涂料廢氣處理工藝簡述和產品特點

作者: 來源: 日期:2016-7-28 16:53:25 人氣:0 評論:0

  藍陽環保是一家專業生產廢氣處理設備,工業廢氣處理設備以及有機廢氣處理設備的廠家,我公司承諾能夠在最短的時間給出最好的廢氣處理解決方案。


  涂料是一種能牢固覆蓋在物體表面,起保護、裝飾、標志和其他特殊用途的化學混合物涂料。按照現代通行的化工產品的分類,涂料屬于精細化工產品?,F代的涂料正在逐步成為一類多功能性的工程材料,是化學工業中的一個重要行業。


  涂料廠所用的原料,有些具有一定的毒性,如各種溶劑、含鉛和含鉻的顏料等,可能引起中毒或職業病。有的原料如溶劑、硝化棉、油脂等屬于易燃易爆的危險品。因 此,涂料廠要有良好的通風裝置、完善的安全防爆措施和消防設備、保護工作人員健康的必要勞動保護和衛生設施。對于涂料廠廢氣的治理,要選用質量技術過硬的廢氣凈化技術,才能達到滿意的效果。


  涂料廢氣處理工藝簡述:

  1.是把有機廢氣加熱到760℃以上,停留時間大于1秒,使廢氣中的VOCs氧化分解成二氧化碳和水。

  2.氧化產生的高溫氣體流經特制的陶瓷蓄熱體,使陶瓷體升溫而“蓄熱”,此“蓄熱”用于預熱后續進入爐體的有機廢氣,從而節省廢氣升溫的燃料消耗,降低運行成本。

  3.陶瓷蓄熱體應分成三區,每個蓄熱室依次經歷蓄熱-放熱-清掃等程序,周而復始,連續工作。蓄熱室“放熱”后應立即引入適量潔凈空氣對該蓄熱室進行清掃(以保證VOC去除率在99%以上),只有待清掃完成后才能進入“蓄熱”程序。

  4.冷啟動預熱時通過燃燒器系統提高爐溫,正常運行時大部分熱量能被蓄熱陶瓷床回收,當廢氣中可燃成分濃度過低時,依靠燃燒輔助燃料(柴油或天然氣)來提升爐膛溫度。當爐膛溫度過高時,可由爐膛溫度控制的高溫排空閥門將部分熱量釋放。


  產品特點

  1.換熱穩定,占地面積小,熱回收效率高達95%;

  2.蓄熱式換熱,節省廢氣升溫的燃料消耗,降低運行成本;

  3.處理效率高達99%;

  4.采用西門子PLC-S7 1200進行電氣控制,對系統進出口、爐膛、蓄熱床等關鍵部位的控制點(如LEL監測器、溫度、壓力等)進行記錄,并通過自編程序進行邏輯控制。



     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 .
