Brief description of the drawings
Fig. 1 is the structure diagram of the utility model.
Embodiment
The utility model is described in detail below in conjunction with attached drawing, not limits the scope of protection of the utility model, it is all to use this practicality
The improvement that new mentality of designing is drawn belongs to the protection category of the utility model.
Referring to Fig. 1, filtration apparatus early period of oil field recharged waste water includes outer barrel 3 and screen pipe 5, outer barrel 3 be equipped with sewage into
Mouth 1 and outfall 9, outer barrel 3 is interior to be equipped with support plate 4 and header tank 7 with flowing hole 6, the axis of screen pipe 5 and outer barrel 3
Line is parallel, is erected between support plate 4 and header tank 7, filteringPipe5 end is connected with header tank 7, and header tank 7 passes through water purification
Discharge pipe 8 is connected with ultrafiltration technology process flow.
The header tank 7 is that cylindrical box, the width of its cylindrical overcurrent annular space between outer barrel 3 are set in 8cm-
Between 20cm.
The width of overcurrent annular space is set between 12cm-16cm between the header tank 7 and outer barrel 3, this is preferred ruler
It is very little, not only allowed oily wastewater quickly to be flowed in the annular clearance of the two, but also chock pressure difference can be formed and force sewage from screen pipe 5
Flow through carry out permeation filtration.
The aperture of the wastewater inlet 1 of the outer barrel 3 is more than the aperture of outfall 9, the barrel front end and end cap of outer barrel 3
2 are threadedly coupled, and wastewater inlet 1 is located in end cap 2,2 convenient disassembly of end cap, easy access and replacement screen pipe 5.
Screen pipe 5 in the outer barrel 3 at least sets three, the front end closing of screen pipe 5, rear end path insertion header tank
In 7, screen pipe 5 is manufactured using selective permeable material.
Support plate 4 in the outer barrel 3 is with big plectane, equipped with screen pipe mounting hole and flowing hole with 3 inner circle of outer barrel
6, flowing hole 6 is distributed in the plate body outside screen pipe mounting hole.
The wastewater inlet 1, outfall 9 and water purification discharge pipe 8 are sealed with outer barrel 3, the miner diameter end of screen pipe 5 with
Header tank 7 seals.Each component of remaining of this filtration apparatus in addition to screen pipe 5 can select metal or it is nonmetallic manufacture, also may be used
Manufactured with selecting metal material to be combined with nonmetallic materials, but the joint of each component must keep sealing.
Described filtration apparatus can be used in series for more than two, and when being used in series, the water purification of above filtration apparatus is arranged
Outlet pipe 8 is connected with ultrafiltration technology process flow, is connected outfall 9 with the wastewater inlet 1 of following filter device.
When handling oily wastewater using the present apparatus, oily wastewater first passes through wastewater inlet 1 and enters in outer barrel 3, passes through support
Flowing hole 6 on plate 4 flows, and along Cheng Liujing screen pipes 5, in oily wastewater and 5 contact process of screen pipe, water can mutually pass through
The tube wall of chimney filter 5 enters the internal cavity of screen pipe 5, and oil phase is then blocked on the outside of screen pipe 5 and continues to flow with remaining sewage
Until by outside 9 discharger of outfall, the water purification into 5 cavity of screen pipe is collected to inside header tank 7, passes through water purification
Outside 8 discharger of discharge pipe, into ultrafiltration technology process flow, injection water quality requirement is finally reached.Due to whole filtered
Oily wastewater remains flow regime in journey, and the continuous erosion of sewage is subject to by the oil phase that screen pipe 5 obstructs outside, it is difficult to
The surface of screen pipe 5 is attached to, will not form oil film reduces the selective penetrated property of screen pipe 5, therefore the device is with stronger
