Description

Technical Field

[0001] This utility model relates to an air purification device, and more particularly to an air purification device for the production of perovskite photovoltaic modules, which is applied in the field of air purification device technology. Background Technology

[0002] Perovskite photovoltaic modules have become a research hotspot and development direction in the field of solar photovoltaics due to their high photoelectric conversion efficiency and low-cost manufacturing process. However, perovskite materials have extremely stringent requirements for the production environment. Impurities such as particulate matter, organic pollutants, water vapor, and corrosive gases in the air can contaminate the perovskite thin film during the module manufacturing process, leading to film defects and thus affecting the photoelectric performance and stability of the module.

[0003] Chinese patent CN119836189A discloses a method, apparatus, and photovoltaic module for treating particulate matter in perovskite photovoltaic modules. This invention can reduce the probability of particulate matter affecting the encapsulation effect in the semi-finished perovskite photovoltaic modules to be tested, thereby improving the encapsulation effect of perovskite photovoltaic modules and thus improving the stability and service life of perovskite photovoltaic modules.

[0004] Traditional filter-type air purifiers can remove some particulate matter, but they are not very effective at purifying small particles, organic pollutants, and water vapor. Utility Model Content

[0005] In view of the above-mentioned prior art, the technical problem to be solved by this utility model is that although traditional filter-type air purification equipment can remove some particulate matter, its purification effect is not good for particles with small diameters, organic pollutants, water vapor, etc.

[0006] To address the aforementioned problems, this utility model provides an air purification device for perovskite photovoltaic module production, comprising a purification device with an air inlet and an air outlet. The purification device includes a particle removal chamber, an organic matter purification chamber, and a water vapor removal chamber. The air inlet is connected to the particle removal chamber, and the air outlet is connected to the water vapor removal chamber. The particle removal chamber, organic matter purification chamber, and water vapor removal chamber are connected by air pipes. Multiple filter screens are fixedly connected at equal intervals within the particle removal chamber, with the mesh density increasing from left to right. The organic matter purification chamber... The wall is fitted with a frame plate filled with activated carbon. Multiple serpentine condenser tubes are evenly spaced inside the water vapor removal chamber, and the condenser tubes are filled with low-temperature condensate. The top of the condenser tubes is clamped at equal intervals, and the clamps are fixedly connected to the top wall of the water vapor removal chamber through the mounting plate. A water collection pan is located directly below the condenser tubes inside the purification equipment. A drain outlet extending outside the purification equipment is opened on the side of the water collection pan. A suction pump is installed on the side of the drain outlet, and the input end of the suction pump is connected to the drain outlet through a delivery pipe. The output end is connected to a sewage recovery tank on one side of the purification equipment through a delivery pipe.

[0007] The air purification equipment described above, by setting up a particle removal chamber, an organic matter purification chamber, and a water vapor removal chamber, can purify the small-sized particles, organic pollutants, and water vapor in the waste generated during the production of perovskite photovoltaic modules.

[0008] As a further improvement of this application, a scraper is provided on the surface of the condenser tube, and the scraper is made of non-absorbent nylon.

[0009] As a further improvement of this application, each of the two adjacent scrapers is connected by a connecting plate. The inner wall of the water vapor removal chamber is rotatably connected to a set of self-rebound rollers and a rotating shaft at the upper and lower ends of the condenser tube, respectively. The surfaces of the self-rebound rollers and the rotating shaft are respectively fitted with a second limiting plate and a first limiting plate corresponding to the connecting plate.

[0010] As a further improvement of this application, a first pull rope is wound around the surface of the self-rebound reel inside the second limiting plate, and the end of the first pull rope away from the self-rebound reel is fixedly connected to the top of the connecting plate located directly below. A second pull rope is wound around the surface of the rotating shaft inside the first limiting plate, and the end of the second pull rope away from the rotating shaft is fixedly connected to the bottom of the connecting plate located directly above.

[0011] As another improvement of this application, a tray is fixedly connected to the side of the purification equipment, a servo motor is fixedly connected to the tray, and the output end of the servo motor is connected to one of the rotating shafts.

[0012] As a further improvement to this application, both rotating shafts are fitted with belt pulleys on their surfaces outside the purification equipment, and the two belt pulleys are connected by a belt.

[0013] As a further improvement to this application, a controller for controlling the servo motor and the suction pump is fixedly connected to the purification equipment.

[0014] In summary, waste generated during the production of perovskite photovoltaic modules enters the particle removal chamber through the air inlet. Within this chamber, the air undergoes multiple layers of filtration to remove airborne particles. The filtered air then enters the organic matter purification chamber via a pipe, where it is further filtered by activated carbon to remove organic pollutants. The purified air then enters the moisture removal chamber through a pipe. Since the condenser tubes are filled with low-temperature condensate, and this condensate heats up over time, a water pump extracts and cools the condensate before re-injecting it into the condenser tubes for continued cooling. This condensate circulation system ensures the condensate remains in a continuous cooling state. When humid air passes through, water vapor condenses on the surface of the condenser tubes, falling into a water collection pan. A controller then activates a suction pump to drain the water from the pan through a delivery pipe, thus dehumidifying the air. Attached Figure Description

[0024] The two embodiments of this application will be described in detail below with reference to the accompanying drawings.

[0025] First implementation method:

[0026] Figures 1-5An air purification device for perovskite photovoltaic module production is shown, comprising a purification device 1 with an air inlet and an air outlet. The purification device 1 includes a particulate removal chamber 2, an organic matter purification chamber 3, and a water vapor removal chamber 4. The air inlet is connected to the particulate removal chamber 2, and the air outlet is connected to the water vapor removal chamber 4. The particulate removal chamber 2, the organic matter purification chamber 3, and the water vapor removal chamber 4 are connected by air pipes. Multiple filter screens 5 are fixedly connected at equal intervals within the particulate removal chamber 2, with the mesh density of the filter screens 5 increasing from left to right. A plate frame is installed on the inner wall of the organic matter purification chamber 3, and the plate frame is filled with activated carbon. 6. Multiple serpentine condenser tubes 7 are equidistantly arranged inside the water vapor removal chamber 4. The condenser tubes 7 are filled with low-temperature condensate. The top of the condenser tubes 7 are clamped with clamps 24 at equal intervals. The clamps 24 are fixedly connected to the top wall of the water vapor removal chamber 4 through the mounting plate 23. A water collection pan 8 is provided inside the purification equipment 1 directly below the condenser tubes 7. A drain outlet 15 extending to the outside of the purification equipment 1 is opened on the side of the water collection pan 8. A suction pump 21 is provided on the side of the drain outlet 15. The input end of the suction pump 21 is connected to the drain outlet 15 through the delivery pipe 22. The output end is connected to the sewage recovery tank on one side of the purification equipment 1 through the delivery pipe 22.

[0027] Working principle: Waste generated during the production of perovskite photovoltaic modules enters the particle removal chamber 2 through the air inlet. Within the particle removal chamber 2, multiple layers of filters 5 remove airborne particles. The filtered air then enters the organic matter purification chamber 3 through an air pipe. The air is further filtered by activated carbon 6 to purify organic pollutants. The purified air then enters the water vapor removal chamber 4 through a pipe. Since the condenser tube 7 is filled with low-temperature condensate, and the condensate temperature rises after a period of use, a water pump extracts and cools the condensate before it is drawn back into the condenser tube 7 for continued cooling. This keeps the condensate in a circulating cooling state. When humid air passes through, water vapor condenses on the surface of the condenser tube 7, falling into the water collection pan 8. The controller then activates the suction pump 21, which discharges the water from the water collection pan 8 through the delivery pipe 22, thus dehumidifying the air.

[0028] By setting up a particle removal chamber 2, an organic matter purification chamber 3, and a water vapor removal chamber 4, the system can purify the small-sized particles, organic pollutants, and water vapor in the waste generated during the production of perovskite photovoltaic modules.

[0029] Second implementation method:

[0030] Figures 4-7The condenser tube 7 is shown to be fitted with a scraper 13, which is made of non-absorbent nylon. Adjacent scrapers 13 are connected by a connecting plate 16. A set of self-rebound rollers 19 and a rotating shaft 14 are rotatably connected to the upper and lower ends of the condenser tube 7, respectively, on the inner wall of the water vapor removal chamber 4. The surfaces of the self-rebound rollers 19 and the rotating shaft 14 are respectively fitted with a second limiting plate 20 and a first limiting plate 17 corresponding to the connecting plate 16. A first pull rope 18 is wound around the surface of the self-rebound roller 19 inside the second limiting plate 20. The end of the first pull rope 18 away from the self-rebound roller 19 is connected to the top of the connecting plate 16 located directly below. The end is fixedly connected, and a second pull rope 25 is wound around the surface of the rotating shaft 14 inside the first limiting plate 17. The end of the second pull rope 25 away from the rotating shaft 14 is fixedly connected to the bottom end of the connecting plate 16 located directly above. A support plate 9 is fixedly connected to the side end of the purification equipment 1. A servo motor 10 is fixedly connected to the support plate 9. The output end of the servo motor 10 is connected to one of the rotating shafts 14. Both rotating shafts 14 are fitted with belt pulleys 11 on their surfaces outside the purification equipment 1. The two belt pulleys 11 are connected to each other by a belt 12. A controller for controlling the servo motor 10 and the suction pump 21 is fixedly connected to the purification equipment 1.

[0031] The working principle is as follows: the servo motor 10 is activated by the controller to drive one of the rotating shafts 14, and the belt pulley 11 and belt 12 drive the two rotating shafts 14 to rotate synchronously, thereby winding up the second pull rope 25 on the surface of the rotating shaft 14, realizing the synchronous downward pulling and moving of multiple scrapers 13. During the movement, the scrapers 13 come into contact with the surface of the condenser tube 7, which can sweep down the water droplets condensed on the surface of the condenser tube 7 and drip them into the water collection tray 8. When the scraper 13 is at the bottom of the condenser tube 7, the servo motor 10 drives the rotating shaft 14 in the opposite direction to lengthen the second pull rope 25. At this time, the first pull rope 18 located above the scraper 13 automatically rebounds and rewinds through the self-rebound winding shaft 19, driving the scraper 13 to move upward. This cycle continues, moving the scraper 13 up and down to continuously clean the water droplets on the surface of the condenser tube 7.

[0032] By setting a circulating up-and-down moving scraper 13 on the surface of the condenser tube 7, the water droplets condensed on the surface of the condenser tube 7 can be cleaned.

[0033] In light of current practical needs, the above-described embodiments adopted in this application are not limited to these. Any changes made within the scope of knowledge possessed by those skilled in the art without departing from the concept of this application still fall within the protection scope of this utility model.
