Description

Technical Field

[0001] This utility model relates to the field of heat exchange equipment technology, and in particular to a distillation column air cooler with a flow guide. Background Technology

[0002] A distillation column air cooler is a device that cools the internal high-temperature medium by exchanging heat with the outside air. It is widely used in industrial cooling. It exchanges heat between the internal high-temperature medium and the external medium through an internal sealed circulation pipeline and an external air-cooled or water-cooled circulation system, thereby cooling the internal medium.

[0003] In existing distillation column air coolers, the high-temperature medium enters the heat dissipation pipes mostly through the central pipe, and the medium accumulates in the middle or lower part of the distributor. The utilization rate of the outer ring or top heat dissipation pipes is not high, which reduces the overall heat dissipation effect of the heat dissipation pipes and leads to a decrease in cooling efficiency. Therefore, the existing technology still needs to be improved. Utility Model Content

[0004] To address the aforementioned problems, this invention provides a distillation column air cooler with a flow guide that offers high overall cooling efficiency.

[0005] This utility model provides the following solution to the problems mentioned above:

[0006] A distillation column air cooler with a flow guide includes a heat dissipation device and a housing. The heat dissipation device is mounted on the side wall of the housing, passing through it. A spray pipe is positioned above the heat dissipation device and mounted on the side of the housing. Multiple blowers are located at the top of the housing. Several heat dissipation pipes are installed inside the heat dissipation device, passing through multiple heat dissipation plates. Support plates are located at both ends of each heat dissipation pipe. A flow guide is located at one end of the inlet of each heat dissipation pipe, and a fixed frame is mounted on the flow guide. A rotary motor is located in the middle of the fixed frame. A ring of diverting blades is radially arranged on the rotary motor. The diverting blades are inclined elongated structures with one side attached to the surface of the support plate. A distributor is provided at both ends of the heat dissipation device. The support plate has multiple holes that match the diameter of the heat dissipation pipes. The heat dissipation pipes are fixed in the holes. The support plate, the diverter, and the distributor are all sealed together. The outer shell of the rotary motor inside the diverter is waterproof. One side of the diverting blade is attached to the support plate. When the diverting blade rotates, it can evenly distribute the medium accumulated in the middle and lower part to each heat dissipation pipe.

Several heat dissipation pipes 3 are provided inside the heat dissipation device 2. The heat dissipation pipes 3 pass through multiple heat dissipation plates 4. Support plates 5 are provided at both ends of the heat dissipation pipes 3. A flow guide 9 is also provided at one end of the inlet of the heat dissipation pipe 3. A fixed frame 10 is provided on the flow guide 9. A rotary motor 11 is provided in the middle of the fixed frame 10. The rotary motor 11 has a ring of diverting blades 12 arranged radially. The diverting blades 12 are inclined strip structures with one side attached to the surface of the support plate 5. A liquid separator 6 is provided at both ends of the heat dissipation device 2. The support plate 5 has multiple holes that match the diameter of the heat dissipation pipe 3. The heat dissipation pipe 3 is fixed in the holes. The support plate 5, the guide 9 and the liquid separator 6 are all sealed together. The outer shell of the rotary motor 11 inside the guide 9 has a waterproof function. One side of the diverting blade 12 is attached to the support plate 5. When the diverting blade 12 rotates, it can evenly distribute the medium accumulated in the middle and lower part to each heat dissipation pipe 3.

[0023] The spray pipe 8 has a branched structure with three pipes, and the bottom of the spray pipe 8 is also provided with evenly arranged spray nozzles 13. The branched structure of the spray pipe 8 covers a larger area, and the evenly arranged multiple spray nozzles 13 can spray water evenly onto the heat dissipation device 2, so as to fully exchange heat with the internal medium of the heat exchange pipe.

[0025] The following is the method of using this utility model: The high-temperature medium enters from the inlet of the heat dissipation device 2 and accumulates in the middle and lower part of the distributor 6. The high-temperature medium is evenly distributed into each heat dissipation pipe 3 through the guide 9. It exchanges heat with the external medium in the heat dissipation pipe 3 to achieve cooling, and then is discharged from the distributor 6 at the other end. The external cooling medium is divided into two paths: spray water and air duct. The air is blown in from the blower 7 at the top, and the spray water is evenly sprayed on the heat dissipation device 2 through the spray pipe 8. After the air and spray water exchange heat through the heat exchange device 2, the hot air is blown out from the dustproof louver 15 at the bottom, and the spray water is discharged from the outlet of the box 1. The distributor 6 is sealed and installed in the heat dissipation device 2. The distributor 6 will not affect the normal operation of the middle and lower heat dissipation pipe 3 when it is running.

[0026] By installing a flow guide at the inlet of the heat dissipation pipe, the medium that accumulates in the middle and lower part during feeding is evenly distributed to each heat dissipation pipe, which improves the utilization rate of the heat dissipation pipe and enhances the overall cooling effect; the dust prevention measures at the top and bottom maintain the cleanliness of the box; the reasonable distribution of air ducts and spray pipes also improves the cooling efficiency of the heat dissipation device.
