Description

Technical Field

[0001] This utility model relates to the field of chemical equipment technology, and in particular to a cooling tower for resin reaction. Background Technology

[0002] During resin production, the resin reaction releases a large amount of heat. If it is not cooled in time, it can lead to uncontrolled reaction, reduced product quality, and even safety accidents.

[0003] A search of existing technologies revealed a Chinese patent for "A Cooling Tower for a Resin Reactor," application number "202220070466.9." This patent primarily includes a water tank, tower body, vortex tube, drain pipe, inlet pipe, high-pressure pump, suction pipe, connecting pipe, rotary pipe, rotary joint, water distribution plate, multiple sets of spray nozzles, drive assembly, and air intake assembly. While this patent improves the uniformity of water distribution and replaces traditional straight-pipe cooling methods, resulting in a more compact and smaller device, it also enhances the device's applicability. However, when an air inlet pipe and exhaust fan blades are installed on the side of the tower to cool the vortex tubes, the airflow is greater on the side closer to the inlet pipe, resulting in better cooling of the vortex tubes, while the airflow is smaller on the side farther from the inlet pipe, resulting in poorer cooling of the vortex tubes. This uneven airflow inside the tower may reduce the overall cooling efficiency. Furthermore, when the vortex tubes are cylindrical and cooled by spraying through nozzles, the upper vortex tubes can obstruct the direct flow of cooling water to the lower vortex tubes, making it difficult for the bottom vortex tubes to have uniform and direct contact with the cooling water. Cooling can only rely on the dripping of cooling water from above, and after flowing through the upper vortex tubes, some of the cooling water may increase in temperature after heat exchange, leading to poor cooling of the bottom vortex tubes and potentially reducing the overall cooling efficiency. Therefore, this invention provides a cooling tower for resin reactions to solve the problems mentioned in the background art. Utility Model Content

The fixing strips are attached to the outside of the filter screen.

A fan 8 is fixedly connected to the top of the tower body 1.

[0025] The resin reaction liquid to be cooled enters the heat exchange tube 2 through the inlet pipe 3, flows and exchanges heat inside the heat exchange tube 2, and then exits through the outlet pipe 4. While the reaction liquid flows inside the heat exchange tube 2, the air inlet 5 guides cold air to enter the tower body 1 evenly, ensuring uniform airflow. The fan 8 enhances the airflow inside the tower body 1 through its suction effect, thereby improving the cooling effect on the heat exchange tube 2. Furthermore, designing the heat exchange tube 2 as a tower-shaped structure allows each surface of the heat exchange tube 2 to better contact the cooling water overflowing from the overflow plate 13, avoiding the problem of uneven cooling water distribution at the bottom of the traditional cylindrical heat exchange tube 2, improving cooling uniformity, and ensuring that the resin reaction liquid inside the heat exchange tube 2 can be cooled quickly and evenly.

Multiple overflow ports 14 are symmetrically arranged at equal intervals on the side of the overflow plate 13 near the top. The overflow plate 13 has a circular array structure.

[0027] Cooling water is transported through water pipe 9 to the inside of connecting plate 12 and overflow plate 13, and then evenly distributed to the surface of heat exchange tube 2 through overflow port 14 to form a uniform water distribution effect and enhance the cooling effect.

[0028] A water collection assembly is provided at the bottom of the tower body 1 and below the heat exchange tube 2. The water collection assembly includes a collection plate 10 fixedly connected to the bottom of the tower body 1 and a drain pipe 11 fixedly connected to the bottom of the collection plate 10. The collection plate 10 has a conical structure and collects the water generated during the cooling process. The drain pipe 11 is used to discharge the water from the tower body 1 or to recycle it.

[0029] A filter screen 6 is fitted on the outside of the tower body 1, covering one side of the air inlet 5, to prevent external impurities from entering the tower body 1 through the air inlet 5. The filter screen 6 is detachably installed on the tower body 1 via a connecting assembly, which includes four connecting plates 15, two bolts 16, and four fixing strips 7. Each pair of fixing strips 7 is symmetrically fixed between the connecting plates 15, and each pair of adjacent connecting plates 15 is connected by bolts 16.

[0030] Working principle: The resin reaction liquid to be cooled enters the heat exchange tube 2 through the inlet pipe 3, flows and exchanges heat inside the heat exchange tube 2, and is then discharged through the outlet pipe 4. While the reaction liquid flows inside the heat exchange tube 2, the air inlet 5 guides cold air to enter the tower body 1 evenly, ensuring uniform airflow. The fan 8 enhances the airflow inside the tower body 1 through its suction effect, thereby improving the cooling effect on the heat exchange tube 2. Furthermore, designing the heat exchange tube 2 as a tower-shaped structure allows each surface of the heat exchange tube 2 to better contact the cooling water overflowing from the overflow plate 13, avoiding the problem of uneven cooling water distribution at the bottom of the traditional cylindrical heat exchange tube 2, improving cooling uniformity, and ensuring that the resin reaction liquid inside the heat exchange tube 2 can be cooled quickly and evenly.
