[0002]目前,在水处理冷却领域中使用的淋水填料可分为折波填料、网格点滴填料、网格规整半软性填料等,其各有优缺点:折波填料通过水膜与空气接触吸收,填料比表面积大,传质时间长,布水、布气性能好,换热效率高,降温性能好,但在悬浮物高的污水工艺环境下填料承载能力差,容易堵塞、垮塌,影响正常生产;网格点滴填料以水滴形式与空气接触,填料阻力小、抗堵能力强、使用周期长,但比表面积较小,传质时间短,降温效果差;网格规整半软性填料通过液滴和水膜混合吸收,填料阻力小,抗堵能力强,布水、布气性能好,传质、换热效率高,但正方形网格内两片矩形叶片只有两处与网格连接,叶片悬空面积较大,在水力冲击下叶片间容易出现较大空隙,影响布水效果,同样也会影响传质及降温效果,由此,有必要对其进行改进
该类雪花多分支立体淋水降温填料采用一次性注塑成型制造,工作过程中,循环水从填料上方落下与上行空气对流实现传质降温,循环水通过填料单元的枝杆和叶片进行分散,其中,一部分液体经叶片间歇落入填料下方,另一部分经枝杆和叶片再次阻挡分散落入填料下方;由于主枝杆、副枝杆和小枝杆有一定的弹性,水中的悬浮物不易沉积在填料上。枝杆和叶片排列整齐,固定牢固,稳定性能好,既保证了填料助力小,抗堵能力强,布水、布气性能好,传质、降温效率高,又解决了填料叶片悬空面积大,在水力冲击下叶片间容易出现较大空隙,影响传质效果的问题,保持了填料的长周期高效运行。

Abstract
Description
Technical Field
[0001] This utility model relates to a cooling packing material, specifically a snowflake-like multi-branched three-dimensional water-spraying cooling packing material. Background Technology
[0002] Currently, water-spraying packings used in water treatment cooling can be categorized into corrugated packings, grid-drip packings, and grid-structured semi-soft packings, each with its own advantages and disadvantages. Corrugated packings absorb water through contact with air via a water film, resulting in a large specific surface area, long mass transfer time, good water and air distribution performance, high heat exchange efficiency, and good cooling performance. However, in wastewater processes with high suspended solids, the packing has poor load-bearing capacity and is prone to clogging and collapse, affecting normal production. Grid-drip packings contact air in the form of water droplets, resulting in low resistance, strong anti-clogging ability, and long service life. However, they have a small specific surface area, short mass transfer time, and poor cooling effect. Grid-structured semi-soft packings absorb water through a mixture of droplets and water film, resulting in low resistance, strong anti-clogging ability, good water and air distribution performance, and high mass and heat exchange efficiency. However, within a square grid, the two rectangular blades only connect to the grid at two points, resulting in a large suspended area. Under hydraulic impact, large gaps can easily appear between the blades, affecting water distribution and mass transfer and cooling effects. Therefore, it is necessary to improve these packings. Summary of the Invention
[0003] The purpose of this invention is to provide a snowflake-like multi-branched three-dimensional water-spraying cooling packing that achieves mass transfer by mixing water film and water droplets through contact with air via water spraying in a cooling tower; and features strong anti-clogging ability, good water and air distribution performance, and high mass transfer and heat exchange efficiency.
[0004] The technical solution of this utility model is: A snowflake-like multi-branched three-dimensional water-spraying cooling packing includes a frame and multiple packing units arranged regularly within the frame; characterized in that: each packing unit is composed of a surrounding plate, main branches, secondary branches, and small branches; the surrounding plate is hexagonal, and multiple main branches are evenly distributed in a bundle-like pattern on the inner surface of the surrounding plate; secondary branches are symmetrically arranged on the surrounding plate between the main branches; small branches are arranged on the surrounding plate between the main branches and secondary branches; blades are respectively arranged on both sides of the main branches, secondary branches, and small branches.
[0005] The distance between the edges of the enclosure is 100-150mm.
[0006] The blades described are needle-like.
[0007] The main branches, secondary branches, and sub-branches are all flat conical bodies with a thickness of 1.5–2.5 mm.
[0008] The ends of the main branches and secondary branches are connected to each other by small reinforcing bars to prevent deformation.
[0009] The ends of the main branches, secondary branches, and saplings are connected to each other by large reinforcing bars to improve overall strength.
[0010] The beneficial effects of this utility model are as follows: This type of snowflake-shaped multi-branched three-dimensional water-spraying cooling packing is manufactured using a one-time injection molding process. During operation, circulating water falls from above the packing and convects with the rising air to achieve mass transfer and cooling. The circulating water is dispersed through the branches and blades of the packing unit. Part of the liquid intermittently falls below the packing via the blades, while another part is further dispersed below the packing by the branches and blades. Due to the elasticity of the main branches, secondary branches, and small branches, suspended solids in the water are less likely to settle on the packing. The branches and blades are neatly arranged, firmly fixed, and have good stability. This ensures that the packing requires minimal effort, has strong anti-clogging ability, good water and air distribution performance, and high mass transfer and cooling efficiency. It also solves the problem of large gaps between the blades due to the large suspended area of the packing blades under water impact, which affects the mass transfer effect, thus maintaining the long-term high-efficiency operation of the packing.

[0012] This type of snowflake-shaped multi-branched three-dimensional water-spraying cooling packing includes a rectangular frame 1 and multiple packing units 2 arranged regularly within the frame 1. Each packing unit 2 consists of a surrounding plate 3, main branches 4, secondary branches 5, and small branches 6. The surrounding plate 3 is hexagonal, with a height of 40-50 mm and a side-to-side distance of 100-150 mm. Multiple main branches 4 are evenly distributed in a bundle-like pattern on the inner surface of the surrounding plate 3. Secondary branches 5 are symmetrically arranged on the surrounding plate 3 between the main branches 4, and small branches 6 are arranged on the surrounding plate 3 between the main branches 4 and secondary branches 5. One end of each main branch 4, secondary branch 5, and small branch 6 is fixedly connected to the inner wall of the surrounding plate 3, and the lengths of the main branches 4, secondary branches 5, and small branches 6 decrease sequentially. Each main branch 4, secondary branch 5, and small branch 6 is a flat conical shape with a thickness of 1.5-2.5 mm. The main branch 4, the secondary branch 5, and the small branch 6 are each provided with needle-like leaves 7 on both sides.
[0013] The ends of the main branch 4 and the secondary branch 5 are connected to each other by small reinforcing bars 8 to prevent deformation.
[0014] The ends of the main branch 4, secondary branch 5, and sapling 6 are connected by large reinforcing bars 9 to improve overall strength.
[0015] The packing material is manufactured using a one-time injection molding process. During operation, circulating water falls from above the packing material and convects with the upward air to achieve mass transfer and cooling. The circulating water is dispersed through the branches and blades 7 of the packing unit 2. Part of the liquid falls into the bottom of the packing material through the intermittent gaps between the branches and blades 7, while the other part is dispersed into the bottom of the packing material again by the obstruction of the branches and blades. Since the main branches 4, secondary branches 5, and small branches 6 have a certain degree of elasticity, the mass transfer and cooling process generates slight vibrations under the impact of the droplets, which makes it difficult for suspended solids in the water to settle on the packing material (branches and blades).
[0016] This packing material features improved overall strength and good stability. The ends of the main branches 4 and secondary branches 5 are connected by small reinforcing bars 8, while the ends of the main branches 4, secondary branches 5, and small branches 6 are connected by large reinforcing bars 9. This ensures both the packing material's ability to assist and resist clogging, and solves the problem of large gaps between blades in existing packing materials due to large suspended areas, which can affect mass transfer efficiency under hydraulic impact. Therefore, it maintains the packing material's long-term, high-efficiency operation, which is of positive significance to the company's development.
