Embodiment Construction

[0015] This device is suitable for large-area areas where oil slicks are quickly collected. It is generally installed on ships and used with high-power waste oil recovery systems.

[0016] Such as figure 1 or figure 2 As shown, an offshore oil slick collection device floats on the water surface, about 1 / 3 of which is above the water surface. The ultrasonic transducer 2 installed at the left and right baffles can emit ultrasonic waves with a frequency of 100K-300KHz. The ultrasonic waves drive the metal mesh cover 3 to vibrate to generate a large number of tiny bubbles. The oil droplet floats up to the surface of the fan blade 4 under the action of buoyancy, and the small oil droplet floats up to the oil delivery hole 5 through the “V” structure under the action of buoyancy. The oil delivery hole 5 is connected to the oil delivery pipe 1, and oil slick is recovered under the action of ship-borne power. Each rotation of the fan blade 4 is a complete treatment cycle. The fan ...

Abstract

The invention relates to a device for efficiently and rapidly removing floating oil, in particular to an offshore floating oil collecting device. An oil collecting system comprises a barrel-shaped floating oil collecting device body. An oil conveying pipe penetrates a center axis area of the device body. Ultrasonic transducers are installed at the positions of a left baffle and a right baffle. A metal screen is installed on the barrel surface of the barrel-shaped floating oil collecting device body. Fan blades are installed on the surface of the oil conveying pipe and in the metal screen. The ultrasonic technology is used for emulsifying the floating oil, small oil drops are gathered through an oil conveying hole of a V-shaped structure and are recovered, and the recovery efficiency is higher than that of a film treatment technology.

Description

technical field [0001] The invention relates to a device for efficiently and quickly cleaning oil slicks, in particular to an offshore oil slick collection device. Background technique [0002] There are many coastal ports in our country, and the pollution caused by oil spills from ships is becoming more and more serious. How to use clean and efficient methods to deal with marine pollution and solve the hazards of oil slicks at sea has become the focus of our research team. [0003] There are three main methods of oil slick collection at sea: chemical method, biological method and physical method. [0004] Chemical methods mainly use chemical agents to disperse or solidify oil spills, that is, to achieve the purpose of reducing pollution by changing the form of oil spills in the water environment. It is suitable for the situation where the oil film of the oil spill is very thin. [0005] The biological method is to remove the spilled oil through biological decomposition, a...
