Abstract
The utility model relates to an oily sewage backwashing and filtering device and belongs to separation devices. The device comprises a filter bed arranged in a filter, wherein a screen pipe fixed with the filter is arranged at the upper part of the filter bed; a filtering water inlet pipe (a) and a backwashing water drainage pipe (b) are arranged on the pipe wall of the filter and at the upper part of the screen pipe; a filtering water outlet pipe (c) and a backwashing water inlet pipe (d) are arranged at the bottom of the filter; an exhaust pipe (e) and a drainage pipe (f) are arranged at the top of the filter; and an overflow pipe (g) is arranged at the upper part of the filtering water inlet pipe (a) and the backwashing water drainage pipe (b). The utility model has the advantages of compact structure, small volume, high efficiency, simple and convenient operation, and stable and reliable work; the stainless steel screen pipe is additionally installed in a water inlet system, so as to prevent fine filter materials from being discharged in the backwashing process; the device adopting materials with great density, strong rigidity and smooth surface can realize clean and thorough backwashing and effectively remove floating substances and oil from water; and the backwashing is more thorough, thereby greatly improving the water discharge standard.
Description
Technical field
The utility model belongs to tripping device, particularly relates to a kind of oily(waste)water backwash filtration unit.
Background technology
At present, the most of exploitation well in domestic oil field all adopts the waterflooding mode, promptly injects high pressure water driving crude oil it is come out from the oil well exploitation.Along with the prolongation of development time, the extraction crude oil water content constantly rises, and water must be sloughed before and crude oil is defeated outside, therefore can produce a large amount of oily(waste)waters.Because oilfield sewage is because the salinity height, sour gas such as hydrogen sulfide in various degree, carbonic acid gas have been dissolved again, the stratum is injected in such sewage recycling can produce corrosion to treatment facility, waterflood system, therefore the back re-injection is all handled sewage in each oil field, reduce wastewater disposition to greatest extent on the one hand, reduce the purpose of polluting thereby reach the protection environment; The construction cost of a large amount of clear water resources and replacement facility can also be saved on the other hand, and the whole economic efficiency of water flooding can be improved.But existing oil-field water treatment facility is in anti-cleaning process, and a lot of tiny filtrates often are pulled away, and cause the waste of filtrate.
Summary of the invention
The utility model is intended to overcome the deficiencies in the prior art, and a kind of oily(waste)water backwash filtration unit is provided.
Oily(waste)water backwash filtration unit of the present utility model, be in strainer, to be provided with filter bed to constitute, be provided with screen casing on the top of filter bed and strainer fixes, on the tube wall of strainer, the top of screen casing is provided with filtered water inlet pipe a and backwash water shoot b, be provided with in the bottom of strainer and filter out water pipe c and backwash water inlet pipe d; Be provided with vapor pipe e and blow-off pipe f at the top of strainer.
As further improvement of the utility model, be to be provided with upflow tube g on the top of filtered water inlet pipe a and backwash water shoot b.
The utility model oily(waste)water backwash filtration unit, compact construction, volume is little, efficient is high, easy and simple to handle, working stability is reliable; Installed the stainless steel screen casing additional at water inlet system, prevented from backwash process, tiny filtrate to be taken away; The density of material that this device adopts is big, hardness strong, smooth surface, and back flushing is totally thorough, can effectively remove suspended substance and oil in the water, because backwash is more thorough, effluent index improves greatly.
Description of drawings
Figure of description is the structural representation of the utility model oily(waste)water backwash filtration unit.
Embodiment
The utility model oily(waste)water backwash filtration unit, be in strainer 1, to be provided with filter bed 2 to constitute, it is characterized in that being provided with screen casing 3 on the top of filter bed 2 fixes with strainer 1, on the tube wall of strainer 1, the top of screen casing 3 is provided with filtered water inlet pipe a and backwash water shoot b, be provided with in the bottom of strainer 1 and filter out water pipe c and backwash water inlet pipe d; Be provided with vapor pipe e and blow-off pipe f at the top of strainer 1.This device installs the energy dissipating plate structure additional in strainer, filtrate stops up the problem of screen casing when greatly reducing backwash.
Top at filtered water inlet pipe a and backwash water shoot b is provided with upflow tube g.
