印刷厂废气处理催化燃烧设备是近几年广泛应用于印刷车间废气处理，同时也是多数环评上指定使用该设备对印刷厂产生的废气进行处理后达标排放。小编简单介绍下催化燃烧设备在印刷厂中的应用。

The catalytic combustion equipment for printing factory exhaust gas treatment has been widely used in printing workshop exhaust gas treatment in recent years, and it is also designated in most environmental impact assessments to use this equipment to treat the exhaust gas generated by printing factories and achieve standard emissions. The editor briefly introduces the application of catalytic combustion equipment in printing factories.

印刷厂的废气主来源于印刷过程中采用的油墨、甲苯、汽油、酒精等有机溶剂挥发。尤其是在印刷品干燥的过程中，油墨所散发的挥发性组分的总含量占70%-80%，不进处理排放气体不仅污染周围环境，还会对人体的健康造成危害。

The main source of exhaust gas from printing factories comes from the volatilization of organic solvents such as ink, toluene, gasoline, and alcohol used in the printing process. Especially during the drying process of printed materials, the total content of volatile components emitted by ink accounts for 70% -80%. Untreated emissions not only pollute the surrounding environment, but also pose a threat to human health.

印刷厂废气处理催化燃烧设备利用废气进行燃烧产生出的能量入吸附床脱附时，此时加热装置停止工作，有机废气在催化燃烧室内维持自燃，循环进行，直至有机物从活性炭内部分离，至催化室分解。余热经过蓄热床进行回收，便于下次加热及余热，能量回收效率高，能耗小，有机物得到催化分解处理。

When the catalytic combustion equipment for waste gas treatment in the printing factory uses the energy generated by combustion of waste gas to desorb in the adsorption bed, the heating device stops working, and the organic waste gas maintains spontaneous combustion in the catalytic combustion chamber, circulating until the organic matter is separated from the activated carbon and decomposed in the catalytic chamber. The waste heat is recovered through a heat storage bed, which facilitates the next heating and waste heat recovery. The energy recovery efficiency is high, the energy consumption is low, and the organic matter is catalyzed and decomposed.

催化燃烧设备能去除挥发性有机物(VOC)、无机物、硫化氢、氨气、硫醇类等主要污染物，以及各种恶臭味，脱臭效率可达98%以上，脱臭效果大大颁布的恶臭污染物排放标准无需添加物质：只需要设置相应的排风管道和排风动力，使恶臭气体通过本设备进行脱臭分解净化，无需添加物质参与化学反应。

Catalytic combustion equipment can remove major pollutants such as volatile organic compounds (VOCs), inorganic substances, hydrogen sulfide, ammonia, thiols, and various odors, with a deodorization efficiency of over 98%. The emission standards for odor pollutants with greatly deodorized effects do not require the addition of substances: only corresponding exhaust pipes and exhaust power need to be set up to allow odor gases to undergo deodorization, decomposition, and purification through this equipment, without the need to add substances to participate in chemical reactions.

其具体还需根据业主现场废气总风量大小、净化要求、设备运转与建造经济性、现场工况、废气浓度等具体工况综合考虑。采用不同工艺。比如中低浓度、中高风量有机废气采用活性炭吸附-脱附-催化燃烧进行净化，高浓度采用蓄热式焚烧炉。

It also needs to be comprehensively considered based on the total amount of exhaust gas flow at the owner's site, purification requirements, economic efficiency of equipment operation and construction, on-site conditions, exhaust gas concentration, and other specific working conditions. Using different processes. For example, organic waste gases with medium to low concentrations and medium to high wind volumes are purified using activated carbon adsorption desorption catalytic combustion, while high concentrations are purified using a thermal storage incinerator.
