摘要
随着人类社会的快速发展,环境保护也成为人们关注的焦点。大气污染是造成环境污染的主要污染源之一。大气污染中,主要污染物有硫化物、氮氧化物、粒子状污染物等。去除废气中的硫化物(即脱硫)已成为废气净化领域的研究热点。本文通过研究气体脱硫领域的国内专利文献,对该领域的专利申请趋势、申请人的多角度分析、专利的转让人和受让人分析等,为该领域的专利申请、专利布局和运用提供参考。
With the rapid development of human society,environmental protection has become the focus of attention.Air pollution is one of the main sources of environmental pollution.In atmospheric pollution,the main pollutants are sulfides,nitrogen oxides,particulate pollutants,etc.Removal of sulfide in waste gas(desulfurization)has become a research hotspot in the field of waste gas purification.By studying the domestic patent literature in the field of gas desulfurization,this paper analyzes the trend of patent application in this field,the multi-angle analysis of applicants,the assignor and assignee of patents,etc.,and provides reference for patent application,patent layout and application in this field.
