METHOD AND DEVICE FOR REMOVING POLLUTION FROM A CONFINED ENVIRONMENTAbstractThe subject of the present invention is a method for removing pollution from a confined environment containing an interior space bounded by a wall, involving the following steps: the confined environment which has a leak is placed in a sealed chamber comprising means of introducing a gas and means of pumping a gas; the gas contained in the chamber and the gas contained inside the space are simultaneously pumped through the leak so that the pressure difference across the wall is always below a wall-damaging threshold. Another subject of the invention is a device for removing pollution from a confined environment comprising: a pollution removal chamber able to contain the confined environment; means of introducing a purging gas; means of pumping a gas with variable pumping capacity; means for controlling the pumping rate; means for monitoring the pressure difference between the inside and the outside of the environment.Figure 1
