Description

Technical Field

[0001] This utility model belongs to the field of lithium battery raw material treatment waste gas recovery technology, specifically relating to a lithium battery raw material treatment waste gas recovery device. Background Technology

[0002] Pre-lithiation high-capacity lithium manganese oxide precursor is a specially treated precursor for lithium manganese oxide cathode materials. Specifically, it involves adding an appropriate amount of lithium source to the lithium manganese oxide precursor and subjecting it to certain heat or chemical treatments to ensure the lithium source is uniformly distributed within the precursor, converting it into active lithium during subsequent battery manufacturing. This pre-lithiation treatment can improve the initial capacity of the lithium manganese oxide cathode material, reduce capacity decay, and also improve the battery's rate performance and cycle stability. It is of great significance for improving the performance and application range of lithium-ion batteries.

[0003] The preparation of pre-lithiated high-capacity lithium manganese oxide typically involves high-temperature solid-state sintering or element doping techniques to improve the material's capacity and stability. This process may generate dust (such as manganese oxide particles) and small amounts of volatile organic compounds, and may also release acidic gases (such as hydrogen fluoride) or volatile organic solvents.

[0004] The lithium manganese oxide treatment process generates various waste gases and dust particles. Traditional waste gas recovery equipment can only treat the waste gases in a single way, which can easily lead to waste gas residues that still cause harm to the environment and human health. Therefore, we propose a waste gas recovery equipment for lithium battery raw material treatment. Utility Model Content

A liquid guide pipe 404 is fixedly connected to the surface of the liquid outlet end of the booster water pump 402, and the liquid guide pipe 404 is connected to the multiple spray pipes 405. The exhaust gas is sucked in by the dust removal mechanism 3, and the dust in the exhaust gas is filtered under the action of the dust removal mechanism 3. Then the exhaust gas enters the interior of the neutralization mechanism 2. At this time, the spraying mechanism 4 will spray an alkaline solution to neutralize the acidic gas in the exhaust gas. Then the neutralization mechanism 2 will filter the exhaust gas, thereby reducing the residue in the exhaust gas and improving the environmental protection effect of the equipment.

[0027] Specifically, a collection hopper 5 is fixedly connected to the surface of the water storage tank 1 and below the neutralization cylinder 202. A guide hopper 6 is fixedly connected to one side of the surface of the collection hopper 5 and extends to the outside of the water storage tank 1.

[0028] In a specific embodiment of this utility model, the neutralized liquid falls into the inside of the collecting hopper 5, and the liquid inside the collecting hopper 5 is discharged through the guide hopper 6.

[0029] Specifically, an overflow pipe 7 and a drain valve 8 are fixedly connected to the surface of the water storage tank 1. The overflow pipe 7 is located above the drain valve 8 and is connected to the drain valve 8.

[0030] In a specific embodiment of this utility model, the drain valve 8 facilitates the discharge of liquid inside the water storage tank 1, and the overflow pipe 7 can discharge excess liquid inside the water storage tank 1.

[0031] Specifically, a clamping plate 207 is fixedly connected to the surface of the activated carbon plate 206, and the activated carbon plate 206 is clamped to the surface of the filter tube 205 through the clamping plate 207. A handle 208 is fixedly connected to the surface of the clamping plate 207.

[0032] In a specific embodiment of this utility model, the setting of the clamping plate 207 facilitates the activation carbon plate 206 to be clamped onto the surface of the filter tube 205, and the handle 208 facilitates the movement of the activation carbon plate 206 and the clamping plate 207.

[0033] Specifically, the dust removal mechanism 3 includes a dust removal cylinder 301 installed on the upper surface of the water storage tank 1, and one end of the dust removal cylinder 301 is connected to the neutralization box 201. Multiple guide fan blades 302 are rotatably connected to the inner wall of the dust removal cylinder 301. A guide cylinder 303 is fixedly connected inside the dust removal cylinder 301. A servo motor 304 is fixedly connected inside the guide cylinder 303. Rotating fan blades 305 are fixedly connected to the surface of the output shaft of the servo motor 304.

An auxiliary pipe 309 is fixedly connected to the surface of the second blower fan 308, and the auxiliary pipe 309 is connected to the dust removal cylinder 301.

[0034] In a specific embodiment of this utility model, the servo motor 304 starts its output shaft to drive the rotating fan blade 305 to rotate. At this time, the exhaust gas enters the dust collector 301 axially and forms a high-speed rotating outer swirling flow and an inner swirling flow due to the shape of the dust collector 301. The outer swirling flow moves spirally downward along the inner wall of the dust collector 301, while the inner swirling flow turns on the surface of the conical cylinder 306 and is discharged along the dust collector 301. The centrifugal force generated by the rotating airflow causes the denser dust particles to be thrown towards the inner wall of the dust collector 301. After the dust particles come into contact with the inner wall of the dust collector 301, they lose their inertial force. At this time, the second blower fan 308 starts and sucks out the dust under the action of the dust collector pipe 307 and the auxiliary pipe 309.

[0035] Working principle: The servo motor 304 starts its output shaft, driving the rotating fan blades 305 to rotate. At this time, the exhaust gas enters the dust collector 301 axially. Due to the shape of the dust collector 301, it forms a high-speed rotating outer and inner swirling flow. The outer swirling flow spirals downwards along the inner wall of the dust collector 301, while the inner swirling flow turns on the surface of the conical cylinder 306 and is discharged along the dust collector 301. The centrifugal force generated by the rotating airflow causes denser dust particles to be thrown towards the inner wall of the dust collector 301. After contacting the inner wall of the dust collector 301, the dust particles lose their inertia. At this time, the second blower fan 308 starts and operates in the dust collector pipe. Dust is sucked out by the action of pipe 307 and auxiliary pipe 309, and then the exhaust gas enters the interior of neutralization box 201. At this time, the first blower fan 203 starts to drive the gas into the interior of neutralization cylinder 202. At the same time, the booster water pump 402 sucks out the liquid inside the water storage tank 1 and delivers it to the spray pipe 405 through the liquid guide pipe 404. Then, the alkaline solution is sprayed through the spray head 406 to neutralize the acidic gas in the exhaust gas. Then, the gas enters the interior of filter pipe 205 through connecting pipe 204. Then, it is filtered by activated carbon plate 206 to reduce the residue in the exhaust gas.
