摘要 |
The invention relates to a process for the separation, preferably filtration, of liquids and solids from solid-liquid mixtures, in particular from a mineral solid-liquid suspension, preferably ore or coal suspension or slurry from contaminated soil, the process space being at superatmospheric pressure, and relates to an installation for carrying out the process, comprising a liquid-solid mixture reservoir, in particular suspension reservoir, a pressure filter, a discharge system and vessel for condensate and solid. The invention is especially characterised in that the separation, in particular filtration, in addition to the use of superatmospheric pressure, takes place at elevated temperature, for example 40@C to 300@C, expediently 60@C to 200@C, preferably approximately 150@C and in that the pressure filter (2) is connected to a source for heated medium. <IMAGE>
