Description

Technical Field

[0001] This invention relates to the technical field of condensers, and in particular to a condenser condenser tube flow guiding device. Background Technology

[0002] In industrial heat exchange systems, the condenser is a key device for transferring heat from boiler flue gas and other heat source media to the heat exchange medium. Its operational stability directly affects the efficiency and safety of the entire system. The condenser tubes are the core heat exchange elements of the condenser. The heat exchange medium flows within the tubes and absorbs heat, often facing the problem of a rapid increase in pressure due to the thermal expansion of the medium. Traditional condenser flow guiding devices typically distribute the medium to each condenser tube using simple distributors or manifolds, lacking effective control over the flow state of the medium. This easily leads to the following problems: First, the heat exchange medium expands in volume after absorbing heat, resulting in excessively high instantaneous pressure peaks within the tubes. Long-term operation can easily cause localized expansion and cracking of the condenser tubes, or even tube rupture accidents, seriously affecting equipment lifespan and production safety. Second, the medium is prone to forming disordered turbulence before being distributed, leading to uneven distribution of flow and pressure entering each condenser tube. Some pipes suffer from insufficient heat exchange due to insufficient flow, while others experience increased pressure shocks due to excessive flow, resulting in low overall heat exchange efficiency.

[0026] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0027] Many specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways different from those described herein, and those skilled in the art can make similar extensions without departing from the spirit of the invention. Therefore, the invention is not limited to the specific embodiments disclosed below.

[0028] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that is mutually exclusive with other embodiments.

[0029] Example 1, referring to Figures 1 to 7This is the first embodiment of the present invention. This embodiment provides a condenser condenser tube flow guiding device. The condenser condenser tube flow guiding device includes uniformly introducing microbubbles into the heat exchange medium through a gas pressure component 2 and an air inlet component 4. When the medium is heated and expands, the bubbles are compressed, absorbing the volume increase and significantly reducing the instantaneous pressure peak value borne by the inner wall of the condenser tube. At the same time, the bubbles change the density and compressibility of the medium, dissipating the flow impact energy at the bend, fundamentally avoiding the tube rupture problem caused by thermal expansion.

[0030] Specifically, the vortex shell 1 has a cylindrical structure with a cylindrical guide cavity 11 at its center. A guide rotor 12 is rotatably mounted inside the guide cavity 11 via bearings. The top of the vortex shell 1 is fixedly and sealed to a pneumatic assembly 2 by bolts. The top of the guide rotor 12 is fixedly connected to the drive shaft inside the pneumatic assembly 2 via a coupling. Driven by an external motor, the guide rotor 12 rotates inside the guide cavity 11, applying centrifugal force to the incoming heat exchange medium. This forces the heat exchange medium to undergo spiral acceleration along the inner wall of the guide cavity 11, thereby transferring kinetic energy to the heat exchange medium and providing power for subsequent diversion and pressurization.

[0031] Specifically, the vortex shell 1 is welded with a discharge pipe 13 and an input pipe 14 along its tangential direction. The input pipe 14 is used to connect to the heat medium outlet of the boiler flue gas heat exchanger and receive the heat exchange medium carrying heat. One end of the discharge pipe 13 is fixedly connected to a flow divider 3 via a flange. The tangential design of the vortex shell 1 allows the heat exchange medium entering from the input pipe 14 to impact the guide rotor 12 with minimal resistance. At the same time, the accelerated medium also smoothly enters the discharge pipe 13 along the tangential direction, avoiding energy loss and turbulence caused by right-angle turns.

[0032] Specifically, the flow distribution assembly 3 includes a fluid pipe 31 fixedly connected to the discharge pipe 13 via flanges and bolts. The fluid pipe 31 is a stainless steel round pipe with a precision-machined inner wall. A flow guiding structure 32 is fixedly installed inside the fluid pipe 31. The flow guiding structure 32 includes a cone 321, which is coaxially welded to the inner wall of the fluid pipe 31 via a support at its bottom. Several spiral flow guiding grooves 322 are precision milled on the outer circumference of the cone 321. When the heat exchange medium enters the fluid pipe 31 from the discharge pipe 13 and impacts the cone 321, the medium is forced into the flow guiding grooves 322. The spiral structure of the flow guiding grooves 322 transforms the linear flow of the medium into a rotating flow, and uses centrifugal force to evenly distribute the medium into each flow distribution channel, effectively preventing the formation of disordered turbulence before the medium is distributed, and ensuring that the flow rate and pressure of the medium distributed to each condenser tube remain consistent.

[0033] Specifically, an air intake assembly 4 is provided inside the fluid pipe 31. The air intake assembly 4 includes a frustum-shaped guide platform 41. Several support plates 42 are integrally formed on the outer circumference of the guide platform 41. Each support plate 42 extends radially along the fluid pipe 31, and its outer end penetrates the pipe wall of the fluid pipe 31 and is welded and sealed to the pipe wall. The guide platform 41 and the support plates 42 are drilled together to form a guide pipe 43. The support plates 42 not only serve to fix the guide platform 41, but the guide pipe 43 opened inside them also forms a gas channel from the outside of the fluid pipe 31 to the central area of ​​the internal guide platform 41. This design of integrating the gas channel inside the support plate 42 avoids the need to set up an additional gas pipe inside the fluid pipe 31 and reduces interference with the main flow field.

[0034] Specifically, the pneumatic assembly 2 includes a cylindrical upper housing 21. The bottom end of the upper housing 21 is sealed to the top end of the vortex housing 1 by bolts. Inside the upper housing 21, a guide shaft 22 is vertically mounted via bearings. The bottom end of the guide shaft 22 is fixedly connected to the top end of the guide rotor 12 via a coupling, so that the rotational motion of the guide rotor 12 can be directly transmitted to the guide shaft 22. A crankshaft assembly 23 is fixedly mounted on the top end of the guide shaft 22.

[0035] One end of the connecting rod 232 of the crankshaft assembly 23 is hinged to the piston 24 by a pin, and one end of the upper housing 21 is fixedly connected to the cylinder 25 by bolts. The inner wall of the cylinder 25 is precision honed, and the piston 24 is slidably sealed inside the cylinder 25. The end cap of the cylinder 25 away from the upper housing 21 is respectively equipped with an intake pipe 26 with a one-way valve and an exhaust pipe 27 with a one-way valve. When the guide rotor 12 rotates, it drives the guide shaft 22 and the crankshaft assembly 23 to rotate.

[0036] The crankshaft assembly 23 converts the rotational motion into the reciprocating linear motion of the piston 24 within the cylinder 25. When the piston 24 retracts, the one-way valve of the intake pipe 26 opens, drawing in external air into the cylinder 25. When the piston 24 advances, the one-way valve of the intake pipe 26 closes, and the one-way valve of the jet pipe 27 opens, compressing and pumping out the air. Thus, the pneumatic assembly 2 utilizes the rotational power of the guide rotor 12 itself to continuously generate compressed air without an external air source.

[0037] Example 2, refer to Figures 2-7 This is the second embodiment of the present invention, which is based on the previous embodiment.

[0038] Specifically, the inner flow channel of the fluid pipe 31 is composed of two conical cavities 33 with opposite cone tips. For ease of description, the conical cavity 33 near the end of the discharge pipe 13 is defined as the first conical cavity 33, and the conical cavity 33 near the end of the communicating vessel 34 is defined as the second conical cavity 33. The large-diameter end of the first conical cavity 33 is fixedly connected to the discharge pipe 13, and its small-diameter end is interconnected with the small-diameter end of the second conical cavity 33. The large-diameter end of the second conical cavity 33 is connected to the communicating vessel 34.

[0039] The conical body 321 is fixedly disposed inside the second conical cavity 33, and the outer conical surface of the conical body 321 is tightly fitted with the inner wall of the conical cavity 33, with only a few spiral guide grooves 322 between them as medium flow channels. The outlet of the guide pipe 43 of the air intake assembly 4 is located near the small-diameter end of the first conical cavity 33, that is, in the throat region of the flow channel, where the flow velocity is the highest and the static pressure is the lowest, which is conducive to forming a negative pressure to draw in gas.

[0040] During operation, the heat exchange medium enters the first conical cavity 33 from the discharge pipe 13, flows from the large end to the small end, the flow velocity increases sharply, the static pressure decreases significantly, and a local negative pressure zone is formed in the throat region. The outlet of the guide pipe 43 located in this negative pressure zone draws in the compressed air generated by the air pressure component 2, mixes it thoroughly with the high-speed medium, and forms uniform micro bubbles. Subsequently, the medium carrying the bubbles enters the second conical cavity 33 and rotates forward along the spiral guide groove 322 on the outer periphery of the cone 321. In the gradually expanding flow channel, the flow velocity gradually decreases and the pressure gradually recovers, and finally smoothly enters the communicating vessel 34 and is distributed to each branch pipe 35.

[0041] The opposing structures of the double conical cavities 33 form a Venturi tube-type flow channel. When the heat exchange medium flows from the large end to the small end of the first conical cavity 33, the flow velocity increases sharply and the static pressure decreases, forming a negative pressure zone at the throat. This negative pressure zone is located near the outlet of the guide pipe 43 of the air intake assembly 4, thereby actively drawing in air and mixing it with the medium to form uniform microbubbles.

[0042] Specifically, the air intake assembly 4 also includes a guide ring 44, which is a hollow annular cavity. It is fixedly fitted onto the outer peripheral wall of the fluid pipe 31 by clamps. Multiple hollow connecting pipes 45 are integrally formed or welded onto the inner side wall of the guide ring 44. Each connecting pipe 45 is aligned with the corresponding guide pipe 43 in the support plate 42 and connected by a sealing joint. An air intake pipe 46 is welded onto the outer peripheral wall of the guide ring 44. The jet pipe 27 is sealed to the air intake pipe 46 through a pressure-resistant hose. Compressed air from the air pressure assembly 2 enters the annular cavity of the guide ring 44 through the jet pipe 27 and the air intake pipe 46 in sequence, and is then evenly distributed to each connecting pipe 45 and then enters the guide pipe 43 in each support plate 42. The guide ring 44 plays the role of collecting and distributing air, ensuring that the air pressure and flow rate at the outlet of each guide pipe 43 are consistent.

[0043] Specifically, the guide groove 322 is spirally arranged, and the spiral direction is the same as the rotation direction of the guide rotor 12. The cross-sectional shape of the guide groove 322 is semi-circular, and its cross-sectional area gradually increases from the tip of the cone 321 (i.e., the direction of the cone 321 towards the first cone cavity 33) to the end of the guide groove 322 (i.e., the direction of the cone 321 away from the first cone cavity 33). This gradually expanding spiral groove design allows the channel cross-sectional area to gradually increase, the flow velocity to gradually decrease, and the pressure to gradually recover during the flow of the medium, converting some kinetic energy into pressure energy, thereby smoothly sending the medium into the subsequent diversion pipe 35 and reducing the impact and noise caused by sudden pressure changes.

[0044] Specifically, the intake assembly 4 also includes a guide rod 47 that slides with the center hole of the air guide 41. One end of the guide rod 47 is equipped with a tension spring. A circular outer ring 48 is fixedly fitted around the outer circumference of the guide rod 47. Several connecting plugs 49 are fixedly connected to the side of the outer ring 48 facing the air guide 41 via a thin rod. Each connecting plug 49 is aligned with the corresponding outlet of the air guide tube 43 and precisely slidably inserted into the port of the air guide tube 43. The tension spring is connected to the air guide 41 and is used to pull the guide rod 47 to move, allowing the connecting plugs 49 to be tightly inserted into the interior of the air guide tube 43. Each connecting plug 49 has several small connecting holes 410 axially formed inside. When piston 24 pushes air from inside cylinder 25 into guide ring 44 through jet pipe 27, the internal pressure of guide ring 44 increases and is discharged through guide pipe 43. At this time, the internal pressure of guide pipe 43 acts on connecting plug 49, pushing connecting plug 49 out so that the outlet end of connecting hole 410 is exposed in guide pipe 43, so as to pump high-pressure gas into heat exchange medium. After the gas is discharged, under the action of tension spring, connecting plug 49 returns, realizing precise bubble injection control. Connecting hole 410 is used to connect the negative pressure area inside fluid pipe 31 with the compressed air area inside guide pipe 43 when connecting plug 49 is partially inserted, so as to realize the mixing of gas and medium.

[0045] Specifically, the flow distribution assembly 3 also includes a communicating vessel 34 fixedly connected to the end of the fluid pipe 31 via a flange. The communicating vessel 34 is a distribution chamber with one inlet and multiple outlets. One end of the communicating vessel 34 is connected to multiple flow distribution pipes 35. The number of flow distribution pipes 35 is equal to the number of flow guide channels 322, and the inlet axis of each flow distribution pipe 35 is aligned with the end outlet axis of a corresponding flow guide channel 322 and is on the same center line. This one-to-one direct docking method ensures that the heat exchange medium flowing out from each flow guide channel 322, after being uniformly distributed and stabilized, can directly enter the corresponding flow distribution pipe 35 without interference, and then be transported to each condenser tube of the condenser.

[0046] Specifically, the guide rotor 12 includes a main shaft 121, which is rotatably mounted inside the vortex housing 1 via two sets of ball bearings to ensure smooth rotation. The top end of the main shaft 121 extends out of the top cover of the vortex housing 1 and is fixedly connected to the bottom end of the guide shaft 22 via a rigid coupling, achieving synchronous torque transmission. Several guide disks 122 are fixedly mounted on the outer periphery of the main shaft 121 via key connections or heat fittings. Each guide disk 122 has several evenly distributed rotor slots 123 machined on its outer periphery. The rotor slots 123 on the two guide plates 122 are staggered in the circumferential direction, that is, the center line of the rotor slot 123 on one guide plate 122 does not coincide with the center line of the rotor slot 123 on the adjacent guide plate 122, forming a staggered arrangement. This allows the medium to be continuously cut and guided by the rotor slots 123 on different guide plates 122 when it flows through the guide rotor 12, generating strong but orderly eddies, which greatly improves the internal energy transfer efficiency of the medium, and effectively avoids the periodic pressure pulsation and resonance that may be caused by slot alignment.

[0047] Specifically, multiple support plates 42 are provided, evenly distributed at the same angle along the circumference of the guide platform 41. The end of the support plate 42 away from the guide platform 41 is welded and fixed to the inner wall of the fluid pipe 31. The weld point is polished and the surface is smooth. At the same time, this end of the support plate 42 passes through a pre-machined through hole on the wall of the fluid pipe 31 and extends about 5 mm beyond the outside of the pipe wall. The protruding part is also sealed and welded to the pipe wall. The double-sided welding installation method ensures the absolute strength and sealing of the connection between the support plate 42 and the fluid pipe 31, preventing high-pressure medium from leaking from the weld gap.

[0048] Specifically, the crankshaft assembly 23 includes a crank 231 and a connecting rod 232. The center part of the crank 231 is fixedly mounted on the top of the guide shaft 22 via a keyway and a flat key, and rotates synchronously with the guide shaft 22. An eccentric journal is provided on the crank 231 at an off-center position. The large end of the connecting rod 232 is sleeved on the eccentric journal through a needle roller bearing to form a rotatable connection. The small end of the connecting rod 232 is hinged to the top of the piston 24 through a piston pin. This crank 231 and connecting rod 232 mechanism accurately converts the continuous circular motion of the guide shaft 22 into the reciprocating linear motion of the piston 24.

[0049] Specifically, one end of the connecting pipe 45 is fixedly connected to the inner wall of the guide ring 44 and aligned with the air outlet on the inner wall. The other end of the connecting pipe 45 is fixedly connected to the outer circumferential surface of the support plate 42 through a compression fitting. The compression fitting has a sealing ring inside to ensure that the connection is leak-proof. The inner cavity of the connecting pipe 45 and the inner cavity of the guide pipe 43 inside the support plate 42 are interconnected through the fitting, forming a complete and sealed gas delivery channel from the guide ring 44 to the outlet of the end of the guide pipe 43.

[0050] In use, firstly, the input pipe 14 is connected to the heat exchange medium input pipe 14 via a flange. Then, the external motor is started to drive the guide rotor 12 inside the vortex housing 1 to rotate at high speed. The heat exchange medium enters the guide cavity 11 tangentially from the input pipe 14 and is pushed by the guide disk 122 and rotor groove 123 on the rotating guide rotor 12. After gaining high kinetic energy, it flows out at high speed along the discharge pipe 13. At the same time, the guide rotor 12 drives the guide shaft 22 and crankshaft assembly 23 to rotate, driving the piston 24 of the pneumatic assembly 2 to reciprocate and generate compressed air. The compressed air passes sequentially through the jet pipe 27, the intake pipe 46, the guide ring 44, the connecting pipe 45, and the support plate. The guide tube 43 inside 42 eventually sprays out from the outer periphery of the guide platform 41. Then, the high-speed heat exchange medium enters the double conical cavity 33 flow channel of the fluid tube 31. When it flows through the first conical cavity 33, the flow velocity increases sharply, and a local negative pressure is generated at the moment of entering the second conical cavity 33. This negative pressure actively draws in the compressed air at the outlet of the guide tube 43, so that the air is fully mixed with the heat exchange medium in the form of micro bubbles. The mixed medium continues to flow through the spiral guide groove 322 on the surface of the conical body 321. Under the guidance of the guide groove 322, the medium rotates and flows, and is evenly distributed into each branch tube 35, and then enters each condenser tube of the condenser.

[0051] When the heat exchange medium containing air bubbles absorbs heat from the boiler flue gas in the condenser tube, the medium itself expands due to heat. At this time, the tiny air bubbles evenly distributed inside the medium play a buffering role: the air bubbles are compressed under pressure, absorbing the volume increase of the medium due to thermal expansion, thus significantly reducing the instantaneous pressure peak on the inner wall of the condenser tube. At the same time, the presence of air bubbles changes the density and compressibility of the medium. When the medium flows in the bend of the condenser tube, the air bubbles can absorb and dissipate the flow impact energy, effectively mitigating the impact force of the fluid on the tube wall. Finally, the heat exchange medium that has absorbed enough heat flows out from the outlet of the condenser tube, completing the entire flow guidance and heat exchange process. This process fundamentally prevents the problem of condenser tube rupture caused by the thermal expansion of the heat exchange medium.

[0052] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit it. Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of the present invention without departing from the spirit and scope of the technical solutions of the present invention, and all such modifications or substitutions should be covered within the scope of the claims of the present invention.
