They contain toxic substances such as lead, which will cause environmental pollution. Photovoltaic panels also contain some recyclable materials.

[0023] In the following description, specific details such as specific system structures, technologies, etc. are provided for the purpose of illustration rather than limitation, so as to provide a thorough understanding of the embodiments of the present invention. However, it should be clear to those skilled in the art that the present invention may be implemented in other embodiments without these specific details. In other cases, detailed descriptions of well-known systems, devices, circuits, and methods are omitted to prevent unnecessary details from obstructing the description of the present invention.

[0024] Figure 1 : is an application scenario diagram of the photovoltaic panel pyrolysis recovery method provided by an embodiment of the present invention. Figure 1 As shown, in some embodiments, the photovoltaic panel pyrolysis recovery method provided in the embodiment of the present invention can be applied to but not limited to this application scenario. In this embodiment of the invention, the photovoltaic panel pyrolysis recovery system includes: a disassembly robot 11, a pyrolysis furnace 12, and a control device 13. The control device 13 is connected to the disassembly robot 11 and the pyrolysis furnace 12.

[0025] Among them, the dismantling robot 11 is provided with a camera device. When the photovoltaic panel to be recycled is placed in the area detected by the camera device, the dismantling robot 11 collects relevant information of the photovoltaic panel, then dismantles its peripheral components, and sends the obtained core components to the pyrolysis furnace 12, and then the pyrolysis furnace 12 performs heat treatment on the core components, so that the EVA film therein is softened and decomposed, and the back plate, the complete glass plate and the complete battery cell are separated, and finally the battery cell is put into the corresponding processing equipment to decompose the battery cell into silver, copper, silicon, aluminum and other metals. The control device 13 can be a computer, an industrial computer, a single-chip microcomputer, an MCU, etc., which is not limited here.

[0026] Figure 2 It is a flow chart for implementing the photovoltaic panel pyrolysis recovery method provided in an embodiment of the present invention. Figure 3 is a schematic diagram of the structure of a photovoltaic panel. Figure 2 and Figure 3 As shown, in some embodiments, the photovoltaic panel pyrolysis recovery method is applied to Figure 1 The control device 13 shown in FIG. 1 comprises:

[0027] S210, instructing the disassembly robot to disassemble the peripheral components of the photovoltaic panel to be recycled to obtain the core components of the photovoltaic panel to be recycled; wherein the core components include a back plate, battery cells, and a glass plate; EVA films are provided between the back plate and the battery cells, and between the battery cells and the glass plate.

[0028] In an embodiment of the present invention, the peripheral components include an aluminum frame, a junction box, a tin-coated solder strip, a cable, etc., which are not limited here. The disassembly robot determines the disassembly position and disassembly process of the photovoltaic components by taking images of the photovoltaic components to be recycled, and then completes the disassembly process of the peripheral components. After the disassembly is completed, the image of the core component is taken to confirm that the core component is not damaged during the disassembly process. The disassembly robot then delivers the disassembled core components to the pyrolysis furnace through a robotic arm or a conveyor belt. The backplane can be a TPT solar backplane, a TPE solar backplane, a BBF solar backplane, an APE solar backplane, an EVA solar backplane, etc., which are not limited here.

[0029] S220, heat-treating the core component in the pyrolysis furnace at a preset temperature, and detecting the content information of the target gas in the pyrolysis furnace in real time during the heat treatment process.

[0030] In the prior art, photovoltaic panel heat treatment usually involves placing the photovoltaic panel at a certain temperature for a certain period of time to decompose the EVA film therein. The main cost of photovoltaic panel heat treatment technology lies in the heating energy consumption during the heat treatment process. When the pyrolysis temperature is determined, the heating energy consumption is mainly affected by the heating time.

[0031] However, in the prior art, the heating time can be determined by laboratory measurement, but the laboratory measurement method is relatively cumbersome and can only measure a limited number of types of photovoltaic panels. The photovoltaic panels recycled during the recycling process are likely to be produced by different manufacturers, and the heating time required for their decomposition process must be different. Therefore, the heating time measured in the experiment is used to heat various types of photovoltaic panels, which is bound to cause the heating time to be too long or too short, thereby resulting in incomplete decomposition of the EVA film or excessive energy consumption due to too long heating time.

[0032] Usually, when performing heat treatment on photovoltaic panels, it is necessary to ensure that the EVA film is completely decomposed so that the decomposed glass plates and battery cells do not contain impurities. Therefore, the prior art usually sets a heating time that is greater than the decomposition time of the EVA film. Although it can ensure the complete decomposition of the EVA film, too long a heating time will increase the energy consumption during the heat treatment process, especially when performing batch heat treatment on photovoltaic panels, which will generate a large amount of additional energy consumption.

[0033] When heated, EVA film decomposes into olefins such as carbon dioxide, acetic acid, and ethylene, as well as straight-chain alkanes such as methane and ethane. Therefore, the decomposition state of the EVA film can be determined by detecting the gas content of the gas decomposed by the EVA film in the pyrolysis furnace, so as to accurately control the duration of the heat treatment process. Among them, the target gas can be carbon dioxide gas, acetic acid gas, ethylene gas, etc., which are not limited here. The content information of the target gas can be the concentration of the target gas, the concentration change rate of the target gas, etc., which are not limited here.

[0034] Among them, a target gas detection device is provided in the pyrolysis furnace. The target gas detection device can be a sensor provided with a gas-sensitive material of the target gas, such as a carbon dioxide sensor with lanthanum oxide material, an acetic acid sensor with barium stannate nanotubes, etc. When measuring the content information of the target gas, it is necessary to first detect the ambient temperature of the sensor, and then find the gas sensitivity of the sensor at the current ambient temperature, and then collect the electrical parameters of the sensor, and calculate the current target gas concentration and concentration change rate based on the electrical parameters and gas sensitivity of the sensor. An infrared temperature sensor is provided in the pyrolysis furnace, which can monitor the temperature of the photovoltaic panel.

[0035] S230, when the content information of the target gas in the pyrolysis furnace meets the preset conditions, the heat treatment is terminated to obtain recycled glass plates and battery cells.

[0036] In an embodiment of the present invention, by detecting the content information of the target gas in the pyrolysis furnace, the decomposition of the EVA film during the heat treatment process can be accurately grasped, thereby accurately controlling the heat treatment time of the photovoltaic panel and effectively reducing the recycling cost.

[0037] In some embodiments, the target gas content information includes the concentration change rate of the target gas. Accordingly, S230 may include: when the concentration change rate of the target gas in the pyrolysis furnace decreases to a preset change rate threshold, ending the heat treatment.

[0038] In an embodiment of the present invention, after the temperature of the photovoltaic panel in the pyrolysis furnace is heated to a preset temperature, the concentration change rate of the target gas is monitored. As the EVA film continues to decompose, the amount of gas decomposed per unit time will continue to decrease. Therefore, the concentration change of the target gas first increases to a maximum value and then gradually decreases. When it decreases to a preset change rate threshold, it is considered that the EVA film has completed the decomposition process and the heat treatment is ended.

[0039] In some embodiments, the target gas content information includes the concentration change rate of the target gas and the concentration of the target gas. Accordingly, S230 may include: obtaining the initial EVA content information of the photovoltaic panel to be recycled and the volume of the pyrolysis furnace; calculating the real-time content of the target gas in the pyrolysis furnace according to the volume of the pyrolysis furnace and the concentration of the target gas; determining the maximum generation of the target gas according to the initial EVA content information; when the concentration change rate of the target gas in the pyrolysis furnace decreases to a preset change rate threshold, and the difference between the real-time content of the target gas in the pyrolysis furnace and the maximum generation is less than the preset difference, the heat treatment is terminated.

[0040] The above-mentioned method of detecting the concentration change rate of the target gas only meets the situation where only a single preset temperature is set. When multiple preset temperatures are set, that is, the photovoltaic panels in the pyrolysis furnace are gradually heated and decomposed according to each preset temperature from small to large. When the temperature is raised to each preset temperature, the temperature needs to be maintained for a period of time. Therefore, at each preset temperature, the concentration change rate of the target gas will have a process of first increasing and then decreasing. A single concentration change rate is not sufficient to judge the pyrolysis situation. Therefore, in an embodiment of the present invention, before processing the photovoltaic module to be recycled, its structural information is first obtained to determine the initial EVA content information of the photovoltaic panel, thereby calculating the maximum generation amount of the target gas when the EVA is completely decomposed. When the real-time content of the target gas is close to the maximum generation amount, it is approximately considered that the EVA film is completely decomposed.

[0041] The structural information includes the photovoltaic panel area, EVA film thickness, etc., which are not limited here. The initial EVA content information includes the initial EVA mass and the proportion of vinyl acetate in the EVA film.

[0042] In some embodiments, the preset temperature includes a preset softening temperature and a preset decomposition temperature. Accordingly, S220 may include: heating the core component to a preset softening temperature in the pyrolysis furnace; after a preset time, instructing a manipulator provided in the pyrolysis furnace to remove the back plate; heating the core component to a preset decomposition temperature in the pyrolysis furnace, and detecting the content information of the target gas in the pyrolysis furnace in real time during the heat treatment process.

[0043] Accordingly, Figure 1 A manipulator is provided in the pyrolysis furnace of the photovoltaic panel pyrolysis recovery system shown in FIG.

[0044] In an embodiment of the present invention, the preset softening temperature is lower than the preset decomposition temperature. Since the backplane is prone to produce fluorine-containing waste gas in a high temperature environment, which will increase the treatment cost of the decomposition waste gas, the EVA film can be softened at a lower temperature first, and then the backplane can be directly mechanically removed, and then the core components after the backplane is removed can be decomposed at a higher temperature.

[0045] Among them, when disassembling the backplane, since the EVA film is only softened but not decomposed, there must be some EVA film stuck on the backplane. Therefore, it is necessary to set a weighing device on the manipulator to determine the measured mass of the removed backplane, and determine the actual mass of the backplane based on the structural information of the photovoltaic panel before recycling. The mass of the sticky EVA film can be obtained by subtracting the actual mass of the backplane from the measured mass. Finally, this part of the EVA film is removed from the initial EVA content information, thereby avoiding inaccurate monitoring of the decomposition of the EVA film caused by the removal of the backplane.

[0046] One of the keys to heat treatment is to ensure uniform heating of photovoltaic panels. With the continuous development of technology, the cells in photovoltaic panels are getting thinner and thinner. During the heat treatment process, if the heating is uneven, it is easy to cause the cells with the most recycling value to break.

[0047] In some embodiments, during the execution of S220, the method further includes: detecting the real-time temperature of each location point on the photovoltaic panel to be recycled; and determining the heating power adjustment amount of the pyrolysis furnace according to the real-time temperature of each location point on the photovoltaic panel to be recycled.

[0048] In an embodiment of the present invention, the real-time temperature of each point on the photovoltaic panel to be recycled can be monitored in real time by an infrared temperature sensor to adjust the heating power of each heater in the pyrolysis furnace, thereby ensuring uniform heating of the photovoltaic panel and synchronous temperature rise of each point on the photovoltaic panel.

[0049] In some embodiments, before adjusting the heating power of the pyrolysis furnace according to the real-time temperature of each position point on the photovoltaic panel to be recycled, the method further includes: obtaining the heater type of the pyrolysis furnace and the current heating power of the pyrolysis furnace; according to the heater type of the pyrolysis furnace, selecting a heat prediction model corresponding to the heater type of the pyrolysis furnace; wherein the heat prediction model is used to calculate the predicted value of the heat applied by the pyrolysis furnace to each position point on the photovoltaic panel to be recycled under each heating power; the current heating power of the pyrolysis furnace is input into the heat prediction model to obtain the current predicted value of the heat applied by the pyrolysis furnace to each position point on the photovoltaic panel to be recycled;

[0050] Correspondingly, the heating power adjustment amount of the pyrolysis furnace is determined according to the real-time temperature of each position point on the photovoltaic panel to be recycled, including: determining the heating power adjustment amount of the pyrolysis furnace according to the real-time temperature of each position point on the photovoltaic panel to be recycled and the current heat prediction value of each position point.

[0051] The method of adjusting the heating power only by real-time temperature monitoring by infrared temperature sensors lags behind the monitoring, that is, when the adjustment is made, the temperature imbalance has already occurred. Therefore, the lag will bring certain hidden dangers and easily cause the battery cell to break.

[0052] In an embodiment of the present invention, the type of heater may include a resistive heater, an electromagnetic heater, etc., which are not limited here. Different types of heaters have different spatial temperature field distributions during heating, so it is necessary to establish the relationship between the spatial temperature distribution and the heating power of each heater during heating, which is the above-mentioned prediction model. After the prediction model is established, the current heating state of the photovoltaic panel is reflected by the real-time temperature, and then the temperature change at the next moment is predicted by the current heat prediction value (that is, the distribution of heat loaded on the photovoltaic panel). Finally, the adjustment strategy of the heater is determined in combination with the current heating state of the photovoltaic panel and the temperature change at the next moment, so as to ensure that the photovoltaic panel is heated evenly. The present invention predicts the heat generated by the heater at the next moment, thereby realizing the advance adjustment of the heating power, effectively ensuring that the photovoltaic panel is heated evenly and avoiding the rupture of the battery cell.

[0053] In summary, the beneficial effects of the present invention are specifically as follows:

[0054] By detecting the content information of the target gas in the pyrolysis furnace, the decomposition of the EVA film during the heat treatment process can be accurately grasped, thereby precisely controlling the heat treatment time of the photovoltaic panel and effectively reducing the recycling cost.
