  • the water seal can be formed in a way where pre-heating of the liquid takes place, and contamination will be found at the surface of the water seal or maybe below the liquid. In that way a pre-treatment is possible.
  • the system can perform a filtration of the contaminated liquid in at least one filter. Filtration may be necessary in order to remove larger particles from the liquid because these particles later on in the process may cause stop of e.g. magnetic valves.

Abstract

La présente invention concerne un système ou un procédé conçus pour mettre en œuvre la purification d'un liquide contaminé (4), ledit système mettant en œuvre au moins un procédé d'évaporation du liquide contaminé (4), ladite évaporation étant mise en œuvre sous une pression négative (15). Une purification quasi-parfaite du liquide contaminé (4) est obtenue. Un autre objet de l'invention est d'éviter la formation de mousse au cours du procédé d'évaporation. L'objet peut être rempli si le système comprend au moins une enceinte (14, 101) de procédés commune, ladite enceinte (14, 101) de procédés comprenant une pluralité de fonctions techniques, telles qu'un dispositif chauffant (26), un évaporateur (18) et un condenseur (20, 105). Un système compact peut ainsi être obtenu, dans lequel la plupart des caractéristiques techniques sont placées dans la même enceinte (14, 101). Cette enceinte (14, 101) peut alors être en partie mise sous vide par une pompe (38, 102) de sorte qu'une pression négative commune (15) est obtenue dans l'enceinte (14, 101). Ainsi, le dispositif chauffant, l'évaporateur et le condenseur peuvent fonctionner sous une pression négative (15).
