Hydrocarbon separator designed for treating runoff water

摘要

The hydrocarbon separator comprises a main box (11) internally defining a scrubber compartment and a separator compartment on both sides of a manhole (14) in the separator compartment with a well casing associated with the output flow and a vertically movable float and forming automatic shutter, and an output flow module (30) laid inside the main box. The output flow module comprises a base supporting a well casing and a float (32), and is arranged in one or the other of two different positions. A first position corresponds to a use of the separator with a bypass box (20). The hydrocarbon separator comprises a main box (11) internally defining a scrubber compartment and a separator compartment on both sides of a manhole (14) in the separator compartment with a well casing associated with the output flow and a vertically movable float and forming automatic shutter, and an output flow module (30) laid inside the main box. The output flow module comprises a base supporting a well casing and a float (32), and is arranged in one or the other of two different positions. A first position corresponds to a use of the separator with a bypass box (20) mounted externally as direct support on the main box, in which the casing contacts with an output compartment of the by-pass box and a second position corresponds to a use of the separator without bypass box. The casing contacts with an outlet hole of the main box. The two positions of the output module correspond transversely of 180[deg] without changing the height of the module in the main box. The main box has lateral guiding surfaces extending in a vertical direction. The surfaces used to guide the float during the vertical sliding in one and the other of two positions of the output module. The float has a cylindrical form. The lateral guiding surfaces have portions of vertical cylinders. The float is guided by a vertical profile mounted on the base of the output module, is maintained in either of two positions of the output module by a lateral guiding surface making a part of the main box and opposed by the vertical profile. The separator compartment of the main box has a terminal cell receiving and maintaining the base of the module based on the bottom of the main box, in one or either of two positions of the flow output module. The terminal cell of the main caisson has horizontal upper facets providing the vertical block of the base of the output module. The casing is constituted by a cylinder, of which the upper end is received in a hole associated with the lower wall of the by-pass box. In the second position of the module, the casing is constituted by the same cylinder then extended by a removable elbow, where the outlet end is received in outlet hole of the main box. The casing is mounted on the base of the module by sliding in a hole associated with the base to allow an eventual height adjustment of the casing. The base of the module is a hollow box of parallelepiped shape based on the bottom of the main box.
