Detailed Description

The utility model will now be described in detail, by way of example, with reference to the accompanying drawings, wherein it is evident that the embodiments described are only some, but not all, of the embodiments of the utility model.

As shown in fig. 1, the utility model provides an oil-gas-water separation device, which comprises a tank body 1, wherein the tank body 1 adopts a horizontal structure, and one side of the tank body is provided with a manhole 16, so that the internal condition of the tank body 1 can be conveniently observed; the top of the tank body 1 is provided with a feed inlet 2 and an exhaust outlet 3, an anti-overflow baffle 13 is arranged below the feed inlet 2, the anti-overflow baffle 13 is fixedly connected to the inner top wall of the tank body 1, and the anti-overflow baffle 13 blocks the flow direction of the mixed liquid so as to avoid affecting the floating of the gas in the sedimentation cavity 7; the mist catcher 15 is arranged on the exhaust port 3, and the mist catcher 15 can separate fine water drops entrained in the gas, so that the fine water drops are condensed into larger water drops to be deposited.

Further, in this embodiment, a separation weir plate 4 is provided inside the tank 1, and a plurality of through holes 5 are provided on the separation weir plate 4. Specifically, the separation weir plate 14 is formed by splicing a horizontal section and an inclined section, and the diameter of a through hole on the horizontal section is smaller than that of a through hole on the inclined section; the separation weir plate 4 separates the inner cavity of the tank body 1 into a separation cavity 6 on the upper layer and a sedimentation cavity 7 on the lower layer, the feed inlet 2 and the exhaust port 3 are both communicated with the separation cavity 6, the separation cavity 6 is communicated with the sedimentation cavity 7 through a plurality of through holes 5, an overflow plate 8 is arranged in the sedimentation cavity 7, the overflow plate 8 is of an L-shaped structure, the sedimentation cavity 7 is separated into a water collecting chamber 9 and a water collecting chamber 10 by the overflow plate 8, a water outlet 11 and a sewage drain 14 are arranged at the bottom of the water collecting chamber 9, and an oil drain port 12 is arranged on one side of the water collecting chamber 10.
