Description

Technical Field

[0001] The invention relates to the technical field of photovoltaic pyrolysis, in particular to a continuous pyrolysis device for processing photovoltaic laminates. Background Art

[0002] Photovoltaic modules are generally composed of aluminum frames, junction boxes, tempered glass, EVA film crystalline silicon cells and TPT backboards.

[0003] The chain-plate pyrolysis device serves as the basis of this invention. The existing chain-plate pyrolysis device includes a chain plate and an inlet and outlet. The chain plate is located below the inlet. The material transported from the inlet falls on the chain plate by its own weight and undergoes high-temperature pyrolysis in the furnace body. After the pyrolysis is completed, the waste slag is discharged through the outlet. The outlet is on the lower side of the chain plate.

Therefore, the integrity and cleanliness of the glass plates must be ensured, and the glass plates must be collected and stacked.

[0025] Embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to be used to explain the present invention, but should not be understood as limiting the present invention.

[0026] A continuous pyrolysis apparatus for processing photovoltaic laminates according to an embodiment of the present invention will be described below with reference to the accompanying drawings.

[0027] like Figure 1-4As shown, an embodiment of the present invention proposes a continuous pyrolysis device for processing photovoltaic laminates, comprising: a loading conveyor belt 1, a pyrolysis device 3, a decarbonization device 8 and a unloading conveyor belt 9, the loading conveyor belt 1 is arranged in a horizontal direction; the pyrolysis device 3 has a pyrolysis chamber and a feed port, a discharge port and an exhaust port connected to the pyrolysis chamber, the loading conveyor belt 1 is arranged at an upstream position of the pyrolysis device 3, the loading conveyor belt 1 enters the pyrolysis chamber through the feed port of the pyrolysis device 3, a first chain conveyor 6 and a heating device are arranged in the pyrolysis chamber, the first chain conveyor 6 is arranged in a horizontal direction, the first chain conveyor 6 has a first conveyor belt located at the upper part and a first return belt located at the lower part, the upper end surface of the first conveyor belt is flush with the upper end surface of the loading conveyor belt 1, the loading conveyor belt 1 transfers the photovoltaic laminate 5 to the first conveyor belt, and a first collecting bin 11 for collecting pyrolyzed battery cells is arranged below the tail end of the first conveyor belt. The air outlet is used to discharge the pyrolysis gas in the pyrolysis chamber; the decarbonization device 8 has a decarbonization chamber and a feed port and a discharge port connected to the decarbonization chamber. The decarbonization device 8 is arranged at the downstream position of the pyrolysis device 3. The pyrolyzed photovoltaic laminate 5 passes through the discharge port of the pyrolysis device 3 and the feed port of the decarbonization device 8 in turn and enters the decarbonization chamber. A second chain conveyor 14 is arranged in the decarbonization chamber. The second chain conveyor 14 is arranged in a horizontal direction. The second chain conveyor 14 has a second conveyor belt located at the upper part and a second return belt located at the lower part. The upper end face of the second conveyor belt is flush with the upper end face of the first conveyor belt. The first conveyor belt transfers the photovoltaic laminate 5 to the second conveyor belt; the unloading conveyor belt 9 is arranged at the downstream position of the decarbonization device 8. The unloading conveyor belt 9 is arranged in a horizontal direction. The upper end face of the unloading conveyor belt 9 is flush with the upper end face of the second conveyor belt. The decarbonized glass plate passes through the discharge port of the decarbonization device 8 and is transferred by the unloading conveyor belt 9.

[0028] The embodiment of the present invention provides a loading conveyor belt 1, a first chain conveyor 6, a second chain conveyor 14 and a unloading conveyor belt 9, and the upper end surfaces of the loading conveyor belt 1, the first chain conveyor 6, the second chain conveyor 14 and the unloading conveyor belt 9 are all flush, so that the thermal decomposition of the entire photovoltaic panel laminate can be achieved, and the entire glass plate on the photovoltaic panel can be recycled to ensure the integrity and cleanliness of the glass plate.

[0029] The embodiment of the present invention controls the transmission speeds of the loading conveyor belt 1, the first chain conveyor 6, the second chain conveyor 14 and the unloading conveyor belt 9 respectively through the driving device, and the control is stable, continuous pyrolysis can be achieved, and it is simple and reliable.

[0030] Furthermore, the spacing between two adjacent transmission mechanisms in the feeding conveyor belt 1, the first chain conveyor 6, the second chain conveyor 14 and the unloading conveyor belt 9 must ensure that the photovoltaic laminate 5 can be translated and transmitted between the two adjacent transmission mechanisms, and the spacing between the two adjacent transmission mechanisms must be at least smaller than the length of the photovoltaic laminate 5. The chain plate specifications of the first chain conveyor 6 and the second chain conveyor 14 must also ensure the normal transmission of the photovoltaic laminate 5.

[0031] Furthermore, an insulating furnace wall is arranged outside the decarburization chamber to reduce the temperature loss in the decarburization chamber.

[0032] Furthermore, the specifications of the pyrolysis device 3 and the decarbonization device 8 are determined according to the specifications and processing capacity of the photovoltaic panels.

[0033] Furthermore, a second collecting bin 16 is provided in the decarbonization chamber below the tail of the second chain conveyor 14 for collecting products separated from the glass plate.

[0034] In some embodiments, Figure 1 As shown, the heating device is a radiation tube 4, and a plurality of radiation tubes 4 are provided and arranged above the first conveyor belt and between the first conveyor belt and the first return belt, so that the pyrolysis of the photovoltaic laminate 5 can be more complete.

[0035] In some embodiments, the decarburization chamber has an air inlet, a hot gas inlet and an exhaust port, through which the air required for decarburization is introduced into the decarburization chamber, a plurality of hot gas inlets are arranged and arranged at the top of the decarburization chamber, and the heat required for decarburization is provided to the decarburization chamber through the hot gas inlet, and the exhaust port of the decarburization chamber is connected to a gas treatment device. The gas treatment device can purify the waste gas generated by decarburization and then discharge it into the atmosphere to avoid polluting the atmosphere.

[0036] It should be noted that oxygen can also be introduced into the air inlet.

[0037] In some embodiments, Figure 1 As shown, the continuous pyrolysis device for processing photovoltaic laminates also includes a combustion chamber 10, which has an air inlet and an exhaust port. The exhaust port of the pyrolysis device 3 is connected to the air inlet of the combustion chamber 10 through a pipeline, and the exhaust port of the combustion chamber 10 is connected to the hot air inlet of the decarbonization device 8 through a heat transfer pipe 15 to provide the heat required for decarbonization.

[0038] The pyrolysis gas discharged from the pyrolysis device 3 is introduced into the combustion chamber 10 to continue to burn as fuel, and the high-temperature flue gas discharged from the combustion chamber 10 provides heat for the decarbonization chamber, thereby realizing effective utilization of resources.

[0039] It should be noted that although the high-temperature flue gas introduced into the decarbonization chamber will reduce the proportion of oxygen, according to actual operations, only a small amount of oxygen is needed to complete the decarbonization operation, so the impact of introducing high-temperature flue gas on decarbonization is very small.

[0040] Furthermore, a plurality of heat transfer pipes 15 are evenly distributed so that the photovoltaic laminate 5 in the decarbonization chamber is heated evenly.

[0041] In some embodiments, Figure 1 As shown, a first furnace door 2 is provided at the feed inlet of the pyrolysis device 3, a second furnace door 12 is provided at the discharge port of the pyrolysis device 3, a third furnace door 13 is provided at the feed inlet of the decarbonization device 8, a fourth furnace door 17 is provided at the discharge port of the decarbonization device 8, a first gas barrier device 18 is connected to the first furnace door 2, a second gas barrier device 7 is connected between the second furnace door 12 and the third furnace door 13, and the first gas barrier device 18 has the same structure as the second gas barrier device 7.

[0042] By providing a gas barrier device, the pyrolysis gas in the pyrolysis chamber can be prevented from overflowing from the furnace door to the outside and causing pollution to the outside.

[0043] Furthermore, the first gas barrier device 18 and the second gas barrier device 7 spray high-temperature gas at a temperature of 300-500° C. This can ensure the integrity of the glass plate to the greatest extent and prevent the glass plate from breaking due to a sharp change in temperature.

[0044] Furthermore, the first furnace door 2 and the second furnace door 12 are both sealed and connected to ensure the sealing of the pyrolysis chamber.

[0045] In some embodiments, Figure 3 , 4 As shown, the first gas barrier device 18 includes a shell 74 and an injection pipe 71. The shell 74 is connected to the first furnace door 2. The injection pipe 71 is supported on both sides of the shell 74 in the horizontal direction. A plurality of linear nozzles 75 are evenly distributed on the injection pipe 71. The air inlet of the injection pipe 71 is connected to the inert gas source through a pipeline. The linear nozzle 75 injects and blocks at the first furnace door 2 to prevent the pyrolysis gas from diffusing out of the boundary. The shell 74 of the second gas barrier device 7 is connected between the second furnace door 12 and the third furnace door 13.

[0046] Furthermore, the inert gas source is a nitrogen tank, and the jet pipe 71 is connected to the nitrogen tank via an air inlet pipe.

[0047] In some embodiments, Figure 3 , 4As shown, the first gas barrier device 18 has two gas injection pipes 71, which are respectively arranged above and below the first furnace door 2; the second gas barrier device 7 also has two gas injection pipes 71, which are respectively arranged above and below the second furnace door 12. By arranging two gas injection pipes 71 on the furnace door, the pressure value of the nitrogen gas ejected can be guaranteed, and the nitrogen gas ejected can be ejected from the upper and lower directions of the furnace door respectively, so that the ejected nitrogen gas can completely seal the pyrolysis gas in the pyrolysis chamber.

[0048] Furthermore, the linear nozzle 75 of the air injection pipe 71 disposed above the furnace door sprays air downward, and the linear nozzle 75 of the air injection pipe 71 disposed below the furnace door sprays air upward.

[0049] In some embodiments, Figure 3 , 4 As shown, the injection pipe 71 is rotatably connected to the housing 74 to adjust the injection angle of the injection pipe 71. The purpose is to enable the injected nitrogen to completely seal the pyrolysis gas in the pyrolysis chamber.

[0050] Furthermore, the jet pipe 71 is connected to the housing 74 via a bearing, the inner ring of the bearing is connected to the jet pipe 71, and the outer ring of the bearing is connected to the air inlet pipe of the nitrogen tank. A dial 72 is provided at the connection between the housing 74 and the jet pipe 71, and the rotation angle of the jet pipe 71 can be adjusted according to the dial 72, thereby adjusting the spray angle of the linear nozzle 75.

[0051] Furthermore, the gas pressure of the air inlet pipe of the nitrogen tank can be adjusted, which can prevent the pyrolysis gas from overflowing to the outside of the pyrolysis chamber to the greatest extent.

[0052] In some embodiments, Figure 3 , 4 As shown, the bottom of the housing 74 is connected to a height adjustment device 73 to adjust the height of the injection pipe 71. The height of the injection pipe 71 can be adjusted according to actual use conditions so that the injected nitrogen can completely seal the pyrolysis gas in the pyrolysis chamber.

[0053] Furthermore, the height adjustment device 73 can be designed as a telescopic hollow sleeve structure and fixed by a latch. The height adjustment device 73 can also be a hydraulic lifting device.

[0054] In some embodiments, Figure 1 As shown, the pyrolysis chamber is a "convex" shaped structure, and the pyrolysis chamber includes an inlet chamber, an intermediate chamber and an outlet chamber. The intermediate chamber is located between the inlet chamber and the outlet chamber. The height of the inlet chamber is smaller than that of the intermediate chamber, and the height of the outlet chamber is equal to that of the inlet chamber. The heating device is arranged in the intermediate chamber.

[0055] It should be noted that when the glass plate just enters the pyrolysis chamber and after the pyrolysis is completed, the temperature of the glass plate will change sharply and cause it to break. Therefore, the pyrolysis chamber is designed as a "convex" shape structure, which plays a certain preheating role when the photovoltaic panel enters the pyrolysis chamber, and plays a slow cooling effect during the discharge process, effectively avoiding the breakage of the glass plate.

[0056] The heat is concentrated in the middle cavity, which improves the utilization efficiency of the heat. The temperature at the first furnace door 2, the second furnace door 12 and the driving sprocket is relatively low, which is beneficial to improve the sealing effect of the pyrolysis chamber and increase the service life of the equipment.

[0057] It should be noted that the temperatures at the first furnace door 2, the second furnace door 12 and the drive sprocket are relatively low, and a wider range of sealing materials with better sealing properties are available for selection. If the temperature is high, the sealing material will be damaged. Therefore, the temperatures at the first furnace door 2, the second furnace door 12 and the drive sprocket are relatively low, which will be beneficial to improving the sealing effect of the pyrolysis chamber.

[0058] When in use, the loading conveyor belt 1 translates the entire photovoltaic laminate 5 into the pyrolysis chamber, closes the first furnace door 2 and the second furnace door 12, makes the pyrolysis chamber reach a sealed state, and uses the built-in radiation tube 4 of the pyrolysis chamber to pyrolyze the photovoltaic laminate 5. After the pyrolysis is completed, the first furnace door 2 and the second furnace door 12 are opened, and the gas barrier devices on both sides of the pyrolysis device 3 are activated to prevent the pyrolysis gas in the pyrolysis chamber from overflowing after the furnace door is opened. The pyrolyzed photovoltaic laminate 5 is translated into the decarbonization chamber. Since some pyrolysis products are adhered to the glass plate after pyrolysis, decarbonization is required to remove the sticky materials. At the same time, the pyrolyzed battery cells are collected in the first collection bin 11, and the photovoltaic laminate 5 in the loading area is translated into the pyrolysis chamber through the loading conveyor belt 1 for the next pyrolysis, and the pyrolysis operation is completed in a cycle. The decarbonized glass plate is transported to the unloading area by the unloading conveyor belt 9 to complete the stacking collection.
