Description

Technical Field

[0001] This utility model relates to the field of cooling tower technology, specifically a high-efficiency and energy-saving cooling tower. Background Technology

[0002] A cooling tower is a heat exchange device whose main function is to dissipate waste heat generated in industrial or refrigeration processes into the atmosphere through water evaporation, thereby cooling the water for system recycling. Industrial production (such as power plants, oil refineries, and chemical plants) or large air conditioning systems (such as commercial buildings and data centers) generate a large amount of waste heat, which is usually transferred to cooling water.

[0003] In the prior art, Chinese Patent Application No. CN201910547601.7 discloses a novel cooling tower, including a cooling tower body. A water inlet pipe is connected to the left side of the cooling tower body. One end of the water inlet pipe, located within the inner cavity of the cooling tower body, is connected to a water drain. Both sides of the water drain are fixedly connected to the inner cavity of the cooling tower body. A nozzle is connected to the bottom of the water drain. A transmission water pipe is connected to the top of the water inlet pipe. The water inlet pipe transmits water to the water drain, and then the nozzle sprays it onto the first packing material for cooling. The water in the water inlet pipe is discharged through the transmission water pipe, thereby driving the water turbine blades to rotate. The water turbine blades drive the cooling fan fins to rotate, thereby cooling. The fan body and the second packing material cooperate.

[0004] Based on the above information, it can be seen that existing cooling towers generally achieve cooling by evaporating heat through contact between water and air. However, in actual use, a large amount of water mist is generated during water evaporation. If the water mist is not collected, it will be discharged with the airflow of the fan, resulting in a waste of water resources. Utility Model Content

[0005] The purpose of this invention is to provide a high-efficiency and energy-saving cooling tower to solve the problem of water waste mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a high-efficiency and energy-saving cooling tower, comprising a tower shell installed on the ground, an inspection ladder fixedly installed on the left outer surface of the tower shell, a main fan fixedly installed on the upper surface of the tower shell, and air inlet screens fixedly installed on the left and right sides of the tower shell. Inside the tower shell, from top to bottom, spray pipes, evaporation packing, and a water collection tank are fixedly installed respectively. After being cooled, external air passes through a water collection assembly at the upper end of the tower shell and is discharged from the main fan. Aluminum alloy heat spreaders are fixedly installed at equal intervals inside the water collection tank, and a temperature sensor communicating with the main fan is fixedly installed on the inner wall of the water collection tank.

[0007] Preferably, the water collection assembly includes a water collection plate fixedly installed at the top of the inner shell of the tower body. The water collection plates are evenly distributed at equal intervals, and the cross-section of the water collection plate has a wavy structure.

[0008] Preferably, the water collection plate is internally fixedly installed with heat exchange pipes that are evenly distributed at equal intervals, and the heat exchange pipes are connected to an auxiliary fan that is fixedly installed on the upper surface of the tower shell.

[0009] Preferably, the heat exchange pipe is connected to the diversion pipe via an electrically controlled valve, and the bottom end of the diversion pipe corresponds to the position of the air inlet screen.

[0010] Preferably, the spray pipe is connected to the water inlet pipe, and the water collection tank is connected to the water return pipe.

[0011] Preferably, the evaporation packing comprises three parts: a support plate, a baffle plate, and a sponge pad. The baffle plate is fixedly installed between the upper and lower support plates in a bent structure, and the sponge pad is fixedly installed on the upper surface of the upper support plate.

[0012] Preferably, the sponge pad has through holes distributed in a matrix pattern inside.

[0013] Compared with the prior art, the beneficial effects of this utility model are: this high-efficiency and energy-saving cooling tower adopts a novel structural design, the specific details of which are as follows: 1. The hot water that needs to be cooled is sprayed out through the spray pipe and reaches the position of the evaporation packing. At the same time, the main fan drives the air flow, so that the outside air enters the device through the air inlet and comes into contact with the hot water. At this time, the hot water evaporates and absorbs heat to achieve the purpose of cooling. The heat is carried out by the main fan. When the evaporated water vapor comes into contact with the water collection plate, the water vapor is separated by the wave-shaped structure of the water collection plate, so as to achieve the purpose of water recycling and avoid water resources being discharged and wasted. Furthermore, a heat exchange pipe is fixedly installed inside the water collection plate. During the operation of the device, an auxiliary fan is turned on, which drives the air to circulate in the heat exchange pipe to cool the water collection plate. This causes the hot water vapor to condense into water droplets when it comes into contact with the water collection plate, thus achieving a better recovery effect. Furthermore, a diversion pipe is installed below the heat exchange pipe. By controlling the valve, the airflow driven by the auxiliary fan can be sprayed out from the diversion pipe to clean the air inlet screen.

[0014] 2. The evaporation packing consists of three parts: a support plate, a baffle plate, and a sponge pad. The sprayed water first falls onto the sponge pad, which slows down the water flow. Then, the bent baffle plate increases the water flow distance. The two work together to increase the contact time between water and air, thereby achieving a better cooling effect.

[0015] 3. A temperature sensor is installed inside the water tank to monitor the water temperature after cooling in real time. When the temperature is lower than the set temperature, the power of the main fan can be reduced accordingly to achieve energy saving. Attached Figure Description

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Example 1: See Figures 1-2 and Figure 6To achieve the purpose of recovering cooling water, this embodiment provides the following technical solution, specifically: a tower shell 1 installed on the ground, a maintenance ladder 2 fixedly installed on the left outer surface of the tower shell 1, a main fan 3 fixedly installed on the upper surface of the tower shell 1, and air inlet nets 4 fixedly installed on the left and right sides of the tower shell 1. Inside the tower shell 1, from top to bottom, spray pipes 6, evaporation packing 9, and a water collection tank 5 are fixedly installed respectively. After being cooled, external air passes through the water collection assembly at the upper end of the tower shell 1 and is discharged from the main fan 3. The water collection assembly includes a water collection plate 10 fixedly installed at the top of the tower shell 1. The water collection plates 10 are evenly distributed at equal intervals and have a wavy cross-section. The spray pipes 6 are connected to the water inlet pipe 7, and the water collection tank 5 is connected to the water return pipe 8. Aluminum alloy heat spreaders 14 are fixedly installed at equal intervals inside the water collection tank 5, and a temperature sensor 15 communicating with the main fan 3 is fixedly installed on the inner wall of the water collection tank 5.

[0020] When using the device, the waste heat generated in the factory first enters the spray pipe 6 through the water inlet pipe 7 and is sprayed out evenly. At the same time, the main fan 3 is turned on, and the main fan 3 drives the air flow, so that the outside air enters the tower shell 1 through the air inlet net 4. Then, the hot water and air come into contact with each other at the evaporation packing 9 and evaporate and absorb heat. The generated hot air is discharged through the main fan 3 (when discharged, it comes into contact with the water collection plate 10, which collects water to avoid water discharge and waste). The cooled water droplets fall into the water collection tank 5 for collection. The temperature sensor 15 inside the water collection tank 5 detects the water temperature in real time. When the temperature is lower than the set temperature, the main fan 3 motor is controlled by wireless signal to reduce the power of the main fan 3 to achieve the purpose of energy saving.

[0021] Example 2: See Figure 3 In order to improve the heat exchange effect, this embodiment provides the following technical solution, which specifically discloses that: the evaporation packing 9 includes three parts: a support plate 901, a baffle plate 902 and a sponge pad 903. The baffle plate 902 is fixedly installed between the upper and lower support plates 901 in a bent structure, and the sponge pad 903 is fixedly installed on the upper surface of the upper support plate 901. The sponge pad 903 has through holes 904 distributed in a matrix inside.

[0022] When hot water is sprayed, it first contacts the uppermost sponge pad 903 of the evaporation packing 9, which slows down the water flow. Then the water flows to the baffle plate 902, where the bent structure of the baffle plate 902 increases the flow distance of the water. The combination of the two increases the contact time with the air, achieving a better cooling effect.

[0023] Example 3: See Figures 4-5In order to improve the recycling effect, this embodiment provides the following technical solution, which specifically discloses that: heat exchange pipes 11 with equal spacing are fixedly installed inside the water collection plate 10, and the heat exchange pipes 11 are connected to the auxiliary fan 12 fixedly installed on the upper surface of the tower shell 1. The heat exchange pipes 11 are connected to the diversion pipe 13 through the electrically controlled valve, and the bottom end of the diversion pipe 13 corresponds to the position of the air inlet net 4.

[0024] During the operation of the device, the auxiliary fan 12 on the upper surface of the tower shell 1 is turned on. The auxiliary fan 12 drives the air to flow, so that the air flows in the heat exchange pipe 11. The heat exchange pipe 11 cools the water collection plate 10, so that the hot air condenses when it comes into contact with the plate, achieving a better water collection effect. The valve connecting the diversion pipe 13 and the heat exchange pipe 11 is opened periodically, so that the air in the heat exchange pipe 11 is discharged from the diversion pipe 13, achieving the purpose of blowing and cleaning the air inlet screen 4.
