[0024] The present invention will now be described in further detail with reference to the accompanying drawings.

[0025] To solve the above-mentioned technical problems, the technical solution provided by this utility model is: a rotary dehumidifier condensation heat recovery energy-saving device, combined with the attached... Figure 1-2 The device includes: a heat collection tank 4 and a heat dissipation tank 5 located on the top and bottom respectively, and a base plate 1 for supporting and installing the heat collection tank 4 and the heat dissipation tank 5. The base plate 1 has a reserved area for installing relevant controllers. Through the controller containing the corresponding control system, the motor 12, water pump, valve and other components in the device, as well as auxiliary sensors and other equipment added later and belonging to the prior art, are associated and controlled. The base plate 1 is connected to a bracket 2 that provides stable support for the heat collection tank 4 and the heat dissipation tank 5, as well as the drive shaft 13, the water supply pipe 6 and the drain pipe 8. The heat collection tank 4 is connected to the air duct 3 on both sides, which is connected to the rotary dehumidifier. The air duct 3 has a flange structure at the end. One end is connected to the exhaust port of the rotary dehumidifier, and the other end is connected to the relevant dry air demand location. On the air duct 3, a fan can be added according to objective needs. The dry and hot gas processed by the rotary dehumidifier passes through the air duct 3 and is discharged. The top and bottom of the heat dissipation tank 5 are respectively connected to a water supply pipe 6 and a drain pipe 8. A water pump 7 is installed on the water supply pipe 6, and a solenoid valve 9 is installed on the drain pipe 8. The water supply pipe 6 and the drain pipe 8 are respectively connected to the relevant water source and hot water and heat demand locations. The heat dissipation tank 5 is equipped with a circulation component that promotes water circulation within the tank to achieve sufficient heating. The circulation component includes a return pipe 10 connected between the water supply pipe 6 and the drain pipe 8. A second water pump 11 is installed on the return pipe 10. After the first water pump 7 and the solenoid valve 9 are turned off, the water from the water supply end can no longer enter the heat dissipation tank 5, and the water discharged from the heat dissipation tank 5 cannot be effectively discharged into the relevant hot water receiving container. Instead, it can only flow back into the heat dissipation tank 5 along the return pipe 10 under the action of the second water pump 11. Through internal and external water circulation, the water in the heat dissipation tank 5 is kept in dynamic flow, thereby increasing the contact with the relevant heat-conducting components and ensuring sufficient heating. Based on the circulating requirement of repeated water heating and the arrangement of pipes, water pump 7 is arranged on the side of water supply pipe 6 away from heat sink 5 on return pipe 10, and solenoid valve 9 is arranged on drain pipe 8 away from heat sink 5 on return pipe 10. Combined with appendix Figure 3-6 A heat transfer assembly is installed between the heat collection tank 4 and the heat dissipation tank 5. The heat transfer assembly includes a hollow support shaft 17 rotatably connected between the heat collection tank 4 and the heat dissipation tank 5. A drive assembly for rotating the support shaft 17 is installed on the base plate 1. The drive assembly includes a transmission shaft 13 rotatably connected above the base plate 1. A motor 12, which drives the transmission shaft 13, is installed on the base plate 1. A main pulley 14 is installed on the top of the transmission shaft 13. Figure 7 A secondary pulley 16 is connected to the support shaft 17, and a transmission belt 15 is installed between the main pulley 14 and the secondary pulley 16. The motor 12 starts and runs continuously, causing the drive shaft 13 to rotate. Then, through the belt drive mechanism consisting of the main pulley 14, the drive belt 15 and the auxiliary pulley 16, the support shaft 17 rotates inside the heat collection tank 4 and the heat dissipation tank 5. Since the heat collection tank 4 is filled with gas and the heat dissipation tank 5 is filled with water, when the support shaft 17 is connected to the two tanks, a sealed bearing or related sealing measures must be used. A temperature-conducting rod 18 is installed inside the support shaft 17. Both ends of the temperature-conducting rod 18 extend into the heat collection tank 4 and the heat dissipation tank 5, respectively, and are connected to a stirring assembly. The stirring assembly includes multiple fan blades 19 evenly distributed and connected to the ends of the temperature-conducting rod 18. The fan blades are the same as the temperature-conducting rod 18 and are made of heat-conducting materials, such as metal materials or polymer materials. These materials can absorb heat from the surrounding environment and raise its temperature. The device can use common and inexpensive materials such as copper and aluminum. The fan blades 19 rotate in the fluid medium, creating a stirring effect, actively seeking the medium and making contact with it, triggering heat transfer, thereby accelerating and more fully heating the cold water in the heat dissipation tank 5 from the hot air in the heat collection tank 4, and reducing heat loss. Combined with appendix Figure 8 The fan blade 19 is provided with multiple filter holes 20, which can actively increase the contact area between the fan blade and hot air or cold water from the structural design stage, improve the heat conduction rate, absorb the heat of the air in the heat collection tank 4 through the heat transfer component, and dissipate the collected heat into the water in the heat dissipation tank 5, thereby realizing the collection of condensation heat of the rotary dehumidifier. The heat collection tank 4, heat dissipation tank 5, support shaft 17, air duct 3, water supply pipe 6, drain pipe 8 and return pipe 10 are all made of heat insulation material to prevent the heat carried by the internal air or water from leaking out and causing heat loss.

[0026] In the specific implementation of this utility model, the gas treated by the rotary dehumidifier is discharged through the air duct 3 connected to the device. Before the device is used to recover the condensation heat of the rotary dehumidifier, the motor 12 has already entered the running state, causing the support shaft 17 to carry the heat-conducting fan blades and maintain moderate rotation in the heat collection tank 4 and the heat dissipation tank 5 respectively. The heat dissipation tank 5 is filled with cold water through the water supply pipe 6. Hot air circulates in the air duct 3. When it passes through the heat collection tank 4, it is blocked by the rotating fan blades in the tank. The hot air comes into full contact with the fan blades, and the fan blades actively capture the heat. The heat is transferred to the fan blades and continues to be transferred to the fan blades in the heat dissipation tank 5 through the heat conduction rod 18. The fan blades in the heat dissipation tank 5 are immersed in cold water and continue to rotate, transferring the heat they carry to the cold water. The cold water is heated and discharged through the drain pipe 8 at the bottom of the tank. After the water flows out of the heat sink 5, it can return to the heat sink 5 through the return pipe 10 with the second water pump 11. At this time, the first water pump 7 on the water supply pipe 6 has already been turned off before the current heat collection process. The water flowing back into the heat dissipation tank 5 absorbs heat as much as possible. After several reasonable cycles, the solenoid valve 9 on the drain pipe 8 is finally opened, and after the water pump 11 stops running, the hot water is discharged into the relevant receiving container, thus completing the waste heat recovery work. In addition, after the rotary dehumidifier stops working, the motor continues to run for a period of time. Since the water temperature in the heat exchange tank 5 is always equal to or lower than the air temperature in the heat collection tank 4, in order to prevent the heat in the heat transfer component from being wasted, the heat transfer process in the heat exchange tank 5 is given a little more time, allowing the water to absorb heat as much as possible and reach a stable relative balance between the two heat transfer components, thereby reducing heat waste.

[0027] The present invention and its embodiments have been described above. This description is not restrictive, and the accompanying drawings are only one embodiment of the present invention; the actual structure is not limited thereto. In conclusion, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the inventive spirit of the present invention, such designs should fall within the protection scope of the present invention.
