an integrated high-efficiency filter material circulating cleaning and filtering device for oilfield produced water comprises a filtering tank body, wherein the top of the filtering tank body is provided with a water inlet, the bottom of the filtering tank body is provided with a water outlet, and a group of filtering components are arranged in the filtering tank body and used for filtering oilfield produced water;

the bottom of the filter tank body is also connected with a backwashing pipe, the backwashing pipe extends into the filter tank body, an outlet of the backwashing pipe is arranged right against the bottom of the filter assembly, a cleaning port which is right against the filter assembly is also arranged on the side wall of the filter tank body, the cleaning port is connected with a scrubbing circulation assembly through a pipeline, and the scrubbing circulation assembly is arranged outside the filter tank body and is used for cleaning and regenerating the filter assembly;

the outlet of the scrubbing circulation component is connected with the upper part of the filtering tank body through a return pipe, and the filtering tank body is provided with a sewage discharge outlet for discharging backwashing water for cleaning the filtering material to a sludge tank.

Further, the scrubbing circulation component is a special filter material friction cleaning pump.

Furthermore, the filter component adopts walnut shell filter materials.

Furthermore, the lower part of the filtering component is connected with a group of filter screens, and the filter screens are fixed in the filtering tank body.

Furthermore, a water distributor is connected to the water inlet and is used for uniformly spraying the oilfield produced water on the filtering component.

In the technical scheme of the utility model, the produced water in the oil field is input into the filtering component of the filtering tank body, pollutants such as suspended matters and the like in the water are deeply removed, and the treated water is discharged from the water outlet and is reused as the reinjection water in the oil field; after the device equipment operates for a period of time, pollutants such as suspended solids intercepted by the filter assembly tend to be saturated, the filter assembly needs to be cleaned and regenerated, and therefore the filter material is cleaned in an external friction circulation mode by the aid of the cleaning circulation assembly outside the filter material body to clean the internal filter material in an external friction circulation mode, so that scales on the filter material are removed, and the phenomenon that the filter material is hardened can be effectively avoided. The utility model discloses a device cleaning performance is thorough, and the washing water consumption is few, has guaranteed the quality of water of filtration treatment play water, has improved filter material life.
