A system of self-purging centrifugal separators for the separation and clarification of liquids, especially heavy oil, which contain solids, has a first separator serving for preliminary separation and a second, clarifying separator connected to the output of the first. Each of these separators is purged of accumulated solids by means of associated controls, the second separator being additionally provided with an automatic purging control. The solids chamber of the clarifier drum is smaller than that of the drum of the first separator and the purging control communicates through a control line with an evaluator and the evaluator in turn communicates with the controls and/or with an alarm, whereby a premature disturbance due to the accumulation of sludge in the first separator is detected and eliminated by extra purges or is signaled by means of the alarm. |
