DEVICE FOR SEPARATING TWO ZONES WITH DIFFERENT ENVIRONMENT

摘要

The invention concerns a device for separating (100) a first (10) from a second zone (20) in which prevails different kinds of environment. The invention is characterised in that it comprises: a buffer zone (110) extending along a longitudinal axis X between the first and second zones, and communicating via an inlet (111) with the first zone (10), and via an outlet (112) with the second zone (20); means for injecting air (120, 120a) opening at the inlet of the buffer zone, for injecting on either side of said longitudinal axis X, towards the outlet of said buffer zone, two clean air jets (121, 122) at high speed, extending along oblique directions (Y1, Y2) relative to the axis X, which cross each other in a region between the inlet and the central region (113) of said buffer zone, so as to form an impassable barrier which separates the first from the second zone.
