Abstract

The invention provides a self-overflow type graphene oily sewage treatment device. A tank is a horizontal cylindrical sealed container, and a nitrogen inlet is formed in the top of the sealed container; an oily sewage inlet is connected with an oil-water separation cavity; a water distribution pipe is arranged at the periphery of an upper part of the oil-water separation cavity; a plurality of water spray pipes are uniformly distributed on the water distribution pipe; a primary oil collection cavity is formed in the right side of the oil-water separation cavity, and a baffle is arranged between the oil-water separation cavity and the oil collection cavity; a sewage cavity is formed in the right side of the oil collection cavity, and a water production cavity is formed in the right side of the sewage cavity; the water distribution pipe is arranged between the sewage cavity and the water production cavity, and water spray pipes are arranged on the water distribution pipe; a graphene based mesh film is distributed on the upper part of the water production cavity and below the water spray pipe; an oil collection tank is arranged at the tail part of the graphene based mesh film; an opening is formed in the bottom of the oil collection tank and is connected with a secondary oil collection cavity; and a dirty oil outlet is formed in the bottom of the oil collection cavity. The device disclosed by the invention has the advantages of high oil removal efficiency, small floor space, high pollution resistance, broad water inlet quality requirement, capacity of well adapting to oilfield sewage conditions and simple matching treatment process flow.

Description

technical field [0001] The invention relates to the technical field of oil production sewage treatment in oil fields, in particular to a device for removing oil and suspended matter from oil production sewage. Background technique [0002] With the diversification of reservoir development methods, the continuous application of new oil recovery technologies, and the continuous improvement of the recovery rate, the production fluid is becoming more and more complex, the production water is increasing, and the treatment difficulty is increasing. The adaptability of oil removal + two-stage filtration” process needs to be further improved. [0003] At present, gravity degreasing facilities commonly used in oily sewage treatment systems have problems such as low degreasing efficiency and large floor area. Commonly used filtration equipment includes walnut shell filter, emery filter, double filter material filter, multi-media filter, etc., but these filters have high requirements ...
