Equipment for scale-removing, scale-proof and sterilizing for oil field waste water re-injection treatment system

The utility model relates to the equipment for scale-removing, scale-proof and sterilizing for oil field waste water re-injection treatment system, comprising an electrical control part, equipment structure part and a cable connection. The equipment for scale-removing, scale-proof and sterilizing for the oil field waste water re-injection treatment system is characterized in that the equipment structure part consists of a shell, a base, a supersonic energy exchanger, an ultraviolet sterilizer, a quartz casing, a shield cover, an end board, a sealing ring, a pushing cap, a sampling valve, a sensor, an inlet pipe, an outlet pipe and flanges. The equipment can remove and prevent the scale of the oil field waste water and a water injection system pipeline by the supersonic energy exchanger, and can also kill bacterium by the continuous irradiation of the ultraviolet. The ultrasonic can also continuously clean the surface of the screen of pollutants on the quartz casing, and the ultrasonic cavitation can increase the ultraviolet transmittance to achieve the scale-removing, scale-proof and sterilizing simultaneously; secondary pollution to the environment is avoided when a chemical method is adopted to remove and prevent the scale and kill the bacterium. The utility model has the advantages of simple structure, reliable performance and broad application.
