Abstract

The utility model relates to oil field flooding equipment, in particular to a back-flushing-type filtering and cleaning device for oilfield flooding. The back-flushing-type filtering and cleaning device comprises a tank, a water inlet pipeline, a water outlet pipeline and internal filtering components. The filtering components are slotting screen tubes evenly distributed in the tank. Funnel-shaped strainers are arranged in cavities on the upper portions of the slotting screen tubes, and sand setting tubes are movably connected at the lower ends of the slotting screen tubes. A sewage discharge pipeline is arranged at the bottom of the tank. A bypass water back-flushing pipeline or compressed air pipeline is arranged on the water outlet pipeline. The back-flushing-type filtering and cleaning device is simple in structure and convenient to operate, and has the advantages that labor intensity of maintenance can be reduced while filtering efficiency is improved, service life of filtering media is prolonged to some extent, and production cost is reduced as compared with the prior art.

Description

A kind of oil-field flooding backpulsing filters dirt separator
Technical field
The utility model relates to oilfield water injection equipment, is specifically related to a kind of oil-field flooding backpulsing and filters dirt separator.
Background technology
Need to remove the granular impurity in the water at present in the oil-field flooding operation, usually adopt the mode of filter filtration, but the prolongation along with filtration time, phenomenon of blocking often appears in filter medium (or filter core), cause filter efficiency to descend, have to manually open filter and change or clear up, cause the interruption of ordinary production, and a lot of filter volume are huge, and the labour intensity of dismounting is bigger.
The utility model content
The purpose of this utility model is exactly the defective that exists at prior art, provides a kind of oil-field flooding backpulsing simple in structure, easy to operate, that can significantly reduce to safeguard labour intensity and improve filter efficiency to filter dirt separator.
The utility model is achieved through the following technical solutions: comprise the water inlet that connects on tank body and the outer wall thereof and water outlet pipeline, inner filter element, described filter element is uniform fixing cutting seam sieve tube in the tank body, and the inner chamber on cutting seam sieve tube top is provided with the funnel-form filter screen, the bottom flexibly connects sand sediment pipe; Described tank base is provided with blowdown pipeline, and described water outlet pipeline is provided with bypass water recoil pipeline or compressed-air line.During operate as normal, sewage enters filter by back with water inlet line, and through discharging by the water outlet pipeline behind cutting seam sieve tube and the funnel-form strainer filtering, the impurity of funnel-form strainer filtering (such as sand grains) is settled down in the sand sediment pipe, prevent that impurities accumulation is too much, stop up cutting seam sieve tube and funnel-form filter screen; When the medium obstruction in filtering parts, occurring, can close the valve on its back with water inlet line; Then from bypass water recoil pipeline or compressed-air line is oppositely introduced clear water or compressed air enters in the tank body, back flush funnel-form filter screen and cutting seam sieve tube will stop up that filter bores impurity washes and by the discharge of the blowdown pipeline at jar end; Foreign material are assembled too much at the bottom of jar, and are difficult for passing through to recoil when discharging, and can regularly open low head and thoroughly remove; Need in addition regularly sand sediment pipe to be opened cleaning.。
At the requirement of oil-field flooding operation, the seam of described cutting seam sieve tube is wide 2.5 millimeters; For the ease of opening the sand sediment pipe cleaning, the sand sediment pipe design is made up of the plug of body and bottom thereof, opens plug and namely can clear up magazine.
For the ease of device is safeguarded, and make things convenient for the artificial blowdown regularly of tank body, tank body is upper and lower to flexibly connect upper and lower end socket respectively, and wherein upper cover is provided with Pressure gauge and air bleeding valve, Pressure gauge can be monitored the pressure in the filter, and air bleeding valve is used for the exhaust operation before operate as normal begins; Blowdown pipeline is located on the described low head.
The utility model is simple in structure, easy to operate, compared with prior art, reduces the labour intensity of maintenance work when can improve filter efficiency, and has also prolonged the service life of filter to a certain extent, has reduced production cost.
Description of drawings
Fig. 1 is the structural representation of a kind of embodiment of the utility model;
Wherein 1, air bleeding valve, 2, the M24 fastening bolt, 3, the M20 fastening bolt, 4, Pressure gauge, 5, inlet valve, 6, back with water inlet line, 7, the recoil pipeline, 8, recoil valve, 9, Pressure gauge, 10, screen pipe, 11, water outlet pipeline, 12, flowing water Valve, 13, tank body, 14, blowdown pipeline, 15, sewage draining valve, 16, the annular brace mouth, 17, funnel-form filter screen, 18, cutting seam sieve tube, 19, sand sediment pipe.
The specific embodiment
With reference to Fig. 1, be that the oil-field flooding backpulsing filter that designs at oilfield sewage water mixing production is that example is described further the utility model below, tank body 13 comprises cylindrical shell and the upper and lower end socket that connects by M24 fastening bolt 2, and the junction is provided with the high strength sealing ring; Uniform many group screen pipes 10 in the cylindrical shell, the middle and lower part of every screen pipe 10 is the cutting seam sieve tube structure, is evenly equipped with on cutting seam sieve tube 18 tube walls that seam is wide 2.5 millimeters, spacing is the seam of 5cm; The screen pipe inner chamber on cutting seam sieve tube 18 tops is provided with funnel-form filter screen 17, the bottom flexibly connects sand sediment pipe 19, and sand sediment pipe 19 designs are made up of the plug of body and bottom thereof; Many group screen pipe 10 peripheries are fixed on the annular brace mouth 16 on the cylinder inboard wall by M20 fastening bolt 3, and the junction is provided with the high strength sealing ring.Upper cover is provided with air bleeding valve 1 and Pressure gauge 9, and the cylindrical shell downside is provided with back with water inlet line 6, upside is provided with water outlet pipeline 11, and low head is provided with blowdown pipeline 14; Be provided with inlet valve 5 and Pressure gauge 4 on the back with water inlet line 6 successively, be provided with Pressure gauge 4 and flowing water Valve 12 on the water outlet pipeline 11 successively, blowdown pipeline 14 is provided with sewage draining valve 15; Connect bypass water recoil pipeline 7(or compressed-air line on the water outlet pipeline 11), which is provided with recoil valve 8.The fastening bolt of whole filter all adopts high-strength bolt, and the withstand voltage in the assurance work is more than 4.8Mpa.
It below only is an exemplary embodiments of the present utility model, those skilled in the art can carry out rational conversion to the structure of above-described embodiment fully according to operation occasion, job requirements etc., with filtration and the flushing operation that is applicable to various fluids (liquid or gas), just do not enumerate one by one at this.
