Description

Technical Field

[0001] This utility model relates to the field of steam-water separator technology, and in particular to a steam-water separator with water level control. Background Technology

[0002] A gas-liquid separator is a device that uses gravity or centrifugal force to separate gas and liquid. It is mainly used to improve the dryness of gas or steam, remove liquid moisture, and ensure the safe operation of downstream equipment. It is commonly used in the power industry, petrochemical industry, and other fields.

[0003] However, most gas-water separators on the market cannot detect and adjust the liquid level in the separator in real time during operation. When the liquid level in the separator is disrupted, it is difficult to restore it in time, which affects work efficiency.

[0004] Therefore, a steam-water separator with water level control that can self-regulate the liquid level is proposed to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to address the aforementioned shortcomings by providing a steam-water separator with water level control, enabling self-regulation of the liquid level.

[0006] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: a steam-water separator with water level control, comprising;

[0007] The separation component includes a cone-shaped separation chamber with an air inlet tangential to the inner wall on its side wall. The air inlet is tangentially arranged to drive the airflow in a spiral flow. An air outlet is provided at the top, and a water outlet with a first flow channel is provided at the bottom. The first flow channel is used to guide the fluid medium out of the chamber.

[0008] The detection component includes a sealed block that is vertically slidably disposed in the outlet, with a through hole inside that is misaligned with the first flow channel. The separation chamber is provided with a float that can float on the fluid medium. The float is connected to the sealed block by a connecting rod so that the sealed block can slide vertically with the change of liquid level. The opening and closing of the outlet is controlled by the relative position of the through hole and the first flow channel.

[0009] Furthermore, the separation component also includes an air supply pipe vertically disposed inside the separation chamber and connected to the air outlet, wherein multiple heat exchange plates are spirally distributed inside the air supply pipe to guide the airflow spirally and exchange heat with it.

[0010] Furthermore, each of the heat exchange plates has a chamber, and the air duct has a second flow channel for conveying the cooling medium. The air inlet of the second flow channel is connected to the top of each of the chambers, and the air outlet is connected to the bottom of each of the chambers.

[0011] Furthermore, the connecting rod is a telescopic rod used to adjust the height of the float; the connecting rod is provided with a limiting component to constrain the movement of its telescopic end.

[0012] Furthermore, the limiting component includes a plurality of limiting holes vertically distributed on the fixed end of the connecting rod, and a positioning hole corresponding to the limiting holes is provided on the telescopic end; a limiting pin is detachably inserted into the positioning hole.

[0013] Furthermore, a cover is detachably provided on one side of the separation chamber, and the cover is provided with an observation window for observing the liquid level of the fluid medium.

[0014] The beneficial effects of this utility model are reflected in:

[0015] This invention, through the cooperation between the separation chamber and the detection component, separates the gas-liquid mixture in the separation chamber. The separation chamber then separates the gas and liquid through centrifugal force. The separated gas flows out of the separation chamber, while the liquid medium is stored inside. When the liquid level is higher than a predetermined value, the liquid medium causes a float to rise, which in turn causes a sealing block to move vertically upward until the first flow channel connects with the through hole, thereby discharging the liquid medium from the separation chamber. This continues until the liquid level drops to the predetermined height. At this point, the first flow channel and the through hole are misaligned again, and the outlet is closed. This allows for real-time maintenance of the liquid level in the separation chamber, ensuring operational efficiency. Attached Figure Description

[0022] 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 a part of the embodiments of the present utility model, and not all of them. Unless otherwise specified, the embodiments and features in the embodiments of this application can be combined with each other. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present utility model.

[0023] Please see Figure 1-4 This utility model discloses a steam-water separator with water level control, comprising:

[0024] The separation component 1 includes a cone-shaped separation chamber 11 with an air inlet 111 tangential to the inner wall on its side wall. The air inlet 111 is tangentially arranged to drive the airflow in a spiral flow. The top has an air outlet 112 and the bottom has a water outlet 113 with a first flow channel 14 cut out. The first flow channel 14 is used to guide the fluid medium to be discharged.

[0025] The detection component 2 includes a sealing block 21 that is vertically slidably disposed in the outlet 113. The sealing block 21 has a through hole 22 that is misaligned with the first flow channel 14. The separation chamber 11 is provided with a float 23 that can float on the fluid medium. The float 23 is connected to the sealing block 21 through a connecting rod 24 so as to drive the sealing block 21 to slide vertically with the change of liquid level. The opening and closing of the outlet 113 is controlled by the relative position of the through hole 22 and the first flow channel 14.

[0026] In practice, when the gas-liquid mixture enters the separation chamber through the inlet 111, the mixture, constrained by the inner wall of the separation chamber 11, changes from linear motion to circular motion, forming an external swirling flow. This causes the airflow to drive the liquid medium in a spiral flow within the separation chamber 11. Under centrifugal force, the liquid medium is thrown onto the inner wall of the separation chamber 11 and accumulates at the outlet 113 under gravity. The airflow, after spiraling, is then blown out of the separation chamber 11 from the outlet 112, leaving the liquid medium within the separation chamber 11. When the liquid level of the liquid medium is higher than the predetermined value, the liquid medium causes the float 23 to float upward. The float 23 drives the sealing block 21 to move vertically upward through the connecting rod 24 until the first flow channel 14 and the through hole 22 are connected. At this time, the liquid medium flows out of the separation chamber 11 through the first flow channel 14 and the through hole 22 in sequence. The liquid level of the liquid medium drops and causes the float 23 to move downward until the first flow channel 14 and the through hole 22 are misaligned again. The liquid medium no longer flows out of the separation chamber 11, and the liquid level returns to the predetermined value.

[0027] In this invention, through the cooperation between the separation chamber 11 and the detection component 2, after the gas-liquid mixture enters the separation chamber 11, the separation chamber 11 separates the gas and liquid through centrifugal force. The separated gas flows out of the separation chamber 11, while the liquid medium is stored inside the separation chamber 11. When the liquid level of the liquid medium is higher than a predetermined value, the liquid medium drives the float 23 to float upward. The float 23 drives the sealing block 21 to move vertically upward until the first flow channel 14 connects with the through hole 22, thereby discharging the liquid medium out of the separation chamber 11. When the liquid level of the liquid medium drops to the predetermined height, the first flow channel 14 and the through hole 22 are misaligned again, and the outlet 113 is closed. This allows the liquid level of the liquid medium in the separation chamber 11 to be maintained in real time, ensuring working efficiency.

[0028] It should be noted that the structure and function of the separation chamber 11 can refer to the cyclone separator in the prior art, and the structure and function of the cyclone separator are common knowledge to those skilled in the art, so they will not be described in detail here.

[0029] It should be noted that multiple first flow channels 14 can be provided at the outlet 113 of the separation chamber 11, and through holes 22 corresponding to each first flow channel 14 are provided on its sealing block 21, thereby improving the efficiency of liquid medium flowing out of the separation chamber 11.

[0030] In one embodiment, the separation component 1 further includes an air supply pipe 12 vertically disposed in the separation chamber 11 and connected to the air outlet 112. The diameter of the air supply pipe 12 is smaller than the inner cavity size of the separation chamber 11. Multiple heat exchange plates 13 are spirally distributed inside the air supply pipe 12. Each heat exchange plate 13 is used to guide the airflow spirally and exchange heat with it.

[0031] With this design, when the high-temperature gas-liquid mixture enters the separation chamber 11, the gas flow after gas-liquid separation in the separation chamber 11 rises and flows into the air duct 12. Due to the principle of fluid continuity, the flow velocity of the gas flow increases as it enters the air duct 12, and it is spirally transported again under the guidance of each heat exchange plate 13. This allows excess moisture in the gas flow to fully exchange heat with the heat exchange plates 13, resulting in gas condensation. The condensate on the heat exchange plates 13 falls into the separation chamber 11 under the action of gravity, thereby recovering excess moisture in the gas and further improving the efficiency of gas-liquid separation.

[0032] Preferably, the heat exchange plate 13 can be a condenser plate as used in the prior art.

[0033] In one embodiment, each heat exchange plate 13 has a chamber 131, and the air duct 12 also has a second flow channel 121 for conveying cooling medium. The air inlet of the second flow channel 121 is connected to the top of each chamber 131, and its air outlet is connected to the bottom of each chamber 131. The second flow channel 121 is used to convey cooling medium into each heat exchange plate 13.

[0034] With this design, when each heat exchange plate 13 exchanges heat with the airflow, the external cooling component (not shown in the figure) delivers cooling medium into the air inlet of the second flow channel 121. The cooling medium enters each heat exchange plate 13 in the second flow channel 121 to exchange heat with it, thus avoiding overheating of the heat exchange plate 13 and affecting the heat exchange efficiency with the airflow. After heat exchange, the cooling medium flows out from the bottom of each chamber 131 and leaves the air duct 12 from the air outlet of the second flow channel 121.

[0035] It should be noted that cooling water can be used as the cooling medium.

[0036] In one embodiment, the connecting rod 24 is a telescopic rod, and the float 23 is disposed at the top end of the telescopic rod of the connecting rod 24. The connecting rod 24 is used to adjust the height of the float 23. The connecting rod 24 is also provided with a limiting component to constrain the movement of the telescopic end of the connecting rod 24.

[0037] With this design, when it is necessary to adjust the liquid level of the liquid medium in the separation chamber 11, the operator can adjust the extension length of the telescopic end of the connecting rod 24 until the height of the float 23 corresponds to the predetermined liquid level. Then, the movement of the telescopic end of the connecting rod 24 is constrained by the limiting component to prevent the height of the float 23 from changing unexpectedly.

[0038] In one embodiment, the limiting component includes a plurality of limiting holes 241 vertically distributed on the fixed end of the connecting rod 24, and a positioning hole 242 corresponding to the limiting holes 241 is provided on its telescopic end; a limiting pin 25 is detachably inserted into the positioning hole 242.

[0039] With this design, when it is necessary to adjust the setting height of the float 23, the operator will separate the limit pin 25 from the connecting rod 24 and adjust the extension of the telescopic end of the connecting rod 24 until the positioning hole 242 corresponds to the corresponding limit hole 241. At this time, the limit pin 25 will be inserted into the positioning hole 242 and the corresponding limit hole 241.

[0040] In one embodiment, the outlet 113 is provided with a drain tank (not shown in the figure) for discharging liquid medium;

[0041] The separation chamber 11 has a detachable cover 3 on one side, and the cover 3 has an observation window 31 for observing the liquid level of the fluid medium.

[0042] With this design, when the length of the connecting rod 24 needs to be adjusted, the operator first drains the liquid medium through the drain tank and then adjusts the connecting rod 24 by opening the hatch cover 3. When the separation chamber 11 is in operation, the operator can conveniently and quickly monitor the liquid level of the liquid medium in the separation chamber 11 through the observation window 31.

[0043] It should be noted that the hatch cover 3 and the separation chamber 11 can be connected by bolts, and a sealing ring is provided between the hatch cover 3 and the separation chamber 11 to ensure the airtightness of the separation chamber 11.

[0044] It should be noted that if the embodiments of this utility model involve directional indicators (such as up, down, left, right, front, back, etc.), the directional indicators are only used to explain the relative positional relationship and movement of the components in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indicators will also change accordingly.

[0045] Furthermore, if the embodiments of this utility model involve descriptions such as "first" or "second," these descriptions are for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of indicated technical features. Therefore, features defined with "first" or "second" may explicitly or implicitly include at least one of those features. Additionally, the technical solutions of the various embodiments can be combined with each other, but this must be based on the ability of those skilled in the art to implement them. If the combination of technical solutions is contradictory or impossible to implement, it should be considered that such a combination of technical solutions does not exist and is not within the scope of protection claimed by this utility model.

[0046] Additionally, "multiple" refers to two or more.

[0047] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
