Efficient high-temperature oily wastewater ion exchange softening treatment device

The utility model relates to an efficient high-temperature oily wastewater ion exchange softening treatment device. The efficient high-temperature oily wastewater ion exchange softening treatment device comprises a raw water injection system (101), an ion exchange system (201) containing an ion exchange column (211), a softened water collection system (301), an acid-base regeneration system (401) and a waste liquid recovery system (501) as well as a regeneration forward-flow switching pipeline (601), an ion exchange column middle liquid inlet pipeline (701) and an ion exchange column middle regenerated liquid inlet pipeline (711). By adopting the device, conventional washing and backwashing processes, forward-flow and counterflow acid-base liquid regeneration processes and brine regeneration processes can be performed; in the conventional washing and backwashing and regeneration processes, the liquid can enter the column body from the top, bottom or middle part of the ion exchange column (211). The efficient high-temperature oily wastewater ion exchange softening treatment device has the advantages that the structure is simple, the operation is flexible, high-temperature resistance and acid-base corrosion resistance are achieved, liquid can be rapidly discharged, the conventional washing and backwashing and regeneration processes can be rapidly and efficiently performed, the scaling of boiler pipelines is effectively prevented and thus the accident of pipe explosion is avoided.
