[0043] More specifically, an exhaust fan 8 is installed at the top of the purification tank; and three supporting legs 9 are arranged at the bottom.

[0044] It should be noted that in actual use of the exhaust gas purification device for battery bottom guard plate production provided by the present invention, the purification tank is placed vertically.

[0045] The first liquid collecting protrusion 202 allows the acid solution to flow into the first liquid collecting disk 201 , and the second liquid collecting protrusion 402 allows the alkali solution to flow into the second liquid collecting disk 401 .

[0046] The present invention also provides an exhaust gas purification method for battery bottom guard plate production, and its working principle and specific process are as follows:

[0047] ① Exhaust gas first enters the dust removal chamber 1 from the air inlet pipe 101, and the air distribution pipe 102 evenly distributes the air. Tap water is sprayed from the dust removal sprayer 103 to form countless fine droplets. After being fully mixed with the exhaust gas, the dust and other substances in the exhaust gas are absorbed in the tap water. The wastewater generated by washing and dust removal is discharged into the workshop sewage treatment system through the wastewater discharge valve 104 for treatment.

[0048] ②Then the waste gas rises and enters the oxidation chamber 2. At the same time, the acidic water above flows into the oxidation chamber 2 from the pickling chamber 3. The acidic water dissolves calcium sulfite and iron oxide to form sulfite and iron ions. The iron ions are oxidizing. These two ions react in contact. The sulfite is oxidized to form sulfate free radicals. The sulfate free radicals have a strong oxidizing effect on the pollutants dissolved in the wastewater, and the pollutants are oxidized and decomposed.

[0049] ③ The waste gas rises into the pickling chamber 3 and contacts the acid solution sprayed from the acid sprayer 301. The alkaline substances in the waste gas react chemically with the acid, and the reaction products flow into the first liquid collecting plate 201 at the bottom along with the acid solution.

[0050] ④ The gas continues to rise and enters the neutralization chamber 4 to contact the alkali solution sprayed by the alkali solution sprayer 403. The pollutants in the gas react chemically with part of the sodium hydroxide, and the reaction product flows into the second liquid collecting disk 401 at the bottom along with the alkali washing liquid; at the same time, part of the sodium hydroxide neutralizes the acidic gas, which is beneficial to the subsequent biochemical reaction.

[0051] ⑤ Then the gas enters the biochemical chamber 5, and the organic pollutants in the waste gas are absorbed by the microorganisms in the biochemical filler 502 and undergo biochemical reactions, and some pollutants are biochemically removed.

[0052] ⑥Then the gas enters the dehumidification chamber 6. After entering the dehumidifier 601, the gas passes through a series of bends and is discharged from the top. Due to the mass and kinetic energy of the water droplets, when passing through the bends, they collide with the inner surface of the dehumidifier bend and bounce back and fall under the action of gravity. The liquid droplets in the gas are intercepted here.

[0053] ⑦ Then the gas enters the adsorption chamber 7, where the substances and droplets contained in the gas are intercepted and adsorbed by the activated carbon 702. At this point, the exhaust gas is processed into clean gas, and the exhaust fan 8 discharges the clean gas to achieve standard emission.

[0054] Those skilled in the art can understand that the above-mentioned embodiments are specific examples for implementing the present application, and in practical applications, various changes can be made to them in form and detail without departing from the spirit and scope of the present application. Any person skilled in the art can make their own changes and modifications without departing from the spirit and scope of the present application, so the scope of protection of the present application shall be based on the scope defined in the claims.
