A magnetic fluid sea surface thin oil film recovery and separation device

Abstract

The invention discloses a magnetic fluid sea surface thin oil reclaiming and separating device. A magnetic fluid passage (5) penetrates through a magnetic hole of a magnet (6); the front part of the magnetic fluid passage is connected with a duckbill sucking pipe (4); the rear part of the magnetic fluid passage is sequentially connected with an oil and water separating tank (7), an opened filtering box (8) and a spraying pipe (11); an idler wheel oil skimmer (3), a garbage net fence (2) and a flow guide door sill (1) are sequentially arranged on the front part of the duckbill sucking pipe (4); the flow guide door sill (1) is arranged at the most front end of a ship body (12); the garbage net fence (2) and the idler wheel oil skimmer (3) are arranged in a channel in the front part of the ship body (12); the duckbill sucking pipe (4) is arranged on the lower part of a cabin arc front end plate, matched with the circular outer hub surface of the idler wheel oil skimmer (3), at the tail end of the channel in the front part of the ship body (12); the duckbill sucking pipe (4) penetrates into a cabin of the ship body (12) to be connected with the magnetic fluid passage (5); the magnet (6), the oil and water separating tank (7) and the opened filtering box (8) are arranged in the cabin of the ship body (12); the spraying pipe (11) is embedded in the ship stern plate of the ship body (12).

Description

technical field [0001] The invention relates to a marine oil spill disposal device, in particular to a recovery and separation device suitable for oil films with a thickness below the millimeter level. Background technique [0002] In the emergency treatment of marine oil spills, the oil layer with a thickness of 1-10 mm is usually called thin oil layer. According to the Bonn agreement, the oil layer with a thickness of less than 1mm is an oil film. The pollution and leakage of thin oil layers on the sea surface, the pollution and leakage of chemical raw materials, and the oil film formed by light oil, condensate oil, and oily sewage, etc., have become the most difficult problem of marine oil spill pollution due to their thin thickness, poor continuity, and large oil-water and oil-gas interfaces. Chinese patent 02142835.2 discloses a method and device for recovering oil slicks on the sea surface by magnetohydrodynamics, which realizes the recovery and separation of thin oil...

AI Technical Summary

Problems solved by technology

In the above-mentioned method and device for recovering floating oil on the sea surface by magnetic fluid power, the magnetic fluid channel is placed horizontally, and the static pressure gradually increases from the entrance to the outlet of the magnetic fluid channel, which is not conducive to the discharge of air bubbles, so that the air bubbles gather in the upper part of the magnetic fluid channel The space and entrance affect the floating oil entering the magnetic fluid channel and its flow in the magnetic fluid channel, which in turn affects the recovery and separation effect of the floating oil
