5. The hazardous gas spray absorption device for waste battery recycling production lines according to claim 1, characterized in that, The control panel (4) is internally equipped with a processor, a data acquisition module, a self-test feedback module and a signal execution module; The data acquisition module is used to collect the atomization absorption condition information of harmful gases during the operation of the device and send it to the self-test feedback module. The atomization absorption condition information consists of the gas flow factor, the internal pressure factor and the gas filter residue factor. The gas flow factor is the difference between the harmful gas in the external injection device and the purified gas in the internal outlet device collected by the gas flow sensor. The internal pressure factor is the set of internal gas pressure fluctuation data collected by the gas pressure sensor. The gas filter residue factor is the product of the amount of filter residue accumulated in the slag collection chamber (502), the tower base (2) and the lower circulation mechanism (7) collected by the metering sensor. The self-test feedback module then uses the received information on the atomization absorption status of harmful gases during operation to monitor and analyze the atomization absorption process of the device. The specific steps are as follows: A: Obtain the atomization absorption condition information of harmful gases during operation, and label the gas flow factor, internal pressure factor, and gas filter residue factor as Q, W, and E, respectively; B: According to the formula The atomization absorption level R of harmful gases during operation is obtained, where q, w, and e are process correction factors, with e greater than q, greater than w, and ; C: When the atomization absorption level R of harmful gases during operation is greater than or equal to the preset value r or less than the preset value r, an intervention control signal or a continuous operation signal will be generated respectively. The intervention and control signal and the continuous operation signal corresponding to the atomization absorption of harmful gases during the operation process are sent to the signal execution module via the processor. If the signal execution module receives the intervention and control signal, it immediately controls the water pump (302) to work; if the signal execution module receives the execution operation signal, it does not perform any processing.
