Offshore floating oil collecting device

Abstract

The invention provides an offshore floating oil collecting device. The device comprises a shell, a power device, a shovel type oil collecting device, a water pump, an oil-water separation tank and a control device; the power device is mounted on the shell, connected with the control device and used for providing power and buoyancy for the shell, and the shovel type oil collecting device is arranged at the front end of the shell and used for collecting floating oil; an oil outlet of the shovel type oil collecting device is connected with the oil-water separation tank through the water pump, the oil-water separation tank comprises a cabin for separating oil from water, and the cabin is provided with an oil outlet and a seawater discharge port; and floating oil collected by the shovel type oil collecting device is sucked into the oil-water separation tank through the water pump to be separated, and oil and water are respectively discharged from the oil outlet and the seawater discharge port. Leaked oil is treated through a physical method, an oil-water mixture is collected into the oil-water separation tank through the water pump to be preliminarily separated, the oil-water mixture is preliminarily separated through the oil-water separation tank and rapidly transferred to a cabin or a shore, and the leaked oil collection efficiency is high.

Description

technical field [0001] The invention relates to the technical field of offshore oil slick cleaning, in particular to an offshore oil slick collecting device. Background technique [0002] There are countless ports all over the world, and there will be many oil spills on ships. How to cleanly and efficiently deal with oil spill pollution at sea has become increasingly important. [0003] In addition to the traditional separation methods, there are four existing offshore oil spill collection devices, namely chemical method, combustion method, microbial method and physical method. The chemical method can use gelling agent, dispersant or demulsifier, etc. according to the dispersion state of the petroleum. Its essence is to transfer pollutants, but it still has certain toxicity and may cause new pollution, so it needs to be used with caution; the combustion method Directly burn the oil spilled at sea, the cost of treatment is low, but it has a great impact on the environment an...

Problems solved by technology

The chemical method can use gelling agent, dispersant or demulsifier, etc. according to the dispersion state of the petroleum. Its essence is to transfer pollutants, but it still has certain toxicity and may cause new pollution, so it needs to be used with caution; the combustion method Directly burn the oil spilled at sea, the cost of treatment is low, but it has a great impact on the environment and will cause a waste of energy; the microbial method mainly uses microorganisms to completely degrade petroleum hydrocarbons. This method is more environmentally friendly, but the removal time of this method is longer long and low efficiency; the physical method mainly uses the incompatibility of oil and water, collects the spilled oil and then concentrates it on the condition of not doing additional treatment on the spilled oil, and separates the oil and water without changing the form of the spilled oil. ideal method

[0004] Compared with the common oil spill treatment devices on the market, the following problems generally exist: 1) The oil spill collection devices mainly based on oil spill collection ships are too bulky; 2) The oil spill collection devices mainly based on small oil spill collection devices cannot Continuous work; 3) Part of the oil leakage collection device has no propulsion system; 4) It is easy to cause secondary pollution, etc.
