Embodiment 1
[0044] like Figure 1 to Figure 7 As mentioned above, this embodiment discloses an oil recovery filtration device, which includes a main tank body 1, specifically: the bottom of the main tank body 1 is provided with an air-water mixer 2, and the air-water mixer 2 includes a hollow box with an upper opening 7 and a net cover 8 covering the opening of the box body 7, a horizontally rotatable vane wheel 6 is provided in the cavity of the box body 7, the side of the box body 7 is connected to the sewage pipe 3, and the bottom surface of the box body 7 is connected to the air intake pipe 4 The top of the air-water mixer 2 is provided with a conical primary filter 9, and the peripheral edge of the conical primary filter 9 is connected with the inner wall of the main tank body 1; the top of the conical primary filter 9 is provided with an overflow settler 10, and the overflow The inside of the settler 10 is provided with a conveying device and the lower end of the overflow settler 10...
Embodiment 2
[0062] Embodiment 1 describes and illustrates the filtering equipment structurally. This embodiment discloses a method for oil production filtration using the equipment in Embodiment 1, which mainly includes the following steps:
[0063] S001: Add flocculants, coagulants and bactericides to the oily sewage to be filtered, and then inject oily sewage into the air-water mixer 2 through the water inlet pipe; at the same time, inject compressed gas into the air-water mixer 2 through the air inlet pipe 4 ;
[0064] S002: The gas-water mixture overflowing from the gas-water mixer 2 is prefiltered by the conical primary filter 9, enters the space above the conical primary filter 9, and begins to flocculate and form a suspension layer. The suspended layer intercepts, and the continuously thickened suspended layer enters the overflow barrel 1001 and reaches the bottom of the overflow barrel 1001;
[0065] S003: start the hydraulic motor and drive the auger to run, and the auger transp...
