Description

Technical Field

[0001] This utility model relates to the technical field of photovoltaic panel recycling equipment, specifically to a cooling device for photovoltaic panel recycling. Background Technology

[0002] With the rapid development of the photovoltaic industry, the recycling and processing of waste photovoltaic panels has become a top priority. Photovoltaic panel dismantling equipment lines, with their advanced technology, provide strong support for the resource utilization of waste photovoltaic panels.

[0003] The pyrolysis route decomposes the organic components in photovoltaic panels through high-temperature heating, thereby separating different materials. This process effectively handles composite layer materials in photovoltaic panels that are difficult to separate physically. During pyrolysis, waste photovoltaic panels are fed into a specific pyrolysis furnace and heated in an inert gas environment. As the temperature rises, organic materials such as the backsheet and encapsulating adhesive in the photovoltaic panel gradually decompose into gases and liquids. The gaseous products generated by pyrolysis can be condensed to obtain combustible gases and oily liquids. Inorganic materials such as glass, silicon wafers, and metals retain their original form after pyrolysis, facilitating subsequent separation and recycling. The outstanding advantage of the pyrolysis route is its excellent separation effect, enabling deep separation of complex composite materials in photovoltaic panels and improving the purity of resource recovery. Furthermore, the energy generated during pyrolysis can be self-sufficient or supplied externally, improving energy utilization efficiency. However, this process requires high-temperature resistance and sealing of the equipment, necessitating strict control of heating temperature and time to ensure the safe and stable operation of the pyrolysis process. It is suitable for processing waste photovoltaic panels with complex compositions and high separation purity requirements.

[0004] Existing cooling devices cannot be directly applied to photovoltaic panel recycling, mainly for the following reasons: 1. The products of photovoltaic panel recycling contain paraffin wax, oily liquids, and non-condensable gases. Paraffin wax can easily clog cooling pipes, making regular cleaning difficult. 2. The products of photovoltaic panel recycling are diverse, requiring the separation of multiple products, which makes recycling difficult. Utility Model Content

[0005] This utility model proposes a cooling device for photovoltaic panel recycling, which solves the problems of easy blockage of cooling pipes, difficulty in cleaning, and difficulty in recycling photovoltaic panel products.

[0006] The technical solution of this utility model is as follows: a cooling device for photovoltaic panel recycling, including a box body, a cooling water inlet on the bottom of one side of the box body, and a cooling water outlet on the top of the opposite side, and a cooling component, the cooling component consisting of cooling pipes, a sedimentation chamber, a maintenance chamber, a gas inlet, a gas outlet, an oil drain pipe, a cover seat, a cover, and a Torx screw. The cooling component is submerged in the box body. The cooling pipes are arranged horizontally, with sedimentation chambers connected to the beginning and end of the cooling pipes. At least one maintenance chamber is connected to the middle of the cooling pipe. A gas inlet is connected to the front end of the sedimentation chamber, and a gas outlet is connected to the rear end of the other sedimentation chamber. The gas inlet and gas outlet extend from the side of the box body. The oil drain pipe passes through the bottom of the sedimentation chamber and the maintenance chamber in sequence and extends from the side of the box body. The tops of the sedimentation chamber and the maintenance chamber penetrate the top of the box body. A cover seat is located on the top of the sedimentation chamber and the maintenance chamber. A cover is rotatably connected to one side of the cover seat, and a Torx screw is rotatably connected to the bottom of the other side. The Torx screw is used to lock the cover.

[0007] Preferably, the bottom of the sedimentation tank and the maintenance tank is pointed.

[0008] Preferably, the width of the sedimentation tank and the maintenance tank is at least 800 mm.

[0009] Preferably, the diameter of the cooling pipe is at least 80 mm.

[0010] Preferably, a three-way valve is connected to the end of the oil drain pipe.

[0011] Preferably, the cooling pipe is made of stainless steel.

[0012] Preferably, the gas inlet, gas outlet, cooling water inlet, and cooling water outlet are connected to flanges at their ends.

[0013] Preferably, the length of the box body is not less than 6000mm.

[0014] Preferably, a sealing ring is provided between the cover seat and the cover.

[0015] The principle of this utility model: This utility model addresses the problems of easy clogging, difficult cleaning, and difficult product recycling in cooling devices for photovoltaic panel recycling. The following technical solution is adopted: This utility model is mainly connected after the photovoltaic panel pyrolysis furnace to process the gaseous and liquid products discharged from the furnace. Based on the existing cooling device, a sedimentation chamber is connected to the beginning and end of the cooling pipe. After cooling, the gaseous products form paraffin wax, oily liquid, and non-condensable gas at room temperature. The sedimentation chamber has two main functions: first, it is used to periodically clean the paraffin wax accumulated in the chamber. Even though a wax-reducing tank is connected after the photovoltaic panel pyrolysis furnace, some paraffin wax still accumulates in the cooling device. Through the sedimentation chamber, operators can use tools such as shovels to clean the paraffin wax; the second function of the sedimentation chamber is to collect particulate matter mixed in with the gaseous products, preventing clogging of the cooling pipe. Furthermore... There is also a maintenance chamber in the middle of the cooling pipe, where workers can enter to clean the paraffin wax and other debris adhering to the pipe walls, making maintenance convenient and easy. The working principle of this utility model is as follows: the gaseous products flowing out of the photovoltaic panel pyrolysis furnace enter through the gas inlet, first filling the sedimentation chamber, and then passing evenly through the cooling pipe connected to the sedimentation chamber. Under the flushing of cooling water, the temperature of the cooling pipe decreases, and the gaseous products are cooled, causing the material form to change and separate into paraffin wax, oily liquid, and non-condensable gas at room temperature. The oily liquid falls into the bottom of the sedimentation chamber and maintenance chamber under the action of gravity and is collected and utilized through the oil drain pipe connected to them. The non-condensable gas at room temperature is discharged through the gas outlet connected to the end sedimentation chamber and collected and utilized separately. This utility model can cool and separate the gaseous products discharged from the photovoltaic panel pyrolysis furnace, making full use of various materials, and the separation difficulty is relatively small.

[0016] The beneficial effects of this utility model are as follows: A cooling device for photovoltaic panel recycling has high cooling efficiency, low maintenance difficulty, low manufacturing cost, high product separation quality of photovoltaic panel pyrolysis furnace, high product utilization rate, reduced fuel costs for recycling companies, and environmentally friendly emissions.

[0026] Specifically, the sedimentation tank 202 and the maintenance tank 203 are at least 800mm wide. In this embodiment, the 800mm wide sedimentation tank 202 and maintenance tank 203 facilitate personnel access to the space, making maintenance convenient and reducing the difficulty of operation.

[0027] Specifically, the diameter of the cooling pipe 201 is at least 80 mm. In this embodiment, using a cooling pipe 201 with a diameter of at least 80 mm results in high heat exchange efficiency.

[0028] Specifically, a three-way valve is connected to the end of the oil drain pipe 206.

[0029] Specifically, the cooling pipe 201 is made of stainless steel. In this embodiment, the cooling pipe 201 made of stainless steel is not easily corroded and has a long service life.

[0030] Specifically, such as Figure 1 , Figure 2 As shown, the gas inlet 204, gas outlet 205, cooling water inlet 102, and cooling water outlet 103 are all connected to flanges at their ends. In this embodiment, the flanges facilitate connection to pipelines, reducing installation difficulty.
