Description

Arm-type oil collecting device with self-cleaning function

Technical Field

The utility model relates to an oil collecting device, specific arm-type oil collecting device that has self-cleaning function that can prevent that ageing oil from hindering, blockking up oil collecting pipe that says so.

Background

At present, the oil recovery process of a settling tank in each large oil field is fixed oil recovery, a fixed oil recovery tank is installed at the upper part of the settling tank, and when the liquid level in the settling tank reaches a certain height, namely the oil level of the upper layer reaches or exceeds the height of the oil recovery tank, an oil layer automatically flows into an oil recovery pipeline from the oil recovery tank and is conveyed to an in-station dehydration system through an oil recovery pump for next treatment. The oil receiving mode can realize oil receiving only when the liquid level reaches or exceeds the height of the oil receiving tank.

Because the oil collecting device with the structure can not realize continuous oil collection at present, the retention time of dirty oil in the oil tank is longer, aging oil is easily formed in the oil tank, and certain harm is generated to the dehydration and sewage system treatment. The aging oil is generated particularly because a part of 50-500nm solid particles in the crude oil in the settling tank contain colloid, asphaltene and other heavy components and solid impurities which are higher than those of the common crude oil, and are adsorbed on an oil-water interface. The colloid formed by the solid particles and the asphaltene has certain stability and is not easy to collect and utilize, and is generally called aging oil.

The aged dead oil has high viscosity and contains more sulfides, so the aged dead oil has serious corrosion to a system, is easy to be retained in an oil collecting pipeline and an oil collecting pump, leads to difficult starting of the oil collecting pump, and influences the continuity and stability of oil collecting work.

In conclusion, the aged oil becomes a key to prevent continuous oil recovery.
