Modeling the classification ability of filtering hydrocyclone

Abstract

Abstract The construction of a hydrocyclone with the filtering side surface drain pipe has been developed, which allows increasing the water purification rates from mechanical impurities, including by capturing the smallest suspensions. As a result of experimental research of the effect of the flow characteristics and size of the sand pipe on the classification ability of the apparatus, the technological and construction parameters of the PH-100 hydrocyclone with various versions of the drain pipe, providing maximum efficiency of water purification from mechanical impurities, have been established. Graphoanalytic solution of the obtained regression equations has allowed us to establish that a hydrocyclone with a solid side surface drain pipe provides the maximum degree of water purification from mechanical impurities at the level of 85.4% at a flow rate of 6.5 m3 / h and a diameter of 12 mm sand pipe. Replacing the standard construction drain pipe with a filtering side surface drain pipe increases the integral degree of water purification from mechanical impurities to 96.4% with the same flow parameters and the diameter of the sand pipe.
