  • Publication number: 20240123372
    Abstract: A process for treating aged oil by electron beam irradiation is disclosed, comprising the following steps: step 1, homogenizing the aged oil and then feeding the aged oil into a distributor; step 2, forming a liquid layer having a certain thickness on the distributor; step 3, installing and debugging an electron beam irradiation device on the distributor; step 4, installing and debugging a phased-array microwave emitter on the distributor after installing and debugging the electron beam irradiation device; step 5, turning on the electron beam irradiation device and the phased-array microwave emitter; and step 6, dividing the treated aged oil and then allowing the aged oil after dividing to enter an oil pool and a water pool for standing. Oil flows out from an upper layer of the oil pool, a lower layer of the oil pool flows back to an aged oil storage pool.

  • Patent number: 11383996
    Abstract: The present invention discloses an oil-contained wastewater treatment apparatus applying the integrative physical methods. The wastewater treatment system of the invention may include a main tank, where the upper part is a rectangular body and the lower part is designed to a multi-bucket bottom structure. Two oil collection boxes are arranged to both outside ends of tank. A mud discharging outlet is attached to the bottom of the tank. Meanwhile, both of a water outlet and an electric polarizer are localized at the end face of the effluent on the tank. A power supply for the electro-adsorber is fixed to the inlet end on the top face of the tank. Divided by upper and lower deflectors, the inside of the tank is divided to three processing units, i.e., sludge-water separation unit, degradation-coalescence treatment unit, and sedimentation-electric polarization unit. Vortex centripetal gas flotation is applied to remove oil. Electro-adsorption induces the micelle clustering to achieve the decolorization.
