Systematische Untersuchung von Hydrovakuumzyklonen
Systematic study of hydro vacuum cyclones
Hydrocyclones form an indispensable part of mobile separation plants as they boast high separating efficiency combined with expediently simple design. Hydro vacuum cyclones are a special type of these separating units. Their characteristic feature is an automatically operating closing mechanism in the underflow of the cyclone. This closing mechanism limits fluid losses via the underflow and is therefore conducive to the recycling of drilling mud additives, e. g. bentonite. As the separating behaviour of hydro vacuum cyclones cannot be predicted with the established calculation models for conventional hydrocyclones, in a group project involving the companies Herrenknecht AG, ITE GmbH, the Fraunhofer Institute for Environmental, Safety and Energy Technology UMSICHT and Osnabrück University of Applied Sciences, a 15" hydro vacuum cyclone was systematically studied under field conditions.
