Description

Technical Field

[0001] This utility model relates to the field of steam-water separation technology, specifically a steam-water separator. Background Technology

[0002] In many fields such as industrial production, energy development, and HVAC, the treatment of liquid-containing gas streams is a key link in ensuring the efficient operation of equipment and the safe and stable operation of systems. For example, in steam power systems, steam is prone to condensation into droplets during transmission due to temperature fluctuations and pressure changes; in natural gas extraction and transportation, natural gas often carries formation water and condensate oil; in compressed air systems, water vapor in the air is converted into liquid water during compression. If these droplets enter subsequent equipment (such as steam turbines, compressors, precision instruments, etc.) with the gas stream, they will not only reduce the heat exchange efficiency of the equipment and increase energy consumption, but may also cause problems such as pipeline corrosion and equipment erosion and wear. In severe cases, they may even lead to equipment failure and shutdown, resulting in economic losses. Therefore, gas-liquid separation, as a core technology for removing liquid impurities from gas streams, is directly related to the operating quality and service life of the entire industrial system, and has become an indispensable key process in the industrial field.

[0003] In existing technologies, gas-liquid separators have taken on various structural forms. Among them, cyclone separators are widely used due to their relatively simple structure and large processing capacity. These separators typically consist of a cylindrical or conical separation shell with a tangential air inlet on the side wall, an exhaust port at the top or middle, and a drainage structure at the bottom. The working process is roughly as follows: the liquid-containing gas enters the separation shell through the tangential air inlet, forming a high-speed rotating spiral airflow inside the shell. Utilizing the density difference between the gas and liquid phases, the denser liquid droplets are thrown towards the shell wall under centrifugal force. After impacting the wall, the droplets lose kinetic energy and settle to the bottom of the shell under gravity, eventually being discharged through the drainage structure. The purified gas flows upward along the spiral trajectory and exits the equipment through the exhaust port, thus achieving the purpose of gas-liquid separation. Some separators also have fixed guide vanes or baffles added inside to help optimize the flow field and enhance the separation effect.

[0004] However, existing steam-water separators still have some problems in practical applications. The separation efficiency is significantly affected by the airflow velocity. When the inlet airflow velocity is too high, a turbulent flow field is easily formed inside the shell. The droplets that have settled to the bottom may be re-rolled up by the high-speed airflow, resulting in a decrease in the separation effect. When the flow velocity is too low, the centrifugal force is insufficient, making it difficult to effectively separate the tiny droplets. The range of applicable working conditions is narrow. The internal flow guiding structure of traditional separators is mostly fixed and cannot adjust the angle or position according to the dynamic changes of airflow parameters. It is difficult to always maintain the optimal flow field state and has poor adaptability to airflows with different flow rates and liquid contents. Therefore, we propose a steam-water separator. Utility Model Content

[0005] The technical problem to be solved by this utility model is to overcome the existing defects and provide a steam-water separator that can adaptively adjust the guide angle to adapt to different working conditions, prevent the re-rolling of settled droplets, and effectively solve the problems in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a steam-water separator, comprising a separation shell, a drain pipe at the lower end of the separation shell, and a separation mechanism;

[0007] Separation mechanism: It includes an inverted cone cavity, hollow guide vanes, a cross plate and an exhaust pipe. The inverted cone cavity is located at the upper part of the inner side of the separation shell. The hollow guide vanes are rotatably connected to the middle of the inner wall of the separation shell. The exhaust pipe is fixedly connected to the exhaust hole at the middle of the upper side wall of the separation shell. The lower end of the exhaust pipe is located at the middle gap of the hollow guide vanes that are circumferentially distributed at equal angles. The cross plate is fixedly connected to the lower part of the inner side of the separation shell.

[0008] It also includes an air intake pipe, which is fixedly connected to the air inlet at the upper end of the separator shell. The central axis of the air intake pipe is tangent to the inner arc surface of the inverted cone cavity. It can adaptively adjust the guide angle to adapt to different working conditions, prevent the re-rolling of settled droplets, and achieve high separation efficiency.

[0009] Furthermore, the separation mechanism also includes a counterweight and a limiting post. The counterweight is fixedly connected to the lower end of the hollow guide vane, and the limiting post is fixedly connected to the middle of the inner wall of the separation shell. The limiting post is installed in conjunction with the upper end of the radially adjacent hollow guide vane. The counterweight and the limiting post cooperate to allow the hollow guide vane to dynamically adjust its angle according to the airflow speed.

[0010] Furthermore, a connecting pipe is installed at the lower end of the separating shell, and the connecting pipe is connected to the separating shell. A contact switch is provided on the top wall of the right end of the connecting pipe, and the input end of the contact switch is electrically connected to an external power supply for stable control.

[0011] Furthermore, an electric drain valve is connected in series in the middle of the drainage pipe. The input end of the electric drain valve is electrically connected to the output end of a contact switch for drainage.

[0012] Furthermore, a sliding frame is fixedly connected to the upper side of the inner arc surface at the right end of the connecting pipe, and a sliding rod is slidably connected inside the sliding frame. The upper end of the sliding rod is used in conjunction with a contact switch, and a floating ball is fixedly connected to the lower end of the sliding rod. The sliding frame, the sliding rod, and the floating ball constitute a mechanically linked liquid level sensing structure. The floating ball moves the sliding rod along the sliding frame as the liquid level rises and falls, accurately realizing the contact or disengagement of the sliding rod with the contact switch, providing a reliable liquid level triggering logic for the automatic control of the electric drain valve.

[0013] Furthermore, a check valve is connected in series in the middle of the air intake pipe to ensure stable unidirectional airflow.

[0014] Furthermore, an observation window is provided at the lower end of the outer arc wall of the separation shell, which facilitates operators to monitor the equipment operation in real time.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows: This steam-water separator has the following advantages:

[0016] 1. The separation mechanism, through the inverted conical cavity and the tangentially set air inlet pipe, makes the liquid-containing airflow form a high-speed rotating spiral flow field. The liquid droplets are initially separated by centrifugal force and inertial force. The hollow guide vanes distributed at equal angles around the circumference can adaptively adjust their angles according to the airflow velocity under the synergistic action of the counterweight and the limiting column. It can stabilize the flow field by reasonable deflection when the flow velocity increases, and can reset to maintain the guiding effect when the flow velocity decreases, adapting to different working conditions.

[0017] 2. The cross plate can effectively block the formation of vortices in the lower airflow, preventing settled droplets from being re-entrained into the airflow, further ensuring separation effectiveness and significantly improving separation efficiency and effect. Attached Figure Description

Detailed Implementation

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Please see Figure 1-5 This embodiment provides a technical solution: a steam-water separator, including a separation shell 1, an observation window 11 at the lower end of the outer arc wall of the separation shell 1, the observation window 11 at the lower end of the outer arc wall of the separation shell 1 allows the operator to intuitively observe the changes in the internal liquid level and the separation status, and promptly detect abnormal equipment operation; the lower end of the separation shell 1 is provided with a drain pipe 12.

[0026] A connecting pipe 3 is installed at the lower end of the separating shell 1, and the connecting pipe 3 is connected to the separating shell 1. A contact switch 7 is provided on the top wall of the right end of the connecting pipe 3. The input end of the contact switch 7 is electrically connected to an external power source. An electric drain valve 8 is connected in series in the middle of the drain pipe 12. The input end of the electric drain valve 8 is electrically connected to the output end of the contact switch 7. A sliding frame 4 is fixedly connected to the upper side of the inner arc surface of the right end of the connecting pipe 3. A sliding rod 5 is slidably connected inside the sliding frame 4. The upper end of the sliding rod 5 is used in conjunction with the contact switch 7. A floating ball 6 is fixedly connected to the lower end of the sliding rod 5. At the lower end of the separating shell 1, the separating... The separated liquid gradually accumulates and is connected to the external liquid level sensing structure through the connecting pipe 3. As the liquid level rises, the floating ball 6 in the connecting pipe 3 floats upward under the action of buoyancy, which drives the slide rod 5 to slide upward along the sliding frame 4. When the upper end of the slide rod 5 contacts the contact switch 7 on the top wall of the right end of the connecting pipe 3, the contact switch 7 triggers the electric drain valve 8 to open, and the accumulated liquid is discharged through the drain pipe 12. When the liquid level drops, the floating ball 6 sinks down, the slide rod 5 disengages from the contact switch 7, and the electric drain valve 8 closes, realizing the automatic discharge of liquid. It also includes a separation mechanism 2.

[0027] Separation mechanism 2 includes an inverted cone cavity 21, hollow guide vanes 22, a cross plate 25, and an exhaust pipe 26. The inverted cone cavity 21 is located at the upper part of the interior of the separation shell 1. The hollow guide vanes 22 are rotatably connected to the middle of the inner wall of the separation shell 1. The exhaust pipe 26 is fixedly connected to the exhaust hole at the middle of the upper side wall of the separation shell 1. The lower end of the exhaust pipe 26 is located at the middle gap of the hollow guide vanes 22, which are distributed at equal angles around the circumference. (The hollow guide vanes 22 are hollow guide vanes designed to reduce their weight and facilitate rotation around the upper axis of the hollow guide vanes 22 when subjected to airflow. The hollow guide vanes 22 are distributed at equal angles around the central axis of the separation shell 1.) The cross plate 25 is fixedly connected to the lower part of the interior of the separation shell 1. After the airflow enters the separation shell 1, the droplets in the airflow are thrown towards the inner wall of the separation shell 1 due to inertia and centrifugal force. After the droplets hit the wall, they lose kinetic energy and are then subjected to gravity. The airflow flows downward along the lower edge of the wall and enters the lower region of the separation shell 1. The cross plate 25 is fixed inside the lower end of the separation shell 1, which can effectively block the airflow from forming a vortex and prevent the settled droplets from being re-entrained into the airflow, thus further ensuring the separation effect of the droplets. The hollow guide plate 22 in the separation mechanism 2 is installed in the middle of the inner wall of the separation shell 1 by a rotatable connection. The counterweight 23 at the lower end of its interior can adjust the angle of the hollow guide plate 22 when the airflow velocity changes: when the flow velocity increases, the thrust of the airflow on the hollow guide plate 22 increases, causing it to deflect around the rotation axis. The limiting post 24 can limit the maximum deflection angle of the hollow guide plate 22, avoiding excessive rotation that affects the stability of the flow field. When the flow velocity decreases, the gravity of the counterweight 23 causes the hollow guide plate 22 to return to its original position, always maintaining a reasonable guidance for the airflow and improving the separation efficiency under different working conditions. The gas is finally discharged from the equipment through the exhaust pipe 26 located in the central region, which facilitates the separation of steam and water.

[0028] The separation mechanism 2 also includes a counterweight 23 and a limiting post 24. The counterweight 23 is fixedly connected to the lower end of the hollow guide vane 22, and the limiting post 24 is fixedly connected to the middle of the inner wall of the separation shell 1. The limiting post 24 is installed in conjunction with the upper end of the radially adjacent hollow guide vane 22.

[0029] The system also includes an air inlet pipe 9, which is fixedly connected to the air inlet at the upper end of the separation shell 1. The central axis of the air inlet pipe 9 is tangent to the inner arc surface of the inverted cone cavity 21. The liquid-containing gas flow first enters the equipment through the air inlet pipe 9. Since the central axis of the air inlet pipe 9 is tangent to the inner arc surface of the inverted cone cavity 21, the air flow will form a high-speed rotating spiral flow field along the inner wall of the inverted cone cavity 21. Under the guidance of the inverted cone cavity 21, the spiral air flow gradually diffuses downward and enters the middle area of ​​the separation shell 1. A check valve 10 is connected in series in the middle of the air inlet pipe 9. The check valve 10 connected in series in the middle of the air inlet pipe 9 can prevent the discharged gas or liquid from flowing back to the air inlet end, ensuring a stable unidirectional flow of air.

[0030] The working principle of the gas-water separator provided by this utility model is as follows: The liquid-containing gas flow first enters the equipment through the air inlet pipe 9. Since the central axis of the air inlet pipe 9 is tangent to the inner arc surface of the inverted cone cavity 21, the gas flow forms a high-speed rotating spiral flow field along the inner wall of the inverted cone cavity 21. Under the guidance of the inverted cone cavity 21, the spiral gas flow gradually diffuses downward and enters the middle region of the separation shell 1. During this process, the liquid droplets in the gas flow are thrown towards the inner wall of the separation shell 1 due to inertia and centrifugal force. After the droplets hit the wall, they lose kinetic energy and flow downward along the wall under the action of gravity. The cross plate 25 is fixed inside the lower part of the separation shell 1, effectively blocking the airflow from forming a vortex and preventing the settled droplets from being re-entrained into the airflow, thus further ensuring the separation effect of the droplets. The hollow guide plate 22 in the separation mechanism 2 is rotatably connected and installed in the middle of the inner wall of the separation shell 1. The counterweight 23 at the lower end of its interior can adjust the angle of the hollow guide plate 22 when the airflow velocity changes: when the flow velocity increases, the thrust of the airflow on the hollow guide plate 22 increases, causing it to deflect around the rotation axis. The limiting post 24 can limit the maximum rotation of the hollow guide plate 22. The deflection angle is adjusted to avoid excessive rotation affecting flow field stability. When the flow velocity decreases, the gravity of the counterweight 23 causes the hollow guide vane 22 to reset, maintaining proper airflow guidance and improving separation efficiency under different operating conditions. The gas is finally discharged from the equipment through the exhaust pipe 26 located in the central area. At the lower end of the separation shell 1, the separated liquid gradually accumulates and is connected to the external liquid level sensing structure through the connecting pipe 3. As the liquid level rises, the floating ball 6 inside the connecting pipe 3 floats upward under buoyancy, driving the slide rod 5 to slide upward along the sliding frame 4. When the upper end of the slide rod 5 contacts the... When the contact switch 7 on the top wall of the right end of the connecting pipe 3 is activated, the contact switch 7 triggers the electric drain valve 8 to open, and the accumulated liquid is discharged through the drain pipe 12. When the liquid level drops, the float ball 6 sinks accordingly, the slide rod 5 disengages from the contact switch 7, and the electric drain valve 8 closes, realizing the automatic discharge of liquid. The check valve 10 connected in series in the middle of the air inlet pipe 9 can prevent the discharged gas or liquid from flowing back to the air inlet end, ensuring a stable unidirectional airflow. The observation window 11 at the lower end of the outer arc wall of the separation shell 1 allows the operator to visually observe the changes in the internal liquid level and the separation status, and promptly detect any abnormalities in the equipment operation.

[0031] It is worth noting that the electric drain valve 8 disclosed in the above embodiments can be from the 4WE6 series, and the contact switch 7 is provided with a control button corresponding to the electric drain valve 8 and used to control its switching.

[0032] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the content of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
