Description

Technical Field

[0001] This utility model relates to the field of cooling tower technology, and in particular, to a large-span steel structure and a fog-eliminating cooling tower. Background Technology

[0002] A cooling tower is a device that dissipates industrial waste heat through evaporation via the contact between water and air. In operation, dry, cool air enters the tower from the bottom and flows upwards, then comes into contact with and exchanges heat with the downward-spraying water, carrying the heat from the water away through the top of the tower. The cooling tower contains components such as packing material, water collectors, and defogging modules, supported by a steel structure installed within the tower. This steel structure typically includes columns and beams. Traditionally, these columns and beams are constructed using square or round tubular structures. Due to the limited load-bearing capacity of these materials, the span between adjacent columns is usually small, generally not exceeding 2.4 meters. This dense column arrangement results in a complex structure, large material consumption, and a long construction period, increasing manufacturing costs. Furthermore, the excessive number of columns and beams can impede airflow within the tower, thus reducing its cooling efficiency.

[0003] Therefore, the inventors needed to improve the steel structure inside the cooling tower to increase the column span while also providing good support. Utility Model Content

[0004] The technical problem to be solved by this utility model is: in order to overcome the above-mentioned defects in the prior art, a large-span steel structure for defogging cooling towers is provided.

[0005] A fog-eliminating cooling tower with this large-span steel structure is also provided.

[0006] The technical solution adopted by this utility model to solve its technical problem is: a large-span steel structure for a fog-eliminating cooling tower, comprising columns, beams, and connectors, all of which are H-beams. The beams are connected to the columns via connectors, and one end of the connector is fixedly connected to the column. The connector includes interconnected connecting wing plates and connecting web plates. The beams include interconnected beam wing plates and beam web plates. The end of the beam is connected to the end of the connector away from the column. A wing plate connecting plate is connected between the connecting wing plates and the beam wing plates. A web plate connecting plate is provided between the connecting web plates and the beam web plates.

[0007] Furthermore, the wing plate connecting plate is connected to the connecting wing plate and the crossbeam wing plate by mutually cooperating first bolts and first nuts, and the web plate connecting plate is connected to the connecting web plate and the crossbeam web plate by mutually cooperating second bolts and second nuts.

[0008] Furthermore, the wing plate connecting plate includes an outer connecting plate and an inner connecting plate. The outer connecting plate is disposed on the side of the crossbeam wing plate away from the crossbeam web plate, and the inner connecting plate is disposed on the other side of the crossbeam wing plate opposite to the outer connecting plate. There are two inner connecting plates, and the two inner connecting plates are located on opposite sides of the crossbeam web plate.

[0009] Furthermore, there are two web connecting plates, which are arranged opposite to each other on opposite sides of the web of the beam.

[0010] Furthermore, the connector is welded and fixedly connected to the column.

[0011] Furthermore, the uprights are made of HW-type steel, and the crossbeams are made of HN-type steel.

[0012] A fog-eliminating cooling tower, the fog-eliminating cooling tower comprising the large-span steel structure described in any of the preceding claims.

[0013] Furthermore, the defogging cooling tower also includes a tower body and a water distribution pipe, packing material, and water collector installed inside the tower body. The large-span steel structure is installed inside the tower body, and the water distribution pipe, packing material, and water collector are all installed on the large-span steel structure. The packing material is located below the water distribution pipe, and the water collector is located above the water distribution pipe.

[0014] Furthermore, an air inlet louver and a heat exchanger are installed on the side wall of the tower body. The heat exchanger is located above the water collector, and the air inlet louver is located below the packing.

[0015] The beneficial effects of this utility model are as follows: The large-span steel structure or mist-eliminating cooling tower of this utility model uses H-beams for its columns, beams, and connectors. Compared to traditional square or round tube columns, H-beams have significant advantages in bending resistance, torsion resistance, seismic resistance, and overall stability. This allows for large-span installation of the columns, increasing the span between columns to 5 meters, reducing the number of columns and beams, significantly reducing steel consumption, and lowering costs. Furthermore, the reduction in beams reduces obstruction of rising airflow, optimizes airflow organization within the tower, reduces wind resistance, and improves heat exchange efficiency.

[0024] The present invention will now be described in detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of the present invention, and therefore only show the components relevant to the present invention.

[0025] Please see Figures 1-5 This utility model provides a large-span steel structure for a fog-eliminating cooling tower. The large-span steel structure includes columns 1, beams 2, and connectors 3. There are multiple columns 1 arranged longitudinally, and beams 2 are arranged horizontally and fixedly connected between every two adjacent columns 1. The ends of beams 2 are fixedly connected to columns 1 through connectors 3. Columns 1, beams 2, and connectors 3 are all H-beams. The length of connectors 3 is much shorter than the length of columns 1 and beams 2. One end of connectors 3 is welded to column 1, and the other end of connectors 3 is bolted to beams 2. Thus, in actual assembly, the user can transport columns 1, beams 2, and connectors 3 to the destination before assembling. Specifically, connectors 3 are first welded to columns 1, and then beams 2 are installed and fixed to connectors 3 with bolts.

[0026] This invention, through the aforementioned design, allows for easy removal of the crossbeam 2 from the column 1 during subsequent maintenance and dismantling. Furthermore, since the column 1, crossbeam 2, and connector 3 are all made of H-beams, compared to traditional square or round tube columns, H-beams offer significant advantages in bending resistance, torsion resistance, seismic resistance, and overall stability. This enables large-span installation of the column 1, increasing the span between columns 1 to 5 meters, reducing the number of columns 1 and crossbeams 2, significantly reducing steel consumption, and lowering costs. Moreover, the reduction in the number of crossbeams 2 reduces obstruction of rising airflow, optimizes airflow organization within the tower, reduces wind resistance, and improves heat exchange efficiency.

[0027] The connector 3 includes two oppositely arranged connecting flanges 31 and a connecting web 32 fixedly connected between the two connecting flanges 31. The connecting web 32 is perpendicular to the connecting web 31. The crossbeam 2 includes two oppositely arranged crossbeam flanges 21 and a crossbeam web 22 fixedly connected between the two crossbeam flanges 21. The end of the crossbeam 2 is connected to the end of the connector 3 away from the column 1 and fits against each other. When the two are connected, the connecting flanges 31 and the crossbeam flanges 21 cooperate with each other, and the connecting web 32 and the crossbeam web 22 cooperate with each other. The shape and size of the end of the connector 3 are the same as the shape and size of the end of the crossbeam 2. Therefore, at this time, the connecting flanges 31 and the crossbeam flanges 21 are coplanar, and the connecting web 32 and the crossbeam web 22 are coplanar.

[0028] In this embodiment, a wing plate connecting plate 4 is provided between the connecting wing plate 31 and the crossbeam wing plate 21. Part of the wing plate connecting plate 4 is fixedly connected to the connecting wing plate 31, and part of the wing plate connecting plate 4 is fixedly connected to the crossbeam wing plate 21. A web plate connecting plate 5 is provided between the connecting web plate 32 and the crossbeam web plate 22. Part of the web plate connecting plate 5 is fixedly connected to the connecting web plate 32, and part of the web plate connecting plate 5 is fixedly connected to the crossbeam web plate 22. During installation, after the crossbeam 2 and the connecting member 3 are aligned, the wing plate connecting plate 4 is fixedly connected between the connecting wing plate 31 and the crossbeam wing plate 21, and the web plate connecting plate 5 is fixedly connected between the connecting web plate 32 and the crossbeam web plate 22. This achieves the connection of the wing plate and the web plate between the connecting member 3 and the crossbeam 2, improving the connection stability between the connecting member 3 and the crossbeam 2.

[0029] In this embodiment, the wing plate connecting plate 4 is connected to the connecting wing plate 31 and the crossbeam wing plate 21 by mutually cooperating first bolts 61 and first nuts 62, and the web plate connecting plate 5 is connected to the connecting web plate 32 and the crossbeam web plate 22 by mutually cooperating second bolts 71 and second nuts 72. During installation, the tail of the first bolt 61 passes through the wing plate connecting plate 4 and the corresponding wing plate, and is then locked and fixed by the first nut 62. Similarly, the tail of the second bolt 71 passes through the web plate connecting plate 5 and the corresponding web plate, and is then locked and fixed by the second nut 72.

[0030] In this embodiment, the wing plate connecting plate 4 includes an outer connecting plate 41 and an inner connecting plate 42. The outer connecting plate 41 is disposed on the side of the crossbeam wing plate 21 away from the crossbeam web plate 22, and the inner connecting plate 42 is disposed on the other side of the crossbeam wing plate 21 opposite to the outer connecting plate 41. There are two inner connecting plates 42, and the two inner connecting plates 42 are located on opposite sides of the crossbeam web plate 22.

[0031] In addition, there are two web connecting plates 5, which are arranged opposite to each other on the two sides of the crossbeam web 22 to improve the connection reliability between the connecting web 31 and the crossbeam web 22.

[0032] The column 1 includes two opposing column wing plates 11 and a column web plate 12 fixedly connected between the two column wing plates 11. The column wing plates 11 and the column web plate 12 are perpendicular to each other. During installation, the number of crossbeams 2 connected at the same height on the column 1 varies depending on the position of the column 1. For example, taking the top view of the large-span steel structure of this utility model as an example, from the top view perspective, supported by the column, a large rectangular structure is presented. This large rectangular structure is composed of multiple small rectangles formed by the intersecting crossbeams 2. At this time, two crossbeams 2 are connected to the columns 1 located at the four corners of the large rectangular structure, three crossbeams 2 are connected to the columns 1 located at the four edges, and four crossbeams 2 are connected to the columns 1 located at other positions. Taking the case where there are two crossbeams 2 connected to the column 1 as an example, one of the connectors 3 is fixedly connected to the column wing plate 11 by welding, and the other connector 3 is fixedly connected to the groove wall of the groove formed by the column wing plate 11 and the column web plate 12 by welding.

[0033] In one specific implementation, column 1 is HW-shaped steel and beam 2 is HN-shaped steel.

[0034] Please see Figure 6 This utility model also provides a defogging cooling tower, including the aforementioned large-span steel structure, a tower body 10, and a water distribution pipe 20, packing 30, and a water collector 40 all disposed within the tower body 10. The large-span steel structure is installed inside the tower body 10, and the water distribution pipe 20, packing 30, and water collector 40 are all installed on the large-span steel structure. The packing 30 is located below the water distribution pipe 20, and the water collector 40 is located above the water distribution pipe 20. The water distribution pipe 20 is placed horizontally inside the tower body 10 and is used to introduce circulating water into the tower. Under the action of the nozzle, the water is sprayed onto the packing 30. As the rising dry and cold air passes through the packing 30, it exchanges heat with the circulating water, thereby achieving cooling. Some of the water vapor in the humid and hot air passing through the packing 30 is intercepted when passing through the water collector 40, thereby achieving water saving and defogging functions. Finally, the airflow passing through the water collector flows out of the tower through the air outlet under the action of the fan installed at the top of the tower body 10.

[0035] In addition, an air inlet louver 50 and a heat exchanger 60 are installed on the side wall of the tower body 10. The heat exchanger 60 is located above the air inlet louver 50 and, more specifically, above the water collector 40. The air inlet louver 50 is located below the packing 30. Specifically, openings are provided on the side wall of the tower body 10, and the air inlet louver 50 and heat exchanger 60 are installed at corresponding openings. The air inlet louver 50 allows dry, cold air from outside the tower to enter the space below the packing 30. When the air enters the space above the water collector 40 through the upper opening, it flows through the heat exchanger 60. The heat exchanger 60 further reduces the temperature of the air entering the tower, further lowering the temperature of the humid, hot air passing upwards through the water collector 40, thereby condensing more water and improving water-saving efficiency. The heat exchanger 60 can be a coil heat exchanger, with a circulating cooling medium inside.

[0036] This utility model's large-span steel structure utilizes H-beams, which offer significant advantages in bending, torsion, seismic resistance, and overall stability. It enables large-span installation of the columns 1, reducing the number of columns 1 and beams 2, thus drastically reducing steel consumption and costs. Furthermore, the reduction in beams 2 minimizes obstruction of rising airflow, optimizes airflow organization within the tower, reduces wind resistance, and improves heat exchange efficiency.

[0037] The fog-eliminating cooling tower of this utility model has all the technical features of the aforementioned large-span steel structure, and therefore has the same technical effect as the aforementioned large-span steel structure.

[0038] Based on the above-described preferred embodiments of this utility model, and through the foregoing description, those skilled in the art can make various changes and modifications without departing from the scope of this utility model. The technical scope of this utility model is not limited to the contents of the specification, but must be determined according to the scope of the claims.
