A power plant oily wastewater filtration device

Abstract

This application discloses a filtration device for oily wastewater from power plants, belonging to the field of power plant wastewater treatment technology. It mainly includes: a mixing tank, with a discharge component fixedly installed at the lower middle of the mixing tank. A filter component is threadedly connected to the lower end of the discharge component. A connecting pipe is threadedly connected to the lower end of the inner cavity of a through-pipe. When the oily wastewater in the mixing tank is emulsified and discharged, the wastewater and the mixed flocs carried in it will enter the inner cavity of the through-pipe through the connecting pipe. There, they are sequentially filtered and intercepted by a first filter screen and a second filter screen installed within the inner cavity of the through-pipe, thus directly filtering the mixed flocs. When too much mixed flocs accumulate at the upper ends of the first and second filter screens, the connecting pipe is disassembled, and the through-pipe is detached from the threaded connection at the upper end of the connecting pipe. Then, a pull rod is directly pulled to cause the circular retaining ring on the outer wall of the first filter screen to disengage from the circular retaining groove, thereby completing the disassembly and cleaning of the screening mechanism.
