A vapor/liquid contacting tray is disclosed which is useful in distillation, mass transfer and heat transfer processes where the liquid flows down and the vapor flows up through the vessel. In the device, the perforated area (1, 7) of the tray is relatively small, so the liquid is entrained upward. The liquid flow is directed downward into a large disengaging area (5). The downward momentum of the liquid and the large disengaging area (5) allow for high liquid and vapor flow rates without overloading the vapor/liquid disengaging capacity of the device. The device is also equipped with outlet weirs (3) and baffles (4) to deflect the flow of the vapor and liquid passing through the vessel.
L'invention concerne un plateau permettant de mettre en contact une vapeur et un liquide. Ce plateau est utile pour la distillation, les procédés de transfert de chaleur et de transfert de masse où le liquide descend et la vapeur monte à travers le récipient. Dans le présent dispositif, la surface perforée (1, 7) du plateau est relativement réduite, de sorte que le liquide est entraîné vers le haut. Le courant liquide est amené vers le bas dans une grande zone de séparation (5). La force d'impulsion du liquide vers le bas et la grande zone de séparation (5) permettent de traiter des courants de liquide et de vapeur à débit élevé sans pour autant surcharger la capacité de séparation vapeur/liquide du dispositif. Ce dispositif comprend également des tuyaux d'évacuation (3) et des chicanes (4) servant à dévier le courant de vapeur et de liquide traversant le récipient.
