Floating circular current oil receiver and circular current separating method

Abstract

Floating circulation oil collector and circulation separation method are suitable for on-site treatment of oily sewage in oil exploration, collection, storage and transportation, processing and other petrochemical processes; pre-treatment of oily sewage treatment plants, replacing oil separation, air flotation and other mixing with different specific gravity Separation and removal of liquids. The oil collection tank is connected with the ring pipe, and the lower part is provided with a support rod; the oil collection bucket in the oil collection ring at the upper part of the oil collection tank is connected with the oil outlet pipe; the water outlet of the oil collection tank at the lower part of the oil collection tank is connected with the peripheral pumping equipment; the lower part of the container is provided with a water outlet pipe; An oil collection tank buoy is arranged on the outer surface of the oil collection tank; a buoy, a ring pipe buoy and a water injection pipe are arranged on the ring pipe; the water inlet pipe system is connected with the ring pipe; the ring pipe matches the pulley on the guide rod. The circulation separation method is: the oily sewage enters the water inlet pipe system from the water inlet, so that the floating oil on the liquid surface flows to the oil collection tank and the oil collection bucket, and is discharged through the oil outlet pipe; the separated clean water is discharged from the water outlet pipe; the water outlet and The peripheral pumping equipment is connected to form a circulation loop and reciprocate. It has the advantages of saving energy and reducing land occupation.

Description

technical field [0001] The invention relates to a floating circulation oil collector and a circulation separation method, which is especially suitable for in-situ treatment of oily sewage in oil exploration, collection, storage and transportation, processing and other petrochemical processes; the pretreatment of oily sewage treatment plants replaces oil separation, Separation and removal of air flotation and other mixed liquids with different specific gravity. Background technique [0002] At present, the sewage degreasing technology in the domestic existing technology is mainly based on the treatment process of gravity separation, which generally consists of the "old three sets" of processes such as adjustment, oil separation, and air flotation. [0003] In the process of oil exploration, collection, storage and transportation, refining and other petrochemical processing, there are containers for different purposes, including tanks and pools, in the process of oily sewage c...

AI Technical Summary

Problems solved by technology

[0008] 2. Multi-layer outlets can also be used to reduce the high water level, but due to the floating liquid level, the position of the oil-water interface cannot be determined, and the operation is difficult;

[0009] 3. There are also facilities that use floating funnels to collect oil, but due to the huge water surface, the floating oil has no moving power, so the effect is limited

However, due to its harsh operating conditions, high energy consumption and operating costs, it is difficult to promote, so it cannot replace the status of the traditional "old three sets" so far
