Description

Technical Field

[0001] The present invention belongs to the technical field of boiler feed water treatment, and specifically relates to an intelligent ultrasonic deaerator for boiler feed water treatment. Background Art

[0002] During the operation of a boiler, dissolved oxygen in water can cause serious corrosion to boiler equipment, affecting the service life and operation safety of the boiler. Therefore, it is crucial to deaerate the boiler feed water. Currently, ultrasonic deaerators have been widely used in boiler feed water deaeration.

[0003] During the deaeration process of existing ultrasonic deaerators, although some devices can agitate the water body to a certain extent through stirring and other means to promote the deaeration effect. However, the deaeration position of its ultrasonic deaeration component is relatively fixed. When the device is operating, the deaeration component always acts on a specific area of the water body. For example, the ultrasonic generating device of some ultrasonic deaerators is only installed at a fixed position at the bottom or side of the container, which results in some areas in the water body being difficult to be effectively acted upon by ultrasound, easily forming deaeration dead zones. The long-existing deaeration dead zones will cause the dissolved oxygen content in this area to not be reduced to the standard range, thus affecting the deaeration quality of the entire boiler feed water and posing a threat to the safe and stable operation of the subsequent boiler.

[0020] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the following will clearly and completely describe the technical solutions in the embodiments in conjunction with the accompanying drawings in the embodiments of the present invention. The following embodiments are used to illustrate the present invention.

[0021] Embodiment 1: As Figures 1 to 9 shown, an intelligent ultrasonic deaerator for boiler feed water treatment includes a water storage cover 1 installed with an ultrasonic deaerator body.

[0022] Inside the inner cavity of the water storage cover 1, three pairs of flip plates 4 are installed. On each pair of flip plates 4, a double-crank deaeration assembly is installed. The double-crank deaeration assembly includes a first crank 42 and a second crank 43 that rotate on the flip plate, and a connecting rod 45 is connected between the two. Inside the first crank 42 and the second crank 43, an ultrasonic deaerator contact 44 connected to the ultrasonic deaerator body is installed. On the side wall of the water storage cover 1, an adjusting roller 2 is installed. On the adjusting roller 2, a combined groove 22 composed of a switching groove 221 and a flipping groove 222 is provided, and a protrusion 31 corresponding to the flipping groove 222 is also installed on the adjusting roller 2. On the water storage cover 1, a position-changing assembly is installed. The position-changing assembly includes a push rod 24. The push rod 24 moves horizontally along with the switching groove 221 and pushes the double-crank deaeration assembly to change the deaeration position. On the water storage cover 1, a flipping assembly is installed. The flipping assembly includes a pressing plate 33. The pressing plate 33 slides vertically along the outer contour of the protrusion 31 and pushes the flip plate 4 to turn over.

[0023] As Figures 1 to 9 shown, in the specific implementation, a water inlet pipe 11 is installed on the top of the water storage cover 1, a drain pipe 13 is installed on the side wall of the water storage cover 1, an air outlet pipe 12 is installed on the top of the water storage cover 1 adjacent to the water inlet pipe 11, a valve is installed on the air outlet pipe 12, and connecting flanges 14 are installed on the tops of the water inlet pipe 11 and the drain pipe 13. Through the connecting flanges 14, it is convenient to stably connect with external pipelines, greatly improving the convenience of equipment installation and maintenance. An observation window 16 is installed on the side wall of the water storage cover 1, and scale lines are engraved on the surface of the observation window 16. The scale lines can allow operators to directly observe the water level in the water storage cover 1, so as to accurately control the operation state of the equipment, timely adjust the equipment operation parameters according to the water level change, and ensure the efficient and stable progress of the deaeration work.

[0024] As Figures 1 to 9 shown, further, a vertical plate 15 is installed at the bottom of the water storage cover 1. A base 151 is installed on the top of the vertical plate 15. The base 151 is in a convex platform shape, and installation holes 153 are provided on the surface of the base 151. The installation holes 153 facilitate the stable installation of the equipment at a designated position. A reinforcing rib 152 is installed on the side wall of the vertical plate 15, and the other end of the reinforcing rib 152 is installed on the base 151, and the reinforcing rib 152 is triangular. The triangular reinforcing rib 152 greatly enhances the connection stability between the vertical plate 15 and the base 151, effectively improving the overall structural strength of the equipment, ensuring that the equipment can withstand various external forces during long-term operation, and guaranteeing the reliability and safety of equipment operation.

[0025] Example 2: The difference between this example and Example 1 is: As Figures 1 to 9As shown in the figure, mounting plates 171 are installed at both ends of the water storage cover 1. A notch 172 is installed at the center of the mounting plate 171. And an end cover 17 is installed on the side wall of the mounting plate 171 through bolts. A driving motor 21 is installed on the end cover 17. The output end of the driving motor 21 is installed with a synchronous shaft 211. And the synchronous shaft 211 movably penetrates through the end cover 17. And the synchronous shaft 211 is connected to the adjusting roller 2. The above structure specifically defines the installation position of the driving motor 21.

[0026] Embodiment 3: The difference from Embodiment 2 in this embodiment is that as Figures 1 to 9 shown, fixed seats 41 are installed at both ends of the rotation center of the flip plate 4. Among them, the fixed seat 41 provides stable support for the rotation of the flip plate 4. A rocker arm 411 is installed at the rotation center of the flip plate 4. A strip-shaped groove 412 is opened on the rocker arm 411. A slide bar 332 is vertically slidably arranged inside the strip-shaped groove 412. The top of the slide bar 332 is installed with a connecting plate 331. The connecting plate 331 is connected to the bottom of the pressing plate 33. When the rotating protrusion 31 contacts the pressing plate 33, the pressing plate 33 is squeezed and moves downward. The pressing plate 33 slides downward along the positioning rod 32. The positioning spring 322 at the bottom of the positioning rod 32 is compressed synchronously. It is convenient for later operation through the positioning spring 322. And when the pressing plate 33 moves downward, the connecting plate 331 and the slide bar 332 at the bottom of the pressing plate 33 slide in the strip-shaped groove 412 of the rocker arm 411, causing the rocker arm 411 to deflect. Furthermore, it drives the coaxial rocker arm 411 to rotate synchronously. Furthermore, it drives the rotation center of the flip plate 4 to rotate, thus realizing the flipping of the flip plate 4. This structural design cleverly realizes the effective transmission of the vertical movement of the pressing plate 33 and the flipping action of the flip plate 4. When the pressing plate 33 moves vertically under the action of other components, it can accurately drive the flip plate 4 to rotate around its rotation center, realizing the flipping operation of the flip plate 4, and further expanding the range of deoxidation positions.

[0027] As Figures 1 to 9As shown, in the specific implementation manner, a first fixing plate 421 is installed on the side wall of the first crank 42, a second fixing plate 431 is installed on the side wall of the second crank 43, an ultrasonic deaerator contact 44 is installed between the second fixing plate 431 and the first fixing plate 421, and the included angle between the first crank 42 and the second crank 43 is ninety degrees. This special angle design enables the double-crank deaeration assembly to perform targeted deaeration on the vertical and horizontal directions of the water body when working. A clamping seat 451 is installed at the rotation centers of the first crank 42 and the second crank 43, and the clamping seat 451 is installed on the turning plate 4. A clamping shaft 422 is installed at the rotation center of the first crank 42, the clamping shaft 422 movably penetrates through the clamping seat 451, a torsion spring 424 is sleeved on the outer wall of the clamping shaft 422, one end of the torsion spring 424 is clamped on the clamping seat 451, and the other end of the torsion spring 424 is clamped on the side wall of the first crank 42. When the first crank 42 rotates, the torsion spring 424 deforms to store energy. During the subsequent reset process, the torsion spring 424 releases energy to drive the first crank 42 to reset. This not only enables the double-crank deaeration assembly to quickly return to the initial or appropriate position to prepare for the next round of deaeration work, but also can disturb the surrounding water body again during the reset process, strengthen the water body mixing effect, further promote the uniform dispersion of dissolved oxygen, and improve the deaeration efficiency.

[0028] As Figures 1 to 9 shown, further, a limit seat 241 is movably arranged on the side wall of the ejector rod 24, the limit seat 241 is welded on the side wall of the water storage cover 1, a push rod 243 is installed on the side wall of the ejector rod 24, a swing arm 423 is installed at the rotation center of the first crank 42, and the swing arm 423 is in an inclined state. The push rod 243 is in contact with the swing arm 423. A limit plate 242 is installed at the end of the ejector rod 24, and the diameter of the limit plate 242 is larger than the diameter of the ejector rod 24. This effectively prevents the ejector rod 24 from detaching from other components during movement and ensures the stability of the equipment operation. A synchronous frame 23 is installed on the ejector rod 24, a synchronous slider 223 is installed at the top of the synchronous frame 23, the synchronous slider 223 slides on the combined groove 22, a guide rod 231 is movably penetrated and inserted through the side wall of the synchronous frame 23, a guide seat 232 is installed at the end of the guide rod 231, the guide seat 232 is installed at the bottom of the water storage cover 1, and a positioning spring 322 is sleeved on the guide rod 231. One end of the positioning spring 322 is clamped on the synchronous frame 23, and the other end of the positioning spring 322 is clamped on the guide seat 232. During the movement of the ejector rod 24, the positioning spring 322 can absorb vibrations and impacts to a certain extent to ensure the smooth operation of the equipment. At the same time, when the ejector rod 24 needs to be reset, the positioning spring 322 can provide a certain reset assist force to make the equipment operation more efficient and stable.

[0029] As Figures 1 to 9As shown in the figure, further, a synchronous plate 3 is installed on the pressing plate 33, and the synchronous plate 3 is attached to the bottom of the adjusting roller 2. A positioning rod 32 is movably installed through the synchronous plate 3. The bottom of the positioning rod 32 is installed on the water storage cover 1, and a positioning plate 321 for anti-disengagement is installed at the top of the positioning rod 32. A positioning spring 322 is sleeved on the positioning rod 32. One end of the positioning spring 322 is clamped to the bottom of the synchronous plate 3, and the other end of the positioning spring 322 is clamped to the water storage cover 1. When the protrusion 31 on the adjusting roller 2 contacts and presses the pressing plate 33 to move vertically downward, the pressing plate 33 slides along the positioning rod 32, and the positioning spring 322 is compressed. The positioning spring 322 stores energy during the compression process. When the protrusion 31 is separated from the pressing plate 33, the positioning spring 322 releases energy, driving the pressing plate 33 to reset, ensuring the continuity and stability of the equipment operation, and providing reliable power support for the turning operation of the turning plate 4.

[0030] The implementation principle of an intelligent ultrasonic deaerator for boiler feed water treatment of the present invention is as follows: First, the operator fills the water storage cover 1 with boiler water through the water inlet pipe 11, and then cleans the oxygen in the boiler water through the ultrasonic deaerator contact 44 of the ultrasonic deaerator body. The cleaned oxygen can be discharged outward through the air outlet pipe 12, and the treated water can be discharged outward through the drain pipe 13 on the water storage cover 1. The ultrasonic deaerator body (not shown in the figure) mainly realizes deaeration based on the cavitation effect of ultrasonic waves. When the ultrasonic deaerator contact 44 works, it emits high-frequency ultrasonic waves into the boiler water. During the propagation of ultrasonic waves, tiny negative pressure regions will be formed in the water. In these regions, the pressure inside the liquid is lower than the saturated vapor pressure of the liquid, causing the liquid to rapidly vaporize to form tiny bubbles, which is the cavitation phenomenon. With the continuous action of ultrasonic waves, these tiny bubbles continuously vibrate, grow, and collapse. At the moment when the bubbles collapse, local high temperature, high pressure, strong shock waves, and microjets will be generated. This extreme physical environment can break the chemical bonds between oxygen and water molecules in the water, causing the dissolved oxygen in the water to escape from the water. At the same time, the shock waves and microjets can also accelerate the diffusion rate of oxygen in the water, making it easier to aggregate and form larger bubbles, and then discharging from the water, ultimately achieving the purpose of deaerating the boiler water.

[0031] During the operation of the ultrasonic deaerator contact 44, the operator starts the drive motor 21. The drive motor 21 drives the synchronous shaft 211 to rotate, and the synchronous shaft 211 then drives the adjusting roller 2 to rotate. When the adjusting roller 2 rotates, the position of the combined groove 22 changes, and the position of the switching groove 221 in the combined groove 22 changes synchronously, thereby driving the synchronous slider 223 on the switching groove 221 to move to the right. The synchronous slider 223 drives the ejector rod 24 to move horizontally through the synchronous frame 23. The synchronous frame 23 slides along the guide rod 231, playing a guiding role. When the synchronous frame 23 slides, it can compress the guide spring 233, which facilitates the later reset operation through the compressed guide spring 233.

[0032] During the movement of the ejector rod 24, the ejector rod 24 slides along the limit seat 241, and the limit plate 242 mainly serves to prevent the ejector rod 24 from separating from the limit seat 241. When the ejector rod 24 moves, the push rod 243 on the side wall slides synchronously. The push rod 243 pushes the swing arm 423 to flip, and the swing arm 423 drives the first crank 42 to rotate through the coaxial clamping shaft 422. And during the above process, the torsion spring 424 as a whole can be twisted, which is convenient for the later reset operation. When the first crank 42 rotates around its rotation center, the first crank 42 drives the second crank 43 to rotate synchronously through the connecting rod 45, realizing the transposition of the double-crank deaeration assembly. The ultrasonic deaerator contact 44 connected to the first crank 42 initially deaerates in the vertical direction, while the ultrasonic deaerator contact 44 connected to the second crank deaerates on the horizontal plane. When switched, the working positions of the two change. During this process, as the first and second cranks rotate, it will drive the surrounding water to flow, playing a role in mixing the water. On the one hand, the mixed water helps to break the possible dissolved oxygen concentration gradient in the water, enabling the originally unevenly distributed dissolved oxygen to be more evenly dispersed in the water, making the subsequent deaeration operation more comprehensive and efficient; on the other hand, it can make the ultrasonic deaerator contact 44 cover a wider area, avoiding deaeration dead spots; and for the water bodies at different height levels in the water storage cover 1, more accurate and efficient deaeration operations can be carried out, effectively improving the overall deaeration effect, ensuring that the boiler water at each height can reach the ideal deaeration standard and meeting the strict requirements of the boiler for low dissolved oxygen content in the feed water.

[0033] When the synchronous slider 223 slides into the flipping groove 222, the above transposition operation ends synchronously. But at this time, the protrusion 31 on the adjusting roller 2 rotates downward at this time. The protrusion 31 contacts the pressing plate 33 and squeezes the pressing plate 33 to move vertically downward at this time. The pressing plate 33 slides downward along the positioning rod 32 at this time, and the positioning spring 322 at the bottom of the positioning rod 32 is compressed synchronously, which facilitates the later operation through the positioning spring 322.

[0034] When the pressing plate 33 moves downward, the connecting plate 331 and the sliding rod 332 at the bottom of the pressing plate 33 slide in the strip-shaped groove 412 of the rocker arm 411, and then the rocker arm 411 rotates synchronously, driving the rotation center of the turning plate 4 to rotate, thus realizing the turning of the turning plate 4.

[0035] When the turning plate 4 turns, the position of the transposition assembly becomes vertical, which further expands the position range of deaeration. The original deaeration area in the horizontal direction can extend to more positions in the vertical direction due to the vertical change of the transposition assembly, further expanding the reachable range of the ultrasonic deaerator contact 44 and greatly improving the comprehensiveness of deaeration. Moreover, when the turning assembly rotates following the turning plate 4, the swing arm 423 and the push rod 243 separate. At this time, under the action of the torsion spring 424, the first crank 42 will rebound and reset to a certain extent. This change brings many benefits. First, it can enable the double-crank deaeration assembly to quickly stabilize in the new position, providing a stable structural basis for subsequent continuous and efficient deaeration. Second, the rebound of the torsion spring 424 drives the first crank 42 and the second crank 43 to reset, which will further disturb the surrounding water body, further strengthening the water body mixing effect, promoting the more uniform distribution of dissolved oxygen, and making the deaeration process more efficient.
