A device for collecting and classifying leaked oil

Abstract

The invention discloses a device for collecting and classifying leaked oil, which belongs to the technical field of oil pollution cleaning on the water surface. The device includes: a separation processing component, which is arranged on a water surface moving component, and the separation processing component is extracted through an external liquid suction power part and a liquid transfer pipe The oil-liquid mixture on the water surface, the separation treatment component includes a treatment box, one side of the treatment box is provided with a mixed liquid inlet pipe connected to the liquid transfer pipe, and at least two inlet guide sleeves are arranged in the mixed liquid inlet pipe, and the two inlet guide sleeves The ports are round and of different sizes. The small end of the aperture is set at the end of the outlet direction of the oil-water mixture, and the large end of the aperture is set at the end of the flow direction of the oil-water mixture. The treatment box is equipped with a first oil-water separation chamber and a second oil-water separation chamber. chamber and drainage chamber. The invention promotes the rupture of the oil particle film through centrifugal separation and sedimentation separation to improve the oil particle coalescence effect to increase the recovery of leaked crude oil, and ensures the recovery of oil slicks with a particle size of less than 100 μm, reducing the pollution of the leaked crude oil to the environment and leakage loss.

Description

technical field [0001] The invention belongs to the technical field of oil pollution cleaning on the water surface, and in particular relates to a device for collecting and classifying leaked oil. Background technique [0002] According to incomplete statistics from 1977 to 2000, there have been 156 accidents involving oil spills from computing vessels around the world. The oil leaked into the sea every year accounts for about 0.5% of the world's crude oil production, which has caused great harm to human life, ecological environment, and economic development. Bad influence. More famous accidents such as: In 1989, an oil tanker of Exxon Petroleum Company hit a rock and sank when it sailed into Prince William Port, Alaska, USA, causing tens of thousands of tons of crude oil to leak. In the end, the cost of rescue and compensation for the accident was as high as 8 billion US dollars. Another example is that in November 2002, the oil tanker Prestige ran aground and sank in the ...

However, the use of chemical agents may cause new pollution to the ocean, and the large-scale use of chemical agents will greatly increase the cost of cleaning up pollution, so this method of cleaning up pollution is not widely used

Physical methods usually use fences to prevent oil from spreading, and then use oil suction machines to absorb oil, or put adsorbents on the sea surface to absorb oil. This method is not effective and inefficient; there are also large-scale mechanical collection methods. The cost of the method is too high, the energy consumption is too large, and the collection efficiency is low
