PROCESS AND INSTALLATION FOR THE SEPARATION OF SOLID-LIQUID-MIXTURES

摘要

The invention relates to processes for the separation, in particular filtration of liquids and solids from liquid-solid-mixtures, in particular from a mineral solid-liquid-suspension, preferably ore or coal suspension and sludge, respectively, of contaminated earth, the process space being submitted to overpressure, as well as to an installation for carrying out the process, consisting of a collector container for liquid-solid-mixture, in particular suspension, a pressure filter, a discharge system and container for condensate and solid matter. The invention is characterised primarily in that the separation, in particular filtration takes place in addition to the application of overpressure at elevated temperature, preferably 40.degree.C to 300.degree.C, conveniently 60.degree.C to 200.degree.C, preferably about 150.degree.C, and in that the pressure filter (2) communicates with a source forheated medium, respectively.
