Oil containment backwater bay

Abstract

The invention provides an oil containment backwater bay, which can solve the problem that the oil baffling effect is poor because spilled oil is easy to flow from a junction of an oil containment boom which is obliquely arranged and a water bank when a flow rate of water is relatively high in the prior art. The oil containment backwater bay comprises the oil containment boom and a water channel, wherein the oil containment boom spans between two banks; the backwater bay is dug at one bank at one downriver end of the oil containment boom; the backwater bay is provided with a water bay port communicated with the water channel; the water bay port comprises an upriver side edge and a downriver opening side edge; and the upriver end of the oil containment boom is fixedly arranged at the bank on the other side. Because an oil flow passage primarily stopped by the water banks is extended and is far away from a main water flow, the oil baffled by the oil containment boom does not stop at the water banks and is not taken away by a vortex but smoothly enters the water surface centre of the backwater bay with a centrifugation function. Thus, the problem of oil leakage at the junction of the oil containment boom and the water bank is solved.

Description

technical field [0001] The invention belongs to the field of oil spill recovery on the water surface, and in particular relates to an oil-wrapped water bay. Background technique [0002] In the field of surface oil spill recovery, the oil boom is the main tool to prevent the spread of oil spills. When the oil boom is deployed, its length direction is generally perpendicular to the direction of water flow, and the oil boom intercepts the oil spill vertically. However, the critical flow velocity V of the oil spill can be stopped by the oil boom. 临 The oil boom researchers at home and abroad pointed out that the critical flow velocity V of this water flow is very low. 临 It is only 0.7-1.0 knots (about 0.35-0.5m / s), and most of the oil boom researchers believe that it is only 0.7 knots. If the water flow velocity V is higher than this value, because the water flow velocity V is too high, the oil layer will follow the water flow to the bottom of the oil boom and flow to the oth...

Problems solved by technology

[0004] The invention provides an oil-enclosing water bay, which can solve the problem in the prior art that oil spills are easily lost from the intersection of the oil containment boom and the water bank when the oil containment boom slant cloth is used when the water flow velocity is relatively high, resulting in poor oil blocking effect
