A Review on Recent Patents for Oil Mist Separation Devices

Abstract

Oil mist separation technology and oil mist separation devices are indispensable components of modern industry and engines and are important means to improve air quality and reduce oil mist diffusion. However, in the study of their separation efficiency and oil droplet collection, there are still some techniques that need breakthroughs to be able to better separate oil mist in the future. Through the introduction and discussion of the patent characteristics of oil mist separation devices in recent years, some valuable conclusions are summarized, and future research and development have been prospected. The patents of various separation devices were studied, and the patents and research prospects of oil mist separation devices were summarized. With the development of the machinery industry, oil mist separation has become more and more important, so a separation device is required to realize the separation, collection, recycling, and utilization of oil mist. By elaborating on the structural characteristics of the separation device, the importance of the separation device is discussed. By comparing these patents, it is concluded that electrostatic separators and composite separation devices are the main development trends of future separation devices.
