Abstract

The invention is a reclaiming system and method for oil field waste filter material. The oil waste will contaminate environment and wastes resources. The system is: a coarse sifter is connected to a spiral elevator, the outlet of the filter rinsing process device is arranged above the spiral elevating separator, the drying box is connected to the transmission belt, and the magnetism separator is connected to the transmission belt and multi-layer electric sifter. The method is: the waste material passes through the coarse sifter, spiral elevator, filter rinsing device, the material is rinsed in the device and then it is elevated by the elevating separator, enters the drying box.

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 ...
