摘要
華南橡膠輪胎廠投產(chǎn)10多年來，所排放的高含硫量廢氣，不但對(duì)周邊農(nóng)業(yè)和林業(yè)生產(chǎn)造成很大危害，而且直接影響了周邊居民的身體健康。建廠以來, 該廠的污染問題一直成為群眾投訴的熱點(diǎn)。
近年來，各級(jí)環(huán)保部門和華南橡膠輪胎有限公司致力于解決廢氣污染擾民問題，先后建設(shè)了鍋爐廢氣和煉膠廢氣處理系統(tǒng)，在一定程度上減輕了污染，但仍然對(duì)周邊環(huán)境及附近居民存在影響。
橡膠輪胎生產(chǎn)過程中密煉機(jī)產(chǎn)生多組分廢氣，主要包括碳黑塵、橡膠顆粒、煉膠粉塵等塵類組份，機(jī)油、芳烴油組份及其非甲烷總烴、三苯、甲醇、甲硫醇、CS2、H2S等有機(jī)無機(jī)氣體。
本設(shè)計(jì)根據(jù)《中華人民共和國(guó)國(guó)家標(biāo)準(zhǔn)--大氣污染物綜合排放標(biāo)準(zhǔn)》（GB16297—1996）對(duì)華南橡膠輪胎有限公司橡膠煉膠廢氣進(jìn)行處理。
首先，對(duì)煉膠廢氣進(jìn)行除油處理，避免由于廢氣中的油類物質(zhì)的影響，使除塵器的除塵效果下降，甚至導(dǎo)致其不能正常運(yùn)行工作。
然后，采用袋式除塵器，進(jìn)一步去除煉膠廢氣中的塵類物質(zhì)。除塵器使用脈沖清灰方式，選用DMC84-Ⅱ型脈沖袋式除塵器。
最后，采用新型的環(huán)式吸附器及纖維活性炭對(duì)煉膠廢氣進(jìn)行處理，凈化除味，使氣體達(dá)到排放標(biāo)準(zhǔn)。活性炭吸附氣體后，可用120°C的低壓蒸汽脫附再生。

Abstract
The emissions that South China Tire & Rubber plant exhausted, which included high level of sulfur, not only cause a great risk to the agricultural and forestry industries nearby, but also affects the surrounding residents of their health directly since 10 years ago. The pollution problem has become the hot spot that people complains since then.
In recent years, the environmental protection departments at all levels and the South China Tire & Rubber Limited Company, Guangzhou committed to solving air pollution nuisance. The company has built a boiler and rubber exhaust emissions processing system, which has reduced pollution in a certain extent. But the exhaust emissions are still impacting the surrounding environment and the nearby residents there.
In rubber tire production process ,mixer produces multi-component emissions, including carbon black dust, rubber granules, rubber dust and other dust components; oil, aromatic oil components and non-methane hydrocarbons, toluene, methanol, methyl mercaptan, CS2, H2S and other organic and inorganic gases.
This design is set up to deal with the problem that South China Tire & Rubber Plant caused, during the process of wasted air exhausting treatment, according to “The National Standards of People's Republic of China -- atmospheric pollutant discharge standards” (GB16297- 1996)
First, eliminate the oil from the emissions, avoiding that the effect of the dust collector declines, even it can not operate properly with the oil.
Then, use bag filter on the process, and further removed the dust-like substances from the emissions. Bag filter uses pulse filter cleaning methods. DMC84- II pulse jet bag filter is selected.
Finally, the novel ring adsorption bed and activated carbon fiber are disposing the emission, cleaning the taste, reaching the gas emission standards. After absorbing the gases, Activated Carbon are renewed in the 120 ° C in low-pressure steam.
Keywords : Compound emissions, Oil remover, Bag filter, Ring adsorption bed
