[0004] The prior art, Chinese patent with publication number CN215781568U, discloses a cooling structure at the top of a centrifugal spray drying tower, which can absorb internal heat through the cooling zone and then discharge the gas through the blower zone. However, in actual use, the blower zone can only dissipate the cooled gas into the air, making it difficult to form effective utilization.

[0013] The technical effects and advantages of this utility model are as follows:

[0014] 1. This utility model uses an air pump to draw heat from the tower body into a cooling device, which then rapidly cools the hot air, converting it into cold air that is discharged into a three-way pipe. When the internal temperature is low, the electric control valve is closed, and the cold air enters the mosquito coil through the L-shaped connecting pipe. The rapid circulation of the cold air within the mosquito coil quickly dissipates the heat in the annular cavity, thus achieving the first stage of heat dissipation.

[0015] 2. This utility model transmits an electrical signal through a temperature sensor to start the water pump and open the electrically controlled valve. The cold air in the three-way pipe enters the cooling box through the cold air pipe to cool the water flowing in the inlet pipe. Then, the water is diverted by the annular diverter plate, causing multiple atomizing nozzles to spray water mist. Through the evaporation of water vapor, heat is absorbed, which drives the surface of the tower to cool down rapidly. It can also cool the surrounding area of ​​the tower simultaneously, achieving a second heat dissipation effect. It effectively utilizes the cold air flow generated by the cooling device, resulting in a good cooling effect. Attached Figure Description

However, those skilled in the art should understand that the detailed description given here with reference to the accompanying drawings is for better explanation. The structure of the present invention may exceed the limited embodiments described herein. Some equivalent alternatives or common means will not be described in detail here, but they still fall within the protection scope of this application.

[0023] Figures 1-5 This is the preferred embodiment of the present invention, which is described below in conjunction with the appendix. Figures 1-5 The present invention will be further described below.

[0024] Specifically, a centrifugal spray drying tower cooling structure includes a tower body 1 and a cooling device 2. It should be noted that, in this embodiment, the specific working principle of the tower body 1 and the cooling device 2 can refer to the technical content used in the cooling structure at the top of a centrifugal spray drying tower disclosed in Chinese Patent Publication No. CN215781568U, which will not be elaborated here. A heat-insulating base 3 is provided at the top of the tower body 1, and the cooling device 2 is located on top of the heat-insulating base 3. The air inlet of the cooling device 2 is connected to the inside of the tower body 1, and a three-way pipe 6 is provided at the air outlet of the cooling device 2. One end of the three-way pipe 6 is provided with a first cooling component, which includes a mosquito coil 8. An annular cavity is formed inside the tower body 1. The mosquito coil 8 is located inside the annular cavity. One end of the mosquito coil 8 is connected to an L-shaped connecting pipe 7, and the other end of the L-shaped connecting pipe 7 is connected to one end of a three-way pipe 6. The other end of the mosquito coil 8 is provided with an exhaust pipe 9, which extends to the outside of the tower body 1. The other end of the three-way pipe 6 is provided with a second cooling component, which includes a cold air pipe 11. One end of the cold air pipe 11 is connected to the three-way pipe 6, and the other end of the cold air pipe 11 is connected to a cooling box 12. A control unit is provided on the cold air pipe 11. The inner walls of the cooling box 12 are provided with mounting holes, and a water inlet pipe 16 is provided in the mounting holes. The cooling box 12 is used to cool the water inlet pipe 16. An atomizing unit is provided at the end of the water inlet pipe 16.

[0025] The control unit includes an electric control valve 18 and a temperature sensor 19. The electric control valve 18 is installed on the cooling pipe 11, and the temperature sensor 19 is installed in the annular cavity. The electric control valve 18 and the temperature sensor 19 are electrically connected. The temperature sensor 19 can sense the temperature in the annular cavity, so that when the temperature reaches the set threshold, a second cooling effect can be achieved. Specifically, the electric control valve 18 is a high-temperature valve to prevent it from malfunctioning in a high-temperature environment. Both the electric control valve 18 and the temperature sensor 19 are controlled by a PLC controller.

[0026] The atomizing unit includes an annular flow divider plate 14. Multiple mounting plates 13 are fixedly installed on the top of the tower body 1. The annular flow divider plate 14 is fixedly installed on the top of the multiple mounting plates 13. A flow divider cavity is provided inside the annular flow divider plate 14. The top end of the water inlet pipe 16 extends into the flow divider cavity. Multiple atomizing nozzles 15 are provided on the inner wall of the annular flow divider plate 14. Specifically, the multiple atomizing nozzles 15 are all controlled by a PLC controller. The multiple atomizing nozzles 15 are all connected to the flow divider cavity. Through the setting of multiple atomizing nozzles 15, the water in the water inlet pipe 16 can be atomized, so that it can evaporate rapidly in a high-temperature environment, taking away the heat from the surface of the tower body 1 and the air near the tower body 1, and achieving a cooling effect.

[0027] The atomizing unit also includes a water pump 17. Specifically, the water pump 17 is controlled by a PLC controller. The water pump 17 is installed on the water inlet pipe 16 and is electrically connected to a temperature sensor 19. The water pump 17 is controlled by the temperature sensor 19 so that when the temperature sensor 19 reaches a set threshold, the water pump 17 is started, driving the cooling water in the water inlet pipe 16 to flow into the annular diverter plate 14.

[0028] The top of the heat insulation base 3 has a connection hole, and an air inlet pipe 4 is fixedly installed in the connection hole. The bottom end of the air inlet pipe 4 extends into the tower body 1, and the other end of the air inlet pipe 4 is connected to the cooling device 2. An air pump 5 is installed on the air inlet pipe 4. Specifically, the air pump 5 is controlled by a PLC controller. Through the installation of the air inlet pipe 4 and the air pump 5, the heat inside the tower body 1 can be drawn into the cooling device 2 for cooling.

[0029] An exhaust pump 10 is installed on the exhaust pipe 9. Specifically, the exhaust pump 10 is controlled by a PLC controller. By setting the exhaust pump 10, the airflow inside the mosquito coil 8 can be quickly discharged, thereby improving the cooling effect.

[0030] The mosquito coil coil 8 is a cooling coil. By setting up the cooling coil, the internal cold air can be circulated, which can quickly drive the external heat out, resulting in a better cooling effect.

[0031] The working principle and usage process of this utility model are as follows: During use, the air pump 5 draws heat from the tower body 1 into the cooling device 2, which rapidly cools the hot air and converts it into cold air, which is then discharged into the three-way pipe 6. When the internal temperature is low, the electric control valve 18 is closed. At this time, the cold air enters the mosquito coil 8 through the L-shaped connecting pipe 7. The cold air circulates rapidly inside the mosquito coil 8, which drives the heat in the annular cavity to dissipate quickly, thus achieving the first level of heat dissipation.

[0032] When the internal temperature reaches the set threshold of the temperature sensor 19, an electrical signal is transmitted through the temperature sensor 19 to start the water pump 17 and open the electric control valve 18. The cold air in the three-way pipe 6 enters the cooling box 12 through the cold air pipe 11 to cool the water flowing in the water inlet pipe 16. Then, the water is diverted through the annular diverter plate 14, causing multiple atomizing nozzles 15 to spray water mist. Through the heat absorption of water vapor evaporation, the surface of the tower body 1 is rapidly cooled down, and the area around the tower body 1 can be cooled simultaneously, achieving a second heat dissipation effect. The cold air flow generated by the cooling device 2 is effectively utilized, resulting in a good cooling effect.

[0033] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model in any other way. Any person skilled in the art may make changes or modifications to the disclosed technical content to create equivalent embodiments. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of this utility model without departing from its technical solution shall still fall within the protection scope of this utility model.
