Description

Technical Field

[0001] This invention relates to the technical field of dust removal equipment, and more particularly to a dust removal device used in the battery recycling process. Background Technology

[0002] Batteries have a wide range of applications and can provide power for various products. Currently, new energy electric vehicles, which are being vigorously promoted as smokeless transportation tools, mainly use lead-acid batteries to provide power for movement. In the lead-acid battery recycling process, the dust removal and purification device generally adopts a two-layer structure. The upper layer is equipped with filter bags. When smoke and dust pass through the upper layer, the dust is intercepted by the filter bags, and the waste filter bags fall into the lower layer. The gas after dust removal is directly discharged into the atmosphere.

[0003] The current dust removal method has obvious defects. When the gaps in the filter bags are too large, they are damaged, or there is too much dust that covers the surface of the filter bags and cannot be cleaned in time, small dust particles and some dust will penetrate the filter bags and enter the atmosphere directly. At the same time, if the gas temperature is high when the battery is crushed, the entropy value of the overall gas mixture will increase, causing molecular disorder, which is not conducive to dust separation. Furthermore, it cannot neutralize the acidic gas generated during the crushing of lead-acid batteries, resulting in the emission of acidic gas and environmental pollution. Summary of the Invention

[0004] In view of the problems existing in the dust removal devices used in the current battery recycling process, the present invention is proposed.

[0009] The filtration unit includes a filtration component disposed on one side of the reaction assembly, and the bottom of the filtration component is fixedly connected to a fixed bracket.

[0010] As a preferred embodiment of the dust removal device used in the battery recycling process of the present invention, the bottom of the buffer is provided with an upper groove plate, the bottom of the upper groove plate is provided with a lower groove plate, and both the upper groove plate and the lower groove plate are fixedly connected to the conical tank.

[0011] As a preferred embodiment of the dust removal device used in the battery recycling process of the present invention, the conical tank is provided with a filter plate inside, and a curved plate is provided on the top of the filter plate, and the curved plate is fixedly connected to the conical tank.

[0012] As a preferred embodiment of the dust removal device used in the battery recycling process of the present invention, the guiding component includes an L-shaped guide plate 1 disposed inside the conical tank, an L-shaped guide plate 2 disposed inside the conical tank, and a scraper disposed inside the conical tank, wherein the L-shaped guide plate 1 and the L-shaped guide plate 2 are arranged in a coordinated manner at an inclined angle to guide the dust and gas.

[0013] As a preferred embodiment of the dust removal device used in the battery recycling process of the present invention, the recycling component includes a storage section disposed at the bottom of the conical tank, a top plate disposed at the top of the storage section, and a cleaning component disposed on the conical tank.

[0014] As a preferred embodiment of the dust removal device used in the battery recycling process of the present invention, the water curtain assembly includes a water pump mounted on a fixed support and a U-shaped pipe mounted at the output end of the water pump, wherein the input end of the water pump passes through and is connected to the storage unit.

[0015] As a preferred embodiment of the dust removal device used in the battery recycling process of the present invention, the other end of the U-shaped tube is provided with a conveying pipe, and a spray pipe is provided at the top of the conveying pipe.

[0016] As a preferred embodiment of the dust removal device used in the battery recycling process of the present invention, the spray pipe is provided with a movable trough, and two layers of pipes are slidably and rotatably connected inside the movable trough.

[0017] As a preferred embodiment of the dust removal device used in the battery recycling process of the present invention, the outer diameter of the two-layer tube is provided with multiple double-layer nozzles, the inner side of the two-layer tube is rotatably provided with a single-layer tube, and the outer diameter of the single-layer tube is provided with multiple reverse nozzles.

[0019] The beneficial effects of this invention are as follows: During the battery recycling and crushing process, after ash and harmful gases enter the reaction assembly, the impact buffer buffers and guides them, ensuring smooth gas flow. Simultaneously, the water curtain assembly draws ammonia from the recycling assembly and sprays out three layers of water curtain. After the ash and gas impact the water curtain, they come into large-area contact with the ammonia, resulting in a neutralization reaction of the harmful gases, a decrease in temperature, and the adsorption of large heavy metal particles, which then fall into the recycling assembly. The ammonia is filtered and recycled. Subsequently, the ash and gas are guided by the guiding assembly to rotate inside a conical tank, further enhancing the neutralization reaction between the harmful gases and the ammonia. As the amount of ash and gas increases... The first harmful gases are squeezed out and transported to the filter assembly for removal and preliminary filtration. Through multiple stages of treatment, including buffering, spray neutralization, and separation filtration, dust is effectively prevented from directly entering the atmosphere due to excessively large gaps or damage to the filter bags. This avoids situations where dust covers the filter bags and cannot be cleaned. At the same time, ammonia spraying and rotation neutralization reduce the gas temperature, preventing the high temperature from causing an increase in the entropy of the mixed gas and molecular disorder, which is not conducive to dust separation. Furthermore, it neutralizes the acidic gases generated during the crushing of lead-acid batteries, preventing them from being directly discharged and polluting the environment. This improves dust removal efficiency and reduces environmental pollution. Attached Figure Description

Detailed Implementation

[0032] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0033] Example 1, referring to Figures 1-3 The first embodiment of the present invention provides a dust removal device used in the battery recycling process. The device includes: a fixed bracket 100, a reaction dust removal unit 200, and a filter unit 300.

[0034] The reaction dust removal unit 200 includes a reaction component 201 disposed on a fixed support 100, a guide component 202 disposed inside the reaction component 201, a recovery component 203 disposed at the bottom of the guide component 202, and a water curtain component 204 disposed on one side of the recovery component 203, wherein the water curtain component 204 penetrates and is fixedly connected to the reaction component 201.

[0035] The filter unit 300 includes a filter component 301 disposed on one side of the reaction component 201, and the bottom of the filter component 301 is fixedly connected to the fixed bracket 100. When the battery is recycled and crushed, a large amount of ash and electrolyte are generated. At the same time, the electrolyte generates acidic harmful gases such as hydrogen fluoride and phosphoric acid. When dealing with acidic harmful gases such as hydrogen fluoride and phosphoric acid, since the use of ammonia water has lower requirements for the environment and temperature, ammonia water is used to neutralize the acidic gases such as hydrogen fluoride and phosphoric acid. The reaction generates corresponding salts and water. In addition, the salts generated during the reaction will dissolve in the water to form a neutralized solution. The neutralized solution can be further processed, such as separating solid salts through precipitation, filtration and other methods for recycling. The generated water can be recycled or discharged in compliance with standards. Through the neutralization reaction of ammonia water, the emission of acidic gases can be effectively reduced, and the pollution to the environment can be reduced.

[0036] When the dust and soil gas enters the interior of the reaction component 201, if the dust and soil gas content is high, it will directly impact the buffer component 2013 inside the reaction component 201. The buffer component 2013 buffers and guides the large volume of dust and soil gas entering. At the same time, the water curtain component 204 starts to extract ammonia water from inside the recovery component 203 and delivers it to the other end of the water curtain component 204 for spraying. Through the unique spray structure of the water curtain component 204, the sprayed ammonia water forms a three-layer water curtain. The dust and soil gas impacts the water curtain. When the dust and soil gas passes through the water curtain, it comes into direct contact with the ammonia water in the water curtain over a large area. The harmful gas begins to react and neutralize with the ammonia water, and at the same time, it quickly reduces the heat inside the dust and soil gas, causing the internal temperature of the dust and soil gas to drop significantly, ensuring subsequent filtration and separation.

[0037] The water curtain adsorbs large heavy metal particles from the ash and soil gas, causing them to fall to the recovery component 203. The impurities are then trapped at the top by the filtration system in the recovery component 203, and the ammonia water returns to the recovery component 203 for reuse. The ash and soil gas, carrying some ammonia water, is guided by the reaction component 201 to the guiding component 202. Guided by the guiding component 202, the ash and soil gas moves upwards, and under the influence of gravity, the particles inside the ash and soil gas begin to fall downwards, while the harmful gases move upwards. Guided by the reaction component 201 and the guiding component 202, the harmful gases are contained within the conical tank 2011. The reaction component rotates internally, enhancing the reaction and neutralization of harmful gases with ammonia. As more and more dusty gas accumulates, the initially entering harmful gases are forced out and guided by the guide component 202 to the filter component 301. This process removes harmful gases from the dusty gas and performs preliminary filtration of heavy metal particles. Furthermore, the buffer component 2013 and push plate 2015 inside the reaction component 201 can adaptively adjust according to the dusty gas content, ensuring the neutralization reaction of harmful gases within the dusty gas. The dusty gas then enters the filter component 301, is filtered by the filter component 301, and is subsequently discharged.

[0038] During battery recycling and crushing, a large amount of ash and electrolyte are generated. The electrolyte also produces acidic and harmful gases such as hydrogen fluoride and phosphoric acid. Ammonia is used to neutralize these gases because it has lower requirements for environmental conditions and temperature. The reaction produces salts and water, and the salts dissolved in the water form a neutralized solution. This solution can be further processed, such as by precipitation and filtration, to separate solid salts for recycling. The generated water can be recycled or discharged in compliance with standards. The neutralization reaction with ammonia effectively reduces the emission of acidic gases and lowers environmental pollution.

[0039] When the dust and soil gas enters the interior of the reaction component 201, if the dust and soil gas content is high, it will directly impact the buffer component 2013 inside the reaction component 201. The buffer component 2013 buffers and guides the large volume of dust and soil gas entering. At the same time, the water curtain component 204 starts to extract ammonia water from inside the recovery component 203 and delivers it to the other end of the water curtain component 204 for spraying. Through the unique spray structure of the water curtain component 204, the sprayed ammonia water forms a three-layer water curtain. The dust and soil gas impacts the water curtain. When the dust and soil gas passes through the water curtain, it comes into direct contact with the ammonia water in the water curtain over a large area. The harmful gas begins to react and neutralize with the ammonia water, and at the same time, it quickly reduces the heat inside the dust and soil gas, causing the internal temperature of the dust and soil gas to drop significantly, ensuring subsequent filtration and separation.

[0040] The water curtain adsorbs large heavy metal particles from the ash and soil gas, causing them to fall to the recovery component 203. The impurities are then trapped at the top by the filtration system in the recovery component 203, and the ammonia water returns to the recovery component 203 for reuse. The ash and soil gas, carrying some ammonia water, is guided by the reaction component 201 to the guiding component 202. Guided by the guiding component 202, the ash and soil gas moves upwards, and under the influence of gravity, the particles inside the ash and soil gas begin to fall downwards, while the harmful gases move upwards. Guided by the reaction component 201 and the guiding component 202, the harmful gases are contained within the conical tank 2011. The reaction component rotates internally, enhancing the reaction and neutralization of harmful gases with ammonia. As more and more dusty gas accumulates, the initially entering harmful gases are forced out and guided by the guide component 202 to the filter component 301. This process removes harmful gases from the dusty gas and performs preliminary filtration of heavy metal particles. Furthermore, the buffer component 2013 and push plate 2015 inside the reaction component 201 can adaptively adjust according to the dusty gas content, ensuring the neutralization reaction of harmful gases within the dusty gas. The dusty gas then enters the filter component 301, is filtered by the filter component 301, and is subsequently discharged.

[0041] Example 2, refer to Figures 1-8This is the second embodiment of the present invention, which differs from the first embodiment in that: the reaction assembly 201 includes a conical tank 2011 disposed on a fixed support 100, a connecting pipe 2012 disposed on one side of the conical tank 2011, a buffer member 2013 disposed inside the conical tank 2011, a return spring 2014 disposed inside the buffer member 2013, and a push plate 2015 disposed at the other end of the return spring 2014, wherein the push plate 2015 is slidably connected to the buffer member 2013, an upper groove plate 2016 is disposed at the bottom of the buffer member 2013, a lower groove plate 2017 is disposed at the bottom of the upper groove plate 2016, and both the upper groove plate 2016 and the lower groove plate 2017 are fixedly connected to the conical tank 2011, and a filter plate 2018 is disposed inside the conical tank 2011. A curved plate 2019 is provided at the top of the 2018, and the curved plate 2019 is fixedly connected to the conical tank 2011. When the battery is crushed and recycled, the generated harmful gases and ash enter the interior of the conical tank 2011 together. The gas and ash entering the conical tank 2011 directly impact the surface of the push plate 2015, causing the push plate 2015 to squeeze the return spring 2014 and begin to slide into the buffer 2013. This makes the buffer 2013 form a buffer zone to buffer the ash and gas and then guide it out. Thus, the push plate 2015 and the return spring 2014 can cooperate to adaptively adjust the ash and gas entering the conical tank 2011, ensuring effective guidance and buffering even when a large amount of ash and gas enters the conical tank 2011.

[0042] Compared to Embodiment 1, the water curtain assembly 204 further includes a water pump 2041 mounted on a fixed bracket 100, and a U-shaped pipe 2042 mounted at the output end of the water pump 2041. The input end of the water pump 2041 passes through and connects to the storage unit 2031. A delivery pipe 2043 is provided at the other end of the U-shaped pipe 2042, and a spray pipe 2044 is provided at the top of the delivery pipe 2043. A moving groove 2045 is provided inside the spray pipe 2044, and the moving groove 2045 slides and rotates inside. A double-layer pipe 2046 is connected, with multiple double-layer nozzles 2047 installed on the outer diameter of the double-layer pipe 2046. A single-layer pipe 2048 is rotatably installed inside the double-layer pipe 2046, with multiple reverse nozzles 2049 installed on the outer diameter of the single-layer pipe 2048. The dust and gas, guided and buffered by the buffer element 2013, begins to move downwards. Simultaneously, the water pump 2041 starts operating, drawing ammonia water from inside the recovery component 203 and conveying it to the spray pipe 2044 through the U-shaped pipe 2042 and the delivery pipe 2043. Inside the conical tank 2011, during the impact of ammonia water, the second-layer pipe 2046 moves upward within the moving tank 2045, while simultaneously spraying through the double-layer nozzle 2047. The spray from the double-layer nozzle 2047 generates an impact force that causes the pipe to rotate. The first-layer pipe 2048, under the counter-impact of the reverse nozzle 2049, begins to rotate in the opposite direction inside the second-layer pipe 2046. This results in a three-layer reverse rotation of the reverse nozzle 2049 and the double-layer nozzle 2047, forming a large-area water curtain inside the conical tank 2011. When the ash gas passes through the water curtain, it comes into contact with the ammonia water, initiating a neutralization reaction on the acidic substances within the ash gas. Furthermore, as the ash gas passes through the three layers of water curtain, the water curtain also adsorbs heavy metal particles in the gas, causing these particles to fall into the recovery component 203 for unified collection. This also prevents the gas temperature from being too high, which could increase the entropy of the overall mixed gas, leading to molecular disorder and hindering dust separation.

[0043] During use, when the battery is crushed and recycled, the generated harmful gases and ash enter the conical tank 2011. The gas and ash inside the conical tank 2011 directly impact the surface of the push plate 2015, causing the push plate 2015 to press against the return spring 2014 and slide into the buffer 2013. This causes the buffer 2013 to form a buffer zone, buffering the ash and gas before guiding it out. Thus, the push plate 2015 and the return spring 2014 can work together to adaptively adjust the amount of ash and gas entering the conical tank 2011, ensuring effective guidance and buffering even when large quantities of ash and gas enter the conical tank 2011.

[0044] The dust and gas, guided by the buffer 2013, begins to move downwards. Simultaneously, the water pump 2041 starts operating, drawing ammonia water from inside the recovery component 203 and conveying it through the U-shaped pipe 2042 and the delivery pipe 2043 to the spray pipe 2044. During the impact of the ammonia water, the second-layer pipe 2046 moves upwards inside the moving trough 2045, while simultaneously spraying through the double-layer nozzles 2047. The impact force generated by the spray from the double-layer nozzles 2047 causes the second-layer pipe 2048 to rotate. Under the counter-impact of the reverse nozzle 2049, the first-layer pipe 2048 also begins to rotate in the opposite direction inside the second-layer pipe 2046, thus causing the reverse nozzle 2049 to rotate in the opposite direction. 49 and the double-layer nozzle 2047 rotate in three opposite directions, forming a large-area water curtain inside the conical tank 2011. When the dust gas passes through the water curtain, it comes into contact with the ammonia water in the water curtain, and begins to neutralize the acidic substances inside the dust gas. When the dust gas passes through the three layers of water curtain, the water curtain can also adsorb the heavy metal particles in the gas, causing the heavy metal particles inside the gas to fall into the recovery component 203 for unified collection. At the same time, the water curtain can also cool down the temperature inside the dust gas to prevent the gas temperature from being too high, which would increase the entropy of the overall mixed gas, causing molecular disorder and hindering dust separation.

[0045] The remaining structure is the same as that in Example 1.

[0046] Example 3, referring to Figures 1-10This is the third embodiment of the present invention, which differs from the second embodiment in that: the guiding component 202 includes an L-shaped guide plate 1 2021 disposed inside the conical tank 2011, an L-shaped guide plate 2022 disposed inside the conical tank 2011, and a scraper 2023 disposed inside the conical tank 2011. The L-shaped guide plate 1 2021 and the L-shaped guide plate 2022 are arranged at an inclined angle to guide the dust gas. The recovery component 203 includes a storage section 2031 disposed at the bottom of the conical tank 2011, a top plate 2032 disposed at the top of the storage section 2031, and a cleaning component 2033 disposed on the conical tank 2011. The dust gas that has been separated and cooled by the water curtain is transported to the L-shaped guide plate 1 2021 through the lower groove plate 2017 and the filter plate 2018. Guided by the L-shaped guide plate 1 2021, the gas moves upward. Simultaneously, particulate matter in the gas falls downwards for initial impurity separation. Then, the gas moves upwards and enters between the lower trough plate 2017 and the upper trough plate 2016. Due to the arc angle of the lower trough plate 2017 and the upper trough plate 2016, the harmful gas rotates between them. Since the gas also carries some ammonia water when passing through the water curtain, the ammonia water begins to react and neutralize as the harmful gas rotates, removing acidic substances from the gas. As more and more gas enters, the gas that entered first is squeezed out and moves through the upper trough plate 2016. When the gas passes through the tail end of the upper trough plate 2016, it is scraped to intercept a small amount of moisture inside the gas. The gas that has completed the reaction and neutralization begins to move towards the filter assembly 301 through the scraper 2023, thus completing the initial separation of dust and soil gas and the neutralization of harmful gases.

[0047] The filter assembly 301 includes a connecting pipe 3012 disposed at the other end of the conical tank 2011, a bag filter 3011 disposed on the connecting pipe 3012, a baffle 3013 disposed inside the bag filter 3011, a pulse filter section 3014 disposed on the baffle 3013, and a discharge section 3015 disposed at the top of the pulse filter section 3014. The dust gas neutralized by the reaction assembly 201 enters the interior of the bag filter 3011 through the connecting pipe 3012, and is guided by the baffle 3013 to float upward from the bottom of the bag filter 3011. After being filtered by the pulse filter section 3014, it is finally discharged from the discharge section 3015.

[0048] During operation, the ash-soil gas, after water curtain separation and cooling, is conveyed to the L-shaped guide plate 2021 via the lower trough plate 2017 and filter plate 2018. Guided by the L-shaped guide plate 2021, the gas moves upwards, while particulate matter in the gas falls downwards for initial impurity separation. The gas then moves upwards and enters the space between the lower trough plate 2017 and the upper trough plate 2016. Due to the arc angle between the lower trough plate 2017 and the upper trough plate 2016, the harmful gas can rotate between them. As the gas passes through the water curtain, it also carries some ammonia. When the harmful gas rotates, the ammonia begins to react and neutralize, removing acidic substances from the gas. Then, as more and more gas enters, the gas that enters first is squeezed out and moves through the upper channel plate 2016. When the gas passes through the tail end of the upper channel plate 2016, the gas is scraped to intercept a small amount of moisture inside the gas. The gas that has completed the reaction and neutralization begins to move into the filter assembly 301 through the scraper plate 2023, thereby completing the initial separation of dust and soil gas and the neutralization of harmful gases.

[0049] The dust and gas neutralized by the reaction component 201 enters the bag filter 3011 through the connecting pipe 3012. Guided by the baffle 3013, the dust and gas rises from the bottom of the bag filter 3011, is filtered by the pulse filter section 3014, and finally discharged from the discharge section 3015.

[0050] The remaining structure is the same as that in Example 2.
