Abstract
A scraper-type gas-liquid two-phase flow proportional sampler mainly comprises an inlet pipe, a partition plate, a scraper, a main flow chamber, a sampling groove, a sampling fluid outlet pipe, a main fluid outlet pipe and the like. When two-phase fluid flows through the sampler, the partition plate and the scraper plate are driven to rotate, so that the two-phase fluid can periodically flow to a sampling chamber and a main flow chamber according to a certain time share, and then respectively flow into the branch fluid loop and the main fluid loop. The sampling ratio depends only on the ratio of the sampling chamber inlet area to the total circumferential area. Compared with the existing gas-liquid two-phase flow sampling device, the continuous flow distribution of the invention ensures that the two-phase fluid flowing into the sampling chamber and the main flow chamber has highly consistent phase content and flow, is not influenced by parameters such as inlet gas-liquid phase flow velocity, flow pattern and the like, has more representative sampling, and has the advantages of difficult blockage, strong adaptability and the like.
Description
The technical field is as follows:
the invention belongs to the field of two-phase fluid distribution, and particularly relates to a scraper type gas-liquid two-phase flow proportional sampler.
Background art:
the gas-liquid two-phase flow is widely applied to the industrial fields of petroleum, chemical industry, nuclear power, water conservancy and the like, compared with single-phase flow, the gas-liquid two-phase flow process is often accompanied with a strong fluctuation phenomenon, and the flow pattern has various flow patterns such as stratified flow, slug flow, annular flow and the like along with the difference of gas-liquid phase flow and components, so that the flow measurement of the gas-liquid two-phase fluid is very difficult.
The efficient and accurate measurement of the flow of the two-phase fluid is a problem which needs to be solved urgently but cannot be solved well in the relevant industrial field. At present, in the field of gas-liquid two-phase flow metering, various metering methods such as a complete separation method, a non-separation method and a split-flow phase-splitting method exist.
The principle of the complete separation method, as a traditional two-phase fluid measurement method, is to separate a gas-liquid mixture into single-phase gas and single-phase liquid by using separation equipment, and then measure the flow by using a single-phase flowmeter respectively. The complete separation method has the advantages of reliable work, wide measurement range, high measurement precision and the like, but the defects of large size and high construction cost of the separation equipment limit the wide application of the complete separation method in oil and gas gathering and transportation occasions such as offshore platforms, deserts and the like.
The non-separation method is a method for directly measuring the flow and the composition of gas and liquid phases by using a measuring instrument. Most of multiphase flow meters currently used in the industrial field are based on such a non-separation online measurement method, and the principle thereof is to obtain gas-liquid two-phase flow by measuring phase flow rate and phase fraction, including MFM-2000 multiphase flow meter of himmer, langu, VX spectroscopic multiphase flow meter of schlumberger, Roxar multiphase flow meter of Emerson, and the like. The non-separation type online metering method has the advantages of small volume, high precision and the like, but the price is high, the application range is limited, and therefore the application in multiphase flow monitoring is less.
The principle of the split-flow split-phase gas-liquid two-phase fluid measuring method is that a certain portion of two-phase fluid is proportionally split from the measured fluid, the fluid is separated into single-phase gas and single-phase liquid by a small separator, and after the single-phase fluid is measured by a single-phase flowmeter, the phase flow of the two-phase fluid is calculated according to the proportional relation. The method greatly reduces the size of the separator and has the advantages of high measurement precision, wide measurement range and the like.
To achieve uniform distribution, Wangman et al propose a runner type sampling distributor based on the time-sharing principle (Wangman, Zhang Xiujian, Liangfachun, Linzonghu. multiphase fluid proportion distribution method [ J ] based on the time-sharing principle, engineering thermophysics, 2005(S1): 101-. The basic principle is that incoming flow is converted into rotating jet flow through a rotating wheel, and then fluid receiving chambers of a main flow loop and a branch flow loop are sequentially arranged around the outer edge of the rotating wheel. With the rotation of the rotating wheel, most of the multiphase fluid jet flow enters the main fluid collecting chamber and flows to the main fluid loop, a small part of the sampling fluid enters the shunt fluid collecting chamber and flows to the shunt loop, then enters the two-phase flow separator for separation and metering, and then the main fluid flow is calculated according to the shunt ratio. The rotating wheel type sampling distributor can overcome the impact of instability of two-phase fluid on rotation, ensures the representativeness of sampling, but when the gas phase content of the two-phase fluid is high, the vibration of the rotating wheel can cause abrasion, the requirement on the cleanliness of the fluid is high, and certain disadvantages are realized during application.
In order to overcome the defects of the prior art, the invention provides a scraper type gas-liquid two-phase flow proportional sampler. When a two-phase fluid flows into the sampler, a pressure difference is generated between the inlet and the outlet of the sampler to drive the partition and the scraper to rotate. The inner cavity of the shell of the sampler, the pair of partition plates and the pair of scrapers form a fluid chamber, and the two-phase fluid can sequentially fill each fluid chamber along with the rotation of the partition plates. In particular, a sampling slot is opened in one of the fluid chambers (hereinafter referred to as the sampling chamber), the fluid in the sampling chamber will enter the sampling fluid collecting cylinder through the sampling slot and then enter the shunt circuit, and the rest of the fluid enters the main circuit. The sampler takes one sample per revolution of the partition plate, and the sampling ratio of the sampler is only determined by the proportion of the inlet area of the sampling chamber to the total circumferential area. Compared with the existing gas-liquid two-phase flow sampling device, the sampling device has the advantages of small volume, compact structure, strong adaptability and the like, is not influenced by parameters such as inlet gas-liquid two-phase flow velocity, flow pattern and the like, is not easy to block, and can be applied to the metering of the two-phase fluid containing solid impurities.

The specific implementation mode is as follows:
as shown in fig. 1 and 2, the present invention mainly comprises a housing 1, an inlet pipe 2, a main fluid outlet pipe 10 and a sampling fluid outlet pipe 13, wherein the inlet pipe 2 and the main fluid outlet pipe 10 are coaxially arranged and symmetrically distributed on two sides of the housing 1, and are respectively communicated with an inner cavity of the housing 1.
As shown in fig. 3, a rotating shaft 11 and a stop block 9 are arranged in the closed inner cavity of the shell 1; the stop 9 is in an 1/4 circular ring structure, is arranged on the inner wall of the shell 1 between the inlet pipe 2 and the main fluid outlet pipe 10 and keeps jointed with the inner wall. The rotating shaft 11 is positioned in the center of the inner cavity of the shell 1, and the center of the rotating shaft 11 is provided with a sampling fluid collecting cylinder 5. A plurality of partition plates 6 are uniformly arranged on the side wall of the rotating shaft 11 along the circumferential direction, and scraping plates 8 are installed at the tail ends of the partition plates 6. The space between the inner wall surface of the shell 1 and the outer wall surface of the rotating shaft 11 is divided into a plurality of chambers by the partition plates 6 and the scraping plates 8, wherein one chamber is a sampling chamber 3, and the rest chambers are main flow chambers 12. A rectangular sampling groove 4 is formed in the side wall of the rotating shaft 11 between two adjacent partition plates 6 of the sampling chamber 3, and the sampling groove 4 is communicated with the sampling chamber 3 and the sampling cylinder 5.
By way of example, in fig. 3 there are eight baffles 6 and eight scrapers 8, the baffles 6 and their end scrapers 8 dividing the interior of the housing 1 into eight chambers. A rectangular sampling groove 4 is formed in the side wall of a rotating shaft 11 between two partition plates 6, the cavity is called as a sampling chamber 3, and the rest seven cavities are called as main flow chambers 12. Fluid entering sampling chamber 3 flows through sampling slot 4 into sampling fluid collection cartridge 5.
As shown in fig. 4, the scraper 8 is connected with the partition 6 through the hinge torsion spring 7, when the scraper 8 meets the stopper 9, the scraper 8 can rotate, and after passing through the stopper 9, the scraper 8 can rebound immediately and always keeps in contact with the upper edge of the partition 6 and the wall surface of the inner cavity of the housing 1.
As shown in fig. 5, the sampling fluid collecting cylinder 5, the sampling fluid outlet pipe 13 and the rotating shaft 11 are coaxially arranged, and the sampling fluid outlet pipe 13 communicates with the sampling fluid collecting cylinder 5. The upper sealing end cover 15 and the lower sealing end cover 16 are fixedly connected with the top end face and the bottom end face of the partition plate 6. The upper sealing end cover 15 and the lower sealing end cover 16 are connected with the shell 1 through sliding bearings 14, so that the upper sealing end cover 15 and the lower sealing end cover 16 can rotate along with the partition plate 6. The lower end cap 16 is covered with a bottom end cap 17, and the sampling fluid outlet pipe 13 is installed at the center of the bottom end cap 17. When the two-phase fluid passes through the sampler, the sampling fluid collecting cylinder 5 rotates along with the rotating shaft 11, and the sampling fluid outlet pipe 13 is fixedly arranged at the center of the bottom end cover 17 and does not rotate along with the rotation.
In addition, a layer of wear-resistant rubber is arranged on the connecting surface of the upper edge of the scraper 8 and the inner cavity of the shell 1, and the connecting surfaces of the scraper 8, the upper sealing end cover 15 and the lower sealing end cover 16, so that the scraper 8 and the inner cavity of the shell 1, and the scraper 8 and the upper sealing end cover 15 and the lower sealing end cover 16 are elastically connected.
The working principle of the invention is illustrated as follows:
when the two-phase fluid to be measured enters the sampler interior from the inlet pipe 1, as shown in fig. 3 and 5, a pressure differential is created between the inlet and outlet of the sampler, which pressure differential pushes the diaphragm 6 and scraper 8 into rotation. By way of example, the interior of the housing 1 of the sampler, eight baffles 6 and eight scrapers 8 constitute one sampling chamber 3 and seven main flow chambers 12. The sampling chamber 3 and each of the mainstream chambers 12 will be sequentially filled with the same volume of two-phase fluid for each revolution of the partition 6. Specifically, inside sampling chamber 3, a rectangular sampling slot 4 is opened on rotating shaft 11, and the two-phase fluid in sampling chamber 3 will enter sampling fluid collecting cylinder 5 through sampling slot 4 and then enter sampling fluid outlet pipe 13. Fluid entering the remaining seven main flow chambers 12 enters the main fluid outlet pipe 10. It can be seen that the sampler divides the incoming gas-liquid flow into two parts, one part entering the sample fluid outlet pipe 13 and the other part entering the main fluid outlet pipe 10.
As shown in fig. 6, the fluid entering the sampling fluid outlet tube 13 eventually flows into the shunt fluid circuit 20. Additionally, the two-phase fluid in the seven main flow chambers 12 will flow into the main fluid outlet pipe 10 as the partition 6 and the scraper 8 rotate, and eventually into the main fluid circuit 19. The sampler finishes sampling once every time the clapboard 6 rotates for one circle, and the sampling is repeated in cycles to finish the uniform sampling work of the two-phase fluid.
The present invention ensures consistent phase content and defined sampling ratios of the sampled fluid and the upstream main fluid. The concrete description is as follows:
as shown in fig. 3, after entering the sampler cavity through the inlet pipe 2, the two-phase fluid flows into one fluid chamber in a short time and flows into the other fluid chamber in the next time interval, and the distribution is periodically and alternately circulated. Wherein, the two-phase fluid flowing into the sampling chamber 3 and then flowing into the sampling fluid outlet pipe 13 through the sampling slot 4 is the sampling fluid and finally enters the shunt fluid loop. Additionally, the primary fluid flowing into the primary fluid chamber 12 and then into the primary fluid outlet pipe 10 is the primary fluid, and eventually enters the primary fluid circuit. In the distribution process, the process of alternately switching distribution does not exert any additional action on the two-phase flow, so the flow mode and the flow rate are not influenced, and the distribution process of the two-phase flow is close to the continuous flow distribution process. Thus, when various flow patterns of the two-phase fluid are met, the two-phase fluid entering each fluid chamber can be ensured to have highly consistent phase content and two-phase flow. In this case, the diversion ratio is related only to the proportion of the distribution time, which is equal to the ratio of the diversion time to the total time. In the present invention, the split ratio is equal to the ratio of the sampling chamber inlet area to the total circumferential area, specifically, the sampling chamber 3 to the total fluid chamber.
If the rotation period of the partition plate 6 is T, i.e., the time during which the eight fluid chambers are sequentially filled with the two-phase fluid is T, and the time during which the two-phase fluid flows into one sampling chamber 3 is Δ T, the split ratio can be expressed as:
if the baffle 6 is rotating at a uniform speed, the split ratio is numerically equal to the ratio of the sampling chamber inlet area to the total circumferential area. The invention realizes the two-phase flow metering based on the principle. Two streams flow through main conduit 18 into the sampler of the present invention, wherein the main fluid enters main fluid loop 19 through main fluid outlet conduit 10 and the sample fluid enters sub-fluid loop 20 through sample fluid outlet conduit 13. The sampled fluid then enters a small gas-liquid two-phase separator 21 for separation, and the separated gas phase fluid is separately metered by a gas flow meter 22, and the separated liquid phase fluid is separately metered by a liquid flow meter 23. Thus, the gas phase flow and the liquid phase flow of the sampled fluid can be obtained, and the gas-liquid phase flow of the total gas-liquid two-phase fluid can be calculated according to the split ratio. Finally, the metered gas phase and liquid phase fluids are recombined and flow into the main pipeline.
In conclusion, the invention can realize the sampling function of the gas-liquid two-phase fluid, when the gas-liquid two-phase fluid passes through the sampling device, the sampling ratio only depends on the proportion of the inlet area of the sampling chamber to the total circumferential area, the sampling device is not influenced by the flow pattern of the two-phase fluid in the pipeline, the flow velocity of the gas-liquid phase and the like, the sampling device has wide applicability, the continuous flow distribution ensures that the two-phase fluid flowing into the fluid chamber has high consistent phase content and flow, and the sampling is more representative.
