Title:
MANHOLE HAVING OIL-WATER SEPARATION FUNCTION
Document Type and Number:
WIPO Patent Application WO/2017/213350
Kind Code:
A1
Abstract:
The present invention relates to a manhole having an oil-water separation function, with the aim of spontaneously introducing external air into an inflow induction pipe downwardly extending from the manhole to allow for the simple separation of wastewater into oil and water (sewage) and to conveniently apply the manhole to places where oil and sewage are arbitrarily generated, including detached houses, multi-unit houses, parking lots, gas stations, roads, and the like. The present invention is designed to have an inflow induction pipe installed inside of an inflow pipe of a manhole body. According to the present invention, when wastewater containing oil and domestic sewage flows into the manhole, a vortex phenomenon that occurs with the inflow of the wastewater into the inflow induction pipe allows for the induction of external air into the inflow induction pipe to separate the wastewater into oil and sewage by specific gravity. Further, when the oil accumulates, as it inflows, and is solidified into a lump due to the viscosity thereof, a lid of the manhole is removed and the oil lump can be taken out and collected. Therefore, the present invention is convenient for use.
