Abstract
The utility model discloses a swirl type filter used for measuring the collection and the transportation for ground crude oil in an oil field, which is mainly composed of a press cover, a filter casing, a water inlet pipe, a water outlet pipe and a filter screen, wherein a plurality of baffle plates are arranged on one side wall of the filter casing; the water inlet pipe enters the filter in a tangential way; the bottom part of the filter casing is communicated with a pollution discharge device. The utility model can be used for separating and settling impurities in fluids for three times, and the filtering effect is good. Thereby, the service life of a flowmeter is extended, the measuring accuracy for the crude oil is improved and the labor intensity for the pollution discharge and the cleaning in the field is low.
Description
One, technical field
The utility model relates to a kind of spiral-flow type filter, particularly a kind of spiral-flow type filter that is used for the crude oil transmission metering of ground, oil field.
Two, background technology
In the crude oil transmission measurement flow of ground, oil field, generally adopt the metering device of flowmeter, simultaneously as crude output, arrange for preventing oil well that the impurity of greater particle size enters flowmeter in the liquid, filter often was installed before flowmeter,, is reduced error in dipping to reduce the damage probability of flowmeter.At present, because Oilfield using water mixing companion thermal flow process, the incrustation scale that high temperature produces in the production process, and long-time produce the influence that rust deposite that the back oil pipe produces and down-hole go out factors such as sand, the employed single filter significant discomfort in petroleum metering station is answered the produced on-site needs, poor filtration effect, cause problems such as flowmeter damage, error increase thus, reduced the accuracy rate of data admission, cause greater loss to production, and maintenance activity is frequent, and filter cleaning amount is big, and the execute-in-place labor strength is big.
Three, summary of the invention
The purpose of this utility model is at above-mentioned technical problem, develops a kind of novel cyclone type filter, to improve filter effect, reduces error in dipping, alleviates the execute-in-place working strength of workers.
For reaching this purpose, the technical scheme that the utility model is taked is: a kind of spiral-flow type filter, comprise gland, filter housings, water inlet pipe, outlet pipe, filter screen, filter screen is horizontally set on below the outlet pipe, the filter head housings body sidewall is provided with a plurality of baffle plates, baffle plate is between filter screen and water inlet pipe, and water inlet pipe tangentially enters filter, and the filter housings bottom is communicated with blowdown apparatus.
In the technique scheme, the filter housings bottom is an inverted cone-shaped structure, and baffle plate is 2-5, and is the dipping type setting, and its radical length is greater than 1/2nd of the filter housings diameter.
After adopting technique scheme, the utility model has brought beneficial effect: the impurity in the fluid carries out separate and subside three times in filter, improved filter effect, reduce the stifled probability of card of flowmeter, prolonged the service life of flowmeter, reduced error in dipping, the impurity of Fen Liing is deposited in the bottom container of filter simultaneously, regularly open blowdown apparatus and carry out the blowdown flushing, do not need to open again the filter gland and clean, alleviated the execute-in-place working strength of workers.
Four, description of drawings
Fig. 1 is a structural representation of the present utility model.
Five, the specific embodiment
Specify working method of the present utility model below in conjunction with accompanying drawing:
As shown in Figure 1, the utility model comprises gland 1, filter housings 5, water inlet pipe 6, outlet pipe 2, filter screen 3, filter screen 3 is horizontally set on below the outlet pipe 2, filter housings 5 sidewalls are provided with a plurality of baffle plates 4, baffle plate 4 is between filter screen 3 and water inlet pipe 6, water inlet pipe 6 tangentially enters filter, filter housings 5 bottoms are communicated with blowdown apparatus 7, filter housings 5 bottoms are inverted cone-shaped structure, baffle plate 4 is 2-5. and be the dipping type setting, and its radical length is greater than 1/2nd of filter housings 5 diameters.
Operation principle of the present utility model is: fluid tangentially enters filter by water inlet pipe 6 and produces rotation, and the impurity of big particle diameter is because rotation and gravity effect and separate and subside, carries out impurity and the separating of the liquid first time.Owing to filter the effect of baffle plate 4, do not have being kept off back of sedimentation for the first time when liquid rises, under the effect of rotation and gravity, carry out separating the second time than small particle diameter impurity.Behind secondary separation liquid, liquid rises to filter top and filters through filter screen 3, separates for the third time, and fluid enters flowmeter by filter top outlet pipe 2 and measures.
In using at the scene, the utility model is welded on the suction line before the flowmeter, notes low in and high out.Open flowmeter lower part outlet gate during use earlier, open entrance gate again, begin to carry out one-well metering after a few minutes.After one-well metering is intact, import other well gauging successively.Gauging finishes, and opens water mixing washing and filtering device.According to gauging workload size, regularly open the blowdown apparatus blowdown.
