散热器型芯烘烤窑净化系统中分离器的设计研究

为解决铸铁散热器生产环境污染、产品成品率及产品质量低下等问题,笔者研制了XWJ-1型消烟雾化净化系统。该系统是根据乡镇企业实际状况,在原烘烤窑内采用烟道重新配置、油烟预处理、水雾化冷却、分离污染物、净化排放五步骤设计。通过6年多的试验运行和改进,结果证明,使用XWJ-1型油烟雾化净化系统,可以把高温、高浓度烟气中的焦油和有害气体减少90%,并分离净化到符合国家环保排放标准要求(GB9078-1996,GB16297-1996),较好地解决了热能利用、污染物回收利用等问题,提高了制芯及散热器的成品率及其质量,使企业经济效益显著提高。

Study and Designing on Smoke Purification Separate System for Kiln of Baking Cast Cores of Casting Radiators

To solve the problems of environment pollution and low percentage of qualified product in producing cast iron radiators,we designed XWJ1 smoke purification system for purification of the smoke from the kiln of the cast cores.Based on the production situation in the village enterprises,we adopted five major steps to improve the traditional kiln: reconstructing the smoke flue,pretreatment of the oil smoke,water atomizing and cooling the smoke,separating pollutes and purification of the smoke.The system has been in operation and improved for six years,test results showed that using the purification system can separate the pollutants from the smoke by 90%,and the exhausting smoke is qualified within the Standards of GB9078-1996 and GB16297-1996.Meanwhile,the separated pollutants can be reutilized.The system can also reuse some thermal energy from the flue.The direct profits of the enterprises have been improved,they are willing to use the system also because of the system being helpful for them to get their production certifications.
