Research Progress and Development Trend of Performance of Drip Irrigation Filtration Equipment for Yellow River Water
摘要
Abstract
In order to address the clogging problem of drip irrigation emitters caused by fine sediment particles(particle size<0.05 mm)in the Yellow River water,the selection of suitable filters has remained a critical consideration.Taking the Yellow River water drip irrigation filter as the research object,through literature research,the experimental research trends of the working performance of various filters under different working conditions were systematically reviewed.The main factors affecting the filtration performance and hydraulic performance of the filter were identified.The general influence patterns and mechanism of various factors on the filtration effect and hydraulic characteristics were summarized.Finally,the issues and directions requiring further investigation were put forward.The main factors affecting filter performance are the sediment characteristics of the Yellow River water and the operating parameters of the filter.Compared with other types of filters,the sand filter have the most significant effect on the water purification effect of the Yellow River,but the small particle size filter material with high concentration of raw water or small particle size sediment is more likely to induce surface filtration phenomenon.The filtration accuracy of mesh and disc filters increases with the increase of mesh number,but simultaneously,this accelerates the process of filter cake blockage and flow channel blockage,resulting in increased head loss.The combined filter shows smaller hydraulic loss and better comprehensive filtration effect.When the sediment content of the Yellow River is high,the existing filtration equipment still falls short in removing sediment particles finer than 0.05 mm Future research should further explore the filtration performance of novel filter media and combined filtration modes under varying sediment characteristics of Yellow River water,and employ CFD technology to reveal the mechanisms by which key influencing factors affect filtration performance..These findings aim to provide a solid theoretical and practical foundation for developing effective anti-clogging technology systems for drip irrigation emitters using Yellow River water.关键词
