Description

Technical Field

[0001] This utility model relates to the field of solar drying technology, and in particular to a solar PVT-assisted graphene electric heating drying device. Background Technology

[0002] Dryers are devices used in industrial production and laboratories to remove moisture from materials. Their core principle is to vaporize the moisture by heating, ultimately obtaining dry solid materials that meet the requirements. Moisture usually refers to water, but it also includes other volatile liquid components.

[0003] Currently, existing solar dryers use traditional solar collectors as a single heat source, and electric auxiliary heating mostly uses resistance wires. However, the equipment cannot operate continuously on cloudy or rainy days. Furthermore, the resistance wire heating used for electric auxiliary heating has high energy consumption and poor temperature control accuracy, which seriously affects the efficiency of the work. To address these issues, we propose a solar PVT-assisted graphene electric heating drying device. Utility Model Content

[0004] The purpose of this invention is to provide a solar PVT-assisted graphene electric heating drying device, which solves the problem that the equipment cannot work continuously on cloudy or rainy days, and that the electric auxiliary heating uses resistance wire heating, which has high energy consumption and poor temperature control accuracy, and will seriously affect the efficiency of the work.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A solar-powered PVT-assisted graphene electric heating drying device includes a main frame, a drying chamber on the outer surface of the main frame, a solar-powered PVT system on the outer surface of the main frame, a dehumidification and ventilation device inside the drying chamber, a hot air exchange component inside the drying chamber, a PVT water-gas heat exchange component inside the drying chamber, a graphene temperature control system fixedly connected to the outer surface of the drying chamber, and a graphene electric heating film fixedly connected to the bottom of the drying chamber.

[0007] In a preferred embodiment of the solar PVT-assisted graphene electric heating drying device of this utility model, a primary stabilizing frame is fixedly connected to the outer surface of the main frame, a secondary stabilizing frame is fixedly connected to the outer surface of the main frame, an mounting block is fixedly connected to the outer surface of the main frame, an mounting frame is provided on the outer surface of the primary stabilizing frame, and the outer surface of the drying chamber is snapped into the outer surface of the mounting frame.

[0008] In a preferred embodiment of the solar PVT-assisted graphene electric heating drying device of this utility model, the outer surface of the dehumidification and ventilation device is provided with an exhaust component, and the interior of the hot air exchange component is provided with a hot air exchange channel.

[0009] As a preferred embodiment of the solar PVT-assisted graphene electric heating drying device of this utility model, the PVT water source gas heat exchange component includes an auxiliary frame and a pipe, an auxiliary fan is fixedly connected to the outer surface of the auxiliary frame, and a connecting device is fixedly connected to the outer surface of the drying box.

[0010] In a preferred embodiment of the solar PVT-assisted graphene electric heating drying device of this utility model, the solar PVT system includes a PVT mixing component, a force-bearing frame is fixedly connected to the outer surface of the PVT mixing component, and a heat exchanger is fixedly connected to the outer surface of the force-bearing frame.

[0011] In a preferred embodiment of the solar PVT-assisted graphene electric heating drying device of this utility model, a temperature and humidity sensor is fixedly connected to the outer surface of the drying box, and a system controller is provided on the outer surface of the main frame.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] This solar-powered PVT-assisted graphene electric heating drying device utilizes a solar PVT system, which can generate both electricity and hot water, combined with a graphene electric heating film for dual heating. Even without sunlight, it can continuously dry materials using electricity, ensuring stable operation. This effectively solves the problem of continuous operation during cloudy or rainy days. The graphene electric heating film provides rapid heating in three seconds with low energy consumption. Combined with temperature and humidity sensors and a graphene temperature control system, the temperature error is limited to ±1 degree Celsius, preventing materials from burning or drying unevenly. This technology effectively solves the problems of high energy consumption and poor temperature control accuracy associated with resistance wire heating used in electric auxiliary heating. By directly heating the air using a solar PVT system, electricity consumption can be effectively reduced. Furthermore, the graphene electric heating film only assists in heating on cloudy days, saving more than 30% of electricity compared to traditional resistance wire heating, resulting in lower overall energy consumption. The hot air exchange component, combined with the PVT water-gas heat exchange component, allows for more uniform hot air circulation. The graphene electric heating film emits far-infrared rays to deeply heat the materials, and the dehumidification and ventilation device enables rapid dehumidification, resulting in better drying effects.

[0025] In this embodiment: the PVT hybrid component 201 is bolted to the support frame 202, while the heat exchanger 203 is connected by a flange. The entire system is installed at a 30° angle to achieve optimal lighting. The integrated design simultaneously achieves photoelectric and photothermal conversion, ensuring stable output even at a working temperature of 60°C. The modular design facilitates the replacement and maintenance of individual components. The graphene electric heating film 8 is adhered to the bottom of the chamber with high-temperature adhesive, and its thickness is only 0.5 mm. The hot air exchange component 7 has a built-in spiral hot air exchange channel 10 with adjustable wind speed. The dehumidification and ventilation device 6 is equipped with a variable frequency fan and uses a quick-release interface with the exhaust component 4. The copper pipe 13 of the water-gas heat exchange component 9 adopts a corrugated pipe design and utilizes a graphene electric heating film 8, which can heat up in three seconds, reducing energy consumption by 35%. The spiral air duct ensures a heat distribution uniformity of 95%. At the same time, the variable frequency dehumidification system can automatically adjust the power according to the humidity.

Through PID control, the temperature fluctuation is controlled within ±0.5 of the set temperature. The intelligent system can memorize ten sets of drying curves and supports remote monitoring via mobile phone, which can effectively improve the efficiency of equipment use.

[0028] The working principle of this utility model is as follows: In use, the PVT hybrid component 201 in the solar PVT system 2 first collects solar thermal and photovoltaic energy simultaneously, and the generated hot water heats the air through the heat exchanger 203. At this time, the hot air is sent into the drying chamber 3 through the pipe 13 and auxiliary fan 12 of the PVT water source gas heat exchange component 9. When it is cloudy or the temperature is insufficient, the graphene electric heating film 8 will accurately supplement the heat under the control of the graphene temperature control system 15. The heat is evenly distributed through the hot air exchange component 7 and the hot air exchange channel 10. At the same time, the temperature and humidity sensor 16 will monitor and feed back the data to the system controller 14 in real time. Finally, the moisture is discharged by the dehumidification and ventilation device 6 and the exhaust component 4, realizing a highly efficient and energy-saving drying process.
