Shipborne spilled-oil recycling system based on gas floating spilled oil separation

Abstract

The invention relates to a shipborne spilled-oil recycling system based on gas floating spilled oil separation.The system comprises an oil receiving machine, an oil-water separation unit, a gas floating unit and a waste oil bin.The gas floating unit is composed of a buoy and a gas floating contact area, and the oil receiving machine is provided with an overflow weir adjusting plate.The oil-water separation unit comprises an oil-water separation area, and a water inlet pipe connector is arranged at the front end of the oil-water separation unit and connected with the oil receiving machine.A gas floating release port is connected with an outlet of a multi-phase medium pump.The gas floating contact area is separated from the oil-water separation area through an inclined plate.An oil partition board and a water dividing plate are arranged on the rear middle section of the oil-water separation unit.The rear portion of the oil-water separation unit is provided with a backflow water outlet connected with an inlet of the multi-phase medium pump.An oil storage tank is arranged on the oil receiving machine.The oil-water separation unit is provided with an oil discharge pipe and a drainage pipe, and the waste oil bin is connected with the oil discharge pipe.The system can increase the oil content of recycled spilled oil, the waste oil bin can be used to the largest extent, and when the system is used on a ship, the number of round trips of the ship is reduced, and oil recycling efficiency is improved.

Description

technical field [0001] The invention belongs to the technical field of environmental emergency and relates to a shipborne oil spill recovery system based on air floatation oil spill separation. Background technique [0002] At present, offshore oil production and transportation have led to an increasing number of oil spill accidents, causing serious water pollution and ecological environment damage, and gradually endangering human life and health. This has also brought the issue of oil pollution into the public eye. Over the years, a variety of methods have been developed for oil spill disposal. Among them, physical recovery, controllable combustion, and spraying of oil dispersants are commonly used. Among them, physical recovery can not only recover energy but also avoid secondary pollution. Preferred method of disposal. The physical recovery facilities of oil spill mainly include weir type, rotary table type, brush type, rope type and dynamic slope type oil skimmer, etc. ...

AI Technical Summary

Problems solved by technology

In general, the drum type, disc type and brush type oil skimmers have higher oil recovery concentration, but have the defect of low recovery rate, while the oil recovery rate of weir type and dynamic slope type oil skimmers has been improved. , but the water content in recovered spilled oil is greatly increased

Especially when the amount of oil spilled is small or the wind and waves are strong, the moisture content of the spilled oil recovered by various oil skimmers is high, occupying the limited storage space of the oil spilled recovery ship, increasing the number of round trips of the ship, which is not conducive to the recovery of spilled oil. Rapid recovery of oil
