分类,涂料属于精细化工产品。现代的涂料正在逐步成为一类多功能性的工程材料,是化学工业中的一个重要行业。


  涂料厂所用的原料,有些具有一定的毒性,如各种溶剂、含铅和含铬的颜料等,可能引起中毒或职业病。有的原料如溶剂、硝化棉、油脂等属于易燃易爆的危险品。因 此,涂料厂要有良好的通风装置、完善的安全防爆措施和消防设备、保护工作人员健康的必要劳动保护和卫生设施。对于涂料厂废气的治理,要选用质量技术过硬的废气净化技术,才能达到满意的效果。


  涂料废气处理工艺简述:

  1.是把有机废气加热到760℃以上,停留时间大于1秒,使废气中的VOCs氧化分解成二氧化碳和水。

  2.氧化产生的高温气体流经特制的陶瓷蓄热体,使陶瓷体升温而“蓄热”,此“蓄热”用于预热后续进入炉体的有机废气,从而节省废气升温的燃料消耗,降低运行成本。

  3.陶瓷蓄热体应分成三区,每个蓄热室依次经历蓄热-放热-清扫等程序,周而复始,连续工作。蓄热室“放热”后应立即引入适量洁净空气对该蓄热室进行清扫(以保证VOC去除率在99%以上),只有待清扫完成后才能进入“蓄热”程序。

  4.冷启动预热时通过燃烧器系统提高炉温,正常运行时大部分热量能被蓄热陶瓷床回收,当废气中可燃成分浓度过低时,依靠燃烧辅助燃料(柴油或天然气)来提升炉膛温度。当炉膛温度过高时,可由炉膛温度控制的高温排空阀门将部分热量释放。


  产品特点

  1.换热稳定,占地面积小,热回收效率高达95%;

  2.蓄热式换热,节省废气升温的燃料消耗,降低运行成本;

  3.处理效率高达99%;

  4。采用西门子PLC-S7 1200进行电气控制,对系统进出口、炉膛、蓄热床等关键部位的控制点(如LEL监测器、温度、压力等)进行记录,并通过自编程序进行逻辑控制。



     LANYANG  is a professional production of waste gas treatment equipment, waste gas treatment equipment and industrial organic waste gas treatment equipment manufacturers, our company is committed to give the best possible exhaust gas processing solutions in the shortest time。


Paint is a firm can cover the surface, the protective, decorative, chemical mixture paint logos and other special purposes。 In accordance with the prevailing modern classification of chemical products, coating belonging to fine chemical products。 Modern paint is gradually becoming a class versatility of engineering materials, the chemical industry is an important industry。


Raw materials used in paint factory, some of which have some toxicity, such as various solvents, lead and chromium pigments, etc., may cause poisoning or occupational disease. Some materials such as solvents, nitrocellulose, grease, etc. is flammable and explosive dangerous goods. Therefore, the paint factory have good ventilation, sound-proof safety measures and fire-fighting equipment to protect the health of workers necessary labor protection and sanitation. For coating plant waste gas treatment, to use quality technical excellent exhaust gas purification technology, in order to achieve satisfactory results.


Paint waste gas treatment Process Description:


1。 The organic waste is heated to above 760 ℃, residence time greater than one second, so that the exhaust gas VOCs oxidation and decomposition into carbon dioxide and water。


2。 The high-temperature gas flowing through the oxidation of a special ceramic regenerator, heating the ceramic body and the "regenerative", this "regenerative" is used to preheat the follow-up into the body of organic waste, thus saving fuel consumption exhaust gas temperature rise and lower operating costs。


3. ceramic regenerator should be divided into three zones, each goes through the regenerator heat storage - heat - such as cleaning procedures, again and again, continuously. After regenerator "heat" should be immediately introduced into the appropriate amount of clean air to the regenerator for cleaning (to ensure that the VOC removal efficiency above 99%), and only until the cleaning is completed to enter the "regenerative" program.


4. improve cold start preheating furnace through the burner system, the normal operation of most of the heat can be recovered regenerative ceramic bed, when the combustible components in the exhaust gas concentration is too low, rely on combustion auxiliary fuel (diesel or natural gas) to improve furnace temperature. When the furnace temperature is too high, the valve may be emptying temperature furnace temperature control part of the heat will be released.



Product Features


1. Heat stable, small footprint, heat recovery efficiency up to 95%;


2。 The regenerative heat exchanger, exhaust gas temperature rise of saving fuel consumption, lower operating costs;


3. efficiency up to 99%;


4. Siemens PLC-S7 1200 is electrically controlled, import and export of key parts of the system, furnace, heat storage bed control points (eg LEL monitors, temperature, pressure, etc.) are recorded, and logic control through self programming .
