Description

Technical Field

[0001] The utility model relates to the technical field of circulating water cooling, and more specifically to a V-shaped closed cooling tower. Background Art

[0002] A large amount of heat is generated during industrial production, and a circulating water cooling system is usually used for cooling. Existing circulating water cooling systems include wet cooling, dry cooling, and other forms. Among them, the dry cooling system has obvious advantages in water saving, but the cooling capacity is greatly affected by the ambient dry bulb temperature, especially under high temperature conditions in summer. Due to the particularity of the water temperature range requirements of some process systems, the heat dissipation capacity of the dry cooling system is severely limited. If combined with wet cooling, it can meet the water temperature requirements of process equipment and save evaporation water consumption.

[0003] At present, the vast majority of applications in the field of industrial circulating water are wet cooling and dry cooling towers, and the conventional dry cooling towers generally have heat exchange tube bundles arranged vertically or sideways, which occupy a large area under the same heat exchange area. Since most industrial circulating water industries have the characteristics of large industrial scale, large circulating water volume, high heat dissipation demand and tight land conditions, this field tends to adopt wet cooling and dry cooling stacked tower arrangements as a replacement.

[0004] The main deficiencies of the existing circulating water dry-wet combined cooling technology are:

[0005] (1) The cooling tower occupies a large area, and the fans are small in diameter and numerous in number, resulting in high maintenance and operating costs;

[0006] (2) The huge noise generated by the operation of a large number of fans will also bring adverse environmental impacts.

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0041] The core of the utility model is to provide a V-shaped closed cooling tower, which can reduce the consumption of evaporation water, reduce operating noise, and stabilize the quality of circulating water.

[0042] Please refer to Figures 1 to 4 , Figure 1 This is a schematic diagram of the first structure of a V-shaped closed cooling tower provided by the utility model; Figure 2 for Figure 1 Side view of Figure 3 A second structural schematic diagram of a V-shaped closed cooling tower; Figure 4 for Figure 3 Side view of.

[0043] This specific embodiment provides a V-shaped closed cooling tower, comprising:

[0044] The dry cooling section radiator 1 comprises one or more cooling tube bundles arranged in a V shape;

[0045] The dry cooling section fan unit 2 is arranged on the top of the dry cooling section radiator 1 so that the ambient cold air passes through the cooling tube bundle;

[0046] A dry cooling section support structure 3, which is used to install the dry cooling section radiator 1 and the dry cooling section fan unit 2;

[0047] A cooling tower body 7, with a dry cooling section support structure 3 provided on the top;

[0048] The V-shaped closed cooling tower is connected to one or more water-using equipment, and the water-using equipment is connected to the dry cooling section radiator 1 through a pipeline assembly 8.

[0049] It should be noted that the dry cooling section radiator 1 can be set on the top of the cooling tower body 7, the dry cooling section fan unit 2 can be set on the top of the dry cooling section radiator 1, and the dry cooling section support structure 3 is used to support the dry cooling section radiator 1 and the dry cooling section fan unit 2.

[0050] In actual use, the shape, structure, size, material, position, etc. of the dry cooling section radiator 1, the dry cooling section fan unit 2, the dry cooling section support structure 3 and the cooling tower body 7 can be determined according to actual conditions and actual needs.

[0051] When the V-shaped closed cooling tower provided by the utility model is used, the high-temperature circulating water of the water-using equipment enters the dry cooling section radiator 1 through the pipe assembly 8, and the dry cooling section fan unit 2 provides power to make the ambient cold air pass through the cooling tube bundle of the dry cooling section radiator 1 to take away the heat of the circulating water, thereby achieving the effect of lowering the circulating water temperature. The cooled circulating water flows back to the water-using equipment through the pipe assembly 8 to complete the circulation cooling.

[0052] This device makes full use of the dry cooling section radiator 1 to remove the heat load, which can reduce the evaporation water consumption of the wet cooling section and achieve the purpose of water saving. In addition, the cooling tube bundle of the dry cooling section radiator 1 is usually arranged vertically or sideways. However, the dry cooling section radiator 1 of this device adopts an upright inclined arrangement (that is, the cooling tube bundle is arranged in a V shape). Under the same floor space conditions, the V-shaped arrangement of the cooling tube bundle can expand the heat exchange area of ​​the dry cooling section radiator 1, thereby obtaining a higher dry point, that is, a greater cooling capacity. At the same time, the operation of the dry cooling section fan unit 2 can be reduced, reducing the noise pollution generated by the operation of a large number of fans. In addition, this device is a closed circulation structure, that is, the circulating water does not come into contact with the air, which makes it easy to ensure the water quality and improve the safety and reliability of equipment operation.

[0053] In summary, the V-shaped closed cooling tower provided by the utility model can reduce the consumption of evaporative water, reduce operating noise, and stabilize the quality of circulating water.

[0054] In one embodiment, it also includes a wet cooling section heat sink 4, a wet cooling section shutter 5 and a water collecting pool 6, wherein the wet cooling section heat sink 4 is arranged in the middle of the cooling tower body 7, the water collecting pool 6 is arranged at the bottom of the cooling tower body 7, and the wet cooling section shutter 5 is located between the wet cooling section heat sink 4 and the water collecting pool 6;

[0055] The dry cooling section radiator 1 is located on the top of the wet cooling section radiator 4, and the dry cooling section radiator 1 is connected to the wet cooling section radiator 4 through a pipe assembly 8. The structure is as follows: Figure 3 , 4 shown.

[0056] It should be noted that the dry cooling section (including the dry cooling section radiator 1 and the dry cooling section fan unit 2, etc.) and the wet cooling section (including the wet cooling section heat dissipation device 4, the wet cooling section shutter 5 and the water collection tank, etc.) of the V-shaped closed cooling tower can be operated in combination to fully utilize the dry cooling section to remove the heat load, reduce the evaporation water consumption of the wet cooling section, and achieve the purpose of water saving. In addition, the opening of the wet cooling section shutter 5 can be adjusted according to the ambient temperature to match the cooling capacity of the wet cooling section heat dissipation device 4.

[0057] When the ambient temperature is low, the wet cooling section is not turned on, and heat is mainly dissipated through the dry cooling section without consuming water. When the ambient temperature is high, the wet cooling section is turned on, the air intake of the wet cooling section is increased, and the air intake of the dry cooling section is reduced. The dry cooling section and the wet cooling section are jointly operated in a water-saving manner to meet the circulating water outlet temperature during the high temperature period in summer.

[0058] Moreover, the hot and humid air heated by the wet cooling section is mixed with the incoming air of the dry cooling section to form unsaturated air, and then heat is exchanged with the dry cooling section to avoid the generation of white fog at the tower outlet and achieve the purpose of defogging.

[0059] In one embodiment, the pipeline assembly 8 includes a circulating water inlet pipeline 8.1 and a circulating water return pipeline 8.2; the water-using equipment is connected to the water inlet of the circulating water inlet pipeline 8.1, the water outlet of the circulating water inlet pipeline 8.1 is connected to the water inlet of the dry cooling section radiator 1, the water outlet of the dry cooling section radiator 1 is connected to the water inlet of the wet cooling section heat dissipation device 4 through a pipeline, the water outlet of the wet cooling section heat dissipation device 4 is connected to the water inlet of the circulating water return pipeline 8.2, and the water outlet of the circulating water return pipeline 8.2 is connected to the water-using equipment.

[0060] It should be noted that if the V-shaped closed cooling tower only includes the dry cooling section radiator 1 and the dry cooling section fan unit 2, the structure is as follows: Figure 1 , 2 At this time, the high-temperature circulating water of the water-using equipment can enter the dry cooling section radiator 1 through the circulating water inlet pipe 8.1, and the dry cooling section fan unit 2 provides power to allow the ambient cold air to pass through the dry cooling section radiator 1, taking away the heat of the circulating water, thereby achieving the effect of lowering the circulating water temperature. The cooled circulating water flows back to the water-using equipment through the circulating water return pipe 8.2, completing the circulation cooling.

[0061] In addition, it should be noted that if the V-shaped closed cooling tower only includes a dry cooling section radiator 1, a dry cooling section fan unit 2, a wet cooling section heat dissipation device 4, a wet cooling section shutter 5 and a water collection tank 6, the structure is as follows Figure 3 , 4As shown. At this time, the high-temperature circulating water of the water-using equipment enters the dry cooling section radiator 1 through the circulating water inlet pipe 8.1, and is powered by the dry cooling section fan unit 2, so that the ambient cold air passes through the dry cooling section radiator 1, taking away the heat of the circulating water, thereby achieving the effect of lowering the temperature of the circulating water. The cooled circulating water enters the wet cooling section heat sink 4 again through the pipe assembly 8, and is cooled by the wet cooling section heat sink 4, taking away the heat of the circulating water, thereby achieving the effect of further cooling. The cooled circulating water flows back to the water-using equipment through the circulating water return pipe 8.2, completing the circulation cooling.

[0065] Therefore, the transmission power of the dry cooling section motor 2.2 can be transmitted to the dry cooling section fan 2.1 through the dry cooling section reducer 2.3, so that the dry cooling section fan 2.1 can operate normally. In actual use, the types of the dry cooling section motor 2.2, the dry cooling section reducer 2.3, the dry cooling section fan 2.1 and the dry cooling section air duct 2.4 can be determined according to actual conditions and actual needs.

[0068] It should be noted that the wet cooling section heat dissipation device 4 may include one or more wet cooling heat dissipation devices; the wet cooling heat dissipation device includes a wet cooling section fan unit 4.1, a wet cooling tube bundle 4.2, a wet cooling tube bundle frame 4.3 and a spray system 4.4.

[0069] The high-temperature circulating water of the water-using equipment enters the dry cooling section radiator 1 through the circulating water inlet pipe 8.1, and is powered by the dry cooling section fan unit 2, so that the ambient cold air passes through the dry cooling section radiator 1, taking away the heat of the circulating water, thereby achieving the effect of lowering the circulating water temperature. The cooled circulating water enters the wet cooling tube bundle 4.2 again through the pipe assembly 8, and through the wet cooling section fan unit 4.1 and the spray system 4.4, the heat of the circulating water is taken away again through water film evaporation, thereby achieving the effect of further cooling. The cooled circulating water flows back to the water-using equipment through the circulating water outlet pipe 8.2, completing the circulation cooling.

[0070] In one embodiment, the wet cooling section fan unit 4.1 includes a wet cooling section motor 4.1.3, a wet cooling section reducer 4.1.4 connected to the wet cooling section motor 4.1.3, a wet cooling section fan 4.1.1 connected to the wet cooling section reducer 4.1.4, and a wet cooling section air duct 4.1.2 disposed outside the wet cooling section fan 4.1.1;

[0074] In one embodiment, the opening of the wet and cold section shutter 5 is adjustable, or the opening of the wet and cold section shutter 5 is fixed. That is, the wet and cold section shutter 5 can automatically adjust the opening independently according to the outlet water temperature, or the wet and cold section shutter 5 is set to a fixed opening.

[0075] In one embodiment, the cooling tower body 7 includes a concrete structure or a steel structure.

[0076] The dry cooling section and the wet cooling section of the V-shaped closed cooling tower provided by the utility model are operated in combination, making full use of the dry cooling section to remove the heat load, reducing the evaporation water consumption of the wet cooling section, and achieving the purpose of water saving; the opening of the wet cooling section shutter 5 can be adjusted according to the ambient temperature to match the cooling capacity of the wet cooling section.

[0078] When the ambient temperature is high, the dry-wet combined operation mode is adopted: that is, when the dry cooling section fan unit 2 is running at the highest speed, the return water temperature is still higher than the water temperature, then the wet cooling section fan unit 4.1 and the spray system 4.4 are turned on, and the opening of the wet cooling section shutter 5 and the speed of the wet cooling section fan unit 4.1 are gradually increased, so that the circulating water temperature in the circulating water return pipe 8.2 reaches the target value.
