當今社會已發展到凡商品均需包裝,凡包裝均需印刷,污染也自然不少。包裝印刷行業的VOCs排放主要集中在印刷、烘干、復合和清洗等生產工藝過程中,主要來源于油墨、粘合劑、涂布液、潤版液、洗車水、各類溶劑等含VOCs的物料的自然揮發和烘干揮發。印刷是產品包裝zui重要的裝潢加工手段之一,印刷起著傳遞信息、宣傳介紹產品的作用。 對于印刷工藝來說,由于廢氣具有大風量、低濃度、成分復雜不具有回收價值等特點,可優先選用沸石濃縮轉輪設備(濃縮倍率5~20倍) 催化燃燒(CO) 熱能回用處理后達標排放。該法將低濃度的有機廢氣通過沸石轉輪將其濃縮成高濃度的有機廢氣,經過換熱器和燃燒區將有機廢氣加熱到280℃以上通入催化燃燒室,在催化劑的作用下使廢氣中的VOCs氧化分解成CO2和H2O,同時放出大量的熱。該高溫氣體再次經過換熱器預熱進入的廢氣,從而節省廢氣升溫燃料的消耗。 印刷行業中有機廢氣的危害及治理研究概述有機廢氣(VolatileOrganic Compounds,VOCs)一般是指室溫下飽和蒸氣壓超過70.91Pa或沸點小于260℃的有機物,在印刷行業中產生的有機廢氣,主要是由于印刷油墨的使用造成的,特別是印品干燥過程中。占油墨總量70%~80%的有機溶劑的揮發產生大量的VOCs,一方面造成人身傷害和大氣污染,另一方面也造成了有機溶劑的巨大浪費,嚴重影響企業的經濟效益。
在油墨印刷行業的印刷生產工藝中要使用大量的乙醇和少量的乙酸乙酯等溶劑用于溶解高分子樹脂,在干燥成膜的過程中有機溶劑會全部揮發,與空氣混合后排放。據估計,全國各大印刷生產廠家每年消耗乙醇等溶劑多達上萬噸,每年要向大氣中排放大量的有害物質,不僅會造成嚴重的環境污染,傷害生產工人的身體健康,而且也成為眾多企業沉重的經濟負擔,嚴重影響企業的經濟效益及競爭力。 如何消除VOCs的排放對環境的沉重壓力和對人體健康的嚴重危害是印刷行業必須要解決的問題,印刷廠廢氣處理吸附法的關鍵是吸附劑和吸附工藝設備配置,該方法是將有機氣體吸附到吸附劑上,然后再將其從吸附劑上脫離下來成為液體,收集并處理后即可重新回用于生產或出售。
上好佳包裝印刷廢氣處理
2016年5月31日,上海安居樂環保科技股份有限公司沸石轉輪+RTO設備中標全球著名品牌上好佳包裝印刷廢氣處理項目。參加本次投標的有國內外多家RTO廠家,業主終選擇了安居樂沸石轉輪+RTO設備。
沸石轉輪濃縮+GRTO裝置-有機廢氣處理設備:
安居樂VOC沸石轉輪濃縮GRTO裝置簡介: 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.
The process flow for zeolite rotary concentrator wheel+ RTO (RCO)
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.
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.
2. Advance rotary device
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.
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.
4. Advance Technology GRTO control system equipped with software and hardware interlocks, through temperature, pressure responses, the system reacts immediately to the safety control of the system. 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.
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.
