Description
Technical Field
The utility model belongs to the field of two-phase flow metering, and particularly relates to a gas-liquid two-phase flow metering device.
Background
In the exploitation process of natural gas such as shale gas, gas-liquid two-phase flow occurs. After mining, two-phase flow needs to be measured, and the measurement by using the two-phase flow meter is a mode for saving mining and measuring cost, reducing land utilization and saving labor cost. However, in the process of metering by using the two-phase flowmeter, the installation position of the two-phase flowmeter may be deviated due to the limitation of the installation space. This may affect the stability of the flow state of the two-phase flow, resulting in inaccurate metering, and thus affect the metering accuracy of the two-phase flow meter.

In one embodiment, a filter screen is arranged at one end of the interior of the fluid rectification filter, which is close to the fluid inlet of the fluid rectification filter.
In one embodiment, the inner diameters of the inlet pipeline, the climbing pipeline, the rectifier connecting pipeline, the front straight pipe section of the flowmeter, the rear straight pipe section of the flowmeter and the outlet pipeline are all consistent.
In one embodiment, arc-shaped transition pipelines are arranged between the inlet pipeline and the climbing pipeline, between the climbing pipeline and the rectifier connecting pipeline and between the rear straight pipe section of the flowmeter and the outlet pipeline.

In the figure: 1. an inlet line; 2. climbing pipelines; 3. a fluid rectifier filter; 4. a flow meter front straight tube section; 5. a gas-liquid two-phase flow meter; 6. a rear straight pipe section of the flowmeter; 7. an outlet line; 8. a rectifier connection line; 9. an arc-shaped transition pipeline.
Detailed Description
The utility model will be described in further detail with reference to the following drawings and specific embodiments.
Example 1:
as shown in figure 1, the gas-liquid two-phase flow metering device comprises a horizontally arranged inlet pipeline 1, a horizontally arranged outlet pipeline 7, a horizontally arranged fluid rectifying filter 3 and a vertically arranged gas-liquid two-phase flow meter 5, the fluid rectifying filter 3 is arranged above the inlet pipeline 1 and the outlet pipeline 7, the inlet pipeline 1 is communicated with the fluid inlet of the fluid rectifying filter 3 through a climbing pipeline 2 which is vertically arranged and a rectifier connecting pipeline 8 which is horizontally arranged in turn, the fluid outlet of the fluid rectifying filter 3 is communicated with the fluid inlet of a gas-liquid two-phase flowmeter 5 through a flowmeter front straight pipe section 4, the fluid outlet of the gas-liquid two-phase flowmeter 5 is communicated with an outlet pipeline 7 through a vertically arranged flowmeter rear straight pipe section 6, the inner diameter of the fluid rectifying filter 3 is larger than the inner diameters of the climbing pipeline 2 and the front straight pipe section 4 of the flowmeter.
The metering device solves the problem that a front straight pipe section and a rear straight pipe section are required to be installed in the actual use process of the two-phase flow meter but the installation space is insufficient through the arrangement mode of each pipeline, and provides conditions for the sufficient mixing of two-phase flow fluid to a certain extent. Moreover, the two-phase flow can be effectively rectified by the arranged fluid rectifying filter 3, and meanwhile, the inner diameter of the fluid rectifying filter 3 is larger than that of the climbing pipeline 2 and the straight pipe section 4 in front of the flowmeter; when the two-phase flow fluid flows through, the pipe diameter is instantly enlarged, the two-phase flow fluid can be fully mixed in the fluid rectification filter 3 and form a stable flow state, and therefore the metering accuracy is guaranteed.
Example 2:
as shown in fig. 1, on the basis of the above embodiment, a filter net is arranged at one end of the interior of the fluid rectifying filter 3 close to the fluid inlet.
The arrangement of the filter screen can filter impurities such as silt possibly contained in the two-phase flow fluid, and can effectively reduce the risk that the gas-liquid two-phase flow meter 5 is washed and blocked by foreign matters.
Example 3:
as shown in fig. 1, on the basis of the above embodiment, the inner diameters of the inlet pipeline 1, the climbing pipeline 2, the rectifier connecting pipeline 8, the meter front straight pipe section 4, the meter rear straight pipe section 6 and the outlet pipeline 7 are all consistent.
The inner diameters of all pipelines are consistent, smooth passing of two-phase flow fluid can be guaranteed, and the mixing effect of the two-phase flow fluid cannot be influenced due to frequent change of the pipe diameter.
Example 4:
as shown in fig. 1, in addition to the above embodiment, arc-shaped transition pipelines 9 are respectively arranged between the inlet pipeline 1 and the climbing pipeline 2, between the climbing pipeline 2 and the rectifier connecting pipeline 8, and between the rear straight pipe section 6 of the flowmeter and the outlet pipeline 7.
The arc transition pipeline 9 can ensure the stable transition of the two-phase flow fluid and ensure the smooth operation of the two-phase flow fluid.
When the metering device works, two-phase flow enters through the inlet pipeline 1 and enters the fluid rectifying filter 3 through the climbing pipeline 2 and the rectifier connecting pipeline 8. Because the inner diameter of the fluid rectifying filter 3 is larger than the inner diameters of the climbing pipeline 2 and the straight pipe section 4 before the flowmeter, when the two-phase flow fluid enters the fluid rectifying filter 3, the two-phase flow fluid can be fully rectified and mixed in the fluid rectifying filter 3 due to instantaneous expanding. The rectified two-phase flow enters the front straight pipe section 4 of the flowmeter, the pipe diameter is reduced for transition, and therefore the two-phase flow is fully mixed when passing through the gas-liquid two-phase flowmeter 5 and has a relatively stable flow state. At this time, the gas-liquid two-phase flow meter 5 measures the two-phase flow. The two-phase flow fluid after metering passes through the rear straight pipe section 6 of the flowmeter and the outlet pipeline 7 and flows out of the flowmeter.
The above-mentioned embodiments only express the specific embodiments of the present invention, and the description thereof is more specific and detailed, but not construed as limiting the scope of the present invention. It should be noted that, for a person skilled in the art, several variations and modifications can be made without departing from the inventive concept, which falls within the scope of the present invention.
