Recovery treatment system and method for oil field waste filtered substance

Abstract

The oil field waste filter material recovery treatment device system and its recovery treatment method relate to a system and method for recovery treatment of waste filter material. Now the waste filter material in the oil field pollutes the environment and wastes resources. The processing system of the present invention is: the coarse screening machine (1) is connected with the screw elevator (2), the outlet of the filter material cleaning treatment device (3) is arranged above the hopper of the screw elevator separator (4), and the drying box (5) Connected with the conveyor belt (6), the magnetic separator (7) is connected with the conveyor belt (6) and the multi-layer electric screening machine (8). The method of the present invention is that the waste filter material enters the coarse screening machine (1), the screw elevator (2), and the filter material cleaning treatment device (3) in sequence, and is separated by the spiral lifting after rinsing in the filter material cleaning treatment device (3). The machine (4) is lifted and enters the drying box (5), and the classified filter material is sent to the screening machine (8). Through the processing system and processing method of the present invention, production funds are saved and environmental pollution is avoided.

Description

Technical field: [0001] The invention relates to a system and method for recycling waste filter materials on oil fields. Background technique: [0002] At present, in order to ensure that the effluent water quality reaches the oilfield reinjection water quality index, the current oilfield sewage treatment adopts the method of sedimentation and filtration. The filtration method mainly uses granular filter materials to intercept suspended solid particles and dirty oil. The filter material used in the filter equipment is usually replaced every 2 to 3 years, and the replaced filter material is generally disposed of by transporting and burying. Since the replaced filter material contains a large amount of polluting impurities and dirty oil, it will pollute the environment; in addition, if the replaced filter material cannot be reused and discarded, it will waste resources. Therefore, in view of this situation, the research on waste filter material treatment and reuse technology ...
