    你知道印刷廠的廢氣處理工藝嗎?

    包裝印刷車間主要生產各種塑料薄膜印刷產品。在生產加工過程中,會用到大量的彩色油墨或有機稀釋劑。油墨和產生的廢氣包括苯、甲苯、二甲苯和乙酸乙酯。如果這些VOC有機廢氣不經處理直接排放,會影響周圍環境和附近的人。
    Packaging and printing workshop mainly produces all kinds of plastic film printing products. In the production process, a large number of color inks or organic diluents will be used. Printing ink and waste gas include benzene, toluene, xylene and ethyl acetate. If these VOC organic waste gases are directly discharged without treatment, it will affect the surrounding environment and people nearby.
    印刷車間的廢氣需要先收集,再引入廢氣處理設備進行處理。印刷車間廢氣處理設備種類繁多,有催化燃燒、活性炭吸附、光氧化廢氣凈化、等離子體凈化和生物凈化等。印刷一般分為:絲網印刷、凹版印刷、凸版印刷、制版印刷等。
    The waste gas of printing workshop needs to be collected first, and then introduced into the waste gas treatment equipment for treatment. There are many kinds of waste gas treatment equipment in printing workshop, such as catalytic combustion, activated carbon adsorption, photo oxidation waste gas purification, plasma purification and biological purification. Printing is generally divided into: screen printing, gravure printing, relief printing, plate making printing, etc.

    印刷產生的空氣污染物主要是印刷過程中產生的油墨廢氣和清洗油墨用汽油揮發的氣體。溶劑型油墨(含50%-60%揮發性成分)和稀釋劑,揮發性成分的比例為70%-80%。揮發性有機物的組分通常是苯、甲苯、二甲苯、丙酮、丁酮、脂質、醚和氣溶膠。
    The air pollutants produced by printing are mainly the ink exhaust gas produced in the printing process and the gas volatilized by gasoline used to clean the ink. Solvent based ink (containing 50% - 60% volatile components) and diluent, the proportion of volatile components is 70% - 80%. The components of VOCs are benzene, toluene, xylene, acetone, butanone, lipid, ether and aerosol.
    光氧化設備在印刷車間廢氣處理中的應用
    Application of photooxidation equipment in waste gas treatment of printing workshop
    印刷車間廢氣多為有機廢氣,氣量大,濃度低。針對這種廢氣的常綠環保,建議先收集廢氣,然后將其引入UV光氧化廢氣凈化設備中。高臭氧紫外線光束分解空氣中的氧分子,產生游離氧,即活性氧。
    The waste gas of printing workshop is mostly organic waste gas with large volume and low concentration. In view of the evergreen environmental protection of this kind of waste gas, it is suggested to collect the waste gas first, and then introduce it into the UV photo oxidation waste gas purification equipment. High ozone ultraviolet beam decomposes oxygen molecules in the air and produces free oxygen, namely active oxygen.
    因為自由氧攜帶的正負電子是不平衡的,所以需要將其與它們結合產生臭氧的氧氣分離。之后,臭氧發生器產生足夠的氧離子來氧化廢氣,使廢氣產生二氧化碳和水,然后通過15米煙囪排出。
    Because the positive and negative electrons carried by free oxygen are unbalanced, it is necessary to separate them from the oxygen that produces ozone. After that, the ozonator generates enough oxygen ions to oxidize the waste gas to produce carbon dioxide and water, which are then discharged through a 15 meter chimney.
    對于上述印刷車間廢氣處理工藝,僅對其中一種進行了說明。你需要根據你的印刷設備,溶劑和墨水的成分來制定相應的解決方案。
    For the above waste gas treatment process of printing workshop, only one of them is described. You need to develop solutions based on your printing equipment, solvent and ink composition.
