Portable and modular waste liquid separator/collector device

one. A modular device for separating and collecting spent liquid, comprising the following constituent modules: support structure; droplet separator configured to connect to the support structure; and installation of a gutter for spent fluid; moreover, the component modules are made with the possibility of individual transfer. 2. The device according to claim 1, in which the supporting structure and the separator of the spent fluid are made with the possibility of folding relative to each other. The device according to claim 1, wherein the support structure comprises a frame and a base rotatably connected to the frame, the base being movable between a first position in which it is substantially parallel to the frame and a second position in which it is substantially perpendicular frame, and a fixing and stabilizing device for fixing and stabilizing the base and frame in said substantially perpendicular orientation. 4. The device according to claim 1, in which the supporting structure contains a separate frame and base made with the possibility of strong connection with each other so as to form a node containing a vertical frame and a horizontal base, and a fixing and stabilizing device for fixing and stabilizing the base and frame in essentially perpendicular to one another. 5. The device according to claim 3, in which the frame is essentially rectangular, containing two side rails and at least one transverse rail connecting the side rails, said support structure comprising two support rails connected to rotate between the ends respectively
