Patent ID: 7422683

Claim:
A vortex separator for separating floating and settling substances from inflowing storm-water, comprising: a separation casing; a guide plate provided in the separation casing and supported by a connection plate coupled to the inner surface of the separation casing for preventing untreated storm-water from being prematurely discharged from the separation casing; an inlet pipe coupled to the guide plate at a position below the connection plate and extending outside the separation casing, so that the storm-water is drawn into the guide plate through the inlet pipe; a perforated inclined skirt provided below the guide plate to guide the settling substances to a bottom of a sediment storage chamber and to prevent the settling substances from being resuspended; and an outlet pipe coupled to the separation casing at a position below the connection plate and extending outside the separation casing, so that storm-water is discharged through the outlet pipe.
