Petrochemical industrial wastewater desalination treatment device

The utility model relates to the technical field of industrial wastewater desalination, in particular to a petrochemical industrial wastewater desalination treatment device which comprises a water outlet pipe, one end of the water outlet pipe is movably connected with a heating bin, the other end of the water outlet pipe is movably connected with an evaporator, and one side of the heating bin is movably connected with a water inlet pipe. According to the improved desalination treatment device, the water pipe is wound between the heating blocks, so that wastewater is fully heated and pretreated, and the wastewater is atomized upwards, so that the wastewater has a larger heating area and longer heating time; the water cooler is fixedly connected to the side close to the water conveying pipe, so that all cooled and liquefied wastewater flows into the water conveying pipe and is prevented from flowing back to the evaporator, a clamping groove is formed in the top of the ultrafiltration bin, an ultrafiltration mem
