Description

Technical Field

[0001] This invention relates to the field of evaporative condenser technology, and more particularly to an evaporative condenser with a power regulating mechanism. Background Technology

[0002] Evaporative condensers are core heat exchange equipment in the fields of refrigeration, chemical industry, HVAC, and industrial waste heat recovery. Their core working principle is as follows: sprayed water forms a uniform water film on the surface of the heat exchange coil. The water film absorbs heat and evaporates rapidly. At the same time, in conjunction with the forced convection of the fan, the gaseous medium is rapidly condensed, completing the system's heat exchange cycle.

[0003] Patent CN114234492A discloses an evaporative condenser, comprising a central condenser section located in the middle of the cooling air channel cross-section and an outer condenser section located at the edge of the cooling air channel cross-section. In the direction of cooling airflow, the cooling efficiency per unit cross-section of the central condenser section is at least greater than the cooling efficiency per unit cross-section of the outer condenser section. In this evaporative condenser, the cooling effect can be matched to the airflow distribution pattern to ensure that the cooling effect in the middle and at the edge is similar. This evaporative condenser effectively solves the problem of wasted condenser piping or refrigerant.

[0004] However, the air passage of traditional equipment has a fixed structure and cannot adjust the flow area according to the steam output. Under high load, the steam is not discharged smoothly, the internal pressure rises, the heat exchange efficiency decreases, and even problems such as steam backflow and splashing water overflow occur. Under low load, the passage is too wide, the ineffective air volume of the fan increases, and the energy consumption increases significantly. Summary of the Invention

[0005] The purpose of this invention is to address the shortcomings of the prior art by proposing an evaporative condenser with a power regulation mechanism.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: An evaporative condenser with a power regulating mechanism includes: a condenser housing, a condenser tube assembly, and a water collection tank installed at the bottom of the condenser housing, wherein the top wall of the condenser housing is provided with a spraying assembly for downward spraying. An air guiding component is provided between the spraying component and the condenser pipe device. The air guiding component includes two side plates, a sliding plate and multiple elastic elements. The two side plates are symmetrically fixedly connected to both sides of the water collection tank. The sliding plate is an inverted U-shaped plate and is slidably connected to the side plates on both sides. The four elastic elements are fixedly connected to the four corners above the sliding plate and are fixedly connected to the top wall of the condenser box. Multiple first air vents are equally spaced on both side plates, and multiple second air vents are symmetrically opened on both sides of the sliding plate, with the first air vents and the second air vents being staggered. A flow divider is provided on the top of the sliding plate, and the flow divider is located below the spraying assembly.

[0007] Preferably, the spraying assembly includes a liquid guide pipe, multiple connecting pipes, and multiple spraying elements. The multiple connecting pipes are vertically fixedly connected to the side of the liquid guide pipe and are arranged parallel to the diverter plate. The multiple spraying elements are equidistantly fixedly connected to the bottom of the connecting pipes and pass through the diverter plate.

[0008] Preferably, the sliding plate has multiple strip-shaped mounting openings at equal intervals, the diverter plate is fitted inside the mounting openings, the bottom of the diverter plate is arc-shaped, and multiple diverting holes are equally spaced on the diverter plate. The diverter plate has a sliding opening at equal intervals in the middle, and the spraying component passes through the sliding opening.

[0009] Preferably, the spraying component includes a diverter pipe, a telescopic pipe, and multiple nozzles. The diverter pipe is fixedly connected to the bottom of the liquid guide pipe, the upper end of the telescopic pipe is rotatably connected to the bottom of the diverter pipe, and the multiple nozzles are symmetrically fixedly connected to both sides of the telescopic pipe.

[0010] Preferably, the middle part of the diversion pipe is a variable diameter pipe with a small upper and lower diameter and a large middle diameter, and the variable diameter part is inclined. The variable diameter part below the diversion pipe has multiple spray nozzles in a ring shape, and the spray nozzles are oriented towards the diversion plate.

[0011] Preferably, the diverter tube is provided with a rotating component inside, which is used to drive the telescopic tube to rotate.

[0012] Preferably, the rotating assembly includes a rotating ring, a fixed frame, a connecting frame, and multiple drive plates. A rotating groove is provided inside the diverter pipe. The rotating ring is rotatably disposed inside the rotating groove. The multiple drive plates are fixedly connected in a ring shape to the inner side of the rotating ring. The connecting frame is fixedly connected between the rotating rings. The fixed frame is an inverted T-frame, with its upper end fixedly connected to the middle of the rotating ring and its lower end fixedly connected to the inside of the telescopic pipe.

[0013] Preferably, two exhaust fans are provided above the condenser box, and two symmetrical side air guide spaces are formed between the two side plates and the two sides of the inner wall of the condenser box. An upper air guide space is formed between the upper part of the sliding plate and the top wall of the condenser box, and the exhaust fans are connected to the upper air guide space.

[0014] Preferably, a guide cover is fixedly connected to the side of the second air inlet away from the first air inlet. The upper surface of the guide cover is arc-shaped, and the lower part is configured as an opening communicating with the second air inlet.

[0015] Preferably, multiple sliders are symmetrically fixedly connected to both sides of the sliding plate, and strip grooves are symmetrically opened inside the side plate near the sliding plate, with the sliders slidably disposed inside the strip grooves.

[0016] Compared with the prior art, the beneficial effects of the present invention are: 1. The staggered structure of the first and second air inlets plays a role in rectifying the airflow. After the steam flows out of the condensation zone, it passes through the first and second air inlets in sequence, and the flow direction is gradually sorted out, so that large-scale turbulence and local deflection will not be formed in the box. 2. The fine water mist generated by the spray moves downward under the influence of gravity, while the steam flows upward. The two layers of staggered shielding structure form a physical barrier, which greatly reduces the probability of liquid water mist entering the exhaust channel with the airflow. On the one hand, it reduces the loss of cooling water with the exhaust and improves the water recycling rate. On the other hand, it prevents water mist from entering the fan and air duct, reducing the problems of condensation, water accumulation and corrosion on the inner wall of the air duct. 3. The liquid guide pipe and connecting pipe evenly distribute the water flow to ensure that the water inlet pressure of each spray component is consistent. The variable diameter diversion pipe changes the water flow velocity based on the fluid characteristics, so that the spray speed can be adaptively adjusted with the water supply flow rate. This solves the problems of fixed spray flow velocity and single spray range in traditional spraying. At the same time, it outputs a stable impact force downward to provide power for the adjustment of the air guide component. 4. The diverter plate disperses the concentrated point-like water flow from the spray nozzles, transforming it into a uniform surface water flow. This evenly distributes the water flow impact force to the entire sliding plate, preventing the sliding plate from jamming or tilting due to single-point force. The arc-shaped plate surface and the diverter holes provide secondary water distribution, further optimizing the spray distribution effect. This solves the problems of uneven force on the concentrated water flow, obstructed movement of the sliding components, and secondary deflection of the spray water flow. Attached Figure Description

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

[0020] The terms used in this invention, such as "upper," "lower," "left," "right," "middle," and "one," are merely for clarity of description and are not intended to limit the scope of the invention. Any changes or adjustments to their relative relationships, without substantially altering the technical content, should also be considered within the scope of the invention.

[0021] Reference Figures 1-9 An evaporative condenser with a power regulating mechanism includes: a condenser housing 1, a condenser tube assembly 2, and a water collection tank 3 installed at the bottom of the condenser housing 1. The top wall of the condenser housing 1 is provided with a spraying assembly 4 for downward spraying. An air guiding component 5 is provided between the spraying component 4 and the condenser pipe device 2. The air guiding component 5 includes two side plates 51, a sliding plate 52 and multiple elastic elements 53. The two side plates 51 are symmetrically fixedly connected to both sides of the water collection tank 3. The sliding plate 52 is an inverted U-shaped plate and is slidably connected to the side plates 51 on both sides. The four elastic elements 53 are fixedly connected to the four corners above the sliding plate 52 and are fixedly connected to the top wall of the condenser box 1. Multiple first air vents 8 are equally spaced on both side plates 51, and multiple second air vents 9 are symmetrically opened on both sides of the sliding plate 52. The first air vents 8 and the second air vents 9 are arranged alternately. A diversion plate 6 is provided on the top of the sliding plate 52. The diversion plate 6 is located below the spraying component 4. The diversion plate 6 diverts the liquid sprayed by the spraying component 4 and drives the sliding plate 52 to move downward.

[0022] In the embodiment of the above technical solution, the condenser box 1 is a sealed metal cavity with a fan installation position at the top and a spray assembly 4. The middle and lower part houses the condenser tube device 2, which is composed of multiple heat exchange pipes. The high-temperature gaseous medium to be condensed is transported inside the pipes, and the outside of the pipes is in direct contact with the sprayed water and flowing air. After the equipment is started, the high-temperature gaseous medium is continuously introduced into the condenser tube. The cooling water sprayed by the spray assembly 4 falls on the outer wall of the pipe to form a continuous water film. The water film absorbs heat and evaporates to generate steam, and the condenser tube continuously completes heat exchange.

[0023] The water collection tank 3 is mainly used to collect the cooling water that falls after heat exchange. At the same time, it serves as the bottom fixing base for the two side plates 51 in the air guide assembly 5, preventing the side plates 51 from shaking or shifting, and ensuring the accurate alignment of the air guide port.

[0024] The first air inlets 8 are evenly distributed on the side plate 51 and remain in a fixed position, while the second air inlets 9 are distributed on both sides of the sliding plate 52 and move vertically in a straight line with the sliding plate 52 as a whole. When the equipment is not started, the spraying component 4 has no water output, the diverter plate 6 is not subjected to downward impact force, and the sliding plate 52 is pulled up to the vertical maximum limit position under the pulling force of the four sets of elastic elements 53. At this time, the second air guide port 9 stays at a high position with the sliding plate 52, completely intersecting and blocking the fixed first air guide port 8. The overlapping area of ​​the two ports is small, and the air guide channel is small.

[0025] As the system power is gradually increased, the cooling water supply flow rate and spray velocity continue to increase. The downward pressure of the water flow impacting the diverter plate 6 gradually exceeds the tension of the elastic element 53. The sliding plate 52 slides down at a constant speed, and the second air guide port 9 moves down synchronously with the sliding plate 52. The two originally intersecting ports begin to gradually align, the overlapping area continues to increase, and the air guide flow cross section changes from small to large. During this stage, the steam output increases synchronously with the spray intensity. The gradually increasing steam flows through the continuously expanding flow channel, and the airflow rate continues to increase.

[0026] When the equipment is operating at full load, the spray flow rate reaches its peak, the pressure on the diverter plate 6 is at its maximum, the sliding plate 52 moves down to its lowest vertical limit position and remains stable, the elastic element 53 is stretched to its maximum deformation state, the second air guide port 9 moves down to its lowest position, and the overlap area with the first air guide port 8 reaches its maximum value, the air guide channel is fully open, and the flow capacity is at its strongest. At this time, the water film in the condenser tube evaporates violently, a large amount of steam is generated in the box, the airflow velocity is fast, and the large cross-section channel can ensure that high-density steam passes through quickly without steam congestion or airflow backflow.

[0027] The staggered structure of the first air inlet 8 and the second air inlet 9 straightens the airflow. After the steam flows out of the condensation zone, it passes through the first and second air inlets 9 in sequence, and the flow direction is gradually straightened. Large-scale turbulence and local deflection will not form in the box.

[0028] The fine water mist generated by the spray moves downwards under the influence of gravity, while the steam flows upwards. The two-layered staggered shielding structure forms a physical barrier, which greatly reduces the probability of liquid water mist entering the exhaust duct with the airflow. On the one hand, it reduces the loss of cooling water with the exhaust and improves the water recycling rate. On the other hand, it prevents water mist from entering the fan and air duct, reducing condensation, water accumulation, and corrosion problems on the inner wall of the air duct.

[0029] When combined with the guide cover 11 to form a composite airflow guiding system, the airflow direction remains stable during the adjustment of the air inlet, and there will be no airflow turbulence due to the opening and closing of the channel, and the operating noise of the equipment will also be reduced.

[0030] The preferred technical solution in this embodiment is: Reference Figures 5-8 The spraying assembly 4 includes a liquid guide pipe 41, multiple connecting pipes 42 and multiple spraying elements 43. The multiple connecting pipes 42 are vertically fixedly connected to the side of the liquid guide pipe 41 and are arranged parallel to the diverter plate 6. The multiple spraying elements 43 are equidistantly fixedly connected to the bottom of the connecting pipes 42. The spraying component 43 includes a diversion pipe 431, a telescopic pipe 432, and multiple nozzles 433. The diversion pipe 431 is fixedly connected to the bottom of the liquid guide pipe 41. The upper end of the telescopic pipe 432 is rotatably connected to the bottom of the diversion pipe 431. The multiple nozzles 433 are symmetrically fixedly connected to both sides of the telescopic pipe 432. Cooling water first enters the liquid guide pipe 41, then is distributed to each connecting pipe 42, and finally flows into the corresponding spray element 43. After the water flows into the variable diameter distribution pipe 431, part of it impacts the internal drive plate 74, which drives the rotating ring 71, telescopic pipe 432 and nozzle 433 to rotate continuously, spraying cooling water onto the condenser pipe below. The other part of the water flows out from the spray port on the side of the distribution pipe 431 and falls vertically onto the distribution plate 6 below. When the water supply flow rate increases, the spray flow rate increases and the speed of the nozzle 433 increases. When the flow rate decreases, the spray flow rate and speed decrease simultaneously.

[0031] The liquid guide pipe 41 and connecting pipe 42 evenly distribute the water flow, ensuring consistent inlet pressure for each spray element 43. The variable diameter diverter pipe 431 changes the water flow velocity based on fluid characteristics, enabling adaptive adjustment of the spray speed according to the water supply flow. This solves the problems of fixed spray velocity and limited spray range in traditional spraying systems, while simultaneously outputting a stable downward impact force to power the adjustment of the air guide assembly 5.

[0032] Reference Figure 5 and Figure 6 The sliding plate 52 has multiple strip-shaped mounting openings at equal intervals. The diverter plate 6 is fitted inside the mounting opening. The bottom of the diverter plate 6 is arc-shaped, and multiple diverter holes are equally spaced on the diverter plate 6. The middle part of the diverter plate 6 has a sliding opening at equal intervals, and the spraying component 43 passes through the sliding opening. The middle part of the diversion pipe 431 is a variable diameter pipe with a small upper and lower diameter and a large middle diameter, and the variable diameter part is inclined. Multiple spray nozzles are arranged in a ring shape on the variable diameter part below the diversion pipe 431, and the spray nozzles are arranged facing the diversion plate 6.

[0033] During operation, the diversion plate 6 continuously receives the water flow from the spray nozzles 43. The water flow impact force acts on the plate from top to bottom. When the spray velocity increases and the impact force increases, the diversion plate 6 is lifted by the force, causing the sliding plate 52 below to move downwards synchronously. When the spray velocity decreases and the impact force weakens, the diversion plate 6 returns to its original position upwards along with the sliding plate 52. Throughout the entire up-and-down sliding process of the sliding plate 52, the connecting pipe 42 always moves within the sliding port, limiting the horizontal displacement of the diversion plate 6 and ensuring that the force direction is always vertically downwards.

[0034] The diverter plate 6 disperses the concentrated point-like water flow from the spray nozzles 43, transforming it into a uniform surface water flow. This evenly distributes the water flow impact force to the entire sliding plate 52, preventing the sliding plate 52 from jamming or tilting due to single-point force. The arc-shaped plate surface and the diverter holes provide secondary water distribution, further optimizing the spray distribution effect. This solves the problems of uneven force on the concentrated water flow, obstructed movement of the sliding components, and secondary deflection of the spray water flow.

[0035] Reference Figure 8 and Figure 9 The diversion pipe 431 is provided with a rotating component 7, which is used to drive the telescopic pipe 432 to rotate. The rotating assembly 7 includes a rotating ring 71, a fixing frame 72, a connecting frame 73, and multiple driving plates 74. The inside of the diversion pipe 431 is provided with a rotating groove. The rotating ring 71 is rotatably disposed inside the rotating groove. The multiple driving plates 74 are fixedly connected in a ring to the inner side of the rotating ring 71. The fixing frame 72 is fixedly connected between the rotating rings 71. The connecting frame 73 is an inverted T-shaped frame, with its upper end fixedly connected to the middle of the rotating ring 71 and its lower end fixedly connected to the inside of the telescopic pipe 432. As the condensing system increases its operating power, the cooling water flow rate in the pipeline continues to increase. The total amount of water entering the diversion pipe 431 and the flow velocity increase linearly and synchronously. The impact intensity of the water flow in the variable diameter pipe gradually increases. The thrust of the high-speed water flow on the drive plate 74 continues to increase. The rotational resistance of the rotating component 7 is overcome, and the rotational speed continues to increase. The rotational speed of the telescopic pipe 432 and the nozzle 433 increases. As the rotational speed increases, the spray coverage radius of the nozzle 433 gradually expands. The spray range increases from small to large. The spray water flow evenly covers more condensing pipe areas. The water output from the spray nozzle of the diversion pipe 431 increases synchronously, and the impact force of the water flow dripping onto the diversion plate 6 continues to increase.

[0036] The rotational speed of the spray component 43 is entirely determined by the water flow velocity. Changes in water flow are reflected in the rotational motion. The two water outlet paths, spraying water from the nozzle 433 and dripping water from the spray port of the diversion pipe 431, work synchronously throughout the entire process. One path is responsible for water distribution and heat exchange in the condenser tube, and the other path is responsible for providing driving power to the air guide assembly 5. No matter how the inlet water flow changes, the variable diameter structure always accelerates the water flow a second time, ensuring that effective impact force and jet power can be formed under different loads.

[0037] Reference Figure 2 and Figure 4 Two exhaust fans 10 are provided above the condenser box 1. Two symmetrical side air guide spaces are formed between the two side plates 51 and the two sides of the inner wall of the condenser box 1. An upper air guide space is formed between the upper part of the sliding plate 52 and the top wall of the condenser box 1. The exhaust fans 10 are connected to the upper air guide space.

[0038] Two exhaust fans 10 are symmetrically installed on the top of the condenser box 1, and the air outlets are directly connected to the upper air guide space inside the box, providing negative pressure extraction power for the airflow inside the box.

[0039] After the equipment starts, the fan runs continuously, creating a stable negative pressure in the upper air guide space. The steam, after being guided by the air guide component 5, is attracted by the negative pressure, quickly passes through the upper air guide space, and is discharged from the housing by the fan. When the air guide channel is wide open, the steam flow rate increases, and the fan efficiently completes the large-flow exhaust; when the air guide channel is narrowed, the total air intake decreases, and the fan load decreases accordingly. The fan operates continuously throughout the entire process, and the exhaust status is matched in real time with the opening of the air guide channel and the spraying conditions.

[0040] It relies on negative pressure to quickly extract the steam generated by evaporation inside the chamber, avoiding steam accumulation that would cause the pressure inside the chamber to rise and the heat exchange efficiency to decrease. With the help of adjustable air guide channels, it reduces ineffective air extraction under low air volume conditions, thereby reducing equipment energy consumption.

[0041] This solved the problems of slow steam discharge, internal pressure buildup, and excessive energy consumption due to long-term full-load operation of the blower.

[0042] Reference Figure 3 A guide cover 11 is fixedly connected to the side of the second air vent 9 away from the first air vent 8. The upper surface of the guide cover 11 is an arc-shaped surface, and the lower part is set as an opening communicating with the second air vent 9. The staggered structure of the first air inlet 8 and the second air inlet 9 straightens the airflow. After the steam flows out of the condensation zone, it passes through the first and second air inlets 9 in sequence, and the flow direction is gradually straightened, so that large-scale turbulence and local deflection will not form in the box.

[0043] The fine water mist generated by the spray moves downwards due to gravity, while the steam flows upwards. The two layers of staggered shielding structure form a physical barrier, significantly reducing the probability of liquid water mist entering the exhaust duct with the airflow. On the one hand, this reduces the loss of cooling water with the exhaust, improving water recycling efficiency; on the other hand, it prevents water mist from entering the fan and air duct, reducing the problems of condensation and water corrosion on the inner wall of the air duct.

[0044] When used in conjunction with the guide cover 11 to form a flow guiding system, the airflow direction remains stable during the adjustment of the air inlet, and there will be no airflow turbulence due to the opening and closing of the channel, which also reduces the operating noise of the equipment.

[0045] Reference Figure 3 Multiple sliders 12 are symmetrically fixedly connected to both sides of the sliding plate 52. A strip-shaped groove is symmetrically opened inside the side plate near the sliding plate 52, and the sliders 12 are slidably disposed inside the strip-shaped groove. The cooperation between the slider 12 and the strip groove can prevent the sliding plate 52 from being subjected to external forces from the impact of steam and water flow, thereby preventing the sliding plate 52 from shifting position. This ensures the parallel setting of the first air inlet 8 and the second air inlet 9, and ensures the stable adjustment of the air channel.

[0046] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
