When replacing the packing, only the packing block to be replaced needs to be moved.

Description

Technical Field

[0001] This utility model relates to the field of cooling towers, and more specifically, to a cooling tower structure. Background Technology

[0002] A cooling tower is a heat exchange device used to lower the temperature of water. It mainly discharges waste heat generated in industrial or air conditioning systems into the atmosphere through evaporative heat dissipation and convective heat transfer.

[0003] First, hot water from industrial equipment or a power plant enters the cooling tower through a delivery pipe. The cooling tower is equipped with spray heads located above the delivery pipe, which spray cooling water onto the pipe, thus cooling the hot water. The temperature of the hot water is transferred to the cooling water. A packing layer is located below the delivery pipe; after contacting the pipe, the cooling water enters the packing layer, which slows its descent. Simultaneously, a ventilation grille is located below the packing layer, and a fan is located at the top of the tower. When the fan is activated, it draws cold air from outside through the ventilation grille into the cooling tower. This cold air passes through the packing layer, carrying away the heat from the cooling water within and exiting the tower from the top. After passing through the packing layer, the cooling water is cooled by the cold air and finally falls into a collection tank within the tower. A spray pump is also installed in the cooling tower, which continues to pump the cooling water from the collection tank back to the spray heads. This cycle repeats, thus cooling the hot water in the delivery pipe.

[0004] In the above process, the cooling rate of the delivery pipe is closely related to the temperature of the cooling water. When the weather is hot, the temperature difference between the cooling water and the air temperature decreases, which leads to a decrease in the heat exchange efficiency of the packing. The temperature of the cooling water after passing through the packing layer is too high, which is not conducive to the subsequent cooling effect.

[0005] Therefore, a new solution is needed to address this problem. Utility Model Content

[0006] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a cooling tower structure.

[0007] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a cooling tower structure, including a tower body, wherein a main packing layer and an auxiliary packing layer are provided in the tower body, the auxiliary packing layer is located below the main packing layer, a water collection trough is provided at the bottom of the tower body, ventilation grilles are provided on two opposite side walls of the tower body, the ventilation grilles are located between the water collection trough and the main packing layer, the auxiliary packing layer is composed of a plurality of packing blocks, the plurality of packing blocks are arranged along the length direction of the auxiliary packing layer, and a plurality of lifting rods are provided in the tower body corresponding one-to-one with the packing blocks, the lifting rods being able to drive the packing blocks to move into the water collection trough individually.

[0008] The present invention is further configured such that: the two ends of the packing block are respectively provided with through holes and threaded holes, the lifting rod is threadedly connected to the threaded holes, a lead screw passes through the through holes, the two ends of the lifting rod are respectively rotatably connected to the bottom of the water collection tank and the tower body, and a motor for driving the lifting rod to rotate is fixedly connected to the outer wall of the tower body.

[0009] The present invention is further configured such that: a first gear is fixedly connected to the lifting rod, and a second gear that meshes with the first gear is fixedly connected to the output shaft of the motor.

[0010] The present invention is further configured such that: the packing block includes an outer frame and a plurality of packing units, the outer frame is provided with a plurality of mounting grooves, and rigid strips are fixedly connected to both sides of the packing unit, and the packing unit is fixedly connected to the mounting groove by fixing bolts passing through the rigid strips.

[0011] The present invention is further configured such that: the thickness of the packing unit is less than the thickness of the outer frame; a plurality of load-bearing rods are provided in the mounting groove; the load-bearing rods are located on the side of the packing unit facing the main packing layer; and there is a distance between all the load-bearing rods and the packing unit.

[0012] The present invention is further configured such that: two mounting blocks are provided in the mounting groove, all the load-bearing rods are located between the two mounting blocks, and the fixing bolts located on the rigid strip also pass through the mounting blocks.

[0013] In summary, this utility model has the following beneficial effects:

[0014] By driving the lifting rod, the auxiliary packing layer moves upward and fits into the main packing layer. This design increases the thickness of the entire packing layer, allowing the cooling water to remain in the packing for a longer time. This gives the cooling water more time to come into contact with the air passing through the ventilation grille, thus ensuring the cooling effect of the cooling water. The auxiliary packing layer is divided into several individually controllable packing blocks. On the one hand, this facilitates the overall maintenance of the auxiliary packing layer. When replacing the packing, only the packing block to be replaced needs to be moved. On the other hand, when the temperature is low, the packing blocks located in the water collection tank can move up and down to enhance the fluidity of the liquid in the water collection tank, making the water collection tank less prone to freezing.

[0020] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0021] A cooling tower structure, such as Figure 1 and Figure 3 As shown, the system includes a tower body 1, with a ventilation fan at the top. Inside the tower body 1 are a main packing layer 2 and an auxiliary packing layer. A conveying pipe and spray nozzles are located above the main packing layer 2, and the auxiliary packing layer is located below the main packing layer 2. A water collection trough 3 is located at the bottom of the tower body 1. Ventilation grilles 4 are installed on two opposite side walls of the tower body 1, located between the water collection trough 3 and the main packing layer 2. The auxiliary packing layer consists of several packing blocks 5 arranged along the length of the auxiliary packing layer. Inside the tower body 1 are several lifting rods 6, each corresponding to a packing block 5. The lifting rods 6 can individually drive the packing blocks 5 to move into the water collection trough 3. This system is effective when the temperature is relatively low. At this time, the auxiliary packing layer descends below the ventilation grille and is located in the water collection tank 3. The water in the water collection tank 3 is pumped into the spray head by the water pump and sprayed out, thus spraying onto the delivery pipe, thereby reducing the temperature of the liquid inside the delivery pipe. After absorbing the temperature of the delivery pipe, the cooling water becomes hotter. Because the ambient temperature is relatively low, the heat exchange efficiency between the cooling water and the air is relatively high. When the cooling water enters the main packing layer 2, the falling speed of the cooling water is slowed down, and the ventilation fan can draw the external air from the ventilation grille and pass upward through the main packing layer 2 to cool the cooling water in the main packing layer 2, so that the cooling water remains at a low temperature when it falls into the water collection tank 3.

[0022] like Figure 1 , Figure 2 and Figure 3As shown, when the outside temperature is relatively high, the temperature difference between the cooling water and the outside temperature decreases after the cooling water is sprayed onto the delivery pipe, resulting in a relatively poor heat exchange effect. By driving the lifting rod 6, the auxiliary packing layer moves upward and fits into the main packing layer 2. This arrangement increases the thickness of the entire packing layer, allowing the cooling water to remain in the packing for a longer time. This gives the cooling water more time to come into contact with the air passing through the ventilation grille, thus ensuring the cooling effect of the cooling water. Furthermore, by improving the working efficiency of the ventilation fan, the air can pass through the thickened packing layer. The auxiliary packing layer is divided into several individually controllable packing blocks 5. On the one hand, this facilitates the overall maintenance of the auxiliary packing layer. When replacing the packing, only the packing block 5 that needs to be replaced needs to be moved. On the other hand, when the temperature is low, the packing blocks 5 located in the water collection tank 3 can move up and down to enhance the fluidity of the liquid in the water collection tank 3, making the water collection tank 3 less prone to freezing.

[0023] like Figure 1 and Figure 3 As shown, the packing block 5 has through holes 7 and threaded holes 8 at both ends. The lifting rod 6 is threaded into the threaded hole 8, and a lead screw 9 passes through the through hole 7. The two ends of the lifting rod 6 are rotatably connected to the bottom of the water collection tank 3 and the tower body 1, respectively. The two ends of the lead screw 9 are fixedly connected to the bottom of the water collection tank 3 and the tower body 1, respectively. A motor 10 that drives the lifting rod 6 to rotate is fixedly connected to the outer wall of the tower body 1. The number of motors 10 is equal to the number of lifting rods 6. The lifting rod 6 is driven to rotate by the motor 10, so that the packing block 5 can rise and fall along the lifting rod 6. The lead screw 9 is set to guide the movement of the packing block 5. A gear 1 is fixedly connected to the lifting rod 6. A gear 2 that meshes with the gear 1 is fixedly connected to the output shaft of the motor 10. A through groove is opened on the outer wall of the tower body 1. The gear 1 and gear 2 mesh in the through groove. A protective shell is also provided on the outer wall of the tower body 1. The protective shell covers all the through grooves. Through the meshing of the gear 1 and gear 2, the force of the motor 10 shaft rotation can be transmitted to the lifting rod 6.

[0024] like Figure 1 and Figure 4As shown, the packing block 5 includes an outer frame 11 and several packing units 12. The outer frame 11 has several mounting slots 13. Rigid strips 14 are fixedly connected to both sides of each packing unit 12, and the packing unit 12 is fixedly connected between two rigid strips 14. The packing unit 12 is fixedly connected to the mounting slot 13 by fixing bolts passing through the rigid strips 14. The outer frame 11 has several mounting holes, and internal threads are formed on the inner circumferential walls of the mounting holes. After the packing unit 12 is placed into the mounting slot 13, it is fixed using fixing bolts. The fixing bolts pass through the rigid strips 14 and are threaded into the mounting holes, thus fixing the packing unit 12. The bolted connection ensures the installation strength of the packing unit 12. The fixing bolts, outer frame 11, and rigid strips 14 are all made of stainless steel, and the thickness of the packing unit 12 is less than the thickness of the outer frame 11. The installation groove 13 is equipped with several load-bearing rods 15. The load-bearing rods 15 are located on the side of the packing unit 12 facing the main packing layer 2. There is a distance between all the load-bearing rods 15 and the packing unit 12. When people replace the packing unit 12 on the packing block 5, they lower the packing block 5 to the bottom of the water collection tank 3 so that the bottom of the water collection tank 3 supports the packing block 5. The load-bearing rods 15 can bear the weight of people so that people can walk on the packing block 5 and prevent the packing unit 12 from being trampled. There are two installation blocks 16 in the installation groove 13. All the load-bearing rods 15 are located between the two installation blocks 16. The fixing bolts on the rigid strip 14 also pass through the installation blocks 16. The installation blocks 16 and the rigid blocks are connected in the installation hole by the same fixing bolt. This arrangement allows the packing unit 12 and the load-bearing rods 15 to be disassembled at the same time by unscrewing the fixing bolt, which is convenient for people to operate.

All technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
