Description

Technical Field

[0001] This invention relates to the field of chemical dosing technology for cooling water in power plants, and more specifically, to an automatic online monitoring device for circulating water. Background Technology

[0002] Power plant circulating cooling water requires chemical treatment to address three key issues in the cooling water system: corrosion, scaling, and microbial growth. This ensures safe and stable equipment operation, improves cooling efficiency, and extends the system's lifespan. However, the continuous injection method used in some technologies limits the diffusion rate of the chemicals after they enter the main pipeline, leading to excessively large local concentration differences and affecting the chemicals' effectiveness.

[0003] Referring to the relevant technical document CN223213858U, an automatic monitoring and dosing device for circulating water quality in a computer room is disclosed. When adding chemicals to the central connecting pipe, the control valve of the dosing pipe for the corresponding chemical is opened, and the booster pump in the storage tank is turned on at the same time, so that the chemical in the storage tank can enter the dosing pipe. Since the circulating water in the computer room can drive the blades to rotate when passing through the central connecting pipe, the rotating rod drives the rotating disk to rotate, so that the docking hole on the rotating disk and the guide hole on the fixed disk are continuously connected and dynamically switched (a flow channel is formed when the holes are aligned and closed when they are misaligned). This realizes the intermittent flow of the chemical into the central connecting pipe and avoids the problem of excessively high local concentration near the dosing point and insufficient concentration far away that may be caused by continuous dosing. The rotating blades can also mix the added chemical with the water, which greatly improves the treatment effect of the chemical on the water quality.

[0004] However, if some agents (such as solid corrosion inhibitors and high-viscosity biocides) are not dissolved and diluted to a suitable concentration before being added directly as high-concentration stock solutions, the large difference in density and viscosity between the agent solution and the cooling water will make it difficult to disperse quickly, forming "agent clumps" that are suspended or deposited locally. After entering the main pipe, the "agent clumps" will quickly separate from the rotating blades, failing to effectively disperse them and affecting the effectiveness of the agent. Summary of the Invention

[0005] The present invention aims to at least solve one of the technical problems existing in the prior art. Therefore, one object of the present invention is to provide an automatic online monitoring device for circulating water, which can improve the dissolution efficiency and uniformity of reagents and ensure the accuracy of monitoring.

When the threaded sleeve moves along the length direction of the reciprocating screw, the wedge is adapted to abut against the second fixed shaft to drive the second fixed shaft to move upward, so that the first through hole and the second through hole coincide.

They are used only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention.

[0023] The automatic online monitoring device for circulating water according to an embodiment of the present invention is described below with reference to the accompanying drawings.

[0024] Reference Figures 1-3 As shown, the automatic online monitoring device 100 for circulating water according to an embodiment of the present invention may include: a main pipe 10, a buffer pipe 20, and a stirring mechanism 30.

[0025] Specifically, the main pipe 10 can transmit circulating water, the buffer pipe 20 is located on one side of the main pipe 10, and the buffer pipe 20 has a dissolving chamber 21, a dosing port and a discharging port 22. The dosing port and the discharging port 22 are connected to the dissolving chamber 21, and the discharging port 22 is connected to the main pipe 10. The stirring mechanism 30 is located in the dissolving chamber 21.

[0026] Therefore, the reagent can enter the dissolving chamber 21 through the dosing port to dissolve the reagent. After dissolving through the buffer tube 20, the reagent enters the main pipeline 10 through the outlet 22 to mix with the circulating water in the main pipeline 10. The mixing of the reagent and the circulating water is enhanced by the stirring mechanism 30, which solves the problem of uneven mixing caused by directly adding the reagent to the main pipeline 10, thus ensuring the accuracy of monitoring. At the same time, the entire process is pre-treated by stirring in the buffer tube 20, which improves the dissolution efficiency and uniformity of the reagent, laying the foundation for the accuracy of subsequent monitoring.

[0027] For example, when the automatic online monitoring device 100 for circulating water is working, an appropriate amount of liquid to be mixed (such as circulating water or solvent) is added to the dissolving chamber 21 in advance. Then, the reagent is added to the dissolving chamber 21 through the dosing port. The stirring mechanism 30 is started to stir the reagent and the liquid to be mixed in the dissolving chamber 21, so as to promote the reagent to dissolve fully. The uniformly dissolved reagent mixture flows into the main pipeline 10 through the dosing port 22 and naturally mixes with the circulating water in the main pipeline 10. This avoids the undissolved reagent particles affecting the composition of the circulating water and ensures that the subsequent online monitoring device can accurately obtain the real index data of the circulating water.

[0028] The circulating water automatic online monitoring device 100 according to an embodiment of the present invention is used to transmit circulating water through a main pipeline 10. The buffer pipe 20 has a dissolving chamber 21 and a dosing port and a dispensing port 22 connected to the dissolving chamber 21. The dispensing port 22 is connected to the main pipeline 10. The stirring mechanism 30 is disposed in the dissolving chamber 21, so that the agent can be dissolved through the buffer pipe 20 and then enter the main pipeline 10 from the dispensing port 22 to mix with the circulating water in the main pipeline 10. The stirring mechanism 30 enhances the mixing of the agent and the circulating water, which is beneficial to improving the dissolution efficiency and uniformity of the agent. This solves the problem that the agent is easily mixed unevenly when directly added to the main pipeline 10, which affects the accuracy of monitoring, and ensures the accuracy of monitoring.

[0029] In some embodiments of the present invention, such as Figures 4-6 As shown, the medicine outlet 22 is connected to the main pipeline 10 through the connecting pipe 23, which enables the connection between the buffer pipe 20 and the main pipeline 10, and the structure is simple. An adjustment mechanism 40 is provided at the end of the connecting pipe 23 near the buffer pipe 20. The adjustment mechanism 40 includes a fixed valve plate 41, a movable valve plate 42, and an opening and closing assembly 43. The fixed valve plate 41 is fixed at the medicine outlet 22 and has a first through hole. The movable valve plate 42 is located on the side of the fixed valve plate 41 near the dissolving chamber 21 in the thickness direction, and the movable valve plate 42 can rotate relative to the fixed valve plate 41. The movable valve plate 42 has a second through hole 421. The opening and closing assembly 43 can control the rotation of the movable valve plate 42. When the first through hole and the second through hole 421 coincide, the buffer pipe 20 and the main pipeline 10 are connected.

[0030] When the automatic online monitoring device 100 for circulating water is in operation, the reagent is added to the buffer tube 20, and the stirring mechanism 30 is activated to promote its full dissolution. When it is necessary to transport the reagent mixture in the buffer tube 20, the opening and closing component 43 drives the movable valve plate 42 to rotate. When the second through hole 421 coincides with the first through hole, a liquid flow channel is formed, that is, the buffer tube 20 and the main pipeline 10 are connected, and the reagent mixture flows into the main pipeline 10 through the connecting pipe 23. Thus, the connection between the main pipeline 10 and the buffer tube 20 can be controlled by the adjusting mechanism 40, which facilitates precise control of the flow and ensures that the reagent enters the main pipeline 10 after being fully dissolved. It also allows the reagent mixture to flow in as needed, which facilitates flexible flow adjustment and ensures the accuracy of monitoring. This solves the problem of not being able to adjust the flow as needed. At the same time, the adjusting mechanism 40 has a simple structure, is easy to manufacture, and helps to reduce production costs.

[0031] According to some embodiments of the present invention, such as Figure 3 , Figures 5-9 As shown, the stirring mechanism 30 includes a mounting plate 31, stirring blades 32, and a rotary drive assembly 33. The mounting plate 31 is disposed in the dissolving chamber 21, the stirring blades 32 are rotatably disposed on the mounting plate 31, and the rotary drive assembly 33 is disposed on the mounting plate 31. The mounting plate 31 can limit the movement of the stirring blades 32 and the rotary drive assembly 33. The rotary drive assembly 33 can drive the stirring blades 32 to rotate, so that the stirring blades 32 can quickly stir and mix the agent and the liquid to be mixed in the dissolving chamber 21, effectively promoting the full dissolution of the agent, solving the technical problems of low agent dissolution efficiency and uneven mixing. Moreover, the stirring mechanism 30 has a simple structure and is easy to manufacture.

[0032] In some embodiments of the present invention, such as Figure 3 , Figure 9 and Figure 10 As shown, the stirring mechanism 30 also includes a reciprocating screw 34 and a threaded sleeve 35. The reciprocating screw 34 is fixedly installed in the dissolving chamber 21 and extends along the length of the dissolving chamber 21. The stirring blade 32 is sleeved on the reciprocating screw 34. The threaded sleeve 35 is rotatably mounted on the mounting plate 31. The threaded sleeve 35 is fixedly connected to the stirring blade 32 and threadedly connected to the reciprocating screw 34. The threaded sleeve 35 is movable along the length of the reciprocating screw 34.

[0033] When the automatic online monitoring device 100 for circulating water is working, the reagent is added to the buffer tube 20, and the rotary drive component 33 is started to drive the threaded sleeve 35 on the mounting plate 31 to rotate, while the reciprocating screw 34 remains stationary. This allows the threaded sleeve 35 to rotate around its own axis through the threaded engagement with the reciprocating screw 34, thereby driving the stirring blade 32 to rotate and stir. On the other hand, the threaded sleeve 35 can reciprocate along the axial direction of the reciprocating screw 34, so that the stirring blade 32 can fully stir the reagent and the liquid to be mixed in the dissolving chamber 21, avoid local stirring blind spots, and promote the full dissolution of the reagent.

[0034] Therefore, through the threaded engagement of the reciprocating screw 34 and the threaded sleeve 35, the stirring blade 32 can be driven to move back and forth along the length of the reciprocating screw 34 while rotating. This enables stirring and mixing at different positions within the dissolution chamber 21, efficiently promoting the dissolution of the agent and further improving the uniformity of dissolution. This solves the technical problem that the uneven dissolution of the agent in the dissolution chamber 21 due to the single rotation of the stirring blade 32 affects the mixing effect, and ensures the accuracy of subsequent monitoring data.

[0035] According to some embodiments of the present invention, such as Figure 4 and Figure 6 As shown, a first fixed shaft 422 is eccentrically disposed on the end face of the movable valve plate 42 away from the fixed valve plate 41, and a wedge block 311 is provided on the mounting plate 31. The opening and closing assembly 43 includes a movable seat 431, which is movably disposed in the dissolving chamber 21 in the vertical direction. A straight groove 432 is provided on the movable seat 431, which extends along the length direction of the buffer tube 20. The first fixed shaft 422 passes through the straight groove 432 and is movable along the length direction of the straight groove 432. A second fixed shaft 433 is provided on the movable seat 431. When the threaded sleeve 35 moves along the length direction of the reciprocating screw 34, the wedge block 311 can abut against the second fixed shaft 433 to drive the second fixed shaft 433 to move upward, so that the first through hole and the second through hole 421 coincide.

[0036] When the automatic online monitoring device 100 for circulating water is working, the reagent is added to the buffer tube 20. The rotary drive assembly 33 drives the threaded sleeve 35 to rotate, causing the stirring blade 32 to rotate and the mounting plate 31 to move back and forth along the reciprocating screw 34. When the wedge 311 abuts against the second fixed shaft 433, the wedge 311 pushes the movable seat 431 upward. The movable seat 431 slides with the first fixed shaft 422 through the straight groove 432, so that the first fixed shaft 422 is driven upward by the movable seat 431. The first fixed shaft 422 can slide in the straight groove 432, avoiding dryness. When the first fixed shaft 422 moves upward, it can drive the movable valve plate 42 to rotate around its own rotation center, so that the first through hole and the second through hole 421 coincide, and the connecting pipe 23 forms a flow channel, so that the drug mixture flows into the main pipe 10 evenly; when the wedge block 311 separates from the second fixed shaft 433, the movable seat 431 resets, that is, the movable seat 431 moves downward, so that the first fixed shaft 422 is driven downward by the movable seat 431, and the movable valve plate 42 rotates in the opposite direction around its own rotation center, so that the first through hole and the second through hole 421 are misaligned, and the flow channel is closed.

[0037] Therefore, through the linkage of wedge 311, movable seat 431 and movable valve plate 42, the opening and closing of main pipe 10 and buffer pipe 20 can be automatically controlled. The whole process relies on the reciprocating movement of mounting plate 31 to automatically link opening and closing component 43, without the need for additional power. This solves the technical problem that the opening and closing component 43 requires additional power to drive and cannot be linked with stirring mechanism 30, resulting in cumbersome operation. With the dual action of stirring, the automation level and dissolution and mixing uniformity of the circulating water automatic online monitoring device 100 can be further improved, ensuring accurate monitoring and reducing production costs.

[0038] In some embodiments of the present invention, such as Figure 4 and Figure 5 As shown, a support 211 is fixedly installed inside the dissolving chamber 21. The opening and closing assembly 43 also includes a guide rod 434, which is mounted on the movable seat 431 and slides with the support 211. The guide rod 434 can guide the movement of the movable seat 431, stabilize the movement trajectory of the movable seat 431, ensure that the movable seat 431 rises and falls in the vertical direction, and prevent the movement of the movable seat 431 from deviating, thereby ensuring that the movable seat 431 reliably drives the movable valve plate 42.

[0039] In addition, such as Figures 4-6As shown, the opening and closing assembly 43 also includes an elastic element 435, which is sleeved on the guide rod 434 and located between the movable seat 431 and the support 211. The elastic element 435 can drive the movable seat 431 to move downward. When the wedge 311 separates from the second fixed shaft 433, the wedge 311 no longer pushes the movable seat 431, and the movable seat 431 can be reset under the elastic force of the elastic element 435, ensuring that the reset of the movable seat 431 is reliable and can ensure the reset stability.

[0040] In some embodiments, the buffer pipe 20 is provided with a base, and the connecting pipe 23 is connected to the base to ensure reliable limiting of the connecting pipe, so that the connecting pipe can reliably communicate with the main pipe 10 and the buffer pipe 20. The fixed valve plate 41 and the support 211 are both fixedly connected to the base, fulfilling the fixing requirements of the fixed valve plate 41 and the support 211. The movable valve plate 42 is rotatably connected to the base, facilitating the rotation of the movable valve plate 42 relative to the fixed valve plate 41, thus meeting the required rotation requirements. For example, the support 211 is connected to the base by bolts or welding.

[0041] According to some embodiments of the present invention, such as Figures 8-10 As shown, the rotary drive assembly 33 includes a rotary driver 331, a bevel gear 332, and a bevel gear ring 333. The rotary driver 331 is mounted on the mounting plate 31, which can fix the rotary driver 331. The bevel gear 332 is located at the drive end of the rotary driver 331, and the bevel gear ring 333 is located on the threaded sleeve 35, and the bevel gear ring 333 meshes with the bevel gear 332. Thus, when the rotary driver 331 is started, the drive end of the rotary driver 331 drives the bevel gear 332 to rotate. The bevel gear 332 drives the bevel gear ring 333 and the threaded sleeve 35 connected to the bevel gear ring 333 to rotate through meshing transmission. The threaded sleeve 35 is threadedly engaged with the fixed reciprocating screw 34, which can drive the stirring blade 32 to rotate and stir the agent, and push the mounting plate 31 to move back and forth along the length of the reciprocating screw 34, thus meeting the required driving requirements. Moreover, the rotary drive assembly 33 has a simple structure, is easy to process and manufacture, and helps to reduce production costs.

[0042] In some embodiments of the present invention, such as Figure 5 , Figure 7 and Figure 8 As shown, the rotary drive assembly 33 also includes a sealing cover 334, which covers the bevel gear 332 and the bevel gear ring 333. The sealing cover 334 can protect the bevel gear 332 and the bevel gear ring 333, solving the technical problem that the bevel gear 332 and the bevel gear ring 333 are easily corroded when exposed to the reagent mixture, resulting in transmission jamming and shortened life. This ensures the long-term stable operation of the bevel gear 332 and the bevel gear ring 333, which is conducive to extending the service life of the automatic online monitoring device for circulating water 100 and ensuring operational stability.

[0043] According to some embodiments of the present invention, such as Figure 3 As shown, the mounting plate 31 has a guide part 312, and the cavity wall of the melting chamber 21 is provided with a guide groove 212. The guide groove 212 cooperates with the guide part 312, so that the mounting plate 31 can move back and forth stably through the cooperation of the guide part 312 and the guide groove 212, ensuring that the mounting plate 31 moves smoothly. This solves the problem that the mounting plate 31 is prone to deviation during reciprocating movement, which leads to unreliable movement. It can ensure the movement accuracy of the mounting plate 31 and ensure precise control.

[0044] In some embodiments, such as Figure 7 and Figure 8 As shown, the mounting plate 31 includes multiple side plates 313, which are interconnected. The connection points of the side plates 313 are sleeved on the reciprocating lead screw 34, which can improve the structural strength of the mounting plate 31 and facilitate its processing and manufacturing. At the same time, the end of one of the side plates 313 away from each other can form a guide part 312. The side plate 313 and the guide groove 212 fit reliably, which simplifies the structure and reduces production costs.

[0045] In embodiments of the present invention, the number of side plates 313 can be flexibly set according to actual conditions. For example, the side plates 313 can be as follows: Figure 7 The number shown is four, but it can also be two, three, five, six or more, all of which are within the protection scope of this invention.

[0046] In some embodiments of the present invention, such as Figure 2 and Figure 3 As shown, there are multiple outlets 22, which are spaced apart along the length of the buffer pipe 20. This allows the reagent mixture to flow into the main pipe 10 through multiple outlets 22, ensuring that the reagent mixture is evenly dispersed at different locations in the main pipe 10. This ensures that the reagent dissolves fully and blends more evenly with the circulating water, preventing local accumulation of the reagent mixture in the main pipe 10. At the same time, the flow of the reagent mixture out through multiple outlets 22 expands the contact range between the reagent mixture and the circulating water, allowing the reagent mixture to blend with the circulating water in the main pipe 10 more quickly and evenly. This avoids local concentration deviations in the main pipe 10 (such as excessively high local concentrations or uneven mixing), ensuring that the circulating water index data obtained by the subsequent automatic online monitoring device 100 is more accurate. Furthermore, the stirring pretreatment in the buffer pipe 20 further improves the uniformity of reagent mixing, providing double assurance for monitoring accuracy.

[0047] In embodiments of the present invention, the number of drug outlets 22 can be flexibly set according to actual conditions. For example, the number of drug outlets 22 can be as follows: Figure 3 The number shown is five, but it can also be two, three, four, six or more, all of which are within the protection scope of this invention.

[0048] In some embodiments, multiple drug outlets 22 are equidistantly distributed along the extension direction of the buffer pipe 20, which can achieve uniform diversion of the drug mixture, ensure that the drug mixture flows into the main pipe 10 evenly, and further ensure the uniformity of drug mixing.

[0049] In some embodiments where the drug outlet 22 is connected to the main pipeline 10 via a connecting pipe 23, and an adjusting mechanism 40 is provided at one end of the connecting pipe 23 near the buffer pipe 20, such as... Figure 1 and Figure 3 As shown, there are multiple connecting pipes 23 corresponding one-to-one with the drug outlet 22, and multiple regulating mechanisms 40. The multiple regulating mechanisms 40 are set one-to-one with the connecting pipes 23, so that the multiple connecting pipes 23 can be controlled in conjunction with the independent regulating mechanism 40. This ensures that the drug mixture is evenly distributed and that the flow rate of each connecting pipe 23 can be flexibly adjusted to avoid local concentration deviations and ensure accurate subsequent monitoring data. At the same time, the failure of a single pipe does not affect the overall operation. This solves the technical problems of the connecting pipes 23 not having an independent control structure and being unable to adjust the flow rate as needed or the failure of a single pipe affecting the overall use. It is beneficial to improve the reliability of the automatic online monitoring device 100 for circulating water.

[0050] In some embodiments where a first fixed shaft 422 is eccentrically arranged on the end face of the movable valve plate 42 away from the fixed valve plate 41 and a wedge 311 is provided on the mounting plate 31, when the mounting plate 31 moves along the length direction of the reciprocating screw 34, the wedge 311 can sequentially push the movable seats 431 at multiple connecting pipes 23, thereby sequentially opening the channels at multiple connecting pipes 23. This enables multiple connecting pipes 23 to be opened sequentially for drug injection, allowing the drug mixture to flow into the main pipeline 10 at multiple points in sequence, avoiding local concentration accumulation in the main pipeline 10, and significantly improving the overall mixing uniformity of circulating water and drugs, providing a more accurate detection basis for the subsequent automatic online monitoring device 100 for circulating water.

[0051] Other configurations and operations of the automatic online monitoring device 100 for circulating water according to embodiments of the present invention are known to those skilled in the art and will not be described in detail here.
