容器表面油质污染物水射流驱除特性研究
Research on the Water Jet Removal Characteristics of Oily Pollutants on the Surface of Containers
摘要
Abstract
In the process of recycling oil-containing containers,there is a problem of oily pollutants adhering to the surface,which is difficult to deeply clean.The high-pressure water jet flushing method is adopted to form an impact shear force at the edge of the oily pollutants in the container,and it is applied to the oily pollutants to achieve the effect of removing the oily pollutants.Based on the interfacial tension between the oily pollutants and the container surface,a spherical crown oil phase slip separation model is proposed,the critical jet velocity of the water jet is calculated,and a Fluent analysis model of oil phase slip under the action of the water jet is established.The effect of different incidence angles on the removing effect of oily pollutants under certain target distances and inlet pressures is explored.The research shows that at the edge of the container oily pollutants,the position and volume fraction of the oily pollutants change significantly,indicating that it is affected by the strong thrust and shear force of the water jet.The cleaning efficiency of the oily pollutants increases first and then decreases with the increase of the water jet incidence angle,and the efficiency is the highest when the incidence angle is 50°.The high-speed characteristic of the water jet provides enough energy for the oily pollutants to overcome the interfacial tension it receives,thus achieving the purpose of removal.The research results of this paper are instructive for the surface cleaning and deoiling of oil-containing containers and can also be applied to related cleaning fields.关键词
