Abstract
Description
Technical Field
[0001] This utility model relates to the field of water baffle blade technology, specifically a multi-stage low water flow rate water baffle blade. Background Technology
[0002] Water baffles are core vapor-water separation components in equipment such as central air conditioning, industrial cooling towers, and ventilation and air conditioning systems. Their main function is to intercept water vapor carried by the airflow, preventing it from being carried out of the equipment. Currently, most water baffle blades on the market use flat, straight splicing or simple bending structures, resulting in a short water-blocking path and insufficient residence time of the airflow within the baffle, leading to incomplete water vapor condensation. Furthermore, most water baffles lack a dedicated airflow guiding structure at the front end, making it easy for turbulence to be generated after the airflow enters the baffle. This turbulence can carry away uncondensed water vapor, further reducing the water-blocking effect. In addition, traditional water baffles lack components to separate the water film on their surface. After water vapor forms a continuous water film on the baffle surface, it is easily carried away by the airflow impact, resulting in poor water-blocking effect and high water flow rate, which is difficult to meet the low water flow rate requirements of high-precision air handling equipment.
[0003] Therefore, a multi-stage low-flow-rate baffle blade is proposed to solve the problems mentioned above. Utility Model Content
[0004] To address the shortcomings of existing technologies, this invention provides a multi-stage low-water-flow-rate baffle blade. The blade consists of four baffles connected sequentially by an arc to form a central concave structure, extending the airflow path and residence time within the baffles. Combined with a parallel plate extending in the airflow direction on the first baffle, it pre-guides the airflow smoothly into the main area, avoiding the turbulence and uncondensed water vapor escape defects of traditional baffles due to the lack of a guiding structure. Furthermore, six blades bent in the airflow direction at different locations form a multi-layered blocking structure, increasing the contact area between the airflow and the baffle structure, thus solving the problems mentioned in the background art.
[0005] To achieve the above objectives, the present invention provides the following technical solution: including a first water baffle, a second water baffle, a third water baffle, and a fourth water baffle, wherein the first water baffle, the second water baffle, the third water baffle, and the fourth water baffle are sequentially fixedly connected by an arc structure to form four continuous water baffle structures; The bending directions of the second and third water baffles are opposite to those of the first and second water baffles. The bending directions of the first and second water baffles are the same as those of the third and fourth water baffles, so that the middle of the water baffles forms a concave effect. A parallel plate is fixedly connected to the side of the first water baffle away from the second water baffle, and the parallel plate extends horizontally in the direction of airflow.
[0006] Preferably, the fourth baffle plate is provided with a second connecting hole on the side near the third baffle plate, and a sixth blade is fixedly connected to the second connecting hole on the side near the third baffle plate.
[0007] Preferably, the fourth baffle plate is provided with a tail hook on the side away from the third baffle plate, and the tail hook is bent toward the third baffle plate.
[0008] Preferably, a blade is fixedly connected to the outer arc of the first baffle plate and the second baffle plate, a blade is fixedly connected to the outer arc of the second baffle plate and the third baffle plate, a blade is fixedly connected to the outer arc of the third baffle plate and the fourth baffle plate, a blade is provided on the side of the second baffle plate near the first baffle plate, and a blade is provided on the side of the third baffle plate near the second baffle plate.
[0009] Preferably, blades 1, 2, 3, 4, 5, and 6 are all bent in the direction of airflow.
[0010] Preferably, the surfaces of the second and third baffles are provided with spikes, and the three spikes are respectively located at the middle position between the second and third blades, the middle position between the fourth and fifth blades, and the middle position of the side of the third baffle away from the fourth blade.
[0011] Compared with the prior art, this utility model provides a multi-stage low water flow rate baffle blade, which has the following beneficial effects: 1. The concave structure in the middle, formed by four water baffles connected by arcs, extends the flow path and residence time of the airflow within the water baffles. Combined with the parallel plate extending in the direction of airflow on the first water baffle, the airflow is pre-guided to smoothly enter the main area, avoiding the defects of traditional water baffles that generate turbulence and carry away uncondensed water vapor due to the lack of a guiding structure. Furthermore, the six blades bent in the direction of airflow at different positions form a multi-layered blocking structure, increasing the contact area between the airflow and the water baffle structure, further enhancing the vapor-water separation effect, and thus improving the basic efficiency of vapor-water separation.
[0012] 2. By setting spikes in the areas where water vapor tends to accumulate on the second and third baffles, the continuous water film formed on the surface of the baffles is divided into small pieces. This avoids the problem of water film being carried away by the airflow due to the lack of separating components in traditional baffles. At the same time, by setting a tail hook at the end of the fourth baffle that bends towards the third baffle, the residual water vapor in the airflow is finally intercepted, and the water droplets dripping from the surface of the baffles are collected and guided to the drainage system, further reducing the water flow rate and thus meeting the low water flow rate requirements of high-precision air handling equipment.

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model. Example
[0016] Please see Figure 1 - Figure 5This embodiment describes a multi-stage low-water-passage baffle blade, comprising a first baffle 1, a second baffle 2, a third baffle 3, and a fourth baffle 4. The first baffle 1, the second baffle 2, the third baffle 3, and the fourth baffle 4 are sequentially fixedly connected by an arc structure to form four continuous baffle structures. The arc structure allows the airflow to flow smoothly along the surface of the baffle, ensuring sufficient contact and condensation of water vapor with the baffle surface. To further extend the residence time of the airflow within the baffle, the four baffles are designed with specific bending directions. The bending directions of the second baffle 2 and the third baffle 3 are opposite to those of the first baffle 1 and the second baffle 2, while the bending directions of the first baffle 1 and the second baffle 2 are the same as those of the third baffle 3 and the fourth baffle 4. This creates a concave effect in the middle of the baffle, extending the airflow path and increasing the condensation time of water vapor within the baffle.
[0017] At the initial end where the airflow enters the baffle, in order to avoid the decrease in separation efficiency caused by the chaotic incoming airflow, a parallel plate 5 is fixedly connected to the side of the first baffle 1 away from the second baffle 2. The parallel plate 5 extends horizontally in the direction of airflow. The parallel plate 5 pre-regulates the chaotic incoming airflow into a stable airflow bundle and guides the airflow into the main area of the baffle, avoiding the problem of turbulence and rapid escape of uncondensed water vapor caused by the lack of a guiding structure in traditional baffles.
[0018] A first blade 9 is fixedly connected to the outer arc of the first baffle plate 1 and the second baffle plate 2. A third blade 10 is fixedly connected to the outer arc of the second baffle plate 2 and the third baffle plate 3. A fifth blade 11 is fixedly connected to the outer arc of the third baffle plate 3 and the fourth baffle plate 4. A second blade 12 is provided on the side of the second baffle plate 2 closest to the first baffle plate 1. A fourth blade 14 is provided on the side of the third baffle plate 3 closest to the second baffle plate 2. At the same time, a second connecting hole 6 is provided on the side of the fourth baffle plate 4 closest to the third baffle plate 3. 3. A sixth blade 7 is fixedly connected to one side, and the first blade 9, the second blade 12, the third blade 10, the fourth blade 14, the fifth blade 11 and the sixth blade 7 are all bent in the direction of airflow. The blades bent in the direction of airflow play a role in blocking and deflecting the airflow, while increasing the contact area between the airflow and the water-blocking structure, allowing more water vapor to condense on the blade surface, further extending the airflow path and improving the basic efficiency of vapor-water separation. The first water-blocking plate is connected to the first connecting hole, and the second connecting hole 6 and the first connecting hole are used to fix the water-blocking plate blades.
[0019] The second baffle plate 2 and the third baffle plate 3 are provided with spikes 15. The three spikes 15 are respectively located in the middle of the second blade 12 and the third blade 10, in the middle of the fourth blade 14 and the fifth blade 11, and in the middle of the side of the third baffle plate 3 away from the fourth blade 14. These three locations are areas where the airflow speed is relatively slow and water vapor is easy to gather to form a large area of continuous water film. The spikes 15 can divide these continuous water films into small independent water films, preventing the water film from being carried away by the airflow as a whole due to its large area and increased weight.
[0020] The fourth baffle plate 4 is provided with a tail hook 8 on the side away from the third baffle plate 3. The tail hook 8 bends toward the third baffle plate 3 to intercept the residual water vapor flowing through the end of the fourth baffle plate 4. It guides the water droplets to drip along the inner wall of the tail hook 8 into the equipment drainage system, avoiding the problem of residual water vapor and dripping water droplets flying out with the airflow due to the lack of end interception structure in traditional baffle plates, and further reducing the water flow rate.

As long as they can achieve their beneficial effects, they can be implemented. Therefore, this embodiment will not elaborate on their specific structural composition and working principle.
