當(dāng)今社會(huì)已發(fā)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(yè)的VOCs排放主要集中在印刷、烘干、復(fù)合和清洗等生產(chǎn)工藝過(guò)程中,主要來(lái)源于油墨、粘合劑、涂布液、潤(rùn)版液、洗車水、各類溶劑等含VOCs的物料的自然揮發(fā)和烘干揮發(fā)。印刷是產(chǎn)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(chǎn)品的作用。 對(duì)于印刷工藝來(lái)說(shuō),由于廢氣具有大風(fēng)量、低濃度、成分復(fù)雜不具有回收價(jià)值等特點(diǎn),可優(yōu)先選用沸石濃縮轉(zhuǎn)輪設(shè)備(濃縮倍率5~20倍) 催化燃燒(CO) 熱能回用處理后達(dá)標(biāo)排放。該法將低濃度的有機(jī)廢氣通過(guò)沸石轉(zhuǎn)輪將其濃縮成高濃度的有機(jī)廢氣,經(jīng)過(guò)換熱器和燃燒區(qū)將有機(jī)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(shí)放出大量的熱。該高溫氣體再次經(jīng)過(guò)換熱器預(yù)熱進(jìn)入的廢氣,從而節(jié)省廢氣升溫燃料的消耗。 印刷行業(yè)中有機(jī)廢氣的危害及治理研究概述有機(jī)廢氣(VolatileOrganic Compounds,VOCs)一般是指室溫下飽和蒸氣壓超過(guò)70.91Pa或沸點(diǎn)小于260℃的有機(jī)物,在印刷行業(yè)中產(chǎn)生的有機(jī)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(guò)程中。占油墨總量70%~80%的有機(jī)溶劑的揮發(fā)產(chǎn)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(jī)溶劑的巨大浪費(fèi),嚴(yán)重影響企業(yè)的經(jīng)濟(jì)效益。在油墨印刷行業(yè)的印刷生產(chǎn)工藝中要使用大量的乙醇和少量的乙酸乙酯、二乙醇乙醚等溶劑用于溶解高分子樹脂,在干燥成膜的過(guò)程中有機(jī)溶劑會(huì)全部揮發(fā),與空氣混合后排放。據(jù)估計(jì),全國(guó)各大印刷生產(chǎn)廠家每年消耗乙醇等溶劑多達(dá)上萬(wàn)噸,每年要向大氣中排放大量的有害物質(zhì),不僅會(huì)造成嚴(yán)重的環(huán)境污染,傷害生產(chǎn)工人的身體健康,而且也成為眾多企業(yè)沉重的經(jīng)濟(jì)負(fù)擔(dān),嚴(yán)重影響企業(yè)的經(jīng)濟(jì)效益及競(jìng)爭(zhēng)力。 如何消除VOCs的排放對(duì)環(huán)境的沉重壓力和對(duì)人體健康的嚴(yán)重危害是印刷行業(yè)必須要解決的問(wèn)題,印刷廠廢氣處理吸附法的關(guān)鍵是吸附劑和吸附工藝設(shè)備配置,該方法是將有機(jī)氣體吸附到吸附劑上,然后再將其從吸附劑上脫離下來(lái)成為液體,收集并處理后即可重新回用于生產(chǎn)或出售。

安居樂(lè)VOC沸石轉(zhuǎn)輪濃縮GRTO裝置簡(jiǎn)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.
