Description

Technical Field

[0001] This utility model relates to the field of cooling tower technology, and in particular to a water vapor recovery device for energy-saving and defogging cooling towers. Background Technology

[0002] A cooling tower is a device used in industrial and building cooling systems. Its main function is to lower water temperature through evaporation. In many industrial sectors, especially large-scale facilities such as power plants, chemical plants, and air conditioning systems, it is necessary to cool hot water in equipment or factories to maintain normal operation. During the evaporation process in a cooling tower, some water is released into the air as water vapor. This water vapor can have environmental impacts in certain situations, particularly in areas with high humidity or industrial sites near residential areas. To reduce this impact, modern cooling towers are designed with measures to recover this water vapor or mist.

[0003] Chinese patent discloses a water vapor recovery device for a fog-removing cooling tower (publication number CN222012779U). This patented technology introduces hot and humid gas into the condensing chamber through a gas guiding mechanism. After passing through heat exchange plates, the gas is cooled and condensed. The condensed water falls into the lower part of the condensing chamber and flows into the water collection tank, thus completing the recovery of water vapor and facilitating the recycling of water resources.

[0004] However, most existing cooling towers directly introduce water vapor into the condensation chamber for condensation via heat exchange fins. This method fails to slow down the incoming water vapor, resulting in rapid vapor flow and reduced condensation efficiency. For example, the aforementioned prior art uses a method of directly introducing water vapor into the condensation chamber. In practical applications, when water vapor is directly introduced into the cooling chamber, its high fluidity causes it to escape before fully condensing, thus affecting the recovery effect. Therefore, those skilled in the art provide a water vapor recovery device for energy-saving, defogging cooling towers to address the problems mentioned in the background section. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a water vapor recovery device for energy-saving defogging cooling towers, solving the problems mentioned in the background section.

[0006] To achieve the above objectives, this utility model provides the following technical solution: A water vapor recovery device for an energy-saving defogging cooling tower, comprising: a recovery box, inside which a cooling box is installed, a condenser pipe is installed through the upper surface of the cooling box, one end of the condenser pipe is connected to an air inlet pipe, an outlet pipe is installed through the outer side of the cooling box, and the recovery box is installed outside the cooling box, a liquid pump is installed on both the front and rear surfaces of the recovery box, the outlet end of the liquid pump is connected to a drain pipe, the rear end of the drain pipe is connected to a spray pipe inside the recovery box, nozzles are symmetrically arranged on the rear surface of the spray pipe, a speed reduction plate is also installed inside the cooling box, and a material discharge plate is installed below the speed reduction plate inside the cooling box, and a filter screen is installed below the speed reduction plate on the inner side of the cooling box.

[0007] As a further technical solution of this utility model, the condenser tube is arranged in a "U" shape inside the recovery box, and the upper end of the air inlet pipe penetrates through the upper surface of the recovery box.

[0008] As a further technical solution of this utility model, the upper surface of the speed reduction plate is provided with speed reduction holes, and the filter screen is made of stainless steel and contacts the inside of the cooling box.

[0009] As a further technical solution of this utility model, the feeding plate is inclined inside the cooling box, and a heat-conducting rod is provided through the outside of the cooling box.

[0010] As a further technical solution of this utility model, the inside of the recycling tank is provided with cooling water, and the inlet end of the liquid pump is connected to a liquid extraction pipe inside the recycling tank.

[0011] As a further technical solution of this utility model, the drain pipe is L-shaped, and at least six nozzles are symmetrically arranged on the rear surface of the nozzle.

[0012] This utility model provides a water vapor recovery device for energy-saving defogging cooling towers, which has the following advantages compared with the prior art:

[0013] 1. This design provides a water vapor recovery device for energy-saving defogging cooling towers. Water vapor from the cooling tower can be introduced into the cooling tank inside the recovery tank through the air inlet pipe and condenser pipe. During the entry, a liquid pump can be used to extract the cooling water inside the recovery tank through the liquid extraction pipe and enter the spray pipe through the drain pipe. Finally, the water vapor inside the condenser pipe is sprayed out through the nozzle to condense the water vapor, thereby improving the water vapor recovery efficiency.

[0014] 2. This design provides a water vapor recovery device for energy-saving defogging cooling towers. A speed-reducing plate inside the cooling tank slows down the water vapor entering the recovery tank. Since the cooling tank is located inside the recovery tank and in contact with the cooling water, the water vapor inside the cooling tank can be condensed and recovered. Simultaneously, a heat-conducting rod is used to transfer the energy of the cooling water to the inside of the cooling tank, achieving better condensation recovery. A filter screen is used to filter impurities from the condensate, making it highly practical. Attached Figure Description

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0021] Please see Figure 1-4This utility model provides a technical solution for a water vapor recovery device for an energy-saving defogging cooling tower: It includes a recovery tank 1, inside which a cooling tank 5 is installed. A condenser pipe 21 is installed through the upper surface of the cooling tank 5, with one end of the condenser pipe 21 connected to an air inlet pipe 2. A liquid outlet pipe 4 is installed through the outer side of the cooling tank 5, and the recovery tank 1 is installed outside the cooling tank 5. A liquid pump 3 is installed on both the front and rear surfaces of the recovery tank 1. The outlet end of the liquid pump 3 is connected to a drain pipe 31. The rear end of the drain pipe 31 is connected to a spray pipe 32 inside the recovery tank 1. The rear surface of the cooling tank 5 is symmetrically equipped with nozzles 321. The cooling tank 5 is also equipped with a speed reduction plate 51. The cooling tank 5 is equipped with a feed plate 53 below the speed reduction plate 51. The cooling tank 5 is equipped with a filter screen 54 below the speed reduction plate 51 on the inner side. This arrangement allows the water vapor of the cooling tower to be introduced into the condenser tube 21 through the air inlet pipe 2. The cooling water sprayed by the nozzles 321 can achieve the purpose of condensing the water vapor in the condenser tube 21. The cooling tank 5 can also slow down the condensation of the incoming water vapor, thereby improving its condensation recovery effect and making it practical.

[0022] like Figure 2 and Figure 3 As shown, the condenser pipe 21 is arranged in a "U" shape inside the recovery box 1. The upper end of the air inlet pipe 2 penetrates the upper surface of the recovery box 1. This arrangement connects the condenser pipe 21 to the steam discharge port of the cooling tower. In this way, when the water vapor is discharged from the cooling tower, the water vapor will enter the condenser pipe 21 through the air inlet pipe 2 for condensation, and then enter the cooling box 5 through the condenser pipe 21 for condensation, thereby improving its condensation effect.

[0023] like Figure 2 As shown, the upper surface of the speed reduction plate 51 is provided with speed reduction holes, and the filter screen 54 is made of stainless steel and contacts the inside of the cooling box 5. This setting can reduce the flow rate of water vapor inside the cooling box 5 by using the speed reduction holes on the speed reduction plate 51, thereby enabling better condensation of water vapor. It has good practicality, and the filter screen 54 can be disassembled and maintained from the outside by bolts.

[0024] like Figure 2 As shown, the feeding plate 53 is inclined inside the cooling box 5, and a heat-conducting rod 52 is installed through the outside of the cooling box 5. This arrangement allows the condensed water to be tilted into the liquid outlet pipe 4 using the feeding plate 53, and the heat-conducting rod 52 can be used to introduce the energy of the cooling water in the recovery box 1 into the cooling box 5 to achieve the purpose of efficient condensation of water vapor.

[0025] like Figure 4As shown, the inside of the recovery tank 1 is equipped with cooling water. The inlet end of the pump 3 is connected to the pump pipe 33 inside the recovery tank 1. The drain pipe 31 is L-shaped. At least six nozzles 321 are symmetrically arranged on the rear surface of the nozzle 32. This arrangement uses the pump 3 to draw the cooling water inside the recovery tank 1, and after drawing, it enters the nozzle 32 through the drain pipe 31. Finally, it is sprayed outward through the nozzles 321 to spray the condenser pipe 21 and condense the water vapor inside.

[0026] The working principle of this utility model is as follows: When using the energy-saving defogging cooling tower water vapor recovery equipment, the inlet pipe 2 is connected to the water vapor outlet of the cooling tower. This connection can be made via pipe docking, which is existing technology and will not be discussed further here. When the water vapor from the cooling tower is discharged, it enters the condenser tube 21 through the inlet pipe 2. After entering, the cooling water inside the recovery tank 1 is drawn out through the extraction pipe 33 by the liquid pump 3, and then enters the spray pipe 32 through the discharge pipe 31. Finally, it is sprayed outward through the nozzle 321 to achieve the cooling effect on the interior of the condenser tube 21. The water vapor is cooled to facilitate subsequent condensation, thereby improving the water vapor recovery efficiency. When the water vapor enters the cooling box 5, it is slowed down by the deceleration plate 51. Since the cooling box 5 is located inside the recovery box 1 and is in contact with the cooling water, the water vapor inside the cooling box 5 can be condensed and recovered. At the same time, the heat conduction rod 52 can be used to transfer the energy of the cooling water to the cooling box 5, achieving better condensation recovery. During recovery, the condensed water is discharged through the discharge plate 53, and the filter screen 54 can filter the impurities in the condensate water, which is practical.

[0027] The liquid pump used in this invention is a known existing electrical device that connects to an external controller and power supply. It can be purchased and used directly on the market. Its structure, circuit, and control principle are all known technologies. The appropriate model is selected according to the actual use. Therefore, the structure, circuit, and control principle of the device will not be described in detail here.

[0028] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principles of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. Structures, devices, and operating methods not specifically described or explained in this utility model are implemented according to conventional methods in the art, unless otherwise specified or limited.
