The utility model relates to a flowing back efficient handling of device is returned to fracturing, including elevator pump I, chemicals tank, reactor, solid -liquid separation ware, gravitation filter, elevator pump I be connected with the reactor through the pipeline respectively with chemicals tank, the entry of export and solid -liquid separation ware of reactor pass through the screw pump and be connected, the entry of liquid outlet and gravitation filter of solid -liquid separation ware pass through elevator pump II and be connected, the bottom of solid -liquid separation ware be equipped with the drain. Simple structure, application scope is wide, can high -efficient realization oil field oil, the gas well fracturing returns flocculating settling, the solid -liquid separation of flowing back and filter the clarification, can satisfy the on -the -spot fracturing reuse in oil field, discharge to reach standard, recycle stratum mesh to reduce and to dig the mud pit operation, save the soil, the flowing back efficient handling of device is returned to fracturing of environmental protection.
