PROCEDE ET DISPOSITIF DE CONFINEMENT, NOTAMMENT D'UNE ATMOSPHERE PARTICULIERE DANS UN ESPACE DE TRAITEMENT EN CONTINU DE PRODUITS TRAVERSANTS |
摘要 |
A method for confining an atmosphere (B) in a space (4) communicating with its surroundings via at least one opening. A gas curtain (1 + 2) comprising a low-velocity jet (2) and a high-velocity jet (1) is generated at said opening. A fraction of the flow in said low-velocity jet (2) is injected into the confined atmosphere (B) and adds to the induced flow rate of said low-velocity jet (2), the size of said fraction being variable depending on the pressure within said space (4). A device for carrying out the method is also disclosed. |
