Description

Technical Field

[0001] The utility model relates to the technical field of sewage purification, and more specifically to an integrated produced liquid treatment and sewage purification on-site reinjection skid device. Background Art

[0002] The water content of oilfield production fluid increases year by year, resulting in a rapid increase in the amount of oil production wastewater treatment. After the oilfield production fluid passes through the three-phase separator, a large amount of wastewater is generated. If it is discharged arbitrarily, it will inevitably bring serious consequences. Not only will it waste water and crude oil, but it will also seriously pollute the environment and affect the safe production of the oilfield.

[0003] There is a cyclone channel inside the cyclone, which makes the produced fluid form a rotating flow through the tangential inlet, and uses centrifugal force to achieve the initial separation of oil, water and impurities.

A positioning mechanism and an auxiliary limiting mechanism are arranged between the first base and the second base. The liquid outlet of the oil-water cyclone is connected to the liquid inlet of the TG ceramic precision tubular filter, the air outlet of the air compressor is connected to the air inlet of the air storage tank, and the air outlet of the air storage tank is connected to the air inlet of the TG ceramic precision tubular filter; the technical scheme uses a first base and a second base that can be quickly positioned and assembled. The oil-water cyclone and the TG ceramic precision tubular filter are respectively arranged on the first base and the second base, which can be easily disassembled and transported during transportation. After being transported to the destination, they can be quickly assembled and the various equipment can be connected through pipelines, which greatly facilitates the reinjection water treatment of various oil field production areas.
