Description

Technical Field

[0001] This utility model belongs to the field of air precoolers, specifically relating to a fermentation air precooler for cooling towers. Background Technology

[0002] A cooling tower air precooler is a device used to improve the efficiency of a cooling tower. It lowers the temperature of the air entering the cooling tower by precooling the outside air, thereby improving cooling efficiency, saving energy, and reducing operating costs.

[0003] The internal space of existing cooling tower air precoolers is usually continuous. A single heat exchanger is not very effective in circulating the heat of the coolant in a large precooler, resulting in poor cooling effect. Moreover, the heat exchange effect of the coolant alone is relatively limited. If the heat exchange effect is to be improved, the volume of the precooler needs to be increased, which leads to drawbacks in the use of the precooler.

[0004] Therefore, in order to address the problem that existing cooling tower precoolers are not effective in cooling fermentation air, a new fermentation air precooler for cooling towers has been developed. By adding an outer heat dissipation fin structure and a dual heat exchange structure to the precooler, the cooling effect and efficiency of the cooling tower precooler in cooling fermentation air can be effectively improved.

Detailed Implementation

[0023] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0024] Please see Figures 1-5 This utility model provides an embodiment: a fermentation air precooler for cooling towers, including a precooling tank 10 and an auxiliary heat exchanger 2, and also including an external frame 3, heat dissipation fins 5, baffles 8 and heat exchange tubes 9. The outer wall of the precooling tank 10 is fixed with several sets of heat dissipation fins 5 distributed at equal intervals. The inner wall of the precooling tank 10 is fixed with three sets of baffles 8 distributed at equal intervals. The inner walls of the three sets of baffles 8 are fixed with several sets of heat exchange tubes 9 distributed at equal intervals around the inner walls of the baffles 8. The outer wall of the precooling tank 10 has two sets of first interfaces 11 that are symmetrically distributed on the left and right sides. One end of an output pipe 15 and an input pipe 16 that are symmetrically distributed on the front and back are fixed in the first interface 11. The other ends of the output pipe 15 and the input pipe 16 are respectively installed on the output end and the input end of the auxiliary heat exchanger 2. The outer wall of the precooling tank 10 is provided with an external frame 3. The outer wall of the external frame 3 has several sets of dustproof grooves 12 distributed at equal intervals. The left and right ends of the external frame 3 have second interfaces 13 that are symmetrically distributed on the left and right sides.

[0025] The heat exchange space inside the precooling tank 10 can be divided into two parts by three sets of partitions 8. The auxiliary heat exchangers 2 on the left and right sides of the precooling tank 10 are responsible for one heat exchange space respectively, so that the coolant in the precooling tank 10 can perform dual heat exchange and precooling on the fermentation hot air in the heat exchange tube 9. The heat dissipation fins 5 can assist the coolant in the precooling tank 10 to perform additional heat dissipation, thereby improving the effect of the precooling tank 10 in precooling the fermentation hot air.

[0026] Please see Figures 3-4In this embodiment, front and rear connecting covers 4 are fixed to the front and rear ends of the outer frame 3. Connecting grooves 14 are opened through the front and rear ends of the front and rear connecting covers 4. The connecting grooves 14 are fixed to the left and right edges of the outer wall of the precooling tank 10. In use, the front and rear connecting covers 4 can support and fix the front and rear ends of the outer frame 3 so that the outer frame 3 covers the outside of the precooling tank 10. One end of the connector 1 is fixed to the front and rear ends of the precooling tank 10, and the other end of the connector 1 is fixed to the connecting flange 7. In use, the connecting flange 7 can facilitate the user to connect to the fermentation gas delivery pipeline. The heat dissipation fins 5 and the precooling tank 10 are both located inside the outer frame 3. The front and rear ends of the heat exchange tube 9 are on the same plane as the surface of the partition plate 8 located on the inner wall of the front and rear sides of the precooling tank 10. In use, several sets of heat exchange tubes 9 can evenly distribute the fermentation gas in the precooling tank 10 for precooling treatment.

[0027] Please see Figures 3-5 In this embodiment, two sets of baffles 6 are provided between the precooling tank 10 and the auxiliary heat exchanger 2. The two sets of baffles 6 have a first through hole 17 and a second through hole 18 extending through their left and right ends. The two sets of first through holes 17 and second through holes 18 are symmetrically distributed around the center. During use, the baffles 6 prevent the heat from the outer wall of the auxiliary heat exchanger 2 from affecting the normal heat dissipation of the precooling tank 10. The inner wall of the first through hole 17 is in contact with the outer wall of the output pipe 15, and the inner wall of the second through hole 18 is in contact with the outer wall of the input pipe 16. During use, the first through hole 17 and the second through hole 18... The two through holes 18 can be used to position and install the output pipe 15 and the input pipe 16 so that the baffle 6 can be installed on the output pipe 15 and the input pipe 16. The two sets of input pipes 16 and output pipes 15, which are symmetrically distributed on the left and right sides, are connected to the two sets of heat exchange spaces in the precooling tank 10, which are divided by three sets of partitions 8. The other ends of the input pipes 16 and output pipes 15 pass through the second interface 13. In use, the three sets of partitions 8 can divide the heat exchange space in the precooling tank 10 into two spaces, front and rear, so that the two sets of auxiliary heat exchangers 2 can perform cooling circulation on the two sets of heat exchange spaces.

[0028] Before use, connect the connecting pipes to the front and rear sides of the precooling tank 10 via the connecting flange 7;

[0029] When precooling the fermentation air, the fermentation air enters the precooling tank 10 through the connector 1 on the left side of the precooling tank 10 and is evenly distributed on the inner wall of the precooling tank 10 along several sets of heat exchange tubes 9. Then, the cooling liquid in the precooling tank 10 is used to exchange heat and cool the fermentation air in the heat exchange tubes 9.

[0030] Next, the heat exchange space inside the precooling tank 10 can be divided into two parts, front and back, by three sets of partitions 8. The auxiliary heat exchangers 2 on the left and right sides of the precooling tank 10 perform dual heat exchange circulation treatment on the coolant in the two sets of heat exchange spaces to ensure the cooling efficiency and effect of the coolant in the precooling tank 10.

[0031] Then, the heat dissipation fins 5, which are evenly distributed on the outer wall of the precooling tank 10, can assist the coolant in the precooling tank 10 to perform additional heat dissipation, thereby improving the effect of the precooling tank 10 in precooling the fermentation hot air.

[0032] Through the above steps, the heat exchange space inside the precooling tank 10 can be divided into two parts, front and back, by three sets of partitions 8. The auxiliary heat exchangers 2 on the left and right sides of the precooling tank 10 are responsible for one heat exchange space respectively, so that the coolant in the precooling tank 10 can perform dual heat exchange and precooling on the fermentation hot air in the heat exchange tube 9. The heat dissipation fins 5 can assist the coolant in the precooling tank 10 to perform additional heat dissipation, thereby improving the effect of the precooling tank 10 in precooling the fermentation hot air and solving the problem that the existing precoolers used in cooling towers are not effective when used to cool fermentation air.

However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention.
