Its function is to prevent short circuits between the positive and negative electrodes and allow gas and ion exchange between the positive and negative electrodes. During the production and manufacturing process of battery separators, a large amount of acidic, heavy metal, organic, inorganic and other harmful waste gases will be generated, which require the use of waste gas treatment equipment for environmental protection.

[0038] The waste gas generated in the production process of the battery diaphragm enters the processing chamber 101 in the box body 1 through the air inlet pipe 102. The airflow generated by the waste gas entering drives the power generation component 2 to work, generates electricity and stores it. The waste gas rises and passes through the filter component 3 for double-layer filtering and adsorption treatment. The filtered waste gas is detected by the electrochemical sensor 5 and then discharged from the exhaust pipe 104. When the detection does not meet the standard, the electrochemical sensor 5 sends a signal to the control panel. After receiving the signal, the control panel starts the drive component 8 and the suction fan 7031 to work. The drive component 8 drives the transmission component 9 to work, so that the blocking plate 6 and the closing plate 7032 move up synchronously.

[0040] Then the staff uses tools to remove the saturated glass fiber filter 301 and activated carbon filter 302 and replace them with new filters, and then opens the solenoid valve of the intake pipe 102 through the control panel to supply air.

[0045] The auxiliary filter tube 10 can re-filter the waste gas that does not meet the filtering standards because the filter component 3 is close to saturation. The substandard gas enters the auxiliary filter tube 10 through the first air duct 702, and is filtered through three fiber activated carbon filters 1003. The treated gas enters the second air duct 702 and is discharged. When the filter component 3 is replaced and no more gas enters the first air duct 701, the staff can use tools to remove the bolts on the plate 1002, so that the auxiliary filter tube 10 is removed from the bottom of the treatment box 7, and placed in the desorption device to desorb the internal fiber activated carbon filter 1003.

[0049] Step 1: Waste gas filtration treatment: the waste gas generated by the production of battery diaphragms enters the processing chamber 101 through the air inlet pipe 102, is filtered by the filter component 3, and then is discharged. After the waste gas enters, the airflow can drive the power generation component 2 to perform power generation operation;

[0050] Step 2: Detection of gas after filtration. The electrochemical sensor 5 detects the filtered gas.

[0052] The working principle of the present invention is:

[0053] The waste gas generated in the production process of the battery diaphragm enters the processing chamber 101 in the box body 1 through the air inlet pipe 102. The airflow generated by the waste gas entering drives the fan blades 202 to rotate. The generator 204 generates electricity through the rotation of the fan blades 202 and stores it in the battery 205 through the wire. The waste gas rises and passes through the filter component 3 for double-layer filtration and adsorption treatment. The filtered waste gas is detected by the electrochemical sensor 5 and then discharged from the exhaust pipe 104. When the detection does not meet the standard, the electrochemical sensor 5 sends a signal to the control panel. After receiving the signal, the control panel starts the drive component 8 and the suction fan 7031 to work, driving the drive motor 802 in the drive component 8. When the drive motor 802 works, its output end drives the active bevel gear 803 to rotate, and the active bevel gear 803 drives the meshing driven bevel gear 804 to rotate. The driven bevel gear 804 drives the first connecting shaft 805 to rotate. The rotation of the first connecting shaft 805 drives the rope winding discs 8052 at both ends and the second transmission wheel 90 in the transmission component 9. 2 rotates, the second transmission wheel 902 drives the first transmission wheel 901 to rotate through the transmission chain 903, the first transmission wheel 901 drives another first transmission wheel 901 to rotate through the transmission shaft 904, the first transmission wheel 901 drives another second transmission wheel 902 to rotate through the transmission chain 903, the second transmission wheel 902 drives the second connecting shaft 807 to rotate, the rotating second connecting shaft 807 drives the rope winding drum 8052 to rotate, so that the three rope winding drums 8052 rotate synchronously to control the lifting rope 8052. 053 is wound, and the lifting rope 8053 drives the blocking plate 6 and the closing plate 7032 to move upward due to the winding, completing the blocking of the exhaust pipe 104 and the dredging of the square suction pipe 703. At this time, the suction fan 7031 sucks the exhaust gas above the filter component 3 into the first air duct 701, and the substandard gas enters the auxiliary filter pipe 10 through the first air duct 702, and is filtered through three fiber activated carbon filters 1003. The treated gas enters the second air duct 702 and is discharged;
