Abstract
The utility model relates to oilfield water injection equipment, in particular to an oilfield water injection back-flushing type filtration dirt separator. The dirt separator comprises a tank body, a water inflow pipeline and a water outflow pipeline which are connected to the outer wall of the tank body and filtering parts inside the tank body, wherein the filtering parts are filter pipes which are uniformly distributed and fixed in the tank body; the upper ends of the walls of the pipes are provided with openings, and the lower ends of the walls of the pipes are sealed; a plurality of filter holes are uniformly distributed on the outer walls of the pipes; a dirt discharging pipeline is arranged at the bottom of the tank body; and a bypass back-flushing pipeline is arranged on the water inflow pipeline. The dirt separator has a simple structure and is convenient to operate; and compared with the prior art, the dirt separator has the advantages that the labor intensity of maintenance operation can be reduced while the filtering efficiency is improved, the service life of a filter is prolonged to a certain extent, and the production cost is reduced.
Description
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 in the oil-field flooding operation at present to remove the granular impurity in the water, the mode that adopts filter to filter usually, but along with the prolongation of filtration time; Phenomenon of blocking often appears in filter medium (or filter core); Cause filter efficiency to descend, the manual work of having to is opened filter and is changed or clear up, and causes 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 the utility model is exactly the defective that exists to 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 realized through following technical scheme: comprise the water inlet that connects on tank body and the outer wall thereof and water outlet pipeline, inner filter element; Wherein filter element is to be uniformly distributed with fixing screen pipe in the tank body, and tube wall open upper end, lower end closed, outer wall are uniformly distributed with a plurality of filtering holes; Tank base is provided with blowdown pipeline, and back with water inlet line is provided with bypass recoil pipeline.During operate as normal, sewage gets into filter through back with water inlet line, filters the back through the filtering holes on the screen pipe and discharges through the water outlet pipeline; When occurring the medium obstruction in the filter, can close the valve on its back with water inlet line; Oppositely introduce clear water from the water outlet pipeline then and get in the tank body, the back flush screen pipe will stop up the bypass recoil pipeline that filtering holes impurity washes and pass through on the back with water inlet line and discharge; Foreign material are assembled too much at the bottom of jar, and when being difficult for discharging through the recoil pipeline, can regularly opening blowdown pipeline and thoroughly remove.
To the requirement of oil-field flooding operation, the filtering holes diameter is designed to 2 millimeters, and the filtering holes spacing is 7 millimeters, the best results of filtration.In order to improve filter effect, and the wearing and tearing that reduce filtering holes, screen pipe is wrapped with screen pack.The filter tank body is provided with Pressure gauge and air bleeding valve, and Pressure gauge can be monitored the pressure in the filter, and air bleeding valve is used for operate as normal and begins preceding exhaust operation.
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.

Fig. 1 is the structural representation of a kind of embodiment of the utility model;
Fig. 2 is the cutaway view of A-A among Fig. 1;
Fig. 3 is a B portion enlarged drawing among Fig. 1;
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 valve, 8, the recoil pipeline; 9, Pressure gauge, 10, screen pipe, 11, the water outlet pipeline, 12, flowing water Valve; 13, tank body, 14, blowdown pipeline, 15, sewage draining valve, 16, the annular brace mouth.
The specific embodiment
With reference to Fig. 1-3; Be that the oil-field flooding backpulsing filter that designs to oilfield sewage water mixing production is that example is done further explanation to the utility model below; Tank body 13 comprises cylindrical shell and the cover that connects through M24 fastening bolt 2, and the junction is provided with the high strength sealing ring; Be uniformly distributed with many groups in the cylindrical shell and filter tube bank 10, be evenly equipped with diameter on every screen pipe tube wall and be 2 millimeters filtering holes, its spacing is 7 millimeters, and filtering holes is wrapped with screen pack; Many groups are filtered tube bank 10 peripheries and are fixed on the annular brace mouth 16 on the cylinder inboard wall through M20 fastening bolt 3, and the junction is provided with the high strength sealing ring.Cover is provided with air bleeding valve 1 and Pressure gauge 9, and the cylindrical shell downside is provided with that back with water inlet line 6, upside are provided with water outlet pipeline 11, the bottom 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 recoil pipeline 8 on the back with water inlet line 6, which is provided with recoil valve 7.The fastening bolt of whole filter all adopts high-strength bolt, and the withstand voltage in the assurance work is more than 4.8Mpa.
Be elaborated in the face of its specific operation process down:
1, filter element exhaust
Open inlet valve 5 water inlet,, slowly open air bleeding valve 1 gas slowly in the tank body is emitted,, close air bleeding valve 1, accomplish exhaust process until there being the water continous-stable to flow out to the stable reading of water inlet pipe and water outlet pipe linear pressure table 4 and when consistent.
2, normal filtration operation
Open Inlet and outlet water valve 5 and 12; Sewage is got in the tank body 13 by back with water inlet line 6; Get into screen pipe 10 through screen pack, filtering holes; Discharge through water outlet pipeline 11 then, can regulate the pressure and the flow of water outlet in the running, so that satisfy of the requirement of road water mixing pumping system in back for flow and pressure.
3, backwashing procedures
When the pressure that filters the unit falls (pressure differential of filter Inlet and outlet water) when exceeding setting value, can carry out backsurging operation, to reach the purpose that reduces filtration resistance.Specific operation process is following: closes inlet valve 5, opens recoil valve 7, and behind water outlet pipeline 11 introducing clear water entering screen pipes 10, back flush filtering holes and screen pack, recoil water is through recoil pipeline 8 discharge filters; When range estimation recoil water is comparatively clean, promptly accomplish a backwash operation.
It below only is an exemplary embodiments of the utility model; Those skilled in the art can carry out rational conversion to the structure of the foregoing description 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.
