毕业论文-陶瓷基片烧结炉废气治理工程设计.doc

I I 设计总说明本毕业设计的对象是广东潮州三环(集团)股份有限公司的陶瓷基片生产过程中产生的恶臭气体。在陶瓷基片成型加工过程中,主体原料氧化铝系粉体,需要用聚乙烯醇缩丁酸( PVB ) 、二丁酯( DBP )等黏合剂粘合。因此陶瓷胚基片中含有聚乙烯醇缩丁酸( PVB ) 、二丁酯( DBP )等有机物, 经高温烧结工艺后从基片中挥发出恶臭气体, 影响到周围民众的正常生活。此恶臭气体为有机废气,考虑到有机废气的净化率和工程实际情况与经济可行性,本毕业设计通过对恶臭去除各种方法的比较并结合潮州市三环(集团)股份有限公司生产陶瓷基片工艺的实际情况,决定采用直接燃烧法处理工艺对产生的恶臭进行处理,使其气体排放达到环境的要求标准。广东潮州三环(集团)股份有限公司生产陶瓷基片的过程中,产生的恶臭是由于聚乙烯醇缩丁酸( PVB ) 、二丁酯( DBP )等有机物所引起的。在高温下, 聚乙烯醇缩丁酸( PVB ) 、二丁酯( DBP )等有机物被氧化,氧化反应剧烈且完全彻底, 其氧化产物是对人体无害的二氧化碳和水。根据此原理,对生产过程中产生的有机废气(恶臭)用专用的管道进行集中收集,将收集到的气体送入烧结炉烧结段进行燃烧,燃烧后的热烟气又经锅炉引风机加压,进入烧结炉预热段的间接换热器,如此周而复始。经间接换热器换热后的低温烟气汇集后经烟囱排放,从而使恶臭污染问题得以解决。关键词: 陶瓷基片, 直接燃烧法,恶臭 II II Abstract The graduation project is the subject of Chaozhou in Guangdong tricyclic (Group) Company Limited production of ceramic substrates in the course of the stench of gas. Ceramic substrates in the process of forming, the main raw material of aluminum powder, the need for polyvinyl butyrate (PVB), dibutyl (DBP), such as adhesive bonding. Therefore ceramic embryo-containing polyvinyl acid tablets (PVB), dibutyl (DBP) and anic matter, the high temperature sintering technology-based tablets from the volatile after the stench of gas, affecting the normal life of people around. The stench anic gases emissions, taking into account anic waste gas purification rate and engineering and economic feasibility of the actual situation, the stench graduated from design through various methods of removal of Chaozhou City and three-ring (Group) Company Limited production of ceramics Substrate of the actual situation, decided to adopt the bustion process on the stench processed gas emissions to meet the requirements of environmental standards. Chaozhou in Guangdong tricyclic (Group) Company Limited production of ceramic substrates in the process, the stench is polyvinyl butyrate (PVB), dibutyl (DBP) and anic matter caused by. Under high temperature, polyvinyl butyrate (PVB), dibutyl (DBP) and anic matter by oxidation, and the intense reaction of full plete, its oxidation produc
