The water collecting plate is composed of a corrugated folded plate and inclined fins, and the vibration drive component is used to achieve the effect of shaking off condensed water droplets by the reciprocating vibration of the corrugated folded plate.

Description

Technical Field

[0001] The invention relates to the technical field of cooling tower water collectors, in particular to a water retaining structure of a cooling tower. Background Art

[0002] A cooling tower is a device that uses the heat exchange between water and air flow to generate steam. The steam evaporates and takes away the heat, thereby achieving the goal of using the principles of evaporative heat dissipation, convection heat transfer, and radiation heat transfer to dissipate the waste heat generated in industrial equipment or refrigeration and air conditioning to reduce the water temperature and ensure the normal operation of the system.

[0003] The moisture carried in the hot and humid air discharged from the cooling tower, one part is water vapor mixed in the air, which cannot be separated from the air by mechanical methods, and the other part is tiny water droplets carried out with the airflow, which can usually be captured by a water collector; the water collector is generally composed of one or two rows of inclined slats or arc-shaped blade slats, and there are also those with a three-layer slat structure, so it is also called a water retaining plate or a water retaining structure, which is usually arranged above the nozzle of the water distribution pipe. In the rising process of water vapor, the water retaining structure provides a surface that can be impacted by the rising airflow, causing the water vapor to separate by inertia. The water droplets after the impact grow from small to large, fall back to the packing layer along the water retaining structure, and then flow back to the cooling tower.

[0004] In the process of recovering water vapor by the water retaining structure, the heat exchange between the ambient cold air and the water vapor out of the tower causes the water vapor to condense on the water retaining plate. Experiments have shown that the amount of heat exchange is the key factor affecting the condensation effect. Therefore, the condensation effect can be improved by increasing the heat exchange amount as much as possible.

[0005] When water vapor encounters a water retaining structure, it changes from gas phase to liquid phase. A large amount of heat is the latent heat of vaporization brought out through the cold air side. After the water vapor exchanges heat with the cold side, the water vapor becomes condensed liquid. If the condensed liquid is not quickly stripped and collected, it will form a water film on the surface of the water retaining structure, thereby reducing the heat exchange rate. Therefore, quickly collecting condensed liquid droplets is the key to improving heat exchange efficiency and water vapor collection efficiency. Based on this, a water retaining structure for a cooling tower is provided. Summary of the invention

For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances. The following is an explanation of an embodiment of the present invention based on the overall structure of the present invention.

[0028] See also Figures 1 to 7In an embodiment of the present invention, a water retaining structure of a cooling tower includes a water collecting plate 1 and an assembly component 2. The water collecting plate 1 and the assembly component 2 are horizontally arranged in multiple numbers and staggered with each other. The water collecting plate 1 is composed of a corrugated folded plate 101 and an inclined fin 102. The assembly component 2 is used to form a channel for water vapor to pass through between two corrugated folded plates 101. The vertical section of the corrugated folded plate 101 is a sideways "Ω"-shaped structure, and the top-view cross-section of the corrugated folded plate 101 is a corrugated structure. The inclined fins 102 are symmetrically formed on both sides of the outer wall of the corrugated folded plate 101, and are used to increase the contact area between the corrugated folded plate 101 and water vapor under the conditions of the same height and width.

[0029] The assembly component 2 includes a side panel 201 and a connecting sleeve 202 . The connecting sleeve 202 is symmetrically fixed to the upper and lower ends of the side panel 201 . Two groups of side panels 201 are symmetrically arranged between two adjacent corrugated folded plates 101 . The two groups of side panels 201 are used to provide spacing support for the two corrugated folded plates 101 .

[0030] A vibration drive assembly 6 is also provided between the two sets of side panels 201. The vibration drive assembly 6 converts the impact force of the rising airflow into rotational force and squeezes and pushes a corrugated folding plate 101, thereby achieving the effect of reciprocating vibration of the corrugated folding plate 101 to shake off the condensed water droplets.

[0031] The vibration drive component 6 includes a rotating shaft 601, a fan blade 602, and an arc-shaped pressure rod 603; the rotating shaft 601 is limitedly rotated and connected between the two side plates 201, the fan blade 602 is fixed on the outside of the rotating shaft 601, and the arc-shaped pressure rod 603 is fixed on one side of the outer wall of the rotating shaft 601; the rising airflow through the middle channel of the two corrugated folded plates 101 pushes the fan blade 602, so as to realize the overall rotation of the rotating shaft 601, the fan blade 602, and the arc-shaped pressure rod 603, and the fan blade 602 rotates and contacts a corrugated folded plate 101 to realize the squeezing and pushing of the corrugated folded plate 101; the contact position of the arc-shaped pressure rod 603 and the corrugated folded plate 101 is the bending part of the corrugated folded plate 101 in the vertical direction, and the corrugated folded plate 101 is formed with a reinforcing convex rib 104 at this bending part; the vibration drive component 6 and the reinforcing convex rib 104 are arranged in two groups along the vertical direction.

[0032] A plurality of water collecting plate components 1 and an assembly component 2 are assembled by means of a side convex connecting rod 3 and a nut 4; a stopper is provided at one end of the side convex connecting rod 3, and the other end passes through a plurality of corrugated folded plates 101 and a connecting sleeve 202 in sequence; the nut 4 is threadedly connected to the other end of the side convex connecting rod 3 and fits with the end face of the connecting sleeve 202 at the rear end; a through hole is provided on the corrugated folded plate 101 for the side convex connecting rod 3 to pass through, and the inner diameters of the through hole and the connecting sleeve 202 match the outer diameter of the side convex connecting rod 3.

[0033] Fixed columns 103 are symmetrically fixed at both ends of the outer wall of the corrugated folded plate 101. The number and position of the fixed columns 103 correspond to the through holes and are concentrically distributed. A telescopic spring 5 is arranged on the inner side of the fixed column 103. The telescopic spring 5 is sleeved on the outer side of the side convex connecting rod 3 and the two ends of the telescopic spring 5 are respectively fitted with the inner wall of the fixed column 103 and the end face of the connecting sleeve 202.

[0034] In the present embodiment: It should be additionally explained that: the front end of the side convex connecting rod 3 is formed with a circular stopper whose outer diameter is larger than the outer diameter of the telescopic spring 5, and the corrugated folded plate 101 distributed at the front end forms a gap with the stopper through the telescopic spring 5, and the outer side of the rear end of the side convex connecting rod 3 is formed with an external thread for the threaded connection of the nut 4, the nut 4 is spirally connected to the external thread and fits with the end face of the connecting sleeve 202 distributed at the rear end.

[0035] The water collector composed of multiple water collecting plates 1 and assembly components 2 is installed and placed inside the cooling tower (it should be noted that the installation of the water retaining structure can be assisted by the bracket, and the conventional connection structure in the prior art can be used, for example, the two ends of the opposite convex connecting rod 3 are fixed by a clamp, so the installation structure of the water retaining structure is not elaborated here). When the cooling tower is running, the generated humid hot air will rise along the channel between the two adjacent corrugated folded plates 101; in this process, the humid hot air collides with the surface of the corrugated folded plate 101, causing the water vapor to be inertially separated, and the water vapor condenses on the surface of the corrugated folded plate 101 to form water droplets. It should be noted that the vertical bending structure of the corrugated folded plate 101 and the horizontal corrugated structure can increase the contact area between the humid hot air and the corrugated folded plate 101, and the inclined fins 102 can further expand the contact area between the water retaining structure and the humid hot air, thereby achieving the effect of improving the water vapor separation efficiency.

[0036] At the same time, the rising airflow can form a thrust on the fan blades 602, so that the fan blades 602 drive the rotating shaft 601 to rotate, and the rotating rotating shaft 601 drives the arc pressure rod 603 to rotate. In this process, when the arc pressure rod 603 rotates to contact the reinforcing protruding ribs 104 distributed on the front end corrugated folded plate 101, it will form knocking vibration and extrusion on the reinforcing protruding ribs 104. Under the action of this extrusion force, the front end corrugated folded plate 101 moves toward the front end direction and squeezes the telescopic spring 5 at the front end to contract, so that the arc pressure rod 603 can continue to rotate and move away from the reinforcing protruding ribs 104. At this time, the corrugated folded plate 101 loses the extrusion force and will be moved under the reset elastic force of the telescopic spring 5 at the front end. By using the downward reset movement (it should be noted that the reset corrugated folding plate 101 will be blocked by the rear end telescopic spring 5, and the rear end telescopic spring 5 has a buffering and intercepting effect to prevent the reset corrugated folding plate 101 from being too close to the fan blade 602 and causing collision damage), the reciprocating vibration of the corrugated folding plate 101 can be achieved through the continuous rotation of the arc pressure rod 603. This vibration force will cause the water droplets on the surface of the corrugated folding plate 101 to be shaken off and drip or flow downward, thereby increasing the speed and efficiency of the water droplets gathering downward, avoiding the formation of water film on the surface of the corrugated folding plate 101, and effectively preventing the occurrence of water film thermal resistance effect, thereby improving the heat exchange efficiency, and further achieving the effect of further improving the water vapor collection efficiency.

[0037] Please refer to Figures 1 to 4 A screw hole 203 is provided on the outer side of the connecting sleeve 202 , and a fastening screw 204 is threadedly connected to the inner side of the screw hole 203 . The fastening screw 204 is tightly fitted with the outer side of the lateral convex connecting rod 3 .

[0038] In this embodiment: by fastening the screw 204, which is threadedly connected to the screw hole 203 and tightly fits with the outer side of the side convex connecting rod 3, the connection and fixation between the connecting sleeve 202 and the side convex connecting rod 3 are achieved, thereby providing a stable support for the operation of the vibration drive assembly 6, so that the rotational extrusion force of the arc pressure rod 603 can be stably transmitted to the corrugated folding plate 101.

[0039] Please refer to Figures 1 to 7 The horizontal width of the side plate 201 is smaller than the distribution spacing of the two corrugated folded plates 101, the distance from the end face of the bent portion of the corrugated folded plate 101 distributed at the rear end of the connecting sleeve 202 to the rotating shaft 601 is larger than the outer diameter of the rotation track of the arc pressure rod 603, and the distance from the end face of the bent portion of the corrugated folded plate 101 distributed at the front end of the side plate 201 to the rotating shaft 601 is smaller than the outer diameter of the rotation track of the arc pressure rod 603.

[0040] In this embodiment: this structure can prevent the side plate 201 from interfering with the reciprocating vibration of the two corrugated folded plates 101 at the front and rear ends; at the same time, when the arc pressure rod 603 rotates, it will only squeeze the corrugated folded plate 101 at the front end and will not contact the corrugated folded plate 101 at the rear end, thus ensuring the independent vibration of multiple corrugated folded plates 101 and making the operation stable.

[0041] Please refer to Figures 1 to 7 There are multiple fan blades 602 arranged along the long side direction of the rotating shaft 601, and the multiple fan blades 602 are respectively distributed on both sides and the middle of the rotating shaft 601; two arc-shaped pressure rods 603 are symmetrically arranged on the outer side of the rotating shaft 601, and the movement trajectories of the two arc-shaped pressure rods 603 match the distribution positions of the reinforcing raised ribs 104.

[0042] In this embodiment: through the arrangement of multiple fan blades 602, the force on the rotating shaft 601 is made more uniform. At the same time, through the arrangement of multiple fan blades 602, the deflection force on the rotating shaft 601 can be large enough, thereby providing sufficient extrusion force for the corrugated folding plate 101; the movement trajectory of the two arc-shaped pressure rods 603 matches the distribution position of the reinforcing protruding ribs 104, so that the arc-shaped pressure rods 603 can ensure stable contact with the reinforcing protruding ribs 104 when rotating, and make the corrugated folding plate 101 produce regular and balanced vibration.

[0043] Please refer to Figures 1 to 3 The distance between the end face of the fixed cylinder 103 and the end face of the connecting sleeve 202 is greater than the distance of the reciprocating vibration of the corrugated folded plate 101.

[0044] In this embodiment: this structure can prevent the fixed column 103 from having a hard collision with the end surface of the connecting sleeve 202 when the corrugated folded plate 101 vibrates back and forth.

[0045] What is described above is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
