The utility model is mainly composed of a coarse filtering tank, a fine filtering tank, a hot cleaning device for deoiling filtering materials, a regenerating and back washing impeller device for filtering materials, a regenerating and back washing pump cleaning device for filtering materials and filtering materials. The utility model has large flow quantity and high filtering precision, is widely used for filtering the water quality of the water injected into the oil wells and can be used as a prestage processing device of a high purity water processor in textile industry, chemical industry and electronic industry. After treatment, the turbidity degree of the effluent water is equal to and smaller than 2.5 mg/L, and the granularity is equal to and smaller than 5 mu metres. The utility model uses a positive filtering mode or a reverse filtering mode, has the advantages of reasonable structure, convenient operation, high precision and large flow quantity and is an ideal apparatus for filtering the water quality of the water injected into the oil wells.
Description
The utility model relates to a kind of improved oil-field flooding water filter, particularly a kind of big flow, high filtering precision, the strainer of energy backwash.Be suitable for the filtration of water injection well in oil fields working fluid, also can be used as weaving, chemical industry, electron trade high purity water processor prestage treating apparatus.
At present, some flourishing oil-producing countries are in order further to improve the output of low-permeability oil deposit in the world, having used through precision is 2 μ m(absolute values) working fluid that filters of strainer, the result has delayed the stratum damage greatly, water injection pressure and in-place permeability have been stablized, reduce the well workover number of times of water injection well in oil fields, increased oil well output.So, the filtering technique of working fluid from middle nineteen seventies along with being developed.Existing technology mainly contains following two kinds:
A kind of is the working fluid strainer that the development of U.S. Silver Band company is used, and mainly is made up of institutes such as coarse filtration jar, the smart filter cylinder of wound form, media regeneration device, water-supply-pipe, valves.Its shortcoming is that flow velocity can not be too big, and service condition is required can be severe, and smart filter core can not be regenerated, thus the trouble of use, cost up.
Another kind is the rapid filter of Japanese Long Niqika company development, though filtering velocity is higher, it is to become the filter core of mop shape to add shell by a kind of 10 μ m polypropylene silk fiber bundles that curl to assemble, make trouble, use also inconvenient.
Task of the present invention is that a kind of improved working fluid strainer will be provided, it can be at high speed with the water filtration of injecting the down-hole to below the 5 μ m (absolute value), reality can reach about 1 μ m, to satisfy oil-field flooding water filtration requirement.
Task of the present invention is finished as follows: on the metab of a skid-mounted type, polyphone is installed strainer coarse filtration jar, smart filter tank side by side, simultaneously, the mechanical backwash impeller unit or the blower fan swirl washing device of media regeneration are installed on the filtering tank, then, according to selection, in the filtering tank of filtrate can being packed into, filtrate in coarse filtration jar and the smart filter tank is respectively walnut shell and fibrous nodules is used in combination, and also can be used in combination for dress fibrous nodules in dress fibrous nodules and the smart filter tank in the coarse filtration jar.What the present invention adopted is that walnut shell is that coarse media and fibrous nodules are the mode that is used in combination of smart filtrate.In order to regulate inflow, the present invention also is equipped with diaphragm valve in the aqueduct of strainer simultaneously.The present invention is in order to solve the regeneration of coarse media in addition, on the coarse filtration jar design and installation backwashing pump cleaning device.To the specific (special) requirements of metal product corrosion and reduce cost, save steel according to oilfield sewage, the inner surface hot spraying at filtering tank has aluminium paint again.Also have in conjunction with characteristics of the present invention, designed and filtered dual mode forward or backwards, can be for adopting.In order to solve the oil removing problem that oilfield sewage filters filtrate in the re-injection, the present invention also on filtering tank design and installation the hot cleaning device of oil removing is arranged.So the present invention mainly is made up of water-supply-pipe, control valve of water pump, coarse filtration jar, smart filter tank, media regeneration backwash device, oil removing hot washing device, filtrate.It is rational in infrastructure, and is easy to operate, is the ideal equipment of oil-field flooding water filtration.
