Description

Technical Field

[0001] The utility model relates to the technical field of cooling towers, and more specifically, to a long-life cooling tower. Background Art

[0002] Cooling towers are equipment used in industrial production or power generation facilities. Their main function is to reduce the heat generated in equipment or processes through water circulation and gas exchange.

[0003] First, hot water enters the cooling tower from industrial equipment or power plants through a delivery pipe. A spray head is provided in the cooling tower above the delivery pipe. The spray head sprays cooling water on the delivery pipe, thereby cooling the hot water in the delivery pipe. At this time, the temperature in the hot water is transferred to the cooling water. A filler is provided in the cooling tower below the delivery pipe. The cooling water enters the filler after contacting the delivery pipe. The filler can slow down the falling speed of the cooling water. At the same time, a ventilation grille is provided below the filler and a fan is provided at the top of the cooling tower. When the fan is started, the external cold air enters the cooling tower through the ventilation grille, and the cold air takes away the temperature of the cooling water in the filler through the filler and leaves the cooling tower from the top of the tower. After the cooling water passes through the filler, the cooling water has been cooled by the cold air, and the cooling water finally falls into the sump in the cooling tower. A spray pump is also provided in the cooling tower. The spray pump continues to transport the cooling water in the sump to the spray head, and the cycle is repeated, thereby cooling the hot water in the delivery pipe.

[0004] In the above process, since the pores of the ventilation grille are relatively large and the area around the cooling tower is an industrial area with more dust particles, the dust particles can easily pass through the ventilation grille into the sump. After a long period of operation, there are more dust particles in the sump and they can be easily transported to the sprinkler head through the sprinkler pump, thus affecting the life of the sprinkler head and sprinkler pump in the cooling tower.

[0005] Therefore, new solutions need to be proposed to solve this problem. Utility Model Content

[0006] In view of the deficiencies in the prior art, the utility model aims to provide a cooling tower with a long service life.

[0007] The above technical purpose of the utility model is achieved through the following technical solutions: a long-life cooling tower, including a tower body, a water collecting tank located in the tower body and a spray head, a spray pump is fixedly connected to the outside of the tower body, the spray pump includes an inlet end connected to the water collecting tank and an outlet end connected to the spray head, a filter screen is provided in the water collecting tank to wrap the inlet end, an adsorption plate for adsorbing particles is provided on one side wall of the water collecting tank, the inlet end is arranged close to the adsorption plate, a water adding port for adding water to the water collecting tank is arranged in the water collecting tank, the water adding port is close to the adsorption plate and the water adding port is aligned with the adsorption plate.

[0008] The utility model is further configured as follows: the filter screen is located on the path from the water filling port to the adsorption plate.

[0009] The utility model is further configured as follows: a fixing frame is fixedly connected to the outer edge of the filter screen, a threaded hole for passing a fixing bolt is opened on the fixing frame, and the fixing frame is fixed to the side wall of the inlet end of the water collecting tank by the fixing bolt.

[0010] The utility model is further configured as follows: a fixing frame with an L-shaped cross-section is fixedly connected to one side wall of the water collecting trough, the length direction of the fixing frame is arranged along the depth direction of the water collecting trough, and the distance from the side wall of the inlet end of the water collecting trough to the fixing frame is equal to the width of the adsorption plate.

[0011] The utility model is further configured as follows: the adsorption plate comprises an adsorption portion and a fixing portion arranged along the outer edge of the adsorption portion, one side of the adsorption portion is flush with the fixing portion, and the other side of the adsorption portion protrudes away from the fixing portion.

[0012] The utility model is further configured as follows: a handle is provided on one side of the fixing portion.

[0013] The utility model is further configured as follows: the adsorption part is made of activated carbon.

[0014] In summary, the utility model has the following beneficial effects: the filter can separate the particles in the cooling water, so that the particles cannot enter the spray pump, thereby ensuring the safety of the spray pump and the spray head, thereby ensuring the overall life of the spray head and the spray pump. In the process of absorbing cooling water at the inlet end, the solid particles in the cooling water are easy to gather near the inlet end. The adsorption plate is arranged close to the inlet end, so that the adsorption plate can adsorb the solid particles, thereby reducing the activity of the particles around the inlet end, reducing the filtration pressure of the filter, and making the filter less likely to be blocked by the particles. The water filling port is used to add cooling water to the water collection tank. Because the cooling water will be lost during the operation of the cooling tower, the water filling port can replenish the cooling water in the water collection tank, and there is a certain water pressure when the water filling port is discharged. The water pressure can push the particles to move toward the adsorption plate, making it easier for the adsorption plate to adsorb the particles. The water filling port is close to the adsorption plate, so that the distance between the water filling port and the adsorption plate is close, and the impact force of the water pressure impact on the adsorption plate is relatively large, so that more particles can be adsorbed by the adsorption plate.

[0020] The utility model is described in detail below in conjunction with the accompanying drawings and embodiments.

[0021] Long life cooling tower, such as Figure 1 and Figure 4 As shown, it includes a tower body 1, a water collecting tank 2 and a spray head located in the tower body 1, a spray pump 3 is fixedly connected to the outside of the tower body 1, the spray pump 3 includes an inlet end 4 connected to the water collecting tank 2 and an outlet end connected to the spray head, a filter screen 5 is provided in the water collecting tank 2 to wrap the inlet end 4, the filter screen 5 is used to limit the particles from entering the inlet end 4, an adsorption plate 6 for adsorbing particles is provided on one side wall of the water collecting tank 2, the inlet end 4 is arranged close to the adsorption plate 6, a water adding port 7 for adding water to the water collecting tank 2 is arranged in the water collecting tank 2, the water adding port 7 is close to the adsorption plate 6 and the water adding port 7 is aligned with the adsorption plate 6, when the cooling water in the water collecting tank 2 enters the inlet end 4, the filter screen 5 can separate the particles in the cooling water, so that the particles cannot enter the spray pump 3, thereby ensuring the safety of the spray pump 3 and the spray head, thereby ensuring the overall life of the spray head and the spray pump 3, because the inlet end In the process of absorbing cooling water, solid particles in the cooling water tend to gather near the inlet end 4. The adsorption plate 6 is arranged near the inlet end 4 so that the adsorption plate 6 can adsorb the solid particles, thereby reducing the movement of particles around the inlet end 4 and reducing the filtering pressure of the filter 5, so that the filter 5 is not easily blocked by particles. The water adding port 7 is used to add cooling water to the water collecting tank 2. Since the cooling water will be lost during the operation of the cooling tower, the water adding port 7 can replenish the cooling water in the water collecting tank 2, and there is a certain water pressure when the water adding port 7 is discharged. The water pressure can push the particles to move toward the adsorption plate 6, so that the adsorption plate 6 is easier to adsorb the particles. In addition, the water adding port 7 is close to the adsorption plate 6, so that the distance between the water adding port 7 and the adsorption plate 6 is close, and the impact force of the water pressure impact on the adsorption plate 6 is relatively large, so that more particles can be adsorbed by the adsorption plate 6.

[0022] like Figure 2 and Figure 3As shown, the filter screen 5 is located on the path from the water filling port 7 to the adsorption plate 6. This arrangement allows the impact force of the water flow to impact the filter screen 5 when water flows out of the water filling port 7, thereby causing the filter screen 5 to vibrate to a certain extent, so that some particles can be separated from the filter screen 5. A fixing frame 8 is bonded to the outer edge of the filter screen 5. The fixing frame 8 is provided with a threaded hole 9 for passing through by a fixing bolt. The fixing frame 8 is fixed to the side wall of the inlet end 4 of the water collection tank 2 by fixing bolts. People place the inlet end 4 at the center of the fixing frame 8, and use fixing bolts to fix the fixing frame 8 to the side wall of the inlet end 4 of the water collection tank 2, so that the filter screen 5 covers the inlet end 4. This arrangement is convenient In order for people to install and remove the filter screen 5, a fixing frame 10 with an L-shaped cross-section is fixed to one side wall of the water collecting tank 2 by bolts. The length direction of the fixing frame 10 is arranged along the depth direction of the water collecting tank 2. The distance from the side wall of the inlet end 4 of the water collecting tank 2 to the fixing frame 10 is equal to the width of the adsorption plate 6. When people need to install the adsorption plate 6, they insert the adsorption plate 6 between the fixing frame 10 and one side wall of the water collecting tank 2. Because the cross-section of the fixing frame 10 is L-shaped, the fixing frame 10 allows the adsorption plate 6 to always remain in contact with the inner wall of the water collecting tank 2, thereby ensuring the fixing strength of the adsorption plate 6. In addition, such an arrangement allows the adsorption plate 6 to be fixed by simple pulling and plugging, thereby facilitating people's operation.

[0023] like Figure 3 As shown, the adsorption plate 6 includes an adsorption portion 11 and a fixing portion 12 arranged along the outer edge of the adsorption portion 11, one side of the adsorption portion 11 is flush with one side of the fixing portion 12, and the other side of the adsorption portion 11 protrudes away from the fixing portion 12. This arrangement enables the end of the adsorption portion 11 facing the water filling port 7 to be more protruding, and the contact area between the protruding position of the adsorption portion 11 and the cooling water is increased, so that the adsorption portion 11 is easier to adsorb particles in the cooling water. A handle 13 is provided on one side of the fixing portion 12, and the handle 13 is provided to provide a fulcrum for people to pull out the adsorption plate 6 from between the fixing frame 10 and the inner wall of the water collecting tank 2, so that people can pull out the adsorption plate 6 more labor-saving. The adsorption portion 11 is made of activated carbon. The porous structure of the activated carbon makes it have a rich surface area, which is conducive to the adsorption and fixation of particulate matter. There are abundant active functional groups on the surface of the activated carbon, such as hydroxyl, carboxyl, etc. These functional groups can undergo chemical adsorption or electrostatic action with the particulate matter, increase the ability to adsorb particles, and ensure the adsorption effect of the adsorption portion 11.

All technical solutions under the concept of the present invention belong to the protection scope of the present invention. It should be pointed out that for ordinary technicians in this technical field, some improvements and modifications without departing from the principle of the present invention should also be regarded as the protection scope of the present invention.
