Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this utility model.

[0024] Implementation

[0025] Please see Figure 1 -4. A lead-acid battery acid vapor treatment device, comprising: a sealed box 1, a connecting pipe 3, an air pump 8 and a spray deacidification tank 12. An air sensor 7 is installed inside the sealed box 1. A vent 4 is opened inside the sealed box 1. The vent 4 is connected to the connecting pipe 3. A solenoid valve 19 is installed at the connection between the connecting pipe 3 and the vent 4. The air pump 8 is fixedly connected inside the sealed box 1.

[0026] The connecting pipe 3 is fixedly connected to the input end of the air pump 8, the output end of the air pump 8 is fixedly connected to the conveying pipe 9, one end of the conveying pipe 9 is fixedly connected to the particle filter 10, the output end of the particle filter 10 is fixedly provided with a limestone filter tank 11, and the output end of the limestone filter tank 11 is provided with a spray deacidification tank 12.

[0027] The conveying pipe 9 is interconnected with the particulate filter 10, the limestone filter tank 11, and the spray deacidification tank 12.

[0028] The technical solution provided in this embodiment is as follows: When the battery is inside the sealed box 1 for charging or other operations, the sealed door 2 is first locked by the electromagnetic lock 6. The partition 5 divides the internal space, making the space utilization rate higher. The air sensor 7 continuously monitors the pH value of the internal space of the sealed box 1. When the pH value in a certain compartment drops rapidly, the electromagnetic valve 19 at the rear of the corresponding compartment opens. At the same time, the air pump 8 and water pump 15 start. The air pump 8 opens the air passage through the connecting pipe 3 to open the electromagnetic valve 19 to draw air and output the internal gas to the internal particulate filter 10. At this time, the particulate filter 10 first filters the particulate matter inside the gas to reduce the filtration pressure behind it. Then the gas passes through... The limestone filter tank 11 first removes acid from the gas by using limestone to reduce its acidity. Then, the gas passes through the spray deacidification tank 12. With the activation of the water pump 15, the sodium hydroxide solution in the water tank 14 is transported to the inside of the connecting ring 122. The connecting ring 122 atomizes the solution through the atomizing nozzle 123, so that the gas inside the delivery tank 121 can fully contact the sodium hydroxide solution, reducing its acidity. After further deacidification, the gas and liquid are discharged into the storage tank 20 at the same time. Due to the higher weight of the liquid, it sinks to the bottom, and the gas is discharged through the output pipe 17. Finally, the gas passes through the activated carbon filter tank 18 for final filtration, removing harmful substances before being discharged.

[0029] Furthermore, the spray deacidification tank 12 includes a conveying tank 121, a connecting ring 122, and an atomizing nozzle 123. The conveying tank 121 is connected to the limestone filter tank 11 through a conveying pipe 9. The inner wall of the connecting ring 122 is provided with an atomizing nozzle 123, which is inserted into the inside of the conveying tank 121. The output end of the atomizing nozzle 123 is located inside the conveying tank 121.

[0030] Specifically, by setting up the acid spraying pipe 12, the acid mist can undergo further acid-base neutralization after being deacidified by the limestone filter tank 11.

[0031] Furthermore, a water tank 14 is provided inside the sealed box 1. A cover plate 16 is inserted into the top of the water tank 14. A water pipe 13 is inserted into the inside of the water tank 14. The end of the water pipe 13 is inserted into the inside of the connecting ring 122. The water pipe 13 is connected to the atomizing nozzle 123 through the connecting ring 122. A water pump 15 is provided on the outer wall of the water pipe 13.

[0032] Specifically, through the arrangement of water tank 14 and water pump 15, after water pump 15 is started, the water inside water tank 14 is output to the inside of connecting ring 122 and output through atomizing nozzle 123, which can effectively bring the solution into contact with acid mist.

[0033] Furthermore, a storage tank 20 is provided inside the sealed box 1. The output end of the spray deacidification tank 12 is connected to the inside of the storage tank 20 through the delivery pipe 9. An output pipe 17 is inserted into the top of the storage tank 20. An activated carbon filter tank 18 is fixedly connected to the outer wall of the sealed box 1. The activated carbon filter tank 18 and the output pipe 17 are interconnected.

[0034] Specifically, the storage tank 20 can store the solution that has reacted with the acid mist, and the output pipe 17 is inserted into its top, allowing the gas to be output separately and then filtered through the activated carbon filter canister 18 for final filtration.

[0035] Furthermore, the sealed box 1 is equipped with a partition 5 inside, and the air sensor 7 is installed on the inner wall of the partition 5.

[0036] Specifically, the partition 5 effectively improves the space utilization inside the sealed box 1, allowing more batteries to be stored inside.

[0037] Furthermore, a sealing door 2 is rotatably connected to the outer wall of the sealing box 1, and an electromagnetic lock 6 is installed inside the sealing box 1.

[0038] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
