【摘要】：我国作为全球化学原料药的生产、出口大国,全国各地遍布医药企业呈现小规模、多数量、多产品重复、低技术含量、低新药研发能力及低经济效益等趋势,医药化工企业在生产过程,产生有机溶剂废气,废气种类较多、废气量较大。同时医药企业通常采用间歇性生产,产品的种类、规格变化较大,造成了废气的排放方式和浓度也差异较大。医药废气的特征使得废气处理工艺复杂,处理成本升高,去除效率低,因此找到一套低成本高效的组合处理工艺是本论文的关键问题也是主要研究的内容之一。本文选用氮封技术、催化氧化技术作为主体工艺,对医药废气处理工艺、运行成本进行分析研究。通过对医药化工企业废气的实际处理运行结果表明,有机废气的去除率达到了98%以上,废气达标排放,达到环境保护的目的。并且该工艺具有占地面积小、运行稳定、操作方便、自动化程度高等优点,尤其适合医药化工企业。
[Abstract]:As the world's largest producer and exporter of chemical raw materials, China has shown a trend of small-scale, multi-quantity, multi-product duplication, low technological content, low R & D capability and low economic benefits of pharmaceutical enterprises throughout the country. In the production process of pharmaceutical and chemical enterprises, organic solvent waste gas is produced. At the same time, pharmaceutical enterprises usually use intermittent production, product types and specifications vary greatly, resulting in a large difference in exhaust gas emission patterns and concentrations. The characteristics of medical waste gas make the waste gas treatment process complex, the treatment cost is higher, and the removal efficiency is low. Therefore, finding a set of low-cost and efficient combination treatment process is the key problem of this paper and one of the main research contents. In this paper, nitrogen sealing technology and catalytic oxidation technology are selected as the main process to analyze and study the medical waste gas treatment process and operation cost. The results of practical treatment of waste gas in pharmaceutical and chemical enterprises show that the removal rate of organic waste gas is over 98%, the exhaust gas is up to standard and the purpose of environmental protection is achieved. The process has the advantages of small area, stable operation, convenient operation and high automation, especially suitable for pharmaceutical and chemical enterprises.
