Description

Technical Field

[0001] This invention relates to the field of cooling tower technology, and specifically to a cooling tower. Background Technology

[0002] Cooling towers are structures used to cool water and are widely used in power plants, chemical plants, cement plants, and other factories that require large-scale water temperature control. Inside a cooling tower, arranged from top to bottom, are a fan, demister, spray system, heat dissipation packing, and a cold water tank. The working principle of a standard cooling tower is as follows: hot water is injected into the spray system through pipes. An air inlet is located at the bottom of the cooling tower, below the heat dissipation packing. Outside air enters the cooling tower through this inlet, creating convection between the air blowing in from the bottom and the hot water sprayed downwards. Some of the water evaporates during this convection, carrying away the latent heat of vaporization and thus lowering the water temperature. During this convective heat exchange process, liquid droplets are generated. These droplets are carried away by the airflow, then collected by the demister. Finally, the air is discharged into the atmosphere by the fan at the top of the cooling tower.

[0003] Currently, the cooling tower only relies on a spray system to spray hot water from top to bottom, which causes the air blown in from the bottom of the cooling tower to form convection with the hot water and lower the temperature of the hot water. However, the cooling range of the hot water is limited and the cooling efficiency is low. Moreover, during the convection contact heat exchange process, a large amount of water is evaporated and consumed, resulting in a serious waste of water resources. Summary of the Invention

[0004] (I) The problem to be solved by the present invention is that the current cooling towers rely solely on the spray mechanism to spray hot water from top to bottom, so that the air blown in from the bottom of the cooling tower forms convection with the hot water to reduce the temperature of the hot water. The cooling range of the hot water is limited, the cooling efficiency is also low, and a large amount of water is evaporated and consumed during the convection contact heat exchange process, resulting in a serious waste of water resources.

[0021] According to one embodiment of the present invention, the first side end of the first fin is lower than the second side end, the second fin intersects with the first fin, or the second fin and the first fin are parallel.

[0022] According to one embodiment of the present invention, the first fin is perpendicular to the axis of the tower body, and the second fin intersects with the first fin.

[0023] According to one embodiment of the present invention, a plurality of support plates are provided, the plurality of support plates are arranged along the length direction of the first fin, and a ventilation gap is formed between two adjacent support plates.

[0025] Two demisters are installed on the side of each straight pipe. The demisters are arranged along the length of the straight pipe, and the two demisters are symmetrical about the axis of the straight pipe.

[0026] According to one embodiment of the present invention, a plurality of demisting cooling components are provided, and the plurality of demisting cooling components are installed in the cavity of the tower body in descending order. The water inlet of the coil in the topmost demisting cooling component is connected to one end of the water supply pipe, and the water outlet of the coil in the bottommost demisting cooling component is connected to the spraying component through a pipe.

[0027] In two adjacent demisting cooling assemblies, the water outlet of the coil in one demisting cooling assembly is connected to the water inlet of the coil in the other demisting cooling assembly via a water outlet pipe.

[0028] According to one embodiment of the present invention, the spraying assembly includes a water spray pipe mechanism and a plurality of nozzles, wherein a plurality of water holes are uniformly formed on the lower surface of the water spray pipe mechanism, and at least one nozzle is installed in each of the water holes.

[0029] The beneficial effects of this invention are:

[0030] This invention provides a cooling tower, comprising a tower body, a cold water tank, heat dissipation packing, a spray assembly, at least one demisting cooling assembly, a fan, and a water supply pipe. The tower body has an internal cavity, and at least one air inlet is provided on the side wall of the tower body, communicating with the cavity. The top of the tower body has a gas outlet, which is also connected to the cavity. The fan, demisting cooling assembly, spray assembly, and heat dissipation packing are installed sequentially within the cavity in descending order of height. The cold water tank is formed at the bottom of the cavity, and the air inlet is located below the heat dissipation packing and the cold water tank. One end of the water supply pipe... The water inlet of the demisting cooling component is connected to the water outlet of the spray component; the water supply pipe is used to deliver hot water into the demisting cooling component, the demisting cooling component is used to cool the hot water delivered by the water supply pipe and deliver the cooled hot water to the spray component; the spray component is used to spray the hot water delivered by the demisting cooling component; the hot water sprayed by the spray component convects with the air entering the cavity from the air inlet to generate mist, and the demisting cooling component is also used to capture the mist; the fan is used to draw the gas in the cavity to the gas outlet at the top of the cavity.

[0031] When the cooling tower is working, hot water is injected into the demisting cooling component through the water supply pipe. The demisting cooling component performs initial cooling of the hot water, i.e., precooling. The precooled hot water is then transported to the spray component, which sprays the precooled hot water from top to bottom. At the same time, outside air enters the tower from the air inlet at the bottom of the tower. The air blowing in from the bottom of the cooling tower forms convection with the hot water sprayed from top to bottom. Some of the water evaporates in the convection, carrying away the corresponding latent heat of vaporization, thereby lowering the water temperature. The sprayed water droplets fall onto the heat dissipation packing and finally drip into the cold water pool.

[0032] During the convective heat exchange process, liquid droplets are carried by the airflow toward the top of the tower. When the liquid droplets pass through the demisting cooling component, the demisting cooling component captures the mist.

[0033] Compared to traditional cooling towers, the cooling tower in this embodiment has at least the following advantages:

[0034] First, unlike traditional demisters, this demister cooling component not only has a demister function, but can also cool hot water. When combined with the spray component, it can improve the cooling effect and cooling efficiency.

[0035] Secondly, the demisting cooling component performs initial cooling, and then the spray component sprays the hot water that has undergone initial cooling. In this way, since the hot water is cooled once and then convects with the air blown in from the bottom of the cooling tower, the cooling effect is ensured while greatly reducing water consumption.

Detailed Implementation

[0046] The technical solution of the present invention will be clearly and completely described below with reference to the embodiments. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0047] like Figures 1-8As shown, one embodiment of the present invention provides a cooling tower, including a tower body 1, a cold water pool 2, heat dissipation packing 3, a spray assembly 6, at least one demisting cooling assembly 5, a fan 4, and a water supply pipe 7.

[0048] The tower body 1 has an internal cavity, and at least one air inlet 101 is provided on the side wall of the tower body 1. The air inlet 101 is connected to the cavity, and the top of the tower body 1 has a gas outlet, which is connected to the cavity.

[0049] The fan 4, the demisting cooling component 5, the spray component 6 and the heat dissipation filler 3 are installed in the cavity in order from high to low. The cold water pool 2 is formed at the bottom of the cavity, and the air inlet 101 is located below the heat dissipation filler 3 and the cold water pool 2.

[0050] One end of the water supply pipe 7 is connected to the water inlet of the demisting cooling component 5, and the water outlet of the demisting cooling component 5 is connected to the spray component 6.

[0051] The water supply pipe 7 is used to supply hot water into the demisting cooling assembly 5, and the demisting cooling assembly 5 is used to cool the hot water supplied by the water supply pipe 7 and transport the cooled hot water to the spray assembly 6.

[0052] The spray assembly 6 is used to spray the hot water supplied by the demisting and cooling assembly 5;

[0053] The hot water sprayed by the spray assembly 6 convects with the air entering the cavity from the air inlet to generate mist. The demisting and cooling assembly 5 is also used to capture the mist.

[0054] Fan 4 is used to draw the gas inside the cavity to the gas outlet at the top of the cavity.

[0055] When the cooling tower is working, hot water is injected into the demisting cooling component 5 through the water supply pipe 7. The demisting cooling component 5 performs initial cooling of the hot water, i.e., pre-cooling. The pre-cooled hot water is then transported to the spray component 6, which sprays the pre-cooled hot water from top to bottom. At the same time, outside air enters the interior of the tower 1 through the air inlet 101 at the bottom of the tower body 1. The air blown in from the bottom of the cooling tower forms convection with the hot water sprayed from top to bottom. Some of the water evaporates in the convection, carrying away the corresponding latent heat of vaporization, thereby lowering the water temperature. The sprayed water droplets fall onto the heat dissipation packing 3 and finally drip into the cold water pool 2.

[0056] During the convective contact heat exchange process, liquid droplets are carried by the airflow toward the top of the tower body 1. When the liquid droplets pass through the demisting cooling component 5, the demisting cooling component 5 captures the mist.

[0057] Compared to traditional cooling towers, the cooling tower in this embodiment has at least the following advantages:

[0058] First, unlike traditional demisters, this demister cooling component 5 not only has a demister function, but can also cool hot water. When combined with the spray component 6, it can improve the cooling effect and cooling efficiency.

[0059] Secondly, in the process of convective heat exchange, the high temperature of the hot water sprayed by the spray mechanism in traditional cooling towers leads to the evaporation and consumption of a large amount of water, resulting in a serious waste of water resources.

[0060] In this embodiment, the defogging cooling component 5 performs initial cooling first, and then the spray component 6 sprays the hot water that has undergone initial cooling. In this way, since the hot water is cooled once and then convects with the air blown in from the bottom of the cooling tower, the cooling effect is ensured while the water consumption is greatly reduced.

[0061] Preferred, such as Figure 1 and Figure 2 As shown, the demisting cooling assembly 5 includes a coil 8 and multiple demisting components 9. A water inlet pipe 10 is installed at the water inlet of the coil 8, and a water outlet pipe 11 is installed at the water outlet of the coil 8. One end of the water supply pipe 7 is connected to the water inlet pipe 10, and one end of the water outlet pipe 11 is connected to the spray assembly 6. Multiple demisting components 9 are installed on the coil 8 and are used to dissipate heat from the coil 8 and to capture mist.

[0062] The water supply pipe 7 delivers hot water to the inlet pipe 10. After flowing through the inlet pipe 10, the hot water flows into the coil 8. During the flow of hot water, the temperature of the hot water decreases as the demister 9 is used to dissipate heat from the coil 8. The pre-cooled hot water flows out from the outlet pipe 11 into the spray assembly 6, which sprays the pre-cooled hot water.

[0063] Preferred, such as Figure 2 As shown, the coil 8 includes multiple straight pipes 801 and multiple elbow pipes 802. Two adjacent straight pipes 801 are connected by elbow pipes 802. The demisting element 9 is installed on the straight pipes 801 along the length of the straight pipes 801.

[0064] The demisting component 9 includes a first fin 901, a second fin 903, and at least one support plate 902. Both the first fin 901 and the second fin 903 are in the shape of long strips, and the lengths of the first fin 901 and the second fin 903 are approximately the same as the length of the straight tube 801.

[0065] The first side end of the first fin 901 is welded to the side of the coil 8. The second fin 903 is higher than the first fin 901. The bottom end of the support piece 902 is welded to the upper surface of the first fin 901, and the top end of the support piece 902 is welded to the lower surface of the second fin 903. A ventilation channel is formed between the first fin 901 and the second fin 903.

[0066] Since the first fin 901, the second fin 903, and the support fin 902 are all heat dissipation fins, they can be made of copper, aluminum alloy, or brass. In this embodiment, copper is preferred.

[0067] The hot water flowing through the straight pipe 801 will make the temperature of the straight pipe 801 relatively high. The first fin 901 dissipates heat from the straight pipe 801. The heat on the first fin 901 is conducted to the support plate 902, and then the heat is conducted to the second fin 903 through the support plate 902. In this way, the heat dissipation of the straight pipe 801 can be quickly achieved through the first fin 901, the second fin 903 and the support plate 902, thereby initially cooling the hot water in the straight pipe 801.

[0068] In a preferred embodiment, the first side end of the first fin 901 is higher than the second side end of the first fin 901. The first fin 901 is obliquely welded to the straight tube 801. The first side end of the second fin 903 is located directly above the first fin 901. The downward projection of the second side end of the second fin 903 does not fall onto the first fin 901. The bottom end of the support piece 902 is welded to the right end of the first fin 901, and the top end of the support piece 902 is welded to the second fin 903 near its first side end. The first side end of the second fin 903 is higher than its second side end, meaning the second fin 903 is also oblique, and it is parallel to the first fin 901.

[0069] Furthermore, multiple support plates 902 are provided, arranged sequentially along the length of the first fin 901, and ventilation gaps are formed between adjacent support plates 902. Specifically, the distance between adjacent support plates 902 is the same, that is, the support plates 902 are uniformly welded to the first fin 901, so the length of the ventilation gap is fixed.

[0070] Outside air enters the interior of tower 1 through the air inlet 101 at the bottom of tower 1. The air blown in from the bottom of the cooling tower forms convection with the hot water sprayed from above. Some of the water evaporates in the convection, taking away the corresponding latent heat of vaporization, thereby lowering the water temperature. During the convective heat exchange process, liquid droplets are carried by the airflow toward the demisting cooling component 5. The gas containing liquid mist flows through the demisting cooling component 5 at a certain speed. Due to the inertial impact of the gas, the droplets collide with the first fin 901 and the second fin 903 and are collected. When the droplets become so large that their own gravity exceeds the resultant force of the gas's upward force and the liquid's surface tension, the droplets are separated from the surfaces of the first fin 901 and the second fin 903.

[0071] Furthermore, since the first side end of the first fin 901 is higher than the second side end of the first fin 901, and the first side end of the second fin 903 is located directly above the first fin 901, the downward projection of the second side end of the second fin 903 does not fall onto the first fin 901. Thus, the gas bypasses the first fin 901, and because some of the gas is blocked by the second fin 903, it flows out from the ventilation channel between the first fin 901 and the second fin 903. Further, since the first side end of the second fin 903 is higher than the second side end of the second fin 903 (i.e., the second fin 903 is also inclined) and parallel to the first fin 901, some of the gas is directly blocked by the second fin 903 and enters the ventilation channel along the lower surface of the second fin 903.

[0072] It should be noted that setting the first fin 901 and the second fin 903 in an inclined state is more conducive to the aggregation of droplets, thereby accelerating the separation rate of droplets and also making it more conducive to the rapid rise and discharge of gas.

[0073] Specifically, such as Figure 4 In the middle, a demisting element 9 located on the right side of the straight pipe 801 is shown. The left end of the first fin 901 is welded to the straight pipe 801, and the left end of the first fin 901 is lower than its right end, while the left end of the second fin 903 is higher than the right end of the second fin 903, and the first fin 901 and the second fin 903 are parallel.

[0074] Preferred, Figure 4 As shown, two demisters 9 are welded onto each straight pipe 801. The two demisters 9 are symmetrically arranged about the axis of the straight pipe 801, with one demister 9 welded to the left side of the straight pipe 801 and the other demister 9 welded to the right side. This makes full use of the space, maximizes the collection area, and improves the fog collection efficiency.

[0075] In the demister 9 located on the left side of the straight tube 801, the right side of the first fin 901 is welded to the straight tube 801. The right end of the first fin 901 is higher than the left end of the first fin 901, while the right end of the second fin 903 is higher than the left end of the second fin 903. The second fin 903 and the first fin 901 are parallel.

[0076] As an alternative embodiment, Figure 5This is a second structural diagram of the straight pipe 801 and the demister 9. A demister 9 is welded to each of the two sides of the straight pipe 801. The difference from the previous embodiment is that in this embodiment, in the demister 9 located on the left side of the straight pipe 801, the right end of the first fin 901 is welded to the left side of the straight pipe 801, and the right end of the first fin 901 is lower than its left end. Conversely, the left end of the second fin 903 is lower than its right end. The first fin 901 and the second fin 903 intersect.

[0077] When the mist-containing gas located directly below the first fin 901 impacts the first fin 901, the gas rises along the first fin 901 without needing to bypass it. Due to the obstruction of the second fin 903, the gas further enters the ventilation channel along the second fin 903. This allows the gas to enter the ventilation channel and be discharged more quickly and smoothly.

[0078] As an alternative embodiment, Figure 6 The diagram shows a third structure of a straight tube 801 and a demister 9. A demister 9 is welded to each side of the straight tube 801. In the demister 9 located on the left side of the straight tube 801, the right end of the first fin 901 is welded to the straight tube 801, and the right end of the first fin 901 is higher than the left end of the first fin 901. The left end of the second fin 903 is higher than the right end of the second fin 903.

[0079] In the demister 9 located on the right side of the straight pipe 801, the left end of the first fin 901 is welded to the straight pipe 801, the left end of the first fin 901 is higher than the right end of the first fin 901, and the left end of the second fin 903 is lower than its right end.

[0080] In this way, the mist-containing gas located directly below the first fin 901 impacts the first fin 901, then the gas bypasses the first fin 901 and is directly discharged along the second fin 903, without needing to enter the ventilation channel, resulting in a faster gas flow rate.

[0081] As an alternative embodiment, Figure 7 The diagram shows a fourth structure of a straight tube 801 and a demister 9. A demister 9 is welded to each side of the straight tube 801. In the demister 9 located on the left side of the straight tube 801, the right end of the first fin 901 is welded to the left side of the straight tube 801, and the right end of the first fin 901 is lower than the left end of the first fin 901. The left end of the second fin 903 is lower than the right end of the second fin 903.

[0082] In the demister 9 located on the right side of the straight pipe 801, the left end of the first fin 901 is welded to the straight pipe 801. The left end of the first fin 901 is lower than the right end of the first fin 901, while the right end of the second fin 903 is higher than the left end of the second fin 903. The first fin 901 and the second fin 903 are in an intersecting state.

[0083] This maximizes the gas discharge rate, accelerates gas processing efficiency, and thus speeds up air circulation within tower 1.

[0084] As an alternative embodiment, Figure 8 The fifth structural diagram shows the straight tube 801 and the demister 9. The two demisters 9 are symmetrically arranged about the straight tube 801. Taking the demister 9 located on the right side of the straight tube 801 as an example, the first fin 901 is in a horizontal state, while the left end of the second fin 903 is higher than the right end of the second fin 903.

[0085] Optional, such as Figure 2 As shown, a connecting rod 803 is welded to each elbow pipe 802. One end of the connecting rod 803 is fixed to the inner wall of the tower body 1, thereby fixing the demisting cooling component 5.

[0086] Optionally, the sprinkler assembly 6 includes a sprinkler pipe mechanism and multiple nozzles. The sprinkler pipe mechanism includes a main pipe and multiple branch pipes. Multiple water inlets are formed along the length of the main pipe, with each inlet corresponding to a branch pipe. One end of each branch pipe is sealed to a water inlet, and the other end is also sealed. Multiple water holes are evenly distributed on the lower surface of each branch pipe, and a nozzle is installed in each water hole. The main pipe and the coil 8 are connected via a water outlet pipe 11.

[0087] Of course, the spray assembly 6 can also adopt other pipe layout designs, and no specific restrictions are imposed here.

[0088] Optionally, there are two defogging cooling components 5. For ease of description, one defogging cooling component 5 is named the first defogging cooling component, and the other defogging cooling component 5 is named the second defogging cooling component.

[0089] The first demisting cooling component is positioned above the second demisting cooling component. One end of the water supply pipe 7 is connected to the water inlet pipe 10 on the coil 8 in the first demisting cooling component. The water outlet of the coil 8 in the first demisting cooling component is connected to the water inlet of the coil 8 in the second demisting cooling component through the water outlet pipe 11. The water outlet of the second demisting cooling component is connected to the main pipe of the spray component 6 through a pipe.

[0090] In this way, the hot water can continuously pass through two demisting cooling components 5. The two demisting cooling components 5 cool the hot water in turn, which can further improve the cooling effect of the hot water and accelerate the cooling efficiency. In addition, the two sets of demisting cooling components 5 can fully capture the mist, saving water resources.
