Abstract

L’invention concerne un dispositif relatif à la fameuse « expérience du vide de Torricelli », dans lequel s’écoule un liquide. Ce dispositif peut établir un état de vide par intermittence avec la force gravitationnelle au moyen d’un liquide, de l’atmosphère et de tuyaux. Le liquide utilisé peut être soumis à des évacuations continues. Une soupape (4) est fermée pour remplir un tuyau de réduction de pression (1), un tuyau de remplissage (2) et un tuyau d’évacuation (3) avec le liquide. Ensuite, la soupape (4) est ouverte pour établir un vide dans la partie supérieure du tuyau de réduction de pression. Le liquide est fourni en continu par une pompe (5), afin d’être évacué de manière continue. Si le gaz s’accumule dans le tuyau de réduction de pression pendant le fonctionnement continu, si bien que le vide diminue, la soupape (4) est à nouveau fermée pour introduire le liquide et l’évacuer. Ces opérations sont répétées. En fonction de l’objectif, le dispositif fonctionne non seulement avec un liquide présentant une viscosité élevée, mais également avec un liquide présentant des contenus solides. En modifiant les caractéristiques et en ajoutant les dispositifs nécessaires pour l’objectif souhaité, le dispositif peut également être utilisé pour les opérations d’épuration des eaux usées, de refroidissement, d’imprégnation sous vide, de dégazage sous vide, de distillation sous vide ou similaires.
