preparation example Construction

[0071] Preparation of dearomatized petroleum ether: 60-100 mesh coarse-porous microsphere silica gel and 70-120 mesh neutral chromatographic alumina (activated at 150-160°C for 4 hours) were loaded by column chromatography before complete cooling into a glass column with an inner diameter of 25 mm and a height of 750 mm. The lower layer of silica gel is 600mm high and covered with 50mm thick alumina. Commercially available petroleum ether (60-90°C fraction) is passed through this column to remove aromatics. Collect petroleum ether in a narrow-mouthed bottle, and use water as a reference at 225 nm on an ultraviolet spectrophotometer to measure the light transmittance of the treated petroleum ether so that it should not be less than 80%.

[0072] standard curve drawing

[0073] Add 0, 2.00, 4.00, 8.00, 12.00, 20.00 and 25.00mL of standard oil solution to seven 50mL volumetric flasks, and dilute to the mark with petroleum ether (60-90°C). On an ultraviolet spectrophotometer, at...

preparation Embodiment 1

[0079] This example is used to illustrate the preparation of the coated silica sand coated with an oleophilic and hydrophobic film on the surface provided by the present invention.

[0080] Heat 3kg of quartz sand particles (density 1.65g / cm3) with an average particle diameter of 0.4mm to 250°C and put them in a sand mixer for stirring. After that, cool down to 200°C and add polyamide resin modified epoxy resin 0.15kg, fully stirred, so that the resin is evenly distributed on the outer surface of the quartz sand particles, then add aliphatic amine curing agent (the weight ratio of curing agent to resin is 2:100) to solidify, and finally cool to room temperature, crush to obtain a coating Silica sand (coating thickness 1-2 microns). The sphericity of the obtained coated silica sand is 0.72, and the particle diameter distribution is 320-450 microns.

preparation Embodiment 2

[0082] This example is used to illustrate the preparation of the coated silica sand coated with an oleophilic and hydrophobic film on the surface provided by the present invention.

[0083] Prepare coated particles according to the same method as Preparation Example 1, the difference is that a phthalate plasticizer is added before adding the curing agent, and its weight ratio to the resin is 10: 100, and fully stirred to obtain The cladding layer thickness of the coated silica sand is 2-3 microns, the sphericity is 0.75, and the particle diameter distribution is 350-430 microns.

Abstract

The invention provides a method for collecting floating oil on a water surface. In the method, an oil-water separation device is provided, wherein the device comprises an oil collecting cavity (2) defined by a wall (1), at least partial surface of the wall (1) is covered with a porous oleophylic hydrophobic layer (3), the part of the wall (1), covered with the porous oleophylic hydrophobic layer (3), allows water and oil to pass through, the device also comprises a fixing layer (4) which is covered on the surface or above the porous oleophylic hydrophobic layer (3) and is used for limiting the flowing of the porous oleophylic hydrophobic layer, and the fixing layer (4) allows the water and the oil to pass through, the hole diameter of the porous oleophylic hydrophobic layer (3) is 300 to 850mu, and the porosity is 10 to 40%; the oil-water separation device is placed on the water surface with the floating oil such that the at least partial surface of the fixing layer (4), which is covered on the surface or above the porous oleophylic hydrophobic layer (3) and is used for limiting the flowing of the porous oleophylic hydrophobic layer, is in contact with the water surface with the floating oil; and then the floating oil in the oil collecting cavity is collected. By means of the method provided by the invention, a large area of floating oil on the sea can be effectively collectedand the efficiency of collecting the floating oil is remarkably improved.

Description

technical field [0001] The invention relates to a method for collecting floating oil on the water surface. Background technique [0002] The world's oil mainly relies on sea transportation, and oil tankers running aground, colliding, running aground, and destroying the structure of the hull itself will cause serious oil spill accidents. At the same time, more and more offshore drilling platforms and offshore oil pipelines have been built one after another, and there are also hidden dangers to the environment or their own structures, which will lead to offshore oil spills and large-scale floating on the sea. Therefore, by means of effective sea oil slick recovery methods, relying on advanced sea surface oil slick recovery devices can minimize its negative impact. [0003] The existing oil slick collection device can play the role of collecting and treating the oil slick on water with small area and less liquid volume, but it is not suitable for dealing with a large amount of...
