Description

Technical Field

[0001] This utility model relates to the field of recycling, specifically a system for recycling silicon removal agents in photovoltaic wastewater. Background Technology

[0002] The recycling of photovoltaic wastewater is crucial for the sustainable development of the photovoltaic industry, as it can not only reduce water waste but also reduce environmental pollution.

[0003] Chinese Patent No. CN202021941345.4 discloses a recycling system for phosphorus removal agents, comprising a sedimentation device for settling sludge in wastewater, a sludge thickening tank connected to the sedimentation device, an acid washing tank connected to the sludge discharge outlet of the sludge thickening tank, a reaction tank connected to the liquid phase outlet of the acid washing tank, and a sedimentation tank connected to the reaction tank. The discharge outlet of the sedimentation tank is connected to the sedimentation device. The sedimentation device consists of a biological treatment tank and a secondary sedimentation tank. The outlet of the biological treatment tank is connected to the inlet of the secondary sedimentation tank, the outlet of the secondary sedimentation tank is connected to the sludge thickening tank, and the discharge outlet of the biological treatment tank is connected to the sedimentation tank.

[0004] As can be seen from the above, it is possible to clean the inside of the tank and ensure stable gas pressure inside the tank during the reaction to avoid safety accidents such as leakage of dangerous elements. However, this case also has the following shortcomings: photovoltaic factories generate a large amount of wastewater in the silicon wafer cutting, degumming and cleaning processes. This wastewater is characterized by high salt content, high hardness and difficult-to-degrade organic matter. The presence of silicon not only affects water quality but also brings many challenges to subsequent treatment. Traditional silicon removal methods often require a large amount of reagents and increase the labor intensity of personnel, resulting in resource waste and increased costs.

[0005] Therefore, a photovoltaic wastewater silicon removal agent recycling system is proposed to address the above problems. Utility Model Content

[0006] To address the shortcomings of existing technologies, which lead to resource waste and increased costs, this invention proposes a photovoltaic wastewater desiliconization agent recycling system.

[0007] The technical solution adopted by this utility model to solve its technical problem is as follows: The photovoltaic wastewater silicon removal agent recycling system of this utility model includes a main body and a filter collection component; the filter collection component is equipped with a pump, the input end of the pump is fixedly installed with a suction pipe, the output end of the pump is fixedly installed with a discharge pipe, one end of the discharge pipe is fixedly installed with a cover, the bottom of the cover is fixedly installed with a centrifuge, and the inner cavity of the centrifuge is movably installed with a filter plate.

[0008] Preferably, the main body is equipped with a vibrating screen, and an exciter is fixedly installed on the top of the vibrating screen.

[0009] Preferably, a drop pool is fixedly installed at the bottom of the vibrating screen, and a suction pipe is fixedly installed on one side of the drop pool.

[0010] Preferably, a support frame is fixedly installed at the bottom of the centrifuge, a transmission belt is fixedly installed at the top of the support frame, the transmission belt is located directly below the centrifuge, and a vibrating screen is provided on one side of the transmission belt.

[0012] Preferably, a heating wire is fixedly installed on the top of the support frame, and a fan is fixedly installed on the top of the heating wire.

[0013] The advantages of this utility model are:

[0014] This invention, through the structural design of the filter collection component, starts the pump, sucks up wastewater through the suction pipe, and sends it into the centrifuge through the discharge pipe and cover. Centrifugal force separates the silica flocs, which are then collected by the filter plate and fall onto the transmission belt. The vibrating screen also pushes the initially filtered silica flocs onto the transmission belt. During the transmission process, the heating wire on the support frame heats the silica flocs and the fan dissipates the heat, removing moisture and causing them to crystallize. The wastewater treated by the centrifuge flows into the filter for purification and is then sent to the collection chamber, completing the desiliconization and reagent circulation. This achieves the function of circulating filtration, solves the problems of resource waste and increased costs, and improves the adaptability of recycling work. Attached Figure Description

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.

[0023] Please see Figures 1-5 As shown, a photovoltaic wastewater silicon removal agent recycling system includes a main body 1 and a filter collection component 2. The filter collection component 2 is equipped with a pump 22. A suction pipe 21 is fixedly installed at the input end of the pump 22, and a discharge pipe 23 is fixedly installed at the output end of the pump 22. A cover 26 is fixedly installed at one end of the discharge pipe 23, and a centrifuge 24 is fixedly installed at the bottom of the cover 26. A filter plate 25 is movably installed in the inner cavity of the centrifuge 24.

[0024] During operation, the pump 22 drives the suction pipe 21 at the output end to draw in photovoltaic wastewater. Then, the wastewater is transported through the discharge pipe 23 at the input end to the inner cavity of the centrifuge 24 via the cover 26. Under the centrifugal force of the centrifuge 24, the photovoltaic wastewater is separated, and the silicon flocs contained in the wastewater are separated. The silicon flocs are filtered and collected by the filter plate 25, and then fall down through the scraper inside the centrifuge 24.

[0025] Furthermore, the feature is that: the main body 1 is equipped with a vibrating screen 11, and a vibrator 12 is fixedly installed on the top of the vibrating screen 11;

[0026] During operation, photovoltaic wastewater is coagulated with coagulant to adsorb, neutralize charges, and bridge silicon particles in the water to aggregate and form larger flocs. The coagulated photovoltaic wastewater is then fed to the top of vibrating screen 11, driving vibrator 12 to make vibrating screen 11 vibrate. The screen on vibrating screen 11 is used to initially filter the silicon flocs.

[0027] Furthermore, a drop pool 13 is fixedly installed at the bottom of the vibrating screen 11, and a suction pipe 21 is fixedly installed on one side of the drop pool 13.

[0028] During operation, the filtered photovoltaic wastewater falls into the fall tank 13 by gravity, driving the pump 22 to work, and the photovoltaic wastewater in the fall tank 13 can be sucked up through the suction pipe 21.

[0029] Furthermore, a support frame 27 is fixedly installed at the bottom of the centrifuge 24, and a transmission belt 28 is fixedly installed at the top of the support frame 27. The transmission belt 28 is located directly below the centrifuge 24, and a vibrating screen 11 is provided on one side of the transmission belt 28.

[0030] During operation, the silica flocs fall onto the transmission belt 28 via the scraper inside the centrifuge 24. At the same time, the vibrating screen 11 pushes the filtered silica flocs to one side onto the transmission belt 28 while it is working. The silica flocs are conveyed by the transmission belt 28.

[0031] Furthermore, a filter 29 is fixedly installed on one side of the centrifuge 24, and a collection chamber 31 is fixedly installed on the other side of the filter 29;

[0032] During operation, the photovoltaic wastewater filtered by centrifuge 24 is purified by filter 29 to remove harmful substances contained in the photovoltaic wastewater, and then the purified photovoltaic wastewater is transported to the collection chamber 31 for collection.

[0033] Furthermore, a heating wire 32 is fixedly installed on the top of the support frame 27, and a fan 33 is fixedly installed on the top of the heating wire 32;

[0034] During operation, the silica flocs are heated by heating wire 32 while being conveyed by transmission belt 28. The heat is guided by fan 33 to remove the moisture contained in the silica flocs, causing them to condense into crystals for easy collection later.

[0035] Working Principle: First, photovoltaic wastewater is coagulated with a coagulant. Adsorption, charge neutralization, and bridging promote the aggregation of silicon particles in the water, forming larger silicon flocs. Next, the coagulated photovoltaic wastewater is fed onto the top of a vibrating screen 11 equipped with a vibrator 12. The vibrator 12 is activated, causing the screen 11 to vibrate. The screen mesh performs preliminary filtration and separation of the silicon flocs, with some flocs being screened out. The pre-filtered photovoltaic wastewater falls into a drop pool 13 at the bottom of the vibrating screen 11 due to gravity. At this point, the pump 22 in the filtration and collection assembly 2 is activated. The suction pipe 21 at the input end of the pump 22 generates suction, drawing the photovoltaic wastewater from the drop pool 13. The pump 22 then transports the photovoltaic wastewater through the discharge pipe 23 at the output end, via the cover 26, to the inner cavity of a centrifuge 24. Under the powerful centrifugal force of the centrifuge 24, the remaining silicon flocs in the photovoltaic wastewater are further separated and collected by the filter plate 25. Then, the silicon flocs are scraped off by the centrifuge 24 and fall onto the conveyor belt 28 below. At the same time, the vibrating screen 11, during continuous operation, pushes the silicon flocs obtained from the initial filtration to one side, so that they also fall onto the conveyor belt 28. During the process of the silicon flocs being transported by the conveyor belt 28, the heating wire 32 installed on the top of the support frame 27 heats them, and the fan 33 guides and dissipates the heat, thereby removing the moisture contained in the silicon flocs and causing them to condense into crystals that are easy to collect. The photovoltaic wastewater filtered by the centrifuge 24 flows into the filter 29 on one side. The filter 29 performs deep purification of the photovoltaic wastewater, effectively eliminating the harmful substances contained therein. The purified photovoltaic wastewater is finally transported to the collection chamber 31 for collection, completing the entire process of silicon removal from photovoltaic wastewater and recycling of reagents. In this process, the various components cooperate with each other, from the pretreatment of photovoltaic wastewater, the separation and collection of silicon flocs to the purification and recycling of wastewater.

[0036] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
