Description

Technical Field

[0001] This utility model relates to the field of waste heat recovery and utilization technology, and in particular to a rotary dehumidifier heat pipe temperature difference waste heat power generation system. Background Technology

[0002] A rotary dehumidifier is a device that uses a moisture-absorbing rotary wheel for deep dehumidification. It is particularly good at working efficiently in low-temperature and low-humidity environments (it can effectively dehumidify even when the temperature is as low as 1°C and the relative humidity is as low as 1%). It overcomes the shortcomings of traditional refrigeration dehumidifiers, which are ineffective or even fail due to frost formation in low-temperature environments. Therefore, it is widely used in many industrial and special fields with extremely high humidity control requirements.

[0003] However, the humid and hot exhaust gases generated during the operation of rotary dehumidifiers are usually directly discharged, resulting in a large amount of medium- and low-temperature waste heat not being effectively utilized. Traditional waste heat recovery technologies mostly use heat exchangers or heat pump systems, which have problems such as complex structure, high energy consumption, and poor adaptability to low-grade heat energy. Therefore, how to efficiently recover the low-grade waste heat of rotary dehumidifiers and convert it into electrical energy, while simplifying the system structure and reducing energy consumption, has become an urgent technical problem to be solved.

[0017] To facilitate understanding of this invention, a more comprehensive description of the invention will be provided below with reference to specific embodiments. However, this invention can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided to enable a more thorough and complete understanding of the disclosure of this invention.

[0018] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used in this specification is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention.

[0019] Reference Figure 1This embodiment proposes a rotary dehumidifier heat pipe temperature difference waste heat power generation system, which includes a rotary dehumidifier 1, an air duct 2, multiple heat pipes 3, a temperature difference semiconductor generator 4, and an energy storage device.

[0020] Rotary dehumidifier 1 is existing technology. It uses a honeycomb-shaped moisture-absorbing rotor as its core, combined with air handling, regeneration, and auxiliary systems to achieve continuous and efficient dehumidification. The structure of rotary dehumidifier 1 will not be described in detail here. Generally, rotary dehumidifier 1 has a humid and hot exhaust gas outlet (regeneration air exhaust outlet), which is a key interface responsible for discharging high-temperature and high-humidity regeneration exhaust gas. It is connected to the humid and hot exhaust gas outlet through duct 2 to discharge the humid and hot exhaust gas.

[0021] Multiple heat pipes 3 are vertically arranged inside the duct 2, with one end of each heat pipe 3 extending outside the duct 2. In this configuration, the end of the heat pipe 3 inside the duct 2 forms the evaporation end, while the end outside forms the condensation end. The heat pipe 3 acts as a highly efficient "heat transporter," utilizing external heat at the evaporation end to evaporate the working fluid. The vapor carries latent heat to the condensation end, where it releases the latent heat and condenses into a liquid. Finally, capillary force drives the liquid back to the evaporation end. This closed-loop cycle, based on phase change (evaporation / condensation) and capillary reflux, achieves efficient, rapid, and nearly isothermal heat transfer from the heat source (evaporation section) to the cold source (condensation section). To maximize heat utilization, the heat pipe 3 can be positioned near the outlet of the humid waste gas in the duct 2. In this embodiment, combined with... Figure 2 Multiple heat pipes 3 are arranged in two rows inside the air duct 2. The first row of heat pipes 3 is located upstream of the second row of heat pipes 3. Multiple baffles are installed inside the air duct 2 between the two rows of heat pipes 3 and downstream of the heat pipes 3 to increase the heat exchange time between the humid and hot exhaust gas and the heat pipes 3.

[0022] The thermoelectric generator 4 is existing technology. It has a hot end and a cold end. When the temperature difference between the hot end and the cold end exceeds a preset power generation temperature, the thermoelectric generator 4 will start generating electricity. Since the specific structure and power generation principle of the thermoelectric generator 4 are well known to those skilled in the art, a detailed description of the thermoelectric generator 4 is not provided here. The hot end of the thermoelectric generator 4 is connected to the condensation ends of multiple heat pipes 3. Heat dissipation fins are provided at the cold end of the thermoelectric generator 4. During operation, the thermoelectric generator 4 generates current due to the temperature difference.

[0023] The energy storage device includes an inverter 5 and a battery 6. The inverter 5 is electrically connected to a thermoelectric generator 4, and the battery 6 is electrically connected to the inverter 5. The current generated by the thermoelectric generator 4 is converted by the inverter 5 to form stable electrical energy stored in the battery 6, achieving the effect of waste heat recovery. Of course, in one embodiment, the thermoelectric generator 4 can also be directly electrically connected to the electrical equipment using wires, so that the electrical energy generated by the thermoelectric generator 4 can be directly supplied to the electrical equipment.

[0024] In this embodiment, when the dehumidifier 1 is working, the hot and humid exhaust gas enters the duct 2. The heat pipe 3 absorbs the low-grade heat of the hot and humid exhaust gas and transfers it to the hot end of the thermoelectric generator 4 through the heat pipe 3. The thermoelectric generator 4 uses the temperature difference to generate current. The generated current is converted by the inverter 5 to form stable electrical energy stored in the battery 6, thus achieving the effect of waste heat recovery.

[0025] It should be noted that when a component is said to be "installed on" another component, it can be directly on the other component or it may be in a component that is centered on it. When a component is said to be "set on" another component, it can be directly set on the other component or it may also be in a component that is centered on it. When a component is said to be "fixed to" another component, it can be directly fixed to the other component or it may also be in a component that is centered on it.

The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "or / and" as used herein includes any and all combinations of one or more of the associated listed items.

[0027] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0028] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model.
