Water face thin oil film recycling and separating device

Abstract

The invention discloses a water face thin oil film recycling and separating device. The device comprises a boat body, wherein the boat body is provided with a main runner enabling oily water to enter and pass; a propelling device is arranged on a stern; an adjustment cofferdam is arranged on the front section, which is inclined like a minus grade, of the main runner; two adjacent separation cabins are arranged on the boat body; the front end of the primary separation cabin is communicated with the external oily water by the inlet of the main runner; a discharge hole at the rear end of the cabin is communicated with the main runner; guide plates are respectively arranged on the bottom of the secondary separation cabin and inside the secondary separation cabin; the two guide plates are used for forming an inertia cabin used for secondary oil and water separation in the rear of the secondary separation cabin; a rotating flashboard and a guide plate are arranged on the rear end of the discharge hole of the primary separation cabin; the rotating flashboard can obstruct or open the main runner, and can form a transition runner of the oily water when the main runner is obstructed, together with the guide plate at the rear end of the discharge hole of the primary separation cabin and the guide plates on the secondary separation cabin; the two separation cabins are connected with a recovery cabin by suction pipelines; oil level sensors are arranged on the separation cabins. The water face thin oil film recycling and separating device is used for effectively recycling and separating large-area or local regional thin oil film on the water face.

Description

technical field [0001] The invention relates to the technical field of oil spill recovery and treatment in water areas, in particular to a device for recovering and separating thin oil films on or near the water surface. Background technique [0002] In the surface oil spill emergency treatment technology, the oil slick recovery ship is the most important equipment in this field. Chinese patent CN00256382.7 discloses an oil slick recovery ship, which includes a hull and an oil skimmer, wherein the front deck of the hull has a groove, the front end of the groove is open, and the oil skimmer is installed in the groove , a diversion pump is installed on the inner side of the lower end of the oil skimmer. When recovering the oil spill, turn on the diversion pump, and the water surface will counteract the effect of the bow wave, and quickly lead the spilled oil to the oil recovery zone, which is in the shape of a grid Oil filter and oil recovery belt, water can leak from the gri...

Chinese patent CN00256382.7 discloses an oil slick recovery ship, which includes a hull and an oil skimmer, wherein the front deck of the hull has a groove, the front end of the groove is open, and the oil skimmer is installed in the groove , a diversion pump is installed on the inner side of the lower end of the oil skimmer. When recovering the oil spill, turn on the diversion pump, and the water surface will counteract the effect of the bow wave, and quickly lead the spilled oil to the oil recovery zone, which is in the shape of a grid Oil filter and oil recovery belt, water can leak from the grid, and oil adheres to the oil recovery belt, which greatly improves the recovery rate of oil spilled, but because the oil recovery belt is used to collect oil, there is a requirement for the viscosity of the slick oil, for those For relatively thin oil slicks, the effect of oil collection with oil collection belt is not good, and the oil sweeping surface is small

For other types of oil collection equipment in the prior art, such as rotary table oil collection equipment, because it relies on the surface of the disk to collect oil, it is only suitable for recovering medium and high viscosity oil spills. , the water content is relatively large, and oil-water separation equipment is required for secondary treatment, and the efficiency is low
