the hydrocyclones also called cones are the most important parts of desander and desilters. today dc solid control shippped 100sets desilter hydrocyclones to singapore clients by air. desilter cones are typically 4” but some client will request 3” 5” as well. so it is rather flexible on capacity configuration.
the inline desilter is designed for use in areas that cannot accommodate the spatial requirements for the round desilter configuration. both the round and inline desilters are available in a variety of sizes up to 20 cone models. available cone quantity dependent on machine type.
hydrocyclones also called desanders or desilters operate by directing the water into a cone through a tangential inlet that imparts rotational movement to the water. figures 4.8a and 4.8b show a hydrocyclone cone and an assembly of eight cones.
hydrocyclones are arranged with the unit of larger cone size upstream of the smaller unit. a separate tank is needed for each size unit. generally a desander and a desilter manifold are available as part of the rig equipment. hydrocyclones should process all drilling fluid entering their suction compartments independently of the drilling-fluid circulation rate. …
desilters utilize smaller hydrocyclones and are used to process mud that has already been cycled through the desander. the number of cones in a desilter is greater than the corresponding desander as the smaller cones accommodate lower flow rates. desilters are comprised of either 4″ or 5″ cones whereas each 4″ cone is capable of removing
