[0026] Example 1

[0027] like Figure 1-6 As shown, it is the first embodiment of the utility model, which provides a waste gas treatment device for battery recycling, including a waste gas collection pipe 1 and a combustion tower 4, and also includes: a filtering mechanism 2, the filtering mechanism 2 is arranged on the right side of the waste gas collection pipe 1; a defluorination mechanism 3, the defluorination mechanism 3 is arranged on the right side of the filtering mechanism 2; a detection mechanism 5, the detection mechanism 5 is arranged on the right side of the combustion tower 4; an exhaust pipe 6 is fixedly installed on the right side of the detection mechanism 5, and a reflux pipe 7 is fixedly installed on the back of the detection mechanism 5.

[0028] like Figure 1 and Figure 6 As shown, the waste gas collection pipe 1 inputs the waste gas generated by battery recycling into the filtering mechanism 2 for filtering treatment to remove dust and particulate matter in preparation for subsequent catalytic combustion. The waste gas after filtering treatment enters the defluorination mechanism 3 for defluorination treatment. The waste gas with fluorine-containing components removed enters the combustion tower 4, and the volatile organic matter therein is removed by high-temperature combustion. The waste gas after combustion enters the detection mechanism 5. After detection, the qualified waste gas is discharged through the exhaust pipe 6, and the unqualified waste gas is introduced into the filtering mechanism 2 through the reflux pipe 7 to repeat the above purification operation.

[0029] Example 2

[0030] Reference Figure 1 、 Figure 2 and Figure 3 , which is the second embodiment of the present utility model, and this embodiment is based on the previous embodiment.

[0031] In this embodiment, the detection mechanism 5 includes a detection box 501, an exhaust gas analyzer 502, a controller 503, a first discharge valve 504 and a second discharge valve 505.

The detection mechanism 5 also includes a first sensor 506, a first indicator light 507, a second sensor 508 and a second indicator light 509. The first sensor 506 is fixedly mounted on the inner wall of one end of the exhaust pipe 6, the first indicator light 507 is fixedly mounted on the top of the first sensor 506, the second sensor 508 is fixedly mounted on the inner wall of one end of the return pipe 7, the second indicator light 509 is fixedly mounted on the top of the second sensor 508, the inner cavity of the detection box 501 is provided with a guide plate 5010, and the controller 503 is electrically connected to the first discharge valve 504 and the second discharge valve 505.

[0032] like Figure 1 、 Figure 2 and Figure 3As shown, the exhaust gas after combustion enters the detection box 501. The bucket shape formed by the guide plate 5010 in the detection box 501 gathers the exhaust gas and then flows through the exhaust gas analyzer 502. The exhaust gas analyzer 502 detects the composition of the exhaust gas passing through, and the detection results are fed back on the display screen of the controller 503. When qualified exhaust gas is detected, the controller 503 opens the first discharge valve 504 to discharge the exhaust gas through the exhaust pipe 6. When the exhaust gas passes through the exhaust pipe 6, the first sensor 506 detects the gas flow and the first indicator light 507 lights up. When unqualified exhaust gas is detected, the controller 503 opens the second discharge valve 505 to introduce the exhaust gas into the filter mechanism 2 through the return pipe 7 and repeats the purification operation. When the exhaust gas passes through the return pipe 7, the second sensor 508 detects the gas flow and the second indicator light 509 lights up, which makes it convenient for the staff to understand the working status of the device in time.

[0033] Example 3

[0034] Reference Figure 4 and Figure 5 , which is the third embodiment of the present utility model, is based on the first two embodiments.

[0036] like Figure 4 and Figure 5 As shown, the waste gas enters the defluorination tower 301 and flows along the defluorination channel 303.

[0037] During use, the waste gas collection pipe 1 inputs the waste gas generated by battery recycling into the filtering mechanism 2 for filtering treatment to remove dust and particulate matter. The filtered waste gas enters the defluorination mechanism 3 and flows along the defluorination channel 303. The spray assembly 304 is turned on and the spray head sprays the reaction solvent on the waste gas. The reaction solvent reacts with the fluorine-containing components in the waste gas to remove the fluorine-containing components in the waste gas. The waste gas with the fluorine-containing components removed enters the combustion tower 4 and is burned at high temperature to remove the volatile organic compounds therein. The waste gas after combustion enters the detection mechanism 5. The guide plate 5010 in the detection box 501 forms a bucket shape to gather the waste gas and then flows through the waste gas analyzer 502 The exhaust gas analyzer 502 detects the composition of the exhaust gas passing through, and the detection results are fed back to the display screen of the controller 503. When qualified exhaust gas is detected, the controller 503 opens the first discharge valve 504 to discharge the exhaust gas through the exhaust pipe 6. When the exhaust gas passes through the exhaust pipe 6, the first sensor 506 detects the flow of gas and lights up the first indicator light 507. When unqualified exhaust gas is detected, the controller 503 opens the second discharge valve 505 to introduce the exhaust gas into the filter mechanism 2 through the return pipe 7 and repeats the purification operation. When the exhaust gas passes through the return pipe 7, the second sensor 508 detects the flow of gas and lights up the second indicator light 509.

[0038] In summary: through the setting of the detection mechanism 5, the treated exhaust gas enters the detection box 501, and is guided by the guide plate 5010 to converge at the exhaust gas analyzer 502. After detection by the exhaust gas analyzer 502, and triggering the opening of the first discharge valve 504 or the second discharge valve 505, the qualified exhaust gas is discharged through the exhaust pipe 6, and the unqualified exhaust gas is guided to the filter tank 201 through the return pipe 7, and the purification treatment is repeated. The repetition of this process not only improves the efficiency and safety of the exhaust gas treatment, but also ensures the thoroughness of the exhaust gas treatment, thereby protecting the environment.
