Firstly, changing structural and operating properties of a basic hydrocyclone, the experimentation was finished in an simulative test apparatus excluding sediments from the Yellow river. Then,the effects discipline on concentration of overflow , separation] efficiency, separation Particle size were qualitatively summarized and evaluated through the analyzes of the concentration of overflow , gradation efficiency, median diameter,which aims to improve the performance of Hydrocyclone using in excluding sediments from the yellow river,so lots of theory preparations were given to research on second part of the research ,the author did much work on fluid field.Many investigation was done on the character of vortex , the distribution of velocity and short circ how to develop a set of equipment on Huang He river solid-liquid separation.In the uit flow ,the formation of air flow .The author also shows some points of her own . |
