摘要

System for the control of the evacuation of pollutants in boats, essentially characterized by the fact that they comprise collecting tanks for the waters to be evacuated and contaminated with hydrocarbons and a discharge mouth of the same at sea, connected to each other by a conduction in the that a hydrocarbon separating device and a booster pump of the waters towards the sea are interspersed, and, upstream of said mouth, a regulating valve of passage, from whose side of entry a branch that recycles at least a fraction of the flow part discharge to the upstream end of the separating device, said bypass valve being governed by drive means which, in turn, are subordinated to the control signal of a unit detecting the presence of hydrocarbons and which analyzes at least one fraction of the discharge flow, the conditions being such that the valve tends to close from a pretest detection limit established in relation to the total discharge flow and the speed of the ship.
