Embodiment 1

[0047] A device for sewage filtration provided in this embodiment, such as figure 1 As shown, it includes a tank body 10 , a pump body 80 , a controller 60 , and a driving device 70 for driving the primary filtration device 40 to rotate. The primary filtration group includes three primary filtration devices 40 arranged at intervals in the tank body 10 , namely a first primary filtration device 40a, a second primary filtration device 40b and a third primary filtration device 40c. refer to figure 2 As shown, the primary filtration device 40 is provided with flow channels 41 communicating with both sides.

[0048] The tank body 10 is provided with a steady flow device 20, a rectification device 30, a primary filtration group and an oil gathering device 50 in sequence along the direction of water flow; the tank body 10 is provided with a medium inlet 11 at the sewage inlet end, and a Drain 13. A sludge outlet 12 is provided at the bottom of the tank body 10 , at least between ...

Embodiment 2

[0060] This embodiment is basically the same as Embodiment 1, the difference is:

[0061] Such as Figure 4 As shown, the primary filtration device 40 includes: a mounting frame 43 and a plurality of primary filtering corrugated plates 44; the primary filtering corrugated plates 44 can be horizontally slidably arranged on the mounting frame 43 in a direction perpendicular to the water flow direction Y; Specifically, the top and the bottom of the installation frame 43 are provided with slide grooves perpendicular to the water flow direction Y, and the upper and lower ends of the primary filtering corrugated plate 44 are slidably inserted into the slide grooves. An end spring 45 is arranged between the installation frame 43 and the primary filter corrugated plates 44 on the front and rear sides, and a spacer spring 46 is arranged between two adjacent primary filter corrugated plates 44, and two adjacent primary filter corrugated plates 44 are provided with spacer springs 46. Th...

Abstract

The invention provides a sewage filtering device, which relates to the technical field of oil-water separation, and comprises a tank body, a pump body, a controller and a driving device, a primary filtering group and an oil gathering device are arranged in the tank body; a primary filtering device is pivoted in the tank body, and the driving device is used for driving the primary filtering deviceto rotate and adjusting the included angle between a flow channel and the horizontal direction; the controller is connected with a first sensor, a second sensor, a pump body and a driving device. Thecontroller adjusts the flow speed and flow of sewage through the pump body according to detection results fed back by the first sensor and the second sensor, controls the inclination angle of the flowchannel of the primary filtering device through the driving device, and adjusts the filtering coalescence oil removal speed of the sewage. The sewage treatment device is high in automation degree, can automatically adjust the filtering coalescence oil removal speed of sewage according to the water quality conditions before and after sewage treatment, and improves the sewage treatment speed as much as possible under the condition that the final excellent treatment effect is guaranteed.

Description

technical field [0001] The invention relates to the technical field of oil-water separation, in particular to a device for filtering sewage. Background technique [0002] At present, most domestic old oilfields have entered the development period of ultra-high water cut. With the adoption of development techniques such as water flooding, polymer flooding, ASP flooding, heavy oil recovery, and gas flooding, the produced water in oilfields has various water types and complex water properties. Corrosive characteristics. [0003] Traditional oil-water separation treatment equipment is basically made of metal materials, with poor corrosion resistance and serious corrosion, especially for small pressure separation equipment (three-phase separator, coalescing degreaser, filter) due to its small internal space and The components are complex, and the traditional anti-corrosion methods cannot be effectively implemented. Up to now, no effective way to control corrosion has been found....
