Description

Technical Field

[0001] This invention relates to the field of condenser technology, and more particularly to a high-efficiency integrated evaporative condenser. Background Technology

[0002] An evaporative condenser consists of a fan, condensing coils, and a housing. It utilizes the partial evaporation of spray water outside the coils to absorb heat from the high-temperature gaseous refrigerant inside, gradually cooling the refrigerant from a gaseous state to a liquid state. The working principle is as follows: superheated, high-pressure refrigerant gas passes through the condensing coils in the evaporative condenser, where the high-temperature gaseous refrigerant exchanges heat with the spray water and air outside the coils. Specifically, the gaseous refrigerant enters the coils from the top and is gradually condensed into liquid refrigerant from top to bottom. The powerful airflow from the accompanying induced draft fan ensures that the spray water completely and evenly covers the surface of the coils. The water, aided by the airflow, greatly enhances the heat exchange effect. The heated spray water partially turns into a gaseous state, and the latent heat of vaporization of the water is carried away by the airflow.

[0003] Patent document CN2024104715810 discloses an evaporative condenser, belonging to the technical field of heat exchange equipment. This invention includes a condenser shell and a descaling pump. An axial flow fan is installed on the top of the condenser shell, and a heat exchange mechanism is installed inside the condenser shell. The heat exchange mechanism consists of heat exchange coils and a heat exchange box, and also includes: a heat exchange spray assembly, a scraping heat conduction assembly, and a magnetic flow control assembly. This evaporative condenser achieves efficient heat exchange and condensation processes through the synergistic effect of the scraping heat conduction assembly and the magnetic flow control assembly, thereby ensuring the normal operation and high efficiency of the refrigeration system. The scraping heat conduction assembly can scrape and clean oil films and scale on heat exchange coils of different diameters, thereby improving their heat exchange efficiency.

[0004] However, in actual use, the inventors found that the spray water flow rate at the elbow of the condenser coil was slow, the heat exchange effect was poor, the flushing effect was weak, the stroke was long, and it was easy to form scale, which was difficult to clean. Summary of the Invention

[0005] The purpose of this invention is to address the shortcomings of existing technologies by providing a high-efficiency integrated evaporative condenser. Through a bend-tube processing component in conjunction with the condensing coil, it automatically and alternately descales and regulates the water film on the bend, cleaning the scale on the outer wall of the bend, preventing scale corrosion, and extending the service life of the condensing coil. It also scrapes away excess spray water outside the water film on the bend, increasing heat exchange efficiency. This solves the technical problems of slow flow rate, poor heat exchange, weak flushing effect, long travel distance, easy scaling, and difficulty in cleaning of the spray water at the bend of the condensing coil.

An annular airbag is disposed on the outer wall of the bearing ring and is connected to the piston channel. The annular airbag uses air pressure to drive the piston column to bring two sets of semi-circular scraping rings together inward, causing the two sets of semi-circular scraping rings to combine into a circle on the outer wall of the bend.

[0009] Preferably, the descaling unit further includes: The U-shaped moving frame is slidably disposed on the tube sheet and elastically disposed on the tube sheet by a first elastic element, and the shaft is located inside the arc-shaped part of the U-shaped moving frame; A stop block is provided on the straight part of the U-shaped moving frame and is used to abut against the tube plate to limit the movement of the U-shaped moving frame.

Several sets of scale receiving plates are arranged on one side of the scale collection box at an upward angle. The scale receiving plates are connected to the tube sheet and are respectively located below the bend.

[0014] Preferably, the water collector includes: The bracket is disposed on the top of the housing; Several sets of C-shaped water-collecting plates are horizontally arranged on the support. The C-shaped water-collecting plates are formed by bending a corrugated plate.

[0015] Preferably, the water collection unit includes: Water-enclosing plates are disposed on both sides of the water-collecting surface groove at the lower part of the C-shaped water-collecting plate; A collection box, and several sets of the collection boxes are disposed on the impact surface of the lower part of the C-shaped water collection plate; A drainage pipe is inclined downward on the collection box and is used to guide the water in the collection box to the water collection surface groove at the lower part of the adjacent set of C-shaped water collection plates; A circulation inlet pipe is installed on the support and is connected to the water-enclosing plate on one side of the C-shaped water-collecting plate.

On the other hand, the spray water scraped off on the bent tube can be discharged to the surrounding area to avoid excessive spray water accumulating at the connection between the bent tube and the tube sheet, which would result in a thicker water film at the connection between the bent tube and the tube sheet, affecting the heat exchange effect. The scraped dirt is also automatically collected and the spray water is purified. (2) The water collection component set in this invention can, on the one hand, condense and collect water droplets carried by steam, increase the collision contact area between steam and water collector, guide water droplets to the water collection surface under the C-shaped water collector, temporarily store the collected water droplets, and reduce the situation where water droplets fall again and are carried by steam a second time; on the other hand, it can send the water collected by the water collector directly back to the spray water pool, and use the circulating spray water to cool the C-shaped water collector, increasing the condensation effect of steam in the water collector.

[0017] In summary, this equipment has the advantages of good cleaning effect, high heat exchange effect, and good water collection effect, and is especially suitable for the field of condenser technology. Attached Figure Description

[0035] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.

[0036] Example 1 like Figures 1-11 As shown, a high-efficiency integrated evaporative condenser includes a condenser coil 2, a spray system 3, a fan 4, and a bend processing assembly 5 arranged on both sides of the condenser coil 2, which are installed inside the housing 1. The bend processing assembly 5 includes a water film regulating unit 51 disposed on the tube sheet 21 of the condenser coil 2, a descaling unit 52 disposed on the water film regulating unit 51, and a scale collection unit 53 disposed on the tube sheet 21. The water film regulating unit 51 includes a shaft 511 rotatably mounted on the tube sheet 21 and located on the coaxial line of the bend of the condenser coil 2, several sets of U-shaped supports 512 mounted on the shaft 511, a retainer 513 mounted at the end of the U-shaped support 512, a bearing ring 514 rotatably mounted on the retainer 513 and sleeved on the outside of the bend, a scraper ring 515 mounted on the inner wall of the bearing ring 514, several sets of water-throwing holes 516 opened on the bearing ring 514 and located on both sides of the scraper ring 515, a ring gear 517 mounted on one side of the scraper ring 515, and a first helical toothed gear 518 rotatably mounted on the U-shaped support 512. The water film conditioning unit 51 further includes: The second helical toothed gear 519 is rotatably mounted on the U-shaped support 512 and is coaxially mounted with the first helical toothed gear 518. U-shaped stationary frame 5191 is disposed on the tube sheet 21, and the arc-shaped part of the U-shaped stationary frame 5191 is coaxial with the shaft 511. A semi-ring gear 5192 is disposed on the arc-shaped part of the U-shaped stationary frame 5191, which is used to drive the second helical toothed gear 519 to rotate. The shaft 511 drives the bearing ring 514 to reciprocate around the bend of the condenser coil 2 via the U-shaped support 512. At the same time, the first helical toothed gear 518 drives the bearing ring 514 to reciprocate and rotate on its own axis via the ring gear 517. When the bearing ring 514 revolves upward along the bend half a turn, the scraper ring 515 removes the remaining spray water outside the water film on the bend. When the bearing ring 514 rotates on its own axis, it discharges the removed spray water from the water ejector hole 516. When the bearing ring 514 revolves downward along the bend half a turn, the descaling unit 52 removes the dirt on the bend and discharges the removed dirt to the scale collection unit 53. The scale collection unit 53 collects the dirt and cleans it regularly.

[0037] It should be noted that a stepper motor 22 is provided on the tube sheet 21, which is used to drive the shaft 511 to rotate; The descaling unit 52 includes: A sliding cavity 521 is formed on the inner wall of the wiper ring 515, and two sets of piston channels 522 are symmetrically formed on the sliding cavity 521. A piston column 523 is slidably fitted inside the piston channel 522. A third elastic element 5231 is provided between one end of the piston column 523 and the inside of the piston channel 522. The other end of the piston column 523 extends into the sliding cavity 521 and is provided with a semi-circular scraping ring 524, which is adapted to the outer wall of the bend. An annular airbag 525 is disposed on the outer wall of the bearing ring 514 and is connected to the piston channel 522. The annular airbag 525 uses air pressure to drive the piston column 523 to bring the two sets of semi-circular scraping rings 524 inward and drive the two sets of semi-circular scraping rings 524 to combine into a circle on the outer wall of the bend. The U-shaped moving frame 526 is slidably disposed on the tube sheet 21 and elastically disposed on the tube sheet 21 by a first elastic member 5261. The shaft 511 is located inside the arc-shaped portion of the U-shaped moving frame 526. Stop block 527 is provided on the straight part of the U-shaped moving frame 526 and is used to abut against the tube plate 21 to limit the movement position of the U-shaped moving frame 526. The arc-shaped part of the U-shaped moving frame 526 is positioned on the axis of the shaft 511. The arc-shaped part of the U-shaped moving frame 526 compresses the annular airbag 525 and causes deformation. A transmission rack 528 is slidably disposed on the straight portion of the U-shaped moving frame 526 and elastically disposed on the straight portion of the U-shaped moving frame 526 by a second elastic member 5281. A semi-circular ratchet 529 is disposed on the U-shaped support 512 and is used to drive the transmission rack 528 to move in one direction.

[0038] It should be noted that the annular airbag 525 is made of hard rubber and is in a fully inflated state. The annular airbag 525 will not expand outward and deform again. The air pressure generated by the contraction of the annular airbag 525 is entirely applied to the piston column 523. It is worth mentioning that when the bearing ring 514 revolves downwards along the bend, the semi-circular ratchet 529 drives the transmission rack 528 to translate, causing the arc-shaped part of the U-shaped moving frame 526 to stop on the axis of the shaft 511. The arc-shaped part of the U-shaped moving frame 526 compresses the annular airbag 525, driving the semi-circular scraping ring 524 to work. After the bearing ring 514 revolves half a circle, the semi-circular ratchet 529 disengages from the transmission rack 528. The transmission rack 528 returns to its original position under the drive of the second elastic element 5281 and the first elastic element 5261. The U-shaped moving frame 526, under the drive of the first elastic element 5261... Upon retraction and reset, the arc-shaped portion of the U-shaped moving frame 526 disengages from the annular airbag 525, and the semi-circular scraper ring 524, driven by the third elastic element 5231, retracts to the interior of the water scraper ring 515 and resets, restoring the annular airbag 525 to its original state. When the bearing ring 514 revolves upward along the bend, the semi-circular ratchet 529 will not drive the transmission rack 528 to translate, the semi-circular scraper ring 524 does not work, and the water scraper ring 515 works. The bearing ring 514 reciprocates half a circle along the bend, causing the semi-circular scraper ring 524 and the water scraper ring 515 to work alternately, that is, to alternately remove scale and regulate the water film on the outer wall of the bend. It is also worth mentioning that the elastic force of the second elastic element 5281 is greater than that of the first elastic element 5261. That is, when the semi-circular ratchet 529 drives the transmission rack 528 to translate, the first elastic element 5261 deforms first, causing the transmission rack 528 to translate with the U-shaped moving frame 526. After the stop block 527 abuts against the tube plate 21 to limit the movement of the U-shaped moving frame 526, the transmission rack 528 continues to translate, which compresses the second elastic element 5281 to deform, so that the U-shaped moving frame 526 stays in the designated position. It should also be noted that when the bearing ring 514 revolves downward along the bend, the two sets of semi-circular scraping rings 524 combine into a circle on the outer wall of the bend to clean the dirt on the outer wall of the bend. At the same time, the spray water falls from top to bottom onto the bend. After the semi-circular scraping rings 524 scrape the outer wall of the bend, the spray water is replenished in time, so the bend will not dry-burn. The scale collection unit 53 includes: Scale collection box 531, two sets of scale collection boxes 531 are symmetrically arranged inside the box 1. Several sets of scale receiving plates 532 are arranged on one side of the scale collection box 531 at an upward angle. The scale receiving plates 532 are connected to the tube sheet 21 and are respectively located below the bend. Baffles 533 are respectively disposed on the scale receiving plate 532, and the scale receiving plate 532 is provided with a plurality of sets of drainage holes 534; The scale collection box 531 is provided with an overflow hole 535 and a sealing door 536.

[0039] It should be noted that when the scale collection box 531 accumulates a lot of dirt, the sealing door 536 should be opened and cleaned regularly.

[0040] In this embodiment, the bend tube processing component 5 and the condenser coil 2 work together to automatically and alternately descaling and adjusting the water film on the bend tube, cleaning the dirt on the outer wall of the bend tube, preventing scale corrosion on the outer wall of the bend tube, improving the service life of the condenser coil, and scraping off the excess spray water on the water film on the bend tube to increase the heat exchange effect. On the other hand, it can discharge the spray water scraped off on the bend tube to the surrounding area, avoiding excessive spray water accumulation at the connection between the bend tube and the tube sheet, which would result in a thick water film at the connection between the bend tube and the tube sheet, affecting the heat exchange effect. It also automatically collects the scraped dirt and purifies the spray water.

[0041] In detail, the spray system 3 sprays water to cool the fluid medium inside the condenser coil 2, the fan 4 discharges hot steam outwards, and the stepper motor 22 drives the shaft 511 to reciprocate half a turn. When the shaft 511 drives the bearing ring 514 to revolve downwards around the bend of the condenser coil 2 through the U-shaped support 512, the semi-circular ratchet 529 drives the transmission rack 528 to translate. The transmission rack 528 carries the U-shaped moving frame 526 to translate and compress the first elastic element 5261. When the stop block 527 abuts against the tube plate 21 to limit the movement of the U-shaped moving frame 526, the arc-shaped part of the U-shaped moving frame 526 stops on the axis of the shaft 511. The arc-shaped part of the U-shaped moving frame 526 compresses the annular airbag 525 to form a shape. As the transmission rack 528 continues to translate, the second elastic element 5281 deforms, causing the U-shaped moving frame 526 to stop at the designated position. The annular air bladder 525 contracts, using air pressure to drive the piston rod 523, which in turn pulls the two sets of semi-circular scraping rings 524 inward, causing them to combine into a circle on the outer wall of the bend, cleaning the dirt on the outer wall of the bend. At the same time, the semi-ring gear 5192 on the U-shaped stationary frame 5191 drives the second helical gear 519 to rotate, which in turn drives the first helical gear 518 to rotate. The first helical gear 518, through the ring gear 517, drives the bearing ring 514 to rotate, using centrifugal force to scrape the semi-circular scraping rings 524 off the outer wall of the bend. Water is discharged from the water-throwing hole 516 of the bearing ring 514. The intercepted dirt falls onto the scale-collecting plate 532 due to gravity. The dirt on the scale-collecting plate 532 is collected into the scale collection box 531 with the water flow and is cleaned periodically. Then, when the bearing ring 514 stops after rotating half a circle downward around the bend, the semi-circular ratchet 529 disengages from the transmission rack 528. The transmission rack 528 moves back to its original position under the drive of the second elastic element 5281 and the first elastic element 5261. The U-shaped moving frame 526 moves back to its original position under the drive of the first elastic element 5261. The arc-shaped part of the U-shaped moving frame 526 disengages from the annular airbag 525. The semi-circular scraping ring 524 moves back into the interior of the scraping ring 515 under the drive of the third elastic element 5231. Upon reset, the annular airbag 525 returns to its original state. When the shaft 511 drives the bearing ring 514 to revolve upwards half a circle around the bend of the condenser coil 2 via the U-shaped support 512, the scraper ring 515 scrapes away the remaining spray water outside the water film on the bend. At the same time, the semi-ring gear 5192 on the U-shaped stationary frame 5191 drives the bearing ring 514 to rotate via the second helical gear 519, the first helical gear 518, and the ring gear 517. Using centrifugal force, the water scraped off by the scraper ring 515 on the bend is discharged from the water-throwing hole 516 of the bearing ring 514. The bearing ring 514 stops after revolving upwards half a circle around the bend, and then revolves downwards half a circle again, repeating the cycle and automatically alternating to descaling and adjusting the water film on the bend.

[0042] Example 2 like Figure 12As shown, components that are the same as or corresponding to those in Embodiment 1 are referred to using the same reference numerals as in Embodiment 1. For simplicity, only the differences from Embodiment 1 are described below. The difference between Embodiment 2 and Embodiment 1 is as follows: Furthermore, such as Figure 12 As shown, the card holder 513 is provided with a relief groove 5131, which is located at the water-throwing hole 516 on the inner wall of the bearing ring 514. A brush 5132 is provided inside the relief groove 5131, which is used to clean the dirt at the water-throwing hole 516.

[0043] In this embodiment, the brush 5132 can clean the water-spinning holes 516 on the inner wall of the bearing ring 514 during its rotation, thus preventing dirt from clogging the water-spinning holes 516.

[0044] Example 3 like Figure 3 and Figures 13-16 As shown, components that are the same as or corresponding to those in Embodiment 1 are referred to using the same reference numerals as in Embodiment 1. For simplicity, only the differences from Embodiment 1 are described below. The difference between Embodiment 3 and Embodiment 1 is as follows: Furthermore, such as Figure 3 and Figures 13-16 As shown, it also includes a water collection component 6, which is located on the top of the tank 1 and is used to collect water droplets in the hot steam. The water collection component 6 includes a water collector 61 disposed on the top of the tank 1 and a water collection unit 62 disposed on the water collector 61. The water collector 61 includes: A bracket 611 is disposed on the top of the housing 1; C-shaped water-collecting sheet 612, several sets of the C-shaped water-collecting sheet 612 are horizontally arranged on the bracket 611, and the C-shaped water-collecting sheet 612 is formed by bending a corrugated plate; The water collection unit 62 includes: Water-enclosing plate 621, the water-enclosing plate 621 is disposed on both sides of the water collection surface groove at the lower part of the C-shaped water collecting plate 612; A collection box 622, and several sets of the collection boxes 622 are disposed on the impact surface of the lower part of the C-shaped water collecting plate 612; The drainage pipe 623 is inclined downward on the collection box 622 and is used to drain the water in the collection box 622 to the water collection surface groove at the lower part of the adjacent set of C-shaped water collection plates 612. A circulation inlet pipe 624 is provided on the bracket 611 and is connected to the water-enclosing plate 621 on one side of the C-shaped water-collecting plate 612. A circulation outlet pipe 625 is provided on the bracket 611 and is connected to the water-enclosing plate 621 on the other side of the C-shaped water-collecting plate 612. A water inlet pipe 626 is connected to the circulation inlet pipe 624, and a water outlet pipe 627 is connected to the circulation outlet pipe 625. One end of the water inlet pipe 626 and one end of the water outlet pipe 627 extend downward to the spray pool at the bottom of the tank 1.

[0045] It is worth mentioning that the point where the C-shaped water collecting plate 612 of the water collector 61 directly collides with the rising hot steam is the impact surface of the C-shaped water collecting plate 612, and the point where the C-shaped water collecting plate 612 does not directly collide with the hot steam and can temporarily store water droplets is the water collecting surface of the C-shaped water collecting plate 612.

[0046] It should be noted that an existing water pump is installed on the water distribution inlet pipe 626 to draw cooling water from the spray pool to the circulation inlet pipe 624. The circulation inlet pipe 624 then sends the cooling water to the water collection surface groove at the lower part of the C-shaped water collector 612. The water in the water collection surface groove flows from the circulation outlet pipe 625 and the water distribution outlet pipe 627 back to the spray pool, circulating repeatedly. This not only sends the water collected by the water collector 61 directly back to the spray pool, but also uses the circulating spray water to cool the C-shaped water collector 612, increasing the condensation effect of hot steam in the water collector 61.

[0047] In this embodiment, the water collection component 6 can, on the one hand, condense and collect water droplets carried by steam, increase the collision contact area between steam and water collector 61, guide water droplets to the water collection surface under the C-shaped water collector plate 612, temporarily store the collected water droplets, and reduce the situation where water droplets fall again and are carried away by steam again; on the other hand, the water collected by water collector 61 can be directly sent back to the spray water pool, and the circulating spray water is used to cool the C-shaped water collector plate 612, increasing the condensation effect of steam in water collector 61.

[0048] In detail, the rising steam comes into contact with the impact surface of the C-shaped water collector 612 of the water collector 61, and condenses into water droplets on the impact surface of the C-shaped water collector 612. Due to gravity, the water droplets flow into the collection box 622, and the water in the collection box 622 is guided to the water collection surface groove of the lower part of the adjacent set of C-shaped water collectors 612 through the diversion pipe 623. The water in the water collection surface groove flows from the circulation outlet pipe 625 and the distribution outlet pipe 627 to the spray water pool. The distribution inlet pipe 626 draws the cooling water in the spray water pool to the circulation inlet pipe 624, and the circulation inlet pipe 624 then sends the cooling water to the water collection surface groove of the lower part of the C-shaped water collector 612. The cycle repeats, not only sending the water collected by the water collector 61 directly back to the spray water pool, but also using the circulating spray water to cool the C-shaped water collector 612.
