Description

Technical Field

[0001] This utility model relates to the field of testing equipment technology, and in particular to a fluid testing device. Background Technology

[0002] In industrial fluid testing equipment (such as separation efficiency test benches and heat exchange performance test benches), liquid collection bags are common components used to collect the liquid media generated during the test. However, because the position of the liquid collection bag is fixed, this fixed structure is difficult to adapt effectively when the test needs to handle fluids with different densities (such as lighter hydrocarbons with lower density or higher-density high-concentration brine and oil products). Utility Model Content

[0003] This invention provides a fluid testing device to address the deficiency of fixed position of the liquid collection bag in the prior art. Through the reconfigurable connection design of the pretreatment component and the coalescing separation component, the coalescing separation component can form multiple spatial connection postures, thereby giving the liquid collection bag inside the coalescing separation component variability in position relative to the coalescer.

[0004] The fluid testing equipment provided by this utility model includes:

[0005] A pretreatment component, which is provided with a material inlet and a first connection part, is used to pretreat fluids;

[0006] A coalescing separation assembly is provided with a second connection portion and a material outlet, the second connection portion matching the first connection portion so that the coalescing separation assembly has at least two spatial connection postures relative to the pretreatment assembly, the coalescing separation assembly being used to perform coalescing separation treatment on the fluid.

[0007] According to the fluid testing equipment provided by this utility model, the coalescence separation component includes:

[0008] A coalescer is provided, which is horizontally positioned and rotatable about its own axis. A second connecting part is provided at one end of the coalescer, and the first connecting part, the second connecting part, and the coalescer are coaxial. A material outlet is provided at the coalescer, which is used to perform coalescence separation processing on the fluid.

[0009] A liquid collection bag is connected to the coalescer. The end of the liquid collection bag away from the coalescer is provided with a heavy phase outlet. The liquid collection bag is used to collect the fluid separated by the coalescer.

[0010] According to the fluid testing equipment provided by this utility model, the first connecting part includes a first axisymmetric flange interface, the second connecting part includes a second axisymmetric flange interface, the second axisymmetric flange interface matches the first axisymmetric flange interface, and the first axisymmetric flange interface, the second axisymmetric flange interface and the coalescer are coaxial.

[0011] According to the fluid testing equipment provided by this utility model, the first axisymmetric flange interface is a circular flange interface, and the second axisymmetric flange interface is a circular flange interface.

[0012] According to the fluid testing equipment provided by this utility model, the liquid collection bag is provided with at least two observation windows, which are used to observe the fluid separation effect;

[0013] And / or, the collection bag includes a transparent body for observing the fluid separation effect.

[0014] According to the fluid testing equipment provided by this utility model, the pretreatment component includes:

[0015] A feed head, wherein the material inlet is located at the feed head;

[0016] A filter, connected to the feed head flange, is used to filter the fluid;

[0017] A connecting pipe is connected to the filter flange, and the first connection part is located at the end of the connecting pipe away from the filter.

[0018] According to the fluid testing equipment provided by this utility model, the filter is set horizontally.

[0019] According to the fluid testing equipment provided by this utility model, at least two valves are provided between the feed head and the filter;

[0020] And / or, at least two valves are respectively provided at the material outlet and the heavy phase outlet.

[0021] The fluid testing equipment provided by this utility model also includes:

[0022] A first pressure detection element is disposed in the coalescer, and the first pressure detection element is used to detect the pressure at the inlet of the coalescer;

[0023] A second pressure detection element is disposed in the connecting pipe, and the second pressure detection element is used to detect the pressure inside the connecting pipe;

[0024] A third pressure detection element is disposed in the coalescer, and the third pressure detection element is used to detect the pressure at the outlet of the coalescer.

[0025] The fluid testing equipment provided by this utility model also includes:

[0026] The first sampling port is located at the feed head;

[0027] The second sampling port shares an external pipeline with the material outlet and is connected to the coalescer.

[0028] The fluid testing equipment provided by this invention utilizes a reconfigurable connection design between the pretreatment component and the coalescing separation component, enabling the coalescing separation component to form various spatial connection postures. This gives the positional variability of the liquid collection bag within the coalescing separation component relative to the coalescer. When the liquid collection bag is located below the coalescer, its gravity settling path aligns with the natural movement direction of the high-density dispersed phase fluid (such as brine or heavy oil), efficiently capturing and collecting this heavy phase. When the liquid collection bag is adjusted to the upper side of the coalescer, it follows the upward floating trend of the low-density dispersed phase fluid (such as light hydrocarbons), achieving active aggregation of the light phase. This adaptive separation mechanism based on density difference allows a single set of equipment to dynamically match the phase separation behavior of fluids with different densities.

[0029] Compared to the rigidity inherent in the fixed position of the collection bag in the prior art—that is, its inability to simultaneously accommodate fluids with significant density differences (such as light hydrocarbons and high-concentration brine)—this solution improves the separation efficiency loss caused by the rigid structure of traditional equipment by allowing free switching of the spatial connection posture. Specifically, when processing fluids with non-design density, traditional equipment suffers from liquid phase residue due to the mismatch between the direction of dispersed phase movement and the position of the collection bag (for example, the light phase cannot settle to the lower collection bag, or the heavy phase cannot float to the upper collection bag). In contrast, this solution ensures that the dispersed phase always enters the collection area along the optimal path through the adjustable relative position of the collection bag and the coalescer, thereby effectively improving the separation thoroughness and operational reliability under various operating conditions.

[0038] Figure 1 This is a schematic diagram of the pipeline connection of the fluid testing equipment provided in this embodiment of the utility model.

[0039] See Figure 1 This utility model provides a fluid testing device, which mainly includes a pretreatment component 100 and a coalescing and separating component 200. The pretreatment component 100 is provided with a material inlet 110 and a first connecting part 120 (such as a flange) for pretreatment operations such as solid particulate interception on the input fluid.

[0040] The coalescing separation component 200 is provided with a second connecting part 210 (e.g., a flange that matches the first connecting part 120) and a material outlet 220. Through the docking of the first connecting part 120 and the second connecting part 210, the coalescing separation component 200 can form a variety of spatial connection postures relative to the pretreatment component 100.

[0041] For example, in one connection configuration, after the pretreatment component 100 and the coalescing and separating component 200 are connected by the first connecting part 120 and the second connecting part 210, the liquid collection bag 240 in the coalescing and separating component 200 is located below the coalescer 230; or, based on the aforementioned example, the angles of the first connecting part 120 and the second connecting part 210 are changed so that the liquid collection bag 240 in the coalescing and separating component 200 is located above the coalescer 230.

[0042] When the collection bag 240 is located below the coalescer 230, it is suitable for collecting dispersed phase fluids with a density greater than that of the continuous phase; when the collection bag 240 is located above the coalescer 230, it is suitable for collecting dispersed phase fluids with a density less than that of the continuous phase. It should be noted that the above two examples are merely one of two spatial connection postures of the coalescing separation component 200 in this embodiment. The coalescing separation component 200 can achieve various selectable spatial postures through the connection angle or method of the first connecting part 120 and the second connecting part 210, thereby realizing the separation and collection of different fluids under various operating conditions.

[0043] In use, the fluid is pretreated by the pretreatment component 100 and then enters the coalescence separation component 200. The dispersed phase droplets coalesce and grow in the coalescer 230, and phase separation is achieved based on the density difference. When the collection bag 240 is located below the coalescer 230, the heavier liquid phase (such as the aqueous phase) sinks to the collection bag 240. When the collection bag 240 is located above the coalescer 230, the lighter liquid phase (such as light oil) floats to the collection bag 240. The separated continuous phase is discharged from the material outlet 220.

[0044] See Figure 1 It is understood that in the fluid testing equipment provided in this embodiment of the present invention, the reconfigurable connection design between the pretreatment component 100 and the coalescing separation component 200 enables the coalescing separation component 200 to form multiple spatial connection postures, thereby giving the liquid collection bag 240 inside the coalescing separation component 200 positional variability relative to the coalescer 230. When the liquid collection bag 240 is located below the coalescer 230, its gravity settling path is consistent with the natural movement direction of the high-density dispersed phase fluid (such as brine, heavy oil), which can efficiently capture and collect such heavy phases; while when the liquid collection bag 240 is adjusted to the upper side of the coalescer 230, it follows the floating trend of the low-density dispersed phase fluid (such as light hydrocarbons), realizing the active aggregation of the light phase; this adaptive separation mechanism based on density difference enables a single set of equipment to dynamically match the phase separation behavior of fluids with different densities.

[0045] Compared to the rigidity inherent in the fixed position of the collection pack 240 in the prior art—that is, its inability to simultaneously accommodate fluids with significant density differences (such as light hydrocarbons and high-concentration brine)—this solution improves the separation efficiency loss caused by the rigid structure of traditional equipment by allowing free switching of the spatial connection posture. Specifically, when processing fluids with non-design density, traditional equipment suffers from liquid phase residue due to the mismatch between the direction of dispersed phase movement and the position of the collection pack 240 (for example, the light phase cannot settle to the lower collection pack 240, or the heavy phase cannot float to the upper collection pack 240). This technology, through the adjustable relative position of the collection pack 240 and the coalescer 230, ensures that the dispersed phase always enters the collection area along the optimal path, thereby effectively improving the thoroughness of separation and operational reliability under various operating conditions.

[0046] Continue reading Figure 1 In an optional embodiment of this utility model, the coalescing separation assembly 200 includes a horizontally arranged coalescer 230 and a collection bag 240 connected thereto. The coalescer 230 is rotatable about its own axis and is provided with a second connecting part 210 (such as a flange) and a material outlet 220, and the first connecting part 120, the second connecting part 210 and the coalescer 230 are coaxially aligned. The collection bag 240 is fixedly connected to the outside of the coalescer 230, and its end away from the coalescer 230 is provided with a heavy phase outlet 241 for collecting the separated dispersed phase fluid.

[0047] In an alternative embodiment, the coalescer 230 can be supported on a bracket by bearings, and the operator can manually rotate the housing of the coalescer 230 (e.g., by gripping the anti-slip texture on the surface of the housing) to change the circumferential position of the collection bag 240 around the axis.

[0048] In use, if it is necessary to change the relative position of the collection bag 240, while keeping the pretreatment component 100 and the coalescer 230 aligned through the first connection 120 and the second connection 210, directly rotate the coalescer 230 (along with the collection bag 240) around the axis to the target angle (e.g., 180°). After rotation, the position of the collection bag 240 changes, but the internal flow channel of the coalescer 230 remains connected to the pretreatment component 100. Accordingly, when the collection bag 240 is lowered, the heavy phase settles into the collection bag 240; when the collection bag 240 is uppered, the light phase floats to the collection bag 240. The fluid channel is not damaged during the rotation, and the test can be resumed directly after adjustment without resealing or disassembling the pipeline.

[0049] See Figure 1 It is understood that in the fluid testing equipment provided by this utility model embodiment, the orientation of the liquid collection bag 240 can be changed by rotating a single component (from lower to upper, or other directions and angles), without adjusting the support or disconnecting the pipeline, thus overcoming the cumbersome nature of traditional equipment requiring overall reconstruction; secondly, the coaxial design ensures that the sealing surfaces of the first connecting part 120 and the second connecting part 210 remain in a pressed state during rotation, eliminating the need for a secondary alignment step.

[0050] In an optional embodiment of this utility model, the first connecting part 120 is specifically a first axisymmetric flange interface (such as a circular flange, rectangular flange, or elliptical flange), with its sealing surface and bolt holes evenly distributed circumferentially; the second connecting part 210 is a second axisymmetric flange interface (of the same specification, such as a circular flange, rectangular flange, or elliptical flange) that matches the first axisymmetric flange interface. The first axisymmetric flange interface, the second axisymmetric flange interface, and the coalescer 230 maintain a coaxial relationship, that is, their central axes coincide. For example, the sealing surfaces of the first axisymmetric flange interface and the second axisymmetric flange interface are concentric rings, and the bolt holes are distributed at equal angles along the circumference (such as 8 holes evenly distributed at 45°), ensuring complete fit at any rotation angle.

[0051] When the position of the collection bag 240 needs to be adjusted, the first axisymmetric flange interface and the second axisymmetric flange interface always remain in a mating state. Loosen the flange bolts (without completely disassembling) and manually rotate the coalescer 230 to the target angle (such as 180°). At this time, because the flange interface is axisymmetric, the bolt holes can still be aligned after rotation. Tighten the bolts, and the position switching of the collection bag 240 is completed. The fluid channel sealing is not damaged throughout the process, and the internal flow channel of the coalescer 230 is always coaxially connected with the outlet of the pretreatment component 100.

[0052] See Figure 1 Understandably, compared to threaded connections, the first and second axisymmetric flange interfaces can reduce the risk of leakage; secondly, the axisymmetric characteristics eliminate the need for angle calibration, allowing operators to quickly complete rotational reconfiguration without precise alignment.

[0053] In an optional embodiment of this utility model, both the first axisymmetric flange interface and the second axisymmetric flange interface are specifically circular flange interfaces. The sealing surfaces of the circular flange interfaces are continuously distributed in an annular shape, and the bolt holes are arranged at equal angles along the circumference.

[0054] When the rotating coalescer 230 adjusts the position of the liquid collection bag 240, loosen the bolts between the first axisymmetric flange interface and the second axisymmetric flange interface (without complete disassembly); rotate the coalescer 230 and the liquid collection bag 240 around the axis to the target angle (such as 90°, 180°, etc.); due to the continuous axisymmetric characteristics of the circular flange interface, the bolt holes can be completely overlapped after any angle of rotation, and the seal can be restored by directly retightening the bolts. In this process, the geometric symmetry of the circular sealing surface eliminates the need for angle calibration, and the coaxiality of the fluid channel remains unchanged after rotation.

[0055] It is understood that in the fluid testing equipment provided by this utility model embodiment, the annular sealing surface makes the flange clamping force evenly distributed along the circumference, which can effectively reduce the risk of local leakage under high pressure conditions compared with discontinuous sealing surfaces (such as elliptical flanges); secondly, it supports arbitrary angle adjustment (such as 45°, 120°, etc.), and is not limited to a specific position of 180°, which facilitates fine adjustment of the liquid collection bag 240 degrees to adapt to complex separation requirements; in addition, standard circular flanges can be used, and existing pipeline seals can be directly reused, reducing manufacturing and maintenance costs.

[0056] Continue reading Figure 1 In optional embodiments of this utility model, the liquid collection bag 240 is provided with a visual observation structure. Option A: At least two observation windows 242 (such as symmetrically distributed borosilicate glass sight glasses) are provided on the shell of the liquid collection bag 240, and the center line of the window is perpendicular to the axis of the liquid collection bag 240. Option B: The liquid collection bag 240 is made of a transparent body (such as a borosilicate glass cylinder). Combined option: It includes both symmetrical windows and a transparent body.

[0057] When the equipment is running, the operator can observe the fluid stratification (such as the oil-water interface) inside the collection bag 240 from two symmetrical perspectives through two observation windows 242, eliminating blind spots in observation on one side; or directly observe the fluid separation state in 360° around the transparent body; regardless of whether the collection bag 240 is below (collecting heavy phase) or above (collecting light phase) the coalescer 230, the observation structure can provide an unobstructed field of view.

[0058] It is understood that in the fluid testing equipment provided by this utility model embodiment, the symmetrical layout of the dual windows cancels out the refractive error of single-sided observation, making the liquid level stratification reading more accurate; the transparent body or the dual-window structure can maintain effective observation in any position (upper / lower) of the liquid collection bag 240, and can maintain the matching with the aforementioned coalescer 230 rotation function; in addition, the separation effect can be confirmed in real time by visual observation structure, which can avoid pressure fluctuations caused by excessive liquid collection, and is suitable for risk control of hazardous media such as vinyl chloride.

[0059] Continue reading Figure 1 In an optional embodiment of this utility model, the pretreatment component 100 is a modular unit consisting of a feed head 130, a filter 140, and a connecting pipe 150. The feed head 130 is provided with a material inlet 110 (such as a flange interface) for receiving the fluid to be treated; the filter 140 is connected to the feed head 130 via a flange, and has a built-in replaceable filter element for solid interception; one end of the connecting pipe 150 is flanged to the outlet of the filter 140, and the other end is provided with a first connecting part 120 (such as a circular flange interface) for connecting to the coalescence separation component 200.

[0060] The fluid processing flow is as follows: the fluid to be tested enters through the material inlet 110 of the feed head 130; when flowing through the filter 140, solid particles are trapped by the filter element; the purified fluid is transported to the first connecting part 120 through the connecting pipe 150, and then enters the coalescence separation component 200. When the filter 140 needs to be maintained, only the corresponding flange bolts need to be removed to replace the filter element, without the need to completely disassemble the pretreatment component 100.

[0061] It is understood that in the fluid testing equipment provided by this utility model embodiment, the pretreatment component 100 can be independently replaced or upgraded (such as replacing filter elements of different precision) through the standardization of the flange interface, so that a single device can support multiple functions such as filtration testing and separation testing, overcoming the single function of the traditional fixed series structure; in addition, the flange sealing structure is adapted to high pressure conditions, which can eliminate the risk of leakage of threaded connections under hazardous media (such as vinyl chloride).

[0062] In an optional embodiment of this utility model, the filter 140 is horizontally arranged with its axis parallel to the ground. As the core connecting unit of the pretreatment component 100, the filter 140 is connected at both ends to the outlet of the feed head 130 and the inlet of the connecting pipe 150 via flanges, forming a straight flow path layout.

[0063] Understandably, by eliminating the vertical space occupied by the vertical layout through the horizontally set filter 140, the cross-sectional size of the pretreatment component 100 can be minimized, which is conducive to the compact layout of the whole machine. Secondly, after removing the flange bolts of the filter 140, the filter element can be pulled out horizontally without the need for upper operating space, which is conducive to maintenance.

[0064] Continue reading Figure 1 In optional embodiments of this utility model, the fluid testing equipment is equipped with a multi-valve safety isolation structure. Scheme A: At least two valves are connected in series in the pipe section between the feed head 130 and the filter 140; Scheme B: Double valve groups are respectively installed at the material outlet 220 and the heavy phase discharge outlet 241; Combined scheme: Scheme A and Scheme B are implemented simultaneously.

[0065] For example, the feed section has two valves: the inlet valve (stainless steel ball valve) is close to the feed head 130, and the first isolation valve (needle valve) is close to the filter inlet 140; the outlet has two valve groups: the material outlet 220 is connected in series with the outlet valve (ball valve) and the second isolation valve, and the heavy phase discharge outlet 241 is connected in series with the discharge valve (ball valve) and the third isolation valve (ball valve).

[0066] During operation, all valves are open, and the fluid flows sequentially through the feed head 130 → dual valves → filter 140 → coalescing separation component 200 → outlet dual valves. When maintenance is required in the feed section, the inlet valve and the first isolation valve are closed to form a double sealing barrier; when discharging harmful media, the drain valve and the third isolation valve are closed to prevent residual fluid leakage; if a single valve fails, the backup valve can still provide sealing protection.

[0067] See Figure 1 It is understood that in the fluid testing equipment provided by this utility model embodiment, the dual valves connected in series can form a physical isolation zone. Even if a single seal fails, the leakage of the medium can still be blocked by the second valve, effectively reducing the probability of leakage of harmful media. Secondly, when disassembling the filter 140 or the liquid collection bag 240, the dual valve isolation eliminates the need for system depressurization and can directly cut off the upstream and downstream fluid passages.

[0068] Continue reading Figure 1 In an optional embodiment of this utility model, the fluid testing equipment is equipped with a distributed pressure monitoring system. A first pressure detection element 300 (such as a pressure gauge) is installed at the inlet end of the coalescer 230 to monitor the fluid pressure entering the coalescer 230; a second pressure detection element 400 (such as a pressure gauge) is installed in the middle of the connecting pipe 150 to monitor the delivery pressure of the pretreated fluid; and a third pressure detection element 500 (such as a pressure gauge) is installed in the middle of the coalescer 230 housing to monitor the internal pressure during the coalescence separation process.

[0069] Real-time data acquisition: The second pressure sensor 400 monitors the outlet pressure of filter 140 (P1); the first pressure sensor 300 monitors the inlet pressure of coalescer 230 (P2); the third pressure sensor 500 monitors the working pressure of coalescer 230 (P3).

[0070] Differential pressure analysis: Pressure loss of filter 140: ΔP1=P1-P2 (reflects the degree of filter element clogging); Pressure loss of coalescer 230: ΔP2=P2-P3 (indicates the condition of coalescing filter element).

[0071] See Figure 1 It is understood that the fluid testing equipment provided in this embodiment of the present invention has three measuring points covering the pressure changes throughout the entire process, which can verify the pressure bearing status of the equipment in real time and meet the testing requirements of the industry standard. Secondly, through the correlation analysis of ΔP1 and ΔP2, the filter element clogging stage can be determined, avoiding the risk of premature replacement or crushing caused by the reliance on experience estimation in traditional equipment. In addition, the redundancy design of the three measuring points can ensure that key pressure data can still be obtained in the event of a single failure, and can achieve continuous safety monitoring of hazardous media such as vinyl chloride.

[0072] Continue reading Figure 1 In an optional embodiment of this utility model, the fluid testing equipment is equipped with a dual-point sampling system. The first sampling port 600 is directly set on the side wall of the feed head 130 for collecting the original fluid sample; the second sampling port 700 shares the same external pipe with the material outlet 220 of the coalescer 230.

[0073] Optionally, the first sampling port 600 is an independent short pipe welded to the feed head 130, with a ball valve at the end for control; the second sampling port 700 is a tee joint installed on the material outlet 220 pipe, with a sampling valve installed on the branch pipe.

[0074] In use, open the valve of the first sampling port 600 to directly obtain the raw fluid entering the pretreatment component 100; close the material outlet 220 valve (when the second sampling port 700 and the material outlet 220 share a three-way valve), and open the valve of the second sampling port 700 to allow the coalesced fluid to flow out from the sampling branch; or keep the outlet valve open (when the second sampling port 700 and the material outlet 220 share a three-way pipe and each has an independent valve), and simultaneously output and sample through the three-way diversion.

[0075] See Figure 1 It is understood that in the fluid testing equipment provided by this utility model embodiment, the separation efficiency can be directly quantified by the sample composition (such as free water content) through the first sampling port 600 and the second sampling port 700, overcoming the problem that traditional single-point sampling cannot trace the separation process; secondly, the second sampling port 700 reuses the pipe of the material outlet 220, which can avoid additional openings in the shell of the coalescer 230, reducing the complexity of the equipment and maintenance costs.

[0076] In an optional embodiment of this utility model, the fluid testing equipment is made entirely of 304 stainless steel to ensure the corrosion resistance of the structure. Alternatively, other corrosion-resistant materials can be used to ensure the safety of the fluid testing equipment. Specifically, the appropriate material can be selected based on the actual situation.

[0077] In an optional embodiment of this invention, to ensure safety and sealing performance during testing of extremely hazardous media (such as vinyl chloride, benzene, cyanide, etc.), flange connections are used between pipelines, containers, instruments (pressure gauges, etc.), and all pipelines and containers are inspected for defects after welding. To ensure good sealing safety and operational reliability, all connecting valves are stainless steel ball valves.
