Self-overflow type graphene oily sewage treatment device

Abstract

The invention provides a self-overflow type graphene oily sewage treatment device, wherein the tank body is a horizontal cylindrical sealed container with a nitrogen inlet on the top; the oily sewage inlet is connected to the oil-water separation chamber, and the upper part of the oil-water separation chamber is surrounded by There are water distribution pipes, and multiple water spray pipes are evenly distributed on the water distribution pipes; the right side of the oil-water separation chamber is the first-level oil collection chamber, and a baffle is set between the oil-water separation chamber and the oil collection chamber; the right side of the oil collection chamber is Sewage chamber, the right side of the sewage chamber is the water production chamber; there is a water distribution pipe between the sewage chamber and the water production chamber, and a water spray pipe is opened on the water distribution pipe; the upper part of the water production chamber and the lower part of the water spray pipe are covered with graphene The end of the graphene-based membrane is provided with an oil collection tank; the bottom of the oil collection tank is provided with an opening, which is connected to the secondary oil collection chamber, and the bottom of the oil collection chamber has a dirty oil outlet; the advantages are: high oil removal efficiency , small footprint, strong pollution resistance, wide requirements for influent water quality, can well adapt to the working conditions of oilfield sewage, and the supporting treatment process is simple.

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 ...
