Description

Technical Field

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

[0002] Evaporative condensers are highly efficient and energy-saving heat exchange devices that combine the principles of water cooling and air cooling. They enhance the condensation process by utilizing the latent heat of vaporization of water and are widely used in refrigeration, air conditioning, chemical, and power industries.

[0003] While existing evaporative condensers can improve energy efficiency and alleviate high-temperature shutdown problems through water evaporation, their core drawback lies in the fact that the sprayed circulating water contains calcium and magnesium ions and acidic carbonates. Under the action of high-temperature and high-pressure refrigerant (gas temperature reaching above 80°C), carbonate deposits are easily formed when the water flows through the metal coils, causing the scaling rate to increase significantly with rising temperature. At the same time, dissolved oxygen in the water can trigger metal corrosion, forming oxides such as rust. These corrosion and scaling problems are superimposed, which not only cause a continuous decline in heat exchange efficiency and increased energy consumption, but also cause safety hazards such as pipe blockage and localized overheating due to damage to the metal structure and accumulation of dirt, ultimately threatening the safe and stable operation of the refrigeration system.

[0004] Therefore, it is necessary to design a scaling-inhibiting evaporative condenser to solve the above problems. Summary of the Invention

[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing a scale-inhibiting evaporative condenser.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: A scaling-inhibiting evaporative condenser includes a housing with adjustable air valves on both sides. Two partitions are fixed inside the housing, each with a baffle plate. A gap exists between the two baffle plates, and each baffle plate has an opening at its top.

Vertical rods are fixed at the four corners of the top surface of the water tank, and the four vertical rods are connected to the installation frame by tension springs. A cleaning component is provided on the installation frame for cleaning the filter screen.

[0011] As a preferred embodiment of the present invention, the cleaning assembly includes two guide rods, which are respectively fixed on both sides of the top surface of the mounting frame. A movable plate is slidably mounted on both guide rods. A scraper is provided on the bottom surface of the movable plate, and a push rod is fixed on the side of the movable plate, with the push rod facing the cover plate.

[0012] As a preferred embodiment of the present invention, a limiting plate is fixed inside the water tank, and a slot adapted to the limiting plate is provided on the mounting frame, the slot being engaged with the limiting plate.

[0013] As a preferred embodiment of the present invention, a fixing plate is fixed to the side of the cover plate, and an inclined surface is provided on the fixing plate. A sliding sleeve is slidably sleeved on the push rod, and the sliding sleeve is connected to the moving plate by a second spring. A fixing rod is fixed on the sliding sleeve and is arranged in a vertical direction. A pressing assembly is provided on the outer shell for pressing the cover plate. The pressing assembly consists of a pressing structure and a releasing structure. The pressing structure is located on the side of the outer shell and acts on the fixing plate. The releasing structure is located inside the outer shell.

[0014] As a preferred embodiment of the present invention, the clamping structure includes a first sealing cylinder, which is fixed to the side of the outer shell. A first sliding plug is slidably connected inside the first sealing cylinder. A first moving rod is fixed on the first sliding plug, and the first moving rod is positioned directly opposite the fixed plate. The first sliding plug and the first sealing cylinder are connected by a third spring.

[0015] As a preferred embodiment of the present invention, the release structure includes a second sealing cylinder, which is fixed inside the outer shell. A second sliding plug is slidably connected inside the second sealing cylinder. A second moving rod is fixed on the second sliding plug. One end of the second moving rod away from the second sliding plug extends to the outside of the second sealing cylinder and is fixed with an extension rod. The extension rod is positioned opposite the fixed rod. The second sealing cylinder and the first sealing cylinder are connected by a connecting pipe.

[0016] The present invention has the following beneficial effects: 1. Traditional single-stage evaporative condensers have high metal surface temperatures and a high risk of scaling. This invention sets up a dry coil condenser and a wet coil condenser to separate the high-risk temperature zone. The refrigerant temperature is first reduced by the dry coil condenser before entering the wet coil condenser. At this time, the refrigerant temperature drops to 40℃~45℃, which makes it easier to clean scale. In addition, the outside of the wet coil is impacted and disturbed by the mixed airflow, which can improve the heat transfer coefficient and use the shear force of the water flow to slow down the deposition of dirt. 2. The wet coil condenser and the two dry coil condensers are arranged horizontally. Compared with the existing patented vertical arrangement, this can prevent the humid hot air that has passed through the wet coil condenser from corroding the fins when it passes through the dry coil condenser, thus extending the service life of the equipment. 3. The wet coil condenser is designed to move up and down. When cleaning scale, after emptying the water tank, add detergent and pull the second water collector to separate it from the wet coil condenser. Then, start the linear actuator to immerse the wet coil condenser in the detergent. Compared with the traditional spraying method, this extends the contact time between the detergent and the scale. The detergent can fully penetrate the scale, break down its structure, make the scale soft and easy to fall off, and act evenly on all parts of the wet coil condenser, significantly improving the scale removal effect and removing scale more thoroughly. 4. The water tank is equipped with a sliding mounting frame with a filter screen. When cleaning the wet coil condenser, the wet coil condenser moves down and presses down on the filter screen, and the scale falls off onto the filter screen. After cleaning, the wet coil condenser moves up, and the mounting frame and filter screen are reset under the action of the tension spring, so as to separate the scale from the cleaning agent, avoid contaminating the cleaning agent, and facilitate unified treatment of scale. 5. The design of the clamping assembly ensures the sealing between the cover plate and the outer shell when the device is working normally. The clamping structure uses a third spring to cause the first sliding plug to drive the first moving rod to press the inclined surface of the fixed plate and clamp the cover plate. When the moving plate approaches the drain port, the fixed rod pushes the extension rod to cause the second sliding plug to extract the gas in the first sealing cylinder. The first sliding plug moves upward and causes the first moving rod to separate from the fixed plate, automatically releasing the clamping of the cover plate. The movable characteristic of the sliding sleeve avoids interference between the push rod and the extension rod. Attached Figure Description

[0019] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0020] Reference Figure 1-9 A scaling-inhibiting evaporative condenser includes a housing 1. Adjustable air valves 11 are provided on both sides of the housing 1. The adjustable air valves 11 can adjust the air intake volume. The specific structure and working principle of the adjustable air valves 11 are existing technology, implemented using conventional methods, and are not shown in the figure or described in detail here. An axial flow fan is installed on the top of the housing 1 to guide airflow. A door is provided on the side of the housing 1, with an installation opening on the door. A flip-top door is provided on the door, and the flip-top door is positioned directly opposite the installation opening. A drain port 12 is provided on the side of the housing 1. A rotatable cover plate 13 is provided on the side of the shell 1, and the cover plate 13 is positioned directly opposite the drain outlet 12. In the initial state, the cover plate 13 is closed on the drain outlet 12, which can block the drain outlet 12 and prevent moisture or solid impurities in the shell 1 from leaking out. A detachable collection container 14 is provided on the side of the shell 1, and the collection container 14 is located below the drain outlet 12. The collection container 14 is used to collect the scale that falls from the drain outlet 12. The collection container 14 is detachably set on the side of the shell 1, which makes it convenient for staff to clean the scale in the collection container 14.

[0021] The outer casing 1 has two fixed partitions 2 inside, each with a baffle plate 3. The two partitions 2 are arranged horizontally, and the two baffle plates 3 are arranged vertically, with a gap between them. Each baffle plate 3 has an opening 31 at its top. A dry coil condenser 4 is installed on each of the two partitions 2, and a wet coil condenser 52 is placed between the two baffle plates 3. The wet coil condenser 52 is fixedly installed on the baffle plate 3 by a bracket 51. The outer casing 1 also has a first water collector 71, a second water collector 72, and a spray pipe assembly 8. The spray pipe assembly 8 is located above the wet coil condenser 52, and the first water collector 71 is located above the spray pipe assembly 8. The second water collector 72 is slidably disposed in the outer casing 1. The outer casing 1 has two opposite slide rails 721 fixed inside, each with a slider 722 slidably disposed on it. The second water collector 72 is fixed between the two sliders 722. 2. An installation port is set directly opposite the door. By setting a slide rail 721 and a slider 722, the second water collector 72 can be moved. When the device is working, the second water collector 72 is located below the wet coil condenser 52. When it is necessary to clean the scale on the wet coil condenser 52, the operator pulls the second water collector 72 until the second water collector 72 is misaligned with the wet coil condenser 52 to avoid the second water collector 72 blocking the downward movement of the wet coil condenser 52. A water tank 91 is set at the bottom of the inner shell 1. A water pump is installed inside the shell 1. When the water pump is running, it draws water from the water tank 91 and pumps the water flow into the spray pipe assembly 8, so that the water flow is sprayed out through the spray pipe assembly 8. A drain pipe 911 is connected to the water tank 91. The end of the drain pipe 911 away from the water tank 91 extends to the outside of the shell 1. A valve is installed on the drain pipe 911. When draining, the operator opens the valve to let the water in the water tank 91 flow out through the drain pipe 911.

[0022] In operation, the evaporative condenser proposed in this invention first introduces two dry coil condensers 4, where the high-temperature superheated gaseous refrigerant discharged from the compressor flows within them. Outside air undergoes forced convection heat exchange with the high-temperature gaseous refrigerant through the tube-fin structure, rapidly reducing the refrigerant temperature and gradually approaching the gas-liquid two-phase region, completing the initial pre-cooling process. Subsequently, the refrigerant enters a wet coil condenser 52 connected in series with the two dry coil condensers 4. The wet coil condenser 52 uses corrosion-resistant stainless steel tubes with a large tube spacing and a hydrophilic coating. When the spray pipe assembly 8 evenly sprays circulating water onto the surface of the wet coil, the hydrophilic coating enhances the adhesion of the water film, causing it to spread evenly on the coil surface to form a continuous heat exchange layer. At this point, the refrigerant and water film exchange heat through the tube walls. Heat exchange occurs when the water film absorbs heat from the refrigerant and partially evaporates, utilizing the latent heat of vaporization to achieve efficient condensation, ultimately converting the refrigerant completely into a liquid state. During this process, the first water collector 71 intercepts water droplets carried in the airflow through a special structure, preventing droplets from being drawn into the axial fan and causing equipment damage, while also reducing circulating water loss. To prevent water droplets sprayed from the wet coil condenser 52 area from escaping to the dry coil condenser 4 areas on both sides due to airflow disturbance and causing metal corrosion, a baffle plate 3 is added between the two coils to form physical isolation. Furthermore, through two adjustable air valves, the flow ratio of the two airflows can be dynamically adjusted according to actual operating conditions, ensuring the precooling effect of the dry coil while optimizing the evaporation efficiency of the wet coil area, ultimately achieving synergistic optimization of efficient refrigerant condensation and stable system operation.

[0023] Each dry coil condenser 4 is connected to a first mounting pipe 41, and each wet coil condenser 52 is connected to a second mounting pipe 53. Two connecting pipes 54 are connected to the second mounting pipe 53. The two first mounting pipes 41 are respectively connected to the two connecting pipes 54. The first mounting pipes 41 and the connecting pipes 54 are connected by a connecting assembly, which includes a first collar 411, a second collar 413, and an insert tube 412. The first collar 411 is fixedly fitted onto the end of the first mounting pipe 41 away from the dry coil condenser 4. The insert tube 412 is fixedly fitted into the opening of the first mounting pipe 41. The second collar 413 is fixedly fitted onto the insert tube 412. The first collar 411 and the second collar 413 are connected by a first spring 414. Figure 5As shown, in the initial state, the connecting pipe 54 is in a state of compressing the second sleeve ring 413. At this time, the second sleeve ring 413 compresses the first spring 414. Under the elastic force of the first spring 414, the second sleeve ring 413 presses the connecting pipe 54 tightly, and the insertion tube 412 is inserted into the connecting pipe 54. The outer surface of the insertion tube 412 is in contact with the inner wall of the connecting pipe 54. Under these circumstances, the first mounting tube 41 and the connecting pipe 54 are in a connected state, which connects the dry coil condenser 4 and the wet coil condenser 52. In addition, both the pipe opening of the connecting pipe 54 and the bottom surface of the second sleeve ring 413 are provided with sealing rings. When the second sleeve ring 413 presses the connecting pipe 54 tightly, the two sealing rings are in contact with each other, which can seal the connection between the connecting pipe 54 and the first mounting tube 41 and prevent leakage.

[0024] A linear actuator 6 is installed inside the outer casing 1. The linear actuator 6 has a vertically movable lifting seat 61, which is fixedly connected to the bracket 51. When the linear actuator 6 operates, the lifting seat 61 drives the bracket 51 to move up and down, thereby moving the wet coil condenser 52 up and down. For evaporative condensers, during operation, workers need to regularly clean the scale adhering to the surface of the condenser tubes. In existing technology, workers generally spray a pre-prepared special cleaning agent onto the condenser tubes, allowing the cleaning agent to react with the scale and remove it. However, this method has limited contact time between the cleaning agent and the pipes because the cleaning agent will naturally drip off under gravity, thus limiting the cleaning effect. In this invention, a movable wet coil condenser 52 is designed. When it is necessary to clean the scale attached to the wet coil condenser 52, the operator first empties the water in the water tank 91, then injects the prepared cleaning agent into the water tank 91, and then pulls the second water collector 72 to separate the second water collector 72 from the wet coil condenser 52, so as to prevent the second water collector 72 from obstructing the wet coil condenser 52 from entering the water tank 91. Furthermore, the operator activates the linear actuator 6. When the linear actuator 6 is running, it can drive the wet coil condenser 52 to move downward until the wet coil condenser 52 is immersed in the cleaning agent in the water tank 91. Compared with the traditional spraying method, this improved solution allows the wet coil condenser 52 to be soaked in the cleaning agent for a long time, extending the contact time between the cleaning agent and the scale. During the long soaking process, the cleaning agent has enough time to penetrate into the limescale and react chemically with the various components in the limescale, gradually breaking down the structure of the limescale and making it soft and easy to remove. At the same time, the soaking method can also ensure that the cleaning agent is evenly applied to all parts of the wet coil condenser 52, effectively cleaning both the surface and hidden corners, thus significantly improving the descaling effect and more thoroughly removing limescale from the pipe surface.

[0025] An installation frame 92 is slidably mounted inside the water tank 91. A filter screen 921 is fixed on the installation frame 92, and the top surface of the installation frame 92 is flush with the filter screen 921. A limit plate 912 is fixed inside the water tank 91. A slot is opened on the installation frame 92 to fit the limit plate 912. The slot engages with the limit plate 912. During the movement of the installation frame 92, the limit plate 912 and the slot provide a limit, ensuring the stability of the installation frame 92 and preventing it from shaking. Vertical rods 93 are fixed at the four corners of the top surface of the water tank 91. Each of the four vertical rods 93 is connected to the installation frame 92 by a tension spring 94. In the initial state, under the action of the four tension springs 94, the installation frame 92 is located at the top of the water tank 91. When cleaning the wet coil condenser 52, the wet coil condenser 52 moves downward and enters the water tank 91. At this time, the bracket 51 presses down on the filter screen 921, causing the filter screen 921 and the mounting frame 92 to move downward. When the wet coil condenser 52 is immersed in the cleaning agent, large pieces of scale attached to the pipe surface will fall off the pipe under the action of the cleaning agent and eventually fall onto the filter screen 921. After cleaning, the linear actuator 6 drives the bracket 51 to move upward, causing the wet coil condenser 52 to move out of the water tank 91. At this time, the mounting frame 92 and the filter screen 921 will move upward and reset under the action of four tension springs 94. The design of the filter screen 921 can separate the scale from the cleaning agent, avoid scale contamination of the cleaning agent, and facilitate unified treatment of scale.

[0026] A cleaning assembly is provided on the mounting frame 92 for cleaning the filter screen 921. The cleaning assembly includes two guide rods 101, which are fixed to both sides of the top surface of the mounting frame 92. A movable plate 102 is slidably mounted on both guide rods 101. A scraper 1021 is provided on the bottom surface of the movable plate 102. During the movement of the movable plate 102, the scraper 1021 is in contact with the surface of the filter screen 921, which allows the scraper 1021 to push away the scale on the filter screen 921. A push rod 103 is fixed to the side of the movable plate 102, and the push rod 103 is positioned opposite the cover plate 13. When it is necessary to clean the scale on the filter screen 921, the worker... The operator can push the movable plate 102 to move it from one end of the mounting frame 92 to the other end. During this process, the scraper 1021 on the movable plate 102 can push the scale on the filter screen 921 and push it to a position close to the drain port 12. When the movable plate 102 is close to the drain port 12, the push rod 103 will contact the cover plate 13 and push the cover plate 13 to rotate. When the cover plate 13 rotates, it will no longer block the drain port 12. Furthermore, the movable plate 102 and the scraper 1021 can push the scale out through the drain port 12. Finally, the scale will fall into the collection container 14, realizing the rapid cleaning of the filter screen 921.

[0027] A fixing plate 131 is fixed to the side of the cover plate 13. The fixing plate 131 has an inclined surface. A sliding sleeve 104 is slidably fitted onto the push rod 103, and the sliding sleeve 104 is connected to the moving plate 102 via a second spring 105. A fixing rod 1041 is fixed to the sliding sleeve 104, and the fixing rod 1041 is arranged vertically. A pressing assembly is provided on the outer shell 1 to press the cover plate 13. The pressing assembly consists of a pressing structure and a releasing structure. The pressing structure is located on the side of the outer shell 1 and acts on the fixing plate 131. The releasing structure is located inside the outer shell 1. To ensure the sealing between the cover plate 13 and the outer shell 1 during normal operation, this invention designs a pressing assembly. In the initial state, the cover plate 13 is closed on the outer shell 1, at which time the cover plate 13 blocks the drain outlet 12. The pressing structure can... The cover plate 13 is pressed down, so that the cover plate 13 applies pressure to the outer shell 1, thereby improving the sealing between the cover plate 13 and the outer shell 1 and preventing liquid leakage from the drain port 12. The pressing structure includes a first sealing cylinder 111, which is fixed to the side of the outer shell 1. The first sealing cylinder 111 is slidably connected to a first sliding plug 112 inside the first sealing cylinder 111. A first moving rod 113 is fixed on the first sliding plug 112 and is positioned directly opposite the fixing plate 131. The first sliding plug 112 and the first sealing cylinder 111 are connected by a third spring 114. Under the elastic force of the third spring 114, the first sliding plug 112 is located at the bottom end of the first sealing cylinder 111. At this time, the first moving rod 113 will squeeze the inclined surface of the fixing plate 131, thereby pressing the cover plate 13 onto the outer shell 1.

[0028] The release structure includes a second sealing cylinder 115, which is fixed inside the outer casing 1. A second sliding plug 116 is slidably connected inside the second sealing cylinder 115. A second moving rod 117 is fixed to the second sliding plug 116. One end of the second moving rod 117, away from the second sliding plug 116, extends to the outside of the second sealing cylinder 115 and is fixed with an extension rod 1171. The extension rod 1171 is positioned opposite the fixed rod 1041. The second sealing cylinder 115 and the first sealing cylinder 111 are connected by a... The connecting pipes are connected. During the process of the moving plate 102 approaching the drain outlet 12, before the push rod 103 contacts the cover plate 13, the fixed rod 1041 first contacts the extension rod 1171. At this time, the resistance of the extension rod 1171 to the fixed rod 1041 cannot overcome the elastic force applied to the sliding sleeve 104 by the second spring 105. This allows the fixed rod 1041 to push the extension rod 1171, thereby causing the extension rod 1171 to drive the second moving rod 117 to move. When the second moving rod 117 moves, it can carry... The second sliding plug 116 moves, and when it moves, it can extract the gas in the first sealing cylinder 111 through the connecting pipe. When the gas in the first sealing cylinder 111 is extracted, the first sliding plug 112 will move upward under the action of pressure difference, and drive the first moving rod 113 to move upward, so that the first moving rod 113 separates from the fixed plate 131. In this case, the first moving rod 113 no longer presses against the cover plate 13, so as to avoid the first moving rod 113 from hindering the smooth flipping of the cover plate 13. It should be noted that when the second sliding plug 116 moves to the limit position, the extension rod 1171 can no longer move. At this time, the fixed rod 1041 and the sliding sleeve 104 can no longer move, but the moving plate 102 and the push rod 103 still move. At this time, the sliding sleeve 104 will slide on the push rod 103, and relative movement will occur between it and the push rod 103, and squeeze the second spring 105. The movable characteristic of the sliding sleeve 104 can avoid the phenomenon of motion interference between the push rod 103 and the extension rod 1171.
