Description

Technical Field

[0001] This utility model relates to the field of gas-liquid separation technology and is an embedded folded gas-liquid two-phase separator. Background Technology

[0002] Gas-liquid two-phase separation technology plays a crucial role in various industrial fields such as petrochemicals and energy, serving as a fundamental step in ensuring the efficient and stable operation of production processes. In these complex industrial production processes, the efficient separation of gas and liquid directly impacts the overall system efficiency and product quality. Traditional separators primarily rely on gravity settling or a single cyclone structure to achieve gas-liquid separation. However, these traditional methods have revealed several shortcomings in practical applications. For example, the equipment is bulky, consuming significant space and increasing the difficulty of installation and maintenance. Furthermore, the phase separation effect is not thorough enough, resulting in the separation of gas and liquid potentially containing impurities that can affect subsequent processes.

[0003] Taking the styrene process as an example, accurate monitoring of acetylene absorption rate and carbon dioxide release during catalyst activation is crucial, as it directly affects the optimization of process parameters and the stability of product quality. However, in actual operation, the high moisture content commonly found in sample gases poses a significant challenge to monitoring. To address this issue, a vapor-water separator is typically installed on the analyzer's inlet line to initially remove moisture. However, a common design oversight is that these separators often lack a corresponding condensate drainage system. Consequently, the separated condensate can only be directly discharged to the ground, causing environmental pollution, damaging the surrounding area, and potentially posing hazards to soil and groundwater. This also exposes the inadequacy of existing water removal measures.

[0004] A deeper problem lies in the fact that the overall water removal efficiency of the entire pretreatment system, including its pipelines, filters, and even separators, often fails to meet expectations. This allows moisture to still penetrate in various forms and eventually infiltrate the analyzer. This moisture intrusion becomes a key factor affecting the accuracy of monitoring data, potentially leading to misjudgments of catalyst conversion rates, and consequently impacting the overall production efficiency and economic benefits of the entire process. Summary of the Invention

[0005] This invention provides an embedded folded gas-liquid two-phase separator, which overcomes the shortcomings of the prior art and can effectively solve the problem that the gas-liquid separator used in the sample inlet line of existing analyzers lacks a matching condensate discharge device.

[0006] The technical solution of this utility model is achieved through the following measures: An embedded folded gas-liquid two-phase separator includes a separation tank, a baffle plate, a guide plate, and a storage tank. The gas inlet on the lower left side of the separation tank is fixedly connected to a liquid inlet pipeline, the gas outlet at the top of the separation tank is fixedly connected to a gas outlet pipeline, and the liquid outlet at the bottom of the separation tank is fixedly connected to the storage tank via a liquid outlet pipeline. Several baffle plates are arranged vertically and vertically at intervals above the liquid inlet pipeline. The baffle plates are inclined with the left side higher than the right side. A guide plate is arranged below each baffle plate in the separation tank. The guide plate is inclined with the left side lower than the right side.

[0007] The following are further optimizations and / or improvements to the above-mentioned utility model technical solution:

[0008] The separator can be equipped with three baffles spaced vertically above the corresponding inlet pipeline, with the left end of the baffle located at the bottom being below the inlet pipeline.

[0009] The aforementioned spoiler can be a faceted spoiler. The guide plate includes a first guide plate and a second guide plate. The first guide plate is inclined with the left side lower than the right side. A second guide plate with its upper end located above the right end of the first guide plate is fixedly installed. The second guide plate is inclined with the left side higher than the right side.

[0010] The above may also include a flow rectifier grille. The inlet pipeline includes a large-diameter section, a tapered section, and a small-diameter section that are fixedly installed together from left to right, and the large-diameter section is equipped with a flow rectifier grille.

[0011] The above may also include a liquid collection plate and a liquid collection manual valve. The liquid outlet pipeline includes a liquid collection section and a connecting section that are fixedly installed together from top to bottom. The liquid collection section is provided with a liquid collection plate, and the liquid collection plate is provided with several liquid collection holes. The connecting section is provided with a liquid collection manual valve.

[0012] The above may also include a gas-water separator, a chromatograph, an infrared analyzer, and a condensate drain valve. The gas inlet at the top of the gas-water separator is fixedly connected to a sample gas inlet pipe, and the gas outlet in the middle of the gas-water separator is fixedly connected to a sample gas outlet pipe. The outlet end of the sample gas outlet pipe is connected to the chromatograph and the infrared analyzer, respectively. A condensate drain pipe is fixedly connected between the liquid outlet at the bottom of the gas-water separator and the inlet end of the liquid inlet pipe, and a condensate drain valve is installed on the condensate drain pipe.

[0013] This utility model has a reasonable and compact structure and is easy to use. By using multiple sets of baffles and guide plates spaced apart inside the separator, the airflow is forced to change direction, reduce speed, and generate disturbance. By setting baffles, the laminar flow state of the airflow is disrupted, the relative motion between gas and liquid is increased, and the tiny droplets attached to the gas are more easily separated from the airflow. By setting guide plates, the airflow is guided to smoothly bypass obstacles, while droplets that have coalesced or been intercepted due to disturbance are guided to the bottom of the separator. It has the characteristics of stability, reliability and good separation effect. Attached Figure Description

Detailed Implementation

[0017] This utility model is not limited to the following embodiments, and the specific implementation method can be determined according to the technical solution of this utility model and the actual situation.

[0018] In this utility model, for ease of description, the description of the relative positions of the components is based on the appendix to the specification. Figure 1 The layout is described using a diagrammatic method, such as front, back, top, bottom, left, right, etc. The positional relationships are determined based on the layout direction of the attached diagram in the instruction manual.

[0019] The present invention will be further described below with reference to the embodiments and accompanying drawings:

[0020] Example 1: As shown in the attached document Figure 1 , 2As shown, the embedded folded gas-liquid two-phase separator includes a separation tank 1, baffles 2, guide plates, and a storage tank. The gas inlet on the lower left side of the separation tank 1 is fixedly connected to a liquid inlet pipeline, and the gas outlet at the top of the separation tank 1 is fixedly connected to an outlet pipeline 13. The liquid outlet at the bottom of the separation tank 1 is fixedly connected to the storage tank via an outlet pipeline. Several baffles 2 are arranged vertically at intervals above the inlet pipeline in the separation tank 1. The baffles 2 are inclined with the left side higher than the right side. A guide plate is provided in the separation tank 1 below each baffle 2. The guide plate is inclined with the left side lower than the right side. During operation, the separator 1 employs multiple sets of baffles 2 and guide vanes arranged at intervals, which significantly improves the gas-liquid separation effect. When condensate containing gas enters the separator 1, these staggered baffles 2 and guide vanes force the airflow to change direction, reduce speed, and generate disturbance. The baffles 2 disrupt the laminar flow state of the airflow, increasing the relative motion between gas and liquid, making it easier for tiny droplets attached to the gas to separate from the airflow. The guide vanes guide the airflow smoothly around obstacles, while directing droplets that have coalesced or been intercepted due to disturbance to the bottom of the separator 1. Therefore, by increasing the path length of the airflow and changing its flow characteristics, more opportunities and longer reaction time are provided for droplet coalescence and sedimentation, thereby more thoroughly separating liquid impurities from the gas phase, reducing liquid entrainment, and improving the purity of the discharged condensate.

[0021] The above-mentioned embedded pleated gas-liquid two-phase separator can be further optimized and / or improved according to actual needs:

[0022] Example 2: As shown in the attached document Figure 1 As shown, three baffles 2 are spaced vertically inside the separator 1, corresponding to the position above the liquid inlet line. The left end of the guide plate at the bottom position is located below the liquid inlet line. During use, the three sets of baffles 2 embedded in the separator 1 and arranged alternately with the guide plates can more effectively promote gas-liquid separation.

[0023] Example 3: As shown in the attached document Figure 1As shown, the baffle 2 is a faceted baffle 2, and the guide plate includes a first guide plate 3 and a second guide plate 4. The first guide plate 3 is inclined with its left side lower than its right side, and the second guide plate 4, with its upper end located above it, is fixedly installed at the right end of the first guide plate 3. The second guide plate 4 is also inclined with its left side higher than its right side. During use, the baffle 2 can be a known triangular faceted baffle 2. Its unique geometry causes the airflow to not only change direction when it passes through, but also produces a centrifugal separation-like effect. The airflow turns along the hypotenuse of the triangular facet, and the internal flow velocity and pressure distribution change. The weak multi-directional centrifugal force field generated by this change can more effectively throw the tiny droplets following the airflow out of the mainstream. In addition, compared with the planar baffle 2, the triangular faceted baffle 2 provides a stronger turbulence effect, can more thoroughly disrupt the stability of the gas-liquid interface, and promotes the easier aggregation of droplets, which are then guided to the bottom of the separation tank 1 by the guide plate below. Therefore, this structure not only enhances the turbulence of the airflow and the efficiency of droplet separation, but also, due to its compact structure, allows for the arrangement of more effective turbulence units within the limited space inside the tank, thereby improving the overall processing capacity and separation accuracy of the separation tank 1.

[0024] Example 4: As shown in the appendix Figure 1 As shown, it also includes a flow-rectifying grid 5. The inlet pipeline consists of a large-diameter section 6, a tapered section 7, and a small-diameter section 8, which are fixedly installed together from left to right. The flow-rectifying grid 5 is installed inside the large-diameter section 6. During use, the purpose of the flow-rectifying grid 5 inside the large-diameter section 6 is to improve the fluid state and create a pre-separation zone in this section. Untreated incoming flow often has problems such as eddies, turbulence, or uneven velocity distribution. The flow-rectifying grid 5, through its grid structure, can break up large-scale vortices, forcing the fluid to flow forward more uniformly and smoothly. This rectification effect makes the large-diameter section 6 not only serve as a connection and transition but also form a preliminary pre-separation section. In a relatively stable and low-velocity flow field, denser liquid particles are more likely to settle and separate from the gas phase under the action of gravity, especially those larger droplets. Subsequently, the mixed fluid enters the tapered section 7 and the small-diameter section 8. The small-diameter section 8 uses a gradually narrowing flow channel to accelerate the mixed fluid, and utilizes acceleration and centrifugal effect to further separate smaller droplets, thereby improving the primary separation efficiency of the entire inlet pipeline section.

[0025] Example 5: As shown in the attached document Figure 1As shown, it also includes a liquid collecting plate 9 and a liquid collecting manual valve 10. The liquid outlet pipeline includes a liquid collecting section 11 and a connecting section 12, which are fixedly installed together from top to bottom. The liquid collecting section 11 is equipped with a liquid collecting plate 9, which has several liquid collecting holes. The connecting section 12 is equipped with a liquid collecting manual valve 10. During use, the liquid collecting plate 9 and the liquid collecting manual valve 10 in the liquid outlet pipeline can significantly improve the efficiency of liquid collection and discharge control. The liquid collecting plate 9 and the several liquid collecting holes opened on it, together with the liquid collecting section 11, form a porous flow collection cavity, which can effectively collect liquids from different directions or dispersed areas. When the separated liquid enters the collection section 11, the collection plate 9 prevents excessive entrainment of the gas phase, forcing the liquid to flow through the small holes into the lower collection chamber, thus achieving effective gas-liquid separation and initial liquid collection. The collection hand valve 10, located on the connecting section 12, provides precise control over the entire discharge process. Operators can manually adjust the valve opening to control the liquid discharge rate and timing, avoiding system pressure fluctuations caused by excessively rapid liquid discharge and allowing for pauses in discharge for inspection or handling when necessary. Therefore, this combination of the collection plate 9 and the collection hand valve 10 not only enhances the reliability of liquid collection but also makes liquid discharge more controllable, facilitating maintenance and management.

[0026] Example 6: As shown in the appendix Figure 2 As shown, the system also includes a gas-liquid separator 14, a chromatograph 15, an infrared analyzer 16, and a condensate drain valve 17. The gas inlet at the top of the gas-liquid separator 14 is fixedly connected to a sample gas inlet pipe 18, and the gas outlet in the middle of the gas-liquid separator 14 is fixedly connected to a sample gas outlet pipe 19. The outlet end of the sample gas outlet pipe 19 is connected to both the chromatograph 15 and the infrared analyzer 16. A condensate drain pipe 20 is fixedly connected between the liquid outlet at the bottom of the gas-liquid separator 14 and the inlet end of the liquid inlet pipe, and a condensate drain valve 17 is installed on the condensate drain pipe 20. In use, by applying the embedded faceted gas-liquid two-phase separator to the existing process, it can effectively solve the problem that the gas-liquid separator 14 used on the sample inlet line of the existing analyzer lacks a matching condensate drain device.

[0027] The above technical features constitute the preferred embodiment of this utility model, which has strong adaptability and the best implementation effect. Unnecessary technical features can be reduced according to actual needs to meet the needs of different situations.
