Abstract
Le procédé d'épuration d'eaux polluées consiste à introduire dans un filtre (7) une quantité spécifique d'eau à épurer, à filtrer cette eau afin d'obtenir une eau partiellement épurée, à accumuler de l'eau partiellement épurée dans un espace restreint (9a) afin d'y recueillir un volume d'eau (12), à chauffer (10) l'eau partiellement épurée à une température voisine de son point d'ébullition, à réintroduire l'eau partiellement épurée dans le même filtre, et à répéter de façon continue les étapes de filtrage, d'accumulation et de chauffage de l'eau partiellement épurée, accompagnées d'une épuration supplémentaire de l'eau partiellement épurée jusqu'à ce que le niveau de pollution de cette eau soit tombé en dessous d'un niveau choisi. Une partie prédéterminée du volume d'eau épurée peut être distillée (43) après achèvement de l'épuration, et l'eau distillée est recueillie (46) dans un réservoir (45) en vue de sa consommation ultérieure. Un dispositif pour la mise en oeuvre du procédé décrit comprend un récipient (9) muni d'un filtre (7) disposé dans sa partie supérieure (20) délimitant une chambre de stockage dans sa partie inférieure (9a), et un couvercle (3) qui est supporté par le récipient de manière amovible. Une résistance électrique de chauffage (10) est disposée soit dans la chambre de stockage (Fig. 1) soit à l'extérieur du récipient (Fig. 2), et un tuyau montant (16), pouvant comporter dans sa partie inférieure une poche pour recueillir la vapeur, monte depuis la résistance de chauffage jusqu'au filtre. Le récipient peut être installé dans une enceinte (45) de condensation de vapeur pour produire de l'eau distillée (46) et être mis en communication avec cette enceinte.The process for purifying polluted water consists in introducing into a filter (7) a specific quantity of water to be purified, in filtering this water in order to obtain partially purified water, in accumulating partially purified water in a restricted space (9a) in order to collect a volume of water therein (12), to heat (10) the partially purified water to a temperature close to its boiling point, to reintroduce the partially purified water in the same filter, and continuously repeating the steps of filtering, accumulating and heating partially purified water, accompanied by additional purification of the partially purified water until the level of pollution of this water has fallen below a chosen level. A predetermined part of the volume of purified water can be distilled (43) after completion of the purification, and the distilled water is collected (46) in a tank (45) for later consumption. A device for implementing the described method comprises a container (9) provided with a filter (7) arranged in its upper part (20) delimiting a storage chamber in its lower part (9a), and a cover (3 ) which is removably supported by the container. An electric heating resistor (10) is disposed either in the storage chamber (Fig. 1) or outside the container (Fig. 2), and a rising pipe (16), which may include in its lower part a pocket to collect the steam, go up from the heating resistance to the filter. The container can be installed in a vapor condensation enclosure (45) to produce distilled water (46) and be placed in communication with this enclosure.
