Dimensionamento e montagem de um hidrociclone

Abstract

A hydrocyclone is a mechanical device designed to reduce or increase the concentration of a dispersed phase, solid, liquid or gas of different density, by means of centripetal forces or centrifugal forces within a vortex. The hydrocylones are equipment widely used in the mining metallurgical, petrochemical and food industries, to classify and separate mixtures of light and heavy particles. Besides the low cost, hydrocyclones have little need for maintenance, as they have no moving parts, and can be operated at low as well as high temperature and pressure, being very versatile equipment. There are some classifications of hydrocyclone types according to the relationship of their basic dimensions, the best known being the geometry Bradley and Rietema. The parameters are directly related to Dc (diameter of the cyclone cylindrical part). An important parameter is the cutting diameter (D* or D50), which corresponds to the particle size that is 50% likely to be directed to underflow or overflow. Knowing the relationships between equipment measurements is very important for your industrial design. The present work consisted in the assembly and dimensioning of a hydrocyclone, in addition to the calculation of important parameters for the study of hydrocyclones in relation to the constructed hydrocyclone. For carrying out experimental tests, water with solid sand particles (medium and fine) was used.
