印刷廠廢氣處理催化燃燒設(shè)備是近幾年廣泛應(yīng)用于印刷車間廢氣處理，同時(shí)也是多數(shù)環(huán)評(píng)上指定使用該設(shè)備對(duì)印刷廠產(chǎn)生的廢氣進(jìn)行處理后達(dá)標(biāo)排放。小編簡(jiǎn)單介紹下催化燃燒設(shè)備在印刷廠中的應(yīng)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.

印刷廠的廢氣主來源于印刷過程中采用的油墨、甲苯、汽油、酒精等有機(jī)溶劑揮發(fā)。尤其是在印刷品干燥的過程中，油墨所散發(fā)的揮發(fā)性組分的總含量占70%-80%，不進(jìn)處理排放氣體不僅污染周圍環(huán)境，還會(huì)對(duì)人體的健康造成危害。

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.

印刷廠廢氣處理催化燃燒設(shè)備利用廢氣進(jìn)行燃燒產(chǎn)生出的能量入吸附床脫附時(shí)，此時(shí)加熱裝置停止工作，有機(jī)廢氣在催化燃燒室內(nèi)維持自燃，循環(huán)進(jìn)行，直至有機(jī)物從活性炭?jī)?nèi)部分離，至催化室分解。余熱經(jīng)過蓄熱床進(jìn)行回收，便于下次加熱及余熱，能量回收效率高，能耗小，有機(jī)物得到催化分解處理。

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.

催化燃燒設(shè)備能去除揮發(fā)性有機(jī)物(VOC)、無機(jī)物、硫化氫、氨氣、硫醇類等主要污染物，以及各種惡臭味，脫臭效率可達(dá)98%以上，脫臭效果大大頒布的惡臭污染物排放標(biāo)準(zhǔn)無需添加物質(zhì)：只需要設(shè)置相應(yīng)的排風(fēng)管道和排風(fēng)動(dòng)力，使惡臭氣體通過本設(shè)備進(jìn)行脫臭分解凈化，無需添加物質(zhì)參與化學(xué)反應(yīng)。

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.

其具體還需根據(jù)業(yè)主現(xiàn)場(chǎng)廢氣總風(fēng)量大小、凈化要求、設(shè)備運(yùn)轉(zhuǎn)與建造經(jīng)濟(jì)性、現(xiàn)場(chǎng)工況、廢氣濃度等具體工況綜合考慮。采用不同工藝。比如中低濃度、中高風(fēng)量有機(jī)廢氣采用活性炭吸附-脫附-催化燃燒進(jìn)行凈化，高濃度采用蓄熱式焚燒爐。

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.
