Leaked oil collecting and classifying device

Abstract

The invention discloses a leaked oil collecting and classifying device, and belongs to the technical field of water surface oil stain cleaning. The leaked oil collecting and classifying device comprises a separation treatment assembly, a water surface oil-liquid mixing body is extracted by the separation treatment assembly through an external liquid suction power piece and an external liquid transfer pipe, the separation treatment assembly comprises a treatment box body, a mixed liquid inlet pipe connected with the liquid transfer pipe is arranged on one side of the treatment box body, at least two inflow guide sleeves are arranged in the mixed liquid inlet pipe, two ports of each inflow guide sleeve are round and different in size, the small-hole-diameter end and the oil-water mixed liquid outflow direction end are arranged, and the large-hole-diameter end and the oil-water mixed liquid inflow direction end are arranged, and a first oil-water separation chamber, a second oil-water separation chamber and a liquid discharge chamber are arranged in the treatment box body. By means of centrifugal separation and settling separation, oil particle membrane rupture is promoted, so that the oil particle coalescence effect is improved, the recovery amount of leaked crude oil is increased, it is guaranteed that floating oil with the oil particle size smaller than 100 micrometers is recovered, and environmental pollution and leakage loss caused by the leaked crude oil are reduced.

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
