xx橡胶轮胎有限公司橡胶炼焦废气净化工程设计精品.doc

摘 要 XX橡胶轮胎厂投产10多年来，所排放的高含硫量废气，不但对周边农业和林业生产造成很大危害，而且直接影响了周边居民的身体健康。建厂以来, 该厂的污染问题一直成为群众投诉的热点。 近年来，各级环保部门和XX橡胶轮胎有限公司致力于解决废气污染扰民问题，先后建设了锅炉废气和炼胶废气处理系统，在一定程度上减轻了污染，但仍然对周边环境及附近居民存在影响。 橡胶轮胎生产过程中密炼机产生多组分废气，主要包括碳黑尘、橡胶颗粒、炼胶粉尘等尘类组份，机油、芳烃油组份及其非甲烷总烃、三苯、甲醇、甲硫醇、CS2、H2S等有机无机气体。 本设计根据《中华人民共和国国家标准--大气污染物综合排放标准》（GB16297—1996）对XX橡胶轮胎有限公司橡胶炼焦废气进行处理。 首先，对炼胶废气进行除油处理，避免由于废气中的油类物质的影响，使除尘器的除尘效果下降，甚至导致其不能正常运行工作。 然后，采用袋式除尘器，进一步去除炼胶废气中的尘类物质。除尘器使用脉冲清灰方式，选用DMC108-Ⅱ型脉冲袋式除尘器。 最后，采用新型的环式吸附器及纤维活性炭对炼胶废气进行处理，净化除味，使气体达到排放标准。活性炭吸附气体后，可用120°C的低压蒸汽脱附再生。 关键词：炼胶废气，除油器，袋式除尘器，环式吸附器 Abstract The emissions that XX 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 XX 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 XX Tire Rubber Plant caused, during the process of wasted air exhausting treatment, according to “The National Standards of Peoples 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 proper
