Abstract

The invention provides a gas supply oxygenation micro-oxidation device of an oilfield water injection system. Relates to the technical field of aeration. A top opening of the reaction box is connected with a ventilation pipe, and a fan is installed in the ventilation pipe and connected with a stirring shaft. The aeration device has the following beneficial effects that the aeration plate aerates sewage on the sewage overflowing area, the aeration area is increased, no dead angle is left in sewage aeration, the sewage subjected to sufficient aeration returns upwards again to flow into the space where the stirring paddle is located, and the stirring paddle utilizes air flow discharged upwards from the ventilation pipe as power, so that the aeration effect is improved. Large bubbles gathered in flowing sewage are cut and crushed, small bubbles formed after crushing and the sewage form a micro-oxidation reaction, the aeration efficiency is further improved, the blades are driven to rotate through wind power, the stirring shaft is driven to rotate, and the stirring strength is improved through natural wind power.

Description

Technical field: [0001] The invention relates to the technical field of aeration, in particular to an air supply oxygen increasing micro-oxidation device for an oil field water injection system. Background technique: [0002] When the oil field water injection system is injected with sewage, the sewage contains a large amount of reducing substances. If it is directly used to dissolve the polymer without treatment, the reducing substances in the water will partially oxidize and degrade the polymer, reduce the viscosity of the injection fluid, and increase The amount of polymer used affects the effect of geological development. At present, the water injection system mostly uses Roots fan air supply and oxygenation device to oxygenate the sewage, and the compressed air is supplied to the aeration head laid on the bottom of the reaction tank for aeration to increase the dissolved oxygen in the water body. In such an aeration method, the time for the bubbles to rise from the bott...
